PART I 

ITEM 1.  BUSINESS 

Overview  

We are a leading innovator in treatments for atrial fibrillation (Afib) and left atrial appendage (LAA) management. According to 

the American Heart Association, Afib affects 1-2% of the population in the United States. It is the most common cardiac arrhythmia, 
or irregular heartbeat, encountered in clinical practice and results in high utilization of healthcare services by Afib patients. Symptoms 
of Afib may include heart palpitations, dizziness, fatigue and shortness of breath, and these symptoms may be debilitating and life 
threatening in some cases. When a patient is in Afib, abnormal electrical impulses cause the atria, or upper chambers of the heart, to 
fibrillate, or beat rapidly, irregularly, and in an uncoordinated fashion. As a result, blood in the atria may be in stasis, increasing the 
risk that a blood clot will form and cause a stroke or other serious complications. In patients with Afib, a significant percentage of 
those clots can form inside of the LAA. Patients often progress from being in Afib intermittently (paroxysmal) to being in Afib 
continuously. The continuous Afib patient population includes persistent Afib, which lasts seven days to one year, and long-standing 
persistent Afib, which lasts longer than one year. Afib often occurs in conjunction with other cardiovascular diseases, including 
hypertension, congestive heart failure, left ventricular dysfunction, coronary artery disease and valvular disease. 

Our ablation and left atrial appendage management (LAAM) products are used by physicians during both open-heart and 
minimally invasive procedures. In open-heart procedures, the physician is performing heart surgery for other conditions and our 
products are used in conjunction with (“concomitant” to) such a procedure. Minimally invasive procedures are performed on a 
standalone basis, and often include multi-disciplinary or “hybrid” approaches, combining both surgical procedures using AtriCure 
ablation and LAAM products and catheter ablation.  

We believe that we are currently the market leader in the surgical treatment of Afib. Our Isolator® Synergy™ Ablation System 

is approved by the United States Food and Drug Administration (FDA) for the treatment of persistent and long-standing persistent 
Afib concomitant to other open-heart surgical procedures. All of our other ablation devices are cleared for sale in the United States 
under FDA 510(k) clearances, including our other radio frequency (RF) and cryoablation products, which are indicated for the 
ablation of cardiac tissue and/or the treatment of cardiac arrhythmias. In addition, certain of our cryoablation probes are cleared for 
managing pain by temporarily ablating peripheral nerves, or cryo nerve block therapy. In January 2021, we announced 510(k) 
clearance of additional labeling claims for cryo nerve block therapy to include the treatment of adolescent patients (12-21 years of 
age). Our AtriClip® LAA Exclusion System products are 510(k)-cleared with an indication for the exclusion of the LAA, performed 
under direct visualization and in conjunction with other cardiac surgical procedures. Direct visualization, in this context, requires that 
the surgeon is able to see the heart directly, with or without assistance from a camera, endoscope or other appropriate viewing 
technologies. The LARIAT® system is cleared for soft tissue ligation. Several of our products are currently being studied to expand 
labeling claims or to support indications specifically for the treatment of Afib. Our Isolator Synergy clamps, Isolator Synergy pens, 
Coolrail® linear pen, cryoablation devices, certain products of the AtriClip LAA Exclusion System, COBRA Fusion® Ablation 
System, the EPi-Sense® Guided Coagulation System with VisiTrax® technology, and LARIAT Suture Delivery Device bear the CE 
mark and may be commercially distributed throughout the member states of the European Union and other countries that comply with 
or mirror the Medical Device Directive. Our Isolator Synergy clamps, Isolator Synergy pens, Coolrail linear pen, cryoablation devices, 
and certain products of the AtriClip LAA Exclusion System are available in select Asia-Pacific countries. We anticipate that 
substantially all of our revenue for the foreseeable future will relate to products we currently sell or are in the process of developing. 

We sell our products to medical centers through our direct sales force in the United States and in certain international markets, 
such as Germany, France, the United Kingdom and the Benelux region. We also sell our products to distributors who in turn sell our 
products to medical centers in other international markets. Our business is primarily transacted in U.S. Dollars with the exception of 
transactions with our European customers, which are transacted primarily in the Euro or the British Pound. 

Market Overview  

Afib is the most commonly diagnosed sustained cardiac arrhythmia with approximately 1.2 million diagnoses annually in the 
United States, and affects approximately 33 million people worldwide. It is estimated that the incidence of Afib doubles with each 
decade of an adult’s life. At age 40, remaining lifetime risk for Afib is 26% for men and 23% for women. Afib is an under-diagnosed 
condition due in large part to the fact that patients with Afib often have mild or no symptoms, and their Afib is often only diagnosed 
when they seek treatment for an associated condition, such as a structural heart disease or stroke. We believe that increasing awareness 
of Afib and improved diagnostic screening will result in an increased number of patients diagnosed with Afib over time. Also, since 
the prevalence of Afib increases with age, there will likely be an increase in the number of diagnosed Afib patients in the United 
States as the population ages. We believe that the same trends in the United States apply globally.  

2 

  
 
 
Afib is a condition that doctors often find difficult to treat and, historically, there has been no widely accepted long-term cure 

for Afib. This difficulty is exacerbated with more serious forms of Afib, or persistent and long-standing persistent Afib. Over the past 
two decades, technology advancements have made surgical ablation more effective, repeatable and available to cardiac surgeons and 
electrophysiologists around the world. Societal guideline changes from the Society of Thoracic Surgeons (STS), Heart Rhythm 
Society (HRS), and American Association of Thoracic Surgery (AATS) have Class I recommendations for surgical ablation, meaning 
that it is a “recommended” treatment, no longer just “reasonable”, for patients who have structural heart disease and Afib. In addition, 
guidelines for the treatment of more serious forms of Afib have also been introduced in the past several years. These societal 
guidelines are reflective of the scientific evidence suggesting that surgical ablation is safe and effective for patients who have Afib.  

Of the patients undergoing open-heart surgery globally on an annual basis, we estimate that over 250,000 are potential 

candidates for surgical ablation using our products. Today, we estimate that approximately 25% to 35% of those candidates are being 
treated, but we believe many are not treated properly or fully. Of the population diagnosed with Afib, a large percentage of patients 
are symptomatic and do not respond to pharmacological therapy. Additionally, there is a large population of patients who have no 
other underlying cardiac disease but who suffer from serious forms of Afib. Many of these patients fail traditional therapies, and thus 
we believe could benefit from a minimally invasive or hybrid Afib treatment using our products. 

In addition, Afib is thought to be responsible for approximately 15% to 20% of the estimated 800,000 strokes that occur 
annually in the United States. According to the American Heart Association, the risk of stroke is five times higher in people with Afib. 
Studies have also suggested that 90% of clots that cause strokes in patients who have Afib originate from within the LAA. Afib 
accounts for billions of dollars in hospitalization-related and office visit costs in the United States each year. Indirect costs, such as the 
management of Afib-related strokes, are believed to be significant. Because of the risk of stroke and the significant cost burden on the 
healthcare system, more and more surgeons are routinely addressing the LAA, both in patients who have Afib, but also in those who 
do not have Afib but may be at increased risk of developing the disease in the future. We believe that our AtriClip system is safer, 
more effective and easier to use than other products and techniques for excluding the LAA during cardiac surgery. Therefore, we 
believe that the market for the AtriClip system represents a significant growth opportunity. 

Cardiothoracic and thoracic surgery involving an incision through the ribcage, typically referred to as thoracotomy access, can 

often times result in post-operative pain and longer hospital recovery times as patients refrain from mobilizing their chest near the 
incision site. Most surgeons will employ a multi-modal pain management protocol that includes global and local pain management 
techniques, including epidural delivery of medication directly around the spinal cord, intravenous, or oral delivery of opioid and non-
opioid pain medications. More focused, local techniques include syringe injections between vertebrates and cryo nerve block, the use 
of cryo-energy to temporarily ablate peripheral nerves. Cryo nerve block can be delivered using our cryoICE cryoSPHERE® probe, 
which is specifically designed for cryo nerve block, as well as our cryoICE CRYO2 probe, one of the same probes used to treat 
cardiac arrhythmias. Depending on the degree of invasiveness, physicians and their nursing staff will take advantage of multiple 
modes of pain management.  It is estimated that each year roughly 140,000 cardiac and thoracic procedures are performed in the 
United States through thoracotomy access. Hospital recovery times can vary from two to eight days depending on the procedure, 
operative complications associated with the procedure, pain management protocol, and other factors. In recent years, opioids have 
come under heavy scrutiny due to their potential for long-term dependency, overdose and possible death. The Center for Disease 
Control has reported over 49,000 deaths involving opioids in the United States in a single year, and both federal and local 
governments in the United States have proposed and implemented new regulations to curb the opioid overdose epidemic. It is also 
estimated that one in seven cardiothoracic surgical patients develops an unhealthy post-procedural addiction to prescription narcotics, 
making alternative, non-opioid pain management modalities, such as cryo nerve block, increasingly important.  

The AtriCure Solution and Products  

Our products enable cardiothoracic surgeons to mimic all or portions of the cut and sew Maze procedure with faster, less 
invasive and less technically challenging approaches. We have completed, and continue to invest in, clinical studies for the use of our 
ablation and left atrial appendage management products to treat Afib. Leading cardiothoracic surgeons and electrophysiologists, 
including those who serve or who have served as consultants to us, have published results of pre-clinical and clinical studies utilizing 
our devices. The results of these studies have assessed efficacy, ease of use and safety endpoints.

Products for cardiac tissue ablation include those that heat tissue using radio frequency (RF) energy to create the tissue effects or 

those that cool tissue using cryo-thermal heat transfer to create the tissue effects. Our ablation products are part of platforms each 
consisting of disposable handpieces which connect to compact RF power generation sources or the cryoICE Box generator that we 
generally place with our direct customers and sell to our distributors. 

Products for open and minimally invasive ablation: 

• 

Isolator Synergy Clamps. Our Isolator Synergy System historically represented our primary product line and 
currently generates the majority of our ablation-related revenue. All of our clamps are single-use disposable RF 
products with jaws that close in a parallel fashion. We sell multiple configurations of our Isolator Synergy clamps 
with the primary difference being the form of the clamping jaws. The parallel closure compresses tissue and 
evacuates the blood and fluids from the energy pathway in order to make the ablation more effective. The Isolator 
Synergy System is currently being evaluated under the DEEP AF IDE pivotal trial and was previously studied under 
the ABLATE clinical trial supporting a pre-market approval (PMA) in 2011. 

•  Multifunctional Pens and Linear Ablation Devices. These devices are single-use disposable RF products that 
come in multiple configurations which have different contact lengths. The MAX Pen devices enable surgeons to 
evaluate cardiac arrhythmias, perform temporary cardiac pacing, sensing and stimulation and ablate cardiac tissue 
with the same device. Surgeons are able to readily toggle back and forth between these functions. The Coolrail 
device enables the user to make longer linear lines of ablation. Surgeons generally use one or more of our pen and 
linear devices in combination with Isolator Synergy clamps.  

Products for open ablation: 

• 

cryoICE Cryoablation System. The cryoICE cryoablation system is used in open ablation procedures and consists 
of the cryoICE Box generator along with a single-use disposable probe. The primary differences between these 
cryoablation probes is the form of the distal end. The cryoICE devices enables the user to make linear ablations of 
varied lengths. Surgeons may utilize the cryoICE devices in combination with Isolator Synergy clamps or 
independently. The ICE-AFIB clinical trial is studying the safety and efficacy of the cryoICE system for persistent 
and long-standing persistent Afib treatment during concomitant on-pump cardiac surgery. The cryoSPHERE system 
and certain cryoICE devices are used to apply cryo-energy to targeted intercostal peripheral nerves in the ribcage in 
order to provide temporary pain relief. This technique, called cryo nerve block, is applied intra-operatively by 
cardiothoracic or thoracic surgeons and results in temporary pain relief for up to 90 days after the procedure. 
Sensation typically returns to the affected region of the chest after this period. Studies, including the FROST trial, 
are ongoing to characterize the effects of cryo nerve block and further refine the procedure.  

Products for minimally invasive ablation: 

• 

EPi-Sense Guided Coagulation System with VisiTrax Technology. The EPi-Sense Guided Coagulation System 
with VisiTrax technology utilizes monopolar RF energy for the coagulation of tissue. The Epi-Sense device is a 
single-use disposable which is also capable of intra-operative cardiac signal sensing and recording when connected 
to an external recording device. The CONVERGE IDE clinical trial evaluated the safety and efficacy of the EPi-
Sense Guided Coagulation System with VisiTrax technology to treat symptomatic persistent and long-standing 
persistent Afib patients who are refractory or intolerant to at least one Class I and/or III anti-arrhythmic drug. The 
results from the trial have been submitted to the FDA as part of a PMA submission.  

Products for appendage management: 

• 

• 

AtriClip System. The AtriClip System includes an implantable device (AtriClip) coupled to a single-use disposable 
applier. The AtriClip is designed to exclude the left atrial appendage by mechanically clamping the appendage from 
the outside of the heart, eliminating blood flow between the left atrial appendage and the atrium while avoiding 
contact with circulating blood. We believe that the AtriClip system is potentially safer, more effective and easier to 
use than other available products and techniques for permanently excluding the left atrial appendage. These benefits 
compared to other techniques include permanent exclusion and electrical isolation of the appendage. The AtriClip 
device comes in a variety of lengths allowing the user to select a configuration specific to the patient and in two 
geometries (a rectangular configuration which encircles the targeted tissue and “V” shape which allows lateral 
access for improved usability). The appliers come in multiple forms tailored to specific procedural needs and with 
different deployment mechanisms. The AtriClip System includes various combinations of AtriClips and appliers. 

LARIAT System. The LARIAT System is a suture-based solution for soft-tissue closure and is compatible with a 
wide range of anatomical shapes. The product is currently being studied in the aMAZE IDE clinical trial. The Lariat 
System includes a suture loop coupled to a single-use disposable applier. The loop is designed to exclude the left 
atrial appendage by mechanically cinching the appendage from the outside of the heart, eliminating blood flow 
between the left atrial appendage and the atrium while avoiding contact with circulating blood.  The objective of the 
aMAZE IDE clinical trial is to demonstrate that using the LARIAT System for left atrial appendage exclusion, plus 

4 

  
 
a pulmonary vein isolation (PVI) catheter ablation, will lead to a reduced incidence of recurrent Afib compared to 
PVI alone, with a favorable safety profile. 

In addition to the above product lines we also sell enabling technologies including our Lumitip™ dissectors, COBRA Fusion 

Surgical Ablation System, the Fusion Magnetic Retriever System and a line of reusable cardiac surgery (valve) instruments. The 
Lumitip dissector is used by surgeons to separate tissues to provide access to key anatomical structures that are targeted for ablation. 
Cardiac surgery instruments are used during certain surgical procedures for repair or replacement of heart valves. 

Current Afib Treatment Alternatives 

Physicians usually begin treating Afib patients with a variety of drugs intended to prevent blood clots, control heart rate or 

restore the heart to normal sinus rhythm. If a patient’s Afib cannot be adequately controlled with drug therapy, doctors may perform 
one of several open-heart or minimally-invasive procedures that vary depending on the severity of the Afib symptoms and whether or 
not the patient suffers from other forms of heart disease. Often, Afib procedures are performed concomitantly with other cardiac 
treatments.  

Alternative treatments to open-heart and minimally invasive procedures include: 

• 

• 

• 

Drug Therapy. Pharmaceutical options called anti-arrhythmics are available to treat Afib. Depending on a patient’s 
severity of the disease and heart condition, physicians typically administer these medications in a hospital setting 
with continuous monitoring. If the patient goes back into a normal rhythm, the physician will often prescribe a 
similar anti-arrhythmic drug to try to prevent a recurrence of Afib. The effectiveness of drug therapy varies based 
on the patient population and the drug being prescribed, among other factors. Often, pharmaceuticals to thin the 
blood (anti-coagulants) are prescribed due to the increased risk of stroke for patients who also have Afib. 

Implantable Devices. Implantable devices, such as defibrillators and pacemakers, can be effective in reducing the 
symptoms of Afib episodes, but neither device is intended to treat Afib. Patients may continue to experience the 
adverse effects of Afib as well as some of the symptoms and complications, including dizziness, fatigue, 
palpitations and stroke because the Afib continues. 

Catheter Ablation. Catheter ablation is a procedure that is typically performed by an electrophysiologist. The 
ablations are made from the inside of the heart using a flexible catheter. The heart is reached via a blood vessel, 
most commonly through the femoral vein. In proportion to the prevalence of Afib, less than 6% of patients receive 
catheter-based Afib treatments each year in the United States. The rate of treatment is even lower for long-standing 
persistent patients in which less than 1% receive catheter-based Afib treatments. 

We do not promote our products specifically for Afib treatment in the United States, except for the Isolator Synergy System, 

which may be promoted according to its FDA-approved indication for patients with persistent and long-standing persistent Afib 
undergoing certain open concomitant procedures. During elective open-heart surgical procedures, such as bypass or valve surgery, 
cardiothoracic surgeons use our ablation systems to treat patients with a pre-existing history of Afib. Surgeons use our products to 
perform cardiac procedures that may vary depending on the length of time a patient has been diagnosed with Afib and whether the 
patient’s Afib is intermittent (paroxysmal), or continuous (non-paroxysmal), which is typically further classified as persistent or long-
standing persistent. Patients who have been diagnosed with Afib for a longer duration and have persistent or long-standing persistent 
forms of Afib generally receive more extensive ablation procedures than patients who have been diagnosed with Afib for a shorter 
duration or who have paroxysmal Afib. Additionally, during an open-heart procedure, physicians may use our AtriClip system to 
exclude the LAA.  

For those patients with Afib who do not require a concomitant open-heart surgical procedure, surgeons have used our products 
for minimally invasive Afib treatment procedures. These procedures have generally been performed through small incisions without 
the need to place patients on a heart-lung bypass machine. We do not currently have any products with FDA-approved indications for 
the standalone treatment of Afib, but we have two IDE trials underway at various stages of completion. Additionally, during a 
minimally invasive surgical procedure, physicians may use our AtriClip system to exclude the LAA. 

Certain physicians are combining various minimally invasive stand-alone epicardial ablation procedures (surgical ablation on 

the outside of the heart) with endocardial ablation and mapping techniques (catheter ablation from the inside of the heart). The 
combination of procedures are often referred to as “hybrid” or “multi-disciplinary” approaches, in that both surgical ablation and 
catheter ablations are performed. Sometimes, both procedures are performed on the same day or in the same hospital stay, where other 
times they are performed weeks or months apart. Patient health condition, physician preference, hospital logistics and procedural room 
availability influence the decision whether to perform hybrid ablations in a single or a staged setting. Physicians are reporting that they 
are performing these procedures utilizing certain of our products to primarily treat patients who have non-paroxysmal forms of Afib. 

Business Strategy  

We are passionately focused on reducing the global Afib epidemic and healing the lives of those affected. Our strategy is 
to expand the treatment options for patients who suffer from Afib or have a high risk of stroke through the continued development of 
5 

  
 
our technologies and expansion of our product offerings, global commercial expansion and clinical science investments. The key 
elements of our strategy include:  

New Product Innovation. Our product development pipeline includes projects which extend and improve our existing products, 

as well as research and development projects for new technologies. We plan to continue to develop new and innovative products, 
including those that allow us to enter new market opportunities or expand our growth in existing markets.  

Invest in Clinical Science. We continue to invest in landmark clinical trials, including the CONVERGE, aMAZE IDE and ICE-
AFIB IDE trials, to validate the long-term results of procedures using our products and to support applications to regulatory agencies 
for expanded indications. We also make clinical research grants to support our product development efforts and expand the body of 
clinical evidence. 

Build Physician and Societal Relationships. We have formed consulting relationships with cardiothoracic surgeons, 
cardiologists, electrophysiologists and thoracic surgeons who work with us to develop and evaluate our products. Additionally, we 
have formed advisory boards made up of key opinion leaders in multiple specialties to oversee our training and clinical programs. We 
are building these relationships to provide insight regarding treatment trends, input on future product direction and education for 
providers involved in treating the disease.  

We are partnering with leading surgical and cardiology societies to increase the awareness of Afib treatment options. In the past 

three years, both the Society for Thoracic Surgeons and the Heart Rhythm Society have released new guidelines on the surgical 
treatment of Afib in both open-heart and minimally-invasive settings.  

Provide Training and Education. We have recruited and trained sales and physician education professionals to effectively 
communicate to our customers the unique features and benefits of our technologies as they relate to their indications for use. Our 
highly trained professionals meet with physicians at institutions around the world to provide education and technical training on the 
features, benefits and safe-and-effective use of our products. With the approval of our Isolator Synergy System, we instituted a 
program to train providers on the use of the Isolator Synergy System to treat persistent and long-standing persistent Afib in patients 
undergoing open-heart surgery. We believe this training and education program has increased awareness about the surgical treatment 
of Afib during open-heart procedures, and we will continue to make investments to serve our physician customers. As a result of the 
educational process, we believe that awareness of our technologies is growing and will result in the increased use of our products.  

Expand Adoption of Our Minimally Invasive Products. We believe that the catalysts for expanded adoption of our minimally 

invasive products include completing clinical trials, including the CONVERGE, aMAZE IDE and DEEP AF IDE clinical trials, 
procedural advancements, such as the hybrid or multi-disciplinary procedure, continued innovation and product development, and the 
publication of additional scientific evidence supporting the safety and efficacy of hybrid treatments for persistent and long-standing 
persistent Afib. We believe these efforts will help validate the successful, long-term use of our products for patients with persistent 
and long-standing persistent Afib. We believe that ongoing research activities, including prospective clinical trials, new procedural 
techniques and anticipated presentations and publications will create an increased demand for our minimally invasive products.  

Evaluate Acquisition Opportunities. We expect to continue to be opportunistic with respect to acquisitions. We evaluate 
acquisition opportunities on a variety of factors, including investment in clinical science, product innovation and strategic and 
financial considerations. 

Clinical Trials  

In the United States, a significant risk device requires the prior submission of an application for an Investigational Device 

Exemption (IDE) to FDA for approval before initiating a clinical trial. Clinical trials are required to support a pre-market approval 
(PMA) and are sometimes required for 510(k) clearance. Some trials require a feasibility study followed by a pivotal trial. We are 
conducting several clinical trials to validate the long-term results of procedures using our products and to support applications to 
regulatory agencies for expanded indications. In addition, we also conduct various studies to gather clinical data regarding our 
products. Key trials and studies are: 

CONVERGE. We are conducting the CONVERGE IDE clinical trial to evaluate the safety and efficacy of the EPi-Sense 
Guided Coagulation System with VisiTrax technology to treat symptomatic persistent and long-standing persistent Afib patients who 
are refractory or intolerant to at least one Class I and/or III anti-arrhythmic drug. The trial provides for enrollment of up to 153 
patients at 27 domestic medical centers and three international medical centers. Enrollment began in 2014 and was completed in 
August 2018. The study protocol requires patient follow-up for twelve months post procedure for the primary effectiveness endpoint 
assessment and long-term follow-up through five years. The last PMA module was submitted in December 2019. Throughout 2020, 
we have conducted several meetings with FDA as they review our PMA submission, and we continue to actively work with FDA to 
complete the regulatory process. In November 2020, we submitted our responses to FDA, seeking PMA approval of the EPi-Sense 

6 

  
 
system for an indication for treatment of symptomatic, drug-refractory, long-standing persistent atrial fibrillation, when augmented 
with an endocardial ablation catheter. We are currently waiting for feedback from FDA.  

aMAZE. In connection with our acquisition of SentreHEART in August 2019, we are conducting the aMAZE IDE clinical trial. 
aMAZE is an FDA-approved, prospective, multicenter, randomized controlled trial evaluating the LARIAT system for LAA exclusion 
adjunctive to PVI catheter ablation for the treatment of persistent and long-standing persistent Afib. The objective of the aMAZE IDE 
trial is to demonstrate that using the LARIAT system for LAA exclusion, plus a PVI catheter ablation, will lead to a reduced incidence 
of recurrent Afib compared to PVI alone, with a favorable safety profile. The aMAZE IDE trial provides enrollment of up to 600 
patients at 65 sites with one-year follow up. Enrollment was completed in December 2019, and patient follow-up for twelve months 
post PVI catheter ablation required by the study protocol remains ongoing. At this time, we have not experienced a significant delay in 
patient follow-up. However, we are unable to predict the occurrence of future delays as a result of the COVID-19 pandemic. In 
January 2020, we received approval for a CAP for the aMAZE IDE trial. The aMAZE CAP provides for additional patient enrollment 
of up to 85 patients at existing aMAZE IDE trial sites, with the opportunity to further expand to 250 patients while the pre-market 
application is under review. Enrollment in the aMAZE CAP is active and remains ongoing. 

