Forward-Looking Statements and Market Data
Part I
This Annual Report on Form 10-K (the Annual Report), contains forward-looking statements within the meaning of Section 21E of the
Securities Exchange Act of 1934, as amended (the Exchange Act). All statements other than statements of historical facts contained in this
Annual Report, including statements regarding our future results of operations and financial position, business strategy, current and future
product offerings, reimbursement and coverage, the expected benefits from our commercial arrangements with third parties, research and
development costs, timing and likelihood of success and plans and objectives of management for future operations, are forward-looking
statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results,
performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the
forward-looking statements. This Annual Report also contains estimates and other statistical data made by independent parties and by us
relating to market size and growth and other data about our industry. This data involves a number of assumptions and limitations, and you
are cautioned not to give undue weight to such estimates. In addition, projections, assumptions and estimates of our future performance and
the future performance of the markets in which we operate are necessarily subject to a high degree of uncertainty and risk.
In some cases, you can identify forward-looking statements by terms such as "believe," "may," "will," "should," "predict," "goal," "strategy,"
"potentially," "estimate," "continue," "anticipate," "intend," "could," "would," "project," "plan," "expect," "seek," and similar expressions that
convey uncertainty of future events or outcomes, are intended to identify forward-looking statements.
The forward-looking statements in this Annual Report are only predictions. We have based these forward-looking statements largely on our
current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and
results of operations. These forward-looking statements speak only as of the date of this Annual Report and are subject to a number of risks,
uncertainties and assumptions described under the sections “Risk Factors” and elsewhere in this Annual Report. Because forward-looking
statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond
our control, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected
in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-
looking statements. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and
it is not possible for management to predict all risk factors and uncertainties. Except as required by applicable law, we undertake no
obligation to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future
events, changed circumstances or otherwise.
We use our trademarks in this Annual Report as well as trademarks, tradenames and service marks that are the property of other

Company Overview
Item 1. Business.
Exagen exists to provide clarity in autoimmune disease decision making with the goal of improving patients' clinical outcomes. We have
developed and are commercializing a portfolio of innovative testing products, under our AVISE brand, which allow for the differential
diagnosis, prognosis and monitoring of complex autoimmune and autoimmune-related diseases. We believe our strong focus and extensive
background in the field of rheumatology, combined with our commitment to exceptional customer service and support, position us well to
respond to the needs of rheumatologists and the patients they serve.
®
®
®
We commercially launched our lead testing product, AVISE CTD, in 2012. AVISE CTD enables differential diagnosis for patients presenting
with symptoms indicative of a wide variety of connective tissue diseases (CTDs) and other related diseases with overlapping symptoms. The
comprehensive nature of AVISE CTD allows for the testing of a number of relevant biomarkers in one convenient blood draw (as opposed to
testing serially for individual biomarkers, which adds time and cost to the diagnostic process). We believe AVISE CTD may provide clinical
utility for more than 41 million individuals in the United States, encompassing patients with conditions like systemic lupus erythematosus
(SLE); rheumatoid arthritis (RA); Sjögren’s syndrome, antiphospholipid syndrome (APS); other autoimmune-related diseases, such as
autoimmune thyroid; and disorders that mimic these diseases, such as fibromyalgia. There is an unmet need to add clarity for
rheumatologists in their CTD clinical evaluations. As a result, we believe there is a significant market opportunity for our tests, which enable
the differential diagnosis of these diseases, particularly, for potentially life-threatening diseases such as SLE.
®
®
®
Included in AVISE CTD is our proprietary AVISE Lupus test, which enables the diagnosis of SLE based on levels of erythrocyte bound C4d
(EC4d) and B cell C4d (BC4d); along with anti-nuclear antibodies (ANA) and double-stranded DNA antibodies (ds-DNA). AVISE Lupus
provides rheumatologists and their patients with sensitive and specific results that allow for more accurate and potentially faster differential
diagnosis of SLE, as compared to other currently-marketed testing methods. Beyond SLE, AVISE CTD also allows rheumatologists to
accurately diagnose other overlapping autoimmune and autoimmune-related diseases (including RA), with the same blood sample.
®
®
®
®
Our AVISE SLE Monitor test leverages CB-CAPs technology to measure biomarkers that offer insight into a patient’s disease activity. This
test is designed to enable rheumatologists to effectively assess and optimize therapeutic intervention in patients diagnosed with SLE.
Depending on disease severity, AVISE SLE Monitor may be utilized by patients multiple times a year throughout their lives.
®
®
®
Our RA testing products include AVISE MTX and AVISE Anti-CarP. AVISE MTX is a drug monitoring test designed to aid in the
optimization of methotrexate therapy, the standard of care and first-line therapy for patients with RA. AVISE MTX is based on our
methotrexate polyglutamate (MTXPG) technology that measures blood levels of MTXPGs, the active metabolite of methotrexate linked to
disease control in RA patients. Measuring MTXPGs allows rheumatologists to identify patients presenting with inadequate exposure to
®
methotrexate, enabling them to optimize dosing and achieve therapeutic levels commensurate with adequate disease control. AVISE Anti-
CarP was developed by the Leiden University Medical Center and measures anti-carbamylated protein antibody (anti-CarP). We introduced it
as a biomarker-driven RA prognostic test, through a distribution agreement with Werfen USA, LLC, with the goal of identifying patients prone
to more severe disease.
®
®
®
We market our AVISE testing products using our specialized sales force. Since the launch of AVISE CTD in 2012 and through
December 31, 2023, we have delivered approximately 887,000 of these tests. For the year ended December 31, 2023, 137,650 AVISE CTD
tests were delivered, representing an approximate 2% increase over 2022. In the fourth quarter of 2023, the number of ordering healthcare
providers reached 2,383 compared to 2,419 in the same period in 2022.
®
®
In addition, we continue to populate a growing proprietary database of de-identified patient test results from our clinical studies and our
clinical laboratory. We believe the insights from these results have the potential to unlock value for pharmaceutical and biotechnology
companies in the development and commercialization of therapeutics. We believe we also have the ability to further leverage our database to
optimize patient selection in clinical trials for companies developing therapeutics for autoimmune and autoimmune-related diseases.
Our Strategy
We address the unmet needs of those suffering from debilitating and chronic autoimmune disorders through aiding in differential diagnosis,
prognosis, monitoring and therapeutic selection, to ultimately improve clinical outcomes for patients. The key tenets of our business strategy
include:
2
▪
®
Focus on our flagship product, AVISE CTD. We have demonstrated a solid track record of commercial growth of our AVISE
CTD test. We believe we are uniquely positioned to continue expanding our commercial presence within the autoimmune disease
market by leveraging our specialized sales force and expansive network of relationships with rheumatologists across the United
States. Using our specialty laboratory focused on rheumatology, we plan to build upon industry-leading quality, service and
technology to support strong AVISE CTD adoption and continue to grow our ordering physician base.
®
®
▪ Continue developing innovative testing products, using clear criteria for R&D projects and commercialization milestones.
We intend to leverage our protein and molecular assay development capabilities, bioinformatic team and proprietary technologies to
pursue the development of additional testing products designed to have superior clinical utility for CTDs. We undertake research
projects that have the potential for impactful results and address the top consumer needs in the rheumatology space. The research
projects we support are those that we believe will have a competitive advantage (such as using proprietary technology), a pathway
for reimbursement and an established evidence development plan with sufficient market size. Criteria for developed products that we
ultimately commercialize include Medicare coverage (specific to patient population), proprietary value-based pricing, published
clinical utility and a strategy for medical guideline inclusion.
▪ Maintain meaningful margin. We seek to maintain meaningful margin by continuing to focus on increasing operating leverage
through the implementation of certain internal initiatives, such as leveraging validation, utility and reimbursement-oriented clinical
studies to facilitate payor coverage of our testing products. We center our efforts on long-term reimbursement and average sales
price (ASP) growth. This strategy includes optimizing revenue cycle practices, focusing managed care efforts on medical policy
expansion and continuing to educate insurance payors on the published, real-world evidence of the clinical utility of our testing
products, demonstrating healthcare cost savings and reductions in time to diagnosis.
We also seek to improve our per-test costs by focusing on profitable, core test offerings, minimizing fixed costs and overhead, and
focusing our laboratory resources on AVISE CTD optimization. Additionally, we employ a streamlined salesforce covering territories
which are designed to achieve the most efficient and effective reach and frequency for the promotion of AVISE CTD.

Autoimmune and Connective Tissue Diseases (CTDs)
Autoimmune diseases encompass a broad range of serious, chronic and debilitating conditions in which a person’s immune system creates
antibodies that mistakenly react against normal healthy tissues, causing inflammation and irreversible tissue damage. These antibodies are
called autoantibodies and their detection through blood tests can help diagnose, prognose and monitor the course of autoimmune diseases.
However, knowing when to test and which autoantibody to test for is challenging due to the vagueness of symptoms, the unexplained flaring
and remission of symptoms, and the many conditions which can mimic autoimmune disease. Early and accurate diagnosis of the conditions
causing these overlapping symptoms is critical, as an incorrect diagnosis can lead to toxicity from inappropriate medications, irreversible
tissue damage and other comorbidities associated with uncontrolled disease. There is no known cause or cure for these chronic conditions
and current treatment interventions are targeted at managing symptoms and limiting disease progression.
CTDs are a sub-category of autoimmune diseases involving inflammation of the joints, tissues and internal organs. Persons with CTDs often
present to their rheumatologist with complaints of joint pain, fatigue, unexplained fever, inflammation, rash, stiffness and muscle aches.
These symptoms overlap among numerous CTDs, including SLE, one of the most severe CTDs, which historically has been difficult to rule
out, as well as other autoimmune-related diseases and other disorders that mimic these diseases, such as fibromyalgia. The National
Institute of Environmental Health Sciences estimates that there are approximately 41 million patients in the United States with existing cases
of autoimmune diseases. Of these patients, we estimate approximately seven million are potentially referable to rheumatologists and would
be candidates for an AVISE CTD test, representing a total addressable market of approximately $7.5 billion, based on the current Medicare
allowable reimbursement rate. We estimate the total addressable market for our AVISE testing products to be approximately $9.2 billion,
based on estimated patient populations, the current Medicare allowable reimbursement rate and testing frequencies.

Systemic Lupus Erythematosus
SLE, the most common and severe form of lupus, is a chronic, inflammatory disorder that can damage any part of the body, including the
skin, joints and internal organs. The blood of a person afflicted with SLE contains autoantibodies, which are the cause of the inflammation
and organ damage and are one indicator of immune system abnormalities. SLE is characterized by a rise in symptoms and/or abnormal
laboratory test results. SLE
3
varies in severity, from mild cases to those in which significant and potentially fatal damage occurs to vital organs such as the brain, heart,
kidneys and lungs. Detection of these autoantibodies can assist rheumatologists in the diagnosis of SLE. Diagnosis of SLE allows
rheumatologists to initiate the most appropriate therapy to minimize irreversible organ damage and reduce morbidity and mortality. Current
treatment for SLE involves the use of antimalarials, corticosteroids, immunosuppressants and biologic agents to prevent or suppress active
disease or flares.
Standard laboratory tests for diagnosing SLE include measuring immunological biomarkers, such as ANA, anti-double stranded DNA (anti-
dsDNA) and other autoantibody tests. ANA are a group of autoantibodies produced by a person’s immune system when it fails to adequately
distinguish between self and non-self. The ANA test detects these autoantibodies in the blood and is a useful screening tool for SLE and
other autoimmune and autoimmune-related diseases. The vast majority of SLE patients test positive for ANA. However, the high sensitivity of
ANA for SLE is counterbalanced by somewhat poor specificity. According to Dinse et al. (2022), who investigated the increasing prevalence
of ANA in the United States using data from the National Health and Nutrition Examination Survey, approximately 0.7%–2.4% of individuals
with a positive ANA test have SLE. This lack of specificity leads to many inappropriate non-autoimmune referrals to the rheumatologist from
primary care physicians. For example, it has been reported that 30% of fibromyalgia patients may test positive for ANA, potentially generating
as many as four million inappropriate rheumatology referrals. In addition, the Dinse et al. study reported the estimated prevalence of a
positive ANA test in the normal, healthy, U.S. population to be 16.1% (approximately 41.5 million people), indicating a significant need for a
highly specific test for this disease.
Anti-dsDNA are autoantibodies that target a person’s double-stranded DNA. The anti-dsDNA antibody test is a very specific test for SLE, as
anti-dsDNA antibodies are rarely found in autoimmune diseases other than SLE. A strongly positive anti-dsDNA antibody test makes it very
likely that a person has SLE, although if the test is negative it does not necessarily rule out SLE. Many people with SLE have a negative anti-
dsDNA antibody test, reaffirming the need for an effective testing product which adds clarity to the rheumatologist’s clinical assessment.
Activation of the complement system is an integral part of the disease process of SLE. Thus, rheumatologists measure components of the
complement system, including serum levels of C3 and C4, to help diagnose SLE and monitor SLE disease activity. In 2012, the Systemic
Lupus Collaborating Clinics added low C3 and low C4 as immunologic criteria for classifying SLE. In active SLE, C3 and C4 complement
proteins are consumed and broken down to fragments, known as complement activation products. Therefore, low levels of C3 and C4
suggest a diagnosis of SLE and that the disease is active. However, variability in the levels of C3 and C4 can occur due to factors unrelated
to SLE disease presence or disease activity, making them less reliable as biomarkers for SLE. For example, C3 and C4 are acute-phase
reactants and produced during inflammation. As a result, many SLE patients have normal complement levels even when the disease is
active. Although relatively specific for SLE, low complement levels can also be seen in certain chronic infections, including non-lupus-related
kidney inflammation, severe liver disease and other autoimmune diseases. CB-CAPs are formed when the fragments of complement
activation products from C4 bind permanently to circulating cells such as red blood cells, b-cells and platelets. This binding lasts for the life of
the cell and represents a more stable and reliable indicator of complement activation than measuring C3 and C4 alone.
In March 2011, the first new biologic targeting treatment of SLE in over 50 years, GSK’s Benlysta , was approved by the U.S. Food and Drug
Administration (the FDA). In December 2020, the FDA approved this biologic drug for the treatment of adult patients with active lupus
nephritis who are receiving standard therapy. Since Benlysta 's approval, there have been a number of drug development programs that
have failed in SLE, which may suggest that guidelines for classifying SLE patients and the endpoints used to determine clinical effectiveness
have not adequately addressed the complexity of the disease process and its heterogeneous population.

Rheumatoid Arthritis
RA is a chronic, systemic autoimmune disease in which the immune system attacks the joints and can also affect other organ systems. The
annual incidence and prevalence of RA in the United States is estimated to be 135,000 and 1.5 million, respectively. Patients suffering from
RA develop joint damage that is associated with painful inflammation and often progresses to irreversible damage of cartilage and bone,
leading to significant disability and a reduction in quality of life and the ability to work. Early diagnosis and effective treatment of RA is
critically important to prevent erosive bone or joint damage and disability. Rheumatologists are compelled to reach a definitive diagnosis
quickly and administer effective treatment.
Diagnosis of RA involves performing a complete medical history with physical and/or radiographic examination of the number and distribution
of swollen, tender and painful joints that have persisted for more than six weeks. Laboratory testing for rheumatoid factor (RF), anti-cyclic
citrullinated peptide (CCP) antibodies and testing for
4
general, nonspecific inflammation with erythrocyte sedimentation rate (the ESR) and C-reactive protein tests are used to assist in the
diagnosis.
The standard of care for the treatment of RA involves the use of Disease Modifying Anti-Rheumatic Drugs (DMARDs) which have shown, in
clinical studies, the ability to slow or stop disease progression. Methotrexate remains the most commonly used DMARD, due to its low cost
and effectiveness, as well as the extensive clinical experience with its use. It is estimated that approximately 90% of RA patients in the
United States, or 1.3 million patients, are treated with methotrexate, either as a monotherapy or in combination with another DMARD.
Biologics DMARDs are proteins that have been genetically modified to target cellular components of the immune system that attack healthy
tissues, causing the symptoms of RA. They are a targeted form of therapy, which makes them different from traditional RA treatments, such
as methotrexate. The first FDA approved biologics for RA were the anti-TNFs. The anti-TNFs dominate the therapy for RA and generally are
the first biologics chosen to augment methotrexate when patients are not achieving a satisfactory response.
Our Solution
We market testing products under our AVISE brand that allow for the differential diagnosis, prognosis and monitoring of complex
autoimmune and autoimmune-related diseases, including SLE and RA. We are focused on leveraging our sales channel targeting the
approximately 4,500 rheumatologists across the United States to promote use of our product portfolio.
®
Our Proprietary Technologies
We believe the competitive advantage for our testing products is supported by core proprietary technology, namely our AVISE Lupus test.
®
AVISE Lupus Test
®
®
®
Our AVISE Lupus test, which we offer as a stand-alone test and as part of our AVISE CTD test panel, is a proprietary, clinically validated
method to aid in the diagnosis of SLE that provides a significant improvement in sensitivity, relative to the current standard of care. The
AVISE Lupus test leverages CB-CAPs technology, which determines the blood levels of complement activation proteins permanently
deposited on hematopoietic cells. The determination of complement proteins in a patient’s blood is a mainstay in clinical laboratory science,
and state-of-the-art methods traditionally rely on measurement of serum or plasma levels of soluble complements. C3 and C4 are the most
commonly determined complement proteins in the blood and the precursors to activation of complement proteins into biologically active
breakdown products. However, there are limitations with measuring C3 and C4 blood levels as indicators of complement activation. For
example, increased synthesis of C3 and C4 by the liver can offset increased C3 and C4 breakdown during activation of the complement
cascade, resulting in no change in serum levels. While the limitations and drawbacks of measuring standard components of the complement
system, such as C3 and C4, are well recognized by the medical community, these laboratory biomarkers are part of international guidelines
for the classification of SLE.
®
We believe the availability of novel complement biomarkers combined with algorithmic interpretations, as a support or replacement of
standard C3 and C4 measures, is of great value for rheumatologists and their patients. CB-CAPs technology directly measures protein
products of complement activation, such as C4d, the product of C4 activation. These complement activation products become stably
attached to surfaces of circulating blood cells to become CB-CAPs. As such, the determination of CB-CAPs in the blood provides benefits
when compared to the traditional complement measurement. These include the stable, accurate and unequivocal information of complement
activation that enable consistent measurement and an improved ability to assess and monitor changes in biological activity related to
activation of the complement system. In a clinical validation study published in 2014 by Chaim Putterman, et al. (the 2014 Study), EC4d and
BC4d showed 22% higher sensitivity (66%) than C3 and C4 (44%) in diagnosing SLE, with specificity fixed at 91%.
®
®
Our proprietary AVISE Lupus test integrates EC4d and BC4d with 8 autoantibodies to yield a quantitative and qualitative assessment of SLE
risk. The AVISE Lupus test was designed to improve upon the diagnostic sensitivity of conventional biomarkers used to diagnose SLE while
maintaining a high degree of specificity. In the aforementioned 2014 Study, the AVISE Lupus test demonstrated 80% sensitivity for SLE
(meaning 8 out of 10 diagnosed SLE patients tested positive) and 86% specificity for SLE (meaning 86% of non-SLE control subjects with
other rheumatic conditions tested negative). A later study published in 2022 by Tyler O’Malley, et al., compared the clinical utility of the
AVISE Lupus test to the conventional biomarker strategy in the diagnosis of SLE, demonstrating 6-fold increased odds of SLE diagnosis
and 3-fold increased odds of treatment initiation with a
®
®
5
positive AVISE Lupus result. We believe this patent-protected test gives us a significant advantage over our competitors.
®
Testing Products
Since inception, we have been committed to developing and commercializing innovative testing products that address the challenges
rheumatologists face in differentially diagnosing, prognosing and monitoring complex autoimmune and autoimmune-related diseases. We
estimate the total addressable market for our AVISE testing products to be approximately $9 billion, based on estimated patient populations,
the current Medicare allowable reimbursement rate and testing frequencies.
®
Diagnosis
®
AVISE CTD
®
®
®
Our lead testing product, AVISE CTD, is a comprehensive test that aids in the differential diagnosis of SLE versus other common CTDs.
AVISE CTD includes our proprietary AVISE Lupus test, which leverages CB-CAPs technology to specifically measure activation of the
complement system. In addition to testing for SLE, AVISE CTD tests for a series of biomarkers in one convenient blood draw to aid in the
differential diagnosis of a wide variety of CTDs and other diseases which can be challenging to diagnose as a result of overlapping
symptoms. These diseases include SLE; RA; Sjögren’s syndrome; APS; other autoimmune-related diseases, such as autoimmune thyroid;
and other disorders that mimic these diseases, such as fibromyalgia. Use of our test significantly enhances the rheumatologist's ability to
exclude SLE and differentiate other CTDs, resulting in a clearer assessment and ultimately increasing the efficiency and accuracy of the
broader diagnostic process. The clinical performance of our proprietary AVISE Lupus test, combined with the convenience of a single blood
draw, make AVISE CTD an attractive choice among rheumatologists.
®
®
®
®
AVISE Lupus
®
®
Our proprietary AVISE Lupus test is the cornerstone of the SLE assessment within our more comprehensive AVISE CTD testing product.
AVISE Lupus begins by quantifying the level of CB-CAPs biomarkers (EC4d and BC4d) in the patient’s blood. These biomarkers are
elevated in patients with SLE compared to patients with other CTDs. Next, the AVISE Lupus test integrates these cell-bound complement
products with 8 autoantibodies to yield a quantitative and qualitative assessment of SLE risk. Rheumatologists choose to order the
comprehensive AVISE CTD test or the more focused AVISE Lupus test based on medical necessity, which is determined by each patient’s
symptoms and medical history.
®
®
®
®
®
AVISE APS
®
AVISE APS consists of a specialized panel of autoantibody tests. This test aids in both the diagnosis and management of APS, a hyper-
coagulation state leading to thrombosis, pregnancy complications and even death. Rheumatologists would typically request the AVISE APS
test in patients who initially tested positive for one or more APS biomarkers contained in AVISE CTD, or in the management of patients
experiencing a high-risk pregnancy.
®
®
AVISE Vasculitis AAV
®
®
AVISE Vasculitis AAV utilizes a testing panel of individual analytes designed to provide physicians with rapid and reliable results in the
assessment and monitoring of anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV). AAV is a group of autoimmune
diseases characterized by vascular inflammation and damage. Early signs and symptoms vary greatly and are not always indicative of the
severity of the disease. Rapid and accurate testing is essential to prevent death and long-term disability.
Prognosis
AVISE SLE Prognostic
®
®
AVISE SLE Prognostic is a panel of autoantibodies that have established predictive value for assessing the potential for complications
affecting the kidney, brain and cardiovascular system, including lupus nephritis, lupus psychosis, strokes and heart attacks related to lupus.
Rheumatologists rely on insights from the AVISE SLE Prognostic test to help tailor their treatment approach.
®
AVISE Anti-CarP
®
6
®
AVISE Anti-CarP, developed by the Leiden University Medical Center, measures anti-CarP. We introduced it as a biomarker-driven RA
prognostic test, through a distribution agreement with Werfen USA, LLC, with the goal of identifying patients prone to more severe disease.
With the introduction of AVISE Anti-CarP in 2018, we became the first commercial laboratory to make testing for anti-CarP available in the
United States. This test uniquely addresses two major challenges facing rheumatologists today – (1) patients presenting with RA symptoms
but lacking the common confirmatory blood tests for anti-RF or anti-CCP, known as sero-negative patients, and (2) the lack of a serologic
indicator, which indicates a poor prognosis and helps guide treatment decisions. Anti-CarP can be positive in up to 26% of RA patients who
are negative for anti-CCP. Furthermore, RA patients positive for Anti-CarP have an increased risk for more severe RA disease, including
permanent joint damage.

Monitoring
AVISE SLE Monitor
®
®
AVISE SLE Monitor is a blood test that employs CB-CAPs technology and is intended to assess the condition of a patient that has been
diagnosed with SLE. It offers a unique combination of biomarkers that measure for EC4d, which has shown greater accuracy in tracking
disease activity than C3 and C4, which is associated with thrombosis risk in SLE. AVISE SLE Monitor offers additional insight into a patient’s
disease activity as well as possible adverse events. Rheumatologists have limited methods for evaluating the extent of disease activity taking
place inside the body of an SLE patient. They rely on imperfect biomarkers, overt symptoms or flares and patient reported history. All of these
leave the rheumatologists looking for greater insights, especially in cases where patients under report their symptoms, a bias which
healthcare providers may not fully appreciate. AVISE SLE Monitor demonstrates correlation to SLE disease activity and is therefore
designed to enable rheumatologists to effectively assess and optimize therapeutic intervention in patients diagnosed with SLE. Additionally,
AVISE SLE Monitor measures EC4d, anti-C1q, C3, C4 and anti-dsDNA which can assist physicians with managing their lupus nephritis
patients. Depending on disease severity, our AVISE SLE Monitor testing product may be utilized by patients multiple times a year and
throughout their lives. We believe AVISE SLE Monitor will play an increasingly important role in the management of SLE patients and further
solidify the role and relationship of AVISE testing products for these patients.

AVISE MTX
®
AVISE MTX is a patented and validated blood test that precisely measures blood levels of MTXPG, the active metabolite of methotrexate
linked to disease control in RA patients. There is large variability in the way patients absorb and metabolize methotrexate, leaving
rheumatologists unsure of what steps to take when a patient has an inadequate response. Methotrexate is the most widely prescribed drug
by rheumatologists in the treatment of RA. Measuring MTXPGs allows rheumatologists to identify patients presenting with inadequate
exposure to methotrexate, enabling them to optimize dosing and achieve therapeutic levels commensurate with adequate disease control.
When faced with a patient who is not responding to methotrexate therapy, the options include increasing the dose, switching to a parenteral
delivery method and/or advancing to a more costly biologic therapy. AVISE MTX provides crucial information as to whether a patient has
achieved MTXPG blood levels consistent with an appropriate response to methotrexate, also known as the therapeutic level, or if the MTXPG
blood levels are too low to produce adequate effects. MTXPG blood levels are actionable clinical utility checkpoints and can help clinicians
identify causes for a lack of response to methotrexate, such as poor activation to active metabolites, underexposure secondary to poor
absorption or poor compliance, all of which are limiting factors to the achievement of a robust clinical response with this first-line treatment.
AVISE MTX can allow rheumatologists to make more informed therapeutic decisions in their efforts to optimize methotrexate therapy and
give patients their best chance at achieving an optimal response.
®
®
®
AVISE HCQ
®
AVISE HCQ is a blood test designed to help rheumatologists objectively monitor levels of hydroxychloroquine (HCQ), in whole blood as they
treat patients with SLE and other CTDs, including RA. HCQ is typically prescribed to patients to control SLE disease activity and prevent
flares. However, there is large variability in the response to HCQ therapy, the drug can sometimes take weeks or months to have a
therapeutic effect and compliance has been documented to be an issue in CTD patients. We believe measuring HCQ makes the patient
accountable, and also helps to determine whether HCQ blood levels are adequate and consistent with clinical efficacy. The addition of new
and costly biologic therapies approved for the treatment of SLE may drive interest by all healthcare stakeholders, especially payors, to adopt
an approach that optimizes a generic drug before advancing to a costlier alternative.
Test Reports
7
®
®
We provide the results of our AVISE testing products in a comprehensive and easy-to-understand test report, typically sent to
rheumatologists within five business days following receipt of the blood specimen. As shown below, the result of the AVISE Lupus portion of
the AVISE CTD report displays a gradient illustrating the likelihood of the presence of lupus, which facilitates interpretation and discussion of
the result with the patient versus only reporting a numerical value. In addition, all biomarker results for AVISE CTD are reported and
organized by disease state, providing clarity and convenience for the rheumatologists. A sample of the full AVISE CTD report is shown

Our Pipeline and Growth Opportunities
We regularly confer with national experts in the clinical management of rheumatic autoimmune diseases to help guide the organization’s
leadership team on the design and execution of research projects, as well as weigh-in on known and anticipated advances in technologies
affecting clinical management of autoimmune diseases. We believe there is significant potential to capitalize on our proprietary technologies
by integrating with commercially validated biomarkers to develop testing products with superior clinical utility. The complement pathway is
widely implicated in the pathogenesis of a variety of conditions, including autoimmune diseases and organ transplant rejection. We believe
the stability and reliability of CB-CAPs technology, in combination with increased specificity provided by our patent-protected AVISE Lupus
test, will allow us to produce meaningful and differentiated proprietary solutions for rheumatologists.
®
TC4d, TIgG and TIgM Biomarkers
Our collaborative efforts with the Allegheny Health Network Research Institute (AHN) have resulted in further development of three
innovative biomarkers (TC4d, TIgG, and TIgM), for which we obtained an exclusive, worldwide license from AHN in May 2021. These
markers exhibit a high degree of specificity for lupus and are more sensitive for lupus compared to conventional biomarkers. The objective is
to incorporate these three biomarkers into the AVISE Lupus test in order to enhance the diagnostic sensitivity for lupus beyond its current
80% level. Additionally, TC4d represents a proprietary expansion of our existing CB-CAPs portfolio, involving a similar biochemical process
wherein complement activation products are measured on T-cells. We believe the inclusion of these markers in our AVISE Lupus test could
further amplify its sensitivity, thus facilitating earlier detection of disease, and further differentiating our test in the market.
®
®
CTD RA Sub-Profile
Approximately 70-80% of RA patients show serological evidence of RA, identified by key biomarkers: anti-CCP and Rheumatoid Factor. The
remaining 20-30% of patients, despite lacking these serological markers, are clinically diagnosed with RA; this subgroup is referred to as
“seronegative RA.” These patients often face delays in diagnosis due to the absence of serological evidence. In cases of early inflammatory
arthritis, differential diagnosis is broad, including conditions like reactive arthritis, crystal arthropathy, spondyloarthropathy, and other systemic
rheumatic diseases such as SLE and Sjogren’s syndrome, alongside seronegative RA. Accordingly, identifying unique biomarkers specific to
seronegative RA may bridge this diagnostic gap, enabling more timely and targeted treatment plans for these patients.
Lupus Nephritis Biomarkers
Lupus nephritis (LN) is an autoimmune disease and a frequent complication in people who have SLE. It causes the immune system to
produce proteins called autoantibodies that attack the body's own tissues and organs, including the kidneys. If left untreated, LN can lead to
significant health problems, permanent kidney damage and even death. Early diagnosis and treatment are key to managing LN and to
preventing it from escalating. Although early onset of LN is not typically noticeable by patients, nearly 40% of SLE patients go on to develop
LN. Currently, urinary protein to creatine ratio measurement is the standard means of assessing kidney involvement; however, it is not
necessarily indicative of kidney prognosis or treatment response. We aim to leverage intellectual property licensed from Johns Hopkins
University (JHU) to develop a test for detecting protein analytes in urine that can aid rheumatologists in the ongoing management and risk
stratification of patients suffering from LN.
AVISE SLE Monitor (2.0)
®
SLE is characterized by a chronic, systemic inflammatory burden, and disease progression is defined by the accumulation of irreversible
organ damage typically resulting from chronic inflammation and/or chronic corticosteroid use. Among the challenges for rheumatologists
responsible for the care of lupus patients is the unpredictability of the disease course defined by periods of waxing and waning episodes of
inflammation. The unpredictable nature of SLE and the lack of reliable conventional biomarkers indicative of present and near-term disease
activity results in a significant unmet need for a surrogate method to monitor disease activity. Our goal is to leverage clinical and laboratory
data collected across multiple longitudinal SLE cohorts to identify a set of biomarkers that can inform an AI-developed algorithm aimed at
guiding ongoing treatment decisions throughout the course of a lupus patient’s journey.
Sales and Marketing
We employ a specialized sales force focused on targeting the approximately 4,500 rheumatologists across the United States. Our sales
representatives generally have extensive experience in healthcare sales with backgrounds
11
in rheumatology, diagnostics and/or pharmaceutical sales. In addition, our sales representatives complete a comprehensive disease-level
sales training program and are required to participate in regular, ongoing training activities and certifications. Our goal is for our sales
representative to be viewed as a collaborative resource to the rheumatologists and their practice.
Our field-based sales force is organized into 40 territories within the following four regions: West, Central, Northeast and Southeast. We also
maintain an inside sales force that helps further our access to rheumatologists located in rural and outlying areas of the United States and
works to increase our brand awareness with healthcare providers in these areas. We continually evaluate our sales force's reach and
frequency of interactions with rheumatologists, including as we launch our pipeline products. Our specialized sales force and marketing
activities are further augmented by our centralized, dedicated client services department. Our client services department uses its high level of
technical training to enhance sales efficiency and customer satisfaction by providing personalized customer support.
Adoption and Growth through Quality Testing and Service
®
®
Our focus on quality allows for a dedicated sales approach based on a commitment to understanding the needs of both provider and patient.
By raising awareness of the benefits AVISE testing provides, our sales team is able to deliver quality testing and support services to
providers, and ultimately, their patients. To ensure our marketing and sales efforts are reaching those that we believe could benefit most from
AVISE , we emphasize execution in three core areas: targeting, messaging and call frequency. We strategically target the highest-potential
practices by utilizing various data sources (e.g., market analytics, demographic data, historical therapeutic usage and diagnostic product
trends). Furthermore, we believe the increased access afforded by our testing products will allow for patient-focused messaging and the
increased accuracy of our testing products over current standard of care diagnostic methodologies. Finally, we execute a high-frequency
promotional strategy for our top-targeted rheumatologists and their office personnel to build knowledge, understanding and retention of the
benefits of our testing products.
®
We plan to leverage core channels for building awareness and adoption, including our participation with multiple patient advocacy
organizations and medical societies, such as the American College of Rheumatology (ACR). We have also established strong relationships
with multiple rheumatology care management organizations (Super Groups), which can be key in influencing favorable reimbursement. Our
AVISE MTX testing product has been included in the clinical guidelines for two of these groups. We believe our experience with advancing a
testing product from initial development through clinical adoption differentiates us and uniquely positions us to replicate success with our
other testing products. Beyond working with these Super Groups, we intend to continue to augment field selling activity with a balanced
marketing mix, including print and digital advertising, direct marketing, continuing medical education programs and working with key opinion
leaders to support peer-to-peer educational events.
Reimbursement, Clinical Validation and Clinical Utility
Reimbursement
The primary source of revenue for our products is reimbursement from third-party payors and client bill arrangements. Third-party payors
include government payors (such as Medicare and Medicaid) and commercial payors (such as insurance companies). Achieving and
maintaining broad coverage and reimbursement from third-party payors, including Medicare, for our commercialized and pipeline products is
a key determinant of our revenue, financial results and future growth.
We are actively engaged in efforts to achieve broad commercial coverage and reimbursement for our current and future products, including
contracting with commercial payors. Achieving positive coverage reduces the need for appeals and reduces failures to collect from the
patient’s insurance. Additionally, achieving in-network contracts with commercial payors can shorten the time required to receive payments.
Our approach to commercial payment is centered on working toward inclusion in clinical guidelines and individual payor medical policies. We
seek to accomplish this through continued evidence development and publication, medical director engagement and individual claim-based
appeal efforts, detailed as follows:
▪ Meet the evidence standards necessary to be consistent with leading clinical guidelines. We believe inclusion in leading clinical
guidelines plays a critical role in payors’ coverage decisions. In order to change clinical guidelines, tests must carry a high level of
published evidence demonstrating analytical validity, clinical validity, clinical utility and cost-effectiveness. When studies with such
evidence are published in peer-reviewed journals, the authors of clinical guidelines may assess the level of evidence and determine
whether modifying existing guidelines to include new technology is warranted.
12
▪
Execute an internal managed care policy and claims adjudication function as part of our core business operations. We employ a
team of in-house claims processing and reimbursement specialists who work with patients and payors to obtain maximum
reimbursement. In parallel, a managed care team collaborates with our reimbursement specialists to ensure our payor outreach
strategy reacts to and anticipates the changing needs of our customer base. Overall, we work to address payors at the national level
in addition to high-claim-volume regional payors we have identified based on our current territory coverage.
▪ Cultivate a network of key opinion leaders. Key opinion leaders are able to influence clinical practice by publishing research and
determining whether new tests should be integrated into clinical guidelines. We collaborate with key opinion leaders early in the
development process to ensure our clinical studies are designed and executed in a way that clearly demonstrates the benefits of our
testing products to healthcare providers and payors.
While we have contracts for reimbursement with a limited number of commercial payors, we are actively pursuing additional commercial
payor contracts. When we contract to serve as a participating provider, reimbursements are made pursuant to a percentage of our charges or
a negotiated fee schedule amount. For in-network and out-of-network claims for which we are not reimbursed in full (or receive a claim
denial), we may elect to appeal the insurer’s underpayment (or denial of payment) or seek payment from the patient.
Clinical Validation
We demonstrated the clinical validity of AVISE Lupus in a study of 794 patients conducted from 2010 to 2014 across multiple leading
academic centers. The primary endpoint of the study was the specificity and sensitivity of AVISE Lupus compared to common
®
autoantibodies used to diagnose SLE and other CTDs, such as ANA and anti-dsDNA. The final results of this study showed that AVISE
Lupus demonstrated 86% specificity and 80% sensitivity in distinguishing SLE from other CTDs and fibromyalgia. Additionally, the results
showed that AVISE Lupus was 33% more specific than ANA (53% specificity/89% sensitivity) and 48% more sensitive than anti-dsDNA
(32% sensitivity/97% specificity).
®
®
®
We further demonstrated the clinical validity of AVISE Lupus for detection of probable SLE (pSLE) in a 246 subject, multi-center,
prospective, cross-sectional study, first published in the Arthritis & Rheumatology Journal in September 2019. The objective of this study was
to evaluate the frequency of AVISE Lupus and CB-CAPs as a marker of complement activation in patients with pSLE and the usefulness of
the AVISE Lupus test as a predictor of the evolution of pSLE into classified SLE by the ACR criteria. Of the 92 pSLE patients, more pSLE
were positive for CB-CAPs (28%) or AVISE Lupus (40%) than for low complement (9%) at the enrollment visit (p=0.0001, for each) and an
AVISE Lupus index score >0.08 prospectively associated with the development from pSLE to SLE by ACR classification criteria within 18
months (hazard ratio = 3.11, p<0.01).
®
®
®
®
®
Clinical Utility
We have collaborated with both academic and community clinicians to demonstrate the clinical utility of AVISE Lupus versus standard
diagnostic tests in physician diagnosis, impact on patient management decisions, patient reported outcomes and health economics.
®
®
We sponsored a longitudinal, case-control, retrospective review of medical charts in 2016 to assess the value and clinical utility of AVISE
Lupus to rheumatologists. The results of this study were published in the Open Rheumatology Journal in 2016 and suggested that a positive
AVISE Lupus test aids in the diagnosis of SLE versus standard diagnostic tests.
®
In early 2018, we initiated CARE for Lupus, a prospective, randomized, multi-site study to assess the performance of AVISE Lupus versus
standard diagnostic laboratory tests (SDLT). A total of 145 patients were enrolled across 32 sites between July 2017 and December 2018,
with 73 patients enrolled in the SDLT group and 72 patients in the AVISE Lupus group. The CARE study was published in September 2019
in Lupus Science & Medicine. Results among patients who tested positive for AVISE Lupus (n=9) showed 44% in the AVISE Lupus group
had a higher likelihood of SLE, compared with 9% in the SDLT group (p=0.127). Among patients who tested negative for AVISE Lupus
(n=63), 60% in the AVISE Lupus group had a lower likelihood of SLE, compared with 37% in the SDLT group (p=0.012). In the group of
patients randomized to the AVISE Lupus group, positive test results associated significantly with initiation of prednisone (p=0.03) and a
similar trend was observed with HCQ therapy (p=0.11). Finally, in the group of patients randomized to the AVISE Lupus group, a positive
test result associated with an increase in patient-reported outcomes measuring health-related quality of life using five-level EQ-5D (EQ5D-5L
index score) from enrollment to visit 2 (p=0.028), and greater improvements were detectable when compared to the group of patients positive
for AVISE Lupus and randomized to the SDLT arm (p=0.049).