ICE-AFIB. The ICE-AFIB clinical trial is designed to study the safety and efficacy of the cryoICE® system for persistent and 
long-standing persistent Afib treatment during concomitant on-pump cardiac surgery. The trial provides for enrollment of up to 150 
patients at up to 20 sites in the United States. Enrollment began in January 2019 and remains ongoing. 

ATLAS. The ATLAS study is a non-IDE randomized pilot study evaluating outcomes of patients with risk factors for 

developing postoperative Afib as well as risk of bleeding on oral anticoagulation. There are two types of patients subject to this study: 
those with a postoperative Afib diagnosis and receiving prophylactic exclusion of the left atrial appendage with the AtriClip device 
concomitant to cardiac surgery and those with a postoperative Afib diagnosis who are medically managed. Enrollment began in 
February 2016 and ended in March 2018. Preliminary data was presented at the Heart Rhythm Society meeting in May 2019, and a 
manuscript will be drafted after event adjudication is complete and data is analyzed. 

FROST. We have conducted a cryo nerve block study, which was a non-IDE randomized pilot study evaluating intraoperative 

intercostal cryoanalgesia. The study involves treatment arm patients who received intercostal cryoanalgesia in conjunction with 
standard post-operative pain management and control arm patients who receive standard post-operative pain management only. The 
study provided for enrollment of up to 100 patients at five medical centers. Enrollment began in June 2016 and an interim data 
analysis was completed when a total of 80 patients were enrolled in 2019. Enrollment was stopped following the interim analysis due 
to early achievement of statistical significance. Results from the trial were presented at the Society of Thoracic Surgeons podium in 
January 2020. 

DEEP AF Pivotal Study. The DEEP AF IDE pivotal trial evaluates the safety and efficacy of the AtriCure Bipolar System 
when used in a staged approach where a minimally invasive surgical ablation procedure is first performed. The patient undergoes the 
endocardial catheter procedure approximately 91-120 days later. The study began in 2014 and was paused during 2016-2017 due to 
our work to mitigate the risk related to esophageal injury during the procedure. We are committed to patient safety, and we worked 
collaboratively with FDA and obtained approval to resume enrollment in the trial in 2018 starting with 40 patients. All 40 patients 
have been enrolled and treated. A report of the safety data has been submitted to FDA, and we are awaiting their response. We plan to 
seek approval to enroll the full cohort of 220 patients, pending FDA’s review of additional safety data. 

CEASE AF. We are also pursuing a non-IDE trial in Europe to compare staged hybrid ablation treatment (minimally invasive 

surgical ablation procedure is first performed and the patient undergoes the intracardiac catheter procedure approximately 91-180 days 
later) versus catheter ablation alone. Enrollment began in November 2015 and remains ongoing. 

Sales, Marketing and Medical Education  

Our global sales and marketing efforts focus on educating physicians about our unique technologies and their technical benefits. 
We only promote our products for uses described in their labeling as cleared or approved by the relevant regulatory agencies. We train 
our sales force on the use of our products to the extent the products are cleared or approved. 

Our sales team in the United States has approximately 180 employees supporting approximately 54 sales territories. We select 
our sales personnel based on their expertise, sales experience and reputation in the medical device industry, and their knowledge of 
cardiac surgery procedures and technologies. 

We market and sell our products in selected countries outside of the United States through a combination of independent 
distributors and direct sales personnel. Our international sales team includes sales representatives focused on our direct markets, such 
as Germany, France, the United Kingdom and the Benelux region. We also maintain a network of distributors in Asia, South America 
and Canada, as well as certain countries in Europe, who market and sell our products. We continue to evaluate opportunities for 
further expansion into markets outside of the United States.  

7 

  
 
Competition  

Our industry is competitive, subject to change and significantly affected by new product introductions and other activities of 

industry participants. Most of our competitors have greater financial and human resources than we do and have relationships with our 
target customers, as well as worldwide distribution channels that are more established and developed than ours. Our primary 
competitor in the cardiac surgery market is Medtronic, plc, who provides similar products to ours that have been adopted by 
physicians for the treatment of Afib and related conditions. AtriCure’s Isolator Synergy System is the only medical device that is FDA 
approved to treat Afib in a surgical setting, and the only medical device approved to treat persistent or long-standing persistent Afib in 
a concomitant setting. Several other companies offer intracardiac catheter devices that are commonly used by electrophysiologists to 
treat Afib. These catheter devices are FDA-approved to treat the paroxysmal and persistent forms of Afib, but they are not FDA 
indicated to treat long-standing persistent Afib. AtriCure is monitoring other companies who are conducting clinical trials that may 
support FDA approval of their devices to treat persistent and long-standing persistent Afib. We believe that our products compare 
favorably against competing products during both open-heart and minimally invasive procedures, and that our products improve 
treatment outcomes for patients with non-paroxysmal forms of Afib when combined with intracardiac catheter devices. 

To compete effectively, we strive to demonstrate that our products are an attractive alternative or addition to other treatments by 

differentiating our products on the basis of safety, efficacy, performance, ease of use, reputation, service and price. In addition, we 
invest heavily in training and education to ensure that our customers understand available devices, techniques, and approaches for 
optimal treatment. We have encountered and expect to continue to encounter potential customers who prefer products offered by our 
competitors.  

Third-Party Reimbursement 

Payment for patient care in the United States is generally made by third-party payors. These payors include private insurers and 
government insurance programs, such as Medicare and Medicaid. The Medicare program, the largest single payor in the United States, 
is a federal health benefit program administered by the Centers for Medicare and Medicaid Services (CMS) and covers certain medical 
care items and services for eligible beneficiaries, such as individuals over 65 years old, as well as chronically disabled individuals. 
Because Medicare beneficiaries comprise a large percentage of the populations for which our products are used, and private insurers 
may follow the coverage and payment policies for Medicare, Medicare’s coding, coverage and payment policies for cardiothoracic 
surgical procedures are significant to our business.  

Medicare’s Part A program pays hospitals for inpatient services, such as cardiothoracic surgery, under the Inpatient Prospective 

Payment System, which provides a predetermined payment based on the patient’s discharge diagnoses and surgical procedure(s). 
Discharge diagnoses are grouped into Medicare Severity Diagnosis Related Groupings (MS-DRG). There are several cardiac surgery 
MS-DRGs associated with the surgical treatment of Afib, with and without a concomitant open-heart procedure. When an ablation 
device and/or LAA exclusion device (LAAM) is used during a concomitant open-heart procedure, Medicare’s hospital reimbursement 
is based upon the patient’s primary structural heart surgical procedure. Therefore, any additional procedure concomitant to the primary 
procedure would not receive incremental hospital payment. In contrast, sole therapy minimally invasive ablation or surgical LAAM 
procedures typically are reimbursed under a general cardiac surgery MS-DRG. We believe hospital reimbursement rates for sole 
therapy and concomitant therapy cardiac surgical ablation or LAAM are adequate to cover the cost of our products even when 
multiple procedures are performed.  

Physicians are reimbursed for their services separately under the Medicare Part B physician fee schedule. When performing a 

surgical cardiac ablation with and without a concomitant open-heart procedure, surgeons report Current Procedural Terminology 
(CPT) codes to receive a professional fee payment. Multiple CPT codes may be reported by a physician during a procedure if multiple 
procedures are performed. There are category one CPT codes for both concomitant and standalone surgical Afib treatment. At this 
time, there are no category one CPT codes for the physician to report surgical LAAM. However, some providers utilize unlisted CPT 
codes to obtain reimbursement in these situations.  

In addition to the Medicare program, many private payors look to CMS policies as a guideline in setting their coverage policies 

and payment amounts. The current coverage policies of these private payors may differ from the Medicare program, and payment 
rates may be higher, lower, or the same as the Medicare program. In some cases, certain private payors adopt negative coverage 
policies with respect to therapies involving our products. We engage third-party reimbursement consultants that provide support to our 
customers in the event of a coverage denial. 

Outside of the United States, third-party reimbursement varies widely by geography and by the type of therapy in which our 

devices are used. For example, even though a new medical device may have been approved for commercial distribution, we may find 
limited demand for the device until coverage and sufficient reimbursement levels have been obtained from governmental and private 
third-party payors. In addition, some private third-party payors require that certain procedures or the use of certain products be 
authorized in advance as a condition of reimbursement. In some countries, cost containment initiatives and health care reforms include 
initiatives like governmental reviews of reimbursement rate benchmarks, which may significantly reduce reimbursement for 
procedures using our medical devices or deny coverage for those procedures altogether. We are actively working to pursue market 

8 

  
 
access in certain geographies, which includes applying for new reimbursement for therapies in which our devices are being used or 
pursuing specific reimbursement for utilization of our devices.  

Government Regulation  

Our products are medical devices and are subject to regulation in the United States by FDA and other federal agencies, and by 

comparable authorities in the European Union (EU) and other countries worldwide. 

US Regulation: 

FDA regulations govern nearly all of the activities that we perform, or that are performed on our behalf, to ensure that medical 

products distributed domestically or exported internationally are safe and effective for their intended uses. FDA regulates the total 
product lifecycle from early design, development and testing, to manufacturing and commercialization activities, as well as post-
market surveillance and reporting, including corrective actions, removals and recalls. Unless an exemption applies, most medical 
devices distributed in the United States require either 510(k) clearance or PMA from FDA.  

510(k) Clearance Pathway. To obtain 510(k) clearance, we must submit a notification to FDA demonstrating that our proposed 

device is substantially equivalent to a predicate device, i.e., a previously cleared and legally marketed 510(k) device or a device that 
was in commercial distribution before May 28, 1976, for which FDA has not yet called for the submission of a PMA. Any 
modification to a 510(k)-cleared device that would constitute a major change in its intended use, or a change in its design or 
manufacture that could significantly affect the safety or effectiveness of the device, requires a new 510(k) clearance.  

Premarket Approval Pathway. A PMA must be submitted to FDA if the device cannot be cleared through the 510(k) process 
and is not otherwise exempt. A PMA must be supported by extensive data, including but not limited to technical, preclinical, clinical, 
manufacturing and labeling, to demonstrate the safety and effectiveness of the device for its intended use. A PMA supplement is 
required for changes affecting the safety or effectiveness of a PMA-approved device, including but not limited to new indications for 
use, a different manufacturing facility, or changes in the manufacturing process, labeling, or design specifications or components of 
the device. 

Clinical Trials. Clinical trials are required to support a PMA and are sometimes required for 510(k) clearance. Clinical trials are 

subject to extensive recordkeeping and reporting requirements. Our clinical trials must be conducted under the oversight of an 
Institutional Review Board (IRB) for the relevant clinical trial sites and must comply with FDA regulations, including, but not limited 
to, those relating to current good clinical practices. We are also required to obtain the written informed consent of patients in form and 
substance that complies with both FDA requirements and other human subject protection regulations established by FDA. We must 
conduct our clinical studies in compliance with state and federal privacy laws, including the Health Insurance Portability and 
Accountability Act (HIPAA).  

Educational Grants. FDA regulates the promotion of medical devices by manufacturers and prohibits the promotion of uses 

that are not on the approved or cleared labeling of the device. FDA does not regulate the practice of medicine or the conduct or 
content of medical education conducted by third parties, which may include uses that are not on approved or cleared device labeling, 
referred to as “off-label” uses. Manufacturers may provide unrestricted financial support for independent third-party medical 
education programs in the form of educational grants intended to offset the cost of such programs. If the manufacturer controls or 
unduly influences the content of such programs, FDA considers those programs to be promotional activities by the manufacturer and 
thus subject to FDA regulation including promotional restrictions. We seek to ensure that our educational grants program is conducted 
in accordance with FDA criteria for independent educational activities. However, we cannot provide an assurance that FDA or other 
government authorities would view the third-party programs we have supported as being independent.  

Pervasive and Continuing Regulation. There are numerous regulatory requirements that apply after a product is cleared or 
approved by FDA, including, but not limited to: annual establishment registration and product listing; current good manufacturing 
practice for devices, referred to as the Quality System Regulation (QSR); labeling requirements, and advertising and promotion 
guidelines, assessing the significance of any changes to a device, monitoring and reporting serious and adverse events and certain 
device malfunctions, and reporting certain device corrections and removals. Our manufacturing facilities and processes are also 
subject to FDA inspections to ensure compliance with QSR. 

In addition to FDA regulation, the advertising and promotion of certain medical devices are also regulated by the Federal Trade 
Commission and by state regulatory and enforcement authorities. On occasion, promotional activities for FDA-regulated products can 
be the subject of enforcement action brought under healthcare reimbursement laws and consumer protection statutes. In addition, 
under the Federal Lanham Act and similar state laws, competitors and others can initiate litigation relating to advertising claims.  

Fraud, Abuse and False Claims. We are directly and indirectly subject to various federal and state laws governing our 

relationship with healthcare providers. In particular, the Anti-Kickback Statute is a federal criminal law that applies broadly and 
prohibits the knowing and willful offer or payment of remuneration to induce or reward patient referrals or the generation of business 
involving any item or service payable by a federal health care program. The federal False Claims Act (FCA) imposes civil liability on 

9 

  
 
any person or entity that submits, or causes the submission of, a false or fraudulent claim to the United States government. Damages 
under the FCA consist of the imposition of fines and penalties and can be significant. The FCA also allows a private individual or 
entity with knowledge of past or present fraud against the federal government to sue on behalf of the government to recover the civil 
penalties and treble damages. 

AtriCure is a member of the Advanced Medical Technology Association (AdvaMed), a voluntary United States trade 
association for medical device manufacturers. This association has established guidelines and protocols for medical device 
manufacturers in their relationships with healthcare professionals on matters including research and development, product training and 
education, grants and charitable contributions, support of third-party educational conferences and consulting arrangements. Adoption 
of the AdvaMed Code of Ethics for Interactions with Healthcare Professionals (the “AdvaMed Code”) by a medical device 
manufacturer is voluntary, and while the Office of the Inspector General and other federal and state healthcare regulatory agencies 
encourage its adoption and may look to the AdvaMed Code, they do not view adoption of the AdvaMed Code as proof of compliance 
with applicable laws. We have adopted the AdvaMed Code and incorporated its principles in our standard operating procedures, 
employee training programs, and relationships with medical professionals. 

Regulation Outside of the United States:  

Sales of medical devices outside of the United States are subject to foreign governmental regulations which vary substantially 
from country to country. The time required to obtain certification or approval by a foreign country may be longer or shorter than that 
required for FDA clearance or approval and the requirements may be different, but the general trend is toward increasing regulation 
and greater requirements for the manufacturer to provide more bench testing and clinical evidence.  

While some harmonization of global regulations has occurred, requirements continue to differ significantly. In China, for 
example, the product must first have approval in the country of origin. In China, successful results from local product safety testing 
precedes submission of documentation to obtain approval. In addition, regulatory agencies and authorities can halt distribution within 
the country or otherwise take action in accordance with local laws. 

Conformity Assessment Pathway. In the European Union, various directives regulate the design, manufacture and labeling of 

medical devices, and more stringent conformity assessment requirements have been put in place with the 2017 Medical Device 
Regulation, effective May 26, 2021. The method for assessing conformity varies depending on the type and class of the product, but 
typically involves a combination of quality system assessment and product conformity assessment by a third-party notified body, an 
independent and neutral institution appointed by a country to conduct the conformity assessment. This third-party assessment includes 
a review of documentation related to the device that may be as extensive as the documentation requirements that the United States 
FDA requires for higher risk products. The notified body also audits the manufacturer’s quality system and performs a detailed review 
of the testing of the manufacturer’s device. Successful completion of a conformity assessment procedure allows a manufacturer to 
issue a declaration of conformity with the requirements of the relevant directive and affix the CE mark to the device. Devices that bear 
the CE mark may be commercially distributed throughout the member states of the European Union and other countries that comply 
with or mirror the medical device directives or medical device regulations. 

Pervasive and Continuing Regulation. There are numerous regulatory requirements that apply after a product has been 
approved by the notified body for CE marking, including, but not limited to: labeling, advertising and promotion, reporting of device 
modifications, monitoring the safety of the product and performing corrections and removals when necessary, maintaining “state of 
the art” requirements for the devices through compliance with standards, and obtaining recertification of the quality system and 
individual device certificates on a periodic basis. 

Intellectual Property  

Protection of our intellectual property is a priority for our business, and we rely on a combination of patent, copyright, 
trademark and trade secret laws to protect our interests. Our ability to protect and use our intellectual property rights in the continued 
development and commercialization of our technologies and products, operate without infringing the proprietary rights of others, and 
prevent others from infringing our proprietary rights is important to our continued success. We will be able to protect our products and 
technologies from unauthorized use by third parties only to the extent that they are covered by valid and enforceable patents, 
trademarks or copyrights, or are effectively maintained as trade secrets, know-how or other proprietary information.  

We hold numerous issued United States and international patents. We also have multiple pending United States and 

international patent applications. We seek patent protection relating to technologies and products we develop in both the United States 
and in selected foreign countries. While we own much of our intellectual property, including patents, patent applications, trademarks, 
trade secrets, know-how and proprietary information, we also license patents and related technology of importance to the 
commercialization of our products. To continue developing and commercializing our current and future products, we may license 
intellectual property from commercial or academic entities to obtain the rights to technology that is required for our research, 
development and commercialization activities.  

10 

  
 
All of our employees and technical consultants are required to execute confidentiality agreements in connection with their 
employment and consulting relationships with us. We also generally require them to agree to disclose and assign to us all inventions 
conceived in connection with their relationship with us. We devote significant resources to obtaining patents and other intellectual 
property and protecting our other proprietary information. If valid and enforceable, these patents may give us a means of blocking 
competitors from using infringing technology to compete directly with our products. We also have proprietary information that may 
not be patentable. With respect to proprietary information that is not patentable, we have chosen to rely on trade secret protection and 
confidentiality agreements to protect our interests.  

Manufacturing  

We assemble, inspect, test and package the majority of our products at our facilities in Ohio and California, and our products are 

sterilized by third parties. Purchased components are generally sourced from a single supplier, but alternatives to these suppliers are 
available in the event this would be needed.  

To minimize supply chain risks, we maintain inventory levels of components and raw materials specific to the respective part or 
device. We assess tooling and equipment on an ongoing basis. Order quantities and lead times for components purchased from outside 
suppliers are based on our forecasts derived from historical demand and anticipated future demand. Lead times may vary significantly 
depending on the size of the order, time required to fabricate and test the components, specific supplier requirements and current 
market demand for the components and subassemblies. To date, we have not experienced significant delays in obtaining any of our 
components. 

We regularly audit our suppliers for compliance with our quality system requirements, the QSR and/or applicable ISO 

standards. We are an FDA-registered medical device manufacturer and certified to ISO 13485:2016. In addition, we have successfully 
participated in the Medical Device Single Audit Program (MDSAP) and have been certified accordingly. The MDSAP program is 
recognized in Australia, Brazil, Canada, Europe, Japan and the United States. 

We are subject to numerous federal, state and local laws relating to such matters as laboratory practices, the experimental use of 

animals, the use and disposal of hazardous or potentially hazardous substances, safe working conditions, manufacturing practices, 
environmental protection and fire hazard control.  

Consulting Relationships  

We have developed consulting relationships with scientists and physicians throughout the world to support our research and 
development, clinical and training and education programs. We work closely with these thought leaders to understand unmet needs 
and emerging applications for the treatment of Afib. 

Our physician consulting agreements are intended to satisfy the requirements of the personal services “Safe Harbor” regulation 

as well as the AdvaMed Code and the MedTech Europe Code of Ethical Business Practice. As such, they provide for payment of a fair 
market value fee only for legitimate services rendered to us. We do not expect or require the consultant to utilize or promote our 
products, and consultants are required to disclose their relationship with us as appropriate, such as when publishing an article in which 
one of our products is discussed. Amounts paid to physicians in the United States are disclosed by us in annual reports submitted to 
CMS under the federal “Open Payments” law. Amounts paid to physicians in certain other countries are also disclosed by us in reports 
submitted to various governmental agencies in those countries, in accordance with the laws of the jurisdictions where those physicians 
reside or practice, or where the payments are made. 

Human Capital Management  

Successful execution of our strategy is dependent on attracting, developing and retaining key employees and members of our 

management team. The skills, experience, and industry knowledge of our employees significantly benefit our operations and 
performance. We continuously evaluate, modify, and enhance our internal processes to increase employee engagement, productivity, 
and efficiency. 

We had approximately 750 employees as of January 31, 2021. None of the employees were represented by a labor union or 

covered by a collective bargaining agreement. We have never experienced any employment-related work stoppages and consider our 
employee relations to be in good standing. At AtriCure, the employee experience is crucial to the ongoing success of the company. We 
work to provide a culture that augments the intrinsic rewards of our mission – one where employees feel valued and supported every 
day. We strive to communicate with transparency, engage at every level, and share in personal milestones. Our culture provides 
opportunities for employees to feel a part of a community through paid leave for volunteering and individual recognition with “Heart 
of AtriCure” awards. Our employees have voted us as a Top Workplace five times, and our culture is regularly cited in our internal 
engagement surveys as a leading positive attribute of the company. Our culture is a central asset to our company. 

Employee Compensation and Benefits 

Competitive compensation and benefits are an integral part of attracting world-class talent to our organization. We are 
committed to regularly analyzing and evaluating the effectiveness of our compensation and benefit programs and benchmarking our 

11 

  
 
programs against the market and our industry peers. Annual pay increases and incentive compensation are based on performance, 
which is communicated to employees and documented through our annual talent review and management process, as well as upon 
internal transfer and/or promotion.  

All U.S.-based employees are eligible for medical, dental, and vision insurance, paid leave for both vacation and illness, a 
401(k) plan that includes a discretionary company matching contribution, a stock purchase plan enabling employees to purchase 
AtriCure stock at a reduced price, life and AD&D insurance, and short- and long-term disability coverage. We also offer a variety of 
ancillary benefits as enhancements, such as critical illness and accident coverage, telemedicine, adoption assistance, paid time off to 
volunteer, tuition reimbursement, and a wellness program. International benefits are aligned with local market offerings. 

Diversity, Equity, and Inclusion 

We have an ongoing commitment to advancing Diversity, Equity, and Inclusion (DE&I) throughout our workplace and the 

communities in which we operate. By honoring the dignity of each person, we foster a culture of inclusion where everyone is 
welcome. We do this by embracing diverse voices and experiences, supporting programs and resources that build an authentic and 
respectful workplace, and providing fair and equitable opportunities for each person to contribute meaningfully in both their work and 
their personal lives. We believe that everyone should feel confident in bringing their authentic selves to work and contribute to our 
mission. 

We believe our workforce needs to be diverse, and leverage the skills and perspectives of a variety of backgrounds and 
experiences. To attract a global workforce, we strive to embed a culture where employees can bring their whole selves to work. In 
addition to established and ongoing workplace harassment training, we recently have expanded our DE&I training company-wide, as 
well as into new hire orientation, established DE&I committees with employee volunteers, and expanded recruitment outreach to 
include more organizations, societies, and sources that serve minority communities. In 2020, we provided a paid half-day holiday to 
all U.S. employees on election day, to offer ample opportunity for voting, and for 2021, we added Martin Luther King Jr. Day as a 
designated AtriCure U.S. holiday. We have also recently hired a Diversity, Equity, and Inclusion leader to further advance our 
commitment and programs. 

Training and Development 

Employee training and development is a priority at AtriCure. We strive to create an environment where employees can realize 
their potential. We provide a range of training courses and online resources, as well as developmental coaching and mentoring. We 
have a regular monthly schedule of opportunities that allows employees to access both instructor-led classrooms and self-directed 
web-based courses. We are committed to identifying and developing the talents of our next-generation leaders. On an annual basis, we 
conduct a 9-Box Leadership Review, a process in which our Executive Leadership Team and Vice Presidents are closely involved. In 
that process, we review existing leaders and prospective leaders throughout the organization and determine next best steps for their 
future development. Developmental plans for employees can range from leadership support to technical skill-building. 

We also work to ensure all employees have access to training that is consistent with the competencies that are measured as part 

of performance management: Delivering Results with Accountability, Initiative and Involvement, Teamwork and Support, and for 
those who manage people, Develop and Maintain High Performance Teams and Communication. 

Safety for All Employees 

We are committed to maintaining a safe workplace and promoting the well-being of all of our employees. We have 
implemented multiple safety programs and regularly perform safety hazard evaluations within our facilities. Programs include our 
Emergency Site Action Plan for emergencies such as fire response, severe weather threats and shelter in place incidents, as well as our 
Certified First Responders safety program that include Red Cross training of employees in CPR, AED Usage and First Aid practices. 
We recognize that the use of tobacco is linked to many adverse health effects, including those that impact the heart, and we offer our 
employees tobacco cessation programs. Effective January 1, 2021, our Ohio office locations are entirely tobacco- and nicotine-free, 
and to the extent permitted in the states of our other offices, those locations are also entirely tobacco- and nicotine-free.  

Throughout the COVID-19 pandemic, our employees have been our first and foremost focus. We have implemented a number 
of measures to provide a safe work environment for our employees. Most of our office-based employees began working remotely in 
March 2020, while field-based sales and clinical employees continue to support cases, utilizing technology to engage with customers 
in virtual settings when physical access is prohibited. We have modified our manufacturing operations in order to adhere to social 
distancing requirements dictated by local law and have taken measures to help ensure safety, including requiring temperature checks 
for employees entering our facilities, wearing face coverings, and other best practices surrounding hygiene to mitigate the spread of 
viruses by our employees. We have not implemented any temporary or permanent reductions in headcount or to non-executive 
employee compensation. AtriCure has provided regular, mandatory training for all employees on COVID-19 protocols that are 
consistent with Center for Disease Control recommendations and state and country-specific guidelines. Such protocols and guidance is 
continually updated and made available to employees. We have also established decision-making protocols for contact tracing, return 
to work, and sanitization.

COVID-19 Pandemic Risks 

The outbreak of coronavirus (COVID-19) is materially and adversely affecting demand for our products and with 
prolonged delays, could continue to affect the demand for our products and impact our clinical trials, causing disruption to 
our business and negatively impacting our results of operations and financial condition. 

We are subject to risks related to public health crises such as the global pandemic associated with COVID-19. On January 30, 

2020, the World Health Organization declared that the recent coronavirus COVID-19 outbreak was a global health emergency, and on 
March 11, 2020, declared it to be a pandemic. The COVID-19 outbreak has negatively impacted and is expected to continue to 
negatively impact our operations and revenues and overall financial condition by significantly decreasing the number of procedures 
performed with our products. The number of procedures performed has significantly decreased as health care organizations globally 
have deferred non-emergent procedures to preserve resources and prioritized the treatment of patients with COVID-19 and protect 
patients from potential exposure to COVID-19. For example, in the United States, governmental authorities have recommended, and 
in certain cases required, that elective, specialty and other procedures and appointments, be suspended or canceled to avoid non-
essential patient exposure to medical environments and potential infection with COVID-19 and to focus limited resources and 
personnel on the treatment of COVID-19. These measures and challenges will likely continue for the duration of the pandemic, which 
is uncertain, and will significantly reduce our revenue while the pandemic continues.  

Numerous state and local jurisdictions have imposed, and others in the future may impose, “shelter-in-place” orders, quarantines, 

executive orders and similar government orders and restrictions for their residents to control the spread of COVID-19. Such orders or 
restrictions have resulted in slowdowns and delays, travel restrictions and cancellation of events, among other effects. Other 
disruptions or potential disruptions include restrictions on our personnel and partners to travel and access customers for training and 
case support; delays in approvals by regulatory bodies; delays in product development efforts; and additional government 
requirements or other incremental mitigation efforts that may further impact our or our suppliers’ capacity to manufacture, sell and 
support the use of our products.  

We may experience diversion of healthcare resources away from the conduct of clinical trials, including the diversion of 
hospitals serving as our clinical trial sites. Key clinical trial activities, such as clinical trial site monitoring, subject visits and study 
procedures, may be interrupted due to limitations imposed or recommended by federal or state governments, trial sites, employers or 
others. We may also encounter interruption or delays in the operations of FDA or other regulatory authorities, which may impact 
review and approval timelines. 

In addition, the COVID-19 pandemic may impact the trading price of shares of our common stock and could impact our 

ability to raise additional capital on a timely basis or at all.  

The COVID-19 pandemic continues to rapidly evolve. The extent to which COVID-19 may impact our business, including 

our nonclinical activities, clinical trials and financial condition, will depend on future developments, which are highly uncertain, such 
as the geographic spread of the disease, the duration of the pandemic, travel restrictions, business closures or business disruptions and 
the effectiveness of actions taken to contain and treat the disease. To the extent the COVID-19 pandemic adversely affects our 
business and financial results, it may also have the effect of heightening many of the other risks set forth in this “Risk Factors” 
section. 

Commercial Execution and Product Performance Risks 

If our products do not achieve widespread market acceptance in the United States, our operating results will be harmed, and 
we may not achieve or sustain profitability.  

Our success depends in large part on the medical community’s acceptance of our products in the United States, which is the 
largest revenue market in the world for medical devices. Our ablation and our LAA management product sales in the United States 
generate the majority of our revenue. We expect that sales of these products will continue to account for a majority of our revenue for 
the foreseeable future and that our future revenue will depend on the increasing acceptance by the medical community of our products 
as standard of care for treating Afib and managing the LAA. The U.S. medical community’s acceptance of our products will depend 
upon our ability to demonstrate the safety and efficacy, advantages, long-term clinical performance and cost-effectiveness of our 
products. In addition, acceptance of products for the treatment of Afib is dependent upon, among other factors, the level of awareness 
and education of the medical community about the surgical treatment of Afib and the existence, effectiveness and safety of our 
products. Market acceptance and adoption of our products for the treatment of Afib also depends on the level of health insurer 
(including Medicare) reimbursement to physicians and hospitals for procedures using our products. Negative publicity resulting from 
incidents involving our products, or similar products could have a significant adverse effect on the overall acceptance of our products. 
If we encounter difficulties growing the market for our products in the U.S., we may not be able to increase our revenue enough to 
achieve or sustain profitability, and our business and operating results will be seriously harmed. 

16 

  
 
 
 
Competition from existing and new products and procedures may decrease our market share and may cause our revenue to 
decline, and could adversely affect our operating results. 

The medical device industry, including the market for the treatment of Afib, is highly competitive, is subject to rapid 

technological change and can be significantly affected by new product introductions and promotional activities. There is no assurance 
that our products will compete effectively against drugs, catheter-based ablation, implantable devices, other surgical ablation devices, 
or other products or techniques to occlude the left atrial appendage. Our products may become obsolete prior to the end of their 
anticipated useful lives, or we may introduce new products or next-generation products prior to the end of the useful life of our current 
products, either of which may require us to dispose of existing inventory and related capital equipment and/or write off their value or 
accelerate their depreciation. In addition, other products may be sold at lower prices. Due to the size of the Afib and LAA 
management markets, we anticipate that new or existing competitors may develop competing products, procedures and/or clinical 
solutions. There are few barriers to prevent new entrants or existing competitors from developing products to compete directly with 
ours. Companies also compete with us to attract qualified scientific and technical personnel as well as funding. Most of our 
competitors and potential competitors have greater financial, manufacturing, marketing and research and development capabilities 
than we have, and may obtain FDA approval or clearance for their products before we do. The introduction of new products, 
procedures or clinical solutions, or our competitors obtaining FDA approvals or clearances, may result in price reductions, reduced 
margins, loss of market share, or may render our products obsolete, which could adversely affect our revenue and future profitability. 

Any clinical data that is generated regarding our products may not be positive, and our current and planned clinical trials 
may not satisfy the requirements of the FDA or other regulatory authorities. 

Our clinical trials are expensive to conduct, typically taking many years to complete, and have uncertain outcomes. Delays in 

patient enrollment or failure of patients to consent or continue to participate in a clinical trial may cause an increase in costs and 
delays in the approval and attempted commercialization of our products or result in the failure of the clinical trial. Conducting 
successful clinical studies may require the enrollment of large numbers of clinical sites and patients, and suitable patients may be 
difficult to identify and recruit. Patient enrollment in clinical trials and completion of patient participation and follow-up depends on 
many factors, including the size of the patient population; the nature of the trial protocol; the attractiveness of, or the discomforts and 
risks associated with, the treatments received by enrolled subjects; the availability of appropriate clinical trial investigators, support 
staff, and proximity of patients to clinical sites; and the ability to comply with the eligibility and exclusion criteria for participation in 
the clinical trial and patient compliance.  

Our products will be measured on their efficacy which is dependent on the number of patients that experience Afib or stroke 
following treatment with our products and the number of patients that have serious complications resulting from ablations or LAA 
exclusion using our products. We cannot provide any assurance that the data collected during our clinical trials will be compelling to 
the medical community because it may not be scientifically meaningful, may identify unexpected safety concerns, and may not 
demonstrate that procedures utilizing our products are an attractive option when compared against data from alternative procedures 
and products. Negative data would affect the use of our products and harm our business and prospects.  

Conversely, positive results from clinical trial experience should not be relied upon as evidence that any of our clinical trials 

will succeed or that they will satisfy regulatory requirements for product approval. There can be no assurance that the results of studies 
conducted by collaborators or other third parties will be viewed favorably or are indicative of our own future study results. We may be 
required to demonstrate with substantial evidence through well-controlled clinical trials that our product candidates are either (i) safe 
and effective for use in a diverse population for their intended uses or (ii) are substantially equivalent to predicate devices under 
section 510(k) of the Food, Drug and Cosmetic Act. Success in early clinical trials does not mean that future clinical trials will be 
successful because product candidates in later-stage clinical trials may fail to demonstrate sufficient safety and efficacy to the 
satisfaction of the FDA and other regulatory authorities despite having progressed through initial clinical trials.  

Our devices and products may not be approved or cleared even though clinical or other data, in our view, are adequate to 

support an approval or clearance. The FDA or other regulatory authorities may: 
• 
• 

disagree with our trial design and our interpretation of data from pre-clinical studies and clinical trials;  

change requirements for the approval or clearance of a product candidate even after reviewing and providing comment on a 
protocol for a pivotal clinical trial; 

• 
• 
• 

approve or clear a product candidate for fewer or more limited indications or uses than we request; 

grant approval or clearance contingent on the performance of costly post-marketing clinical trials; or 

not approve the labeling claims necessary or desirable for the successful commercialization of our product candidates.  

These factors would affect the rate at which our products are adopted in the medical community. 

Our success depends, in part, on our ability to achieve FDA pre-market approval of the EPi-Sense device for the treatment of 
Afib and the commercial success of this product. 

On May 8, 2020, we announced the results from the CONVERGE IDE clinical trial. The CONVERGE trial achieved its 

primary efficacy endpoint with an approximately 18% difference in favor of the hybrid Convergent procedure as compared to 
standalone endocardial catheter ablation. 

17 

  
 
The CONVERGE trial primary efficacy endpoint is freedom from Afib, atrial tachycardia (AT), and atrial flutter (AFL), 

absent class I and III anti-arrhythmic drugs (AADs) except for a previously failed or demonstrated intolerance to class I or III AADs, 
with no increase in dosage following the 3-month blanking period through the 12 months post procedure follow-up visit. The primary 
safety endpoint is the incidence of major adverse events (MAEs) specified in the protocol for subjects undergoing the Convergent 
procedure from the time of the intervention through 30-days post intervention. There were no deaths, cardiac perforations, or atrio-
esophageal fistulas reported in the CONVERGE trial, and the MAE rate of 7.8% in the treatment arm is lower than the protocol pre-
specified performance goal of 12%. However, there can be no assurance that the FDA will grant pre-market approval of the EPi-Sense 
device based on this data. 

Although our CONVERGE IDE device is currently cleared under section 510(k), we are also pursuing a PMA from the FDA. 

The process for obtaining marketing approval from the FDA or similar foreign governmental agencies is both time-consuming and 
costly, with no certainty of a successful outcome. The last module of the PMA application was submitted to FDA in December 2019. 
Throughout 2020, we have conducted several meetings with FDA as they review our PMA submission to complete the regulatory 
process. In November 2020, we submitted our responses to questions posed by FDA, seeking PMA approval of the EPi-Sense system 
for an indication for treatment of symptomatic, drug-refractory, long-standing persistent atrial fibrillation, when augmented with an 
endocardial ablation catheter. There can be no assurance that we will obtain a pre-market approval for the EPi-Sense device on a 
timely basis, or at all. If we are unable to achieve pre-market approval for the EPi-Sense device, our business will be significantly 
adversely impacted, which could have a materially adverse effect on our business, financial condition and results of operations. 

Our success is dependent on our ability to train surgeons in the safe and effective use of our products. Restrictions on our 
ability to train surgeons, or unwillingness of surgeons to participate in such training, could reduce the market acceptance of 
our products. 

Our research and development efforts and our marketing strategy depend heavily on obtaining support, physician training 

assistance and collaboration from experienced physicians at leading commercial and research hospitals, particularly in the U.S. and 
Europe. We deliver training on the safe and effective use of our products consistent with their FDA (or equivalent regulatory body) 
approved or cleared indications. While we train providers in the safe and effective use of our products, we do not train them to use any 
of our products specifically to treat Afib unless the product is FDA-approved specifically for the treatment of Afib. In order for 
surgeons to learn to use our products, they must attend training sessions to familiarize themselves with the products, and they must be 
committed to learning the technology. Further, surgeons must utilize the technology on a regular basis to ensure they maintain the skill 
set necessary to use the products. Continued market acceptance could be delayed by lack of surgeon willingness to attend training 
sessions, by the time required to complete this training or by state or institutional restrictions on our ability to provide training. If we 
are unable to gain and/or maintain such support, training services and collaboration, our ability to market our products and, as a result, 
our financial condition, results of operations and cash flow, could be materially and adversely affected. 

We rely on independent distributors to market and sell our products in certain markets outside of the United States, and a 
failure of our independent distributors to successfully market our products or any disruption in their ability to do so may 
adversely impact our sales.  

We depend on independent third-party distributors to sell our products in certain markets outside of the United States, and if 
these distributors do not perform, we may be unable to maintain or increase international revenue. We intend to grow our business 
outside of the United States, and to do so, we will need to attract additional distributors or hire direct sales personnel to expand the 
territories in which we sell our products. Independent distributors may terminate their relationship with us or devote insufficient sales 
efforts to our products. We are not able to control our independent distributors, and they may not be successful in marketing our 
products. In addition, many of our independent distributors outside of the United States initially obtain and maintain foreign regulatory 
approval for sale of our products in their respective countries. Our failure to maintain our relationships with our independent 
distributors outside of the United States, or our failure to recruit and retain additional skilled independent distributors in these 
locations, could have an adverse effect on our operations. Turnover among our independent distributors, even if replaced, may 
adversely affect our short-term financial results while we transition to new independent distributors or direct sales personnel. The 
ability of these independent distributors to market and sell our products could also be adversely affected by unexpected events, 
including, but not limited to, power failures, nuclear events, natural or other disasters and war or terrorist activities. In addition, the 
ability of our independent distributors to borrow money from their existing lenders or to obtain credit from other sources to purchase 
our products may be impaired or our independent distributors could experience a significant change in their liquidity or financial 
condition, all of which could impair their ability to distribute our products and eventually lead to distributor turnover, and may 
adversely impact our sales.  

Industry Conditions Risks 

Healthcare costs have risen significantly over the past decade. There have been and may continue to be proposals by 
legislators, regulators and third-party payors to keep, contain or reduce healthcare costs.  

The continuing efforts of governments, insurance companies and other payors of healthcare costs to contain or reduce these 
costs, combined with closer scrutiny of such costs, could lead to patients being unable to obtain approval for payment from these 
third-party payors. The cost containment measures that healthcare providers are instituting both in the U.S. and internationally could 
harm our business. Some healthcare providers in the U.S. have adopted or are considering a managed care system in which the 

18 

  
 
providers contract to provide comprehensive healthcare for a fixed cost per person. Healthcare providers may attempt to control costs 
by authorizing fewer elective surgical procedures or by requiring the use of the least expensive devices possible, which could 
adversely affect the demand for our products or the price at which we can sell our products. Some healthcare providers have sought to 
consolidate and create new companies with greater market power, including hospitals. As the healthcare industry consolidates, 
competition to provide products and services has become and will continue to become more intense. This has resulted and likely will 
continue to result in greater pricing pressures and the exclusion of certain suppliers from important marketing segments. 

Adverse changes in payors’ policies toward coverage and reimbursement for surgical procedures would harm our ability to 
promote and sell our products.  

Third-party payors are increasingly exerting pressure on medical device companies to reduce their prices. Even to the extent that 
the use of our products is reimbursed by private payors and governmental payors, adverse changes in payors’ policies toward coverage 
and reimbursement for surgical procedures would also harm our ability to promote and sell our products. Payors continue to review 
their policies and can, without notice, deny coverage for treatments that include the use of our products. Because each third-party 
payor individually approves coverage and reimbursement, obtaining these approvals may be time-consuming and costly. In addition, 
third-party payors may require us to provide scientific and clinical support for the use of our products. Adverse changes in coverage 
and reimbursement for surgical procedures could harm our business and reduce our revenue. 

FDA does not regulate the practice of medicine. Physicians may use our products in circumstances where they deem it 
medically appropriate, such as for the treatment of Afib or the reduction in stroke risk, even though FDA may not have approved or 
cleared our products to be marketed specifically for those indications. Some payors may deny coverage or payment for the use of our 
products for indications not specifically approved or cleared by FDA. Often, these denials can be overcome through an appeals 
process, but there is no guarantee of success in these cases. 

If coverage and adequate levels of reimbursement from governmental and third-party payors outside of the United States are 
not obtained and maintained, sales of our products outside of the United States may decrease, and we may fail to achieve or 
maintain significant sales outside of the United States.  

Our revenue generated from sales outside of the United States is also dependent upon coverage and reimbursement within 
prevailing foreign healthcare payment systems. Foreign healthcare payors generally do not provide the same level of reimbursement 
for sole-therapy minimally invasive procedures utilizing ablation devices and related products as payors in the United States. In 
addition, healthcare cost containment efforts similar to those we face in the United States are prevalent in many of the other countries 
in which we sell our products, and these efforts are expected to continue. To the extent that the use of our devices has historically 
received reimbursement under a foreign healthcare payment system, such reimbursement, if any, has typically been significantly less 
than the reimbursement provided in the United States. If coverage and adequate levels of reimbursement from governmental and third-
party payors outside of the United States are not obtained and maintained, sales of our products outside of the United States may 
decrease, and we may fail to achieve or maintain significant sales outside of the United States.  

Operational Risks 

We may experience unfavorable publicity relating to our business and our industry. This publicity could have a negative 
impact on our ability to attract and retain customers, our sales, clinical studies involving our products, our reputation and our 
stock price. 

We may experience a negative impact on our business from newspaper articles or other media reports relating to, among other 
things, our compliance with FDA regulations for medical device reporting, adverse patient and clinical outcomes and concerns over 
disclosure of financial relationships between us and our consultants. We believe that such publicity would potentially have a negative 
impact on our clinical studies, business, results of operations and financial condition or cause other adverse effects, including a decline 
in the price of our stock. 

We rely upon single and limited source third-party suppliers and third-party logistics providers, making us vulnerable to 
supply problems and price fluctuations which could harm our business.  

We rely on single and limited source third-party vendors for the manufacture and sterilization of components used in our 
products. For example, we rely on one vendor to manufacture several of our RF generators, as well as separate vendors to manufacture 
our EPi-Sense Guided Coagulation System with VisiTrax technology and related RF generator. It would be a time consuming and 
lengthy process to secure these products from an alternative supplier. We have significant concentrations with a limited number of 
vendors. We also rely on a third party to handle our warehousing and logistics functions for European and Middle Eastern markets on 
our behalf.  

Our reliance on outside manufacturers, sterilizers and suppliers also subjects us to risks that could harm our business, including:  

•  we may not be able to obtain adequate supply in a timely manner or on commercially reasonable terms;  
•  we may have difficulty timely locating and qualifying alternative suppliers;  
• 

switching components may require product redesign and new submissions to FDA which could significantly delay production or, 

19 

  
 
if FDA refuses to approve the changes, completely eliminate our ability to sell our products;  

• 

• 

our suppliers manufacture products for a range of customers, and fluctuations in demand for the products those suppliers 
manufacture for others may affect their ability to deliver components to us in a timely manner; and  

our suppliers may encounter financial hardships unrelated to our demand for components, which could inhibit their ability to 
fulfill our orders and meet our requirements.  

Identifying and qualifying additional or replacement suppliers for any of the components used in our products or a replacement 
warehousing and logistics provider, if required, may not be accomplished quickly and could involve significant additional costs. Any 
interruption or delay in the supply of components, materials or warehousing and logistics, or our inability to obtain components or 
materials from alternate sources at acceptable prices in a timely manner, could impair our ability to meet the demand of our customers 
and cause them to cancel orders or switch to competitive products and could therefore have a material adverse effect on our business, 
financial condition and results of operations. 

Our manufacturing operations are primarily conducted at a single location, and any disruption at our manufacturing facility 
could increase our expenses and decrease our revenue. 

Our manufacturing operations are primarily conducted at a single location in Ohio, with select products manufactured in 
California. While we take precautions at the Ohio location, we do not maintain a backup manufacturing facility, making us dependent 
on the current facility and production workers for the continued operation of our business. A natural or other disaster could damage or 
destroy our manufacturing equipment and cause substantial delays in our manufacturing operations, which could lead to additional 
expense and decreased revenue due to lack of supply. The insurance we maintain may not be adequate to cover our losses. With or 
without insurance, damage to our facility or our other property due to a natural disaster or casualty event could have a material adverse 
effect on our business, financial condition and results of operations. 

Our business growth strategy involves the potential for significant acquisitions. Acquisitions have inherent uncertainties and 
involve risks and difficulties in integrating that may adversely affect our business, results of operations and financial 
condition.  