In July 2021, a real-world retrospective analysis of patients tested with the AVISE Lupus test was published in the journal Lupus Science &
Medicine, titled "A multianalyte assay panel with cell-bound complement activation products demonstrates clinical utility in systemic lupus
®
erythematosus clinical utility study summary." A cohort of 161 AVISE Lupus tested patients from 12 rheumatology centers across the United
States provided clinical outcome data on diagnosis and treatment decisions following AVISE Lupus testing. The study findings revealed a 7
to 15-fold increased risk of Lupus diagnosis in AVISE Lupus Positive and anti-dsDNA negative patients relative to patients negative for both
tests. In addition, AVISE Lupus positive and anti-dsDNA negative patients were at 3 to 4-fold increased odds, relative to patients testing
negative for both tests, of starting a new hydroxychloroquine (cornerstone therapy for Lupus) prescription following AVISE Lupus testing.
Collectively, the study results affirm earlier study findings demonstrating the superior clinical utility and actionability of AVISE Lupus vs.
standard diagnostic testing for the differential diagnosis of Lupus.
®
®
®
®
®
®
®
In July 2022, we announced new, real-world evidence illustrating that AVISE testing can enable decisive clinical action in the differential
diagnosis of lupus. The "Complement Activation Products vs Standard ANA Testing: Treatment Outcomes, Diagnosis, and Economic Impact
in Systemic Lupus Erythematosus" (CAPSTONE) study was the largest comparative utility study in lupus diagnostics and was published in
the Journal of Managed Care & Specialty Pharmacy. The study leveraged multiple databases encompassing electronic health records and
linked insurance claims data on nearly 50,000 patients tested with AVISE or standard of care labs from hundreds of rheumatologists across
the United States, comparing diagnosis, treatment and cost of care outcomes for new patients tested with AVISE Lupus and those tested
with a traditional ANA (tANA) approach, including specific autoantibodies. The CAPSTONE study supports that the AVISE Lupus test is
more clinically effective, both for patients who test positive and those who test negative, as compared to the current standard of care.
Important key findings of the CAPSTONE study included, among other things, a: (i) 2x decrease in diagnostic testing costs in the first six-
month follow-up period for AVISE Lupus [-] vs. tANA[-]; (ii) 3.5x less frequent repeat testing overall when using AVISE Lupus vs. tANA; (iii)
®
6x increased odds of establishing a new SLE diagnosis with AVISE Lupus [+] vs. tANA[+]; and (iv) 3x increased odds of initiating one or
more SLE treatments with AVISE Lupus [+] vs. tANA[+]. The CAPSTONE study exemplifies the advantages of the AVISE Lupus test for
patients, providers and payors. Delayed diagnosis leads to increased disease burden and diminished quality of life for the patient relative to
the current standard of care. By receiving conclusive results, providers are able to initiate treatment early, reducing the need for more
aggressive approaches down the road that can lead to irreversible consequences for the patient. Additionally, a conclusive negative test
allows providers to lower the number of repeat tests and follow-up visits which is a critical step for achieving diagnostic clarity for the patient.

Healthcare Economics
In October 2020, a study in collaboration with leading health economic experts was published in the journal ACR Open Rheumatology, titled
"Evaluation of the Economic Benefit of Earlier SLE Diagnosis using a Multivariate Assay Panel (MAP)." This was the first ever evaluation of
the economics of diagnosing SLE with AVISE Lupus (MAP) compared to standard diagnostic laboratory tests in a hypothetical cohort of
1,000 suspected SLE patients. Over the four-year time horizon, AVISE Lupus demonstrated an estimated total direct cost savings of
approximately $2.0 million ($1,991 per patient). In addition, the study findings from the economic model estimated a $0.7 million dollar
savings in total cost of care with AVISE Lupus versus a conventional SLE biomarker testing approach, as a result of the increased
diagnostic sensitivity of the AVISE Lupus test leading to fewer in-patient hospitalization costs. On a per tested basis, the AVISE Lupus test
is estimated to reduce total cost of care by $655 per eligible patient in the first year.

Laboratory Operations
®
We perform all of our AVISE tests in our approximately 13,000 square-foot laboratory located in Vista, California. Our laboratory is certified
under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) and accredited by the College of American Pathologists (CAP). Our
laboratory is certified for performance of high-complexity testing by the Centers for Medicare & Medicaid Services (CMS) in accordance with
CLIA and is licensed by California and all states requiring out-of-state licensure, including the New York State Department of Health
(NYSDOH). Our clinical laboratory typically reports AVISE testing product results within five business days.
®
We believe that our existing laboratory facility is adequate to meet our business needs for at least the next 12 months and that additional
laboratory space will be available on commercially reasonable terms, if required.
Quality Assurance
Our quality assurance function oversees the quality of our laboratory operations. We have established oversight for systems implementation
and maintenance procedures, document control processes, supplier qualification,
14
preventive or corrective actions and employee training processes that we believe achieves excellence in operations. We continuously
monitor and improve our processes and procedures and believe this high-quality service leads to customer satisfaction and retention.
Competition
The traditional methods used by healthcare providers to test patients with CTD-like symptoms are the main competitors of our AVISE testing
products. Such traditional methods include testing for a broad range of diagnostic, immunology and chemistry biomarkers, such as ANA and
anti-dsDNA, and serum complement biomarkers, such as C3 and C4. We also face competition from commercial laboratories, such as
Laboratory Corporation of America Holdings, Quest Diagnostics Incorporated, ARUP Laboratories, Inc. and the Mayo Clinic, all of which have
existing infrastructures to support the commercialization of diagnostic services. Large, multispecialty group medical clinics, health systems
and academic medical university-based clinics may provide in-house clinical laboratories offering autoimmune and autoimmune-related
disease testing services. Additionally, we compete against regional clinical laboratories providing testing in the autoimmune and autoimmune-
related disease field, including Rheumatology Diagnostics Laboratories, Inc. (acquired by Laboratory Corporation of America in June 2020).
Other potential competitors include companies that might develop diagnostic, disease or drug monitoring products, such as Progentec
Diagnostics Inc., Scipher Medicine Corporation, Genalyte Inc., Oncimmune plc, DxTerity Diagnostics Inc., AMPEL BioSolutions, and
Immunovia AB. In the future, we may also face competition from companies developing new products or technologies.
®
We believe the principal competitive factors in our target market include: quality and strength of clinical and analytical validation data;
confidence in diagnostic results; sales and marketing capabilities; the extent of reimbursement; inclusion in clinical guidelines; cost-
effectiveness; and ease of use. We rely upon independent sources for phlebotomy to obtain patient samples; interruptions to this capability
could dramatically impact patient access to our tests.
Many of our potential competitors have widespread brand recognition and substantially greater financial, technical and research and
development resources; in addition to greater selling and marketing capabilities. Others may develop products with prices lower than ours or
have preferred network status that could be viewed by rheumatologists and payors as functionally equivalent to our solution or offer solutions
at prices designed to promote market penetration. This could force us to lower the list price of our products and affect our ability to achieve
profitability. If we are unable to change clinical practice in a meaningful way or compete successfully against current and future competitors,
we may be unable to increase market acceptance and sales of our products, which could prevent us from increasing our revenue or
achieving profitability.

License Agreements
Amended and Restated Exclusive License Agreement with the University of Pittsburgh
In August 2011, we entered into an amended and restated exclusive license agreement with UPitt, to amend and restate the exclusive
license agreement we obtained by our purchase of the medical diagnostics division of Cypress Bioscience, Inc. (Cypress) in 2010 (the
Cypress Purchase) and to obtain an exclusive license to UPitt’s patent rights in certain inventions (the UPitt Patent Rights) related to the use
of CB-CAPs technology in the diagnosis, prognosis and monitoring of diseases, including certain patents related to our AVISE testing
products.
®
Under the agreement, we are permitted to make, use and sell products and services utilizing the UPitt Patent Rights in the field of SLE and
the field of monitoring of organ transplantation and organ rejection and to sublicense such rights. UPitt retained the right to practice under the
UPitt Patent Rights and to use such rights for non-commercial education and research purposes. In addition, this agreement is subject to the
rights of the U.S. government, if any, as set forth in 35 U.S.C. §200, et seq. Pursuant to this law, the U.S. government may have acquired a
nonexclusive, nontransferable, paid-up license to practice or have practiced for or on behalf of the U.S. government the inventions described

March 23, 2024, which is the date of the expiration of the last licensed patent covering the applicable licensed product or service.
Exclusive License Agreement and Master Research Collaboration Agreement with Allegheny Health Network Research Institute
In May 2021, we entered into an exclusive license agreement with AHN, under which we obtained an exclusive, worldwide license to AHN's
patent rights in certain inventions (the AHN Patent Rights) related to diagnostics for autoimmune rheumatic diseases.
Under the agreement, we are permitted to make, use and sell products and services utilizing the AHN Patent Rights and to sublicense such
rights; provided, however, that any such sublicenses may only be granted with AHN's consent. AHN retained the right to practice under the
AHN Patent Rights and to use such rights for teaching, research, education, public service, clinical and other research-related purposes. In
addition, the agreement is subject to the rights of the U.S. government with respect to the AHN Patent Rights, including under a funding
agreement between AHN and the U.S. government and under the Bayh-Dole Act (35 U.S.C. §200, et seq.). Pursuant to the Bayh-Dole Act,
the U.S. government may acquire a nonexclusive, nontransferable, paid-up license to practice or have practiced for or on behalf of the U.S.
government the inventions described in the AHN Patent Rights throughout the world.
In consideration for the rights granted to us under the agreement, we paid an initial license fee to AHN to cover past patent expenses and
agreed to pay future direct patent costs related to AHN Patent Rights. We are also required to pay AHN a low single-digit royalty on net sales
of products utilizing the AHN Patent Rights through the first quarter of 2024 sold by us or our affiliates, subject to adjustment in certain
circumstances. Beginning in the second quarter of 2024, we are required to pay AHN an increased low single-digit royalty or a flat annual
minimum royalty amount, which royalty obligations continue for each licensed product on a country-by-country basis until the expiration of the
last licensed patent covering the applicable licensed product in such country, pending approvals and commercialization, or the earlier
termination of the agreement (excluding payment obligations accruing prior to such termination).
In the event we sublicense any of the AHN Patent Rights, we are obligated to pay AHN a mid-double-digit percentage of any sublicense
income, whether in the form of royalties or sub-license fees.
The agreement requires that we diligently develop and commercialize products that are covered by the AHN Patent Rights. If we elect not to
pursue intellectual property rights or expand commercialization to certain territories within a commercially reasonable period, AHN may
pursue other licenses and terminate our exclusive license with respect to such territories upon 30 days prior written notice.
We may terminate the agreement upon 60-day written notice to AHN provided we pay a specified termination fee. AHN may terminate the
agreement in the event of our nonperformance of any of our material obligations under the agreement if such nonperformance remains
uncured for a certain period of time following our receipt of written notice of such nonperformance or in the event of insolvency. Absent early
termination, the agreement will continue until expiration date of the longest-lived patent right included in the AHN Patent Rights.
In addition, we entered into a master research collaboration agreement with AHN, focused on the development of novel patented biomarkers
for diagnosis, prognosis and monitoring of autoimmune diseases, including SLE. The agreement has a three-year initial term, expiring May
2024, with renewals thereafter for successive one-year terms upon mutual agreement with AHN. Each party may terminate the agreement
upon 60 days' notice to the other party. We are required to pay AHN a collaboration fee of $0.4 million for each year of the agreement and
AHN is required to make an in-kind contribution equivalent of $0.3 million for the initial term and each subsequent one-year term, if any.
Exclusive License Agreement and Collaboration Agreement with Queen Mary University of London
In November 2021, we entered into an exclusive license agreement with Queen Mary University of London (QMUL), under which we
obtained an exclusive license to QMUL's patent-pending inventions (the QMUL Patent Rights), related to diagnosis and/or development of
diagnostic or companion diagnostics for RA.
Under the agreement, we are permitted to make, use and sell products and services utilizing the QMUL Patent Rights and to sublicense such
rights; provided, however, that any such sublicenses may only be granted with QMUL's consent. QMUL retained the right to practice under
the QMUL Patent Rights and to use such rights for teaching, research, education, public service, clinical and other research-related
purposes.
17
In consideration for the rights granted to us under the agreement, we paid an initial license fee to QMUL and payment of past patent
expenses and ongoing patent expenses. We are required to make a $0.1 million milestone payment upon the first commercial sale of
products utilizing the QMUL Patent Rights. In addition, after the first 18 months of commercial sales under the terms of the exclusive license
agreement, we are required to pay royalties in the low to high single-digits on net sales of testing products using the assigned patents,
pending approvals and commercialization.
In the event we sublicense any of the QMUL Patent Rights, we are obligated to pay QMUL a double-digit percentage of sublicensing income,
whether in the form of royalties or sub-license fees.
The agreement requires that we diligently develop and commercialize products that are covered by the QMUL Patent Rights. QMUL may
terminate the agreement if we fail to develop the QMUL Patent Rights in the field of diagnosis and/or development of diagnostic or
companion diagnostics for rheumatoid arthritis, QMUL may convert our license to non-exclusive.
In April 2023, we discontinued development of our AVISE RADR platform, which was being developed using the QMUL Patent Rights. We
also discontinued the associated clinical trials. We are permitted to terminate the license agreement upon six month written notice to QMUL.
QMUL may terminate the agreement in the event of our nonperformance of any of our material obligations under the agreement if such
nonperformance remains uncured for a certain period of time following our receipt of written notice of such nonperformance or in the event of
insolvency. Absent early termination, the agreement will continue for a period of 20 years after the first commercial sale of any licensed
product utilizing the QMUL Patent Rights.
®
In addition, we entered into a collaboration agreement with QMUL for a three-year term, expiring November 2024. We or QMUL may
terminate the master research collaboration agreement upon 30-day written notice.
Exclusive License Agreement Johns Hopkins University
In November 2023, we entered into an exclusive license agreement with Johns Hopkins University, under which we obtained an exclusive,
worldwide license to JHU’s patent rights in certain inventions (the JHU Patent Rights) related to methods of using urinary protein biomarkers
as a means of risk stratifying lupus nephritis patients and predicting treatment response.
Under the agreement, we are permitted to make, use, import, export, offer and sell products and services utilizing the JHU Patent Rights and
to sublicense such rights, subject to certain limitations. JHU retained the right to practice under the JHU Patent Rights and to use such rights
for teaching, research, education, public service, clinical and other research related purposes; in addition to make, use and sell products and
services to a qualified humanitarian organization for humanitarian purposes in so-called “least developed countries,” as defined by the United
Nations Country Classification.
In consideration for the rights granted to us under the agreement, we paid an initial license fee and past patent expenses and agreed to pay
future direct patent costs related to the JHU Patent Rights. Under the terms of the exclusive license agreement, we are required to pay
royalties in the low single-digits on net sales of products using the assigned patents, subject to annual minimums, as well as certain
milestone payments.
In the event we sublicense any of the JHU Patent Rights, we are obligated to pay JHU a double-digit percentage of sublicensing income;
however, royalties we receive on sales made by sublicensees will be treated as if we made the sale.
The agreement requires that we diligently develop and commercialize products that are covered by the JHU Patent Rights, and we have
agreed to meet certain development and commercial milestones. JHU may terminate the agreement if we fail to develop, commercialize and
sell the licensed products. Additionally, JHU may terminate the agreement for cause upon 60-day written notice in the event of our
nonperformance of any of our material obligations under the agreement if such nonperformance remains uncured for a certain period of time
following our receipt of written notice of such nonperformance or in the event of insolvency. JHU may terminate the agreement immediately
upon written notice to Exagen in the event of a material breach that is incapable of cure. Absent early termination, the agreement will
continue for the longer of (i) expiration of the last to expire patent included in the license agreement, (ii) 10 years after the first commercial
sale of any licensed product utilizing the JHU Patent Rights, or (iii) if no patents issue, 20 years from the effective date of the agreement
(November 8, 2023). We may terminate the agreement upon ninety days’ advance written notice to JHU.
Regulations
18
Clinical Laboratory Improvement Amendments of 1988
As a clinical laboratory, we are required to hold certain federal, state and local licenses, certifications and permits to conduct our business.
Under CLIA, we are required to hold a certificate applicable to the categories of laboratory tests we perform and to comply with standards
applicable to our operations, including test processes, personnel, facilities administration, equipment maintenance, recordkeeping, quality
systems and proficiency testing. We must maintain CLIA certification to be eligible to bill for diagnostic services provided to Medicare
beneficiaries. Many commercial third-party payors also require CLIA certification as a condition of payment.
Our Vista facility holds a current CLIA certificate. To renew our CLIA certificate, we are subject to survey and inspection every two years to
assess compliance with program standards. We elect to participate in the accreditation program of CAP. CMS has deemed CAP standards to
be equally or more stringent than CLIA regulations and has approved CAP as a recognized accrediting organization. Inspection by CAP is
performed in lieu of inspection by CMS for CAP-accredited laboratories. Because we are accredited by the CAP Laboratory Accreditation
Program, we are deemed to also comply with CLIA. The regulatory and compliance standards applicable to the testing we perform may
change over time, and any such changes could have a material effect on our business.
Penalties for non-compliance with CLIA or CAP requirements include suspension, limitation or revocation of the laboratory’s CLIA or CAP
certificate, as well as a directed plan of correction, state on-site monitoring, civil money penalties, civil injunctive suit or criminal penalties, as
applicable.
State Laboratory Licensing
Our Vista facility also holds a state license issued by the California Department of Public Health (DPH). California law and regulations
establish standards for the day-to-day operation of a clinical laboratory, including the training and skills required of laboratory personnel and
quality control. In addition, California laws and regulations also mandate proficiency testing, which involves testing of specimens that have
been specifically prepared for the laboratory for quality control purposes.
Because we receive specimens from New York, our Vista facility is also required to be licensed by the NYSDOH New York laws and
regulations establish standards in a variety of operational areas, including:
▪
▪
▪
▪
day-to-day operation of the laboratory, including training, supervision and skill levels required of laboratory personnel;
physical requirements of a facility;
equipment; and
validation and quality control.
New York law also mandates proficiency testing for laboratories licensed under New York state law, regardless of whether such laboratories
are located in or outside of New York. If a laboratory is out of compliance with New York's statutory or regulatory standards, the NYSDOH,
may suspend, limit, revoke or annul the laboratory’s New York license, censure the holder of the license or assess civil money penalties.
Statutory or regulatory noncompliance may result in a laboratory’s operator being found guilty of a misdemeanor under New York law. New
York's law and regulations are more stringent than CLIA in certain respects. For example, NYSDOH must approve a laboratory developed
test (LDT) before it is offered in New York. We have received written approval from NYSDOH to offer our products in New York.
In addition to New York and California, other states, including Maryland, Pennsylvania and Rhode Island, require licensing of out-of-state
laboratories under certain circumstances.
Federal Oversight of Laboratory Developed Tests and Certain Devices
The laws and regulations governing the marketing of diagnostic products are evolving, extremely complex, and in many instances, there are
no significant regulatory or judicial interpretations of these laws and regulations. We perform our tests like AVISE CTD, AVISE SLE
Prognostic and AVISE MTX assays in our Vista, California clinical laboratory, and they are currently primarily regulated under CLIA, as
administered by CMS, as well as by applicable state laws, as described above. The FDA regulates any diagnostic tests that meet the
definition of a medical device, except under specific, narrow circumstances. The Federal Food, Drug and Cosmetic Act (FDCA) defines a
medical device as "an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article,
including a component part, or accessory, which is, among other things: intended for use in the
®
®
®
19
diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or other animals and which
does not achieve its primary intended purposes through chemical action within or on the body of man or other animals and which is not
dependent upon being metabolized for the achievement of any of its primary intended purposes." By this definition, in vitro reagents and
diagnostic tests are considered medical devices. Specifically, the FDA defines an in vitro diagnostic test (IVD) as "reagents, instruments, and
systems intended for use in the diagnosis of disease or other conditions, including a determination of the state of health, in order to cure,
mitigate, treat, or prevent disease or its sequelae." Therefore, the FDA generally considers diagnostic testing products like ours to be IVDs
subject to the agency's regulatory requirements.
Among other things, pursuant to the FDCA and its implementing regulations, the FDA regulates the research, testing, manufacturing, safety,
labeling, storage, recordkeeping, pre-market clearance or approval, marketing and promotion and sales and distribution of medical devices,
including IVDs, in the United States to ensure that medical products distributed domestically are safe and effective for their intended uses. In
addition, the FDA regulates the export of medical devices manufactured in the United States to international markets. Many of the
instruments, reagents, kits or other consumable products used within our laboratories are regulated as medical devices and therefore must
comply with FDA quality system regulations and certain other device requirements. We have policies and procedures in place to ensure that
we source such materials from suppliers that are in compliance with any applicable medical device regulatory requirements.
The FDCA 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. Devices deemed by the FDA to pose the greatest risk, such as life-
sustaining, life-supporting or implantable devices or devices deemed not substantially equivalent to a previously 510(k) cleared device, are
categorized as Class III. These devices typically require submission and approval of a premarket approval application (PMA). Devices
deemed to pose lower risk are categorized as either Class I or II. For most Class II devices, a manufacturer must submit to the FDA a 510(k)
premarket notification submission requesting clearance of the device for commercial distribution in the United States. Some low-risk Class II
devices are exempted from this requirement. When a 510(k) premarket notification submission is required, the manufacturer must submit to
the FDA a premarket notification submission demonstrating that the device is "substantially equivalent" to a predicate device, which is: (i) a
device that was legally marketed prior to May 28, 1976, for which PMA approval is not required, (ii) a legally marketed device that has been
reclassified from Class III to Class II or Class I, or (iii) another legally marketed, similar device that has been cleared through the 510(k)
clearance process. Class II devices may also be subject to special controls such as performance standards, post-market surveillance, FDA
guidelines, or particularized labeling. Most Class I devices are exempt from 510(k) premarket notification requirements, but like Class II and
Class III devices, are subject to general controls, such as registration and listing, quality system, labeling, and reporting requirements.
After the FDA permits a device to enter commercial distribution, numerous regulatory requirements apply. These include: the Quality System
Regulation, which requires manufacturers to follow elaborate design, testing, control, documentation and other quality assurance procedures
during the manufacturing process; labeling regulations; the FDA’s general prohibition against promoting products for unapproved or "off-label"
uses; and 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 the
malfunction were to recur. The FDA has broad post-market and regulatory and enforcement powers. Failure to comply with the applicable
U.S. medical device regulatory requirements could result in, among other things, warning letters, fines, injunctions, consent decrees, civil
penalties, repairs, replacements, refunds, recalls or seizures of products, total or partial suspension of production, the FDA’s refusal to grant
future premarket clearances or approvals, withdrawals or suspensions of current product applications, and criminal prosecution.
Although the FDA has statutory authority to assure that medical devices, including IVDs, are safe and effective for their intended uses, the
FDA has generally exercised its enforcement discretion and not enforced applicable device regulations with respect to IVDs that are
designed, manufactured and used within a single high-complexity CLIA-certified laboratory for use only in that laboratory. Such tests are
referred to as LDTs. We believe that all of our AVISE test products are LDTs, as are our near-term pipeline candidate tests. However, in
October 2023, the FDA issued a proposed rule aimed at regulating LDTs under the current medical device framework and proposing to
phase out its existing enforcement discretion policy for this category of diagnostic tests; the public comment period ended in early December
2023. The proposal envisions that the LDT enforcement policy phase-out process would occur in gradual stages over a total period of four
years, with pre-market approval applications for high-risk tests to be submitted by the 3.5-year mark, although more details are expected to
be provided with the upcoming final rule. The likelihood of the FDA finalizing the proposed rule in April 2024 (as is currently projected), as
well as potential litigation challenging the agency’s authority to take such action, is uncertain at this time. Affected stakeholders continue to
press for a comprehensive legislative solution to create a harmonized paradigm for oversight of LDTs by
®
20
both the FDA and CMS, instead of implementation of the proposed FDA administrative action, which may be disruptive to the industry and to
patient access to certain diagnostic tests.
Even though we presently commercialize our tests as LDTs, the FDA may disagree that our marketed tests are within the scope of its current
enforcement discretion criteria for LDTs, our tests may in the future become subject to more onerous regulation by the FDA. For several
years, members of Congress have been working with stakeholders on a possible bill to regulate in vitro clinical tests including LDTs. For
example, as drafted and re-introduced for consideration by the current Congress, legislation called the Verifying Accurate, Leading-edge
IVCT Development (VALID Act), has been garnering bipartisan and bicameral support. The VALID Act would codify into law the term "in vitro
clinical test" (IVCT) to create a new medical product category separate from medical devices that includes products currently regulated as
IVDs as well as LDTs. The VALID Act would also create a new system for labs and hospitals to use to submit their tests electronically to the
FDA for approval, which is aimed at reducing the amount of time it takes for the agency to approve such tests, and establish a new program
to expedite the development of diagnostic tests that can be used to address a current unmet need for patients.
It is unclear whether the VALID Act would be passed by Congress in its current form or signed into law by the President. If the FDA finalizes
its position on regulation of LDTs through the ongoing notice-and-comment rulemaking process, or the VALID Act or other federal legislation
is passed reforming the government’s regulation of LDTs, or alternatively, if the FDA disagrees with our assessment that our tests fall within
the definition of an LDT, we could, for the first time, be subject to enforcement of regulatory requirements such as registration and listing
requirements, medical device reporting requirements and quality control requirements. Any new legislation or FDA regulations affecting LDTs
may result in increased regulatory burdens on our ability to continue marketing our tests and to develop and introduce new tests in the future.
Additionally, if and when the FDA begins to actively enforce its premarket submission regulations with respect to LDTs generally or our tests
in particular, whether as a result of new legislative authority or culmination of the current notice-and-comment rulemaking process, we may
be required to obtain premarket clearance for our tests under Section 510(k) of the FDCA or approval of a PMA. The process for submitting a
510(k) premarket notification and receiving FDA clearance usually takes from three to 12 months, but it can take significantly longer and
clearance is never guaranteed. The process for submitting and obtaining FDA approval of a PMA generally takes from one to three years or
even longer and approval is not guaranteed. PMA approval typically requires extensive clinical data and can be significantly longer, more
expensive and more uncertain than the 510(k) clearance process. If premarket review is required for some or all of our tests, the FDA could
require that we stop selling our products pending clearance or approval and conduct clinical testing prior to making submissions to the FDA
to obtain premarket clearance or approval. The FDA could also require that we label our tests as investigational or limit the labeling claims
we are permitted to make.
Regulation of Clinical Trials
We have also conducted and may in the future conduct research studies for our AVISE tests and our other tests in development that involve
clinical investigators and human subjects (or stored specimens from human subjects) at sites in the United States. We may need to conduct
additional clinical trials for the AVISE tests, as well as other tests we may offer in the future, to drive test adoption in the marketplace and
reimbursement. Should we not be able to perform these studies, or should their results not provide clinically meaningful data and value for
clinicians, adoption of our tests could be impaired and we may not be able to obtain reimbursement for them.
®
®
The conduct of clinical trials is also subject to extensive federal and institutional regulations intended to assure that the data and reported
results are credible and accurate and that the rights, safety, and welfare of study participants are protected. Most studies involving human
participants must be reviewed and approved by, and conducted under the auspices of, a duly-constituted institutional review board (IRB),
which is a multi-disciplinary committee responsible for reviewing and evaluating the risks and benefits of a clinical trial for participating
subjects and monitoring the trial on an ongoing basis. Companies sponsoring the clinical trials and investigators also must comply with, as
applicable, regulations, guidelines and IRB requirements for obtaining informed consent from the study subjects, following the protocol and
investigational plan, adequately monitoring the clinical trial, and timely reporting of adverse events. The sponsoring company or the IRB may
suspend or terminate a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an
unacceptable health risk. In addition, trials involving human subjects often require significant time and cash resources to complete and are
subject to a high degree of risk, including risks of experiencing delays, failing to complete the trial or obtaining unexpected or negative
results.
Advertising of Laboratory Services or LDTs
Advertising for laboratory services and diagnostic testing products is subject to federal truth-in-advertising laws enforced by the Federal
Trade Commission (FTC), as well as comparable state consumer protection laws, whether or not such services are regulated by the FDA as
Class I or Class II devices or not directly subject to enforcement
21
discretion with respect to the FDA’s device requirements as LDTs. Under the Federal Trade Commission Act (FTC Act), the FTC is
empowered, among other things, to (a) prevent unfair methods of competition and unfair or deceptive acts or practices in or affecting
commerce; (b) seek monetary redress and other relief for conduct injurious to consumers; and (c) gather and compile information and
conduct investigations relating to the organization, business, practices, and management of entities engaged in commerce. The FTC has
very broad enforcement authority, and failure to abide by the substantive requirements of the FTC Act and other consumer protection laws
can result in administrative or judicial penalties, including civil penalties, injunctions affecting the manner in which we would be able to market
services or products in the future, or criminal prosecution.
Federal and State Physician Self-Referral Prohibitions
We are subject to the federal physician self-referral prohibitions, commonly known as the Stark Law, and to similar state law restrictions, such
as California’s Physician Ownership and Referral Act of 1933 (PORA), and other comparable state laws. The Stark Law generally prohibits
us from billing Medicare or Medicaid for certain designated health services, including clinical laboratory services, when the physician ordering
the service, or any member of such physician’s immediate family, has a financial relationship with us, unless the arrangement meets an
exception to the prohibition. A financial relationship can be a compensation arrangement or an ownership or investment interest.
Sanctions for a Stark Law violation include the following:
▪
▪
▪
▪
▪
denial of payment for the services provided in violation of the prohibition;
refunds of amounts collected in violation of the Stark Law;
significant civil penalties for each bill or claim for a service arising out of the prohibited referral, and additional penalties for each
arrangement or scheme that the parties know (or should know) has the principal purpose of circumventing the Stark Law's
prohibition;
the imposition of penalties of up to three times the amounts assessed for each item or service wrongfully claimed; and
possible exclusion from federal healthcare programs, including Medicare and Medicaid.
The Stark Law applies regardless of any intent by the parties to induce or reward referrals or the reasons for the financial relationship and the
referral. In addition, violations of the Stark Law may also serve as the basis for liability under the federal False Claims Act, which can result in
additional civil penalties.
Similarly, PORA makes it unlawful for a physician or certain other healing arts licensees to refer a person for certain healthcare services,
including clinical laboratory services, if the licensee has a financial interest with the person or entity that receives the referral, unless an
exemption is met. Unlike the Stark Law, PORA applies regardless of the source of payment. PORA also prohibits the submission of claims
for services provided pursuant to a prohibited referral, and violation of this prohibition constitutes a public offense and is punishable upon
conviction by a fine not exceeding fifteen thousand dollars ($15,000) for each violation and appropriate disciplinary action. Other states also
have self-referral restrictions with which we have to comply, some of which differ from those imposed by the Stark Law or PORA.
Federal and State Anti-Kickback Laws
The Federal Anti-Kickback Statute makes it a felony for a person or entity, including a clinical laboratory, to knowingly and willfully offer, pay,
solicit or receive any remuneration, directly or indirectly, overtly or covertly, in cash or in kind, in order to induce or in return for the referral of
an individual for the furnishing of, or the recommending or arranging for the furnishing of, purchasing, leasing, ordering or arranging for or
recommending purchasing, leasing or ordering of any item or service that is reimbursable in whole or in part, under any federal healthcare
program. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a
violation. Courts have broadly interpreted the scope of the Anti-Kickback Statute and generally have held that the statute may be violated if
merely one purpose of a payment arrangement is to induce referrals.
In addition to statutory exceptions to the Anti-Kickback Statute, regulations provide for a number of safe harbors. If an arrangement meets
the provisions of a safe harbor or exception, it is deemed not to violate the Anti-Kickback Statute, and the parties are immune from
prosecution. An arrangement must fully comply with each element of an applicable safe harbor in order to qualify for protection.
22
Failure to meet the requirements of an exception or a safe harbor does not render an arrangement illegal. Rather, the government may
evaluate such arrangements on a case-by-case basis, taking into account all facts and circumstances.
A violation of the Anti-Kickback Statute may result in imprisonment for up to ten years and significant fines for each violation and additional
administrative civil money penalties, plus up to three times the amount of the remuneration paid. Convictions under the Anti-Kickback Statute
result in mandatory exclusion from federal healthcare programs for a minimum of five years. In addition, a violation of the Anti-Kickback
Statute can serve as the basis of liability under the federal False Claims Act, which is discussed in greater detail below.
Although the Anti-Kickback Statute applies only to items and services reimbursable under any federal healthcare program, a number of
states, including California, have passed statutes substantially similar to the Anti-Kickback Statute that apply to all third-party payors,
including commercial insurers, and, in some states, to patients without insurance. The California Attorney General and courts have
interpreted the California anti-kickback and fee-splitting laws in substantially the same way as the courts have interpreted the Anti-Kickback
Statute. Penalties under such state laws include imprisonment and significant monetary fines.
In addition, in October 2018, the Eliminating Kickbacks in Recovery Act of 2018 (EKRA) was enacted as part of the Substance Use-Disorder
Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act. EKRA is an all-payor anti-kickback law that
makes it a criminal offense to pay any remuneration to induce referrals to, or in exchange for, patients using the services of a recovery home,
a substance use clinical treatment facility, or laboratory. However, unlike the Anti-Kickback Statute, EKRA is not limited to services covered
by federal healthcare programs but applies more broadly to services covered by “healthcare benefit programs,” including commercial third-
party payors. Although EKRA apparently was intended to reach patient brokering and similar arrangements to induce patronage of substance
use recovery and treatment, the language in EKRA is broadly written. Further, certain of EKRA’s exceptions are inconsistent with the Anti-
Kickback Statute and regulations. EKRA permits the U.S. Department of Justice to issue regulations clarifying EKRA’s exceptions or adding
additional exceptions, but such regulations have not yet been issued.
Other Federal and State Healthcare Laws
In addition to the requirements discussed above, several other healthcare fraud and abuse laws could have an effect on our business. For
example, federal law permits the U.S. Department of Health and Human Services (HHS) Office of Inspector General (OIG), to exclude an
individual or entity from Medicare or Medicaid for charging federal healthcare programs, including Medicare or Medicaid, substantially in
excess of its usual charges for its items or services absent a finding of good cause. The terms “usual charge” and “substantially in excess”
are subject to varying interpretations, and the HHS OIG has withdrawn multiple versions of a proposed rule intended to implement the
statute.
The federal False Claims Act prohibits, among other things, a person from knowingly presenting, or causing to be presented, a false or
fraudulent claim for payment to the federal government. 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 pursuant to its qui tam provisions.
Because the complaint in a qui tam action is initially filed under seal, the action may be pending for some time before the defendant is even
aware of the action. Regardless of whether the government intervenes in the action, the relator, if successful, will receive a percentage of the
recovery. In addition, providers and suppliers must report and return any overpayments received from the Medicare and Medicaid programs
within 60 days of identification, and failure to identify and return such overpayments exposes the provider or supplier to federal False Claims
Act liability. Violation of the federal False Claims Act may result payment of up to three times the actual damages sustained by the
government, plus significant per-claim civil penalties, as well as mandatory exclusion from government healthcare programs. Several states,
including California, have enacted comparable false claims laws that may apply regardless of payor.
The federal civil monetary penalties law (the CMP Law) prohibits, among other things, (1) the offering or transfer of remuneration (including a
waiver of copayments and deductible amounts) to a Medicare or Medicaid 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 Medicaid, unless
an exception applies; (2) employing or contracting with an individual or entity that the provider knows or should know is excluded from
participation in a federal healthcare program; (3) billing for services requested by an unlicensed physician or an excluded provider; (4) billing
for medically unnecessary services; and (5) presenting or causing to be presented a claim to a federal healthcare program that the person
knows or should know is for an item or service that was not provided as claimed or is false or fraudulent. The penalties for violating the CMP
Law may include exclusion, substantial fines, and payment of up to three times the amount billed, depending on the nature of the offense.
23
As noted, a person who offers or provides to a Medicare or Medicaid beneficiary any remuneration, including waivers of co-payments, co-
insurance and deductible amounts (or any part thereof), that the person 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 may be held liable under the CMP Law.
Moreover, in certain cases, providers who routinely waive amounts owed by federal healthcare program beneficiaries can also be held liable
under the Anti-Kickback Statute and the federal False Claims Act. One of the exceptions to the prohibition under the CMP Law covers non-
routine, unadvertised waivers of copayments or deductible amounts based on individualized determinations of financial need or exhaustion of
reasonable collection efforts, and the Anti-Kickback Statute has a safe harbor. The HHS OIG, has emphasized in guidance documents that
this exception should only be used on a case-by-case basis to address the financial needs of each particular patient. Although this prohibition
applies only to federal healthcare program beneficiaries, applicable state laws related to, among other things, unlawful schemes to defraud,
excessive fees for services, tortious interference with patient contracts and statutory or common law fraud, may also be implicated for similar
practices offered to patients covered by commercial payors.
Federal criminal statutes prohibit, among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any
healthcare benefit program, including those administered by commercial payors, and 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. Like the Anti-Kickback Statute, this federal criminal statute requires a showing of intent, but a person or entity
does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.
The Physician Payments Sunshine Act imposes annual reporting requirements on manufacturers of certain devices, drugs and biologics for
certain payments and transfers of value by them and in some cases their distributors to physicians (defined to include doctors, dentists,
optometrists, podiatrists and chiropractors), certain other healthcare providers (such as nurse practitioners), and teaching hospitals, as well
as ownership and investment interests held by physicians (as defined under the statute) and their immediate family members. Any failure to
comply with these reporting requirements could result in significant fines and penalties. Because we manufacture our own in vitro diagnostic
tests solely for use by or within our own laboratory, we believe that we are exempt from these reporting requirements. We may become
subject to such reporting requirements under the terms of current CMS regulations, however, if enacted federal legislation renders our tests
regulated by FDA, or if FDA finalizes its recently initiated notice-and-comment rulemaking to exercise authority over LDTs as medical devices
or otherwise requires us to obtain premarket clearance or approval for one or more of our tests. A determination that we have violated these
laws and regulations, or a public announcement that we are being investigated for possible violations, could adversely affect our business,
prospects, results of operations or financial condition.
We are also subject to applicable state restrictions on laboratory billing. These laws vary from state to state but generally are intended to
prevent a provider who ordered but did not perform the service from billing for that service at a markup. For example, California has an anti-
markup statute with which we must comply, which prohibits a provider 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 that performed the test except for any other service actually rendered
to the patient by the provider (for example, specimen collection, processing and handling). This provision applies, with certain limited
exceptions, to licensed persons such as physicians and clinical laboratories regulated under California’s 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 and other client
billing restrictions with which we must comply. Many states also have "direct-bill" laws, which require the party that performed the service to
bill for the service, with certain exceptions.
If our operations are found to be in violation of any of the fraud and abuse laws described above or any other healthcare regulatory laws that
apply to us, we may be subject to penalties, including potentially significant criminal and civil and/or administrative penalties, damages, fines,
disgorgement, imprisonment, exclusion from participation in government healthcare programs, contractual damages, reputational harm,
administrative burdens, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could
adversely affect our ability to operate our business and our results of operations.
International Regulations
Many countries in which we may offer any of our testing products in the future have anti-kickback regulations prohibiting providers from
offering, paying, soliciting or receiving remuneration, directly or indirectly, in order to induce business that is reimbursable under any national
healthcare program. In situations involving physicians employed by state-funded institutions or national healthcare agencies, violation of the
local anti-kickback law may
24
also constitute a violation of the U.S. Foreign Corrupt Practices Act (FCPA), and/or other applicable anti-corruption laws.
The FCPA prohibits any U.S. individual, business entity or employee of a U.S. business entity from offering or providing, directly or through a
third party, including any potential distributors we may rely on in certain markets, anything of value to a foreign official with corrupt intent to
influence an award or continuation of business or to gain an unfair advantage, whether or not such conduct violates local laws. In addition, it
is illegal for a company that reports to the SEC to have false or inaccurate books or records or to fail to maintain a system of internal
accounting controls. We will also be required to maintain accurate information and control over sales and distributors’ activities that may fall
within the purview of the FCPA, including its books and records provisions and its anti-bribery provisions.
The standard of intent and knowledge under the FCPA’s anti-bribery provisions is minimal intent and knowledge are usually inferred from the
fact that bribery took place. The FCPA’s accounting provisions do not require intent. Violations of the FCPA’s anti-bribery provisions for
corporations and other business entities are subject to a fine of up to $2.0 million and officers, directors, stockholders, employees and agents
are subject to a fine of up to $100,000 and imprisonment for up to five years. Other countries, including the United Kingdom and other
Organisation for Economic Co-Operation and Development Anti-Bribery Convention members, have similar anti-corruption regulations, such
as the U.K. Bribery Act.
When marketing our testing products outside of the United States, we may be subject to foreign regulatory requirements governing human
clinical testing, prohibitions on the import of tissue necessary for us to perform our testing products or restrictions on the export of tissue
imposed by countries outside of the United States or the import of tissue into the United States, and marketing approval. These requirements
vary by jurisdiction, differ from those in the United States and may in some cases require us to perform additional pre-clinical or clinical
testing. In many countries outside of the United States, coverage, pricing and reimbursement approvals are also required.
Privacy and Security Laws
U.S. Data Privacy and Security Laws
HIPAA established comprehensive federal standards for the privacy and security of health information. In 2009, Congress enacted Subtitle D
of the Health Information Technology for Economic and Clinical Health Act (HITECH) provisions of the American Recovery and Reinvestment
Act of 2009. HITECH amended HIPAA and, among other things, expanded and strengthened HIPAA, created new targets for enforcement,
imposed new penalties for noncompliance and established new breach notification requirements. HIPAA applies to health plans, healthcare
clearing houses and healthcare providers that conduct certain healthcare transactions electronically (collectively, Covered Entities), as well
as individuals or entities that perform services for them involving the use, or disclosure of, individually identifiable health information or
"protected health information" (PHI) under HIPAA (Business Associates). Under HIPAA, as amended by the HITECH Act, HHS has issued
regulations to protect the privacy and security of PHI used or disclosed by Covered Entities and Business Associates. HIPAA also regulates
and standardizes the codes, formats and identifiers used in certain healthcare transactions and standardization of identifiers for health plans
and providers, for example insurance billing. Any non-compliance with HIPAA and HITECH and related penalties, could adversely impact our
business.
The HIPAA security standards require the adoption of administrative, physical and technical safeguards and the adoption of written security
policies and procedures to maintain the security of protected health information. Also, federal agencies are increasing their focus on the
importance of cybersecurity in protecting health information. For example, HHS outlined its cybersecurity strategy for the health care sector
on December 6, 2023, which builds on a national strategy published by the White House on March 1, 2023, and on February 16, 2024, the
HHS Office for Civil Rights (OCR) and the National Institute of Standards and Technology (NIST) announced the publication of a
cybersecurity resource guide for implementing HIPAA.
The HIPAA privacy regulations address the privacy of PHI by limiting the use and release of such information. They also set forth certain
rights that an individual has with respect to his or her PHI maintained by a covered entity, including the right to access or amend certain
records containing PHI, request an accounting of disclosures of PHI or to request restrictions on the use or disclosure of PHI. The HIPAA
breach notification regulations impose certain reporting requirements on Covered Entities and their Business Associates in the event of a
breach of PHI.
Covered Entities must report breaches of PHI that has not been encrypted or otherwise secured in accordance with guidance from the
Secretary of HHS (the Secretary). Breaches must be reported as soon as reasonably practicable, but no later than sixty days following
discovery of the breach. Reports must be made to affected individuals, the Secretary, and depending on the size of the breach, the local and
national media. Covered Entities like us are also
25
subject to the HHS HIPAA audit program and may be investigated in connection with a privacy or data security complaint.
Significant civil and criminal fines and other penalties may be imposed for violating HIPAA directly, and in connection with acts or omissions
of any agents, including downstream business associates, as determined according to the federal common law of agency. Civil penalties are
adjusted for inflation on an annual basis and can exceed one million dollars per year for failure to comply with a HIPAA requirement. A single
breach incident can violate multiple requirements. Additionally, a person who knowingly obtains or discloses PHI in violation of HIPAA may
face criminal penalties (including fines and imprisonment), which increase if the wrongful conduct involves false pretenses or the intent to
sell, transfer or use PHI for commercial advantage, personal gain or malicious harm. Covered Entities are also subject to enforcement by
state Attorneys General who were given authority to enforce HIPAA.
Additionally, while HIPAA does not create a private right of action allowing individuals to file suit against us in civil court for violations of
HIPAA, its standards have been used as the basis for duty of care cases in state civil suits such as those for negligence or recklessness in
the misuse or breach of PHI.
Further, to the extent that we submit electronic healthcare claims and payment transactions that do not comply with the transaction standards
established under HIPAA and HITECH, payments to us may be delayed or denied.
Even when HIPAA does not apply, according to the FTC, failing to take appropriate steps to keep consumers’ personal information secure
constitutes unfair acts or practices in or affecting commerce in violation of Section 5(a) of the FTC Act. The FTC expects a company’s data
security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and
complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities. Individually identifiable health
information is considered sensitive data that merits stronger safeguards. The FTC and states' Attorneys General have also brought
enforcement actions and prosecuted some data breach cases as unfair and/or deceptive acts or practices under the FTC Act and
comparable state laws.
The HIPAA privacy and security regulations establish a uniform federal "floor" and do not preempt state laws that are more stringent or
provide individuals with greater rights with respect to the privacy or security of, and access to, their records containing PHI or insofar as such
state laws apply to personal information that is broader in scope than PHI. Certain state laws govern the privacy and security of health-
related and other personal information in certain circumstances, some of which are more stringent than HIPAA and many of which differ from
each other in significant ways and may not have the same effect, thus complicating compliance efforts. Failure to comply with these laws,
where applicable, can result in the imposition of significant civil and/or criminal penalties and private litigation. The State of California, for
example, has implemented comprehensive laws and regulations. The California Confidentiality of Medical Information Act (CMIA), imposes
restrictive requirements regulating the use and disclosure of health information and other personally identifiable information. California has
also recently adopted the California Consumer Privacy Act of 2018 (CCPA), which went into effect January 1, 2020. The CCPA, among other
things, creates new data privacy obligations for covered companies and provides new privacy rights to California residents, including the right
to opt out of certain disclosures of their information. It also creates individual privacy rights for California consumers and increases the
privacy and security obligations of entities handling certain personal information. The CCPA provides for civil penalties for violations, as well
as a private right of action for data breaches that is expected to increase data breach litigation. Although the law includes limited exceptions,
including for PHI maintained by a Covered Entity or Business Associate under HIPAA and medical information maintained by healthcare
providers under the CMIA, it may regulate or impact our processing of personal information depending on the context. Further, the California
Privacy Rights Act (CPRA) went into effect January 1, 2023 strengthening the CCPA. The CPRA imposes additional data protection
obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for
higher risk data, and opt outs for certain uses of sensitive data and expands the application of the CCPA to all human resources personal
information of our California-based employees. It also created a new California data protection agency authorized to issue substantive
regulations and is expected to result in increased privacy and information security enforcement. Various states such as Colorado,
Connecticut, Delaware, Florida, Indiana, Iowa, Montana, Oregon, Tennessee, Texas, Utah and Virginia have enacted their own privacy laws
similar to the CCPA, and other states are considering proposals for such laws, all of which increases the complexity of compliance and the
risk of failures to comply.
Numerous other federal and state laws, including consumer protection laws and regulations, govern the collection, dissemination, use,
access to, confidentiality and security of patient health information. In addition, Congress and some states are considering new laws and
regulations that further protect the privacy and security of medical records or medical information. With the recent increase in publicity
regarding data breaches resulting in improper dissemination of consumer information, all 50 states have passed laws regulating the actions
that a business must take if it experiences a data breach, as defined by state law, including prompt disclosure within a specified amount
26
of time to affected individuals. In addition to data breach notification laws, some states have enacted statutes and rules requiring businesses
to reasonably protect certain types of personal information they hold or to otherwise comply with certain specified data security requirements
for personal information. Congress has also been considering similar federal legislation relating to data privacy and data protection.
Many states, such as Massachusetts, have also implemented genetic testing and privacy laws imposing specific patient consent
requirements and requirements for protecting test results. The interplay of federal and state laws regulating genetic information may be
subject to varying interpretations by courts and government agencies, creating complex compliance issues for us and potentially exposing us
to additional expense, adverse publicity and liability. Further, as regulatory focus on genetic privacy issues continues to increase and laws
and regulations concerning the protection of personal information expand and become more complex, these potential risks to our business
could intensify.
Information Blocking Rules
The Office of the National Coordinator for Health Information Technology (ONC), coordinates the ongoing development of standards to
enable interoperable health information technology infrastructure nationwide in the healthcare sector. In May 2020, ONC released the final
Information Blocking Rule to implement the interoperability and patient access provisions of the 21st Century Cures Act. We will need to
continually review our practices for conduct that could be considered as likely to interfere with access, exchange or use of electronic health
information, as those practices are prohibited by the Information Blocking Rule, unless one of the exceptions outlined in the Information
Blocking Rule applies. Among other things, the Information Blocking Rule requires us to provide patients with on-demand access to
laboratory test results. These requirements can be inconsistent with our obligations as a laboratory under state law and/or medical or ethical
standards. It is currently unclear how the ONC will approach delays in providing patient access in these situations. Healthcare providers
including laboratories will be subject to civil monetary penalties for violations of the Information Blocking Rule once the penalty regulations
are finalized. The amount of such penalties for laboratories is unknown, but the regulations for health industry networks (HINs), health
information exchanges (HIEs), and certified developers of health information technology allow for up to $1.0 million in penalties per violation.
GDPR and Foreign Laws
We are also subject to foreign privacy laws in the foreign jurisdictions in which we sell our testing products. The interpretation, application
and interplay of consumer and health-related data protection laws in the United States, Europe and elsewhere are often uncertain,
contradictory and in flux. In Europe, the General Data Protection Regulation (GDPR) went into full effect in May 2018. The GDPR implements
stringent operational requirements for processors and controllers of personal data, including, for example, expanded disclosures about how
personal information is collected and used, limitations on retention of information, increased requirements pertaining to health data and
pseudonymized (i.e., key-coded) data, mandatory data breach notification requirements, more robust rights for individuals in regard to their
personal data and higher standards for controllers to demonstrate that they have obtained valid consent for certain data processing activities.
It provides that European Union (EU), and European Economic Area (EEA), member states may make their own further laws and
regulations, which may impose further limitations, including in relation to the processing of biometric or health data, which may result in
differences between member state laws, limit our ability to use and share personal data, cause our costs to increase and/or harm our
business and/or financial condition.
Among other requirements, the GDPR also regulates transfers of personal data subject to the GDPR to third countries that have not been
found to provide adequate protection to such personal data, including the United States, and the efficacy and longevity of current transfer
mechanisms between the EU and the United States remains uncertain. For example, in 2016, the EU and the United States agreed to a
transfer framework for data transferred from the EU to the United States, called the Privacy Shield, but the Court of Justice of the EU
invalidated the Privacy Shield when it decided the case Maximilian Schrems vs. Facebook (Case C-311-18), known as Schrems II. However,
on July 10, 2023, the European Commission adopted an adequacy decision for a new mechanism for transferring data from the EU to the
United States – the EU-US Data Privacy Framework, which provides EU individuals with several new rights, including the right to obtain
access to their data, or obtain correction or deletion of incorrect or unlawfully handled data. The adequacy decision followed the signing of an
executive order introducing new binding safeguards to address the points raised in the Schrems II decision. Notably, the new obligations
were geared to ensure that data can be accessed by U.S. intelligence agencies only to the extent necessary and proportionate and to
establish an independent and impartial redress mechanism to handle complaints from Europeans concerning the collection of their data for
national security purposes. The European Commission will continually review developments in the United States along with its adequacy
decision. Adequacy decisions can be adapted or even withdrawn in the event of developments affecting the level of protection in the
27
applicable jurisdiction. Future actions of EU data protection authorities are difficult to predict. Some customers or other service providers may
respond to these evolving laws and regulations by asking us to make certain privacy or data-related contractual commitments that we are
unable or unwilling to make. This could lead to the loss of current or prospective customers or other business relationships.
Relatedly, following the United Kingdom’s withdrawal from the EU, the GDPR was implemented in the United Kingdom as the U.K. GDPR
with the U.K. GDPR sits alongside the amended U.K. Data Protection Act 2018, retains the GDPR in U.K. national law. Under the U.K.
GDPR, companies not established in the United Kingdom but who process personal data in relation to the offering of goods or services to
individuals in the United Kingdom, or to monitor their behavior will be subject to the U.K. GDPR – the requirements of which are (at this time)
largely aligned with those under the EU GDPR and as such, may lead to similar compliance and operational costs with potential fines of up to
£17.5 million or 4% of global turnover In June of 2021, the European Commission issued a decision, which will sunset on June 27, 2025
without further action, that the United Kingdom ensures an adequate level of protection for personal data transferred under the EU GDPR
from the EU to the United Kingdom. The Parliament of the United Kingdom is currently considering the Data Protection and Digital
Information Bill to harmonize the 2018 Data Protection Act, U.K. GDPR, and the Privacy and Electronic Communications Regulations under
one legislative framework.
Billing and Government Reimbursement for Clinical Laboratory Services
Medicare
Medicare coverage is limited to items and services, within the scope of a Medicare benefit category that are reasonable and necessary for
the diagnosis or treatment of an illness or injury. With respect to Medicare coverage, Palmetto GBA, the Medicare Administrative Contractor
(MAC) responsible for administering Medicare’s molecular diagnostic services program (MolDX Program), issued a Local Coverage
Determination (LCD) that provides coverage for our AVISE MTX test. The MAC responsible for administering Medicare claims submitted by
our laboratory, Noridian Healthcare Solutions (Noridian), has adopted Palmetto’s positive coverage policy, along with a related local coverage
article that identifies a unique billing identifier for this test.
®
Under Medicare, payment for our laboratory tests are generally made under the Clinical Laboratory Fee Schedule (CLFS) with payment
amounts assigned to specific procedure billing codes. In April 2014, Congress passed the Protecting Access to Medicare Act (PAMA), which
substantially changed the way in which Medicare sets the payment amounts for clinical laboratory services. Under PAMA, laboratories that
receive the majority of their Medicare revenue from payments made under the CLFS or the Physician Fee Schedule (PFS) are required to
report to CMS, beginning in 2017 and every three years thereafter (or annually for "advanced diagnostic laboratory tests" (ADLTs)), private
payor payment rates and volumes for their tests. Laboratories that fail to report the required payment information may be subject to
substantial civil monetary penalties. As required under PAMA, CMS uses the rates and volumes reported by laboratories to develop Medicare
payment rates for laboratory tests equal to the volume-weighted median of the private payor payment rates for the tests.
On June 23, 2016, CMS published the final rule implementing the reporting and rate-setting requirements under PAMA. For tests furnished
on or after January 1, 2018, Medicare payments for clinical diagnostic laboratory tests (CDLTs) are based upon these reported private payor
rates. For CDLTs assigned a new or substantially revised Current Procedural Terminology (CPT), because there is no comparable existing
CDLT, CMS will set the initial payment rates using the gap-fill methodology, as under prior law. Initial payment rates for new ADLTs will be
based on the actual list charge. Any reductions to payment rates resulting from the new methodology are limited to up to 10% per test per
year in each of the years 2018 through 2020. As noted below, federal law has delayed implementation of further reductions until 2024, at
which time the reduction cap will rise to 15% per test per year. PAMA did not impact Medicare reimbursement for AVISE CTD in 2022
compared to levels experienced in 2021. Additionally, PAMA and changes to the PFS will not have a significant impact to Medicare
reimbursement for AVISE CTD in 2024 compared to levels experienced in 2023.
®
®
Since December 2019, Congress has passed a series of laws to modify PAMA’s statutory requirements related to the data reporting period
and phase-in of payment reductions under the CLFS or CDLTs that are not ADLTs Most recently, the Further Continuing Appropriations and
Other Extensions Act of 2024 (Pub.L. 118-22, enacted on November 16, 2023) further delayed the reporting requirement as well as the
application of the 15% phase-in reduction. Under these statutory provisions, the next data reporting period for CDLTs that are not ADLTs will
be January 1, 2025 through March 31, 2025, and will be based on the most recent data collection period of January 1, 2019 through June 30,
2019. After this data reporting period, the three-year data reporting cycle for these tests will resume (e.g., 2028, 2031, etc.).
28
The same series of laws modified the phase-in of payment reductions resulting from private payor rate implementation so that a 0.0%
reduction limit was applied for calendar years (CYs) 2021 through 2023, as compared to the payment amounts for a test the preceding year.
The Further Continuing Appropriations and Other Extensions Act of 2024 further applied a 0.0% reduction limit for CY 2024. Consequently,
payment may not be reduced by more than 15% per year for CYs 2025 through 2027 as compared to the payment amounts established for a
test the prior year.
PAMA also authorized the adoption of new, temporary billing codes and unique test identifiers for FDA-cleared or approved tests, as well as
ADLTs. The American Medical Association's (AMA) CPT Editorial Panel approved a proposal to create a new section of billing codes called
Proprietary Laboratory Analyses (PLA) codes, to facilitate implementation of this section of PAMA. The AMA publishes approved codes on a
quarterly basis. We requested a PLA code and in the quarter ended March 31, 2022, CMS agreed, effective April 1, 2022, to recognize a new
PLA code for our protein-based test, AVISE Lupus.
®
Billing for diagnostic testing can be complicated. Depending on the billing arrangement and applicable law, we must bill various parties, such
as commercial payors, Medicare, Medicaid, physicians, hospitals, employer groups and patients, all of which have different billing
requirements. Additionally, compliance with applicable laws and regulations as well as internal compliance policies and procedures adds
further complexity to the billing process. Changes in laws and regulations could negatively impact our ability to bill our clients or increase our
costs. CMS also establishes new procedures and continuously evaluates and implements changes to the reimbursement process for billing
government healthcare programs. Missing or incorrect information on test requisitions adds complexity to and slows the billing process,
creates backlogs of unbilled tests, and generally increases the aging of accounts receivable and bad debt expense. Failing to bill timely or
correctly may have negative consequences for us, such as not being reimbursed for our services or experiencing an increase in the aging of
our accounts receivable, which could adversely impact our results of operations and cash flows. Failure to comply with applicable laws
relating to billing federal healthcare programs could also lead to various penalties, including:
▪
▪
▪
▪
▪
overpayments and recoupments of reimbursement received;
exclusion from participation in Medicare/Medicaid programs;
asset forfeitures;
civil and criminal fines and penalties; and
the loss of various licenses, certificates and authorizations necessary to operate our business.
Any of these penalties or sanctions could have a material adverse effect on our results of operations or cash flows.
Healthcare Reform
In March 2010, the Affordable Care Act (ACA) was enacted in the United States and made a number of substantial changes to the way
healthcare is financed both by governmental and private payors. Although the ACA included a medical device tax, the tax never went into
effect and was fully repealed by Congress with enactment of the 2019 federal spending package signed into law on December 20, 2019.
Since the ACA’s enactment, there have been judicial and Congressional challenges to certain aspects of the ACA, and as a result, certain
sections of the ACA have not been fully implemented or were effectively repealed. However, following several years of litigation in the federal
courts, in June 2021, the U.S. Supreme Court (the Supreme Court) upheld the ACA when it dismissed a legal challenge to the ACA’s
constitutionality. Further legislative and regulatory changes under the ACA remain possible, although the current Democrat-led presidential
administration has been taking steps to strengthen the ACA. Future changes or additions to the ACA, the Medicare and Medicaid programs
and changes stemming from other healthcare reform measures, especially with regard to healthcare access, financing or other legislation in
individual states, could have a material adverse effect on the healthcare industry in the United States. The uncertainty around the future of
the ACA, and in particular the impact to reimbursement levels and the number of insured individuals, may lead to delay in the purchasing
decisions of our customers.
In addition to the ACA, there will likely continue to be proposals by legislators at both the federal and state levels, regulators and private third-
party payors to reduce costs while expanding individual healthcare benefits.
Environmental and Other Regulatory Requirements
Our laboratory is subject on an ongoing basis to federal, state and local laws and regulations governing the use, storage, handling and
disposal of regulated medical waste, hazardous waste and biohazardous waste, including
29
chemicals, biological agents and compounds and blood and other tissue specimens. Typically, we use licensed or otherwise qualified outside
vendors to dispose of this waste. However, many of these laws and regulations provide for strict liability, holding a party potentially liable
without regard to fault or negligence. As a result, we could be held liable for damages and fines if our, or others', business operations or other
actions result in contamination of the environment or personal injury due to exposure to hazardous materials. Our costs for complying with
these laws and regulations cannot be estimated or predicted and depends on a number of factors, including the amount and nature of waste
we produce (which depends in part on the number of tests we perform) and the terms we negotiate with our waste disposal vendors. Since
inception, we have disposed of all hazardous and/or medical waste that we produced across our entire business through environmentally
sound methods.
Our operations are also subject to extensive requirements established by the U.S. Occupational Safety and Health Administration relating to
workplace safety for healthcare employees, including requirements to develop and implement programs to protect workers from exposure to
blood-borne pathogens by preventing or minimizing any exposure through needle stick or similar penetrating injuries.
Human Capital
As of December 31, 2023, we had a total of 179 employees: 174 full-time employees and 5 part-time employees. This includes 44 in
laboratory operations, 9 in research and development, 49 in sales and marketing and 72 in general and administrative functions. All of our
employees are located in the United States, none of which are represented by a labor union or covered by a collective bargaining agreement.
We consider relations with our employees to be good.
We recognize that attracting, motivating and retaining talent at all levels is vital to our continued success. Our employees are a significant
asset and we aim to create an equitable, inclusive and empowering environment in which our employees can grow and advance their
careers, with the overall goal of developing, retaining and expanding our workforce, as needed, to support our current pipeline and future
business goals. By focusing on employee retention and engagement, we also improve our ability to support our business and operations, our
pipeline, and also protect the long-term interests of our securityholders. Our success also depends on our ability to attract, engage and retain
a diverse group of employees. Our efforts to recruit and retain a diverse and passionate workforce include providing competitive
compensation and benefits packages and efforts to ensure our employees' voices are heard.
We value innovation, passion, data-driven decision making, persistence and honesty, and are building a diverse environment where our
employees can thrive and be inspired to make exceptional contributions to bring novel testing products to patients.
Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, motivating and integrating our existing and
future employees. The principal purposes of our equity incentive plans are to attract, retain and motivate selected employees and directors
through grants of stock-based compensation awards and payments of cash-based performance bonus awards, in order to increase
stockholder value and the success of our company by motivating our employees to perform to the best of their abilities and achieve our
objectives. We are committed to providing a competitive and comprehensive benefits package to our employees. Our benefits package
provides a balance of protection along with the flexibility to meet the individual health and wellness needs of our employees. We plan to
continue to refine our efforts related to optimizing our use of human capital as we grow, including improvements in the way we hire, develop,
motivate and retain employees.
We conduct periodic anonymous employee surveys aimed at measuring the overall satisfaction of our team and make efforts to address
issues brought to our attention. The results consistently show that our employees consider their work valuable and meaningful.

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 included in this Annual Report on Form 10-K, including our financial statements and related notes
and "Management’s Discussion and Analysis of Financial Condition and Results of Operations," before making an investment decision to
purchase or sell shares of our common stock. If any of the following risks are realized, our business, financial condition, results of operations
and prospects could be materially and adversely affected. In that event, the trading price of our common stock could decline, and you could
lose part or all of your investment. The risks described below are not the only ones that we may face, and additional risks or uncertainties not
known to us or that we currently deem immaterial may also impair our business and future prospects.
Summary Risk Factors
The risk factors described below are a summary of the principal risk factors associated with an investment in us. These are not the only risks
we face. You should carefully consider these risk factors, together with the risk factors set forth in this Item 1A:
• We have a history of losses, we expect to incur net losses in the future and we may not be able to generate sufficient revenue to
achieve and maintain profitability;
•
•
If third-party payors do not provide coverage and adequate reimbursement for our testing products, or they breach, rescind or modify
their contracts or reimbursement policies or delay payments for our testing products, or if we or our partners are unable to
successfully negotiate payor contracts, our commercial success could be materially compromised;
In the near-term, we expect that our financial results will depend primarily on sales of our testing products, and we will need to
generate sufficient revenue from these testing products to grow our business;
• We may be unable to manage our growth effectively, which could make it difficult to execute our business strategy;
• Our commercial success depends on attaining and maintaining significant market acceptance of our testing products among
rheumatologists, patients, third-party payors and others in the medical community;
• We rely on sole suppliers for some of the reagents, equipment and other materials used in our testing products, and we may not be
able to fund replacements or transition to alternative suppliers;
•
•
If we are unable to support demand for our current testing products or any of our future testing products or solutions, our business
could suffer;
If we are unable to compete successfully, we may be unable to increase or sustain our revenue or achieve profitability;
• Developing new testing products involves a lengthy and complex process, and we may not be able to commercialize on a timely
basis, or at all, other testing products we are developing;
•
If our sole clinical laboratory facility becomes damaged or inoperable, we are required to vacate our existing facility or we are unable
to expand our existing facility as needed, we will be unable to perform our testing services and our business will be harmed;
32
• We may require substantial additional capital to finance our planned operations, which may not be available to us on acceptable
terms or at all. Our failure to obtain additional financing when needed on acceptable terms, or at all, could force us to delay, limit,
reduce or eliminate our product development programs, commercialization efforts or other operations;
• We conduct business in a heavily regulated industry. Complying with the numerous statutes and regulations pertaining to our
business is expensive and time-consuming, and any failure by us, our consultants or commercial partners to comply could result in
substantial penalties;
• We have previously and may again in the future be required to modify our business practices, pay fines, incur significant expenses or
experience losses due to litigation or governmental investigations;
•
•
•
The FDA may disagree with our assessment that our AVISE® test products and any other tests we may develop are LDTs and
determine that such test products are medical devices subject to the FDCA and FDA regulations;
If we are unable to maintain intellectual property protection, our competitive position could be harmed; and
If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties or
otherwise experience disruptions to our business relationships with our licensors, we could lose license rights that are important to
our business.
Risks Related to Our Business and Strategy
We have a history of losses, we expect to incur net losses in the future and we may not be able to generate sufficient revenue to
achieve and maintain profitability.
We have incurred net losses since our inception. For the years ended December 31, 2023 and 2022, we incurred net losses of $23.7 million
and $47.4 million, respectively, and we expect to incur additional losses in 2024 and in future years. As of December 31, 2023, we had an
accumulated deficit of $279.2 million. Over the next several years, we expect to continue to devote substantially all of our resources to
increase adoption of, and reimbursement for, our testing products and to develop future testing products. We may not be able to generate
sufficient revenue to achieve and maintain profitability. Our failure to achieve and maintain profitability in the future could cause the market
price of our common stock to decline and materially and adversely affect our prospects and business.
If third-party payors do not provide coverage and adequate reimbursement for our testing products, or they breach, rescind or
modify their contracts or reimbursement policies or delay payments for our testing products, or if we or our partners are unable to
successfully negotiate payor contracts, our commercial success could be compromised.
Successful commercialization of our testing products depends, in large part, on the availability of coverage and adequate reimbursement
from third-party payors, including government payors, such as Medicare and Medicaid and commercial payors. For the testing products that
we develop and commercialize, each third-party payor decides whether to cover the product, the amount it will reimburse for a covered
product and the specific conditions for reimbursement.
Reimbursement by third-party payors may depend on a number of factors, including the payor’s determination that tests using our
technologies are:
•
not experimental or investigational;
• medically necessary;
•
•
•
•
•
demonstrated to lead to improved patient outcomes;
appropriate for the specific patient;
cost-saving or cost-effective;
supported by peer-reviewed medical journals; and
included in clinical guidelines.
If we are unable to provide third-party payors with sufficient evidence of the clinical utility and validity of our test, they may not provide
coverage, or may provide limited coverage, which will adversely affect our revenue and our
33
ability to succeed. In addition, clinicians may be less likely to order a test unless third-party payors pay a substantial portion of the test price.
Therefore, coverage determinations and reimbursement levels and conditions are critical to commercial success, and if we are not able to
secure positive coverage determinations and reimbursement levels, our business will be materially adversely affected.
Third-party payors and other entities also conduct technology assessments of new medical tests and devices and provide and/or sell the
results of their assessments to other parties. These assessments may be and have been used by third-party payors and healthcare providers
as grounds to deny coverage for or refuse to use a test or procedure, including our tests. In addition, third-party payors have increased their
efforts to control the cost, utilization and delivery of healthcare services. These measures have resulted in reduced payment rates and
decreased utilization for the diagnostics industry.