All acquisitions involve inherent uncertainties, which may include, among other things, our ability to:  

• 
• 
• 
• 
• 

successfully identify targets for acquisition;  

negotiate reasonable terms;  

properly perform due diligence and determine significant risks associated with a particular acquisition;  

properly evaluate target company management capabilities; and  

successfully transition and integrate the acquired company into our business and achieve the desired performance. 

We may acquire businesses with unknown liabilities, contingent liabilities or internal control deficiencies. We have plans and 

procedures in place to conduct reviews of potential acquisition candidates for compliance with applicable regulations and laws prior to 
acquisition. Despite these efforts, realization of any of these liabilities or deficiencies may increase our expenses, adversely affect our 
financial position through the initiation, pendency or outcome of litigation or otherwise, or cause us to fail to meet our public financial 
reporting obligations.  

We have consummated three significant acquisitions since 2013 and in the future may continue to invest a substantial amount of 
capital in acquisitions. We continue to evaluate potential acquisition opportunities to support, strengthen and grow our business. There 
can be no assurance that we will be able to locate suitable acquisition candidates, acquire possible acquisition candidates, acquire such 
candidates on commercially reasonable terms, or integrate acquired businesses successfully in the future. In addition, any 
governmental review or investigation of our proposed acquisitions, such as by the Federal Trade Commission, may impede, limit or 
prevent us from proceeding with an acquisition. Future acquisitions may require us to incur additional debt and contingent liabilities, 
which may adversely affect our business, results of operations and financial condition. The process of integrating acquired businesses 
into our existing operations may result in operating, contract and supply chain difficulties, such as the failure to retain customers or 
management personnel. Such difficulties may divert significant financial, operational and managerial resources from our existing 
operations and make it more difficult to achieve our operating and strategic objectives.  

If we fail to properly manage our anticipated growth, our business could suffer.  

We may experience periods of rapid growth and expansion, which could place a significant strain on our personnel, information 
technology systems and other resources. In particular, the increase in our direct sales force requires significant management and other 
supporting resources. Any failure by us to manage our growth effectively could have an adverse effect on our ability to achieve our 
development and commercialization goals. 

To achieve our revenue goals, we must successfully increase production output as required by customer demand. In the future, 

we may experience difficulties in increasing production, including problems with production yields and quality control, component 

20 

  
 
supply and shortages of qualified personnel. These problems could result in delays in product availability and increases in expenses. 
Any such delay or increased expense could adversely affect our ability to generate revenues. 

Future growth will also impose significant added responsibilities on management, including the need to identify, recruit, train 

and integrate additional employees. In addition, rapid and significant growth will place a strain on our administrative and operational 
infrastructure. In order to manage our operations and growth, we will need to continue to improve our operational and management 
controls, reporting and information technology systems and financial internal control procedures. If we are unable to manage our 
growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. 

We depend on our officers and other skilled and experienced personnel to operate our business effectively. If we are not able 
to retain our current employees or recruit additional qualified personnel, our business will suffer and our future revenue and 
profitability will be impaired.  

We are highly dependent on the skills and experience of our President and Chief Executive Officer, Michael H. Carrel, and 

certain other officers and key employees. We do not have any insurance in the event of the death or disability of key personnel. Our 
officers and key employees, with the exception of our President and Chief Executive Officer, do not have employment agreements, 
and they may terminate their employment and work elsewhere without notice and without cause or good reason. Currently we have 
non-compete agreements with our officers and other employees. Due to the specialized knowledge of each of our officers with respect 
to our products and our operations and the limited pool of people with relevant experience in the medical device field, the loss of 
service of one or more of these individuals could significantly affect our ability to operate and manage our business. The 
announcement of the loss of one or more of our key personnel could negatively affect our stock price.  

We depend on our scientific and technical personnel for successful product development and innovation, which are critical to 

the success of our business. In addition, to succeed in the implementation of our business strategy, our management team must rapidly 
execute our sales strategy, obtain expanded FDA clearances and approvals, achieve market acceptance for our products and further 
develop products, while managing anticipated growth by implementing effective planning, manufacturing and operating processes. 
Managing this growth will require us to attract and retain additional management and technical personnel. We rely primarily on direct 
sales employees to sell our products in the United States and failure to adequately train them in the use and benefits of our products 
will prevent us from achieving our market share and revenue growth goals. We have key relationships with physicians that involve 
procedure, product, market and clinical development. If any of these physicians end their relationship with us, our business could be 
negatively impacted. We cannot assure you that we will be able to attract and retain the personnel and physician relationships 
necessary to grow and expand our business and operations. If we fail to identify, attract, retain and motivate these highly skilled 
personnel and physicians, we may be unable to continue our development and sales activities.  

Disruptions of critical information systems or material breaches in the security of our systems could harm our business, 
customer relations and financial condition. 

In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary 
business information and that of our customers, suppliers and business partners, and personally identifiable information of our 
customers and employees in our data centers and on our networks. The secure processing, maintenance and transmission of this 
information is critical to our operations and business strategy. Despite our security measures, our information technology and 
infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. Any such 
breach could compromise our networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any 
such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the 
privacy of personal information, regulatory penalties, disrupt our operations and the services we provide to customers, and damage our 
reputation and cause a loss of confidence in our products and services, which could adversely affect our business, operating margins, 
revenues and competitive position.  

We also rely in part on information technology to store information, interface with customers, maintain financial accuracy, 
secure our data and accurately produce our financial statements. If our information technology systems do not effectively and securely 
collect, store, process and report relevant data for the operation of our business, whether due to equipment malfunction or constraints, 
software deficiencies, human error or cyber incident, our ability to effectively plan, forecast and execute our business plan and comply 
with applicable laws and regulations would be materially impaired. Any such impairment could have a material adverse effect on our 
results of operations, financial condition and the timeliness with which we report our operating results. 

Our insurance may not cover our indemnification obligations and other liabilities associated with our operations.  

We maintain insurance designed to provide coverage for ordinary risks associated with our operations and our ordinary 
indemnification obligations, which we believe to be customary for our industry. The coverage provided by such insurance may not be 
adequate for claims we may make or may be contested by our insurance carriers. If our insurance is not adequate or available to pay 
liabilities associated with our operations, or if we are unable to purchase adequate insurance at reasonable rates in the future, our 
business, financial condition, results of operations or cash flows may be materially adversely impacted. 

21 

  
 
Legal & Compliance Risks 

We spend considerable time and money complying with federal, state and foreign regulations in addition to FDA regulations, 
and, if we are unable to fully comply with such regulations, we could face substantial penalties.  

We are subject to extensive regulation by the federal government and foreign countries in which we conduct business. The laws 

that affect our ability to operate our business in addition to the FDCA and FDA regulations include, but are not limited to, the 
following:  
• 

the Federal Anti-Kickback Statute, which prohibits persons from knowingly and willfully soliciting, offering, receiving or 
providing remuneration, directly or indirectly, in cash or in kind, to induce either the referral of an individual, or furnishing or 
arranging for a good or service, for which payment may be made under federal healthcare programs such as the Medicare and 
Medicaid Programs;  

• 

the Federal False Claims Act, which prohibits submitting a false claim or causing the submission of a false claim to the 
government;  

•  Medicare laws and regulations that prescribe the requirements for coverage and payment, including the amount of such payment, 

and laws prohibiting false claims for reimbursement under Medicare and Medicaid;  

• 

• 

• 

• 

• 
• 

state consumer protection, fraud and business practice laws, including the California Consumer Privacy Act (“CCPA”), which 
became effective on January 1, 2020, which among other things, requires new disclosures to California consumers and provides 
consumers new abilities to opt out of certain sales of personal information; 

state laws that prohibit the practice of medicine by non-doctors and by doctors not licensed in a particular state, and fee-splitting 
arrangements between doctors and non-doctors, as well as state law equivalents to the Anti-Kickback Statute and the Stark Law, 
which may not be limited to government-reimbursed items;  

federal and state healthcare fraud and abuse laws or laws protecting the privacy of patient medical information, including the 
Health Insurance Portability and Accountability Act (HIPAA) which protects medical records and other personal health 
information by limiting their use and disclosure, giving individuals the right to access, amend and seek accounting reasonably 
necessary to accomplish the intended purpose;  

laws and regulations with respect to the collection, use, disclosure, transfer, and storage of personal data that we may collect from 
our employees, consultants or in conjunction with clinical trials such as the General Data Protection Regulation in the European 
Union; 

the Federal Trade Commission Act and similar laws regulating advertising and consumer protection; and  

similar and other regulations outside the United States.  

Healthcare fraud and abuse regulations are complex, and even minor, inadvertent irregularities can potentially give rise to 

claims that a law has been violated. Any violations of these laws could result in a material adverse effect on our business, financial 
condition and results of operations. If there is a change in law, regulation or administrative or judicial interpretations, we may have to 
change our business practices or our existing business practices could be challenged as unlawful, which could have a material adverse 
effect on our business, financial condition and results of operations.  

Our manufacturing operations and research and development activities involve the use of biological materials and hazardous 

substances and are subject to a variety of federal, state and local environmental laws and regulations relating to the storage, use, 
discharge, disposal, remediation of and human exposure to hazardous substances. Our research and development and manufacturing 
operations may produce biological waste materials, such as animal tissues and certain chemical waste. These operations are permitted 
by regulatory authorities, and the resultant waste materials are disposed of in compliance with environmental laws and regulations. 
Compliance with these laws and regulations may be expensive, and non-compliance could result in substantial liabilities. In addition, 
we cannot eliminate the risk of accidental contamination or injury to third parties from the use, storage, handling or disposal of these 
materials. In the event of contamination or injury, we could be held liable for any resulting damages, and any liability could exceed 
any applicable insurance coverage we may have. Our manufacturing operations may result in the release, discharge, emission or 
disposal of hazardous substances that could cause us to incur substantial liabilities, including costs for investigation and remediation.  

If our past or present operations are found to be in violation of any of the laws described above or the other governmental 
regulations to which we, our distributors or our customers are subject, we may be subject to the applicable penalty associated with the 
violation, including civil and criminal penalties, damages, fines, exclusion from Medicare, Medicaid and other government programs 
and the curtailment or restructuring of our operations. If we are required to obtain permits or licensure under these laws that we do not 
already possess, we may become subject to substantial additional regulation or incur significant expense. Any penalties, damages, 
fines, curtailment or restructuring of our operations would adversely affect our ability to operate our business and our financial results. 
The risk of our being found in violation of these laws is increased by the fact that many of them have not been fully or clearly 
interpreted by the regulatory authorities or the courts, and their provisions are subject to a variety of interpretations and additional 
legal or regulatory change. Any action against us for violation of these laws, 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 damage our reputation.  

22 

  
 
If we fail to comply with the extensive FDA regulations relating to our business, we may be subject to fines, injunctions and 
penalties, and our ability to commercially distribute and promote our products may be hurt.  

Our products are classified by FDA as medical devices and, as such, are subject to extensive regulation by FDA and numerous 
other federal, state and foreign governmental authorities. FDA regulations, guidance, notices and other issuances specific to medical 
devices are broad and regulate numerous aspects of our business. Compliance with FDA, state and other regulations can be complex, 
expensive and time-consuming. FDA and other authorities have broad enforcement powers. Furthermore, changes in the applicable 
governmental regulations could prevent further commercialization of our products and technologies and could materially harm our 
business.  

If a serious failure to comply with applicable regulatory requirements was determined, it could result in enforcement action by 

repair, replacement, refunds, recall or seizure of our products;  

operating restrictions, partial suspension or total shutdown of production;  

FDA or other state or federal agencies, including the DOJ, which may include any of the following sanctions, among others:  
•  warning letters, fines, injunctions, consent decrees and civil penalties;  
• 
• 
• 
• 
•  withdrawing 510(k) clearance or PMAs that have already been granted; and  
• 

suspension or termination of our clinical trials; 

criminal prosecution.  

refusing or delaying our pending requests for 510(k) clearance or PMAs, new intended uses or modifications to existing products;  

If any of these events were to occur, we could lose customers and our production, product sales, business, results of operations 

and financial condition would be harmed.  

We are also subject to medical device reporting regulations that require us to file reports with FDA if our products may have 
caused or contributed to a death or serious injury or, in the event of product malfunction, that if such malfunction were to recur, would 
likely cause or contribute to a death or serious injury. There have been incidents, including patient deaths, which have occurred during 
or following procedures using our products that we have not reported to FDA because we determined that our products did not 
malfunction and did not cause or contribute to the outcomes in these incidents. If FDA disagrees with us, however, and determines 
that we should have submitted reports for these adverse events, we could be subject to significant regulatory fines or other penalties. 
In addition, the number of medical device reports we make, or the magnitude of the problems reported, could cause us or FDA to 
terminate or modify our clinical trials or recall or cease the sale of our products, and could hurt commercial acceptance of our products 
and harm our reputation with customers.  

Unless and until we obtain additional FDA approval for our products, we will not be able to promote most of them to treat 
Afib or to prevent stroke, and our ability to maintain and grow our business could be harmed. We may be subject to fines, 
penalties, injunctions and other sanctions if we are deemed to be promoting the use of our products for unapproved, or off-
label, uses.  

Our business and future growth depend on the continued use of our products for the treatment of Afib or prevention of stroke. 
Unless the products are approved or cleared by FDA specifically for the treatment of Afib or prevention of stroke, we may not make 
claims about the safety or effectiveness of our products for such uses. In order to obtain additional FDA approvals to promote our 
products for the treatment of Afib or reduction in stroke risk, we will need to demonstrate in clinical trials that our products are safe 
and effective for such use. Development of sufficient and appropriate clinical protocols to demonstrate quality, safety and efficacy 
may be required and we may not adequately develop such protocols to support approval. We cannot assure you that any of our clinical 
trials will be completed in a timely manner or successfully or that the results obtained will be acceptable to FDA. We, FDA or the IRB 
may suspend a clinical trial at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated 
benefits. 

These limitations present a material risk that FDA or other federal or state law enforcement authorities could determine that the 

nature and scope of our sales, marketing and/or support activities, though designed to comply with all FDA requirements, constitute 
the promotion of our products for an unapproved use in violation of the FDCA. We also face the risk that FDA or other governmental 
authorities might pursue enforcement based on past activities that we have discontinued or changed, including sales activities, 
arrangements with institutions and doctors, educational and training programs and other activities. Investigations concerning the 
promotion of unapproved uses and related issues, are typically expensive, disruptive and burdensome and generate negative publicity. 
If our promotional activities are found to be in violation of the law, we may face significant fines and penalties and may be required to 
substantially change our sales, promotion, grant and educational activities. There is also a possibility that we could be enjoined from 
selling some or all of our products for any unapproved use.  

Although our Isolator Synergy System received FDA approval for the treatment of some forms of Afib in certain procedures, we 

have not received FDA clearance or approval to promote our other products for the treatment of Afib or the prevention of stroke. 
Unless and until we obtain FDA clearance or approval for the use of our other products to treat Afib or prevent stroke, we, and others 

23 

  
 
acting on our behalf, may not claim in the U.S. that such products are safe and effective for such uses or otherwise promote them for 
such uses. Similar restrictions exist outside of the U.S. There is no assurance that future clearances or approvals of our products will 
be granted or that current or future clearances or approvals will not be withdrawn. Failure to obtain a clearance or approval or loss of 
an existing clearance or approval, could hurt our ability to maintain and grow our business. 

Modifications to our products may require new clearances or approvals or may require us to cease promoting or to recall the 
modified products until such clearances or approvals are obtained and FDA may not agree with our conclusions regarding 
whether new clearances or approvals were required. 

Any modification to a 510(k)-cleared device that would constitute a change in its intended use, design or manufacture could 
require a new or supplemental 510(k) clearance or, possibly, submission and FDA approval of a PMA application. FDA requires every 
medical device company to make the determination as to whether a 510(k) must be filed, but FDA may review any medical device 
company’s decision. We have made modifications to our products and concluded that such modifications did not require us to submit 
a new or supplemental 510(k). FDA may not agree with our decisions regarding whether submissions were required.  

If FDA were to disagree with us and require us to submit a 510(k), PMA or a PMA supplement for then-existing modifications, 
we could be required to cease promoting or to recall the modified product until we obtain clearance or approval. In addition, we could 
be subject to significant regulatory fines or other penalties. Furthermore, our products could be subject to recall if FDA determines, for 
any reason, that our products are not safe or effective or that appropriate regulatory submissions were not made. Delays in receipt or 
failure to receive clearances or approvals, the loss of previously received clearances or approvals or the failure to comply with existing 
or future regulatory requirements could reduce our sales, profitability and future growth prospects.  

If we or our third-party vendors fail to comply with extensive FDA regulations relating to the manufacturing of our products 
or any component part, we may be subject to fines, injunctions and penalties, and our ability to commercially distribute and 
sell our products may be hurt.  

Our manufacturing facilities and the manufacturing facilities of any of our third-party component manufacturers, critical 

suppliers or third-party sterilization facility are required to comply with FDA’s QSR, which sets forth minimum standards for the 
procedures, execution and documentation of the design, testing, production, control, quality assurance, labeling, packaging, 
sterilization, storage and shipping of the products we sell. FDA may evaluate our compliance with the QSR, among other ways, 
through periodic announced or unannounced inspections which could disrupt our operations and interrupt our manufacturing. If in 
conducting an inspection of our manufacturing facilities or the manufacturing facilities of any of our third-party component 
manufacturers, critical suppliers or third-party sterilization facilities, an FDA investigator observes conditions or practices believed to 
violate the QSR, the investigator may document their observations on a Form FDA-483 that is issued at the conclusion of the 
inspection. A manufacturer that receives an FDA-483 may respond in writing and explain any corrective actions taken in response to 
the inspectional observations. FDA will typically review the facility’s written response and may re-inspect to determine the facility’s 
compliance with the QSR and other applicable regulatory requirements. Failure to take adequate and timely corrective actions to 
remedy objectionable conditions listed on an FDA-483 could result in FDA taking administrative or enforcement actions. Among 
these may be FDA’s issuance of a Warning Letter to a manufacturer, which informs the manufacturer that FDA considers the 
observed violations to be of “regulatory significance” that, if not corrected, could result in further enforcement action. FDA 
enforcement actions, which include seizure, injunction and criminal prosecution, could result in total or partial suspension of a 
facility’s production and/or distribution, product recalls, fines, suspension of FDA’s review of product applications and FDA’s 
issuance of adverse publicity. Thus, an adverse inspection could force a shutdown of our manufacturing operations or a recall of our 
products. Adverse inspections could also delay FDA approval of our products and could have an adverse effect on our production, 
sales and financial condition.  

We and any of our third-party vendors may also encounter other problems during manufacturing including failure to follow 

specific protocols and procedures, equipment malfunction and environmental factors, any of which could delay or impede our ability 
to meet demand. The manufacture of our product also subjects us to risks that could harm our business, including problems relating to 
the sterilization of our products or facilities and errors in manufacturing components that could negatively affect the efficacy or safety 
of our products or cause delays in shipment of our products. Any interruption or delay in the manufacture of the product or any of its 
components could impair our ability to meet the demand of our customers and cause them to cancel orders or switch to competitive 
products and could, therefore, have a material adverse effect on our business, financial condition and results of operations.  

We are currently under investigation by the United States Department of Justice, and any adverse finding, allegation, or 
exercise of enforcement or regulatory discretion by the DOJ could materially and adversely affect our business, financial 
condition or results of operations.  

As previously disclosed, on December 11, 2017, the Company received a Civil Investigative Demand (CID) from the U.S. 

Department of Justice (DOJ) stating that it is investigating the Company to determine whether the Company has violated the False 
Claims Act, relating to the promotion of certain medical devices related to the treatment of atrial fibrillation for off-label use and 
submitted or caused to be submitted false claims to certain federal and state health care programs for medically unnecessary healthcare 
services related to the treatment of Afib. The CID covers the period from January 2010 to December 2017 and requires the production 
of documents and answers to written interrogatories. The Company had no knowledge of the investigation prior to receipt of the CID. 
24 

  
 
The Company maintains rigorous policies and procedures to promote compliance with the False Claims Act and other applicable 
regulatory requirements. The Company provided the DOJ with documents and answers to the written interrogatories and is 
cooperating with the investigation. However, the Company cannot predict when the investigation will be resolved, the outcome of the 
investigation or its potential impact on the Company. While the Company believes its practices are lawful, there can be no assurance 
that the DOJ’s ongoing investigation or future exercise of its enforcement, regulatory, discretionary or other powers will not result in 
findings or alleged violations of federal laws that could lead to enforcement actions, proceedings or litigation and the imposition of 
damages, fines, penalties, restitution, other monetary liabilities, sanctions, settlements or changes to the Company’s business practices 
or operations that could have a material adverse effect on the Company’s business, financial condition or results of operations or 
eliminate altogether the Company’s ability to operate its business or on terms substantially similar to those on which it currently 
operates. 

The use of products we sell may result in injuries or other adverse events that lead to product liability suits, which could be 
costly to our business or our customers’ businesses. 

The use of our products may result in a variety of serious complications, including damage to the heart, internal bleeding, death 
or other adverse events. Serious complications are commonly encountered in connection with surgical procedures. If products we sell 
are defectively designed, manufactured or labeled, contain inadequate warnings, contain defective components, are misused or are 
associated with serious injuries or deaths, we may become subject to costly litigation by our customers or their patients. We carry 
product liability insurance that is limited in scope and amount and may not be adequate to fully protect us against product liability 
claims. We could be required to pay damages that exceed our insurance coverage, and such amounts could be significant. Any product 
liability claim, with or without merit, could also result in an increase in our insurance rates or our inability to secure coverage on 
reasonable terms, if at all. Even in the absence of a claim, our insurance rates may rise in the future. Any product liability claim, even 
a meritless or unsuccessful one, would be time-consuming and expensive to defend and could result in the diversion of our 
management’s attention from our business and result in adverse publicity, withdrawal of clinical trial participants, injury to our 
reputation and loss of revenue. Any of these events could negatively affect our financial condition. 

Our intellectual property rights may not provide meaningful commercial protection for our products, which could enable 
third parties to use our technology or methods, or very similar technology or methods, and could reduce our ability to 
compete.  

Our success depends significantly on our ability to protect our proprietary rights to the technologies used in our products. We 

rely on patent protection, as well as a combination of copyright, trade secret and trademark laws and nondisclosure, confidentiality and 
other contractual restrictions to protect our proprietary technology. However, these legal means afford only limited protection and may 
not adequately protect our rights or permit us to gain or keep any competitive advantage. Our patent applications may not issue as 
patents at all or in a form that will be advantageous to us. Our issued patents and those that may be issued in the future may be 
challenged, invalidated or circumvented, which could limit our ability to stop competitors from marketing related products.  

Although we have taken steps to protect our intellectual property and proprietary technology, we cannot assure you that third 
parties will not be able to design around our patents or, if they do infringe upon our technology, that we will be successful in or will 
have sufficient resources to pursue a claim of infringement against those third parties. We believe that third parties may have 
developed or are developing products that could infringe upon our patent rights. Any pursuit of an infringement claim by us may 
involve substantial expense or diversion of management attention. In addition, although we have generally entered into confidentiality 
agreements and intellectual property assignment agreements with our employees, consultants, investigators and advisors, such 
agreements may be breached, may not be enforceable or may not provide meaningful protection for our trade secrets or other 
proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements. Additionally, as is common 
in the medical device industry, some of these individuals were previously employed at other medical equipment or biotechnology 
companies, including our competitors. Although no claims are currently pending against us, we may be subject to claims that these 
individuals have used or disclosed trade secrets or other proprietary information of their former employers.  