Effective April 25, 2012, Palmetto GBA, the Medicare MolDx Program, assigned the AVISE MTX assay a unique identifier and determined
that the test meets the applicable Medicare coverage criteria to support dose optimization and therapeutic decision making for patients
diagnosed with RA on methotrexate. Our current Medicare Administrative Contractor, Noridian, has adopted this coverage policy. In addition,
and effective April 1, 2022, CMS agreed to recognize a new PLA code for our protein-based test, AVISE Lupus. Noridian priced this PLA
code at $1,085 per test. To determine pricing beyond 2022, CMS recommended crosswalking AVISE Lupus (0312U) to Vectra (81490) at a
rate of $840.65 per test. This pricing was finalized on the 2023 CLFS and is effective from January 1, 2023 through December 31, 2025. A
pricing determination is not synonymous with a coverage determination. Having a price associated with the PLA code for any particular test
does not secure coverage or reimbursement for that PLA code from Medicare or any other third-party payor. So, in an effort to improve
transparency regarding Medicare support of AVISE Lupus, we submitted a formal request to Noridian for coverage of our AVISE Lupus test
under the new PLA Code. On September 27, 2022, we received notice that Noridian has deemed our application for an LCD to be valid.
Ultimately receiving a favorable LCD is uncertain and may be time-consuming, resource intensive and require multiple quarterly or annual
periods to complete. We have faced and may again face or continue to face challenges relating to commercial payor claim processing and
revenue with our tests.
®
®
®
®
Other third-party payors make their own decisions as to whether to establish a policy to reimburse our testing products. Because approvals
must be sought on a payor-by-payor basis, establishing broad coverage is a time-consuming and costly process. There are many third-party
payors who have not yet established a coverage policy applicable to our testing products. In addition, several commercial payors issued non-
coverage policies with respect to AVISE Lupus, determining that AVISE Lupus does not meet the medical criteria for coverage and is
considered investigational and/or experimental.
®
®
While our testing products are reimbursed by a number of third-party payors, we do not currently have contracts with significant private
payors. We have in the past, and will likely in the future, experience delays and temporary interruptions in the receipt of payments from third-
party payors due to changes in their internal processes, documentation requirements and other issues, which could cause our revenue to
fluctuate from period to period.
If we are not successful in reversing existing non-coverage policies, or if other third-party payors issue negative coverage policies, these
policies could have a material adverse effect on our business and operations. Even if many third-party payors currently reimburse for our
testing products, such payors have in the past and may again withdraw coverage at any time, review and adjust the rate of reimbursement,
require co-payments from patients or stop paying for our testing products altogether, any of which could materially reduce our revenue.
In the near-term, we expect that our financial results will depend primarily on sales of our testing products, and we will need to
generate sufficient revenue from these testing products to grow our business.
A significant majority of our historical revenue has been derived from the sale of our AVISE CTD testing product, which we commercially
launched in 2012. In the near term, we expect to continue to derive a majority of our revenue from sales of AVISE CTD. We are in various
stages of research and development with respect to other testing products that we may offer, but there can be no assurance that we will be
able to commercialize these testing products.
®
®
The demand for our testing products may decrease or may not continue to increase at historical rates for a number of reasons. In addition, at
any point in time we may decide to no longer commercialize any of our testing products for any number of reasons. While we have
experienced revenue growth from the sale of our testing products, we may not be able to sustain this growth or maintain existing revenue
levels. Further, we cannot ensure the continued availability of our testing products in commercial quantities at acceptable costs. If we are
unable to increase sales of our testing products, expand reimbursement for our testing products, or successfully develop and commercialize
34
additional testing products, our revenue and our ability to achieve and sustain profitability would be impaired, and the market price of our
common stock could decline.
Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.
Our operations could be subject to earthquakes, power shortages, telecommunications failures, water shortages, floods, hurricanes,
typhoons, fires, extreme weather conditions, medical epidemics, political instability, acts of war, including the current conflict in Ukraine and
the Middle East, and other natural or manmade disasters (which may be exacerbated due to climate change) or business interruptions, for
which we are predominantly self-insured. We rely on third-party manufacturers to produce our testing products. Our ability to obtain clinical
supplies of our testing products could be disrupted if the operations of these suppliers were affected by a man-made or natural disaster or
other business interruption. In addition, our corporate headquarters is located in Vista, California near major earthquake faults and fire zones,
and the ultimate impact on us of being located near major earthquake faults and fire zones and being consolidated in a certain geographical
area is unknown. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and
increase our costs and expenses.
If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate and timely
financial statements could be impaired, investors may lose confidence in our financial reporting and the trading price of our
common stock may decline.
Pursuant to Section 404 of Sarbanes-Oxley, our management is required to report upon the effectiveness of our internal control over financial
reporting. When we lose our status as an “emerging growth company” and reach an accelerated filer threshold, our independent registered
public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting. The rules governing the
standards that must be met for management to assess our internal control over financial reporting are complex and require significant
documentation, testing and possible remediation. To comply with the requirements of being a reporting company under the Exchange Act, we
may need to upgrade our information technology systems; implement additional financial and management controls, reporting systems and
procedures; and/or hire additional accounting and finance staff as we grow. If we or, if required, our auditors are unable to conclude that our
internal control over financial reporting is effective, investors may lose confidence in our financial reporting and the trading price of our
common stock may decline.
On November 13, 2022, management and the Audit Committee determined that we made certain errors in revenue resulting from erroneous
and duplicate billings related to changes in billing practices. The errors were due to the inadequate design, implementation and precision of
internal controls and procedures to evaluate and monitor the accounting for revenue recognition. As a result, revenue and accounts
receivable were overstated and other liabilities was understated for the quarter and year to date periods ended June 30, 2022.
We concluded that these were material errors in the financial statements requiring a restatement of the Form 10-Q for the three and six
months ended June 30, 2022. Accordingly, management determined that this control deficiency constituted a material weakness as of
December 31, 2022.
In response to the material weaknesses, and as previously disclosed in Item 9A of our annual report on Form 10-K for the year ended
December 31, 2022, we implemented a remediation plan which included, but was not limited to, evaluating the staffing level, skills and
qualification of accounting department personnel, enhancement of our existing control structure and processes for revenue recognition and
improving the detailed review process of our revenue recognition models. The enhancements made to our control environment were in place
as of December 31, 2023, and based on the evaluation of relevant internal controls, management has concluded that the material
weaknesses previously identified have been remediated as of December 31, 2023.
We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal control over financial reporting in
the future. Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial
condition, results of operations or cash flows. If we are unable to conclude that our internal control over financial reporting is effective, or if
our independent registered public accounting firm determines we have a material weakness or significant deficiency in our internal control
over financial reporting once that firm begin its Section 404 reviews, investors may lose confidence in the accuracy and completeness of our
financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by Nasdaq, the
SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement
or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.
35
We may be unable to manage our growth effectively, which could make it difficult to execute our business strategy.
In addition to the need to scale our testing capacity, our future growth plans may also impose significant added responsibilities on
management, including the need to identify, recruit, train and integrate additional employees and the need to manage additional relationships
with various partners, suppliers and other third parties. In addition, if we were to experience rapid and significant growth, our administrative
and operational infrastructure may be strained, requiring us to expand our financial, development, regulatory, manufacturing, marketing and
sales capabilities or contract with third parties to provide these capabilities for us. Our ability to manage our business and growth, as well as
function as a public company, will require us to continue to improve our operational, financial and management controls, reporting systems
and procedures. The time and resources required to optimize these systems is uncertain, and failure to complete optimization in a timely and
efficient manner could adversely affect our operations. If we are unable to manage our ongoing and future growth effectively, it may be
difficult for us to execute our business strategy and our business could be harmed.
Our commercial success depends upon attaining and maintaining significant market acceptance of our testing products among
rheumatologists, patients, third-party payors and others in the medical community.
Our success depends on our ability to continue to develop and market testing products that are recognized and accepted as safe, effective,
reliable and cost effective, and any testing product that we offer may not gain or maintain market acceptance among rheumatologists, third-
party payors, patients or the medical community. Market acceptance of our testing products depends on a number of factors, including:
•
•
•
•
•
•
•
•
•
the perceived accuracy of our test results by rheumatologists and patients;
the potential and perceived advantages of our testing products over alternative products;
the demonstration of the performance and clinical validity of our testing products in clinical studies, the results of which, may not
replicate the positive results from earlier studies;
the introduction of new tests that compete with our testing products;
the product cost in relation to alternative products;
publicity concerning our testing products or competing products and treatments;
the availability of coverage and adequate reimbursement by third-party payors, including government authorities;
relative convenience and ease of administration; and
the effectiveness of our sales and marketing efforts.
In addition, if we or our future partners have to withdraw a product from the market, it could harm our business and/or impact market
acceptance of our other testing products. Further, our AVISE testing products consist of various biomarkers, any of which could
independently encounter issues with manufacturing, supply or overall quality. If any of the biomarkers in our AVISE CTD test were to
encounter any issues, we may experience an impact in the overall success of AVISE CTD as a whole, including a reduction in ASP or
overall revenue, until such time as it can be remedied. Moreover, if our testing products do not achieve an adequate level of acceptance by
rheumatologists, hospitals, third-party payors or patients, we may not generate sufficient revenue from that testing product and may not
become or remain profitable. Our efforts to educate the medical community and third-party payors regarding the benefits of our testing
products may require significant resources and may never be successful.
®
®
®
We may experience limits on our revenue if rheumatologists decide not to order our testing products or if we are otherwise unable
to create or maintain demand for our testing products.
If we are unable to create or maintain demand for our testing products in sufficient volume, we may not generate sufficient revenue to
become profitable. To generate increased demand, we will need to continue to educate rheumatologists about the benefits of our testing
products through publications in peer-reviewed medical journals, presentations at medical conferences and other similar means. For
example, in the fourth quarter of 2023, we were featured in five scientific presentations at the 2023 ACR Annual Conference, ACR
Convergence 2023. We will also need to generate demand for our testing products through one-on-one education by our sales force. We
also plan to focus on educating patients about the benefits of these testing products, which we believe will be necessary to generate further
demand. In addition, our inability to obtain and maintain coverage and adequate reimbursement
36
from third-party payors may limit adoption by rheumatologists, as well as third-party payors exerting pressure on rheumatologists and
healthcare providers to order in-network testing products which could adversely affect our revenue.
Rheumatologists may rely on guidelines issued by industry groups regarding the diagnosis, prognosis, treatment and monitoring of
autoimmune and autoimmune-related diseases, and the monitoring of the effectiveness of therapeutic drugs used to treat such diseases
before utilizing any diagnostic test or monitoring solution.
The sizes of the markets for our testing products have not been established with precision and may be smaller than we estimate.
Our estimates of the annual total addressable markets for our current and potential future testing products are based on a number of internal
and third-party estimates. These include, without limitation, the number of patients with autoimmune and autoimmune-related diseases and
the assumed prices at which we can sell testing products and our partners can sell therapeutics in markets that have not been established.
While we believe our assumptions and the data underlying our estimates are reasonable, these assumptions and estimates may not be
correct and the conditions supporting our assumptions or estimates may change at any time, thereby reducing the predictive accuracy of
these underlying factors. As a result, our estimates of the annual total addressable market for our current and potential future testing
products may prove to be incorrect. If the actual number of patients who would benefit from our testing products, the price at which we and
our partners can sell future testing products, or the annual total addressable market for our testing products is smaller than we have
estimated, it may impair our sales growth and have an adverse impact on our business.
We may expend our limited resources to pursue a particular testing product and fail to capitalize on other testing products that
may be more profitable or for which there is a greater likelihood of success.
Because we have limited financial and managerial resources, we focus on specific testing products. As a result, we may forego or delay
pursuit of opportunities with others that could have had greater commercial potential. Our resource allocation decisions may cause us to fail
to capitalize on viable commercial products or profitable market opportunities. In addition, our spending on current and future research and
development programs for testing products may not yield any commercially viable testing products. If we do not accurately evaluate the
commercial potential or target market for a potential testing product, we may forego other similar arrangements which would have been more
advantageous for us to pursue.
Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our
operating results to fall below expectations or any guidance we may provide.
Our quarterly and annual operating results may fluctuate significantly, which makes it difficult for us to predict our future operating results.
These fluctuations may occur due to a variety of factors, many of which are outside of our control, including, but not limited to:
•
•
•
•
•
•
•
•
•
our ability to successfully market and sell our AVISE testing products;
®
the extent to which our current testing and future testing products, if any, are eligible for coverage and reimbursement from third-
party payors;
the timing and cost of, and level of investment in, research, development, regulatory approval and commercialization activities
relating to our testing products, which may change from time to time, and our ability to successfully commercialize new testing
products;
the cost of supplies, equipment and materials used for our testing products and laboratory operations, which may vary depending on
the quantity of production and the terms of our agreements with third-party suppliers and manufacturers;
expenditures that we may incur to acquire, develop or commercialize additional testing products and technologies;
the level of demand for our testing products, which may vary significantly;
the receipt, timing and mix of revenue for our testing products;
future accounting pronouncements or changes in our accounting policies;
our ability to collect timely reimbursement for our tests;
37
•
•
the rate and extent to which payors make an overpayment determination and require us to return all or some portion of payments
which we received in a prior period; and
the timing and success or failure of competing products, or any other change in the competitive landscape of our industry, including
consolidation among our competitors or partners.
The cumulative effects of these factors could result in large fluctuations and unpredictability in our quarterly and annual operating results. For
instance during 2023, our operating results varied due, in part, to our efforts regarding revenue cycle management. As a result, comparing
our operating results on a period-to-period basis may not be meaningful. Investors should not rely on our past results as an indication of our
future performance.
This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any
period. If our revenue or operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the
market, it could have a material adverse effect on our business, financial condition and results of operations.
We rely on sole suppliers for some of the reagents, equipment and other materials used in our testing products, and a sole third-
party fulfillment center used to supply healthcare providers with our testing products, and we may not be able to find replacements
or transition to alternative suppliers or fulfillment centers.
We rely on sole suppliers for critical supply of reagents, equipment and other materials that we use to perform the tests that comprise our
testing products. We also purchase components used in our specimen collection and transportation kits from sole-source suppliers. Some of
these items are unique to these suppliers and vendors. While we have developed alternate sourcing strategies for many of these materials
and vendors, we cannot be certain whether these strategies will be effective or the alternative sources will be available when we need them.
We are not a major customer of some of our suppliers, and these suppliers may therefore give other customers’ needs higher priority than
ours. If our suppliers can no longer provide us with the materials we need to perform the tests that comprise our testing products, if the
materials do not meet our quality specifications, or if we cannot obtain acceptable substitute materials, an interruption in test processing
could occur and, in certain circumstances, we may be required to amend or cancel test results we have issued. Additionally, if we are unable
to remedy future potential quality issues with unique reagent suppliers, or otherwise find a supplier for future biomarkers with issues, we may
experience difficulties obtaining market acceptance for our products. Moreover, any issues with quality may result in a change from time to
time of the composition of our tests, including our AVISE CTD test, which could impact the average selling price and revenues received from
sales of such test.
®
In addition, if we should encounter delays or difficulties in securing the quality and quantity of equipment we require for our testing products,
we may need to reconfigure our test processes, which could result in an interruption in sales. Any such interruption may significantly affect
our future revenue and harm our customer relations and reputation. In addition, in order to mitigate these risks, we may need to maintain
inventories of these supplies at higher levels than would be the case if multiple sources of supply were available.
We rely on a third party as our sole fulfillment center in Florida to supply healthcare providers with our testing products. Our sole fulfillment
center could be harmed or rendered inoperable by natural or man-made disasters, including fire, earthquake, hurricane, flooding, pandemics
or other disease outbreaks and power outages, which may render it difficult or impossible for us to supply healthcare providers with our
testing products for some period of time. The inability to supply healthcare providers with our testing products or the backlog of tests that
could develop if our sole fulfillment center is inoperable for even a short period of time, may result in the loss of customers or harm to our
reputation or business relationships, and we may be unable to regain those customers or repair our reputation in the future. Furthermore, our
sole fulfillment center could be costly and time-consuming to repair or replace. If our sole fulfillment center is destroyed or otherwise rendered
inoperable, we may have difficulty replacing this fulfillment center and there can be no assurance we could do so in a timely manner, on
terms favorable to us or at all.
If we are unable to support demand for our current testing products or any of our future testing products or solutions, our
business could suffer.
If demand for our testing products or any of our future testing products or solutions grows, we will need to continue to scale our testing
capacity and processing technology, expand customer service, billing and systems processes and enhance our internal quality assurance
program. We may also need additional certified laboratory scientists and other scientific and technical personnel to process higher volumes
of our testing products. We cannot assure you that any increases in scale, related improvements and quality assurance will be successfully
implemented or that appropriate personnel will be available. We will also need to purchase additional equipment, some of which can
38
take several months or more to procure, setup and validate, and increase our software and computing capacity to meet increased demand.
Failure to implement necessary procedures, transition to new processes, hire the necessary personnel, obtain any necessary additional
equipment and increase software and computing capacity could result in higher costs of processing tests or inability to meet demand. There
can be no assurance that we will be able to perform our testing on a timely basis at a level consistent with demand, or that our efforts to scale
our operations, expand our personnel, equipment, software and computing capacities, or implement process enhancements will be
successfully implemented and will not negatively affect the quality of test results. In addition, there can be no assurance that we will have
adequate space in our laboratory facility to accommodate such required expansion. We are also currently collaborating with third parties in
an effort to implement multiplex technology in our laboratory. We may experience difficulties securing a partner for this technology and
integrating such technology into our existing laboratory operations, which could affect our ability to meet demand for our testing products. If
we encounter difficulty meeting market demand or quality standards, our reputation could be harmed and our future prospects and our
business could suffer.
Billing for our testing products is complex, and we must dedicate substantial time and resources to the billing process to be paid
for our testing products.
Billing for our testing products is complex, time consuming and expensive. Depending on the billing arrangement and applicable law, we bill
various third-party payors, including Medicare and Medicaid, and commercial payors, as well as patients, all of which have different billing
requirements. We generally bill third-party payors for our testing products and pursue reimbursement on a case-by-case basis where pricing
contracts are not in place. We may also face increased risk in our collection efforts, including long collection cycles and potential delays in
claims processing, which could adversely affect our business, results of operations and financial condition.
Several factors contribute to the complexity of the billing process, including:
•
•
•
•
•
•
•
•
•
•
differences between the list price for our testing products and the reimbursement rates of third-party payors;
compliance with complex federal and state regulations related to billing Medicare and Medicaid;
disputes among third-party payors as to which party is responsible for payment;
differences in coverage among third-party payors;
the effect of patient deductibles, co-payments or co-insurance;
differences in information and billing requirements among third-party payors;
changes to billing codes used for our testing products;
risk of government audits related to billing;
incorrect or missing billing information; and
the resources required to manage the billing and claims appeals process.
We use standard industry billing codes, known as CPT codes, to bill for our testing products. If these codes were to change, there is risk that
errors could be made in the claim adjudication process. Such errors can occur with claims submission, third-party transmission or in the
processing of the claim by the payor. Claim adjudication errors may result in a delay in payment processing or a reduction in the amount of
the payment received.
As we introduce new testing products, we will need to add new codes to our billing process as well as our financial reporting systems. Failure
or delays in effecting these changes in external billing and internal systems and processes could negatively affect our collection rates,
revenue and cost of collecting.
Our billing activities require us to implement compliance procedures and oversight, train and monitor our employees, and undertake internal
audits to evaluate compliance with applicable laws and regulations as well as internal compliance policies and procedures. Payors also
conduct external audits to evaluate payments, which add further complexity to the billing process. If the payor makes an overpayment
determination, there is a risk that we may be required to return all or some portion of prior payments we have received. Additionally, providers
and suppliers must report and return overpayments received from the Medicare and Medicaid programs within 60 days of identification.
Failure to identify and return such overpayments exposes the provider or supplier to liability under the federal False Claims Act.

Additionally, from time to time, third-party payors change processes that may affect timely payment. These changes have in the past and
may again result in uneven cash flow or impact the timing of revenue recognized with these payors. With respect to payments received from
government healthcare programs, factors such as a prolonged government shutdown could cause significant regulatory delays or could
result in attempts to reduce payments made to us by federal healthcare programs. In addition, third-party payors may refuse to ultimately
make payment if their processes and requirements have not been met on a timely basis. These billing complexities, and the related
uncertainty in obtaining payment for our testing products could negatively affect our revenue and cash flow, our ability to achieve profitability,
and the consistency and comparability of our results of operations.
In 2023, Noridian posted the calendar year 2024 Medicare Physician Fee Schedule (MPFS), and CLFS, which establishes the
reimbursement rates to be paid by Medicare for our jurisdiction for services performed on or after January 1, 2024. PAMA and changes to the
PFS did not have a significant impact to Medicare reimbursement for AVISE CTD in 2024 compared to levels experienced in 2023. Revenue
from Medicare comprised 34% and 39% of our revenue for the years ended December 31, 2023 and 2022, respectively. Revenue from the
sale of our AVISE CTD testing products comprised 88% and 84% of our revenue for the years ended December 31, 2023 and 2022,
respectively.