The laws of foreign countries may not protect our intellectual property rights to the same extent as the laws of the United States. 
Foreign countries generally do not allow patents to cover methods for performing surgical procedures. If our intellectual property does 
not provide significant protection against foreign or domestic competition, our competitors could compete more directly with us, 
which could result in a decrease in our revenue and market share. All of these factors may harm our competitive position. 

The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other 
intellectual property rights and any litigation or claim against us may cause us to incur substantial costs, could place a 
significant strain on our financial resources, divert the attention of management from our business and harm our reputation. 

Despite measures taken to protect our intellectual property, unauthorized parties might copy aspects of our products or obtain 

and use information that we regard as proprietary. Whether a product infringes a patent involves complex legal and factual issues, the 
determination of which is often uncertain. Any patent dispute, even one without merit or an unsuccessful one, would be time-
consuming and expensive to defend and could result in the diversion of our management’s attention from our business and result in 
adverse publicity, the disruption of development and marketing efforts, injury to our reputation and loss of revenue. Litigation also 

25 

  
 
puts our patent applications at risk of being rejected and our patents at risk of being invalidated or interpreted narrowly and may 
provoke third parties to assert claims against us. Any of these events could negatively affect our financial condition. 

In the event of a patent dispute, if a third party’s patents were upheld as valid and enforceable and we were found to be 
infringing, or found to be inducing infringement by others, we could be prevented from selling our products unless we were able to 
obtain a license to use technology or ideas covered by such patent or are able to redesign our system to avoid infringement, or we may 
be ordered to pay substantial damages to the patent holders. A license may not be available at all or on terms acceptable to us, and we 
may not be able to redesign our products to avoid any infringement. Modification of our products or development of new products 
could require us to conduct additional clinical trials and to revise our filings with FDA and other regulatory bodies, which would be 
time-consuming and expensive. If we are not successful in obtaining a license or redesigning our products, we may be unable to sell 
our products and our business could suffer. 

We sell our products outside of the United States, and we are subject to various regulatory and other risks relating to 
international operations, which could harm our revenue and profitability. 

Doing business outside of the United States exposes us to risks distinct from those we face in our domestic operations. For 

example, our operations outside of the United States are subject to different regulatory requirements in each jurisdiction where we 
operate or have sales. Our failure, or the failure of our distributors, to comply with current or future foreign regulatory requirements, 
or the assertion by foreign authorities that we or our distributors have failed to comply, could result in adverse consequences, 
including enforcement actions, fines and penalties, recalls, cessation of sales, civil and criminal prosecution, and the consequences 
could be disproportionate to the relative contribution of our international operations to our results of operations. Moreover, if political 
or economic conditions deteriorate in these countries, or if any of these countries are affected by a natural disaster or other 
catastrophe, our ability to conduct our international operations or collect on international accounts receivable could be limited and our 
costs could be increased, which could negatively affect our operating results. Engaging in business outside of the United States 
inherently involves a number of other difficulties and risks, including, but not limited to: 
• 
• 
• 
• 
• 

consequences arising from natural disasters and other similar catastrophes, such as hurricanes, tornados, earthquakes, floods and 
tsunamis;  

difficulties in enforcing agreements and collecting receivables through certain foreign legal systems;  

pricing pressure that we may experience internationally;  

export restrictions and controls relating to technology;  

political and economic instability;  

• 
• 
• 
• 

• 

potentially adverse tax consequences, tariffs and other trade barriers;  

the need to hire additional personnel to promote our products outside of the United States;  

international terrorism and anti-American sentiment;  

fluctuations in exchange rates for future sales denominated in foreign currency, which represent a portion of our sales outside of 
the United States; and  

difficulty in obtaining and enforcing intellectual property rights.  

Our exposure to each of these risks may increase our costs and require significant management attention. We cannot assure you 

that one or more of these factors will not harm our business. 

Due to the global nature of our business, we may be exposed to liabilities under the Foreign Corrupt Practices Act and various 
other anti-corruption laws, and any allegation or determination that we violated these laws could have a material adverse 
effect on our business.  

Our business practices in foreign countries must comply with anti-corruption laws, including the Foreign Corrupt Practices Act 
(FCPA), the UK Anti-Bribery Act of 2010 and other U.S. and foreign anti-corruption laws, which prohibit companies from engaging 
in bribery including corruptly or improperly offering, promising, or providing money or anything else of value to foreign officials and 
certain other recipients. In addition, the FCPA imposes certain books, records and accounting control obligations on public companies 
and other issuers. We operate in parts of the world in which corruption can be common and compliance with anti-bribery laws may 
conflict with local customs and practices. Our global operations face the risk of unauthorized payments or offers being made by 
employees, consultants, sales agents and other business partners outside of our control or without our authorization.  

We have a compliance program in place designed to reduce the likelihood of potential violations of the FCPA and other U.S. 

and foreign anti-bribery and anti-corruption laws. It is our policy to implement safeguards (including mandatory training) to prohibit 
these practices by our employees and business partners with respect to our operations. However, irrespective of these safeguards, or as 
a result of monitoring compliance with such safeguards, it is possible that we or certain other parties may discover or receive 
information at some point that certain employees, consultants, sales agents, or other business partners may have engaged in corrupt 
conduct for which we might be held responsible. 

26 

  
 
Violations of the FCPA or other foreign anti-corruption laws may result in restatements of, or irregularities in, our financial 

statements as well as severe criminal or civil sanctions, and we may be subject to other liabilities, which could negatively affect our 
business, operating results and financial condition. In some cases, companies that violate the FCPA may be debarred by the U.S. 
government and/or lose their U.S. export privileges. Changes in anti-corruption laws or enforcement priorities could also result in 
increased compliance requirements and related costs which could adversely affect our business, financial condition and results of 
operations. In addition, the U.S. or other governments may seek to hold us liable for successor liability FCPA violations or violations 
of other anti-corruption laws committed by companies in which we invest or that we acquired or will acquire.  

Compliance with developing European Union medical device regulations may limit our ability to maintain sales of our 
products in European markets or to introduce new products into European markets.  

Many foreign countries where we market or may market our products have regulatory bodies and restrictions similar to those of 

FDA. International sales are subject to foreign government regulation, the requirements of which vary substantially from country to 
country. The time required to obtain approval by a foreign country may be longer or shorter than that required for FDA clearance and 
the requirements may differ. In particular, marketing of medical devices in the EU is subject to compliance with the Medical Device 
Directive 93/92/EEC (MDD). A medical device may be placed on the market within the EU only if it conforms to certain “essential 
requirements” and bears the CE Mark. The most fundamental and essential requirement is that a medical device must be designed and 
manufactured in such a way that it will not compromise the clinical condition or safety of patients, or the safety and health of users 
and others. In addition, the device must achieve the essential performance intended by the manufacturer and be designed, 
manufactured and packaged in a suitable manner. 

In May 2017, the EU adopted a new Medical Device Regulation (EU) 2017/745 (MDR), which will repeal and replace the MDD 
effective May 26, 2021. The MDR clearly envisages, among other things, stricter controls of medical devices, including strengthening 
of the conformity assessment procedures, increased expectations with respect to clinical data for devices and pre-market regulatory 
review of high-risk devices. The MDR also envisages greater control over notified bodies and their standards, increased transparency, 
more robust device vigilance requirements and clarification of the rules for clinical investigations. Under transitional provisions, 
medical devices with notified body certificates issued under the MDD prior to May 26, 2021 may continue to be placed on the market 
for the remaining validity of the certificate, until May 26, 2024 at the latest. After the expiry of any applicable transitional period, only 
devices that have been CE marked under the MDR may be placed on the market in the EU. If we fail to comply with the new MDR, 
we may not be able to continue to sell existing products in the EU or introduce new products for sale in the EU, either of which could 
materially harm our results of operations and financial condition. 

The United Kingdom’s withdrawal from the European Union (EU) may have a negative effect on global economic conditions, 
financial markets and our business.  

The United Kingdom (U.K.) left the EU on January 31, 2020. The withdrawal (known as “Brexit”) has created significant 
uncertainty about the future relationship between the United Kingdom and the EU, including with respect to the laws and regulations 
that will apply as the United Kingdom determines which EU laws to replace or replicate to facilitate the withdrawal. From a regulatory 
perspective, the United Kingdom’s withdrawal gives rise to significant complexity and risks. Since the medical device regulatory 
framework in the United Kingdom is derived from the EU Medical Devices Directive, the United Kingdom’s withdrawal could 
materially impact the continued marketing of EU medical devices in the United Kingdom.  

The U.K. and the EU reached a free trade agreement on December 24, 2020, which included regulatory and customs 

cooperation mechanisms, as well as provisions supporting open and fair competition. Under the trade agreement, the U.K. is free to set 
its own trade policy and can negotiate with other countries that do not currently have free trade deals with the EU.  Although the full 
impact of the trade agreement is uncertain, it is possible that the recent changes to the trading relationship between the U.K. and the 
EU due to the trade agreement could result in increased cost of goods imported into and exported from the U.K., which may decrease 
the profitability of our operations. Additional currency volatility could drive a weaker British pound, which could increase the cost of 
goods imported into the U.K. and may decrease the profitability of our operations. A weaker British pound versus the U.S. dollar may 
also cause local currency results of our operations to be translated into fewer U.S. dollars during a reporting period.  

The U.K.’s withdrawal from the EU has resulted in significant changes to the movement of goods and personnel between the 
United Kingdom and the remaining member states of the EU. Products will be subject to additional inspections and documentation 
checks, leading to possible delays at ports of entry and departure. The withdrawal could also adversely impact the operations of our 
vendors and of our other partners. Additionally, we face new regulations regarding trade, aviation, tax, security and employees, among 
others, in the United Kingdom. Compliance with such regulations could be costly, negatively impacting our business, results of 
operations and financial condition. Brexit could also adversely affect European and worldwide economic and market conditions and 
could contribute to instability in global financial markets. 

Given the lack of precedent, it is unclear what financial, trade, regulatory and legal implications the trade agreement will have 
on our business; however, Brexit and its related effects could potentially have an adverse impact on our financial position and results 
of operations. Our management team has evaluated a range of possible outcomes, identified areas of concerns, and implemented 
strategies to help mitigate these concerns. It is possible that these strategies may not be adequate to mitigate any adverse impacts of 
Brexit, and that these impacts could further adversely affect our business and results of operations. 

27 

  
 
Financial Risks 

Our quarterly financial results are likely to fluctuate significantly because our sales prospects are uncertain.  

Due to current worldwide economic conditions, natural disasters and other factors discussed in this “Risk Factors” section which 

may impact our sales results, our quarterly operating results are difficult to predict and may fluctuate significantly from quarter to 
quarter or from prior year to current year periods. These fluctuations may also affect our annual operating results and may cause those 
results to fluctuate unexpectedly from year to year. 

We have a history of net losses, and we may never become profitable.  

We have incurred net losses each year since our inception, including, most recently, net losses of $48,155 in 2020, $35,194 in 

2019 and $21,137 in 2018. As of December 31, 2020, we had an accumulated deficit of $330,352. 

Our net losses have resulted principally from costs and expenses relating to sales, training and promotional efforts, research and 

development, clinical trials, seeking regulatory clearances and approvals and general operating expenses. We expect to continue to 
incur substantial expenditures and to potentially incur additional operating losses in the future as we further develop and 
commercialize our products. If sales of our products do not continue to grow as we anticipate, we will not be able to achieve 
profitability. Our expansion efforts may prove to be more expensive than we currently anticipate, and we may not succeed in 
increasing our revenue sufficiently to offset these higher expenses. Our losses have had, and are expected to continue to have, an 
adverse impact on our working capital, total assets and accumulated deficit. 

Our federal tax net operating loss (NOL) and general business credit carryforwards generated or acquired may expire or will 
be limited because we experienced an ownership change of more than 50 percent, which could result in greater future income 
tax expense and adversely impact future cash flows.  

On June 30, 2001, we experienced an ownership change as defined by Section 382 of the Internal Revenue Code of 1986. 
Section 382 imposes limitations (Section 382 limitation) on a company’s ability to use net operating loss and general business credit 
carryforwards if a company experiences a more-than-50-percent ownership change over a three-year testing period. Additionally, in 
connection with acquisitions, certain acquired NOLs are also subject to Section 382 limitation. The Section 382 limitations could limit 
the availability of our net operating loss and general business credit carryforwards to offset any future taxable income, which may 
increase our future income tax expense and adversely impact future cash flows. Net operating losses generated prior to 2018 are also 
subject to expiration under current IRS regulations. We have total federal income tax net operating loss carryforwards that have begun 
to expire in 2020 and research and development credit carryforwards that will begin to expire in 2022. We have available net 
operating loss and research and development credit carryforwards, subject to expiration of $339,699 and $9,365 as of December 31, 
2020.  

Our effective income tax rate may fluctuate, which may adversely affect our operations, earnings and earnings per share.  

Our effective income tax rate is influenced by our projected profitability in the various taxing jurisdictions in which we operate. 

The global nature of our business increases our tax risks. In addition, revenue authorities in many of the jurisdictions in which we 
operate are known to have become more active in their tax collection activities. Changes in the distribution of profits and losses 
among taxing jurisdictions may have a significant impact on our effective income tax rate, which in turn could have an adverse effect 
on our net income and earnings per share. The application of tax laws in various taxing jurisdictions, including the United States, is 
subject to interpretation, and tax authorities in various jurisdictions may have diverging and sometimes conflicting interpretations of 
the application of tax laws. Changes in tax laws or tax rulings, in the United States or other tax jurisdictions in which we operate, 
could materially impact our effective tax rate.  

• 

• 

• 
• 
• 
• 

Factors that may affect our effective income tax rate include, but are not limited to:  

the requirement to exclude from our quarterly worldwide effective income tax calculations losses in jurisdictions where no 
income tax benefit can be recognized; 

actual and projected full year pre-tax income, including differences between actual and anticipated income before taxes in various 
jurisdictions; 

changes in tax laws, or in the interpretation or application of tax laws, in various taxing jurisdictions; 

changes in the relative mix and staffing levels in various tax jurisdictions; 

audits or other challenges by taxing authorities; and 

the establishment of valuation allowances against a portion or all of certain deferred income tax assets if we determined that it is 
more likely than not that future income tax benefits will not be realized. 

These changes may cause fluctuations in our effective income tax rate that could adversely affect our results of operations and 

cause fluctuations in our earnings and earnings per share.  

28 

  
 
Governmental authorities may question our intercompany transfer pricing policies or change their laws in a manner that 
could increase our effective tax rate or otherwise harm our business.  

As a U.S. company doing business in international markets through subsidiaries, we are subject to foreign tax and intercompany 
pricing laws, including those relating to the flow of funds between the parent and subsidiaries. Tax authorities in the United States and 
in foreign markets closely monitor our corporate structure and how we account for intercompany fund transfers. If tax authorities 
challenge our corporate structure, transfer pricing mechanisms or intercompany transfers, our operations may be negatively impacted 
and our effective tax rate may increase. Tax rates vary from country to country and if regulators determine that our profits in one 
jurisdiction should be increased, we might not be able to fully offset any associated increase in tax expense in the other jurisdiction, 
which would increase our effective tax rate. Additionally, the Organization for Economic Cooperation and Development, or OECD, 
has issued certain proposed guidelines regarding base erosion and profit sharing. As these guidelines are formally adopted by the 
OECD, it is possible that separate taxing jurisdictions may also adopt some form of these guidelines. In such case, we may need to 
change our approach to intercompany transfer pricing in order to maintain compliance under the new rules. Our effective tax rate may 
increase or decrease depending on the current location of global operations at the time of the change. Finally, we might not always be 
in compliance with all applicable customs, exchange control, Value Added Tax and transfer pricing laws despite our efforts to be 
aware of and to comply with such laws. In such case, we may need to adjust our operating procedures and our business could be 
adversely affected.  

If our goodwill or other intangible assets become impaired, it could materially reduce the value of our assets and reduce our 
net income or increase our net loss for the year in which the impairment occurs.  

As of December 31, 2020, we had $234,781 in goodwill related to acquisitions, which represents the purchase price we paid in 

excess of the fair value of the net assets we acquired. The Financial Accounting Standards Board’s (FASB) Accounting Standards 
Codification (ASC) 350, “Goodwill and Other Intangible Assets” requires that goodwill be tested for impairment at least annually 
(absent any impairment indicators). The testing includes comparing the fair value of each reporting unit with its carrying value. We 
may have future impairment adjustments to our recorded goodwill. Any finding that the value of our goodwill has been impaired 
would require us to record an impairment charge which could materially reduce the value of our assets and reduce our net income or 
increase our net loss for the year in which the impairment charge occurs and increase our accumulated deficit. 

In Process Research and Development (IPR&D) valued at $126,321 was recorded as an intangible asset in connection with the 

nContact and SentreHEART acquisitions. If we do not obtain the regulatory approvals that would confirm the technological feasibility 
of the respective IPR&D projects, or if the IPR&D projects are abandoned for any other reason, we could have an impairment 
adjustment of this asset that could require us to write off a portion or all of the recorded asset value. Additionally, and similar to 
goodwill, if the IPR&D asset is deemed to be impaired as a result of the estimated fair value being less than carrying value, we would 
be required to write off the impaired portion of the IPR&D asset. This would materially reduce the value of our assets and reduce our 
net income or increase our net loss for the year in which the write off occurs and increase our accumulated deficit.  

An inability to forecast future revenue or estimate life cycles of products may result in inventory-related charges that would 
negatively affect our gross margins and results of operations.  

To mitigate the risk of supply interruptions, we may choose to maintain additional inventory of our products or component 
parts. Managing our inventory levels is important to our cash position and results of operations and is challenging in the current 
economic environment. As we grow and expand our product offerings, managing our inventory levels becomes more difficult, 
particularly as we expand into new product areas and bring product enhancements to market. While we rely on our personnel and 
information technology systems for inventory management, our personnel and information technology systems may fail to adequately 
perform these functions or may experience an interruption. An excessive amount of inventory reduces our cash available for 
operations and may result in excess or obsolete materials. Conversely, inadequate inventory levels may make it difficult for us to meet 
customer product demand, resulting in decreased revenue. An inability to forecast future revenue or estimated life cycles of products 
may result in inventory-related charges that would negatively affect our gross margins and results of operations and increase our 
accumulated deficit. 

We are subject to credit risk from our accounts receivable related to our sales, which include sales to countries outside the 
United States that may experience economic turmoil. 

The majority of our accounts receivable arise from sales in the United States. However, we also have significant receivable 

balances from customers within the European Union and Asia. Our accounts receivable in the United States are primarily due from 
public and private hospitals. Our accounts receivable outside the United States are primarily due from public and private hospitals and 
from independent distributors. Our historical write-offs of accounts receivable have not been significant. We monitor the financial 
performance and credit worthiness of our customers so that we can properly assess and respond to changes in their credit profile. Our 
independent distributors operate in certain countries where economic conditions continue to present challenges to their businesses, 
and, thus, could place the amounts due to us at risk. These distributors are owed amounts from public hospitals that are funded by their 
governments. Adverse financial conditions in these countries may negatively affect the length of time that it will take us to collect 
associated accounts receivable or impact the likelihood of ultimate collection. 

29 

  
 
We may be unable to comply with the covenants of our Loan Agreement. 

Our Loan Agreement with Silicon Valley Bank (“SVB”) contains a minimum liquidity covenant and other customary terms and 
conditions. The occurrence of an event of default could result in an increase to the applicable interest rate by 3.0%, an acceleration of 
all obligations, an obligation to repay all obligations in full and a right by SVB to exercise all remedies available to them. If we are 
unable to pay those amounts, SVB could proceed against the collateral granted to it pursuant to the Loan Agreement, and we may in 
turn lose access to our current source of borrowing availability. 

Common Stock Risks  

We may fail to meet our publicly announced guidance or other expectations about our business and future operating results, 
which could cause a decline in our stock price. 

We provide financial guidance about our business and future operating results. In developing this guidance, our management 
makes certain assumptions and judgments about our future operating performance, including projected hiring of sales professionals, 
continued increase of our market share, and continued stability of the macro-economic environment in our key markets. Furthermore, 
analysts and investors may develop and publish their own projections of our business, which may form a consensus about our future 
performance. Our business results may vary significantly from such guidance or that consensus due to a number of factors, many of 
which are outside of our control, and which could adversely affect our operations and operating results. Furthermore, if we make 
downward revisions of our previously announced guidance, or if our publicly announced guidance of future operating results fails to 
meet expectations of securities analysts, investors, or other interested parties, the market price of our common stock could decline. 

Securities analysts may not continue, or additional securities analysts may not initiate, coverage for our common stock or may 
issue negative reports. This may have a negative impact on the market price of our common stock. 

Several securities analysts provide research coverage of our common stock. Some analysts have already published statements 

that do not portray our technology, products or procedures using our products in a positive light and others may do so in the future. If 
we are unable to educate those who publicize such reports about the benefits we believe our business provides, or if one or more of the 
analysts who elects to cover us downgrades our stock, our stock price would likely decline rapidly. If one or more of these analysts 
ceases coverage of our company, we could lose visibility in the market, which in turn could cause our stock price to decline. The 
trading market for our common stock may be affected in part by the research and reports that industry or financial analysts publish 
about us or our business. If sufficient securities analysts do not cover our common stock, the lack of research coverage may adversely 
affect the market price of our common stock. It may be difficult for companies such as ours, with smaller market capitalizations, to 
attract and maintain sufficient independent financial analysts that will cover our common stock. This could have a negative effect on 
the market price of our stock. 

The price and trading volume of our common stock may experience extreme fluctuations and our stockholders could lose some 
or all of their investment.  

Because we operate within the medical device segment of the healthcare industry, our stock price is likely to be volatile. The 

market price of our common stock may have and has had a history of substantial fluctuation due to a variety of factors, including, but 
not limited to those risk factors described in the “Risk Factors” section herein. These factors, some of which are not within our 
control, may cause the price of our stock to fluctuate substantially. We believe the quarterly and annual comparisons of our financial 
results are not necessarily meaningful and should not be relied upon as an indication of our future performance.  

The market prices of the securities of medical device companies, particularly companies like ours without consistent revenue 

and earnings, have been highly volatile and are likely to remain highly volatile in the future. This volatility has often been unrelated to 
the operating performance of these particular companies. In the past, companies that experience volatility in the market price of their 
securities have often faced securities class action litigation. Whether or not meritorious, litigation brought against us could result in 
substantial costs, divert our management’s attention and resources and harm our ability to grow our business.  

The sale of material amounts of common stock could encourage short sales by third parties and depress the price of our 
common stock. As a result, our stockholders may lose all or part of their investment. 

The downward pressure on our stock price caused by the sale of a significant number of shares of our common stock or the 
perception that such sales could occur by any of our significant stockholders could cause our stock price to decline, thus allowing 
short sellers of our stock an opportunity to take advantage of any decrease in the value of our stock. The presence of short sellers in 
our common stock may further depress the price of our common stock. Some of our directors and executive officers have entered into, 
or may enter into, Rule 10b5-1 trading plans pursuant to which they may sell shares of our stock from time to time in the future. 
Actual or potential sales by these insiders, including those under a pre-arranged Rule 10b5-1 trading plan, could be interpreted by the 
market as an indication that the insider has lost confidence in our stock and adversely impact the market price of our stock. 

We may be obligated to issue additional shares of our common stock to the former stockholders of SentreHEART as a result 
of our satisfaction of certain milestones set forth in the merger agreement, resulting in dilution of our current stock ownership. 