We also rely on a third-party provider to provide revenue cycle management software systems for certain processing and collection functions.
In the past, we have experienced delays in claims processing as a result of our third-party provider making changes to its invoicing system,
as well as not submitting claims to payors within the timeframe required. If claims for our testing products are not submitted to payors on a
timely basis, or if we are required to switch to a different systems provider, it could have an adverse effect on our revenue and our business.
Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover
them or that our trade secrets will be misappropriated or disclosed.
At times, we share our proprietary technology and confidential information, including trade secrets, with third parties that conduct studies and
other services on our behalf. We seek to protect our proprietary technology, in part, by entering into confidentiality agreements, consulting
agreements or other similar agreements with our advisors, employees and consultants prior to beginning research or disclosing proprietary
information. These agreements typically limit the rights of the third parties to use or disclose our confidential information. Despite the
contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases
the risk that such trade secrets become known by our competitors, are intentionally or inadvertently incorporated into the technology of
others or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and
trade secrets and despite our efforts to protect our trade secrets, a competitor’s discovery of our proprietary technology and confidential
information or other unauthorized use or disclosure would impair our competitive position and may have a material adverse effect on our
business, financial condition, results of operations and prospects.
If we are unable to maintain or expand our sales and marketing force, as needed, to adequately address our customers’ and future
partners’ needs, our business may be adversely affected.
We sell our testing products through our own specialized sales force. Our testing products compete in a concentrated specialty market of
autoimmune and autoimmune-related diseases, and utilizing a specialized sales force is integral to our strategy. As such, we believe it is
necessary to maintain a sales force that includes sales representatives with specific technical backgrounds and industry expertise and expect
to continue to evaluate the reach and frequency with rheumatologists, including as we launch our pipeline products. We may be required to
expand our specialized sales force as our company grows. Training of additional sales representatives can be costly and time consuming,
particularly given the level of experience and sophistication we seek in our sales force. If we are unable to effectively retain, train and
integrate additional sales representatives, as needed, it may adversely affect our ability to effectively market and sell our testing products. In
addition, competition for highly specialized sales personnel is intense, and we may not be able to attract and retain personnel or be able to
maintain an efficient and effective sales and marketing force.
Our future sales will depend in large part on our ability to maintain an effective sales force. If we are unsuccessful in this regard, it could
negatively impact our revenue growth and potential profitability.
If we are unable to compete successfully, we may be unable to increase or sustain our revenue or achieve profitability.
Our principal competition for our testing products is traditional methods used by healthcare providers to test patients with CTD-like
symptoms. Such traditional methods include testing for a broad range of diagnostic, immunology and chemistry biomarkers, such as ANA
and anti-dsDNA and serum complement biomarkers, such as C3 and C4. We
40
also face competition from commercial laboratories, such as ARUP Laboratories, Inc.; Laboratory Corporation of America Holdings; the Mayo
Clinic; and Quest Diagnostics Incorporated, all of which have existing infrastructures to support the commercialization of diagnostic services.
Large, multispecialty group medical clinics, health systems and academic medical university-based clinics may provide in-house clinical
laboratories offering autoimmune and autoimmune-related disease testing services. Additionally, we compete against regional clinical
laboratories providing testing in the autoimmune and autoimmune-related disease field, including Rheumatology Diagnostics Laboratories,
Inc. (acquired by Laboratory Corporation of America in June 2020). Other potential competitors include companies that might develop
diagnostic or disease or drug monitoring products, such as AMPEL BioSolutions, LLC; DxTerity Diagnostics Inc.; Genalyte Inc.; Immunovia
AB; Oncimmune plc; Progentec Diagnostics Inc.; and Scipher Medicine Corporation. In the future, we may also face competition from
companies developing new products or technologies.
We believe the principal competitive factors in our target market include: quality and strength of clinical and analytical validation data;
confidence in diagnostic results; sales and marketing capabilities; the extent of reimbursement; inclusion in clinical guidelines; cost-
effectiveness; and ease of use. We rely upon independent sources for phlebotomy to obtain patient samples; interruptions to this capability
could dramatically impact patient access to our tests.
Many of our potential competitors have widespread brand recognition and substantially greater financial, technical and research and
development resources and selling and marketing capabilities than we do. Others may develop products with prices lower than ours that
could be viewed by rheumatologists and payors as functionally equivalent to our solution or offer solutions at prices designed to promote
market penetration, which could force us to lower the list price of our products and affect our ability to achieve profitability. If we are unable to
change clinical practice in a meaningful way or compete successfully against current and future competitors, we may be unable to increase
market acceptance and sales of our products, which could prevent us from increasing our revenue or achieving profitability and could cause
the market price of our common stock to decline.
To compete successfully we must be able to demonstrate, among other things, that our testing products are accurate and cost effective.
Developing new testing products involves a lengthy and complex process, and we may not be able to commercialize on a timely
basis, or at all, other testing products we are developing.
We may not be able to develop testing products with the clinical utility necessary to be useful and commercially successful. There are certain
products for which a commercial launch would trigger additional payment obligations to licensors of the technology. In these cases, if the
economic projections of the product do not outweigh the additional obligations, we may not launch these products. In order to develop and
commercialize testing products, we need to:
•
•
•
•
•
•
expend significant funds to conduct substantial research and development;
conduct successful verification, validation and utility studies;
develop and scale our laboratory processes to accommodate different tests;
achieve and maintain required regulatory certifications, including the hiring of appropriately licensed laboratory personnel;
develop and scale our infrastructure to be able to analyze increasingly large amounts of data; and
build the commercial infrastructure to market and sell new testing products.
Our testing product development process involves a high degree of risk and may take several years. Our testing product development efforts
may fail for many reasons, including:
•
•
•
•
•
failure to identify additional biomarkers to incorporate into our testing products;
failure or sub-optimal performance of the testing product at the research or development stage;
obtaining patient consent inclusive of genetic analysis;
difficulty in accessing archival patient specimens, especially specimens with known clinical results; or
failure of clinical validation, utility and outcome studies to support the effectiveness of the test.
41
Typically, few research and development projects result in commercial products, and success in early clinical studies often is not replicated in
later studies. At any point, we may abandon development of a testing product candidate or we may be required to expend considerable
resources repeating clinical studies, which would adversely affect the timing for generating potential revenue from a new testing product and
our ability to invest in other products in our pipeline.
In addition, as we develop testing products, we may have to make significant investments in product development, marketing and selling
resources. If a clinical validation study fails to demonstrate the prospectively defined endpoints of the study, we might choose to abandon the
development of the testing product or product feature that was the subject of the clinical study, which could harm our business. Additionally,
competitors may develop and commercialize competing products or technologies faster than us or at a lower cost.
Developing new testing products and enhancements to our existing technologies is expensive and time consuming, and there is no
assurance that such activities will result in significant new marketable testing products, enhancements to our current technologies, design
improvements, cost savings, revenue or other expected benefits. If we spend significant resources on research and development and are
unable to generate an adequate return on our investment or divert resources away from other, more attractive growth opportunities, our
business and results of operations may be materially and adversely affected.
If we cannot enter into new clinical study collaborations, our product development and subsequent commercialization could be
delayed.
In the past, we have entered into clinical study collaborations, and our success in the future depends in part on our ability to enter into
additional collaborations with highly regarded institutions. This can be difficult due to internal and external constraints placed on these
organizations. Some organizations may limit the number of collaborations they have with any one company so as to not be perceived as
biased or conflicted. Organizations may also have insufficient administrative and related infrastructure to enable collaborations with many
companies at once, which can extend the time it takes to develop, negotiate and implement a collaboration. Additionally, organizations often
insist on retaining the rights to publish the clinical data resulting from the collaboration. The publication of clinical data in peer-reviewed
medical journals is a crucial step in commercializing and obtaining reimbursement for testing products such as ours, and our inability to
control when and if results are published may delay or limit our ability to derive sufficient revenue from any solution.
We may acquire businesses or assets, form joint ventures or make investments in other companies or technologies that could
harm our operating results, dilute our stockholders’ ownership, increase our debt or cause us to incur significant expense.
As part of our business strategy, we may pursue acquisitions of complementary businesses or assets, as well as technology licensing
arrangements and other strategic transactions or collaborations with third parties. We also may pursue strategic alliances that leverage our
core technology and industry experience to expand our offerings or distribution, make investments in other companies or acquire ownership
rights to therapeutics that are synergistic with our testing products. To date, other than our acquisition of the medical diagnostics division of
Cypress Bioscience, Inc. in 2010, we have not acquired other companies or therapeutics and we have limited experience with respect to the
formation of strategic alliances and joint ventures. If we make any acquisitions, we may not be able to integrate these acquisitions
successfully into our existing business, and we could assume unknown or contingent liabilities. Any future acquisitions by us also could result
in significant write-offs or the incurrence of debt and contingent liabilities, any of which could harm our operating results. Integration of an
acquired company, business or assets also may require management resources that otherwise would be available for ongoing development
of our existing business. We may not identify or complete these transactions in a timely manner, on a cost-effective basis, or at all, and we
may not realize the anticipated benefits of any acquisition, technology license, strategic alliance, joint venture or investment.
To finance any acquisitions or investments, we may choose to issue shares of our stock as consideration, which would dilute the ownership
of our stockholders. If the price of our common stock is low or volatile, we may not be able to acquire other companies for stock. Alternatively,
it may be necessary for us to raise additional funds for these activities through public or private financings or through the issuance of debt.
Additional funds may not be available on terms that are favorable to us, or at all, and any debt financing may involve covenants limiting or
restricting our ability to take certain actions.
Also, the anticipated benefit of any strategic alliance, joint venture or acquisition may not materialize or such strategic alliance, joint venture
or acquisition may be prohibited. In addition, our loan agreement restricts our ability to pursue certain mergers, acquisitions, amalgamations
or consolidations that we may believe to be in our best interest. Additionally, future acquisitions or dispositions could result in potentially
dilutive issuances of our equity
42
securities, the incurrence of debt, contingent liabilities or amortization expenses or write-offs of goodwill, any of which could harm our
financial condition. We cannot predict the number, timing or size of future joint ventures or acquisitions, or the effect that any such
transactions might have on our operating results.
The diagnostic industry is subject to rapidly changing technology, which could make our current and future testing products
obsolete.
Our industry is characterized by rapid technological changes, frequent new product introductions and enhancements and evolving industry
standards. These advances require us to continuously develop our technology and work to develop new solutions to keep pace with evolving
standards of care. Our testing products could become obsolete unless we continually innovate and expand our testing product offerings to
include new clinical applications. If we are unable to develop new testing products or to demonstrate the applicability of our testing products
for other diseases, our sales could decline and our competitive position could be harmed.
Our failure to maintain relationships or build new relationships with key opinion leaders could materially adversely impact our
business and prospects.
Key opinion leaders are able to influence clinical practice by publishing research and determining whether new tests should be integrated
into clinical guidelines. We rely on key opinion leaders early in the development process to help ensure our clinical studies are designed and
executed in a way that clearly demonstrates the benefits of our testing products to healthcare providers and payors. Our failure to maintain or
build new relationships with such key opinion leaders could affect rheumatologist and patient perception of our testing products and result in
a loss of existing and future customers and therefore materially adversely impact our business and prospects.
If we are sued for errors and omissions or professional liability, we could face substantial liabilities that exceed our resources.
The marketing, sale and use of our testing products could lead to liability claims if someone were to allege that any such testing product
failed to perform as it was designed. We may also be subject to liability for errors in the results we provide to rheumatologists or for a
misunderstanding of, or inappropriate reliance upon, the information we provide. We may also be subject to similar types of claims related to
testing products we may develop in the future. Any errors or omissions or professional liability claim could result in substantial damages and
be costly and time consuming for us to defend. Although we maintain professional liability insurance, we cannot assure you that our
insurance would fully protect us from the financial impact of defending against these types of claims or any judgments, fines or settlement
costs arising out of any such claims. Any errors or omissions or professional liability claim brought against us, with or without merit, could
increase our insurance rates or prevent us from securing insurance coverage in the future. Additionally, any product liability lawsuit could
cause injury to our reputation or cause us to suspend sales of our testing products. Similarly, any product liability lawsuit affecting our
partners could also cause injury to our reputation. We may also initiate a correction or removal for one of our testing products, issue a safety
alert or undertake a field action or recall to reduce a risk to health posed by potential failure of our products to perform as designed, which
could lead to increased costs and lead to increased scrutiny by regulatory authorities and our customers regarding the quality and safety of
our testing products and to negative publicity, including safety alerts, press releases or administrative or judicial actions. The occurrence of
any of these events could have an adverse effect on our business and results of operations.
The loss of members of our senior management team or our inability to attract and retain highly skilled scientists, technicians and
salespeople could adversely affect our business.
Our success depends largely on the skills, experience and performance of key members of our executive management team, including John
Aballi, our President and Chief Executive Officer, and others in key management positions. The efforts of each of these persons will be
critical to us as we continue to develop our technologies and test processes and focus on our growth. If we were to lose one or more of these
key employees, we may experience difficulties in competing effectively, developing our technologies and implementing our business strategy.
In addition, our research and development programs and commercial laboratory operations depend on our ability to attract and retain highly
skilled scientists, including licensed clinical laboratory scientists and biostatisticians. We may not be able to attract or retain qualified
scientists and technicians in the future due to the intense competition for qualified personnel among life science businesses, particularly in
Southern California. Because it is expected that there will be a shortage of clinical laboratory scientists in coming years, it may become more
difficult to hire sufficient numbers of qualified personnel. We also face competition from universities and public and private research
institutions in recruiting and retaining highly qualified scientific personnel. Additionally, our success depends on our ability to attract and retain
qualified and highly-specialized salespeople. We may have difficulties locating, recruiting or retaining qualified salespeople, which could
cause a delay or decline in the rate of adoption of
43
our testing products. If we are not able to attract and retain the necessary personnel to accomplish our business objectives, we may
experience constraints that could adversely affect our ability to support our research and development, clinical laboratory and sales efforts.
All of our employees are at-will, which means that either we or the employee may terminate their employment at any time.
If our sole clinical laboratory facility becomes damaged or inoperable, we are required to vacate our existing facility or we are
unable to expand our existing facility as needed, we will be unable to perform our testing services and our business will be
harmed.
We currently derive all of our revenue from tests conducted at a single laboratory facility located in Vista, California. Vista is situated on or
near earthquake fault lines. Our facility and equipment could be harmed or rendered inoperable by natural or man-made disasters which may
be exacerbated due to climate change, including earthquake, fire, flood, power loss, communications failure or terrorism, or public health
crises. In particular, we store all of our flow cytometers, the instrument we use to detect CB-CAPs on cells, at our Vista facility. If all of our
flow cytometers were rendered inoperable simultaneously pursuant to a natural or man-made disaster, we would be unable to perform these
key tests as we do in the ordinary course of our business. The inability to perform the tests contained in our testing products or to reduce the
backlog of analyses that could develop if our facility is inoperable, for even a short period of time, may result in the loss of customers or harm
to our reputation, and we may be unable to regain those customers or repair our reputation in the future. Additionally, we store our bio-
repository of specimens, which were collected in collaboration with leading academic institutions and help us to further validate our testing
products, at our Vista facility. If these specimens were destroyed pursuant to a natural or man-made disaster or otherwise become
unavailable, our ability to develop new testing products may be delayed. Furthermore, our facility and the equipment we use to perform our
research and development work could be unavailable or costly and time-consuming to repair or replace. It would be difficult, time-consuming
and expensive to rebuild our facility or license or transfer our proprietary technology to a third party, particularly in light of the licensure and
accreditation requirements for a commercial laboratory like ours. Even in the unlikely event we are able to find a third party with such
qualifications to enable us to conduct the tests contained in our testing products, we may be unable to negotiate commercially reasonable
terms.
In order to rely on a third party to perform the tests contained in our testing products (even assuming we are able to do so in compliance with
applicable regulations), we would need to engage another facility with established state licensure and CLIA certification under the scope of
which tests could be performed following validation and other required procedures. We cannot assure you that we would be able to find
another CLIA-certified facility willing to comply with the required procedures, that any such facility would be willing to perform the tests
contained in our testing products for us on commercially reasonable terms, or that it would be able to meet our quality standards.
In order to establish additional clinical reference laboratory facilities, we have to spend considerable time and money securing adequate
space, which may include constructing additional facilities, recruiting and training employees, and establishing the additional operational and
administrative infrastructure necessary to support a second facility. We may not be able, or it may take considerable time, to replicate our
testing processes or results in any new or converted facility. Additionally, any new clinical reference laboratory facility opened by us would be
subject to certification under CLIA and licensing by several states, including, as applicable, California and New York, which could take a
significant amount of time and result in delays in our ability to begin operations.
We believe we have the capacity to meet our projected needs for at least the next 12 months, although we may grow at a rate that is faster
than we expect. We may need to further expand our laboratory space in the future. Any future expansion could disrupt laboratory operations,
resulting in an inability to meet customer turnaround time expectations, and could be delayed, resulting in slower realization of laboratory
efficiencies anticipated from the use of the expanded facilities. Adverse consequences resulting from a delay in the laboratory expansion
could harm our relationships with our customers and our reputation, and could affect our ability to generate revenue.
We carry insurance for damage to our property and the disruption of our business, but this insurance may not cover all the risks associated
with damage or disruption to our business, provide coverage in amounts sufficient to cover our potential losses or continue to be available to
us on acceptable terms, if at all.
Our testing process involves the use of sophisticated state-of-the-art equipment that requires precise calibration, and issues
affecting such equipment may delay delivery or impact the quality of the test results to rheumatologists or otherwise adversely
affect our operations.
®
As part of our process of determining CB-CAPs, the key biomarker detection and measurement technology incorporated into our AVISE
Lupus and AVISE CTD products, we utilize a number of flow cytometers that require calibration and performance validation according to the
requirements of the CAP at specified time intervals. While we believe we have implemented appropriate controls and metrics in our
laboratory to meet such requirements, we
®
44
cannot provide any assurance that our instruments will not fall out of specification, in which case we would be required to re-calibrate them.
Failure to timely re-calibrate our instruments could negatively impact the test results, which could result in liability and harm our reputation.
Patient specimens degrade and become unusable generally within 48 hours of collection. Therefore, if we do not have other sufficient
properly functioning flow cytometers due to failure to meet specifications or they otherwise become inoperable, our ability to process patient
specimens in the required timeframe would be compromised and our business could be harmed.
Failure in our information technology, telephone or other systems could significantly disrupt our operations and adversely affect
our business and financial condition.
Information technology and telephone systems are used extensively in virtually all aspects of our business, including laboratory testing,
sales, billing, customer service, logistics and management of medical data. The success of our business depends on the ability to obtain,
process, analyze, maintain and manage this data. Our management relies on our information systems because:
•
•
•
•
•
•
•
•
patient specimens must be received, tracked and processed on a timely basis;
test results must be reported on a timely basis;
billings and collections for all customers must be managed efficiently and accurately;
third-party ancillary billing services require proper tracking and reporting;
pricing and other information related to our services is needed by our sales force and other personnel in a timely manner to conduct
business;
patient-identifiable health information must be securely held and kept confidential;
regulatory compliance requires proper tracking and reporting; and
proper recordkeeping is required for operating our business, managing employee compensation and other personnel matters.
Our business, results of operations and financial condition may be adversely affected if, among other things:
•
•
•
•
•
our information technology, telephone or other systems fail or are interrupted for any extended length of time;
services relating to our information technology, telephone or other systems are not kept current;
our information technology, telephone or other systems do not have the capacity to support expanded operations and increased
levels of business;
data is lost or unable to be restored or processed; or
data is corrupted due to a breach of security.
Despite the precautionary measures we have taken to prevent breakdowns in our information technology, telephone and other systems,
sustained or repeated system failures that interrupt our ability to process test orders, deliver test results or perform testing in a timely manner
or that cause us to inadvertently disclose or lose patient information could adversely affect our business, results of operations and financial
condition.
Security breaches, loss of data and other disruptions to us, our third-party service providers or our partners 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 our reputation.
In the ordinary course of our business, we and our partners, and our respective third-party service providers collect and store sensitive data,
such as PHI (including test results), personally identifiable information and credit card information. We also store business and financial
information, intellectual property, research and development information, trade secrets, and other proprietary and business critical
information, including that of our customers, payors and third-party partners. We manage and maintain our applications and data utilizing a
combination of on-site and vendor-owned systems. We face a number of risks related to our protection of, and our service providers’
protection of, this critical information, including loss of access, unauthorized disclosure and unauthorized access, as well as risks associated
with our ability to identify and audit such events and risks associated with the need to
45
reconstruct any lost or stolen data. In addition, we have limited control over the storage of sensitive data by our third-party partners as well as
risks related to the transfer and sale of de-identified data files to such partners.
The secure processing, storage, maintenance and transmission of this critical information is vital to our operations and business strategy, and
we devote significant resources to protecting such information. Although we take measures to protect sensitive information from unauthorized
access or disclosure, our information technology and infrastructure, and that of our third-party billing and collections provider, may be
vulnerable to attacks by hackers or viruses or otherwise breached due to employee error, malfeasance or other activities. Attacks upon
information technology systems are increasing in their frequency, levels of persistence, sophistication and intensity, and are being conducted
by sophisticated and organized groups and individuals with a wide range of motives and expertise. Additionally, most of our employees have
the ability to work remotely, which may increase the risk of security breaches, loss of data and other disruptions as a consequence of more
employees accessing sensitive and critical information from remote locations. Because the techniques used to obtain unauthorized access
to, or to sabotage, systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate
these techniques or implement adequate preventative measures. We may also experience security breaches that may remain undetected for
an extended period. While we do not believe that we have experienced any such attack or breach, if such an event were to occur, our
networks would be compromised and the information we store on those networks could be accessed by unauthorized parties, publicly
disclosed, lost or stolen. A security breach or privacy violation that leads to unauthorized access, disclosure or modification of, or prevents
access to, patient information, including PHI, could implicate state and federal breach notification laws. Any such access, disclosure or other
loss of information could also result in legal claims or proceedings, and liability under laws that protect the privacy of personal information,
such as HIPAA, as amended by the HITECH Act, and their implementing regulations and similar state data privacy and security laws and
regulations including civil and criminal penalties. Unauthorized access, loss or dissemination could also disrupt our operations, including our
ability to process tests, provide test results, bill payors or patients, process claims and appeals, provide customer assistance services,
conduct research and development activities, collect, process and prepare company financial information, provide information about our
products and other patient and rheumatologist education and outreach efforts through our website and manage the administrative aspects of
our business and could damage our reputation, any of which could adversely affect our business. Any breach could also result in the
compromise of our trade secrets and other proprietary information, which could adversely affect our competitive position.
In addition, the interpretation and application of federal and state consumer, health-related and data protection laws in the United States are
often uncertain, contradictory and in flux. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with
our practices. If so, this could result in government-imposed fines or orders requiring that we change our practices, as well as private
litigation, which could adversely affect our business. Moreover, these laws and their interpretations are constantly evolving and may become
more stringent or inclusive over time. For example, increasing concerns about health information privacy have recently prompted the federal
government to issue guidance taking a newly expansive view of the scope of the laws and regulations that they enforce. Complying with
these various laws could cause us to incur substantial costs or require us to change our business practices, systems and compliance
procedures in a manner adverse to our business.
If we are unable to prevent such security breaches or privacy violations or implement satisfactory remedial measures in connection with
security incidents, we may suffer loss of reputation, financial loss, and civil or criminal fines or other penalties. In addition, these breaches
and other forms of inappropriate access can be difficult to detect, and any delay in identifying them may lead to increased harm of the type
described above.
Our financial condition, commercialization efforts and results of operations has been and may again in the future be adversely
affected by outbreaks of contagious diseases.
Any outbreak of a contagious disease, or other adverse public health developments, could have a material and adverse effect on our
business operations. Such adverse effects could include disruptions or restrictions on the ability of our, our collaborators’, or our suppliers’
personnel to travel, and could result in temporary closures of our facilities or the facilities of our collaborators or suppliers, including our sole
laboratory. While the impact of the COVID-19 pandemic on our business, financial condition, results of operations and cash flows has
subsided, the extent to which COVID-19 will affect our operations in the future will depend on future developments, which are highly
uncertain and cannot be predicted with confidence.
Performance issues, service interruptions or price increases by our shipping carrier could adversely affect our business, results of
operations and financial condition, and harm our reputation and ability to provide testing services on a timely basis.
Expedited, reliable shipping is essential to our operations. We have been utilizing both United Parcel Service and Federal Express
Corporation (Federal Express) for reliable and secure point-to-point transport of patient specimens
46
to our laboratory and enhanced tracking of these patient specimens. Should Federal Express, United Parcel Service, or any other carrier we
may use in the future, encounter delivery performance issues such as loss, damage or destruction of a specimen, it may be difficult to
replace our patient specimens in a timely manner and such occurrences may damage our reputation and lead to decreased utilization from
rheumatologists for our testing services and increased cost and expense to our business. In addition, any significant increase in shipping
time or disruption to delivery service, whether due to bad weather, natural disaster (which may be exacerbated due to climate change), public
health epidemics or pandemics, terrorist attacks or threats, labor strikes, work stoppages or boycotts, or for other reasons, could adversely
affect our ability to receive and process patient specimens on a timely basis.
If we, Federal Express, or United Parcel Service were to terminate our relationship, we would be required to find another party to provide
expedited, reliable point-to-point transport of our patient specimens. There are only a few other providers of such nationwide transport
services, and there can be no assurance that we will be able to enter into arrangements with such other providers on acceptable terms, if at
all. Finding a new provider of transport services would be time-consuming and costly and result in delays in our ability to provide our testing
services. Even if we were to enter into an arrangement with any such provider, there can be no assurance that they will provide the same
level of quality in transport services currently provided to us by Federal Express and United Parcel Service. If any new provider does not
provide, or if Federal Express or United Parcel Service does not continue to provide, the required quality and reliability of transport services
at the same or similar costs, it could materially and adversely affect our business, reputation, results of operations and financial condition.
Inflation could adversely affect our business and financial results.
Inflation increased significantly during 2022 and continued to increase through 2023. The current inflationary environment has resulted in
higher prices, which have impacted our costs incurred to generate revenue from our laboratory testing services, costs to attract and retain
personnel, and other operating costs. The severity and duration of the current inflationary environment remains uncertain and may continue
to impact our financial condition and results of operations. Inflation may continue to adversely affect us by increasing the costs of products,
materials (including reagents and laboratory supplies), and labor needed to operate our business in future periods. Actions by the
government to stimulate the economy may increase the risk of significant inflation, which may have an adverse impact on our business or
financial results. Moreover, we may not be able to pass those costs along in the products we sell. As such, inflationary pressures could have
a material adverse effect on our performance and financial statements.
The failure of financial institutions or transactional counterparties could adversely affect our current and projected business
operations and our financial condition and results of operations.
On March 10, 2023, Silicon Valley Bank (SVB) was closed by the California Department of Financial Protection and Innovation, which
appointed the Federal Deposit Insurance Corporation (FDIC) as receiver. Similarly, on March 12, 2023, Signature Bank and Silvergate
Capital Corp. were each swept into receivership. A statement by the Department of the Treasury, the Federal Reserve and the FDIC stated
that all depositors of SVB would have access to all of their money after only one business day of closure, including funds held in uninsured
deposit accounts. Although we do not have any funds deposited with SVB and Signature Bank, we regularly maintain cash balances with
other financial institutions in excess of the FDIC insurance limit. A failure of a depository institution to return deposits could impact access to
our invested cash or cash equivalents and could adversely impact our operating liquidity and financial performance.
Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.
Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the Code), if a corporation undergoes an “ownership
change” (generally defined as a greater than 50 percentage-point change (by value) in its equity ownership by “5-percent shareholders,” as
defined in the Code, over a rolling three-year period), the corporation’s ability to use its pre-change net operating loss (NOL), carryforwards
and other pre-change tax attributes to offset its post-change federal taxable income and taxes, as applicable, may be limited. We previously
completed a study to assess whether an ownership change, as defined by Section 382 of the Code, had occurred from our formation through
December 31, 2019. Based upon this study, we determined that ownership changes had occurred in 2003, 2008, 2012, 2017 and 2019, and
that our ability to use a significant portion of our NOL carryforwards is subject to limitation under Section 382 of the Code as a result of a prior
ownership change. If we undergo an ownership change as a result of subsequent shifts in our stock ownership, our ability to utilize our NOL
carryforwards and other pre-change tax attributes could be further limited by Sections 382 and 383 of the Code. Similar provisions of state
tax law may also apply. In addition, federal NOL carryforwards generated in periods after December 31, 2017, may be carried forward
indefinitely but, in taxable years beginning after December 31, 2020, may only be used to offset 80% of our taxable income. As a result of the
foregoing, if we earn net taxable income,
47
our ability to use NOL carryforwards and other tax attributes to offset taxable income and taxes, as applicable, may be limited.
Our term loan contains restrictions that limit our flexibility in operating our business, and if we fail to comply with the covenants
and other obligations under our loan agreement, the lenders may be able to accelerate amounts owed under the facility and may
foreclose upon the assets securing our obligations.
In September 2017, we entered into the loan and security agreement (the 2017 Term Loan) with Innovatus Life Sciences Lending Fund I, LP
(Innovatus), which we subsequently amended in November 2019, November 2021 and April 2023 (the Amended Loan Agreement). The
Amended Loan Agreement is collateralized by substantially all of our personal property, including our intellectual property. The Amended
Loan Agreement also subjects us to certain affirmative and negative covenants, including limitations on our ability to transfer or dispose of
assets, merge with or acquire other companies, make investments, pay dividends, incur additional indebtedness and liens and conduct
transactions with affiliates. We are also subject to certain covenants that require us to maintain a minimum liquidity of at least $2.0 million,
achieve certain minimum amounts of annual revenue, as measured on a rolling twelve-month basis, periodically deliver financial statements
to Innovatus with an unqualified opinion (including no “going concern”) from our independent certified public accounting firm, and are
required under certain conditions to make mandatory prepayments of outstanding principal. As a result of these covenants, we have certain
limitations on the manner in which we can conduct our business, and we may be restricted from engaging in favorable business activities or
financing future operations or capital needs until our current debt obligations are paid in full or we obtain the consent of Innovatus, which we
may not be able to obtain. As of December 31, 2023, there was $15.0 million in principal outstanding under the term loan and an additional
$3.2 million outstanding representing interest payable in-kind by adding the paid in-kind interest amount to the outstanding principal balance
of the term loans. Under the Amended Loan Agreement, we are required to repay any outstanding principal and capitalized interest in
monthly installments over a ten-month period commencing on April 1, 2026. At December 31, 2023, we were in compliance with all
covenants of the Amended Loan Agreement. We cannot be certain that we will be able to generate sufficient cash flow or revenue to meet
the financial covenants or pay the principal and accrued interest on our debt.
In addition, upon the occurrence of an event of default, Innovatus, among other things, can declare all indebtedness due and payable
immediately, which would adversely impact our liquidity and reduce the availability of our cash flows to fund working capital needs, capital
expenditures and other general corporate purposes. An event of default includes, but is not limited to, our failure to pay any amount due and
payable under the Amended Loan Agreement, the occurrence of a material adverse change in our business as defined in the Amended Loan
Agreement, our breach of any representation or warranty in the Amended Loan Agreement, our breach of any covenant in the Amended
Loan Agreement (subject to a cure period in some cases), a change in control as defined in the Amended Loan Agreement, our default on
any debt payments to a third party in an amount exceeding $0.5 million or any voluntary or involuntary insolvency proceeding. If an event of
default occurs and we are unable to repay amounts due under the Amended Loan Agreement, Innovatus could foreclose on substantially all
of our personal property, including our intellectual property. We cannot be certain that future working capital, borrowings or equity financings
will be available to repay or refinance our debt to Innovatus or any other debt we may incur in the future.
We may require substantial additional capital to finance our planned operations, which may not be available to us on acceptable
terms or at all. Our failure to obtain additional financing when needed on acceptable terms, or at all, could force us to delay, limit,
reduce or eliminate our product development programs, commercialization efforts or other operations.
We believe, based on our current plan, that our current cash and cash equivalents and anticipated future revenue, will be sufficient to meet
our anticipated cash requirements for at least the next 12 months. We have based this estimate on assumptions that may prove to be wrong,
and we could use our capital resources sooner than we currently expect. Our operating plans and other demands on our cash resources may
change as a result of many factors currently unknown to us and we may need to seek additional funds sooner than planned, through public
or private equity or debt financings or other sources, such as strategic collaborations. If our available cash balances and anticipated future
revenue are insufficient to satisfy our liquidity requirements, including because of lower demand for our testing products or lower-than-
expected rates of reimbursement from commercial payors and government payors, or other risks described in this “Risk Factors” section, we
may seek to raise additional capital through equity offerings, debt financings, collaborations or licensing arrangements.
On November 17, 2023, we filed a shelf registration statement on Form S-3, as amended by Amendment No. 1 to Form S-3 filed on
November 27, 2023, that provides for aggregate offerings of up to $150.0 million of our securities subject to various limitations. We filed a
prospectus on November 29, 2023 pursuant to this registration statement, registering sales of our common stock in an amount not to exceed
$50.0 million, pursuant to a sales agreement by
48
and between us and Cowen and Company, LLC (TD Cowen), as amended by Amendment No. 1 to Sales Agreement dated November 17,
2023 (the Amended Sales Agreement). Using a shelf registration statement to raise capital generally takes less time and is less expensive
than other means, such as conducting an offering under a registration statement on Form S-1 and companies may be able to receive more
favorable terms by raising capital pursuant to a shelf registration statement on Form S-3. Our ability to raise capital under our current shelf
registration statement (and any future registration statement on Form S-3) is, and may again in the future be, limited by, among other things,
current and future SEC rules and regulations impacting the eligibility of smaller companies to use Form S-3 without restrictions. As of the
date of this Annual Report, we are subject to the "baby shelf rule" because the market value of our outstanding shares of common stock held
by non-affiliates, or public float, was less than $75.0 million as of the date of this Annual Report. As a result, for sales following the date of
this Annual Report and until we again have a public float with a value in excess of $75.0 million, if ever, we will be unable to use our shelf
registration statement on Form S-3 or the Amended Sales Agreement to raise additional funds to the extent the aggregate market value of
securities sold by us or on our behalf pursuant to Instruction I.B.6. of Form S-3 during the 12 calendar months immediately prior to, and
including, any intended sale does not exceed one-third of the aggregate market value of our public float, calculated in accordance with the
instructions to Form S-3.
In the case of the incurrence of further indebtedness, the Amended Loan Agreement, subject to certain customary exceptions, restricts our
ability to incur additional indebtedness or encumber any of our property without the prior consent of Innovatus. Under the Amended Loan
Agreement, we are required to make monthly interest payments at a rate equal to the sum (the Basic Rate) of (a) the greater of 8.0% or The
Wall Street Journal prime rate (the Prime Rate), plus (b) 2.0% (provided that 1.5% of the Basic Rate is payable in-kind by adding the amount
to the outstanding principal balance of the term loans). We may also consider raising additional capital in the future to expand our business,
pursue strategic investments, take advantage of financing opportunities, or for other reasons. In addition, we may seek additional capital due
to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating
plans. The timing and amounts of our future capital requirements are difficult to forecast and will depend on numerous factors, including: our
ability to maintain and grow sales of our testing products, as well as the costs associated with conducting clinical studies to demonstrate the
utility of our testing products and support reimbursement efforts; fluctuations in working capital; the costs to expand our sales and marketing
capabilities; the costs of developing our product pipeline, including the costs associated with conducting our ongoing and future validation
studies; the additional costs we may incur as a result of operating as a public company and the extent to which we in-license, acquire or
invest in complementary businesses or products.
Additional funding may not be available to us on acceptable terms, or at all. If we raise funds by issuing equity securities, dilution to our
stockholders could result, and the market price of our common stock could decline. Any equity securities issued also may provide for rights,
preferences or privileges senior to those of holders of our common stock. The incurrence of additional indebtedness or the issuance of
certain equity securities could result in increased fixed payment obligations and could also result in restrictive covenants (similar to our
current obligations pursuant to the Amended Loan Agreement), such as limitations on our ability to incur additional debt or issue additional
equity, limitations on our ability to acquire or license intellectual property rights, and other operating restrictions that could adversely affect our
ability to conduct our business. In addition, our Amended Loan Agreement restricts our ability to incur additional indebtedness or encumber
any of our property without the prior consent of Innovatus, subject to certain exceptions. In the event that we enter into collaborations or
licensing arrangements to raise capital, we may be required to accept unfavorable terms. These agreements may require that we relinquish
or license to a third party on unfavorable terms our rights to technologies or product candidates that we otherwise would seek to develop or
commercialize ourselves or reserve certain opportunities for future potential arrangements when we might be able to achieve more favorable
terms. If we are not able to secure additional funding when needed, we may have to delay, reduce the scope of or eliminate one or more
research and development programs or selling and marketing initiatives. In addition, we may have to work with a partner on one or more of
our testing products or market development programs, which could lower the economic value of those products or programs to our company.
We are an emerging growth company and a smaller reporting company, and the reduced disclosure requirements applicable to
emerging growth companies and smaller reporting companies may make our common stock less attractive to investors.
We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the JOBS Act) and may remain an
emerging growth company until the last day of the fiscal year following the fifth anniversary of the completion of our IPO, or December 31,
2024. However, if certain events occur prior to the end of such five-year period, including if we become a “large accelerated filer,” our annual
gross revenue exceeds $1.235 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be
an emerging growth company prior to the end of such five-year period. For so long as we remain an emerging growth company,
49
we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are
not emerging growth companies. These exemptions include:
•
•
•
•
•
being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim condensed
financial statements, with correspondingly reduced “Management’s discussion and analysis of financial condition and results of
operations” disclosure;
not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial
reporting;
not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board
regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and
the financial statements;
reduced disclosure obligations regarding executive compensation; and
exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any
golden parachute payments not previously approved.
We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our
common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be
reduced or more volatile. In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition
period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of these
accounting standards until they would otherwise apply to private companies. We have elected to avail ourselves of this exemption and,
therefore, we may not be subject to the same implementation timing for new or revised accounting standards as other public companies that
are not emerging growth companies, which may make comparison of our financials to those of other public companies more difficult.
We are also a “smaller reporting company” as defined in the Exchange Act. We may continue to be a smaller reporting company even after
we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting
companies and will be able to take advantage of these scaled disclosures for so long as our voting and non-voting common stock held by
non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter, or our annual revenue is less than
$100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than
$700.0 million measured on the last business day of our second fiscal quarter.
Risks Related to Regulatory and Compliance Matters
Healthcare policy changes, including recently enacted and proposed new legislation reforming the U.S. healthcare system, could
cause significant harm to our business, operations and financial condition.
The ACA made a number of substantial changes to the way healthcare is financed both by governmental and commercial payors. The ACA
also introduced mechanisms to reduce the per capita rate of growth in Medicare spending if expenditures exceed certain targets. Any such
reductions could affect reimbursement payments for our tests.
In April 2014, Congress passed PAMA, which included substantial changes to the way in which clinical laboratory services are paid under the
CLFS. Under PAMA, certain clinical laboratories are required to periodically report to CMS private payor payment rates and volumes for their
tests, and laboratories that fail to report the required payment information may be subject to substantial civil monetary penalties. Medicare
reimbursement for CDLTs is based on the weighted-median of the payments made by private payors for these tests, rendering private payor
payment levels even more significant than in the past. As a result, future Medicare payments may fluctuate more often and become subject
to the willingness of private payors to recognize the value of diagnostic tests generally and any given test individually. The impact of this
payment system on rates for our tests, including any current or future tests we may develop, is uncertain.
We cannot predict whether or when these or other recently enacted healthcare initiatives will be implemented at the federal or state level or
how any such legislation or regulation may affect us. For instance, the payment reductions imposed by the ACA and the changes to
reimbursement amounts paid by Medicare for tests such as ours based on the procedure set forth in PAMA, could limit the prices we will be
able to charge or the amount of available reimbursement for our tests, which would reduce our revenue. Additionally, these healthcare laws,
regulations and policies could be amended or additional healthcare initiatives could be implemented in the future.
50
Further, the impact on our business of the expansion of the federal and state governments’ role in the U.S. healthcare industry generally,
including the social, governmental and other pressures to reduce healthcare costs while expanding individual benefits, is uncertain. Any
future changes or initiatives could have a materially adverse effect on our business, financial condition, results of operations and cash flows.
Complying with numerous regulations pertaining to our business is an expensive and time-consuming process, and any failure to
comply could result in substantial penalties.
We are subject to CLIA, a federal law that regulates clinical laboratories that perform testing on specimens derived from humans for the
purpose of providing information for the diagnosis, prevention or treatment of disease. CLIA regulations mandate specific standards in the
areas of personnel qualifications, administration and participation in proficiency testing, patient test management, quality control, quality
assurance and inspections. We have a current certificate of accreditation under CLIA because we are accredited to perform testing by CAP.
To renew this certificate, we are subject to survey and inspection every two years. Moreover, inspectors from CMS or CAP may make
random inspections of our clinical reference laboratory.
Although we are required to hold a certificate of accreditation or compliance under CLIA that allows us to perform high complexity testing, we
are not required to hold a certificate of accreditation through CAP. We could alternatively maintain a certificate of accreditation from another
accrediting organization or a certificate of compliance through inspection by surveyors acting on behalf of the CLIA program. If our
accreditation under CAP were to terminate, either voluntarily or involuntarily, we would need to convert our certification under CLIA to a
certificate of compliance (or to a certificate of accreditation with another accreditation organization) in order to maintain our ability to perform
clinical testing and to continue commercial operations. Whether we would be able to successfully maintain operations through either of these
alternatives would depend upon the facts and circumstances surrounding termination of our CAP accreditation, such as whether any
deficiencies were identified by CAP as the basis for termination and, if so, whether these were addressed to the satisfaction of the surveyors
for the CLIA program (or another accrediting organization).
The failure to comply with CLIA requirements can result in enforcement actions, including the revocation, suspension, or limitation of our
CLIA certificate of accreditation, as well as a directed plan of correction, state on-site monitoring, civil money penalties, civil injunctive suit
and/or criminal penalties. We must maintain CLIA compliance and certification to be eligible to bill for tests provided to Medicare
beneficiaries. If we were to be found out of compliance with CLIA program requirements and subjected to sanctions, our business and
reputation could be harmed. Even if it were possible for us to bring our laboratory back into compliance, we could incur significant expenses
and potentially lose revenue in doing so.
We are also required to maintain a license to conduct testing in California. California laws establish standards for day-to-day operation of our
clinical reference laboratory, including the training and skills required of personnel and quality control. In addition, our clinical reference
laboratory is licensed on a product-specific basis by New York as an out of state laboratory and our testing products, as LDTs, must be
approved by the NYSDOH on a product-by-product basis before they are offered in New York. We are also subject to periodic inspection by
the NYSDOH and required to demonstrate ongoing compliance with NYSDOH regulations and standards. To the extent NYSDOH identified
any non-compliance and we are unable to implement satisfactory corrective actions to remedy such non-compliance, the State of New York
could withdraw approval for our testing products. New York law also mandates proficiency testing for laboratories licensed under New York
state law, regardless of whether or not such laboratories are located in New York. Moreover, several other states require that we hold
licenses to test specimens from patients in those states. Other states may have similar requirements or may adopt similar requirements in
the future. Although we have obtained licenses from states where we believe we are required to be licensed, we may become aware of other
states that require out-of-state laboratories to obtain licensure in order to accept specimens from the state, and it is possible that other states
currently have such requirements or will have such requirements in the future.
If we were to lose our CLIA accreditation or California license, whether as a result of a revocation, suspension or limitation, we would no
longer be able to sell our testing products, which would limit our revenue and harm our business. If we were to lose our license or fail to
obtain or maintain NYSDOH approval for our laboratory developed tests in New York or if we were to lose our license in other states where
we are required to hold licenses, we would not be able to test specimens from those states, which would limit our revenue.
We conduct business in a heavily regulated industry. Complying with the numerous statutes and regulations pertaining to our
business is expensive and time-consuming, and any failure by us, our consultants or commercial partners to comply could result
in substantial penalties.
51
Our industry and our operations are heavily regulated by various federal, state, local and foreign laws and regulations, and the regulatory
environment in which we operate could change significantly and adversely in the future. These laws and regulations currently include, among
others:
• CLIA’s and CAP’s regulation of our laboratory activities;
•
•
FDA laws and regulations, including but not limited to requirements for offering LDTs;
federal and state laws and standards affecting reimbursement by government payors, including certain coding requirements to obtain
reimbursement and certain payment mechanisms for clinical laboratory services resulting from PAMA;
• HIPAA and HITECH, which establish comprehensive federal standards with respect to the privacy and security of PHI, and
requirements for the use of certain standardized electronic transactions with respect to transmission of such information, as well as
similar laws protecting other types of personal information;
•
•
•
•
•
•
•
•
•
•
•
•
state laws governing the maintenance of personally identifiable information of state residents, including medical information, and
which impose varying breach notification requirements, some of which allow private rights of action by individuals for violations and
also impose penalties for such violations;
the federal Anti-Kickback Statute, which generally prohibits knowingly and willfully offering, paying, soliciting or receiving
remuneration, directly or indirectly, in return for or to induce a person to refer to an individual any good, facility, item or service that is
reimbursable under a federal healthcare program;
the federal Stark Law, which generally prohibits a physician from making a referral for certain designated health services covered by
Medicare or Medicaid, 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 False Claims Act, which imposes civil penalties, and provides for civil whistleblower or qui tam actions, against individuals
or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or
fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government;
the federal Civil Monetary Penalties Law, which generally prohibits, among other things, the offering or transfer of remuneration to a
Medicare or Medicaid beneficiary if it is likely to influence the beneficiary’s selection of a particular provider, practitioner or supplier of
services reimbursable by Medicare or Medicaid;
EKRA, which imposes criminal penalties for knowing and 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
(among other healthcare services) covered by healthcare benefit programs (including commercial insurers) unless a specific
exception applies;
the ACA, which, among other things, establishes a requirement for providers and suppliers to report and return any overpayments
received from the Medicare and Medicaid programs;
other federal and state fraud and abuse laws, such as anti-kickback laws, prohibitions on self-referral, fee-splitting restrictions,
insurance fraud laws, anti-markup laws, prohibitions on the provision of tests at no or discounted cost to induce physician or patient
adoption and false claims acts, some of which may extend to services reimbursable by any third-party payor, including private
payors;
the prohibition on reassignment of Medicare claims and other Medicare and Medicaid billing and coverage requirements;
state laws that prohibit other specified healthcare practices, such as billing physicians for tests that they order, waiving coinsurance,
copayments, deductibles and other amounts owed by patients, business corporations practicing medicine or employing or engaging
physicians to practice medicine and billing a state Medicaid program at a price that is higher than what is charged to one or more
other payors;
the FCPA, and applicable foreign anti-bribery laws;
federal, state and local regulations relating to the handling and disposal of regulated medical waste, hazardous waste and
biohazardous waste and workplace safety for healthcare employees;
52
•
•
laws and regulations relating to health and safety, labor and employment, public reporting, taxation and other areas applicable to
businesses generally, all of which are subject to change, including, for example, the significant changes to the taxation of business
entities were enacted in December 2017; and
similar foreign laws and regulations that apply to us in the countries in which we operate or may operate in the future.
Any future growth of our business, including, in particular, continued reliance on consultants, commercial partners and other third parties,
may increase the potential for violating these laws. In some cases, our risk of violating these or other laws and regulations is further
increased because of the lack of their complete interpretation by applicable regulatory authorities or courts, and their provisions are thus
open to a variety of interpretations.
We have adopted policies and procedures designed to comply with these laws and regulations and, in the ordinary course of our business,
we conduct internal reviews of our compliance with these laws. Our compliance is also subject to review by applicable government agencies.
However, these laws and regulations are subject to change and additional interpretation and guidance from regulatory authorities. For
instance, in April 2022, the HHS OIG issued a new advisory opinion indicating that a particular clinical laboratory’s practice of contracting with
hospitals for the collection of samples for testing could, based on the facts provided and assuming the requisite intent, be a violation of the
federal Anti-Kickback Statute. If this Advisory Opinion ultimately limits our ability to collect samples in a hospital setting, we may be required
to contract for sample collection with other collection sites or sources, such as mobile phlebotomists, that could be more expensive and less
convenient for patients, which could adversely affect both demand for our tests and the margins and profitability of our tests.
Given the complexity of these existing and changing rules and regulations, it is not always possible to identify and deter misconduct by
employees, distributors, consultants and commercial partners and the precautions we take to detect and prevent this activity may not be
effective in controlling unknown or unmanaged risks or losses or in protecting us from government investigations or other actions or lawsuits
stemming from a failure to comply with applicable laws or regulations. Additionally, we are subject to the risk that a person or government
could allege such fraud or other misconduct, even if none occurred. For additional information see the risk factor below entitled “We have
previously and may again in the future be required to modify our business practices, pay fines, incur significant expenses or experience
losses due to litigation or governmental investigations.” Any action brought against us for violation of these or other laws or regulations, even
if we successfully defend against it, could cause us to incur significant legal expenses, divert our management’s attention from the operation
of our business and harm our reputation. If our operations, including the conduct of our employees, consultants and commercial partners, are
found to be in violation of any of these laws and regulations, we may be subject to applicable penalties associated with the violation,
including administrative, civil and criminal penalties, damages, fines, individual imprisonment, exclusion from participation in federal
healthcare programs, refunding of payments received by us and curtailment or cessation of our operations. Any of these consequences could
seriously harm our business and our financial results.
It is possible that some of our business activities could be subject to challenge under one or more of such laws. Such a challenge, regardless
of the outcome, could have a material adverse effect on our business, business relationships, reputation, financial condition and results of
operations. Although an effective compliance program can mitigate the risk of investigation and prosecution for violations of these laws, the
risks cannot be entirely eliminated. Any action against us for violation of these laws, even if we successfully defend against it, could cause us
to incur significant legal expenses and divert our management’s attention from the operation of our business. Moreover, achieving and
sustaining compliance with these laws may prove costly. If we or our operations, or any of the rheumatologists or entities with whom we do
business are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be
subject to significant penalties, including administrative, civil and/or criminal penalties, damages, fines, disgorgement, individual
imprisonment, exclusion from participation in U.S. federal or state healthcare programs, such as Medicare and Medicaid, and similar
programs outside the United States, a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these
laws, and the curtailment or restructuring of our operations, any of which could materially adversely affect our ability to operate our business
and our financial results. To the extent that any of our testing products are sold in a foreign country, we may be subject to similar foreign laws
and regulations, which may include, for instance, applicable post-marketing requirements, including safety surveillance, anti-fraud and abuse
laws, and implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals.
If we use hazardous materials in a manner that causes contamination or injury, we could be liable for resulting damages.
53
We are subject to federal, state and local laws, rules and regulations governing the use, discharge, storage, handling and disposal of
biological material, chemicals and waste. 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, remediation costs and any related penalties or fines, and any liability could exceed our resources or any applicable insurance
coverage we may have. The cost of compliance with these laws and regulations may become significant, and our failure to comply may result
in substantial fines or other consequences, either of which could negatively affect our operating results.
We have previously and may again in the future be required to modify our business practices, pay fines, incur significant expenses
or experience losses due to litigation or governmental investigations.
From time to time and in the ordinary course of our business, we have been and may be subject to litigation or governmental investigation on
a variety of matters in the United States or foreign jurisdictions, including, without limitation, regulatory, intellectual property, product liability,
antitrust, consumer, false claims, whistleblower, qui tam, privacy, anti-kickback, anti-bribery, environmental, commercial, securities and
employment litigation and claims and other legal proceedings that may arise from the conduct of our business. Our activities relating to our
products and services are subject to extensive regulation in the United States and foreign jurisdictions. Like many companies in our industry,
we have in the ordinary course of business received inquiries, subpoenas, civil investigative demands, and other types of information
requests from government authorities. In addition, any litigation or government investigation generally, diverts the attention of our
management team and resources from our core business and limits the time and attention of our management team otherwise available to
devote to our business. Government investigation and litigation in general may cause us to incur significant expenses, to experience
significant losses, and, as a result of such matters, we may also be required to materially alter the conduct of our operations or pay significant
penalties. For example, pursuant to a settlement agreement, we made a single lump-sum remittance to the government in the amount of
$0.7 million plus interest in October 2023, the U.S. Attorney’s Office dismissed this “covered conduct” in the qui tam with prejudice, while
non-covered conduct was dismissed without prejudice. In November 2023, the complaint was unsealed and served on Exagen. Exagen filed
a motion to dismiss the complaint. In February 2024, the relator filed a motion for leave to amend the complaint. Exagen opposed this
motion, and all motions are still pending. The Company intends to vigorously defend against the claims being asserted in the complaint.
Any of these circumstances may adversely affect our business, prospects, reputation and results of operations.
We are subject to U.S. and certain foreign export and import controls, sanctions, embargoes, anti-corruption laws and anti-money
laundering laws and regulations. Compliance with these legal standards could impair our ability to compete in domestic and
international markets. We can face criminal liability and other serious consequences for violations, which can harm our business.
We are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs
regulations, various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets
Controls, the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, and other
state and national anti-bribery and anti-money laundering laws in the countries in which we conduct activities. Anti-corruption laws are
interpreted broadly and prohibit companies and their employees, agents, contractors and other collaborators from authorizing, promising,
offering, or providing, directly or indirectly, improper payments or anything else of value to recipients in the public or private sector. We may
engage third parties to sell our testing products outside the United States, to conduct clinical trials, and/or to obtain necessary permits,
licenses, patent registrations and other regulatory approvals. We have direct or indirect interactions with officials and employees of
government agencies or government-affiliated hospitals, universities and other organizations. We can be held liable for the corrupt or other
illegal activities of our employees, agents, contractors, and other collaborators, even if we do not explicitly authorize or have actual
knowledge of such activities. Any violations of the laws and regulations described above may result in substantial civil and criminal fines and
penalties, imprisonment, the loss of export or import privileges, debarment, tax reassessments, breach of contract and fraud litigation,
reputational harm and other consequences.
The FDA may disagree with our assessment that our AVISE test products and any other tests we may develop are LDTs and
determine that such test products are medical devices subject to the FDCA and FDA regulations.
®
The FDA regulates any diagnostic test that meets the definition of a medical device, except under specific, narrow circumstances. The FDCA
defines a medical device as “an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related
article, including a component part, or accessory which is , among other things: intended for use in the diagnosis of disease or other
conditions, or in the cure, mitigation,
54
treatment, or prevention of disease, in man or other animals and which does not achieve its primary intended purposes through chemical
action within or on the body of man or other animals and which is not dependent upon being metabolized for the achievement of any of its
primary intended purposes.” By this definition, in vitro reagents and diagnostic tests are considered medical devices. Specifically, the FDA
defines an IVD as “reagents, instruments, and systems intended for use in the diagnosis of disease or other conditions, including a
determination of the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae.” Therefore, the FDA generally
considers diagnostic testing products to be IVDs subject to the agency’s regulatory requirements for IVDs. However, the FDA has generally
exercised its enforcement discretion and not enforced applicable regulations with respect to LDTs, which are IVDs that are designed,
manufactured, and used within a single high-complexity CLIA-certified laboratory. We believe that all of our AVISE test products are LDTs,
as are our near-term pipeline candidate tests.
®
®
®
If the FDA were to disagree with our conclusion that our AVISE test products fall within the scope of the agency’s LDT definition and
determines that the AVISE tests are thus subject to FDA’s medical device authorities and implementing regulations, we would become
subject to extensive regulatory requirements and may be required to stop selling our existing tests or refrain from launching any other tests
we may develop. In particular, the FDA may require us to obtain PMAs or another type of device marketing authorization in order for us to
commercialize our AVISE tests. The premarket review process for diagnostic testing products can be lengthy, expensive, time-consuming,
and unpredictable. As part of the process to prepare regulatory submissions for FDA review, we may be required to conduct formal clinical
trials before applying for commercial marketing authorization. Performing additional, new nonclinical studies or clinical trials in order to obtain
product approval from the FDA, if any were to become necessary, would take a significant amount of time and would substantially delay our
ability to commercialize our AVISE tests, all of which would adversely impact our business.
®
®
While we believe that we are currently in material compliance with applicable laws and regulations as historically enforced by the FDA with
respect to LDTs, we cannot assure you that the FDA will agree with our determination. Any finding by the FDA or another regulatory authority
that we have violated these laws and regulations, or a public announcement that we are being investigated for possible violations, could
adversely affect our business, prospects, results of operations or financial condition.
The FDA may finalize its rulemaking to regulate LDTs or Congress may take action to reform the current legal requirements
applicable to LDTs, and in either case, we may become subject to extensive regulatory requirements and may be required to
conduct additional clinical trials prior to continuing to sell our existing tests or launching any other tests we may develop, which
may increase the cost of conducting, or otherwise harm, our business.
®
We currently market our AVISE tests as LDTs and may, in the future, market other tests as LDTs. Although historically the FDA has applied
a policy of enforcement discretion with respect to LDTs whereby the FDA does not generally actively enforce its regulatory requirements for
such tests, in October 2023, the FDA issued a proposed rule to regulate LDTs under the current medical device framework. The agency’s
proposal also includes a plan to phase out its current enforcement discretion policy over several years. This FDA rulemaking was initiated
after years of failed congressional attempts to harmonize the regulatory paradigms applicable to LDTs and other in vitro diagnostic tests, as
discussed further below. The likelihood of the FDA finalizing the proposed rule following a public comment period, as well as potential
litigation challenging its authority to take such action, is uncertain at this time as stakeholders continue to press for a comprehensive
legislative solution instead of administrative agency action.
If there are changes in FDA regulations or legislative authorities such that the agency begins to exercise oversight over LDTs, or if the FDA
disagrees that our marketed tests are within the scope of its criteria used for defining LDTs, we may become subject to extensive regulatory
requirements and may be required to stop selling our existing tests or launching any other tests we may develop and to conduct additional
clinical trials or take other actions prior to continuing to market our tests. If the FDA allows our tests to remain on the market but there is
uncertainty about our tests, if they are labeled investigational by the FDA or if labeling claims the FDA allows us to make do not include the
claims necessary or desirable for successful commercialization, orders from healthcare providers or reimbursement for our tests may decline.
In addition, as noted above, Congress had been working on legislation to create an LDT and IVD, regulatory framework that would be
separate and distinct from the existing medical device regulatory framework. Reform legislation called the VALID Act garnered bipartisan and
bicameral support in recent years but failed to move out of committee during the last congressional session. As drafted and re-introduced for
consideration by the current Congress, the VALID Act would codify the term IVCT to create a new medical product category separate from
medical devices to include products currently regulated as IVDs as well as LDTs, among other provisions. The VALID Act would also create a
new system for laboratories to use to submit their tests electronically to the FDA for
55
approval, which is aimed at reducing the amount of time it would take for the agency to approve such tests and establish a new program to
expedite the development of diagnostic tests that can be used to address a current unmet need for patients. The FDA’s October 2023
publication of an LDT proposed rule that would apply the existing medical device framework to laboratory-developed products has renewed
stakeholder calls for a more targeted approach to modernizing the federal government’s oversight of clinical diagnostic tests. It remains
possible that congressional action in this area could displace the need for the FDA to complete its recently proposed rulemaking.
If Congress were to pass the VALID Act or any other legislation applicable to the FDA’s regulation of LDTs, or if the FDA were to successfully
promulgate new regulations for such products through the recently initiated notice-and-comment rulemaking or a future rulemaking
proceeding, we will likely be subject to increased regulatory burdens such as registration and listing requirements, adverse event reporting
requirements and quality control requirements. Any legislation or formal FDA regulatory framework affecting LDTs is also likely to have
premarket application requirements prohibiting commercialization without FDA authorization and controls regarding modification to the tests
that may require further FDA submissions. The premarket review process can be lengthy, expensive, time-consuming and unpredictable.
Further, obtaining premarket clearance may involve, among other things, successfully completing clinical trials, which require significant time
and cash resources and are subject to a high degree of risk, including risks of experiencing delays, failing to complete the trial or obtaining
unexpected or negative results. If we are required to obtain premarket clearance or approval and/or conduct premarket clinical trials, our
development costs could significantly increase, marketing of any new tests we may develop may be delayed, and sales of our existing tests
could be interrupted or stopped. Any of these outcomes could reduce our revenue or increase our costs and materially adversely affect our
business, prospects, results of operations or financial condition.
The outcome and ultimate impact on our business of any changes to the federal government’s regulation of LDTs is difficult to predict. Failure
to comply with any applicable FDA requirements could trigger a range of enforcement actions, including warning letters, fines, penalties,
suspension of operations, product recalls or seizures, denial of applications for clearance or approval, injunctions and other civil or criminal
sanctions, which could have a material and adverse effect upon our business, operating results and financial condition.
Furthermore, should it be required in the future, we cannot be sure that our AVISE tests, or any new tests that we may develop, will be
reviewed and authorized for marketing by the FDA in a timely or cost-effective manner, if authorized at all. Even if such tests are authorized
for marketing by the FDA, the agency could limit the test’s indications for use, which may significantly limit the market for that product and
may adversely affect our business and financial condition.
®
The FTC and/or state enforcement or regulatory agencies may object to the methods and materials we use to promote our tests
and initiate enforcement against us, which could adversely affect our business and financial condition.
The FTC and/or state enforcement or regulatory agencies (including but not limited to the offices of state attorneys general) may object to the
materials and methods we use to promote 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 FTC may include, among
others, injunctions, civil penalties and equitable monetary relief.
Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, standards and other
requirements could adversely affect our business, results of operations and financial condition.
Any failure or perceived failure by us to comply with federal or state laws or regulations, our internal policies and procedures or our contracts
governing our use and disclosures of personal information could result in negative publicity, government investigations and enforcement
actions including significant penalties, claims by third parties, and damage to our reputation, any of which could have a material adverse
effect on our operations, financial performance and business.
Failure to comply with HIPAA, the HITECH Act, their implementing regulations and similar comparable state laws and regulations affecting
the transmission, security and privacy of health information could result in significant penalties.
Numerous federal, state and foreign laws and regulations, including HIPAA and the HITECH Act, govern the collection, dissemination,
disclosure, security, use and confidentiality of individually identifiable health information health-related and other personal information. HIPAA
and the HITECH Act require us to comply with standards for the use and disclosure of PHI within our company and with third parties. The
privacy, security and breach
56
notification rules promulgated under HIPAA, as amended by the HITECH Act, Standards for Privacy of Individually Identifiable Health
Information (Privacy Standards) and the Security Standards for the Protection of Electronic Protected Health Information (Security
Standards) under HIPAA establish a set of basic national privacy and security standards for the protection of individually identifiable health
information by Covered Entities and their Business Associates. HIPAA requires Covered Entities, such as us, to develop and maintain
policies and procedures with respect to individually identifiable health information that is used or disclosed, including the adoption of
administrative, physical and technical safeguards to protect the privacy and security of such information. HIPAA also requires us to provide
individuals with certain rights with respect to their PHI. If we engage a Business Associate to help us carry out healthcare activities and
functions, we must have a written Business Associate contract or other arrangement with the Business Associate that establishes specifically
what the Business Associate has been engaged to do and requires the Business Associate to comply with the requirements of HIPAA.
Further, in the event of a breach of unsecured PHI we must notify each individual whose PHI is breached as well as federal regulators and in
some cases, must publicize the breach in local or national media.
HIPAA also includes standards for common healthcare electronic transactions and code sets, such as claims information, plan eligibility,
payment information and the use of electronic signatures, and privacy and electronic security of individually identifiable health information.
Covered Entities, such as certain healthcare providers, are required to conform to such transaction set standards, known as the Standards
for Electronic Transactions, pursuant to HIPAA. Submission of electronic healthcare claims and payment transactions that do not comply with
the HIPAA electronic data transmission standards could result in delayed or denied payments.
In the conduct of our business, we process, maintain, and transmit sensitive data, including PHI. There can be no assurance that a breach of
privacy or security will not occur. If there is a breach, we could be subject to various lawsuits, penalties and damages and may be required to
incur costs to mitigate the impact of the breach on affected individuals.
Penalties for failure to comply with HIPAA requirements are substantial and could include corrective action plans and/or the imposition of civil
or criminal penalties. HIPAA also authorizes state attorneys general to file suit under HIPAA on behalf of state residents. Courts can award
damages, costs and attorneys’ fees related to violations of HIPAA in such cases. While HIPAA does not create a private right of action
allowing individuals to sue us in civil court for HIPAA violations, its standards have been used as the basis for a duty of care claim in state
civil suits such as those for negligence or recklessness in the misuse or breach of PHI.
Additionally, certain states have adopted comparable privacy and security laws and regulations, some of which may apply more broadly or be
more stringent than HIPAA. For example, the CCPA, which went into effect on January 1, 2020, gives California residents expanded rights to
access and delete their personal information, opt out of certain personal information sharing, and receive detailed information about how their
personal information is used. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is
expected to increase data breach litigation. Further, the CPRA went into effect in California amending the CCPA and may increase our
compliance costs and potential liability, imposes additional data protection obligations on covered businesses, including additional consumer
rights processes, limitations on data uses, new audit requirements for higher risk data and adds opt outs for certain uses of sensitive data. It
also created a new regulatory authority, the California Privacy Protection Agency (CPPA), which is authorized to issue substantive
regulations and could result in increased privacy and information security enforcement. In the event that we are subject to or affected by
HIPAA, the CCPA, the CPRA or other domestic privacy and data protection laws (for example Virginia's Consumer Data Protection Act and
other similar laws that recently went into effect in in other states, such as Utah, Colorado, Connecticut, Delaware, Florida, Indiana, Iowa,
Montana, Oregon, Tennessee, and Texas), any liability from failure to comply with the requirements of these laws could adversely affect our
financial condition.
In Europe, the GDPR went into effect in May 2018 and imposes strict requirements for processing the personal data of individuals within the
EEA. Companies that must comply with the GDPR face increased compliance obligations and risk, including more robust regulatory
enforcement of data protection requirements and potential fines for noncompliance of up to €20 million or 4% of the annual global revenues
of the noncompliant company, whichever is greater. Among other requirements, the GDPR regulates transfers of personal data subject to the
GDPR to third countries that have not been found to provide adequate protection to such personal data, including the United States, and the
efficacy and longevity of current transfer mechanisms between the EU and the United States remains uncertain. For example, in 2016, the
EU and United States agreed to a transfer framework for data transferred from the EU to the United States, called the Privacy Shield, but the
Privacy Shield was invalidated in July 2020 by the Court of Justice of the EU. In July 2023, however, the European Commission adopted an
adequacy decision for a new mechanism for transferring data from the EU to the United States – the EU-US Data Privacy Framework, which
provides EU individuals with several new rights, including the right to obtain access to their data, or obtain correction or deletion of incorrect
or unlawfully handled data. The adequacy decision followed
57
the signing of an executive order introducing new binding safeguards addressing the reasons behind the Court of Justice of the EU’s
invalidation of the original Privacy Shield. The European Commission will continually review developments in the United States along with its
adequacy decision. However, future actions of EU data protection authorities are difficult to predict.
Relatedly, following the United Kingdom’s withdrawal from the EU, the GDPR was implemented in the United Kingdom as the U.K. GDPR.
The U.K. GDPR sits alongside the amended U.K. Data Protection Act 2018, which implements certain derogations in the EU GDPR into U.K.
law. The U.K. GDPR mirrors the fines under the GDPR, i.e., fines up to the greater of €20 million (£17.5 million) or 4% of global turnover. In
June of 2021, the European Commission issued a decision, which will sunset on June 27, 2025 without further action, that the United
Kingdom ensures an adequate level of protection for personal data transferred under the EU GDPR from the EU to the United Kingdom. The
Parliament of the United Kingdom is currently considering the Data Protection and Digital Information Bill to harmonize the 2018 Data
Protection Act, U.K. GDPR, and the Privacy and Electronic Communications Regulations under one legislative framework.
The regulatory framework governing the collection, storage, use and sharing of certain information, particularly financial and other personal
information, is rapidly evolving and is likely to continue to be subject to uncertainty and varying interpretations. Additionally, increasing
concerns about health information privacy have recently prompted the federal government to issue guidance taking a newly expansive view
of the scope of the laws and regulations that they enforce. It is possible that these laws may be interpreted and applied in a manner that is
inconsistent with our existing practices. Any failure or perceived failure by us, or any third parties with which we do business, to comply with
our privacy policies, changing expectations, evolving laws, rules and regulations, industry standards or contractual obligations to which we or
such third parties are or may become subject, may result in actions or other claims against us by governmental entities or private actors, the
expenditure of substantial costs, time and other resources or the incurrence of significant fines, penalties or other liabilities. In addition, any
such action, particularly to the extent we were found to be guilty of violations or otherwise liable for damages, would damage our reputation
and adversely affect our business, financial condition and results of operations.
Although we work to comply with applicable laws, regulations and standards, our contractual obligations and other legal obligations, these
requirements are evolving and may be modified, interpreted and applied in an inconsistent manner from one jurisdiction to another and may
conflict with one another or other legal obligations with which we must comply. Any failure or perceived failure by us or our employees,
representatives, contractors, consultants, collaborators, or other third parties to comply with such requirements or adequately address
privacy and security concerns, even if unfounded, could result in additional cost and liability to us, damage our reputation and adversely
affect our business and results of operations.
Our future growth may depend, in part, on our ability to operate in foreign markets, where we would be subject to additional
regulatory burdens and other risks and uncertainties.
Our future growth may depend, in part, on our ability to develop and commercialize our testing products in foreign markets. We are not
permitted to market or promote any of our testing products before we receive regulatory approval from applicable regulatory authorities in
foreign markets, and we may never receive such regulatory approvals for any of our testing products. To obtain separate regulatory approval
in many other countries, we and our collaborators and service providers must comply with numerous and varying regulatory requirements
regarding safety and efficacy and governing, among other things, clinical trials, commercial sales, pricing and distribution of our testing
products. If we obtain regulatory approval of our testing products and ultimately commercialize our testing products in foreign markets, we
would be subject to additional risks and uncertainties, including any or all of the following:
•
•
•
•
•
•
•
different regulatory requirements for approval of IVDs in foreign countries;
reduced protection for intellectual property rights;
the existence of additional third-party patent rights of potential relevance to our business;
unexpected changes in tariffs, trade barriers and regulatory requirements;
economic weakness, including inflation, or political instability in particular foreign economies and markets;
compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;
foreign currency fluctuations, which could result in increased operating expenses and reduced revenue and other obligations incident
to doing business in another country;
58
•
•
inflationary pressures, such as those the global market is currently experiencing, which have and may increase costs for materials,
supplies, and services;
foreign reimbursement, pricing and insurance regimes;
• workforce uncertainty in countries where labor unrest is common;
•
•
production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and
business interruptions resulting from geopolitical actions, including war and terrorism, such as current conflicts in Ukraine and the
Middle East; natural disasters which may be exacerbated due to climate change, including earthquakes, typhoons, floods and fires;
outbreak of disease; boycotts; or other business restrictions.
Risks Related to our Intellectual Property
If we are unable to maintain intellectual property protection, our competitive position could be harmed.
Our ability to protect our technologies, such as the AVISE Lupus test, affects our ability to compete and to achieve sustained profitability. We
rely on a combination of U.S. and foreign patents and patent applications, copyrights, trademarks and trademark applications, and
contractual restrictions to protect our intellectual property rights. We cannot be certain that the claims in our granted patents and pending
patent applications covering our AVISE testing products will be considered patentable or enforceable by the United States Patent and
Trademark Office (the USPTO) courts in the United States, or by patent offices and courts in foreign countries. If we fail to protect our
intellectual property, third parties may be able to compete more effectively against us and we may incur substantial litigation costs in our
attempts to recover or restrict use of our intellectual property.
®
®
We apply for patents covering our testing products and technologies and uses thereof, as we deem appropriate, however we may fail to
apply for patents on important testing products and technologies in a timely fashion or at all, or we may fail to apply for patents in potentially
relevant jurisdictions, or we may cease our prosecution and maintenance of patents in potentially relevant jurisdictions. Currently, we have an
exclusive license to 12 issued U.S. patents, one Patent Cooperation Treaty application, and certain corresponding foreign counterpart
patents, relevant to our AVISE testing products. We own five issued U.S. patents, six pending U.S. patent applications, one pending U.S.
provisional patent application and certain corresponding foreign counterpart patents relevant to our AVISE testing products. While we intend
to pursue additional patent applications, it is possible that our pending patent applications and any future applications may not result in
issued patents. Even if such patents do successfully issue, third parties may challenge the validity, enforceability or scope thereof, which may
result in such patents being narrowed, invalidated or held unenforceable. Any successful opposition to our patents could deprive us of
®
exclusive rights necessary for the further development of our AVISE testing products. Furthermore, even if they are unchallenged, our
patents may not adequately protect our intellectual property, provide exclusivity for our AVISE testing products or prevent others from
designing around our claims.
®
®
®
We might not have been the first to make the inventions covered by each of our pending patent applications and we might not have been the
first to file patent applications for these inventions. To determine the priority of these inventions, we may have to participate in interference
proceedings, derivation proceedings or other post-grant proceedings declared by the USPTO that could result in substantial cost to us. No
assurance can be given that our patent applications will have priority over other patent applications. In addition, recent changes to the patent
laws of the United States allow for various post-grant opposition proceedings that have not been extensively tested, and their outcome is
therefore uncertain. Furthermore, if third parties bring these proceedings against our patents, we could experience significant costs and
management distraction.
We previously held licenses to five patent families related to CB-CAPs technology from the University of Pittsburgh (UPitt). We have
terminated these license agreements (related to U.S. Patent Nos. 7,361,517, 7,390,631, 7,585,640, 7,588,905, 8,080,382, 8,126,654, and
foreign equivalents thereof), effective March 22, 2024, and as a result may face increased competition with respect to the portion of our
testing products previously protected by these patents.
In addition to the protection afforded by patents, we rely on trade secret protection and confidentiality agreements to protect proprietary
know-how that is not patentable, or that we elect not to patent, processes for which patents are difficult to enforce and any other elements of
our AVISE testing products and development processes that involve proprietary know-how, information or technology that is not covered by
patents. However, trade secrets can be difficult to protect. While we use commercially reasonable efforts to protect our trade secrets, our
licensors,
®
59
employees, consultants, contractors and other advisors may unintentionally or willfully disclose such trade secret information to third parties
and competitors. We attempt to protect our proprietary technology in large part by entering into confidentiality and non-disclosure agreements
with our employees, consultants and other contractors. We cannot assure you, however, that these agreements will not be breached, that we
will have adequate remedies for any breach or that competitors will not know of, or independently discover, our trade secrets. We cannot
assure you that others will not independently develop substantially equivalent proprietary information or be issued patents that may prevent
the sale of our testing products, technologies, services or know-how or require licensing and the payment of significant fees or royalties by us
in order to produce our testing products, technologies or services. Further, we cannot be certain that the steps we have taken will prevent the
misappropriation of our trade secrets and other confidential information.
Monitoring unauthorized disclosure is difficult, and we do not know whether the steps we have taken to prevent such disclosure are, or will
be, adequate. If we were to enforce a claim that a third party had illegally obtained and was using our trade secrets, it would be expensive
and time consuming, and the outcome would be unpredictable. In addition, courts outside the United States may be less willing to protect
trade secrets. If we are unable to prevent unauthorized material disclosure of our trade secrets and other confidential information to third
parties, and in particular in jurisdictions where we have not filed for patent protection, we may not be able to establish or maintain a
competitive advantage in our market, which could materially adversely affect our business, operating results and financial condition.
Certain of our testing products utilize unpatented technology that is publicly available and can be used by our competitors.
®
Certain of our AVISE testing products, such as AVISE CTD, utilize both patented technology and publicly available technology that is not
protected by patents or other intellectual property rights. We believe that using certain publicly available technology allows us to offer a better
and more comprehensive testing product. However, the publicly available technology which we rely upon is also used in, and may continue to
be used in, products which compete with our AVISE testing products. Our competitors may independently develop competing diagnostic
products and services that do not infringe our intellectual property.
®
®
®
Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our AVISE
testing products.
Our success is heavily dependent on intellectual property, particularly on obtaining and enforcing patents. Obtaining and enforcing patents in
the diagnostics industry involves both technological and legal complexity, and is therefore costly, time-consuming and inherently uncertain.
The United States has enacted and is currently implementing wide-ranging patent reform legislation. Recent Supreme Court rulings have
narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. In
addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty
with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts and the USPTO, the
laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce
our existing patents and patents that we might obtain in the future. We cannot predict the breadth of claims that may be allowed or enforced
in our patents or in third-party patents. We may not develop additional proprietary products, methods and technologies that are patentable.
Some of our intellectual property has been discovered through government funded programs and thus may be subject to federal
regulations such as “march-in” rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with
such regulations may limit our exclusive rights, and limit our ability to contract with non-U.S. manufacturers.
Some of the intellectual property rights we have acquired or licensed or may acquire or license in the future may have been generated
through the use of U.S. government funding and may therefore be subject to certain federal regulations. For example, some of the research
and development work related to our CB-CAPs technology was funded by government research grants. As a result, the U.S. government
may have certain rights to intellectual property embodied in our testing products pursuant to the Bayh-Dole Act of 1980 (Bayh-Dole Act).
These U.S. government rights include a non-exclusive, non-transferable, irrevocable worldwide license to use inventions for any
governmental purpose. In addition, the U.S. government has the right, under certain limited circumstances, to require us to grant exclusive,
partially exclusive or non-exclusive licenses to any of these inventions to a third party if it determines that: (i) adequate steps have not been
taken to commercialize the invention; (ii) government action is necessary to meet public health or safety needs; or (iii) government action is
necessary to meet requirements for public use under federal regulations (also referred to as “march-in rights”). The U.S. government also
has the right to take title to these inventions if the grant recipient fails to disclose the invention to the government or fails to file an
60
application to register the intellectual property within specified time limits. Intellectual property generated under a government funded
program is also subject to certain reporting requirements, compliance with which may require us to expend substantial resources. In addition,
the U.S. government requires that any products embodying any of these inventions or produced through the use of any of these inventions
be manufactured substantially in the United States. This preference for U.S. industry may be waived by the federal agency that provided the
funding if the owner or assignee of the intellectual property can show that reasonable but unsuccessful efforts have been made to grant
licenses on similar terms to potential licensees that would be likely to manufacture substantially in the United States or that under the
circumstances domestic manufacture is not commercially feasible. This preference for U.S. industry may limit our ability to contract with non-
U.S. product manufacturers for products covered by such intellectual property. To the extent any of our future intellectual property is also
generated through the use of U.S. government funding, the provisions of the Bayh-Dole Act may similarly apply.
We may not be able to protect our intellectual property rights throughout the world.
®
Filing, prosecuting and defending patents on our AVISE testing products in all countries throughout the world would be prohibitively
expensive. Moreover, we believe that obtaining foreign patents may be more difficult than obtaining domestic patents because of differences
in patent laws and, accordingly, our patent position may be stronger in the United States than abroad. In addition, the laws of some foreign
countries do not protect intellectual property rights in the same manner and to the same extent as laws in the United States. Various
countries limit the subject matter that can be patented and limit the ability of a patent owner to enforce patents in the medical and other
related fields. This may limit our ability to obtain or utilize those patents internationally. In order to manage our foreign patent costs and focus
on the U.S. market, we made the decision to cease the prosecution and maintenance of certain of our foreign patents and patent applications
related to our CB-CAPs technology, which is used in our AVISE testing products. Consequently, we may not be able to prevent third parties
from practicing our inventions in all countries outside the United States. Competitors may use our technologies in jurisdictions where we have
not obtained patent protection to develop their own products and further, may export otherwise infringing products to territories where we
have patent protection, but enforcement of such patent protection is not as strong as that in the United States. These products may compete
with our AVISE testing products and our patents or other intellectual property rights may not be effective or sufficient to prevent them from
competing.
®
®
Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The
legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other
intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the
infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our
patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business,
could put our patents at risk of being invalidated or interpreted narrowly, and could provoke third parties to assert claims against us. We may
not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful.
Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial
advantage from the intellectual property that we develop or license.
The patent protection and patent prosecution for some of our testing products may be dependent on third parties.
We or our licensors may fail to identify patentable aspects of inventions made in the course of development and commercialization activities
before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position. It is
possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example
with respect to proper priority claims, inventorship, claim scope or requests for patent term adjustments. If we or our licensors, whether
current or future, fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or
eliminated. If our licensors are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent
rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution or enforcement of our
patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid,
enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse
impact on our business.
As a licensee of third parties, we rely on third parties to file and prosecute patent applications and maintain patents and otherwise protect the
licensed intellectual property under some of our license agreements. We have not had and do not have primary control over these activities
for certain of our patents or patent applications and other intellectual property rights. We cannot be certain that such activities by third parties
have been or will be conducted
61
in compliance with applicable laws and regulations or will result in valid and enforceable patents or other intellectual property rights. Pursuant
to the terms of the license agreements with some of our licensors, the licensors may have the right to control enforcement of our licensed
patents or defense of any claims asserting the invalidity of these patents and even if we are permitted to pursue such enforcement or
defense, we will require the cooperation of our licensors. We cannot be certain that our licensors will allocate sufficient resources or prioritize
their or our enforcement of such patents or defense of such claims to protect our interests in the licensed patents. Even if we are not a party
to these legal actions, an adverse outcome could harm our business because it may permit other parties to compete with us. If any of our
licensors or any of our future licensors or future collaborators fail to appropriately prosecute and maintain patent protection for patents
covering any of our testing products, our ability to develop and commercialize those testing products may be adversely affected and we may
not be able to prevent competitors from making, using and selling competing products.
In addition, even where we have the right to control patent prosecution of patents and patent applications we have acquired or licensed from
third parties, we may still be adversely affected or prejudiced by actions or inactions of our predecessors or licensors and their counsel that
took place prior to us assuming control over patent prosecution.
Our technology acquired or licensed from various third parties may be subject to retained rights. Our predecessors or licensors often retain
certain rights under their agreements with us, including the right to use the underlying technology for noncommercial academic and research
use, to publish general scientific findings from research related to the technology and to make customary scientific and scholarly disclosures
of information relating to the technology. It is difficult to monitor whether our predecessors or licensors limit their use of the technology to
these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.
If we are limited in our ability to utilize acquired or licensed technologies, or if we lose our rights to critical in-licensed technology, we may be
unable to successfully develop, out-license, market and sell our testing products, which could adversely affect our business. Our business
strategy depends on the successful development of licensed and acquired technologies into commercial products. Therefore, any limitations
on our ability to utilize these technologies may impair our ability to develop, out-license or market and sell our testing products.
If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties or
otherwise experience disruptions to our business relationships with our licensors, we could lose license rights that are important
to our business.
We are a party to a number of license agreements under which we are granted intellectual property rights that are important to our business.
For example, we license certain patent rights from AHN, QMUL and JHU. Our existing license agreements impose various regulatory and/or
commercial diligence obligations, payment of milestones and/or royalties and other obligations. If we fail to comply with our obligations under
a license agreement, the license agreement may be terminated, in which event we would not be able to further develop or market certain
AVISE testing products. Additionally, we may not always have the first right to maintain, enforce or defend our licensed intellectual property
rights and, although we would likely have the right to assume the maintenance, enforcement and defense of such intellectual property rights
if our licensors do not, our ability to do so may be compromised by our licensors’ acts or omissions.
®
Licensing of intellectual property rights is of critical importance to our business and involves complex legal, business and scientific issues.
Disputes may arise between us and our licensors regarding intellectual property rights subject to a license agreement, including the scope of
rights granted under the license agreement and other interpretation-related issues, and whether and the extent to which our technology and
processes infringe on intellectual property rights of the licensor that are not subject to the licensing agreement. If disputes over intellectual
property rights that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, our
business, results of operations, financial condition and prospects may be adversely affected. We may enter into additional licenses in the
future and if we fail to comply with obligations under those agreements, we could suffer adverse consequences.
Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee
payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or
eliminated for non-compliance with these requirements.
The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment
and other similar provisions during the patent process. Periodic maintenance fees, renewal fees, annuity fees and various other
governmental fees on any issued patents and/or applications are due to be paid to the USPTO and foreign patent agencies in several stages
over the lifetime of the patents and/or applications. Our outside counsel has systems in place to monitor deadlines to pay these fees and to
remind us of
62
these fees, and our outside counsel employs an outside firm to pay these fees due to the USPTO and to foreign patent agencies based on
our instructions. In the aggregate, these fees can be cost prohibitive for an early-stage company. Accordingly, we made a financially-driven
decision to prioritize our payment of these fees and to allow certain of our applications to lapse, particularly with respect to our ex-U.S. rights
licensed from UPitt related to our CB-CAPs technology. The permanent lapse of certain of these ex-U.S. rights may result in our patent
position being stronger in the United States than abroad, such as in countries that are part of the European Patent Convention, and third
parties may be able to compete more effectively against us in countries outside the United States, including in those countries that belong to
the European Patent Convention. Additionally, while an inadvertent lapse may sometimes be cured by payment of a late fee or by other
means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent
or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, our competitors might
be able to enter the market earlier than should otherwise have been the case, which would have a material adverse effect on our business.
We may not be successful in obtaining or maintaining necessary rights to product components and processes for our
development pipeline through acquisitions and in-licenses.
®
Presently we have intellectual property rights, through licenses from third parties and under patents that we own, related to our AVISE
testing products. Because our programs may involve additional products that require the use of proprietary rights held by third parties, the
growth of our business will likely depend in part on our ability to acquire, in-license or use these proprietary rights. We may be unable to
acquire or in-license proprietary rights that we identify as being necessary for our AVISE testing products. Even if we are able to obtain a
license to such proprietary rights, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In
that event, we may be required to expend significant time and resources to develop or license replacement technology.
®
The licensing and acquisition of third-party proprietary rights is a competitive area, and companies, which may be more established, or have
greater resources than we do, may also be pursuing strategies to license or acquire third-party proprietary rights that we may consider
necessary or attractive in order to further develop our AVISE testing products. More established companies may have a competitive
advantage over us due to their size, cash resources and greater clinical development and commercialization capabilities.
®
In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us, either on reasonable terms, or at
all. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate
return on our investment, or at all. If we are unable to successfully obtain rights to required third-party intellectual property rights on
commercially reasonable terms, our ability to further develop our AVISE testing products and our business, financial condition and prospects
for growth could suffer.
®
Third-party claims alleging intellectual property infringement may prevent or delay our development efforts.
Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties. There is a
substantial amount of litigation, both within and outside the United States, involving patents and other intellectual property rights in the
diagnostics industry, as well as administrative proceedings for challenging patents, including interference and reexamination proceedings
before the USPTO or oppositions and other comparable proceedings in foreign jurisdictions. The Leahy-Smith America Invents Act
introduced new procedures including inter partes review and post grant review. The implementation of these procedures brings the possibility
of third-party challenges to our patents and the outcome of such challenges could result in a loss or narrowing of our patent rights. In such an
event, our competitors might be able to enter the market earlier than should otherwise have been the case, which would have a material
adverse effect on our business. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third
parties, exist in the fields in which we are developing our AVISE testing products. As the diagnostics industry expands and more patents are
issued, the risk increases that our activities related to our AVISE testing products may give rise to claims of infringement of the patent rights
of others.
®
®
We cannot assure you that any of our current or future AVISE testing products will not infringe existing or future patents. Although we are
not aware of any issued patents that will prevent us from marketing our AVISE testing products, there may be third-party patents of which
we are currently unaware with claims to materials or methods of manufacture related to the use or manufacture of our AVISE testing
products. If a third party that owns such a patent asserts it successfully against one of our current or future AVISE testing products, we may
be unable to market our product, which could materially harm our business and because patent applications can take many years to issue
and may be confidential for 18 months or more after filing, there may be currently pending third-party
®
®
®
®
63
patent applications which may later result in issued patents that our AVISE testing products or our technologies may infringe, or which such
third parties claim are infringed by the use of our technologies.
®
Parties making claims against us for infringement or misappropriation of their intellectual property rights may seek and obtain injunctive or
other equitable relief, which could effectively block our ability to further develop one or more of our AVISE testing products. Defense of these
claims, regardless of their merit, would involve substantial expenses and would be a substantial diversion of employee resources from our
business. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages
and attorneys’ fees if we are found to be willfully infringing a third party’s patents, obtain one or more licenses from third parties, pay royalties
or redesign our infringing products, which may be impossible or require substantial time and monetary expenditure. We cannot predict
whether any such license would be available at all or whether it would be available on commercially reasonable terms. Furthermore, even in
the absence of litigation, we may need to obtain licenses from third parties to advance our research or development of our AVISE testing
products. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we would be unable
to further develop our AVISE testing products, which could harm our business significantly. Even if we were able to obtain a license, the
rights may be nonexclusive, which may give our competitors access to the same intellectual property.
®
®
®
In addition to infringement claims against us, if third parties have prepared and filed patent applications in the United States that also claim
technology to which we have rights, we may have to participate in interference proceedings in the USPTO to determine the priority of
invention. Third parties may also attempt to initiate reexamination, post grant review or inter partes review of our patents in the USPTO. We
may also become involved in similar proceedings in the patent offices in other jurisdictions regarding our intellectual property rights with
respect to our AVISE testing products and technology.
®
We may be involved in proceedings to protect or enforce our patents or the patents of our licensors, which could be expensive,
time-consuming and unsuccessful.
Third parties may infringe, misappropriate or otherwise violate our existing patents, patents that may be issued to us in the future, or the
patents of our licensors that are licensed to us. To counter infringement or unauthorized use, we may be required to file infringement claims,
which can be expensive and time-consuming. We may not be able to prevent, alone or with our licensors, misappropriation of our intellectual
property rights, particularly in countries where the laws may not protect those rights as fully as in the United States.
®
In addition, if we or one of our licensors initiated legal proceedings against a third party to enforce a patent covering one of our AVISE
testing products, the defendant could counterclaim that the patent covering such AVISE testing product is invalid and/or unenforceable. In
patent litigation in the United States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace, and there are
numerous grounds upon which a third party can assert invalidity or unenforceability of a patent. Such proceedings could result in an
invalidation of our patents. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the
validity question, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware
during prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and
perhaps all, of the patent protection on our AVISE testing products. Such a loss of patent protection could have a material adverse impact
on our business.
®
®
Litigation proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees.
Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that
some of our confidential information could be compromised by disclosure during this type of litigation. In addition, there could be public
announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive
these results to be negative, it could have a substantial adverse effect on the price of our common stock.
Because of the expense and uncertainty of litigation, we may not be in a position to enforce our intellectual property rights against
third parties.
Because of the expense and uncertainty of litigation, we may conclude that even if a third party is infringing our patents or other intellectual
property rights, the risk-adjusted cost of bringing and enforcing such a claim or action may be too high or not in the best interest of our
company or our stockholders. We are not aware of any third-party infringement of our intellectual property rights that would have a materially
adverse impact on our business. In addition, there can be no assurance that our licensors will be willing to bring and enforce claims to
prevent third parties from infringing intellectual property that is licensed to us, particularly if the affected intellectual property is less important
to the licensor’s business than to ours. In such cases, we may decide that the more prudent course of action is to simply monitor the situation
or initiate or seek some other non-litigious action or solution.
64
We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed
confidential information of third parties.
We have received confidential and proprietary information from third parties. In addition, we employ individuals who were previously
employed at other companies in our industry. We may be subject to claims that we or our employees, consultants or independent contractors
have inadvertently or otherwise improperly used or disclosed confidential information of these third parties or our employees’ former
employers. Further, we may be subject to ownership disputes in the future arising, for example, from conflicting obligations of consultants or
others who are involved in developing our AVISE testing products. We may also be subject to claims that former employees, collaborators
or other third parties have an ownership interest in our patents or other intellectual property. Litigation may be necessary to defend against
these and other claims challenging our right to and use of confidential and proprietary information. If we fail in defending any such claims, in
addition to paying monetary damages, we may lose our rights therein. Such an outcome could have a material adverse effect on our
business. Even if we are successful in defending against these claims, litigation could result in substantial cost and be a distraction to our
management and employees.