Under the terms the SentreHEART merger agreement, we could issue additional shares of our common stock, or make payments 

in cash, to the former stockholders of SentreHEART as contingent consideration upon our satisfaction of milestones described in the 
30 

  
 
merger agreements. The SentreHEART merger agreement limits the total number of shares of AtriCure common stock issued in 
connection with the acquisition to 7,021, of which 699 shares were issued at the closing of the SentreHEART acquisition on 
August 13, 2019. Issuing additional shares of our common stock in satisfaction of contingent consideration dilutes the ownership 
interests of holders of our common stock on the dates of such issuances. If we are unable to realize the strategic, operational and 
financial benefits anticipated from our acquisition of SentreHEART, our stockholders may experience dilution of their ownership 
interests in our company upon any such future issuances of shares of our common stock without receiving any commensurate benefit.  

Sales of common stock by us in a capital raising transaction or our issuances of shares in an acquisition may dilute stockholder 
ownership of common stock and cause a decline in the market price of our common stock.  

We may need to raise capital in the future to fund our operations or new initiatives or reduce or pay in full our indebtedness. If 

we raise funds by issuing equity securities, our stock price may decline and our existing stockholders may experience significant 
dilution. Furthermore, we may enter into capital raising transactions or issue shares in acquisitions at prices that represent a substantial 
discount to market price. A negative reaction by investors and securities analysts to any sale of our equity securities could result in a 
decline in the trading price of our common stock.  

Anti-takeover provisions in our amended and restated certificate of incorporation and amended and restated bylaws and 
under Delaware law could inhibit a change in control or a change in management that stockholders consider favorable.  

Provisions in our certificate of incorporation and bylaws could delay or prevent a change of control or change in management 

that would provide a premium to the market price of common stock. These provisions include those:  
• 

authorizing the issuance without further approval of “blank check” preferred stock that could be issued by our board of directors 
to increase the number of outstanding shares and thwart a takeover attempt;  

• 

• 
• 

• 

prohibiting cumulative voting in the election of directors, which would otherwise allow less than a majority of stockholders to 
elect director candidates;  

limiting the ability of stockholders to call special meetings of stockholders; 

prohibiting stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of 
stockholders; and  

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

In addition, Section 203 of the Delaware General Corporation Law limits business combination transactions with 15% 
stockholders that have not been approved by our board of directors. These provisions and others could make it difficult for a third 
party to acquire us, or for members of our board of directors to be replaced, even if doing so would be beneficial to our stockholders. 
Because our board of directors is responsible for appointing the members of our management team, these provisions could, in turn, 
affect any attempt to replace the current management team. If a change of control or change in management is delayed or prevented, 
stockholders may lose an opportunity to realize a premium on shares of common stock or the market price of our common stock could 
decline.  

We do not expect to pay dividends in the foreseeable future. As a result, stockholders must rely on stock appreciation for any 
return on investment.  

We do not anticipate paying cash dividends on our common stock in the foreseeable future. Any payment of cash dividends will 
also depend on our financial condition, results of operations, capital requirements and other factors and will be at the discretion of our 
board of directors. Accordingly, stockholders will have to rely on capital appreciation, if any, to earn a return on investment in our 
common stock. Furthermore, pursuant to our credit facility, we are currently subject to restrictions on our ability to pay dividends and 
we may in the future become subject to other contractual restrictions on, or prohibitions against, the payment of dividends.

(1)  The challenging environment resulting from the COVID-19 pandemic adversely impacted our 2020 results of operations and 
financial condition. In May 2020, we strengthened our liquidity position through a public offering of 4,574 shares of common 
stock and received net proceeds of $188,958.  

(2)  We acquired SentreHEART on August 13, 2019. Total consideration paid at the acquisition date was $18,008 in cash and 699 
shares of AtriCure common stock valued at approximately $20,307. The purchase price also included $171,300 of contingent 
consideration liabilities. 

We adopted FASB ASC 842, “Leases” using the transition method provided by Accounting Standard Update (ASU) 2018-11, 
“Leases (Topic 842): Targeted Improvements” on January 1, 2019. Under this method, we applied the new requirements to 
leases that existed as of January 1, 2019. As a result of the adoption, the Company recorded operating right-of-use assets and 
operating lease liabilities of approximately $1,884 and $2,189 as of January 1, 2019. 

(3) 

In October 2018, we raised $82,870 in net proceeds in a public offering of 2,875 shares of common stock. 

We adopted FASB ASC 606, “Revenue from Contracts with Customers” using the modified retrospective method effective 
January 1, 2018.  The adoption of ASC 606 did not have a material impact on the amount and timing of revenue recognized in 
the Consolidated Financial Statements.

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

(Dollar and share amounts referenced in this Item 7 are in thousands, except per share amounts.) 

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the 

accompanying consolidated financial statements and notes thereto contained in Item 8, “Financial Statements and Supplementary 
Data,” to provide an understanding of our results of operations, financial condition and cash flows. This section of this Form 10-K 
generally discusses 2020 and 2019 items and year-to-year comparisons between 2020 and 2019. This discussion and analysis contains 
forward-looking statements that involve risks, uncertainties and assumptions. The actual results may differ from those anticipated in 
these forward-looking statements as a result of many factors, including but not limited to those set forth under Item 1A “Risk Factors,” 
the cautionary statement regarding forward-looking statements at the beginning of Part I and elsewhere in this Form 10-K.  

Year Ended December 31, 2019 compared to December 31, 2018  

For a comparison of our results of operations for the fiscal years ended December 31, 2019 and December 31, 2018, see “Part II, 
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our annual report on Form 10-K 
for the fiscal year ended December 31, 2019, filed with the SEC on February 24, 2020. 

Overview 

We are a leading innovator in treatments for atrial fibrillation (Afib) and left atrial appendage (LAA) management. We believe 

that we are currently the market leader in the surgical treatment of Afib. Our Isolator Synergy System is approved by FDA for the 
treatment of persistent and long-standing persistent Afib concomitant to other open-heart surgical procedures. All of our other ablation 
devices are cleared for sale in the United States under FDA 510(k) clearances, including our other radio frequency (RF) and 
cryoablation products, which are indicated for the ablation of cardiac tissue and/or the treatment of cardiac arrhythmias. In addition, 
certain of our cryoablation probes are cleared for managing pain by temporarily ablating peripheral nerves. Our AtriClip products are 
510(k)-cleared with an indication for the exclusion of the LAA, performed under direct visualization and in conjunction with other 
cardiac surgical procedures. The LARIAT® system is cleared for soft tissue ligation. Several of our products are currently being 
studied to expand labeling claims or to support indications specifically for the treatment of Afib. Many of our products bear the CE 
mark and may be commercially distributed throughout the member states of the European Union and other countries that comply with 
or mirror the Medical Device Directive.  Certain products are also available in select Asia-Pacific countries. We anticipate that 
substantially all of our revenue for the foreseeable future will relate to products we currently sell, or are in the process of developing. 

We sell our products to medical centers through our direct sales force in the United States and in certain international markets, 
such as Germany, France, the United Kingdom and the Benelux region. We also sell our products to distributors who in turn sell our 
products to medical centers in other international markets. Our business is primarily transacted in U.S. Dollars with the exception of 
transactions with our European customers, which are transacted primarily in the Euro or the British Pound. 

The challenging environment resulting from the COVID-19 pandemic adversely impacted our 2020 results of operations and 

financial condition. We experienced a significant decrease in demand for our products as non-emergent procedures are being 
indeterminately deferred in order to preserve resources for COVID-19 patients and caregivers and to protect patients from potential 
exposure to COVID-19. In the second half of 2020, we began to see some hospitals resuming elective procedures although do not 
believe that most hospitals were operating at the same levels as they had historically. We continue to be impacted by the COVID-19 
pandemic and believe the effect on the Company’s business differs by geography and procedure type.  

We adjusted our operating plan and expect to continuously evaluate and as may be necessary, amend our operating plan as a 
result of the COVID-19 pandemic. We have elected to delay certain capital investments, and implemented other expense-reduction 
measures, including ceasing non-essential travel and conference activity, and suspending work on certain research and development 
projects. Adjustments to the operating plan did not include temporary or permanent reductions in headcount or to non-executive 
employee compensation. However, we are unable to ensure the operating plan adjustments we have made will be sufficient or 
sustained due to the inherent uncertainty of the unprecedented and rapidly evolving situation. We strengthened our liquidity position 
through a public offering and sale of our common stock. In May 2020, we completed an underwritten public offering of 4,574 shares 
of common stock and received net proceeds of $188,958.  

Despite the challenging environment of the COVID-19 pandemic, we continued to build on our strategic initiatives of product 
innovation, investing in clinical science and providing training and education. Throughout 2020, we conducted several meetings with 
FDA as they review our PMA submission for the EPi-Sense system, and we continue to actively work with FDA to complete the 
regulatory process. In November 2020, we submitted our responses to FDA, seeking PMA approval of the EPi-Sense system for an 
indication for treatment of symptomatic, drug-refractory, long-standing persistent atrial fibrillation, when augmented with an 
endocardial ablation catheter. AtriCure is currently waiting for feedback from FDA. We also made meaningful progress on the 
aMAZE IDE trial, continuing twelve-month post treatment follow-up with patients. We have not yet experienced a significant delay in 
patient follow-up. In addition to the progress in clinical science initiatives, we are also progressing towards 510(k) clearance of the 

35 

  
 
new ENCOMPASS® clamp and preparing for subsequent market launch. Our professional education and marketing teams have 
adapted to the pandemic by offering online and mobile trainings for physicians.  

For the year ended December 31, 2020 we reported annual revenues of $206,531, a decrease of 10.5% when compared to our 

prior year. Our net loss for fiscal year 2020 was $48,155 as compared to $35,194 for fiscal year 2019, primarily as a result of our 
decrease in revenues as a result of the COVID-19 pandemic. See the “Results of Operations” section below for additional analysis of 
our 2020 results.

Revenue. Total revenue decreased 10.5% (10.7% on a constant currency basis) due to the deferral of non-emergent procedures 
as a result of the COVID-19 pandemic. Revenue from customers in the United States decreased $16,585, or 8.9%, and revenue from 
international customers decreased $7,691, or 17.1% (18.3% on a constant currency basis). Sales in the United States declined across 
all product categories. Open ablation sales decreased $4,806, or 6.0% minimally invasive (MIS) ablation sales decreased $9,195, or 
26.4% and appendage management sales decreased $1,185, or 1.7%. The more severe decline in MIS ablation sales reflects the 
typically non-emergent nature of these procedures. However, both the AtriClip Flex·V® LAA Exclusion System (included in 
appendage management sales) and cryoSPHERE probe (included in open ablation sales) continued to grow in volume in 2020 despite 
the continued pressure of the COVID-19 pandemic. International revenue declined in both open ablation and MIS ablation products 
throughout our major European and Asia markets as a result of the global pandemic, offset by increases in the appendage management 
product line driven from increased volume of the AtriClip line. 

Revenue reported on a constant currency basis is a non-GAAP measure and is calculated by applying previous period foreign 
currency (Euro) exchange rates, which are determined by the average daily Euro to Dollar exchange rate, to each of the comparable 
periods. Revenue is analyzed on a constant currency basis to better measure the comparability of results between periods. Because 
changes in foreign currency exchange rates have a non-operating impact on revenue, we believe that evaluating growth in revenue on 
a constant currency basis provides an additional and meaningful assessment of revenue to both management and investors. 

Cost of revenue and gross margin. Cost of revenue decreased $3,250 driven primarily by reductions in sales. Partially 
offsetting the decline in cost of revenue from reduced sales are charges during the second quarter as a result of production volumes 
below normal operating levels and continued absorption of SentreHEART operations acquired in August 2019. 

Research and development expenses. Research and development expenses increased $1,840, or 4.5%. The increase in research 

and development expenses is a result of $1,156 increase in share-based compensation and $777 increase in clinical activity primarily 
driven by the aMAZE IDE clinical trial. Increases in product development project costs offset declines in regulatory submissions and 
filing fees. 

Selling, general and administrative expenses. Selling, general and administrative expenses decreased $11,755, or 7.2%. 
Personnel costs decreased $14,726 due to a decline in variable compensation and travel as a result of decreased sales and travel 
restrictions. Trade show, marketing and meeting costs decreased $4,384 as activities moved to remote platforms. Other decreases in 
expenses included $3,840 of acquisition-related expenses, $1,179 of professional services fees, $533 in bad debt expense and $322 of

recruiting fees. These decreases were offset by $6,000 expense recorded for the accrual of the value of the legal settlement with the 
former nContact stockholders, increase of $3,001 in share-based compensation and $4,559 fluctuation in the contingent consideration 
liability adjustment. See Note 12 – Commitments and Contingencies in the Consolidated Financial Statements for further discussion of 
the nContact legal settlement. See Note 3 – Fair Value in the Consolidated Financial Statements for further discussion of contingent 
consideration liabilities.  

Other income and expense. Other income and expense consists primarily of net interest expense and foreign currency 
transaction gains and losses. Net interest expense was $3,784 for 2020 and $1,713 for 2019. Interest expense relates to our term loan 
and finance lease obligations, as well as the amortization of financing costs. Interest income reflects returns on our investments, 
including gains and losses on investments sold during the period. The increase in net interest expense was driven by $1,297 lower 
interest income from lower investment yields and $774 increase in interest expense reflecting higher borrowings on the term loan due 
to the August 2019 amendment for the SentreHEART acquisition. 

Liquidity and Capital Resources  

As of December 31, 2020, we had cash, cash equivalents and investments of $258,396. All cash equivalents and investments 

and most of our operating cash are held in United States financial institutions. A minor portion of our cash is held in foreign banks for 
the operation of our international subsidiaries. Our outstanding debt was $60,000 and we had unused borrowing capacity of $8,750 
under our revolving credit facility. We had net working capital of $257,600 and an accumulated deficit of $330,352 as of 
December 31, 2020. 

Cash flows used in operating activities. We used $19,869 of net cash in operating activities during 2020, reflecting our net 

loss of $48,155 offset by $34,925 of non-cash expenses and a net decrease in cash used related to changes in operating assets and 
liabilities of $6,639. Non-cash expenses primarily included $22,642 in share-based compensation and $9,548 of depreciation and 
amortization. The net decrease in cash used related to changes in operating assets and liabilities was driven by the impact of COVID-
19, including lower customer receivables from reduced sales volumes; increased investment in inventories to protect against potential 
future production disruptions; and lower payables and accrued liabilities from lower variable compensation and reduced operating 
activities.  

Cash flows used in investing activities. We used $156,198 of net cash in investing activities during 2020, reflecting $151,739 

investment activity in available-for-sale securities largely stemming from the proceeds of our May 2020 equity offering and 
investment of $5,259 in property and equipment to support our new product introductions and maintenance and expansion of our 
existing manufacturing and distribution facilities.  

Cash flows provided by financing activities. We generated $189,392 of net cash from financing activities during 2020. This 

was primarily a result of the $188,958 net proceeds from the May 2020 public stock offering. Equity compensation plan activity 
included $10,835 proceeds from stock option exercises and $3,330 proceeds for the issuance of common stock under our employee 
stock purchase plan, offset by $13,029 shares repurchased for payment of taxes on stock awards. 

Credit facility. Our Loan and Security Agreement with Silicon Valley Bank (SVB), as amended, (Loan Agreement), provides 

for a $60,000 term loan and a $20,000 revolving line of credit. The term loan and revolving credit facility both mature or expire, as 
applicable, on August 1, 2024. Principal payments on the term loan are to be made ratably commencing March 1, 2021 through the 
loan’s maturity date. If the Company meets certain conditions, as specified in the Loan Agreement, the commencement of the term 
loan principal payments may be deferred by an additional six months. Our term loan accrues interest at the greater of the Prime Rate 
or 5.00%, plus 0.75% and is subject to an additional 3.00% fee on the $60,000 term loan principal amount, payable at maturity or 
upon acceleration or prepayment of the term loan. Our borrowing availability under the revolving credit facility is based on the lesser 
of $20,000 or a borrowing base calculation as defined by the Loan Agreement. Borrowing availability under the revolving credit 
facility is further limited by a cap on total debt outstanding under the Loan Agreement, including outstanding letters of credit, of 
$70,000. As of December 31, 2020, we had no borrowings under the revolving credit facility, and we had borrowing availability of 
$8,750. The Loan Agreement also provides for certain prepayment and early termination fees only if the term loan is repaid before 
August 2024 and establishes a minimum liquidity ratio and dividend restrictions, along with other customary terms and conditions. 
Specified assets have been pledged as collateral. We are in compliance with the covenants of the Loan Agreement as of December 31, 
2020. 

On February 8, 2021, the Company and SVB entered into an amendment to the Loan Agreement which modified conditions 

which allow the Company to request to defer the term loan principal payments an additional six months, commencing in September 
2021, if such conditions are so satisfied. Subsequent to the amendment, the conditions were satisfied by the Company and the 
Company requested such deferral. As a result, borrowings outstanding under the existing term loan agreement have been classified to 
reflect the deferral of principal payments in the Consolidated Balance Sheet as of December 31, 2020. 

Our corporate headquarters lease agreement requires a $1,250 letter of credit which renews annually and remains outstanding as 

of December 31, 2020. 

37 

  
 
Uses of liquidity and capital resources. Our future capital requirements depend on a number of factors, including market 
acceptance of our current and future products; the resources we devote to developing and supporting our products; future expenses to 
expand and support our sales and marketing efforts; costs relating to changes in regulatory policies or laws that affect our operations 
and cost of filings; costs associated with clinical trials and securing regulatory approval for new products; costs associated with 
acquiring and integrating businesses; costs associated with prosecuting, defending and enforcing our intellectual property rights; and 
possible acquisitions and joint ventures. Global economic turmoil, including the impact of the COVID-19 pandemic, has evolved 
rapidly over the past year and may continue to adversely impact our revenue, thus having an adverse impact on our operating results 
and financial condition. We continue to evaluate additional measures to maintain financial flexibility, and we will continue to closely 
monitor our liquidity and capital resources through the disruption caused by COVID-19. 

We have on file with the SEC a shelf registration statement which allows us to sell any combination of senior or subordinated 

debt securities, common stock, preferred stock, warrants, depository shares and units in one or more offerings should we choose to do 
so in the future. We expect to maintain the effectiveness of this shelf registration statement for the foreseeable future. In May 2020, 
we completed a public offering of 4,574 shares of our common stock, and received net proceeds of $188,958 after underwriting 
discounts and commissions and offering costs. 

We believe that our current cash, cash equivalents and investments, along with the cash we expect to generate or use for 
operations or access via our term loan and revolving line of credit, will be sufficient to meet our anticipated cash needs for working 
capital and capital expenditures for at least the next twelve months. The SentreHEART acquisition provides for contingent 
consideration to be paid upon PMA approval before December 2023 and CPT reimbursement before December 2026. Subject to the 
terms and conditions of the SentreHEART merger agreement, such contingent consideration will be paid in AtriCure common stock 
and cash, up to a specified maximum number of shares. Over the next twelve months, we do not expect our cash requirements to 
include significant payments of contingent consideration based on terms of the acquisition agreement and progress towards 
achievement of the related milestones.  

If our sources of cash are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or debt 
securities or obtain a revised or additional credit facility. The sale of additional equity or convertible debt securities could result in 
dilution to our stockholders. If additional funds are raised through the issuance of debt securities, these securities could have rights 
senior to those associated with our common stock and could contain covenants that would restrict our operations. Finally, our term 
loan agreement and revolving line of credit require compliance with certain financial and other covenants. If we are unable to maintain 
these financing arrangements, we may be required to reduce the scope of our planned research and development, clinical activities and 
selling, training, education and marketing efforts.

Long-term debt represents principal repayments related to our term loan. See Note 10 – Indebtedness regarding applicable 
interest and fee payments.  

Finance leases consist of principal and interest payments related to our Mason, Ohio headquarters and computer equipment. See 
Note 11 – Leases.  

(3)  Represents lease commitments under various operating leases, primarily for office and warehouse space. See Note 11 – Leases. 

(4)  Represents obligations for royalty agreements ranging from 3% to 5% of specified product sales estimated using 2020 sales. 

Royalty obligations beyond one year have not been included as payments are based on specified product sales and not estimable 
at this time. See Note 12 – Commitments and Contingencies to our Consolidated Financial Statements.  

We have contractual obligations for contingent consideration payments related to the SentreHEART acquisition. Subject to the 
terms and conditions of the SentreHEART merger agreement, such contingent consideration will be paid in AtriCure common stock 
and cash, up to a specified maximum number of shares. The SentreHEART milestones expire on December 31, 2023 and 
December 31, 2026. See Note 3 – Fair Value. 

Off-Balance-Sheet Arrangements  

We are not a party to any off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material 
effect on our financial condition, changes in financial condition, sales or expenses, results of operations, liquidity, capital expenditures 
or capital resources.  

Inflation  

Inflation has not had a significant impact on our historical operations, and we do not expect it to have a significant impact on our 

results of operations or financial condition in the foreseeable future.  

Critical Accounting Policies and Estimates 

Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial 

statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The 
preparation of consolidated financial statements requires management to make estimates and judgments that affect the reported 
amounts of assets and liabilities, revenue and expenses, and disclosures of contingent assets and liabilities at the date of the financial 
statements. On a periodic basis, we evaluate our estimates, using authoritative pronouncements, historical experience and other 
assumptions as the basis for making estimates. Actual results could differ from those estimates under different assumptions or 
conditions. We have described our significant accounting policies in Note 1 – Description of Business and Summary of Significant 
Accounting Policies to our consolidated financial statements included in this Form 10-K. 

We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation 

of our consolidated financial statements.  

Revenue Recognition— Revenue is generated primarily from the sale of medical devices. We recognize revenue in an amount 

that reflects the consideration we expect to be entitled to in exchange for those devices when control of promised devices is transferred 
to customers. At contract inception, we assess the products promised in contracts with customers and identify a performance 
obligation for each promise to transfer to the customer a product that is distinct. Our devices are distinct and represent performance 
obligations. These performance obligations are satisfied and revenue is recognized at a point in time upon shipment or delivery of 
products. Sales of devices are categorized as follows: open ablation, minimally invasive ablation, appendage management and valve 
tools. Shipping and handling activities performed after control over products transfers to customers are considered activities to fulfill 
the promise to transfer the products rather than as separate promises to customers. Products are sold primarily through our direct sales

force and through distributors in certain international markets. Terms of sale are generally consistent for both end-users and 
distributors, except that payment terms are generally net 30 days for end-users and net 60 days for distributors, with limited 
exceptions. We do not maintain any post-shipping obligations to customers. No installation, calibration or testing of products is 
performed by the Company subsequent to shipment in order to render products operational.  

We account for revenue in accordance with FASB ASC 606, “Revenue from Contracts with Customers”. Significant judgments 

and estimates involved in the Company’s recognition of revenue include the estimation of a provision for returns. We estimate the 
provision for sales returns and allowances using the expected value method based on historical experience and other factors that we 
believe could impact our expected returns, including defective or damaged products and invoice adjustments. In the normal course of 
business, we generally do not accept product returns unless a product is defective as manufactured, and we do not provide customers 
with the right to a refund. 

Allowance for Credit Losses on Accounts Receivable—We evaluate the expected credit losses of accounts receivable, 

considering historical credit losses, current customer-specific information and other relevant factors when determining the allowance. 
An increase to the allowance for credit losses results in a corresponding increase in selling, general and administrative expenses. We 
charge off uncollectible receivables against the allowance when all attempts to collect the receivable have failed. Our history of write-
offs has not been significant. 

Inventories—Our inventories are stated at the lower of cost or net realizable value based on the first-in, first-out cost method 

(FIFO) and consist of raw materials, work in process and finished goods. Our industry is characterized by rapid product development 
and frequent new product introductions. Uncertain timing of product approvals, variability in product launch strategies and variation 
in product use all impact inventory reserves for excess, obsolete and expired products. An increase to inventory reserves results in a 
corresponding increase in cost of revenue. Inventories are written off against the reserve when they are physically disposed. 