Risks Related to Our Common Stock
Our stock price may be volatile, and you may not be able to sell shares of our common stock at or above the price you paid.
The public trading price for our common stock is affected by a number of factors, including:
•
•
•
•
•
•
•
•
•
•
•
•
•
actual or anticipated variations in our and our competitors’ financial condition and results of operations;
announcements by us or our competitors of new products, strategic partnerships or capital commitments;
changes in reimbursement by current or potential third-party payors;
issuance of new securities analysts’ reports or changed recommendations for our stock;
actual or anticipated changes in regulatory oversight of our testing products;
developments or disputes concerning our intellectual property or other proprietary rights;
commencement of, or our involvement in, litigation;
announced or completed acquisitions of businesses or technologies by us or our competitors;
any major change in our management;
changes in accounting principles;
announcement or expectation of additional financing efforts;
future sales of our common stock by our executive officers, directors and other stockholders; and
general economic conditions and slow or negative growth of our markets, including as a result of the current conflict in the Ukraine
and the Middle East.
In addition, the stock market in general, and the market for stock of life sciences companies in particular, has experienced extreme price and
volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and
industry factors, as well as general economic, political and market conditions such as recessions or interest rate changes, may seriously
affect the market price of our common stock, regardless of our actual operating performance. As a result of this volatility, you may not realize
any return on your investment in us and may lose some or all of your investment.
In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities
class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial
costs and a diversion of our management’s attention and resources. Any adverse determination in any such litigation or any amounts paid to
settle any such actual or threatened litigation could require that we make significant payments.
Future sales of shares by existing stockholders could cause our stock price to decline.
65
Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur could
significantly reduce the trading price of our common stock and impair our ability to raise adequate capital through the sale of additional equity
securities.
In addition, our directors and executive officers have and may continue to establish programmed selling plans under Rule 10b5-1 of the
Exchange Act for the purpose of effecting sales of our common stock. Any sales of securities by directors and executive officers, or the
perception that those sales may occur, including the entry into such programmed selling plans, could have a material adverse effect on the
trading price of our common stock, particularly if the trading volume of our common stock is relatively low at the time of these sales.
Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider
favorable and may lead to entrenchment of management.
Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could significantly reduce
the value of our shares to a potential acquiror or delay or prevent changes in control or changes in our management without the consent of
our board of directors. The provisions in our charter documents include the following:
•
•
•
•
•
•
•
•
•
•
•
a classified board of directors with three-year staggered terms, which may delay the ability of stockholders to change the
membership of a majority of our board of directors;
no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;
the exclusive right of our board of directors, unless the board of directors grants such right to the stockholders, to elect a director to
fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a director, which prevents
stockholders from being able to fill vacancies on our board of directors;
the required approval of at least 66-2/3% of the shares entitled to vote to remove a director for cause, and the prohibition on removal
of directors without cause;
the ability of our board of directors to authorize the issuance of shares of preferred stock and to determine the price and other terms
of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the
ownership of a hostile acquiror;
the ability of our board of directors to alter our amended and restated bylaws without obtaining stockholder approval;
the required approval of at least 66-2/3% of the shares entitled to vote to adopt, amend or repeal our amended and restated bylaws
or repeal the provisions of our amended and restated certificate of incorporation regarding the election and removal of directors;
a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of
our stockholders;
an exclusive forum provision providing that the Court of Chancery of the State of Delaware will be the exclusive forum for certain
actions and proceedings;
the requirement that a special meeting of stockholders may be called only by the board of directors, which may delay the ability of
our stockholders to force consideration of a proposal or to take action, including the removal of directors; and
advance notice procedures that stockholders must comply with in order to nominate candidates to our board of directors or to
propose matters to be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquiror from conducting a
solicitation of proxies to elect the acquiror’s own slate of directors or otherwise attempting to obtain control of us.
We are also subject to the anti-takeover provisions contained in Section 203 of the Delaware General Corporation Law. Under Section 203, a
corporation may not, in general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has
held the stock for three years or, among other exceptions, the board of directors has approved the transaction.
Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the
exclusive forum for substantially all disputes between us and our stockholders, which
66
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 provide 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, our amended and restated certificate of incorporation, or any action
asserting a claim against us that is governed by the internal affairs doctrine; provided, that, this provision would not apply to suits brought to
enforce a duty or liability created by the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive
jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive
federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder.
Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any
duty or liability created by the Securities Act or the rules and regulations thereunder. These choice of forum provisions may limit a
stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees,
which may discourage such lawsuits against us and our directors, officers and other employees. By agreeing to this provision, however, the
stockholders will not be deemed to have waived our compliance with the Federal Securities laws and rules and regulations thereunder.
Furthermore, the enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in
legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. If a court were to
find the choice of forum provisions in our amended and restated 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 adversely affect our business and
financial condition.
Our executive officers, directors and principal stockholders, if they choose to act together, have the ability to control or
significantly influence all matters submitted to stockholders for approval.
Based on their most recent publicly filed beneficial ownership reports, our greater than 5% stockholders collectively own approximately 64%
of our outstanding capital stock and our greater than 5% stockholders, directors and executive officers collectively own (without duplication)
approximately 65% of our outstanding capital stock as of February 15, 2024. As a result, such persons, acting together, have the ability to
control or significantly influence all matters submitted to our stockholders for approval, including the election and removal of directors and
approval of any significant transaction, as well as our management and business affairs. This concentration of ownership may have the effect
of delaying, deferring or preventing a change in control, impeding a merger, consolidation, takeover or other business combination involving
us, or discouraging a potential acquiror from making a tender offer or otherwise attempting to obtain control of our business, even if such a
transaction would benefit other stockholders.
We have never paid dividends on our capital stock, and we do not anticipate paying dividends in the foreseeable future. Your
ability to achieve a return on your investment will depend on appreciation, if any, in the price of our common stock.
We have never declared or paid any cash dividends on our common stock and do not intend to pay any cash dividends in the foreseeable
future. We currently intend to retain any future earnings to fund the growth of our business. In addition, our Amended Loan Agreement
restricts our ability to pay cash dividends on our common stock and we may also enter into credit agreements or other borrowing
arrangements in the future that will restrict our ability to declare or pay cash dividends on our common stock. Any determination to pay
dividends in the future will be at the discretion of our board of directors and will depend on our financial condition, operating results, capital
requirements, general business conditions and other factors that our board of directors may deem relevant. As a result, capital appreciation,
if any, of our common stock will be the sole source of gain for the foreseeable future.
An active, liquid trading market for our common stock may not be maintained.
Prior to our initial public offering (IPO), there had been no public market for our common stock. Our common stock began trading on The
Nasdaq Global Market (Nasdaq) relatively recently, but we can provide no assurance that we will be able to develop and sustain an active
trading market for our common stock. Even if an active trading market is developed, it may not be sustained. The lack of an active market
may impair your ability to sell your shares at the time you wish to sell them or at a price that you consider reasonable. An inactive market
may also impair our ability to raise capital by selling shares and may impair our ability to acquire other businesses or technologies using our
shares as consideration, which, in turn, could materially adversely affect our business. During 2023, our average daily trading volume has
been approximately 25,040 shares.
Our failure to meet the continued listing requirements of Nasdaq or The Nasdaq Stock Market LLC could result in a delisting of our
common stock.
67
If we fail to satisfy the continued listing requirements of Nasdaq, such as the corporate governance requirements or the minimum closing bid
price requirement, Nasdaq may take steps to delist our common stock. Such a delisting would likely have a negative effect on the price of our
common stock and would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a delisting, we can
provide no assurance that any action taken by us to restore compliance with listing requirements would allow our common stock to become
listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the
Nasdaq minimum bid price requirement or prevent future non-compliance with Nasdaq’s listing requirements.
If securities or industry analysts downgrade our common stock or otherwise issue adverse opinions or commentary regarding our
stock or do not publish research or reports about our company, our stock price and trading volume could decline.
The trading market for our common stock depends in part on the research and reports that equity research analysts publish about us and our
business. Currently, we have limited analyst coverage and we do not have any control over such analysts or the content and opinions
included in their reports. Securities analysts may elect not to provide research coverage of our company, and such lack of research coverage
may adversely affect the market price of our common stock. The price of our common stock could also decline if one or more equity research
analysts downgrade our common stock or if those analysts issue other unfavorable commentary or cease publishing reports about us or our
business. If one or more equity research analysts cease coverage of our company, we could lose visibility in the market, which in turn could
cause our stock price to decline.
We could be subject to securities class action litigation.
In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities.
This risk is especially relevant for us because life sciences and diagnostics companies have experienced significant stock price volatility in
recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which
could harm our business.
Not applicable.
Item 1B. Unresolved Staff Comments.
Item 1C. Cybersecurity.
We recognize the critical importance of maintaining the trust and confidence of physicians, patients, business partners and employees
toward our business and are committed to protecting the confidentiality, integrity and availability of our business operations and systems. Our
board of directors is actively involved in oversight of our risk management activities, and cybersecurity represents an important element of
our overall approach to risk management. Our cybersecurity policies, standards, processes and practices are based on recognized
frameworks established by NIST and other applicable industry standards, as well as the HIPAA Security Rule and other recognized
frameworks. In general, we seek to address cybersecurity risks through a comprehensive, cross-functional approach that is focused on
preserving the confidentiality, security and availability of the information that we collect and store by identifying, preventing and mitigating
cybersecurity threats and effectively responding to cybersecurity incidents when they occur.
Cybersecurity Risk Management and Strategy; Effect of Risk
We face risks related to cybersecurity such as unauthorized access, cybersecurity attacks and other security incidents, including as
perpetrated by hackers and unintentional damage or disruption to hardware and software systems, loss of data, and misappropriation of
confidential information. To identify and assess material risks from cybersecurity threats, we maintain a comprehensive cybersecurity
program to ensure our systems are effective and prepared for information security risks, including regular oversight of our programs for
security monitoring for internal and external threats to ensure the confidentiality and integrity of our information assets. We consider risks
from cybersecurity threats in addition to other company risks as part of our overall risk assessment process. We employ a range of tools and
services, including regular network and endpoint monitoring, audits, vulnerability assessments, and penetration testing to inform our risk
identification and assessment. As discussed in more detail under “Cybersecurity Governance” below, our Audit Committee provides oversight
of our cybersecurity risk management and strategy processes, which are led by our Vice President of Information Services.
We also identify our cybersecurity threat risks by comparing our processes to standards set by NIST, as well as performing intrusion
detection and prevention. To provide for the availability of critical data and systems, maintain
68
regulatory compliance, manage our material risks from cybersecurity threats, and protect against and respond to cybersecurity incidents, we
undertake the following activities:
a. monitor emerging data protection laws and implement changes to our processes that are designed to comply with such laws;
b.
through our policies, practices and contracts (as applicable), require employees, as well as third parties that provide services on our
behalf, to treat confidential information and data with care;
c. employ technical safeguards that are designed to protect our information systems from cybersecurity threats, including firewalls,
intrusion prevention and detection systems, anti-malware functionality and access controls, which are evaluated and improved
through vulnerability assessments and cybersecurity threat intelligence;
d. provide regular, mandatory training for our employees regarding cybersecurity threats as a means to equip them with effective tools
to address cybersecurity threats, and to communicate our evolving information security policies, standards, processes and practices;
e. conduct regular phishing email simulations for all employees with access to our email systems to enhance awareness and
responsiveness to possible threats;
f.
g.
conduct monthly cybersecurity management and incident training for employees involved in our systems and processes that handle
sensitive data;
leverage internal and external resources to help us identify, protect, detect, respond and recover when there is an actual or potential
cybersecurity incident; and
h. carry information security risk insurance that provides protection against the potential losses arising from a cybersecurity incident
Our incident response plan coordinates the activities we take to prepare for, detect, respond to and recover from cybersecurity incidents,
which include processes to triage, assess severity for, escalate, contain, investigate and remediate the incident, as well as to comply with
potentially applicable legal obligations and mitigate damage to our business and reputation. As part of the above processes, we rely on
internal resources rather than consultants, auditors or other third parties, to review our cybersecurity program.
Our processes also address cybersecurity threat risks associated with our use of third-party service providers, including our suppliers and
manufacturers or who have access to patient and employee data or our systems. In addition, cybersecurity considerations affect the
selection and oversight of our third-party service providers. We perform diligence on third parties that have access to our systems, data or
facilities that house such systems or data.
We describe whether and how risks from identified cybersecurity threats, including as a result of any previous cybersecurity incidents, have
materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition,
under the heading “Failure in our information technology, telephone or other systems could significantly disrupt our operations and adversely
affect our business and financial condition,” which disclosures are incorporated by reference herein.
Cybersecurity Governance; Management
Cybersecurity is an important part of our risk management processes and an area of focus for our board of directors and management. In
general, our board of directors oversees risk management activities designed and implemented by our management, and considers specific
risks, including, for example, risks associated with our strategic plan, business operations, and capital structure. Our board of directors
executes its oversight responsibility for risk management both directly and through delegating oversight of certain of these risks to its
committees, and our board of directors has authorized our Audit Committee to oversee risks from cybersecurity threats.
Upon detection of a material cybersecurity threat, our Audit Committee receives an update from management of the cybersecurity threat, risk
management and strategy processes, as well as the steps management has taken to respond to such risks. In such sessions, our Audit
Committee generally receives materials that include cybersecurity materials discussing current material cybersecurity threat risks, and
describing our ability to mitigate those risks, and discusses such matters with our Chief Executive Officer. Our Audit Committee and board of
directors receive prompt and timely information regarding any cybersecurity incident that meets established reporting thresholds.

Our cybersecurity risk management and strategy processes, which are discussed in greater detail above, are led by our Vice President of
Information Services, with support from our entire Information Services department. Such individuals have collectively over 10 years of prior
work experience in various roles involving managing information security, developing cybersecurity strategy, implementing effective
information and cybersecurity programs, as well as several relevant degrees and certifications. These Information Services team members
are informed about and monitor the prevention, mitigation, detection, and remediation of cybersecurity incidents through their management
of, and participation in, the cybersecurity risk management and strategy processes described above, including the operation of our incident
response plan. As discussed above, these Information Services team members report to our Chief Executive Officer, and ultimately to the
Audit Committee of our board of directors about material cybersecurity threats.

Item 2. Properties.
Our corporate headquarters are located in Vista, California, where we lease approximately 27,000 square feet of office and laboratory space
under a lease that expires in 2027, with an option to extend a portion of the lease for an additional five-year period.
We also lease approximately 28,000 square feet of additional office space in Carlsbad, California, under a sublease that is co-terminus with
our other lease expiring in 2027. We believe that our current facilities are adequate for our current needs and that suitable additional or
alternative spaces will be available in the future on commercially reasonable terms, if required.
Item 3. Legal Proceedings.
From time to time, we may be involved in legal proceedings or subject to claims incident to the ordinary course of business. Regardless of
the outcome, such proceedings or claims can have an adverse impact on us because of defense and settlement costs, diversion of
resources and other factors, and there can be no assurances that favorable outcomes will be obtained.
In October 2023, we resolved an investigation with the U.S. Attorney’s Office for the District of Massachusetts that was initiated by a qui tam
lawsuit. Pursuant to a Settlement Agreement, we made a single lump-sum remittance to the government in the amount of $0.7 million plus
interest in connection with specimen processing arrangements that we historically had with physicians. The U.S. Attorney’s Office dismissed
this “covered conduct” in the qui tam with prejudice, while non-covered conduct was dismissed without prejudice. In November 2023, the
complaint was unsealed and served on us. We filed a motion to dismiss the complaint. In February 2024, the relator filed a motion for leave
to amend the complaint. We opposed this motion, and all motions are still pending. The Company intends to vigorously defend against the
claims being asserted in the complaint.

You should read the following discussion of our financial condition and results of operations in conjunction with the financial statements and
the notes thereto included elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis
or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business and
financial performance, includes forward-looking statements that are based on current beliefs, plans and expectations and involve risks,
uncertainties and assumptions. You should read the "Special note regarding forward-looking statements" and "Risk Factors" section of this
Annual Report on Form 10-K for a discussion of important factors that could cause our actual results to differ materially from the results
described in or implied by the forward-looking statements contained in the following discussion and analysis.
Overview
We exist to provide clarity in autoimmune disease decision making with the goal of improving patients' clinical outcomes. We have developed
and are commercializing a portfolio of innovative testing products under our AVISE brand, which allow for the differential diagnosis,
prognosis and monitoring of complex autoimmune and autoimmune-related diseases. There is an unmet need for rheumatologists to add
clarity in their CTD clinical evaluation, and we believe there is a significant opportunity for our tests in this market, particularly for potentially
life-threatening diseases such as SLE.
®
®
Since inception we have devoted substantially all of our efforts to developing and marketing products for the diagnosis, prognosis and
®
monitoring of autoimmune diseases. We commercially launched our lead testing product, AVISE CTD, in 2012. Our proprietary AVISE
Lupus test is included as part of the AVISE CTD panel and employs a patent-protected method for diagnosing patients with SLE based on
levels of CB-CAPs (e.g. EC4d and BC4d), ANA, and ds-DNA. The AVISE Lupus test also employs patent-protected algorithms used to
generate risk scores to diagnose patients with SLE based on the levels of the biomarkers. These proprietary, patent-protected methods
vastly improve the diagnostic sensitivity of our test compared to the current standard of care. AVISE CTD enables differential diagnosis for
patients presenting with symptoms indicative of a wide variety of CTDs and other related diseases with overlapping symptoms. Revenue
from this product comprised 88% and 84% of our revenue for the years ended December 31, 2023 and 2022, respectively. For the years
ended December 31, 2023 and 2022, we incurred net losses of $23.7 million and $47.4 million, respectively, and we expect to continue to
incur operating losses in the near term. Our operations have been funded primarily through equity financings, debt financings and revenue
from product sales. We have never been profitable and, as of December 31, 2023, we had $36.5 million of cash and cash equivalents and an
accumulated deficit of $279.2 million.
®
®
®
Reimbursement for our testing services comes from several sources, including commercial payors (such as insurance companies and health
maintenance organizations), government payors (such as Medicare and Medicaid), and patients. Reimbursement rates vary by product and
payor.
®
All of our AVISE tests are performed in our approximately 13,000 square foot laboratory located in Vista, California, which is certified under
the CLIA and accredited by CAP. Our laboratory is certified for performance of high-complexity testing by CMS in accordance with CLIA and
is licensed by all states requiring out-of-state licensure. Our clinical laboratory typically reports all AVISE testing product results within five
business days.
®
®
We market our AVISE testing products using our specialized sales force covering 40 territories in the United States. Many diagnostic sales
forces are trained only to understand the comparative benefits of the tests they promote. In contrast, the specialized backgrounds of our
sales personnel, coupled with our comprehensive training, enables our sales representatives to interpret results from our de-identified patient
test reports and provide unique insights in a highly tailored discussion with rheumatologists. We believe our focus on and experience in the
field of rheumatology, combined with our commitment to excellent customer service and support, position us very well to respond to the
needs of rheumatologists and the patients they serve.
Factors Affecting Our Performance
We believe there are several important factors that have impacted, and that we expect will impact, our operating performance and results of
operations, including:
▪ Reimbursement for Our Testing Products. Our revenue depends on achieving broad coverage and reimbursement for our tests
from third-party payors, including both commercial payors and government payors. Payment from third-party payors differs
depending on whether we are considered a "participating provider" (have entered into a contract with the payors as a participating
provider) or a "non-participating provider" (do not have a contract and are considered a "non-participating provider"). Payors will
often
73
reimburse non-participating providers at a lower amount than participating providers, if at all. We have received a substantial portion
of our revenue from a limited number of commercial payors, most of which have not contracted with us to be a participating provider.
Historically, we have experienced situations where commercial payors proactively reduced the amounts they were willing to
reimburse for our tests, and in other situations, commercial payors have determined that the amounts they previously paid were too
high and have sought to recover those perceived excess payments by deducting such amounts from payments otherwise being
made. When we contract to serve as a participating provider, reimbursements are made pursuant to a negotiated fee schedule and
are limited to only covered indications. If we are not able to obtain or maintain coverage and adequate reimbursement from third-
party payors, we may not be able to effectively increase our testing volume and revenue as expected. Additionally, changes in our
estimated reimbursements for tests performed in prior periods can positively or negatively impact our revenue in the current period
and cause our financial results to fluctuate. In addition, in connection with our revenue cycle management initiatives, we plan to hold
claims in the first half of the year which will likely result in increases in our accounts receivable and an accelerated decrease in our
cash in the first half of the year which we would expect to return to typical levels by the end of our fiscal year.
▪ Continued Growth of Our Testing Products. Since the launch of AVISE CTD in 2012 and through December 31, 2023, we have
®
delivered approximately 887,000 of these tests. 137,650 AVISE CTD tests were delivered in the year ended December 31, 2023,
representing approximately 2% growth over the same period in 2022. The number of ordering healthcare providers in the quarter
ended December 31, 2023 was 2,383, representing an approximate 2% decrease over the same period in 2022. Revenue growth for
our testing products will depend, in part, on our ability to continue to expand our base of ordering healthcare providers and increase
our penetration with existing healthcare providers.
®
▪ Development of Additional Testing Products. We rely on sales of our AVISE CTD test to generate the significant majority of our
revenue. We expect to continue to invest in research and development in order to develop additional testing products. Our success
in developing new testing products will be important in our efforts to grow our business by expanding the potential market for our
products and diversifying our sources of revenue.
®
▪ Maintain Meaningful Margin. We seek to maintain meaningful margin through a continued focus on increasing operating leverage
through the implementation of certain internal initiatives, such as leveraging validation, utility and reimbursement oriented clinical
studies to facilitate payor coverage of our testing products. We plan to center our efforts around long-term reimbursement and ASP
growth and seek to improve our per test costs by focusing on profitable, core test offerings and limiting fixed costs and overhead.
▪
Timing of Our Research and Development Expenses. We conduct clinical studies to validate our new testing products, as well as
ongoing clinical and outcome studies to further expand the published evidence that supports our commercialized AVISE testing
products. We also expend funds to secure clinical samples that can be used in discovery, product development, clinical validation,
utility and outcome studies. Our spending on experiments and clinical studies may vary substantially from quarter to quarter, and the
timing of these research and development activities is difficult to predict. If a substantial number of clinical samples are obtained in a
given quarter or if a high-cost experiment is conducted in one quarter versus the next, the timing of these expenses will affect our
financial results.
®
▪ How We Recognize Revenue. We record revenue on an accrual basis, using an estimate of the amount that we will ultimately
realize, as determined based on a historical analysis of amounts collected by test and by payor, among other factors. Changes to
such estimates may increase or decrease revenue recognized in future periods.
While each of these areas present significant opportunities for us, they also pose significant risks and challenges that we must address. We
discuss many of these risks, uncertainties and other factors in the section entitled "Risk Factors."
Seasonality
Based on our experience to date, we expect some seasonal variations in our financial results due to a variety of factors, such as: the year-
end holiday period and other major holidays, vacation patterns of both patients and healthcare providers (including medical conferences),
climate and weather conditions in our markets (for example, excess sun exposure can cause flares in SLE), seasonal conditions that may
affect medical practices and provider activity (for example, influenza outbreaks that may reduce the percentage of patients that can be seen)
and other factors relating to the timing of patient benefit changes, as well as patient deductibles and co-insurance limits.
74
Inflationary Environment
The current inflationary environment has resulted in higher prices, which have impacted our costs incurred to generate revenue from our
laboratory testing services, costs to attract and retain personnel, and other operating costs. The severity and duration of the current
inflationary environment remains uncertain and may continue to impact our financial condition and results of operations.
Financial Overview
Revenue
We recognize revenue in accordance with the provisions of ASC Topic 606, Revenue from Contracts with Customers. We record revenue on
an accrual basis, using an estimate of the amount we will ultimately receive, as determined based on a historical analysis of amounts
collected by test and by payor, among other factors. These assessments require significant judgment by management.
To date, we have derived nearly all of our revenue from the sale of our testing products, most of which is attributable to our AVISE CTD test.
We primarily market our testing products to rheumatologists in the United States. The rheumatologists who order our testing products, and to
whom results are reported, are generally not responsible for payment for these products. The parties that pay for these services (payors)
consist of commercial payors (insurance companies, health maintenance organizations, etc.), government payors (primarily Medicare and
Medicaid), client payors (hospitals, other laboratories, etc.), and patient self-pay. Our service is completed upon the delivery of test results to
the prescribing rheumatologists which triggers billing for the service.
®
Our ability to increase our revenue will depend on our ability to further penetrate the market for our current and future testing products and
increase our reimbursement and collection rates for tests delivered.
®
®
In the quarter ended March 31, 2022, CMS agreed, effective April 1, 2022, to recognize a new PLA code for our protein-based test, AVISE
Lupus. Noridian, our MAC, priced this PLA code at $1,085 per test. To determine pricing beyond 2022, CMS recommended crosswalking
AVISE Lupus (0312U) to Vectra (81490) at a rate of $840.65 per test. This pricing was finalized on the 2023 CLFS and is effective from
January 1, 2023 through December 31, 2025. The process for obtaining and maintaining consistent reimbursement for new tests can be
uncertain, lengthy and time consuming. A pricing determination is not synonymous with a coverage determination. Having a price associated
with the PLA code for any particular test does not secure coverage or reimbursement for that PLA code from Medicare or any other third-
party payor.
®
®
®
In an effort to improve transparency regarding Medicare support of AVISE Lupus, on July 29, 2022, we submitted a formal request to
Noridian for coverage of our AVISE Lupus test under the new PLA Code. On September 27, 2022, we received notice that Noridian has
deemed our application for an LCD to be valid. Ultimately receiving a favorable LCD is uncertain and may be time-consuming, resource
intensive and require multiple quarterly or annual periods to complete. In the meantime, we have continued to submit Medicare claims for
AVISE Lupus, appeal denials and respond to requests for additional information. On January 31, 2024, CMS released a coverage article
under which all multi-analyte proteomic testing will be considered within the scope of MolDX and reviewed through their technology
assessment process. The article requires all laboratories furnishing multi-analyte proteomics testing in MolDX jurisdictions to register with the
DEX Diagnostics Exchange Registry and obtain a Z-Code identifier. To determine if the submitted tests are compliant with relevant policy
requirements, these tests will undergo technical assessment by Palmetto GBA as part of the MolDX program. The article listed several such
tests, including the AVISE Lupus test.
®
®
®
We face challenges relating to commercial payor claim processing and revenue. Now that we are billing under our PLA code, we are
experiencing denials due to unfavorable medical policy with certain plans, and we expect this situation to persist.
During the year ended December 31, 2023, we implemented several revenue cycle management initiatives, including among others,
withholding the submission of commercial payor claims for reimbursement until subsequent quarters, increasing appeals efforts and
implementing increases to our patient payment rates. Additionally, in November 2023, we increased the list price billed for our tests. These
ongoing revenue cycle management initiatives aim to optimize our appeals process and the potential for cash collections. We experienced
moderate declines in test volume in the second half of 2023, as rheumatologists and patients adjust to these changes; however, we delivered
137,650 tests for our flagship product, AVISE CTD, in the year ended December 31, 2023 as compared to 135,210 tests for the year ended
December 31, 2022.

Operating Expenses
75
Costs of Revenue
Costs of revenue represents the expenses associated with obtaining and testing patient specimens. The components of our costs of revenue
include materials costs, direct labor, equipment, infrastructure expenses, shipping charges to transport specimens, blood specimen
collections fees, royalties, depreciation and allocated overhead (including rent and utilities).
Each payor, whether commercial, government, or individual, reimburses us at different amounts. These differences can be significant. As a
result, our costs of revenue as a percentage of revenue may vary significantly from period to period due to the composition of payors for each
period's billings. We expect that our costs of revenue will remain relatively consistent year-over-year in the near-term.
Selling, General and Administrative Expenses
Selling, general and administrative expenses consist of personnel costs (including stock-based compensation expense), direct marketing
expenses, accounting and legal expenses, consulting costs, and allocated overhead (including rent, information technology, depreciation and
utilities). We expect that our selling, general and administrative expenses will remain relatively consistent year-over-year in the near-term.
Research and Development Expenses
Research and development expenses include costs incurred to develop our technology, test products and product candidates, in addition to
costs incurred to collect clinical specimens and conduct clinical studies to develop and support those products and product candidates.
These costs consist of personnel-related expenses (including stock-based compensation expense), materials, laboratory supplies, consulting
costs, costs associated with setting up and conducting clinical studies and allocated overhead (including rent and utilities). We expense all
research and development costs in the periods in which they are incurred. We expect that our research and development expenses will
increase year-over-year in the near-term as a result of ongoing clinical studies.
Interest Expense
Interest expense consists of cash and non-cash interest expense associated with our financing arrangements, including the borrowings
under our Amended Loan Agreement with Innovatus. We expect interest expense to remain relatively consistent in the year ending
December 31, 2024 as compared to the year ended December 31, 2023.
Interest Income
Interest income consists of interest income earned on our cash and cash equivalents.
Income Tax (Expense) Benefit
Income taxes include federal and state income taxes in the United States.

Revenue increased $7.0 million, or 15.3%, for the year ended December 31, 2023 compared to the year ended December 31, 2022, primarily
due to improved commercial payor ASP, increased AVISE CTD year-over-year volume and cash collections from tests performed in prior
periods, partially offset by decreased Medicare ASP. The number of AVISE CTD tests delivered increased to 137,650 in the year ended
December 31, 2023 compared to 135,210 tests delivered in the same 2022 period. The AVISE CTD test accounted for 88% and 84% of
revenue for the years ended December 31, 2023 and 2022, respectively. The number of ordering healthcare providers decreased to 2,383 for
the three months ended December 31, 2023 compared to 2,419 in the same 2022 period.
®
®
®
Costs of Revenue
Costs of revenue decreased $1.1 million, or 4.6%, for the year ended December 31, 2023 compared to the year ended December 31, 2022.
This decrease was primarily due to decreases of $0.9 million in materials and supplies expenses resulting from price improvements related to
transition of biomarkers to suppliers with favorable pricing, and $0.2 million in shipping and handling costs. Gross margin as a percentage of
revenue increased to 56.1% for the year ended December 31, 2023 compared to 46.9% for the year ended December 31, 2022.
Selling, General and Administrative Expenses
Selling, general and administrative expenses decreased $4.6 million, or 8.8%, for the year ended December 31, 2023 compared to the year
ended December 31, 2022. This decrease was primarily due to decreases of $6.1 million of personnel costs, including salaries, benefits,
stock-based compensation, severance expenses and other reimbursable employee expenses, as a result of lower headcount, in addition to
decreases of $1.5 million in marketing expenses related to advertising expenses, speaker programs and trade show expenses, $0.3 million in
insurance expenses, $0.2 million in third-party billing expenses and $0.1 million in legal expenses. These decreases were partially offset by
the recognition of a $1.5 million loss on the disposal of assets primarily related to an assignment of a lease, in addition to an increases in
expenses related to bonuses of $1.3 million, facilities and allocated overhead expenses of $0.5 million and commissions of 0.3 million.
Research and Development Expenses
Research and development expenses decreased $5.0 million, or 50.7%, for the year ended December 31, 2023 compared to the year ended
December 31, 2022. This decrease was primarily due to decreases of $2.7 million of personnel costs, including salaries, benefits and stock-
based compensation, as a result of lower headcount, decreases related to lab supplies expenses of $1.0 million, collaboration expenses of
$0.5 million, clinical study expenses of $0.3 million, and professional service fees of $0.2 million, in addition to a long-lived assets impairment
charge of $0.4 million for the year ended December 31, 2022.
77
Goodwill Impairment
As part of our annual goodwill impairment assessment in the fourth quarter of 2022, we determined that the sustained decrease in our market
capitalization constituted an indicator of impairment and as a result, a quantitative goodwill impairment test was completed as of December
31, 2022. This analysis identified an impairment of $5.5 million related to our goodwill.
Interest Expense
Interest expense decreased $0.1 million for the year ended December 31, 2023 compared to the year ended December 31, 2022 due to a
lower principal balance on the company's Amended Loan Agreement.
Interest Income
Interest income increased $0.7 million for the year ended December 31, 2023 compared to the year ended December 31, 2022 due to higher
money market and certificate of deposit interest rates in 2023 compared to 2022.
Income Tax (Expense) Benefit
Income tax benefit increased $0.3 million for the year ended December 31, 2023 compared to the year ended December 31, 2022, primarily
due to the release of a valuation allowance.
Liquidity and Capital Resources
We have incurred net losses since our inception. For the years ended December 31, 2023 and 2022, we incurred a net loss of $23.7 million
and $47.4 million, respectively, and we expect to incur additional losses in future periods. To date, we have generated only limited revenue,
and we may never achieve revenue sufficient to offset our expenses. As of December 31, 2023, we had an accumulated deficit of
$279.2 million and cash and cash equivalents of $36.5 million. Cash in excess of immediate requirements is invested in accordance with our
investment policy, primarily with a view to liquidity and capital preservation. Currently, our funds are held in cash, money market funds and
certificates of deposit.
Since becoming a public company, our primary sources of capital have been cash inflows from product sales, sales of our common stock
and, to a lesser extent, borrowings under our 2017 Term Loan. In April 2023, we further amended the 2017 Term Loan, pursuant to which we
prepaid $10.0 million of principal and amended additional terms of the agreement. See Note 4, Borrowings, to our audited financial
statements included in this Annual Report on Form 10-K for additional information.
Our obligations under the Amended Loan Agreement are secured by a security interest in substantially all of our assets, including our
intellectual property. The Amended Loan Agreement contains customary conditions to borrowing, events of default, and covenants, including
covenants requiring us to maintain minimum liquidity of $2.0 million, covenants to achieve certain minimum amounts of revenue, and
covenants limiting our ability to dispose of assets, undergo a change in control, merge with or acquire other entities, incur debt, incur liens,
pay dividends or other distributions to holders of our capital stock, repurchase stock and make investments, in each case subject to certain
exceptions. Per the Amended Loan Agreement, we are not required to comply with the revenue covenant for any quarter during which we
maintain a minimum aggregate cash balance equal to fifty percent of the aggregate principal amount of the 2017 Term Loan funded
(excluding any capitalized interest paid-in-kind) at all times during such quarter. The consequences of failing to achieve the performance
covenants, when applicable, will be cured if (i) within thirty days of failing to achieve the performance covenant, we submit a new Board
approved financial plan to Innovatus under which we are expected to break even on a cash flow basis prior to the maturity date, and (ii)
within thirty days of the submission of such financial plan, we issue additional equity securities or subordinated debt with net proceeds
sufficient to fund any cash flow deficiency generated from operations, as defined in the Amended Loan Agreement. As of December 31,
2023, we were in compliance with all covenants of the Amended Loan Agreement with Innovatus. In addition, upon the occurrence of an
event of default, Innovatus, among other things, can declare all indebtedness due and payable immediately, which would adversely impact
our liquidity and reduce the availability of our cash flows to fund working capital needs, capital expenditures and other general corporate
purposes.
On November 17, 2023, we filed a registration statement on Form S-3 (Shelf Registration Statement) covering the offering, from time to time,
of up to $150.0 million of common stock, preferred stock, debt securities, warrants and units, all of which remain available for sale at
December 31, 2023.
78
On September 15, 2022, the Company entered into a sales agreement (the Sales Agreement) with TD Cowen as sales agent, pursuant to
which the Company may offer and sell, from time to time, shares of Company common stock having an aggregate offering price of up to
$50.0 million. The Sales Agreement was amended in November 2023 in connection with the filing of the Form S-3 discussed above. The
Company is not obligated to sell any shares of Company common stock in the offering and, as of December 31, 2023, the Company had not
sold any shares of its common stock pursuant to the Sales Agreement.
Our ability to utilize the $150 million of capacity remaining under our Shelf Registration Statement, including the $50.0 million of capacity
remaining under our at the market offering sales agreement is limited by our compliance with the baby shelf rules (as defined below). As of
the filing of this Annual Report on Form 10-K, our public float is less than $75 million, and under SEC regulations, for so long as our public
float remains less than $75 million, the amount we can raise through primary public offerings of securities in any twelve-month period using
shelf registration statements subject to Instruction I.B.6. to Form S-3 is limited to an aggregate of one-third of our public float, which is
referred to as the “baby shelf rules.” As of February 15, 2024, our public float was approximately $29.7 million, based on 12,916,064 shares
of outstanding common stock held by non-affiliates and at a price of $2.30 per share, which was the last reported sale price of our common
stock on the Nasdaq Capital Market on January 30, 2024.
Funding Requirements
Our primary use of cash is to fund our operations as we continue to grow our business. We expect to continue to incur operating losses in the
near term. In the short-term, we expect costs of revenue and selling, general and administrative expenses to remain relatively consistent. We
expect research and development expenses to increase in the short-term as a result of ongoing clinical studies. We believe we have
sufficient laboratory capacity to support increased test volume. Cash used to fund operating expenses is impacted by the timing of when we
pay expenses, as reflected in the change in our outstanding accounts payable and accrued expenses.
We expect that our near- and longer-term liquidity requirements will continue to consist of working capital and general corporate expenses
associated with the growth of our business, including payments we may be required to make upon the achievement of previously negotiated
milestones associated with intellectual property we have licensed, payments related to non-cancelable purchase obligations with one supplier
for reagents, payments related to our principal and interest under our long term borrowing arrangements, payments for operating leases
related to our office and laboratory space in Vista, California and our office space in Carlsbad, California, and payments for finance leases
related to our laboratory equipment (see Note 4, Borrowings, and Note 6, Commitments and Contingencies, to our audited financial
statements included in this Annual Report on Form 10-K). Based on our current business plan, we believe that our existing cash and cash
equivalents and our anticipated future revenue, will be sufficient to meet our anticipated cash requirements for at least the next 12 months
from the date of this filing.
Our estimate of the period of time through which our financial resources will be adequate to support our operations is a forward-looking
statement and involves risks and uncertainties. Actual results could vary as a result of a number of factors, including:

our ability to achieve sufficient market acceptance, coverage and adequate reimbursement from third-party payors and adequate
market share and revenue for our testing products;
our ability to maintain and grow sales of our AVISE testing products, as well as the costs associated with conducting clinical studies
to demonstrate the utility of our products and support reimbursement efforts;
®
fluctuations in working capital;
the costs of developing our product pipeline, including the costs associated with conducting our ongoing and future validation, utility
and outcome studies as well as the success of our development efforts; and
the extent to which we establish additional partnerships or in-license, acquire or invest in complementary businesses or products as
well as the success of our existing partnerships and/or in-licenses.
Until such time, if ever, as we can generate revenue to support our costs structure, we expect to finance our operations through equity
offerings, debt financings or other capital sources, including potentially collaborations, licenses and other similar arrangements. Debt
financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as
incurring additional debt, making capital expenditures or declaring dividends. To the extent that we raise additional capital through the sale of
equity or convertible debt securities, the ownership interest of our stockholders may be diluted, and the terms of these
79
securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. If additional funding is
required or desired, there can be no assurance that additional funds will be available to us on acceptable terms on a timely basis, if at all, or
that we will generate sufficient cash from operations to adequately fund our operating needs or achieve or sustain profitability. If we are
unable to raise additional capital or generate sufficient cash from operations to adequately fund our operations, we will need to delay, reduce
or eliminate some or all of our research and development programs, product portfolio expansion plans or commercialization efforts. Doing so
will likely have an unfavorable effect on our ability to execute on our business plan and could have a negative impact on our commercial and
strategic relationships. If we cannot expand our operations or otherwise capitalize on our business opportunities because we lack sufficient
capital, our business, financial condition, and results of operations could be adversely affected.

disposal of assets primarily related to the assignment of a lease, non-cash lease expenses and non-cash interest and (ii) changes in our net
operating assets of $0.3 million primarily related to net increases in prepaid expenses and other current assets and accounts receivable, and
net decreases in operating lease liabilities, partially offset by net increases in accrued and other current liabilities.
Net cash used in operating activities for the year ended December 31, 2022 was $32.1 million and primarily resulted from (i) our net loss of
$47.4 million adjusted for non-cash charges of $13.6 million related to stock-based compensation, depreciation, amortization, non-cash
interest and deferred income taxes and (ii) changes in our net operating assets of $1.7 million primarily related to net increases in accounts

increases in accrued liabilities and other current liabilities.
Cash Flows from Investing Activities
Net cash used in investing activities for the year ended December 31, 2023 and 2022 was $0.8 million and $4.3 million, respectively, and was
primarily due to net purchases of property and equipment.
Cash Flows from Financing Activities
Net cash used in financing activities for the year ended December 31, 2023 was $10.6 million, primarily consisting of principal payments on
the Amended Loan Agreement, finance lease obligations and notes payable, partially offset by the proceeds from the Exagen Inc. 2019
Employee Stock Purchase Plan (the ESPP) purchases.
Critical Accounting Estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our audited financial statements,
which have been prepared in accordance with accounting principles generally accepted in United States of America (GAAP). The preparation
of these audited 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 audited 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
80
apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions and any such
differences may be material. We believe the following accounting estimates are the most critical to us, in that they require our most difficult,
subjective or complex judgments in the preparation of our financial statements. For further information, see Note 2, Summary of Significant
Accounting Policies, to our Financial Statements, which outlines our application of significant accounting policies.
Revenue Recognition
To date, substantially all of our revenue has been derived from sales of our testing products. We primarily market our testing products to
rheumatologists and their physician assistants in the United States. The healthcare professionals who order our services and to whom test
results are reported are generally not responsible for payment for these services. The parties that pay for these services consist of
commercial payors, government payors (primarily Medicare and Medicaid), client payors (hospitals, other laboratories, etc.) and patient self-
pays.
Payors are billed at our list price. Net revenues recognized consist of amounts billed net of allowances for differences between amounts
billed and the estimated consideration we expect to receive from such payors. We follow a standard process, which considers historical
denial and collection experience, insurance reimbursement policies and other factors, to estimate allowances and implicit price concessions,
recording adjustments in the current period as changes in estimates. Further adjustments to the allowances, based on actual receipts, are
recorded upon settlement. The transaction price is estimated using an expected value method on a portfolio basis. Our portfolios are grouped
per payor (each individual third-party insurance, Medicare, Medicaid, client payors, patient self-pay, etc.) and per test basis.
Collection of our net revenues from payors is normally a function of providing complete and correct billing information to the healthcare
insurers and generally occurs within 30 to 90 days of billing.
The process for estimating revenues and the ultimate collection of accounts receivable involves significant judgment and estimation by
management. We continually assess the state of our cash collections in order to identify areas of risk and opportunity that allow us to
appropriately estimate receivables and revenue. Should we later determine the judgements underlying estimated collections change, our
financial results could be impacted in future periods. Included in revenues for the years ended December 31, 2023 and 2022 was a net
revenue increase of $3.4 million and a net revenue decrease of $2.4 million, respectively, associated with changes in estimated variable
consideration related to performance obligations satisfied in previous periods.
Stock-Based Compensation
We recorded stock-based compensation expense of approximately $3.6 million and $4.7 million for the years ended December 31, 2023 and
2022, respectively. We expect to continue to grant stock options, restricted stock units (RSUs) and other equity-based awards in the future
and to the extent that we do, our stock-based compensation expense recognized in future periods will likely increase. For stock options and
purchase rights granted under the ESPP, we estimate the grant date fair value using the Black-Scholes option-pricing valuation model. For
RSUs, we use the closing price of our common stock on the date of grant to determine the fair value.
The Black-Scholes option pricing model requires the use of assumptions, which determine the fair value of stock-based awards. If we had
made different assumptions, our stock-based compensation expense, net loss and net loss per share attributable to common stockholders
could have been significantly different. See Note 2, Summary of Significant Accounting Policies, and Note 9, Stock Option Plan, to our
audited financial statements in this Annual Report on Form 10-K for information concerning certain of the specific assumptions we used in
applying the Black-Scholes option pricing model to determine the estimated fair value of our stock options granted and purchases under our
ESPP rights in the years ended December 31, 2023 and 2022.
Recent Accounting Pronouncements
See Note 2, Recent Accounting Pronouncements, of our annual financial statements.
JOBS Act Accounting Election
The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for an "emerging growth company." The
JOBS Act permits an "emerging growth company" like us to take advantage of an extended transition period to comply with new or revised
accounting standards applicable to public companies. We have elected to use this extended transition period under the JOBS Act until the
earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition
period provided in
81
the JOBS Act. As a result, our audited financial statements may not be comparable to companies that comply with new or revised accounting
pronouncements as of public company effective dates.
We will remain an emerging growth company until the last day of our fiscal year following the fifth anniversary of the date of the first sale of
our common equity securities pursuant to an effective registration statement under the Securities Act, which will occur in 2024. However, if
certain events occur prior to the end of this five-year period, including if we become a "large accelerated filer" as defined in Rule 12b-2 under
the Exchange Act, our annual gross revenues exceed $1.235 billion or we issue more than $1.0 billion of non-convertible debt in any three-
year period, we will cease to be an emerging growth company prior to this anniversary.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures
Item 9A. Controls and Procedures.
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports that we
file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules
and forms, and that the information required to be disclosed by us in such reports is accumulated and communicated to our management,
including our principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely
decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that
any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of
achieving the desired control objectives. In reaching a reasonable level of assurance, management necessarily was required to apply its
judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also
is 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, control may become inadequate because of changes in
conditions, or the degree of compliance with policies or procedures may deteriorate.
Our management, with the participation of our principal executive officer and our principal financial officer, evaluated, as of the end of the
period covered by this Annual Report on Form 10-K, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-
15(e) and 15d-15(e) under the Exchange Act). Based on that evaluation, our principal executive officer and principal financial officer have
concluded that as of December 31, 2023, our disclosure controls and procedures were effective at the reasonable assurance level.
Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable
assurance of achieving their objectives and our management necessarily applies its judgement in evaluating the cost-benefit relationship of
possible controls and procedures.
Management's Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-
15(f) and 15d-15(f) under the Exchange Act. Internal control over financial reporting is a process designed under the supervision and with the
participation of our management, including our principal executive officer and principal financial officer, to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Our
internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets, (ii) provide reasonable assurance that
transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and
expenditures are being made only in accordance with authorizations of our management and directors, and (iii) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material
effect on the financial statements. Because of its inherent limitations, internal controls over financial reporting may not prevent or detect all
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. Therefore,
even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and
presentation.
As of December 31, 2023, our management assessed the effectiveness of our internal control over financial reporting using the criteria set
forth by the Committee of Sponsoring Organizations of the Treadway Commission in
83
Internal Control-Integrated Framework (2013 framework). Based on this assessment, our management concluded that, as of December 31,
2023, our internal control over financial reporting was effective.
Remediation of Previously Disclosed Material Weaknesses
On November 13, 2022, management and the Audit Committee determined that we made certain errors in revenue resulting from erroneous
and duplicate billings related to changes in billing practices. The errors were due to the inadequate design, implementation and precision of
internal controls and procedures to evaluate and monitor the accounting for revenue recognition. As a result, revenue and accounts
receivable were overstated and other liabilities was understated for the quarter and year to date periods ended June 30, 2022.
We concluded that these were material errors in the financial statements requiring a restatement of the Form 10-Q for the three and six
months ended June 30, 2022. Accordingly, management determined that this control deficiency constituted a material weakness as of
December 31, 2022.
In response to the material weaknesses, and as previously disclosed in Item 9A of our annual report on Form 10-K for the year ended
December 31, 2022, we implemented a remediation plan which included, but was not limited to, evaluating the staffing level, skills and
qualification of accounting department personnel, enhancement of our existing control structure and processes for revenue recognition and
improving the detailed review process of our revenue recognition models. The enhancements made to our control environment were in place
as of December 31, 2023, and based on the evaluation of relevant internal controls, management has concluded that the material
weaknesses previously identified have been remediated as of December 31, 2023.
Attestation Report of the Registered Public Accounting Firm
This Annual Report on Form 10-K does not include an attestation report of our registered public accounting firm due to an exemption
provided by the JOBS Act for "emerging growth companies."
Changes in Internal Control Over Financial Reporting
Other than the remediation of the material weakness discussed above, there have been no changes in our internal control over financial
reporting during the three months ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our
internal control over financial reporting.
Inherent Limitations on Effectiveness of Controls and Procedures
Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable
assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of
possible controls and procedures.

Report of Independent Registered Public Accounting Firm
Shareholders and Board of Directors
Exagen Inc.
Vista, California
Opinion on the Financial Statements
We have audited the accompanying balance sheets of Exagen Inc. (the "Company”) as of December 31, 2023 and 2022, the related
statements of operations, stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the
“financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company at
December 31, 2023 and 2022, and the results of its operations and its cash flows for the years then ended, in conformity with accounting
principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the
Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting
Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S.
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The
Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our
audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion
on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or
fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the
amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits
provide a reasonable basis for our opinion.
/s/ BDO USA, P.C.
We have served as the Company’s auditor since 2017.

Exagen Inc.
Notes to Financial Statements
Note 1. Organization
Description of Business
Exagen Inc. (the Company) is a commercial-stage diagnostics company which exists to provide clarity in autoimmune disease decision
making with the goal of improving patients' clinical outcomes.
Liquidity
The Company has incurred recurring losses and negative cash flows from operating activities since inception. The Company anticipates that
it will continue to incur net losses into the foreseeable future. At December 31, 2023, the Company had cash and cash equivalents of $36.5
million and had an accumulated deficit of $279.2 million. Since inception, the Company has financed its operations primarily through a
combination of equity financings, debt financing arrangements, and revenue from sales of the Company's products. Based on the Company's
current business plan, management believes that its existing capital resources will be sufficient to fund the Company's obligations for at least
twelve months following the issuance of these financial statements.
To execute its business plans, the Company may need additional funding to support its continuing operations and pursue its growth strategy.
Until such time as the Company can achieve significant cash flows from operations, if ever, it expects to finance its operations through the
sale of its stock, debt financings or other strategic transactions. Although the Company has been successful in raising capital in the past,
there is no assurance that it will be successful in obtaining such additional financing on terms acceptable to the Company, if at all. The terms
of any financing may adversely affect the holdings or the rights of the Company's stockholders. If the Company is unable to obtain funding,
the Company could be forced to delay, reduce or eliminate some or all of its programs, product portfolio expansion plans or
commercialization efforts, which could have a material adverse effect on the Company's business, operating results and financial condition
and the Company's ability to achieve its intended business objectives.
Note 2. Summary of Significant Accounting Policies
Basis of Presentation and Use of Estimates
The Company's financial statements are prepared in accordance with accounting principles generally accepted in the United States of
America (GAAP). The preparation of the accompanying financial statements requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial
statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could materially differ from those
estimates.
Significant estimates and assumptions made in the accompanying financial statements include, but are not limited to revenue recognition, the
estimated incremental borrowing rate for the determination of the Company's operating lease right-of-use (ROU) assets and the
recoverability of its long-lived assets and net deferred tax assets (and related valuation allowance). The Company evaluates its estimates
and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts
and circumstances dictate. Actual results could materially differ from those estimates.
Concentration of Credit Risk and Other Risk and Uncertainties
Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents and accounts
receivable. Substantially all the Company's cash and cash equivalents are held at one financial institution that management believes is of
high credit quality. Such deposits may, at times, exceed federally insured limits. The Company has not experienced any losses on its cash or
cash equivalents.
Significant payors and customers are those which represent more than 10% of the Company's total revenue or accounts receivable balance
at each respective balance sheet date. For each significant payor and customer, revenue as a percentage of total revenue and accounts
receivable as a percentage of total accounts receivable are as follows:

For the years ended December 31, 2023 and 2022, approximately 88% and 84%, respectively, of the Company's revenue was related to the
AVISE CTD test.
®
The Company is dependent on key suppliers for certain laboratory materials. For each of the years ended December 31, 2023 and 2022,
approximately 96% of the Company's diagnostic testing supplies were purchased from two suppliers. An interruption in the supply of these
materials would impact the Company's ability to perform testing services.

The Company considers all highly-liquid investments purchased with a remaining maturity date of three months or less upon acquisition to be
cash equivalents. These investments are stated at cost, which approximates fair value.
The Company has an arrangement with a financial institution with which it has an existing banking relationship, whereby in exchange for the
issuance of corporate credit cards, the Company agreed to obtain a certificate of deposit with this financial institution in the amount of $0.2
million as collateral for the balances borrowed on these cards. The Company has classified the value of this certificate of deposit (including
all interest earned thereon) within other assets in the accompanying balance sheets. The Company has the right to terminate the credit card
program at any time. Upon termination of the credit card program and repayment of all outstanding balances owed, the Company may
redeem the certificate of deposit (and all interest earned thereon).