Property and Equipment—We state property and equipment at cost less accumulated depreciation. Depreciation is computed 

using the straight-line method and applied over the estimated useful lives of the assets. Included in property and equipment are 
generators and other capital equipment (such as our RF and cryo generators) that are placed with direct customers that use our 
disposable products. These generators and other capital equipment are depreciated over a period of one to three years, which 
approximates their useful lives, and such depreciation is included in cost of revenue. We estimate the useful lives of this equipment 
based on anticipated usage by our customers and the timing and impact of our expected new technology rollouts. To the extent we 
experience changes in the usage of this equipment or the introductions of new technologies, the estimated useful lives of this 
equipment may change in a future period.  

IPR&D Intangible Asset—In Process Research and Development (IPR&D) represents the value of acquired technology which 

has not yet reached technological feasibility. The primary basis for determining the technological feasibility is obtaining specific 
regulatory approvals. IPR&D is accounted for as an indefinite-lived intangible asset until completion or abandonment of the IPR&D 
project. Upon completion of the development project, the IPR&D will be amortized over its estimated useful life. The IPR&D asset 
represents an estimate of the fair value of the PMA that may result from the CONVERGE IDE and aMAZE IDE clinical trials. We 
review intangible assets for impairment annually on October 1, or more often if impairment indicators are present, using our best 
estimates based on reasonable and supportable assumptions and projections of expected future cash flows. If the IPR&D project is 
abandoned or regulatory approvals are not obtained, we may have a full or partial impairment charge related to the IPR&D, calculated 
as the excess carrying value of the IPR&D assets over the estimated fair value. 

Goodwill— Goodwill represents the excess of purchase price over the fair value of the net assets acquired in business 
combinations. Our goodwill is accounted for in a single reporting unit representing the Company as a whole. We test goodwill for 
impairment annually on October 1 or more often if impairment indicators are present. The impairment test requires a comparison of 
the estimated fair value of the reporting unit to the carrying value of the assets and liabilities of that reporting unit. If the carrying 
value of the reporting unit exceeds the fair value of the reporting unit, the carrying value of the reporting unit’s goodwill is reduced to 
its fair value through an impairment charge to adjust the goodwill balance. The estimates of fair value and the determination of 
reporting units requires management judgment.   

Share-Based Employee Compensation—We account for share-based compensation for all share-based payment awards, 
including stock options, restricted stock awards, restricted stock units, performance share awards, and stock purchases related to an 
employee stock purchase plan, based on their estimated fair values. We estimate the fair value of time-based options on the date of 
grant using the Black-Scholes option pricing model (Black-Scholes model). Our determination of fair value of share-based payment 
awards is affected by our stock price, as well as assumptions regarding a number of subjective variables. These variables include but 
are not limited to our expected stock price volatility over the term of the awards and actual and projected employee stock option 
exercise behaviors. The value of the portion of the awards that is ultimately expected to vest is recognized as expense over the 
requisite service periods in our Consolidated Statements of Operations and Comprehensive Loss.  

40 

  
 
We estimate the fair value of restricted stock awards, restricted stock units and performance share awards based upon the grant 

date closing market price of our common stock. The estimated fair value of the performance share awards may be adjusted over the 
performance period based on estimates of performance target achievement.  

We also have an employee stock purchase plan (ESPP) which is available to all eligible employees as defined by the plan 

document. Under the ESPP, shares of our common stock may be purchased at a discount. We estimate the number of shares to be 
purchased under the ESPP at the beginning of the purchase period and calculate estimated compensation expense using the Black-
Scholes model based upon the fair value of the stock at the beginning of the purchase period. Compensation expense is recognized 
over each purchase period, and expense is adjusted at the time of stock purchase.  

Contingent Consideration—Contingent consideration arrangements obligate the Company to pay former shareholders of 

acquired companies certain amounts if specified future events occur or conditions are met, such as the achievement of certain 
regulatory milestones or reimbursement milestones. We measure such liabilities using unobservable inputs by applying the 
probability-weighted scenario method. Various key assumptions, such as the probability and timing of achievement of the agreed 
milestones, are used in the determination of fair value of contingent consideration arrangements and are not observable in the market. 
Subsequent revisions to key assumptions, which impact the estimated fair value of contingent consideration liabilities, are reflected in 
selling, general and administrative expenses.  

Income Taxes—Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to 

differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and 
operating loss and tax credit carryforwards. We measure deferred income tax assets and liabilities using enacted tax rates expected to 
apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on 
deferred income tax assets and liabilities from changes in tax rates is recognized in the period that includes the enactment date. 

Our estimate of the valuation allowance for deferred tax assets requires us to make significant estimates and judgments about 

our future operating results. Deferred income tax assets are reduced by valuation allowances if, based on the consideration of all 
available evidence, it is more-likely-than-not that some portion of the deferred tax asset will not be realized. Significant weight is 
given to evidence that can be objectively verified. We evaluate deferred income tax assets on an annual basis to determine if valuation 
allowances are required by considering all available evidence. Deferred income tax assets are realized by having sufficient future 
taxable income to allow the related tax benefits to reduce taxes otherwise payable. The sources of taxable income that may be 
available to realize the benefit of deferred tax assets are future reversals of existing taxable temporary differences, future taxable 
income, exclusive of reversing temporary differences and carryforwards and tax planning strategies that are both prudent and feasible. 
In evaluating whether to record a valuation allowance, the applicable accounting standards deem that the existence of cumulative 
losses in recent years is a significant piece of objectively verifiable negative evidence that must be overcome by objectively verifiable 
positive evidence to avoid the need to record a valuation allowance. We have recorded a valuation allowance against substantially all 
net deferred income tax assets as it is more-likely-than-not that the benefit of such deferred income tax assets will not be recognized in 
future periods.  

We believe our critical accounting policies regarding revenue recognition, allowance for credit losses on accounts receivable, 

inventories, property and equipment, IPR&D intangible asset, goodwill, share-based employee compensation, contingent 
consideration and income taxes affect our more significant judgments and estimates used in the preparation of our consolidated 
financial statements. We base our judgments and estimates on historical experience, current conditions and other reasonable factors.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

(Amounts referenced in this Item 7A are in thousands, except per share amounts.) 

The Company is exposed to various market risks, which include potential losses arising from adverse changes in market rates 
and prices, such as foreign exchange fluctuations and changes in interest rates. Interest on the term loan and revolving credit facility 
accrue at a variable rate based on the Prime Rate. 

Products sold by AtriCure Europe, B.V. accounted for 10.9% and 11.7% of the Company’s total revenue for the years ended 

December 31, 2020 and 2019. Since such revenue was primarily denominated in Euros or British Pounds, the Company is exposed to 
exchange rate fluctuations between the Euro and the U.S. Dollar and between the British Pound and the Euro. For the years ended 
December 31, 2020 and 2019, foreign currency transaction gains of $44 and $180 were recorded primarily in connection with 
settlements of the intercompany balances and invoices transacted in British Pounds. For revenue denominated in Euros, if there is an 
increase in the rate at which Euros are exchanged for U.S. Dollars, it will require more Euros to equal a specified amount of U.S. 
Dollars than before the rate increase. In such cases, and if products are priced in Euros, the Company will receive less in U.S. Dollars 
than was received before the rate increase went into effect. The Euro to U.S. Dollar conversion rate fluctuations may impact our 
reported revenue and expenses. In other international markets, the Company denominates sales in U.S. Dollars. If products are priced 
in U.S. Dollars and competitors price their products in the local currency, an increase in the relative strength of the U.S. Dollar could 
result in the Company’s price not being competitive in a market where business is not transacted in U.S. Dollars. 

The Company invests its cash primarily in money market accounts, repurchase agreements, U.S. government and agency 
obligations, corporate bonds, asset-backed securities and commercial paper. Although the Company believes its cash to be invested in 
a conservative manner, with cash preservation being the primary investment objective, the value of the securities held will fluctuate 
with changes in the financial markets including, among other things, changes in interest rates, credit quality and general volatility. 
This risk is managed by investing in high quality investment grade securities. 

Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents balances and 
investments in corporate bonds. Certain of AtriCure’s cash and cash equivalents balances exceed FDIC insured limits or are invested 
in money market accounts with investment banks that are not FDIC-insured. The Company places its cash and cash equivalents in 
what it believes to be credit-worthy financial institutions. As of December 31, 2020, $41,694 of the cash and cash equivalents balance 
was in excess of FDIC limits.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  

To the stockholders and the Board of Directors of  
AtriCure, Inc. 
Mason, Ohio  

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of AtriCure, Inc. and subsidiaries (the "Company") as of 
December 31, 2020 and 2019, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and 
cash flows, for each of the three years in the period ended December 31, 2020, and the related notes and the schedule listed in the 
Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all 
material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its 
cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally 
accepted in the United States of America. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal 
Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our 
report dated February 26, 2021, expressed an unqualified opinion on the Company's internal control over financial reporting. 

Basis for Opinion 

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

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

Critical Audit Matters 

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were 
communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to 
the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical 
audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating 
the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which 
they relate. 

Valuation of Contingent Consideration Pursuant to the SentreHEART Merger Agreement - Refer to Note 3 to the financial 
statements  

Critical Audit Matter Description 

The Company has a contingent consideration arrangement of $184.8 million as of December 31, 2020 arising from the 2019 
SentreHEART acquisition which obligates the Company to pay former shareholders of the acquired company certain amounts if 
specified future events occur or conditions are met, such as the achievement of certain regulatory or reimbursement milestones 
(“milestones”). The Company measured the liability associated with the contingent consideration arrangement at fair value, using 
unobservable inputs by applying the probability-weighted scenario method. Various key assumptions, including the probability and 
timing of achievement of regulatory or reimbursement milestones (“key assumptions”), are used in the determination of fair value of 
the contingent consideration arrangement and are not observable in the market, thus representing a Level 3 measurement within the 
fair value hierarchy. Given that the valuation of the contingent consideration arrangement is based on unobservable inputs and is 
sensitive to changes in the probability and timing of achievement of the milestones, auditing these key assumptions required a high 
degree of auditor judgment and an increased extent of effort.  

44 

  
 
 
 
 
How the Critical Audit Matter Was Addressed in the Audit 

Our audit procedures related to the Company’s key assumptions used in the determination of the fair value of the contingent 
consideration arrangement included the following, among others:  
•  We inquired of management and the Company’s clinical research personnel to understand each milestone and key assumptions, 

including current progress and any clinical results received to date.    

•  We tested the design and operating effectiveness of the Company’s internal controls over management’s estimates of key 
assumptions used in the valuation of the contingent consideration arrangement, including consideration of the impact on 
assumptions from the COVID-19 pandemic. 

•  We evaluated management’s ability to accurately project the key assumptions by comparing actual progress to management’s 

historical projections. 

•  We evaluated the reasonableness of the key assumptions by comparing them to (1) internal communications to management and 

the Board of Directors and (2) information included in the Company’s external communications. 

•  We examined regulatory trends to consider the impact of changes in the regulatory environment on the key assumptions. 
•  We independently corroborated the reasonableness of the key assumptions by verifying the process and timing necessary to 

achieve each milestone. 

Valuation of the In Process Research and Development Intangible Asset Pursuant to the nContact Merger Agreement — Refer to 
Note 6 to the financial statements 

Critical Audit Matter Description 

The Company has an in process research and development (IPR&D) intangible asset arising from the 2015 nContact acquisition in the 
amount of $44.0 million. On at least an annual basis, the Company performs impairment testing on the IPR&D intangible asset, by 
comparing the carrying value to the estimated fair value. An impairment charge is required if the carrying value of the IPR&D 
intangible asset is in excess of the estimated fair value. Estimated fair value is measured using the excess earnings method and key 
cash flow assumptions, such as revenue growth rates, related profit margins, and obsolescence rates (“key cash flow assumptions”). 
Given that the determination of the estimated fair value of the IPR&D intangible asset required management to make significant 
estimates related to key cash flows assumptions, auditing these key cash flow assumptions required a high degree of auditor judgment 
and an increased extent of effort, including the need to involve our fair value specialists. 

How the Critical Audit Matter Was Addressed in the Audit 

Our audit procedures related to the Company’s key assumptions used in the determination of the fair value of the IPR&D intangible 
asset arising from the 2015 nContact acquisition included the following, among others:  
•  We inquired of management and the Company’s commercial personnel to understand the key cash flow assumptions. 
•  We tested the design and operating effectiveness of the Company’s internal controls over management’s estimates of key cash 

flow assumptions used in the valuation of the IPR&D intangible asset. 

•  We evaluated whether the key cash flow assumptions used were reasonable by considering industry data and current market 

forecasts, including consideration of the effects of the COVID-19 pandemic, and whether such assumptions were consistent with 
evidence obtained in other areas of the audit. 

•  We evaluated management’s ability to accurately project the key cash flow assumptions by comparing actual progress to 

management’s historical projections. 

•  With the assistance of our fair value specialists, we evaluated the reasonableness of the significant valuation assumptions and 

calculations by: 

  Evaluating the excess earnings method, 
  Testing the reasonableness of the valuation assumptions utilized, including the discount rate, and 
  Testing the mathematical accuracy of the discounted cash flows used to determine the estimated fair value of the 

IPR&D intangible asset.

ATRICURE, INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 
(In Thousands, Except Per Share Amounts) 

1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Nature of the Business—The “Company” or “AtriCure” consists of AtriCure, Inc. and its wholly-owned subsidiaries. The 

Company is a leading innovator in treatments for atrial fibrillation (Afib) and left atrial appendage (LAA) management and sells its 
products to medical centers globally through its direct sales force and distributors. 

Principles of Consolidation—The Consolidated Financial Statements include the accounts of AtriCure, Inc. and our wholly-

owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.  

Cash and Cash Equivalents—The Company considers highly liquid investments with maturities of three months or less at the 
date of purchase as cash equivalents. Cash equivalents include demand deposits, money market funds and repurchase agreements on 
deposit with certain financial institutions. 

Investments—The Company makes investments primarily in U.S. government and agency obligations, corporate bonds, 
commercial paper and asset-backed securities and classifies all investments as available-for-sale. Investments with maturities of less 
than one year are classified as short-term. Investments are recorded at fair value, with unrealized gains and losses recorded as 
accumulated other comprehensive income (loss). Gains and losses are recognized using the specific identification method when 
securities are sold and are included in interest income.  

Revenue Recognition—The Company recognizes revenue when control of promised goods is transferred to customers in an 

amount that reflects the consideration the Company expects to be entitled to in exchange for those goods. This generally occurs upon 
shipment of goods to customers. See Note 13 for further discussion on revenue.  

Sales Returns and Allowances—The Company maintains a provision for potential returns of defective or damaged products, 

and invoice adjustments. The Company adjusts the provision using the expected value method based on historical experience. 
Increases to the provision result in a reduction of revenue, and the provision is included in accrued liabilities. 

Allowance for Credit Losses on Accounts Receivable—The Company evaluates the expected credit losses of accounts 

receivable, considering historical credit losses, current customer-specific information and other relevant factors when determining the 
allowance. An increase to the allowance for credit losses results in a corresponding increase in selling, general and administrative 
expenses. The Company charges off uncollectible receivables against the allowance when all attempts to collect the receivable have 
failed. The Company’s history of write-offs has not been significant. 

 Inventories—Inventories are stated at the lower of cost or net realizable value based on the first-in, first-out cost method and 

consist of raw materials, work in process and finished goods. The Company’s industry is characterized by rapid product development 
and frequent new product introductions. Uncertain timing of product approvals, variability in product launch strategies and variation 
in product use all impact inventory reserves for excess, obsolete and expired products. An increase to inventory reserves results in a 
corresponding increase in cost of revenue. Inventories are written off against the reserve when they are physically disposed.  

Property and Equipment—Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed 

using the straight-line method over the estimated useful lives of assets (see Note 8). The Company reassesses the useful lives of 
property and equipment at least annually and retires assets if they are no longer in service. Maintenance and repair costs are expensed 
as incurred.  

The Company’s RF and cryo generators are generally placed with customers served by our direct sales force. The estimated 
useful lives of this equipment are based on anticipated usage by customers and the timing and impact of expected new technology 
rollouts by the Company and may change in a future period if the Company experiences changes in the usage of the equipment or 
introduces new technologies. Depreciation related to generators and other capital equipment is recorded in cost of revenue.  

The Company reviews property and equipment for impairment at least annually using its best estimates based on reasonable and 

supportable assumptions and projections of expected future cash flows. Property and equipment impairments recorded by the 
Company have not been significant. 

Leases—The Company determines if an arrangement is a lease at inception of the contract. The Company applies the short-term 

lease recognition exemption, recognizing lease payments in profit or loss for leases that have a lease term of 12 months or less at 
commencement and do not include a purchase option whose exercise is reasonably certain. Operating leases are included in operating 
lease right-of-use (ROU) assets, other current liabilities and current maturities of debt and leases, and operating lease liabilities. 
Finance leases are included in property and equipment, other current liabilities and current maturities of debt and leases, and finance 
lease liabilities.  

50 

 
  
 
ATRICURE, INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 
(In Thousands, Except Per Share Amounts) 

ROU assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make 

lease payments arising from the lease. Operating lease ROU assets and liabilities are measured and recorded at the commencement 
date based on the present value of lease payments over the lease term. The operating lease ROU asset excludes lease incentives. The 
Company uses the implicit rate when readily determinable, however, most of the leases do not provide an implicit rate and therefore, 
the Company uses the incremental borrowing rate based on the information available at measurement. The lease terms may include 
options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. For real estate and 
equipment leases, the Company accounts for the lease and non-lease components as a single lease component. Additionally, the 
portfolio approach is applied to effectively account for the operating lease ROU assets and liabilities based on the term of the 
underlying lease. Lease expense is recognized on a straight-line basis over the lease term. See Note 11 for further discussion. 

Intangible Assets—Intangible assets with determinable useful lives are amortized on a straight-line basis over the estimated 

periods benefited. The Company reassesses the useful lives of intangible assets annually. 

Included in intangible assets is In Process Research and Development (IPR&D), representing the value of acquired technologies 

which have not yet reached technological feasibility. The primary basis for determining the technological feasibility is obtaining 
specific regulatory approvals. IPR&D is accounted for as an indefinite-lived intangible asset until completion or abandonment of the 
IPR&D project. Upon completion of the development project, the IPR&D will be amortized over its estimated useful life. The IPR&D 
assets represent estimates of the fair value of the pre-market approval (PMA) that could result from the CONVERGE IDE and 
aMAZE IDE clinical trials. If the IPR&D project is abandoned or regulatory approvals are not obtained, the Company may have a full 
or partial impairment charge related to the IPR&D, calculated as the excess carrying value of the IPR&D assets over the estimated fair 
value.  

The Company reviews intangible assets for impairment using its best estimates based on reasonable and supportable 

assumptions and projections of expected future cash flows. The Company performs impairment testing annually on October 1 or more 
often if impairment indicators are present.  

Goodwill—Goodwill represents the excess of purchase price over the fair value of the net assets acquired in business 

combinations. The Company’s goodwill is accounted for in a single reporting unit representing the Company as a whole. The 
Company tests goodwill for impairment annually on October 1, or more often if impairment indicators are present.  

Contingent Consideration and other Noncurrent Liabilities—This balance consists of the contingent consideration recorded in 

business combinations, as well as deferred payroll taxes as a result of the Coronavirus Aid, Relief, and Economic Security Act 
(CARES Act), deferred revenues, asset retirement obligations and other contractual obligations. The contingent consideration balance 
is included in noncurrent liabilities as such settlement is both required and expected to be made primarily in shares of the Company’s 
common stock pursuant to the SentreHEART merger agreement.  

Other Income (Expense)—Other income (expense) consists of foreign currency transaction gains and losses generated by 

settlements of intercompany balances denominated in Euros and invoices transacted in British Pounds. 

Income Taxes— Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to 
differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and 
operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to 
apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on 
deferred income tax assets and liabilities from a change in tax rates is recognized in the period that includes the enactment date.  

The Company’s estimate of the valuation allowance for deferred income tax assets requires significant estimates and judgments 

about future operating results. Deferred income tax assets are reduced by valuation allowances if, based on the consideration of all 
available evidence, it is more-likely-than-not that the deferred income tax asset will not be realized. Significant weight is given to 
evidence that can be objectively verified. The Company evaluates deferred income tax assets on an annual basis to determine if 
valuation allowances are required. Deferred income tax assets are realized by having sufficient future taxable income to allow the 
related tax benefits to reduce taxes otherwise payable. The sources of taxable income that may be available to realize the benefit of 
deferred income tax assets are future reversals of existing taxable temporary differences, future taxable income, exclusive of reversing 
temporary differences and carryforwards, and tax planning strategies that are both prudent and feasible. In evaluating the need for a 
valuation allowance, the existence of cumulative losses in recent years is significant objectively verifiable negative evidence that must 
be overcome by objectively verifiable positive evidence to avoid the need to record a valuation allowance. The Company has recorded 
a valuation allowance against substantially all net deferred income tax assets as it is more-likely-than-not that the benefit of the 
deferred income tax assets will not be recognized in future periods. The Tax Cut and Jobs Act (Tax Reform Act) allows companies an 
election to reclassify the income tax effects of the Tax Reform Act on items within accumulated other comprehensive income (loss) to 
retained earnings. The Company has not made this election due to its full valuation allowance.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 
(In Thousands, Except Per Share Amounts) 

Net Loss Per Share—Basic and diluted net loss per share is computed by dividing the net loss by the weighted average number 
of common shares outstanding during the period. Since the Company has experienced net losses for all periods presented, net loss per 
share excludes the effect of 2,301, 3,623 and 3,869 stock options, restricted stock awards, restricted stock units and performance share 
awards as of December 31, 2020, 2019 and 2018 because they are anti-dilutive. Therefore, the number of shares calculated for basic 
net loss per share is also used for the diluted net loss per share calculation.  

Comprehensive Income (Loss) and Accumulated Other Comprehensive Income (Loss)—In addition to net losses, the 
comprehensive income/loss includes foreign currency translation adjustments and unrealized gains and losses on investments.  

Accumulated other comprehensive (loss) income consisted of the following (net of tax):  

Total accumulated other comprehensive (loss) income at beginning of period  
Unrealized gains (losses) on investments 
Balance at beginning of period  
Other comprehensive (loss) income before reclassifications  
Amounts reclassified from accumulated other comprehensive (loss) income  
to interest income  
Balance at end of period  
Foreign currency translation adjustment 
Balance at beginning of period  
Other comprehensive income (loss) before reclassifications  
Amounts reclassified from accumulated other comprehensive (loss) income  
to other (expense) income  
Balance at end of period

Research and Development Costs—Research and development costs are expensed as incurred. These costs include 
compensation and other internal and external costs associated with the development of and research related to new and existing 
products or concepts, preclinical studies, clinical trials, scientific and regulatory affairs. 

Advertising Costs— The Company expenses advertising costs as incurred. Advertising expense was $655, $635 and $785 

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

Share-Based Compensation—The Company records share-based compensation for all share-based payment awards, including 

stock options, restricted stock, performance shares and stock purchases related to an employee stock purchase plan, based on 
estimated fair values.  

The Company estimates the fair value of share-based payment awards on the date of grant. The value of the portion of the award 

that is ultimately expected to vest is recognized as expense over the requisite service periods in the Consolidated Statements of 
Operations and Comprehensive Loss. The Company estimates forfeitures at the time of grant and revises them, if necessary, in 
subsequent periods if actual forfeitures differ from those estimates.  