Property and Equipment
Property and equipment are stated at cost, net of depreciation and amortization. Depreciation is computed using the straight-line method
over the estimated useful lives of the assets, generally between three and five years. Leasehold improvements are amortized on a straight-
line basis over the lesser of the estimated useful life or the remaining term of the related lease. Maintenance and repairs are charged to
expense as incurred, and improvements and betterments are capitalized. When assets are retired or otherwise disposed of, the cost and
accumulated depreciation are removed from the balance sheet and any resulting gain or loss is reflected in operating expenses in the
statements of operations in the period realized.
Long-lived Assets
The Company’s long-lived assets are comprised principally of its property and equipment and operating lease assets. The Company
amortizes all finite lived intangible assets over their respective estimated useful lives. Operating lease assets are amortized over the term of
the leases. In considering whether long-lived assets are impaired, the Company combines its intangible assets and other long-lived assets
into groupings, a determination which is made principally on the basis of whether the assets are specific to a particular test offered or
technology being developed. If the Company identifies a change in the circumstances related to its long-lived assets that indicates the
carrying value of any such asset may not be recoverable, the Company will perform an impairment analysis. A long-lived asset is deemed to
be impaired when the undiscounted cash flows expected to be generated by the asset (or asset group) are less than the asset’s carrying
amount. Management’s estimates of future cash flows are impacted by projected test volume and levels of reimbursement, as well as
expectations related to the future cost structure of the entity. Any required impairment loss would be measured as the amount by which the
asset’s carrying value exceeds its fair value, and would be recorded as a reduction in the carrying value of the related asset and a charge to
operating expense.
Goodwill
The Company operates in a single operating segment and reporting unit for the measurement of goodwill. Goodwill was reviewed for
impairment annually (during the fourth quarter) or more frequently if indicators of impairment existed. The Company would first assess
qualitative factors to determine whether it was more likely than not that the fair value of the reporting unit was less than its carrying amount
as a basis for determining whether it was necessary to perform a quantitative assessment. If, after assessing qualitative factors, the
Company determined it was not more likely than not that the fair value of a reporting unit was less than its carrying amount, then performing
a quantitative assessment was unnecessary. If deemed necessary, a quantitative assessment compared the fair value of the reporting unit
with its carrying amount, including goodwill. If the fair value of the reporting unit exceeded its carrying amount, goodwill was not considered
impaired; otherwise, an impairment loss was recorded.
Leases
The Company categorizes leases at their commencement as either operating or finance leases. The Company recognizes operating lease
ROU assets and operating lease liabilities for each lease arrangement identified. Lease liabilities are recorded at the present value of future
lease payments discounted using the Company's incremental borrowing rate for the lease established at the commencement date. The
incremental borrowing rate is the rate of interest the Company would have to pay to borrow, on a collateralized basis over a similar term and
in a similar economic environment, an amount equal to the total lease payments. The Company primarily considers industry data, its credit
rating and the lease term to determine its incremental borrowing rate. ROU assets are measured at the amount of the lease liability plus any
initial direct costs, less any lease incentives received before commencement. Lease expense is recognized as a single lease cost over the
lease term on a straight-line basis. The Company has elected not to apply the recognition requirements to short-term leases and not to
separate non-lease components from lease components for its leases.
Clinical Studies
From time to time, the Company engages in efforts to scientifically measure and document the application and efficacy of its various testing
products. These arrangements typically require the Company to pay a fee to a third-party scientific investigator (usually a physician or
research institution) for each subject enrolled in a clinical study, and the Company accrues expenses based on estimated progress of
services performed, including actual level of subjects enrolled and progress of the clinical studies. Payments made prior to the completion of
clinical study services are capitalized as a prepaid expense. The prepaid amounts are expensed as the related goods are delivered or the
services are performed, or when it is no longer expected that the goods will be delivered or the
F-9
services rendered. Expenses associated with clinical study activities are recorded in research and development expenses in the
accompanying statement of operations.
Revenue Recognition
Substantially all of the Company's revenue has been derived from sales of its testing products and is primarily comprised of a high volume of
relatively low-dollar transactions. The Company primarily markets its testing products to rheumatologists and their physician assistants in the
United States. The healthcare professionals who order the Company's testing products and to whom test results are reported are generally
not responsible for payment for these products. The parties that pay for these services (each, a payor) consist of commercial payors
(healthcare insurers), government payors (primarily Medicare and Medicaid), client payors (i.e., hospitals, other laboratories, etc.) and patient
self-pay.
The Company recognizes revenue in accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with
Customers (ASC 606) and follows a five-step process to determine the amount and timing of revenue recognized: (1) identify the contract
with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction
price to performance obligations in the contract, and (5) recognize revenue when (or as) the performance obligation is satisfied. The
Company's service is a single performance obligation that is completed upon the delivery of test results to the prescribing physician which
triggers revenue recognition.
Payors are generally billed at the Company's list price, unless a separate pricing contract is in place. Net revenues recognized consist of
amounts billed net of allowances for differences between amounts billed and the estimated consideration the Company expects to receive
from such payors. The process for estimating revenues and the ultimate collection of accounts receivable involves significant judgment and
estimation. The Company follows a standard process, which considers historical denial and collection experience, insurance reimbursement
policies and other factors, to estimate allowances and implicit price concessions. Adjustments are recorded in the current period as changes
in estimates occur. Further adjustments to the allowances, based on actual receipts, are recorded upon settlement. Included in revenues for
the years ended December 31, 2023 and 2022 was a net revenue increase of $3.4 million and a net revenue decrease of $2.4 million,
respectively, associated with changes in estimated variable consideration related to performance obligations satisfied in previous periods.
The transaction price is estimated using an expected value method on a portfolio basis.
Variable consideration is included in the transaction price only to the extent it is probable that a significant reversal in the amount of
cumulative revenue recognized will not occur when the uncertainties with respect to the amount are resolved. The Company's portfolios are
grouped per payor (i.e. each individual commercial payor, Medicare, Medicaid, client payors, patient self-pay, etc.) and per test.
Consideration may be constrained and excluded from the transaction price in situations where there is no contractually agreed upon
reimbursement coverage or in absence of a predictable pattern and history of collectability with a payor. Accordingly, in such situations
revenues are recognized on the basis of actual cash collections. Additionally, from time to time, the Company may issue refunds to payors for
overpayments or amounts billed in error. Any refunds are accounted for as reductions in revenues in the statement of operations as an
element of variable consideration. The estimated expected refunds are accrued as a liability on the Company’s balance sheet.
Collection of the Company's net revenues from payors is normally a function of providing complete and correct billing information, along with
any requested medical or other claims-related information to the healthcare insurers. This generally occurs within 30 to 90 days of billing,
however, the amount and timing of any reimbursements or collections for our billed tests may vary by payor and other circumstances.
Contracts do not contain significant financing components based on the typical period of time between performance of services and
collection of consideration.
Accounts Receivable and Allowance for Credit Losses
We accrue an allowance for credit losses against our accounts receivable based on management’s current estimate of amounts that will not
be collected. Management’s estimates are typically based on historical loss information adjusted for current conditions. We generally do not
perform evaluations of the financial condition of our customers and generally do not require collateral. The allowance for credit losses was
zero as of December 31, 2023. There was no allowance for credit losses recognized as of December 31, 2022. Adjustments for implicit price
concessions attributable to variable consideration, as discussed above, are incorporated into the measurement of the accounts receivable
balances and are not part of the allowance for credit losses. Accounts receivable was $6.6 million, $6.1 million, $9.7 million for the years
ended December 31, 2023, 2022 and 2021, respectively.
Research and Development
F-10
Costs associated with research and development activities are expensed as incurred and include, but are not limited to, personnel-related
expenses, including stock-based compensation expense; materials; laboratory supplies; consulting costs; costs associated with setting up
and conducting clinical studies; depreciation; amortization and allocated overhead, including rent and utilities.
Advertising and Marketing Costs
Costs associated with advertising and marketing activities are expensed as incurred. Total advertising and marketing costs were
approximately $1.5 million and $3.0 million for the years ended December 31, 2023 and 2022, respectively, and are included in selling,
general and administrative expenses in the accompanying statements of operations.
Shipping and Handling Costs
Costs incurred for shipping and handling are included in costs of revenue in the accompanying statements of operations and were
approximately $2.5 million and $2.7 million for the years ended December 31, 2023 and 2022, respectively.
Stock-Based Compensation
The Company recognizes compensation expense for all stock-based awards to employees and directors based on the grant-date estimated
fair values over the requisite service period of the awards (usually the vesting period) on a straight-line basis. The fair value of stock options
and purchases under the Company's 2019 Employee Stock Purchase Plan (ESPP) rights is determined using the Black-Scholes-Merton
(BSM) option pricing model, which requires management to make certain assumptions regarding a number of complex and subjective
variables. Equity award forfeitures are recorded as they occur.
The BSM option pricing model incorporates various inputs, including the fair value of the Company's common stock, expected volatility,
expected term and risk-free interest rates. Volatility is based on the Company's historical calculated volatility since being publicly traded. The
weighted-average expected term of options was calculated using the simplified method, as we have concluded that our stock option exercise
history does not provide a reasonable basis upon which to estimate the expected term. The risk-free interest rate for periods within the
contractual term of the option is based on the U.S. Treasury yield in effect at the time of grant. The dividend yield is zero, as the Company
has never declared or paid dividends and has no plans to do so in the foreseeable future.
The fair value of each restricted stock unit (RSU) is determined on the grant date using the closing price of the Company's common stock on
that date. The Company's RSUs generally vest in equal annual installments over four years from the date of grant or, for grants to new hires,
date of hire. Vesting of RSUs is subject to the holder's continued service with the Company. The Company issues new shares to satisfy
RSUs upon vesting.
Comprehensive Loss
Comprehensive loss is defined as a change in equity of a business enterprise during a period, resulting from transactions from nonowner
sources. There have been no items qualifying as other comprehensive loss and, therefore, for all periods presented, the Company's
comprehensive loss was the same as its reported net loss.
Income Taxes
The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and
liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method,
deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax basis of assets and
liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on
deferred tax assets and liabilities is recognized as an expense in the period that includes the enactment date.
The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be
realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of
existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If
management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded
amount, management would adjust the deferred tax asset valuation allowance, which would reduce the provision for income taxes.
F-11
The Company records uncertain tax positions on the basis of a two-step process whereby (i) management determines whether it is more
likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that
meet the more-likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50% likely to
be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized
tax benefits within income tax expense. Any accrued interest and penalties are included within the related tax liability.
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 common shares outstanding during the period. Diluted net loss per share attributable to common
stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common stock
equivalents outstanding for the period determined using the treasury-stock and if-converted methods. The weighted-average number of
shares used to compute basic and diluted shares includes shares issuable upon the exercise of pre-funded warrants at a nominal price.
Potentially dilutive common stock equivalents are comprised of warrants for the purchase of common stock, stock options, RSUs outstanding
under the Company's 2019 Incentive Award Plan (the 2019 Plan) and shares of the Company's common stock pursuant to the ESPP. For
each of the years ended December 31, 2023 and 2022, there is no difference in the number of shares used to calculate basic and diluted
shares outstanding as the inclusion of the potentially dilutive securities would be antidilutive.
Potentially dilutive securities not included in the calculation of diluted net loss per share, because to do so would be anti-dilutive, are as
follows (in common stock equivalent shares):

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for
evaluation by the chief operating decision-maker in making decisions regarding resource allocation and assessing performance. The
Company views its operations as, and manages its business in, one operating segment.
Recent Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB), or other standard
setting bodies and adopted by the Company as of the specified effective date. Under the Jumpstart Our Business Startups Act of 2012
(JOBS Act), the Company meets the definition of an emerging growth company. The Company has elected to use the extended transition
period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act. Unless otherwise discussed,
Accounting Standards Updates (ASU) not included in the Company’s disclosures were assessed and determined to be either not applicable
or are not expected to have a material impact on the Company’s financial statements or disclosures.
In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
(ASU 2023-07), which requires public entities to disclose significant segment expenses that are regularly provided to the Chief Operating
Decision Maker (CODM) and details of how the CODM uses financial reporting to assess the performance of a segment. ASU 2023-07 is
effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with
early adoption permitted. This ASU will likely result in additional required disclosure when adopted. The Company is currently evaluating the
provisions of this ASU and the impact on its financial statements and related disclosures.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09),
which requires additional income tax disclosures in the rate reconciliation table for federal, state and foreign income taxes, in addition to more
details about the reconciling items in some categories
F-12
when items meet a certain quantitative threshold. ASU 2023-09 is effective for annual periods beginning after December 15, 2024 with early
adoption permitted. The Company is currently evaluating the impact of this standard, but does not expect that it will have a material impact
on its financial statements.
Recently Adopted Accounting Standards
In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial
Instruments, which requires the measurement of expected credit losses (based on historical experience, current conditions and reasonable
forecasts) for financial instruments (such as accounts receivable) held at the reporting date which are carried at amortized cost. The main
objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on
financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. In November 2018, the FASB
issued ASU 2018-19, Codification Improvements to Topic 326, Financing Instruments-Credit Losses, which included an amendment of the
effective date for nonpublic entities. The Company adopted this pronouncement on January 1, 2023. The adoption did not have material
impact on its financial statements.
In August 2020, the FASB issued ASU 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). ASU 2020-06 eliminates the beneficial conversion and cash conversion
accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently
accounted for as derivatives because of specific settlement provisions. In addition, ASU 2020-06 modifies how particular convertible
instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. The amendments in ASU 2020-
06 are effective for smaller reporting companies as defined by the SEC for fiscal years beginning after December 15, 2023, including interim
periods within those fiscal years. The Company early adopted ASU 2020-06 as of January 1, 2023. The adoption did not have an impact on
its financial statements.

Depreciation and amortization expense for the years ended December 31, 2023 and 2022, was approximately $2.2 million and $1.6 million,
respectively. At December 31, 2023 and 2022, the gross book value of assets under finance leases was $2.5 million and $2.8 million,
respectively, and is classified in "Laboratory equipment" in the table above.

Loss on Lease Assignment
On October 24, 2023, the Company entered into an assignment and assumption (the Assignment and Assumption Agreement) of the
Company’s previously executed lease agreement with Liberty Vista, LP (formerly known as Geiger Court, LLC) and Mindera Corporation
(Mindera), pursuant to which the Company assigned to Mindera the lease of a building located adjacent to the Company's headquarters in
Vista, CA. Under the terms of the Assignment and Assumption Agreement, Mindera assumed all obligations under the lease, effective
October 31, 2023. As a result of the lease assignment, the Company derecognized the remaining balances related to the associated
operating lease ROU asset of $0.7 million, operating lease liability of $0.8 million and leasehold improvements of $1.6 million, resulting in a
$1.5 million loss on lease assignment. The loss was classified within selling, general and administrative expenses in the accompanying
statements of operations.
Impairment of Long-Lived Assets and Goodwill
During the year ended December 31, 2022, the Company recorded an impairment charge of $0.4 million related to previously capitalized
equipment used in research and development activities that were halted in the fourth quarter of 2022. The impairment charge was classified
within research and development expenses in the accompanying statements of operations.
During the year ended December 31, 2022, the Company also determined that a sustained decrease in its market capitalization constituted
an indicator of impairment of goodwill and as a result, instead of performing a qualitative test, the Company chose to proceed directly to
performing a quantitative test during the fourth quarter. The Company determined the fair value of the reporting unit using the discounted
cash flow (DCF) method, which is considered a Level 3 measurement. In applying the DCF method, cash flows are estimated for a five-year
financial forecast developed by management. A terminal value, which represents the value of additional cash flows into perpetuity, is also
calculated. Cash flows are then discounted to present value at a discount rate commensurate with their risk. Based on this analysis, the
carrying value of the reporting unit was in excess of the fair value and the goodwill was fully impaired. During the year ended December 31,
2022, the Company recorded a goodwill impairment charge of $5.5 million.

In September 2017, the Company executed a term loan agreement (the 2017 Term Loan) with Innovatus Life Sciences Lending Fund I, LP
(Innovatus), as amended (the Amended Loan Agreement), pursuant to which the Company borrowed $25.0 million. At December 31, 2023,
no additional amounts remained available to borrow under the Amended Loan Agreement.
On April 28, 2023, the Company entered into the Amended Loan Agreement. The Amended Loan Agreement was treated as a modification.
In connection with the Amended Loan Agreement, the Company repaid $10.0 million of the principal balance outstanding, for which the
prepayment premium was waived. Pursuant to the Amended Loan Agreement, the interest rate on all borrowings under the Amended Loan
Agreement is the sum (the Basic Rate) of (a) the greater of 8.0% or The Wall Street Journal prime rate (the Prime Rate), plus (b) 2.0%, which
is paid-in-kind in the form of additional term loans (PIK Loans). Under the Amended Loan Agreement, an amount equal to 1.5% of the Basic
Rate will be payable in-kind and capitalized to the principal amount of the outstanding term loan on a monthly basis until April 1, 2026, after
which interest is scheduled to accrue at the Basic Rate. The maturity date of the loan was extended to December 31, 2026. The Company
estimated the effective interest rate of this loan to be approximately 11.0% and 8.5% as of December 31, 2023 and 2022, respectively.
Accrued interest is due and payable monthly, unless the Company elects to pay paid-in-kind interest. The outstanding principal and accrued
interest under the Amended Loan Agreement is to be repaid in ten equal monthly installments commencing in April 2026. Upon repayment of
the final installment under the Amended Loan Agreement, the Company is required to pay an additional fee of $1.0 million. This obligation is
being accreted into interest expense over the term of the loan using the effective interest method. For the years ended December 31, 2023
and 2022, the Company issued PIK Loans totaling $0.4 million and $0.6 million, respectively. At December 31, 2023, $18.2 million in principal
and PIK loans are outstanding, all of which is included in borrowings-non-current portion on the accompanying balance sheet.
The Amended Loan Agreement currently requires a prepayment premium of 1% of the aggregate outstanding principal for any prepayments
made prior to November 1, 2024.
The Amended Loan Agreement is collateralized by a first priority security interest in substantially all of the Company's assets, including
intellectual property. The affirmative covenants of the Amended Loan Agreement require that the Company timely file taxes, maintain good
standing and government compliance, maintain liability and other insurance, provide prompt notification of significant corporate events, and
furnish audited financial statements within 150 days of fiscal year end without qualification as to the scope of the audit or as to going concern
and without any other similar qualification.
The affirmative covenants require that the Company achieve a specified level of revenue, as measured quarterly on a rolling twelve-month
basis, however the Company is not required to comply with the revenue covenant for any quarter during which it maintains a minimum
aggregate cash balance equal to fifty percent of the aggregate principal amount of the Amended Loan Agreement (excluding any capitalized
interest paid-in-kind) at all times during such quarter. The consequences of failing to achieve the performance covenants, when applicable,
will be cured if, (i) within thirty days of failing to achieve the performance covenant, the Company submits a new Board approved financial
plan to Innovatus under which the Company is expected to break even on a cash flow basis prior to the maturity date, and (ii) within thirty
days of the submission of such financial plan, the Company issues additional equity securities or subordinated debt with net proceeds
sufficient to fund any cash flow deficiency generated from operations, as defined in the Amended Loan Agreement. The Amended Loan
Agreement requires that the Company maintain certain levels of minimum liquidity and maintains an unrestricted cash balance of $2.0
million.
The negative covenants provide, among other things, that without the prior consent of Innovatus, subject to certain exceptions, the Company
may not dispose of certain assets, engage in certain business combinations or acquisitions, incur additional indebtedness or encumber any
of the Company's property, pay dividends on the Company's capital stock or make prohibited investments. The Amended Loan Agreement
provides that an event of default will occur if, among other triggers, (i) the Company defaults in the payment of any amount payable under the
agreement when due, (ii) there occurs any circumstance(s) that could reasonably be expected to result in a material adverse effect on the
Company's business, operations or condition, or on the Company's ability to perform its obligations under the agreement, (iii) the Company
becomes insolvent, (iv) the Company undergoes a change in control or (v) the Company breaches any negative covenants or certain
affirmative covenants in the agreement or, subject to a cure period, otherwise neglects to perform or observe any material item in the
agreement.
At December 31, 2023, the Company was in compliance with all covenants of the Amended Loan Agreement.
F-15
Upon an event of default in any of the Amended Loan Agreement covenants, the repayment of the 2017 Term Loan may be accelerated, and
the applicable interest rate will be increased by 4.0% until the default is cured. Although repayment of the 2017 Term Loan can be
accelerated under certain circumstances, the Company believes acceleration of this loan is not probable as of the date of these financial
statements. Accordingly, the Company has reflected the amounts of the Third Loan Amendment due beyond twelve months of the balance
sheet date as non-current.
2022 Equipment Notes Payable
In May 2022, the Company purchased laboratory equipment using notes payable. At December 31, 2023, the total notes payable balance
related to this financed equipment was $0.8 million, with $0.3 million classified within borrowings-current portion and $0.5 million within
borrowings-non-current portion, net of discounts and debt issuance costs in the accompanying balance sheets. At December 31, 2022, the
total notes payable balance related to this financed equipment was $0.8 million, with $0.2 million classified within borrowings-current portion
and $0.6 million within borrowings-non-current portion, net of discounts and debt issuance costs in the accompanying balance sheets. The
financed equipment is subject to a 5.28% effective interest rate and will mature on October 1, 2026.

Operating Leases
The Company leases office and laboratory space located in Vista, California. The lease expires in April 2027, with an option to extend
portions of the lease for additional 5-year periods. The Company has not included the optional renewal periods in the measurement of the
lease liability, because it is not reasonably certain that the Company will exercise these renewal options. The Company's payments under the
lease are subject to escalation clauses.
The Company leases additional office space in Carlsbad, California, under a sub-lease which commenced in October 2021 and expires in
April 2027. Monthly base rent under the sub-lease agreement is $70,042. The monthly base rent increases by approximately 3% annually,
each October 1, through the remainder of the lease term.
Finance Leases
The Company has entered into various finance lease agreements to obtain laboratory equipment. The terms of the Company's finance
leases generally range from three to five years and are typically secured by the underlying equipment. The portion of the future payments
designated as principal repayments were classified as finance lease liabilities on the Company's balance sheet.

In connection with the acquisition of the medical diagnostics division of Royalty Pharma Collection Trust (Royalty Pharma) (formerly known
as Cypress Bioscience, Inc.) in 2010, the Company had royalty payment obligations of 2.5% on net sales of products which incorporate
certain acquired technologies through December 31, 2023. These obligations no longer exist for products sold after December 31, 2023.
Licensing Agreements
The Company has licensed technology for use in its diagnostic tests. In addition to the milestone payments required by these agreements,
individual license agreements generally provide for ongoing royalty payments ranging from 1.5% to 7.0% on net sales of products which
incorporate licensed technology, as defined in such agreements. Royalties are accrued when incurred and recorded in costs of revenue in
the accompanying statements of operations.
Supply Agreements
In December 2021, the Company amended a supply agreement with one supplier for reagents which includes minimum annual purchase
commitments of $8.0 million and $9.2 million for the years ended December 31, 2024 and 2025, respectively.
Collaboration Obligations
In May 2021, the Company entered into a master research collaboration agreement with Allegheny Health Network Research Institute (AHN),
pursuant to which the Company is required to pay AHN a collaboration fee of $0.4 million per year. Collaboration expenses under the master
research collaboration agreement were $0.3 million for each of the years ended December 31, 2023 and 2022. Collaboration expenses
under the AHN collaboration are included in research and development expenses in the accompanying statements of operations.
Contingencies
In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties
and provide for general indemnifications; including for subpoenas and other civil investigative demands, from governmental agencies,
Medicare or Medicaid and managed care organizations reviewing billing practices or requesting comment on allegations of billing
irregularities that are brought to their attention through billing audits or third parties. The Company's exposure under these agreements is
unknown because it involves claims that may be made against the Company in the future, but have not yet been made or that the Company
believes to be immaterial. The Company accrues a liability for such matters when it is probable that future expenditures will be made and
such expenditures can be reasonably estimated.
Litigation
From time to time, the Company may be subject to various legal proceedings that arise in the ordinary course of business activities. The
Company does not believe the outcome of any such matters as of December 31, 2023 will have a material effect on its financial position or
results of operations.
F-18
In October 2023, the Company resolved an investigation with the U.S. Attorney’s Office for the District of Massachusetts that was initiated by
a qui tam lawsuit. Pursuant to a Settlement Agreement, the Company made a single lump-sum remittance to the government in the amount
of $0.7 million in connection with specimen processing arrangements that Exagen historically had with physicians. The U.S. Attorney’s Office
dismissed this “covered conduct” in the qui tam lawsuit with prejudice, while non-covered conduct was dismissed without prejudice. In
November 2023 the complaint was unsealed and served on Exagen. Exagen filed a motion to dismiss the complaint. In December 2023, the
Company's insurance carrier provided reimbursement for certain defense costs the Company incurred in the October 2023 qui tam lawsuit. In
February 2024, the relator filed a motion for leave to amend the complaint. Exagen opposed this motion, and all motions are still pending.
The Company intends to vigorously defend against the claims being asserted in the complaint.
The Company's participation in federal healthcare programs is not affected by the Settlement Agreement.
Note 7. Fair Value Measurements
The carrying values of the Company's cash, cash equivalents and restricted cash, accounts receivable, prepaid expenses and other current
assets, accounts payable and accrued and other current liabilities approximate their fair values due to their short-term nature and are
considered to be Level 1 measurements. The estimated fair value of the Company's long-term borrowings is determined by Level 2 inputs
and based primarily on quoted market prices for the same or similar issues. As of December 31, 2023, the Amended Loan Agreement had a
carrying value of $18.7 million and a fair value of $19.7 million. As of December 31, 2022, the 2017 Term Loan had a carrying value of
$28.3 million and a fair value of $26.9 million. The estimated fair value of the Amended Loan Agreement was determined based on a
discounted cash flow approach using available market information on discount and borrowing rates with similar terms, maturities, and credit
ratings. The carrying value of the Company's other long-term borrowing as of December 31, 2023 was $0.8 million, which approximated its
fair value.
Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or
most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
Techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.
The three-levels of the valuation hierarchy for disclosure of fair value measurements are defined as follows:
Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities;
Level 2 - Inputs other than quoted prices included within Level I that are observable, unadjusted quoted prices in markets that are not
active, or other inputs that are observable or can be corroborated by observable market data for substantially the full
term of the related assets or liabilities; and
Level 3 - Unobservable inputs that are supported by little or no market activity for the related assets or liabilities.
The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair
value measurement.
The following table sets forth the Company's financial instruments that were measured at fair value on a recurring basis within the fair value
hierarchy (in thousands):

Note 9. Stock Option Plan
2019 Incentive Award Plan
In September 2019, the Company's board of directors adopted, and the Company's stockholders approved, the 2019 Plan. Under the 2019
Plan, which expires in September 2029, the Company may grant stock options, stock appreciation rights, restricted stock, RSUs and other
awards to individuals who are then employees, officers, non-employee directors or consultants of the Company or its subsidiaries. The
options generally expire ten years after the date of grant and are exercisable to the extent vested. Vesting is established by the Company's
board of directors and is generally four years from the date of grant or, for grants to new hires, date of hire. The 2019 Plan contains an
"evergreen provision" that allows annual increases in the number of shares available for issuance on the first day of each calendar year
through January 1, 2029 in an amount equal to the lesser of: (i) 4% of the outstanding capital stock on each December 31st, or (ii) such
lesser amount determined by the Company's board of directors. As of December 31, 2023, 1,831,107 shares of common stock remained
available for future awards.
F-20
Pursuant to the evergreen provision, on January 1, 2024, an additional 681,838 shares of common stock became available for issuance
under the 2019 Plan.

The weighted-average grant date fair value per share of options granted during the years ended December 31, 2023 and 2022 was $2.17
and $2.74, respectively. The aggregate intrinsic value of options exercised during the years ended December 31, 2023 and 2022 was $0.2
million and $0.6 million, respectively. The intrinsic value is calculated as the difference between the fair value of the Company's common
stock and the exercise price of the stock options. The fair value of the Company's common stock was $1.99 and $2.40 per share at
December 31, 2023 and 2022, respectively. As of December 31, 2023, total unrecognized compensation cost related to option awards was
$0.3 million, which is expected to be recognized over a remaining weighted-average vesting period of 0.8 years.
2019 Employee Stock Purchase Plan
In September 2019, the Company's board of directors adopted, and the Company's stockholders approved, the ESPP. The ESPP became
effective on the day the ESPP was adopted by the Company's board of directors. The ESPP permits participants to purchase common stock
through payroll deductions of up to 20% of their eligible compensation. The number of shares of common stock available for issuance under
the ESPP will be annually increased on the first day of each calendar year during the term of the ESPP through January 1, 2029 in an
amount equal to the lesser of (i) 1% of the outstanding capital stock on each December 31st, or (ii) such lesser amount determined by the
Company's board of directors. During the year ended December 31, 2023, the Company issued 129,593 shares of common stock pursuant
to scheduled purchases under the ESPP. As of December 31, 2023, 449,332 shares of common stock remained available for issuance.
Pursuant to the evergreen provision, on January 1, 2024, an additional 170,460 shares became available for issuance under the ESPP.
F-21
Stock-based compensation expense related to the ESPP for each of the years ended December 31, 2023 and 2022 was less than $0.1

Significant components of the Company’s deferred tax assets at December 31, 2023 and 2022 are shown below (in thousands). A valuation
allowance has been established as realization of the Company’s deferred tax assets has not met the more likely-than-not threshold
requirement. If the Company’s judgment changes and it is determined that the Company will be able to realize these deferred tax assets, the
tax benefits relating to any reversal of the valuation allowance on deferred tax assets will be accounted for as a reduction to income tax
expense.
Deferred tax assets:

At December 31, 2023 and 2022, the Company had federal NOL carryforwards of approximately $129.8 million and $118.4 million,
respectively. At December 31, 2023 and 2022, the Company had state NOL carryforwards of $91.0 million and $87.0 million, respectively.
Approximately $43.5 million of the federal tax loss carryforwards will begin to expire in 2024, unless previously utilized. The federal NOL
carryforwards generated after December 31, 2017 of $86.3 million will carryforward indefinitely. The Company’s state tax loss carryforwards
will begin to expire in 2030, unless previously utilized.
At December 31, 2023, the Company's deferred tax assets are primarily comprised of federal and state tax NOL carryforwards. The
Company completed a formal study through the year ended December 31, 2019 and determined ownership changes within the meaning of
Internal Revenue Code (IRC), Section 382 had occurred in 2003, 2008, 2012, 2017 and 2019. Based on the analysis, $61.1 million of the
Company's tax attribute carryforwards through December 31, 2017 cannot be utilized under IRC Section 382. The Company's ability to utilize
NOL carryforwards generated after December 31, 2017 will not expire under the Tax Cuts and Jobs Act of 2017. The Company adjusted tax
attribute carry forwards and deferred tax assets accordingly. As the deferred tax assets associated with the tax attribute carry forwards were
fully offset by a valuation allowance, a corresponding reduction in the Company's valuation allowance was also recorded, resulting in no
income tax impact.
The Company is subject to taxation in the U.S. and in various state jurisdictions. The Company’s tax years for 2004 and forward are subject
to examination by the U.S. and state tax authorities due to the carryforward of unutilized net operating losses and research and development
credits.
The Company recognizes interest and/or penalties related to income tax matters in its provision for income taxes. The Company does not
have any material accruals for, and did not recognize any, material interest or penalties in these financial statements in any period presented.
Uncertain Tax Positions
At December 31, 2023 and 2022, the Company had no unrecognized tax benefits.
The Company does not believe that the balance of unrecognized tax benefits will materially change within the next twelve months.
Note 11. 401(k) Plan
The Company sponsors an employee savings plan that qualifies as a deferred salary arrangement under Section 401(k) of the Code.
Participating employees may defer up to the Internal Revenue Service annual contribution limit. Additionally, the Company may elect to make
contributions into the savings plan at its sole discretion. For each of the years ended December 31, 2023 and 2022, the Company made
contributions to the 401(k) Plan at 4% of qualified employee compensation. For the years ended December 31, 2023 and 2022, these
contributions totaled approximately $0.8 million and $0.9 million, respectively.

Exhibit 4.8
DESCRIPTION OF SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF
THE SECURITIES EXCHANGE ACT OF 1934
General
The following description summarizes some of the terms of our capital stock. Because it is only a summary, it does not contain all the
information that may be important to you and is subject to and qualified in its entirety by reference to our amended and restated certificate of
incorporation (the Certificate of Incorporation) and amended and restated bylaws (the Bylaws) which are filed as exhibits to our Annual
Report on Form 10-K and are incorporated by reference herein. We encourage you to read our Certificate of Incorporation and our Bylaws for
additional information.
Our authorized capital stock consists of 200,000,000 shares of common stock, $0.001 par value per share, and 10,000,000 shares of
preferred stock, $0.001 par value per share.
Common Stock
Voting Rights
Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders, including
the election of directors, and do not have cumulative voting rights. Accordingly, the holders of a majority of the outstanding shares of common
stock entitled to vote in any election of directors can elect all of the directors standing for election, if they so choose, other than any directors
that holders of any preferred stock we may issue may be entitled to elect. Subject to the supermajority votes for some matters, other matters
shall be decided by the affirmative vote of our stockholders having a majority in voting power of the votes cast by the stockholders present or
represented and voting on such matter. Our Certificate of Incorporation and Bylaws also provide that our directors may be removed only for
cause and only by the affirmative vote of the holders of at least two-thirds in voting power of the outstanding shares of capital stock entitled to
vote thereon. In addition, the affirmative vote of the holders of at least two-thirds in voting power of the outstanding shares of capital stock
entitled to vote thereon is required to amend or repeal, or to adopt any provision inconsistent with, several of the provisions of our Certificate
of Incorporation.
Dividends
Subject to preferences that may be applicable to any then outstanding preferred stock, holders of common stock are entitled to
receive ratably those dividends, if any, as may be declared by the board of directors out of legally available funds.
Liquidation Rights
In the event of our liquidation, dissolution or winding up, the holders of common stock will be entitled to share ratably in the assets legally
available for distribution to stockholders after the payment of or provision for all of our debts and other liabilities, subject to the prior rights of
any preferred stock then outstanding. Holders of common stock have no preemptive or conversion rights or other subscription rights and
there are no redemption or sinking funds provisions applicable to the common stock. All outstanding shares of common stock are, and the
common stock to be outstanding upon the closing of this offering will be, duly authorized, validly issued, fully paid and nonassessable. The
rights, preferences and privileges of holders of common stock are subject to and may be adversely affected by the rights of the holders of
shares of any series of preferred stock that we may designate and issue in the future.
Preferred Stock
Under the terms of our Certificate of Incorporation, our board of directors has the authority, without further action by our stockholders, to
issue up to 10,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in
each such series, to fix the dividend, voting and other rights, preferences and privileges of the shares of each wholly unissued series and any
qualifications, limitations or restrictions thereon, and to increase or decrease the number of shares of any such series, but not below the
number of shares of such series then outstanding.
Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the
voting power or other rights of the holders of the common stock. The issuance of preferred stock, while providing flexibility in connection with
possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change
in our control and may adversely affect the market price of the common stock and the voting and
other rights of the holders of common stock. We have no current plans to issue any shares of preferred stock.
Prior to the issuance of shares of each series, the board of directors is required by the General Corporation Law of the State of Delaware
(the DGCL) and our Certificate of Incorporation to adopt resolutions and file a certificate of designation with the Secretary of State of the
State of Delaware. The certificate of designation fixes for each class or series the designations, powers, preferences, rights, qualifications,
limitations and restrictions, including dividend rights, conversion rights, redemption privileges and liquidation preferences.
Anti-Takeover Effects of Delaware Law and Our Certificate of Incorporation and Bylaws
Some provisions of Delaware law, our Certificate of Incorporation and our Bylaws contain provisions that could make the following
transactions more difficult: an acquisition of us by means of a tender offer; an acquisition of us by means of a proxy contest or otherwise; or
the removal of our incumbent officers and directors. It is possible that these provisions could make it more difficult to accomplish or could
deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions which
provide for payment of a premium over the market price for our shares.
These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These
provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe
that the benefits of the increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to
acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in
an improvement of their terms.
Undesignated Preferred Stock
The ability of our board of directors, without action by the stockholders, to issue up to 10,000,000 shares of undesignated preferred stock
with voting or other rights or preferences as designated by our board of directors could impede the success of any attempt to change control
of us. These and other provisions may have the effect of deferring hostile takeovers or delaying changes in control or management of our
company.
Stockholder Meetings
Our Bylaws provide that a special meeting of stockholders may be called only by our chairman of the board, chief executive officer or
president (in the absence of a chief executive officer), or by a resolution adopted by a majority of our board of directors.
Requirements for Advance Notification of Stockholder Nominations and Proposals
Our Bylaws establish advance notice procedures with respect to stockholder proposals to be brought before a stockholder meeting and
the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a
committee of the board of directors.
Elimination of Stockholder Action by Written Consent
Our Certificate of Incorporation and Bylaws eliminate the right of stockholders to act by written consent without a meeting.
Staggered Board
Our board of directors is divided into three classes: Class I, Class II and Class III. The directors in each class will serve for a three-year
term, one class being elected each year by our stockholders. This system of electing and removing directors may tend to discourage a third
party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders
to replace a majority of the directors.
Removal of Directors
Our Certificate of Incorporation provides that no member of our board of directors may be removed from office by our stockholders
except for cause and, in addition to any other vote required by law, upon the approval of not less than two thirds of the total voting power of
all of our outstanding voting stock then entitled to vote in the election of directors.
Stockholders Not Entitled to Cumulative Voting
Our Certificate of Incorporation does not permit stockholders to cumulate their votes in the election of directors. Accordingly, the holders
of a majority of the outstanding shares of our common stock entitled to vote in any election of directors can elect all of the directors standing
for election, if they choose, other than any directors that holders of our preferred stock may be entitled to elect.

Delaware Anti-Takeover Statute
We are subject to Section 203 of the Delaware General Corporation Law, which prohibits persons deemed to be “interested
stockholders” from engaging in a “business combination” with a publicly held Delaware corporation for three years following the date these
persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested
stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested stockholder” is a
person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did
own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or stock sale, or other
transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with
respect to transactions not approved in advance by the board of directors.
Choice of Forum
Our Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative form, the Court of Chancery
of the State of Delaware will be the sole and exclusive forum for: (i) any derivative action or proceeding brought on our behalf; (ii) any action
asserting a claim of breach of a fiduciary duty or other wrongdoing by any of our directors, officers, employees or agents to us or our
stockholders, creditors or other constituents; (iii) any action asserting a claim against us arising pursuant to any provision of the General
Corporation Law of the State of Delaware or our Certificate of Incorporation or Bylaws; (iv) any action to interpret, apply, enforce or determine
the validity of our Certificate of Incorporation or Bylaws; or (v) any action asserting a claim governed by the internal affairs doctrine. This
exclusive forum provision would not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or
any other claim for which the federal courts have exclusive jurisdiction. Our Bylaws provide that, unless we consent in writing to the selection
of an alternative forum, the federal district courts of the United States of America shall be the sole and exclusive forum for the resolution of
any complaint asserting a cause of action arising under the Securities Act. To the extent that any such claims may be based upon federal law
claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by
the Exchange Act or the rules and regulations thereunder. The enforceability of similar choice of forum provisions in other companies’
certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be
inapplicable or unenforceable. Our Certificate of Incorporation and Bylaws also provide that any person or entity purchasing or otherwise
acquiring any interest in shares of our capital stock will be deemed to have notice of and to have consented to this choice of forum provision.
Amendment of Charter Provisions
The amendment of any of the above provisions, except for the provision making it possible for our board of directors to issue preferred
stock, would require approval by holders of at least two thirds of the total voting power of all of our outstanding voting stock.
The provisions of Delaware law, our Certificate of Incorporation and our Bylaws could have the effect of discouraging others from
attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock
that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in the
composition of our board and management. It is possible that these provisions could make it more difficult to accomplish transactions that
stockholders may otherwise deem to be in their best interests.
Transfer Agent and Registrar
The transfer agent and registrar for our common stock is Computershare Trust Company, N.A. The transfer agent and registrar’s address
is 6200 S. Quebec St., Greenwood Village, CO 80111.
Stock Exchange Listing
Our common stock is listed for trading on Nasdaq under the symbol “XGN.”