The Company estimates the fair value of time-based options on the date of grant using the Black-Scholes option-pricing model 
(Black-Scholes model). The Company’s determination of fair value is affected by the Company’s stock price, as well as assumptions 
regarding several subjective variables. These variables include, but are not limited to, the Company’s expected stock price volatility 
over the term of the awards and actual and projected employee stock option exercise behaviors. The value of the portion of the awards 
that is ultimately expected to vest is recognized as expense over the requisite service periods in the Consolidated Statements of 
Operations and Comprehensive Loss. The Company estimates the fair value of restricted stock awards, restricted stock units and 
performance share awards based upon the grant date closing market price of the Company’s common stock. The estimated fair value 
of performance share awards may be adjusted over the performance period based on changes to estimates of performance target 
achievement. 

The Company also has an employee stock purchase plan (ESPP) which is available to all eligible employees as defined by the 

plan document. Under the ESPP, shares of the Company’s common stock may be purchased at a discount. The Company estimates the 
number of shares to be purchased under the ESPP at the beginning of each purchase period based upon the fair value of the stock at 
the beginning of the purchase period using the Black-Scholes model and records estimated compensation expense during the period. 
Expense is adjusted at the time of stock purchase.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 
(In Thousands, Except Per Share Amounts) 

Use of Estimates—The preparation of the financial statements in conformity with accounting principles generally accepted in 
the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of 
assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of 
revenue and expense during the reporting period. Actual results could differ from those estimates.  

Fair Value Disclosures— The Company classifies cash investments in U.S. government and agency obligations, accounts 
receivable, short-term other assets, accounts payable and accrued liabilities as Level 1. The carrying amounts of these assets and 
liabilities approximate their fair value due to their relatively short-term nature. Cash equivalents and investments in corporate bonds, 
repurchase agreements, commercial paper and asset-backed securities are classified as Level 2 within the fair value hierarchy. The fair 
value of fixed term debt is estimated by calculating the net present value of future debt payments at current market interest rates and is 
classified as Level 2. The book value of the Company’s fixed term debt approximates its fair value because the interest rate varies 
with market rates. Significant unobservable inputs with respect to the fair value measurements of the Level 3 contingent consideration 
liabilities are developed using Company data. See Note 3 – Fair Value for further information on fair value measurements.  

2. RECENT ACCOUNTING PRONOUNCEMENTS 

In June 2016, the FASB issued Accounting Standard Update (ASU) 2016-13, “Financial Instruments – Credit Losses (Topic 

326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13). This guidance requires that financial assets measured 
at amortized costs, such as trade receivables and contract assets, be presented net of expected credit losses, which may be estimated 
based on relevant information such as historical experience, current conditions and future expectations for each pool of similar 
financial assets. The Company has applied the new requirements by calculating and recording an allowance for credit losses on trade 
receivables as of January 1, 2020. As a result of the adoption, the Company adjusted its allowance for credit losses on trade 
receivables; however, the adjustment did not have a material impact on its consolidated financial statements and related disclosures. 

In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Accounting 

for Goodwill Impairment” (ASU 2017-04). The guidance removes the requirement to perform a hypothetical purchase price allocation 
to measure goodwill impairment. Under ASU 2017-04, a goodwill impairment will be the amount by which a reporting unit’s carrying 
value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance becomes effective for annual reporting 
periods beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted, and applied 
prospectively. The Company has adopted this guidance as of January 1, 2020, and the adoption of this standard did not have a material 
impact on its consolidated financial statements and related disclosures. 

3. FAIR VALUE 

FASB ASC 820, “Fair Value Measurements and Disclosures” (ASC 820), defines fair value as the exchange price that would be 
received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability 
in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must 
maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels 
of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:  
•  Level 1—Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the 

measurement date. An active market for the asset or liability is a market in which transactions for the asset or liability occur with 
sufficient frequency and volume to provide pricing information on an ongoing basis. The valuation under this approach does not 
entail a significant degree of judgment.  

•  Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or 
liabilities; 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 assets or liabilities. The valuation technique for the Company’s Level 2 assets is 
based on quoted market prices for similar assets from observable pricing sources at the reporting date.  

•  Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the 

assets or liabilities. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available, 
thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.

There were no changes in the levels or methodology of measurement of financial assets and liabilities during the years ended 

December 31, 2020 and 2019. 

Contingent Consideration. The Company has contingent consideration arrangements arising from the nContact and 

SentreHEART acquisitions.  

Contingent consideration arrangements under the nContact merger agreement obligated the Company to pay former 

shareholders of nContact up to $50,000 for the completion of enrollment of the CONVERGE IDE trial (Trial Enrollment Milestone) 
and corresponding PMA approval by December 31, 2020 (Regulatory Milestone). nContact shareholders were also entitled to 
additional sales-based contingent consideration on revenue in excess of an annual growth rate of more than 25% over a specified 
baseline through 2019 (Commercial Milestone). No payments were made under the Commercial Milestone for calendar years 2016 
through 2019 as revenues did not exceed the targets for these years. The Company completed patient enrollment on August 21, 2018, 
and cash payment of $1,221 and issuance of 232 shares of common stock was made to former nContact shareholders for the Trial 
Enrollment Milestone on September 20, 2018. No payments were made for the Regulatory Milestone as the Company did not obtain 
PMA approval from FDA for the Epi-Sense Guided Coagulation System as of December 31, 2020. Therefore, as of December 31, 
2020, the terms of the contingent consideration arrangements under the nContact merger agreement expired and the underlying fair 
value is $0.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 
(In Thousands, Except Per Share Amounts) 

Contingent consideration arrangements under the SentreHEART merger agreement obligate the Company to pay former 

shareholders of SentreHEART for the following milestones, if achieved: 
•  PMA Milestone – up to $140,000 upon receiving PMA from FDA for the LARIAT system with an approved indication allowing 
commercial distribution in the United States for the exclusion of the LAA for treatment of atrial fibrillation. The full contingent 
consideration amount is only received if PMA approval is received on or before December 31, 2022. The potential contingent 
consideration is reduced by 4.17% (or one-twenty-fourth) each month following December 2022 and is reduced to zero if the 
milestone is achieved after December 31, 2023. Payment of $25,000 of the PMA milestone may be accelerated upon achievement 
of an Interim Success Milestone as defined by the merger agreement. 

•  CPT Reimbursement Milestone – up to $120,000 upon American Medical Association approval of a Medicare Category 1 Current 
Procedural Terminology (CPT) Code. The full contingent consideration amount is only received if approval of the CPT Code is 
received on or before December 31, 2025. The potential contingent consideration is reduced by 4.17% (or one-twenty-fourth) 
each month following December 2025 and is reduced to zero if the milestone is achieved after December 31, 2026. 

Subject to the terms and conditions of the merger agreement, all contingent consideration would be paid in cash and stock at the 
discretion of the Company, subject to certain limitations, with the maximum number of shares that may be issued after closing limited 
to 6,322, representing total shares that may be issued in connection with the merger of 7,021 less 699 shares paid at closing. The 
maximum contingent consideration payable by AtriCure will not exceed $260,000. 

The Company measures contingent consideration liabilities using unobservable inputs by applying the probability-weighted 
scenario method, an income approach. Various key assumptions, such as the probability and timing of achievement of the agreed 
milestones, are used in the determination of fair value of contingent consideration arrangements and are not observable in the market, 
thus representing a Level 3 measurement within the fair value hierarchy.  

The recurring Level 3 fair value measurements of the contingent consideration liabilities include the following significant 

inputs as of December 31, 2020:

Contingent consideration liabilities are periodically remeasured. Changes in the discount rate, time until payment and 

probabilities of payment may result in materially different fair value measurements. A decrease in the discount rate would result in a 
higher fair value measurement, while a decrease in the probability of payment would result in a lower fair value measurement. 
Movement in the forecasted timing of achievement to later in the milestone periods also causes a decrease in the fair value 
measurement. Subsequent revisions in key assumptions, which impact the estimated fair value of contingent consideration liabilities 
are recorded in selling, general and administrative expenses. The nContact contingent consideration was remeasured to $0 during 2020 
and expired as of December 31, 2020 without meeting the regulatory milestone. The fair value of the SentreHEART contingent 
consideration was remeasured during 2020 resulting in an increase in fair value due to accretion and changes in estimates related to 
the forecasted timing of achievement of the milestones. 

The following table represents the Company’s Level 3 fair value measurements using significant other unobservable inputs for 

acquisition-related contingent consideration for each of the years ended December 31:

5. BUSINESS COMBINATIONS 

On August 13, 2019, the Company acquired 100% of the outstanding equity interests of SentreHEART. Founded in 2005 and 

based in Redwood City, California, SentreHEART developed innovative technology for remote delivery of a suture for closure of 
anatomic structures including the left atrial appendage (LAA). This technology is currently being studied in the aMAZE IDE clinical 
trial, an FDA-approved, prospective, multicenter, randomized controlled trial. The objective of the aMAZE IDE trial is to demonstrate 
that the LARIAT® device for LAA closure, plus a Pulmonary Vein Isolation (PVI) ablation, will lead to a reduced incidence of 
recurrent Afib compared to PVI alone. Management believes the acquisition of SentreHEART will significantly expand the 
Company’s addressable markets with a product designed for electrophysiologists, and the acquisition of SentreHEART deepens the 
Company’s commitment to provide the broadest possible offering of ablation and LAA management solutions to patients and 
customers. 

The total consideration paid to SentreHEART’s former shareholders at the acquisition date was $18,008 in cash and 699 shares 

of AtriCure common stock valued at approximately $20,307. The cash paid at acquisition was subject to adjustment for net working 
capital balances outside of a specified range, resulting in a $768 adjustment received by the Company in November 2019. The merger 
agreement also provides for the Company to pay contingent consideration to former shareholders of SentreHEART if specified 
milestones are met related to the aMAZE IDE clinical trial, including PMA approval and reimbursement for the therapy involving 
SentreHEART’s devices. In connection with the acquisition of SentreHEART, fair value of $171,300 was recorded for the 
SentreHEART contingent consideration. See Note 3 for further details regarding the SentreHEART acquisition-related contingent 
consideration. Subject to the terms and conditions of the merger agreement, all contingent consideration would be paid in cash and 
stock at the discretion of the Company, subject to certain limitations, including the total number of shares that may be issued in 
connection with the merger. The maximum contingent consideration payable by AtriCure will not exceed $260,000. 

The Company accounted for the acquisition in accordance with ASC 805, “Accounting for Business Combinations”. The assets 

acquired, liabilities assumed and the estimated contingent consideration obligations are recorded at their respective fair values as of 
the date of acquisition. The process of estimating fair values of identifiable assets, certain intangible assets and assumed liabilities 
requires significant assumptions and estimates. The judgments used to determine the fair value assigned to each class of assets 
acquired and liabilities assumed, as well as asset lives, can materially impact the amounts recorded and the Company’s results of 
operations.

The fair value of the contingent consideration liabilities was determined by applying the probability-weighted scenario method. 

Key assumptions in the valuation of the contingent consideration liabilities are based on management’s judgment and estimates and 
include the probability of achievement of each of the milestones, timing of achievement and discount rates, reflecting the inherent 
risks of achieving the respective milestones. Most assumptions are not observable in the market, and thus represent a Level 3 
measurement within the fair value hierarchy. See Note 3 for discussion of unobservable inputs. 

The following table summarizes the fair values of the assets acquired and the liabilities assumed based on the information that 

was available as of the acquisition date:

During the measurement period, the Company recorded adjustments for the fair value of consideration transferred, including 

settlement of working capital, and the evaluation of certain tax attributes. Net deferred tax assets of $20,590 and offsetting valuation 
allowances were also recognized at the acquisition date for the future tax consequences attributable to differences between the above 
financial statement carrying amounts of existing assets and liabilities and their respective tax bases and acquired operating loss and tax 
credit carryforwards of SentreHEART. At acquisition, SentreHEART had approximately $184,036 of federal and state net operating 
loss carryforwards, which begin to expire in 2026 and $37,906 of federal net operating loss carryforwards which have no expiration as 
a result of the Tax Reform Act. A portion of the net operating loss carryforwards are subject to certain limitations under Internal 
Revenue Code Section 382. The Company recorded a full valuation allowance against the net deferred tax assets at acquisition. The 
goodwill recorded is not deductible for tax purposes.

PMA approval from the in-process aMAZE IDE clinical trial and is accounted for as an indefinite-lived intangible asset until 
completion or abandonment of the project. 

The Company recorded the excess of the aggregate purchase price over the estimated fair values of the identifiable net assets 

acquired as goodwill. Goodwill is primarily attributable to the benefits the Company expects to realize by enhancing its product 
offering and addressable markets, thereby contributing to an expanded revenue base. As discussed in Note 1, the Company accounts 
for goodwill in a single reporting unit representing the Company as a whole.  

The 2019 operating results of SentreHEART, including $1,280 of appendage management revenue and $8,505 of net loss, are 

included in the Consolidated Statements of Operations and Comprehensive Loss beginning August 14, 2019. The Consolidated 
Balance Sheet as of December 31, 2019 reflects the acquisition of SentreHEART. The Company recognized approximately $138 and 
$3,978 of acquisition-related costs in the years ended December 31, 2020 and 2019, consisting of legal, audit, tax and other due 
diligence expenses. Acquisition-related costs are included in selling, general and administrative expenses. 

The following supplemental pro forma information presents the financial results of the Company for the twelve months ended 

December 31, 2019 and 2018 as if the acquisition of SentreHEART had occurred on January 1, 2018.

Certain pro forma adjustments have been made when calculating the amounts above to reflect the impact of the purchase 
transaction, primarily consisting of the exclusion of SentreHEART’s interest expense incurred on debt paid off or converted to equity 
in the acquisition, exclusion of fair value adjustments for SentreHEART’s derivative liabilities and preferred warrants settled as part 
of the acquisition, adjustments for amortization of intangible assets with determinable lives and exclusion of contingent consideration 
remeasurement. The Company also eliminated transaction expenses incurred by both AtriCure and SentreHEART. The supplemental 
pro forma information has been prepared for comparative purposes and does not purport to be indicative of what would have occurred 
had the acquisition been made on January 1, 2018, nor is it indicative of any future results. The pro forma information does not 
include any adjustments for potential revenue enhancements, cost synergies or other operating efficiencies that could result from the 
acquisition.

Credit Facility. The Company has a Loan and Security Agreement (Loan Agreement) with Silicon Valley Bank (SVB), which 

includes a $60,000 term loan and $20,000 revolving line of credit. The total combined term loan and revolving line of credit 
outstanding under the Loan Agreement cannot exceed $70,000 at any time prior to SVB’s consent. The term loan and revolving credit 
facility both mature or expire, as applicable, on August 1, 2024.  

Principal payments of the term loan are to be made ratably commencing March 1, 2021 through the loan’s maturity date. If the 
Company meets certain conditions, as specified by the Loan Agreement, the commencement of term loan principal payments may be 
deferred by an additional six months. The term loan accrues interest at the greater of the Prime Rate or 5.00%, plus 0.75% and is 
subject to an additional 3.00% fee on the $60,000 term loan principal payable at maturity or upon acceleration or prepayment of the 
term loan. The Company is accruing the 3.00% fee over the term of the Loan Agreement, with $495 accrued in the outstanding loan 
balance as of December 31, 2020. Additionally, the unamortized original financing costs related to the term loan of $393 are netted 
against the outstanding loan balance in the Consolidated Balance Sheets and are amortized ratably over the term of the Loan 
Agreement.  

The revolving line of credit is subject to an annual facility fee of 0.15% of the revolving line of credit, and any borrowings 

thereunder bear interest at the greater of the Prime Rate or 5.00%. Borrowing availability under the revolving credit facility is based 
on the lesser of $20,000 or a borrowing base calculation as defined by the Loan Agreement. As of December 31, 2020, the Company 
had no borrowings under the revolving credit facility and had borrowing availability of $8,750. Financing costs related to the 
revolving line of credit are included in other assets in the Consolidated Balance Sheets and amortized ratably over the twelve-month 
period of the annual fee.  

On April 29, 2020, the Company and SVB entered into an amendment to the Loan Agreement which modified a covenant 

related to the Company’s liquidity ratio through the third quarter 2020 testing date and increased the early termination fees for both 
the term loan and revolving line of credit. The amendment was treated as a debt modification.  

On February 8, 2021, the Company and SVB entered into an amendment to the Loan Agreement which modified conditions 

which allow the Company to request to defer the term loan principal payments an additional six months, commencing in September 
2021, if such conditions were satisfied. Additionally, the covenant reporting requirements were modified. The amendment was treated 
as a debt modification. Subsequent to the amendment, the conditions were satisfied by the Company and the Company requested such 
deferral. As a result, borrowings outstanding under the existing term loan agreement have been classified to reflect the deferral of 
principal payments in the Consolidated Balance Sheet as of December 31, 2020. 

Future principal payments of long-term debt are projected as follows: 

2021 
2022 
2023 
2024 

Total long-term debt, of which $6,667 is current and $53,333 is noncurrent

The Loan Agreement also provides for certain prepayment and early termination fees, as well as establishes a minimum 

liquidity covenant and dividend restrictions, along with other customary terms and conditions. Specified assets have been pledged as 
collateral.

11. LEASES 

The Company has operating and finance leases for corporate offices, manufacturing and warehouse facilities and computer 
equipment. The Company’s leases have remaining lease terms of one year to ten years. Options to renew or extend leases beyond their 
initial term have been excluded from measurement of the ROU assets and lease liabilities for the majority of leases as exercise is not 
reasonably certain.  

The weighted average remaining lease term and the discount rate for the reporting periods is as follows:

12. COMMITMENTS AND CONTINGENCIES 

Royalty Agreements. The Company has royalty agreements in place with terms that include payment of royalties of 3% to 5% 

of specified product sales. One royalty agreement remains in effect through 2025, while the other agreement remains in effect the later 
of 2023 or until expiration of the underlying patents or patent applications. Parties to the royalty agreements have the right at any time 
to terminate the agreement immediately for cause. Royalty expense of $2,596, $2,892 and $2,715 was recorded as part of cost of 
revenue for the years ended December 31, 2020, 2019 and 2018.  

Purchase Agreements. The Company enters into standard purchase agreements with certain vendors in the ordinary course of 

business, generally with terms that allow cancellation. 

Legal. The Company may, from time to time, become a party to legal proceedings. Such matters are subject to many 
uncertainties and to outcomes of which the financial impacts are not predictable with assurance and that may not be known for 
extended periods of time. When management has assessed that a loss is probable and an amount can be reasonably estimated, the 
Company records a liability.  

The Company received a Civil Investigative Demand (CID) from the U.S. Department of Justice (USDOJ) in December 2017 

stating that it is investigating the Company to determine whether the Company has violated the False Claims Act, relating to the 
promotion of certain medical devices related to the treatment of atrial fibrillation for off-label use and submitted or caused to be 
submitted false claims to certain federal and state health care programs for medically unnecessary healthcare services related to the 
treatment of atrial fibrillation. The CID covers the period from January 2010 to December 2017 and requires the production of 
documents and answers to written interrogatories. The Company had no knowledge of the investigation prior to receipt of the CID. 
The Company maintains rigorous policies and procedures to promote compliance with the False Claims Act and other applicable 
regulatory requirements. The Company provided the USDOJ with documents and answers to the written interrogatories and is

cooperating with its investigation. However, the Company cannot predict when the investigation will be resolved, the outcome of the 
investigation or its potential impact on the Company.  

The Company acquired nContact Surgical, Inc. pursuant to a merger agreement dated October 4, 2015. The merger agreement 
provides for contingent consideration or “earnout” to be paid upon attaining specified regulatory approvals and clinical and revenue 
milestones. The merger agreement’s earnout provisions required the Company to deliver periodic earnout reports to a designated 
representative of former nContact stockholders. In response to the reports delivered in and after February 2018, the Company received 
letters from representatives purporting to serve as “earnout objection statements” (as that term is defined in the merger agreement) and 
claim that for purposes of determining the commercial milestone payment, the Company should be including revenues of certain 
additional items and products that the Company has not included in its earnout statements. During February 2021, the Company 
entered into a settlement agreement with the former nContact stockholders requiring payment of $6,000. The Company has recorded 
the $6,000 settlement as a component of current liabilities as of December 31, 2020 as the underlying cause occurred prior to 
December 31, 2020. 

13. REVENUE 

Revenue is generated primarily from the sale of medical devices. The Company recognizes revenue in an amount that reflects 

the consideration the Company expects to be entitled to in exchange for those devices when control of promised devices is transferred 
to customers. At contract inception, the Company assesses the products promised in its contracts with customers and identifies a 
performance obligation for each promise to transfer to the customer a product that is distinct. The Company’s devices are distinct and 
represent performance obligations. These performance obligations are satisfied, and revenue is recognized at a point in time upon 
shipment or delivery of products. Sales of devices are categorized as follows: open ablation, minimally invasive ablation, appendage 
management and valve tools. Shipping and handling activities performed after control over products transfers to customers are 
considered activities to fulfill the promise to transfer the products rather than as separate promises to customers. Revenue includes 
shipping and handling revenue of $1,192, $1,485 and $1,236 in 2020, 2019 and 2018. 

Products are sold primarily through a direct sales force and through distributors in certain international markets. Terms of sale 
are generally consistent for both end-users and distributors, except that payment terms are generally net 30 days for end-users and net 
60 days for distributors, with limited exceptions. The Company does not maintain any post-shipping obligations to customers. No 
installation, calibration or testing of products is performed by the Company subsequent to shipment in order to render products 
operational.  

Significant judgments and estimates involved in the Company’s recognition of revenue include the estimation of a provision for 

returns. We estimate the provision for sales returns and allowances using the expected value method based on historical experience 
and other factors that we believe could impact our expected returns, including defective or damaged products and invoice adjustments. 
In the normal course of business, the Company generally does not accept product returns unless a product is defective as 
manufactured. The Company does not provide customers with the right to a refund.  

The Company expects to be entitled to the total consideration for the products ordered by customers as product pricing is fixed 

according to the terms of customer contracts and payment terms are short. Payment terms fall within the one-year guidance for the 
practical expedient which allows the Company to forgo adjustment of the promised amount of consideration for the effects of a 
significant financing component. The Company excludes taxes assessed by governmental authorities on revenue-producing 
transactions from the measurement of the transaction price.  

Costs associated with product sales include commissions and royalties. Considering that product sales are performance 

obligations in contracts that are satisfied at a point in time, commission expense associated with product sales and royalties paid based 
on sales of certain products is incurred at that point in time rather than over time. Therefore, the Company applies the practical 
expedient and recognizes commissions and royalties as expense when incurred because the expense is incurred at a point in time and 
the amortization period is less than one year. Commissions are recorded as selling expense and royalties are recorded as cost of 
revenue. 

See Note 18 for disaggregated revenue by geographic area and by product category.

14. INCOME TAXES  

The Company files federal, state, local and foreign income tax returns in jurisdictions with varying statutes of limitations. 

Income taxes are computed using the asset and liability method in accordance with FASB ASC 740, “Income Taxes”, under which 
deferred income taxes are provided for the temporary differences between the financial reporting basis and the tax basis of the 
Company’s assets and liabilities. Deferred taxes are measured using provisions of currently enacted tax laws. A valuation allowance 
against deferred tax assets is recorded when it is more likely than not that such assets will not be fully realized. The Company has 
recorded a valuation allowance against substantially all its net deferred tax assets as it is more likely than not that the benefit of the 
deferred tax assets will not be recognized in future periods.  

The Company’s provision for income taxes for each of the years ended December 31 is as follows:  

Current Tax Expense

The Company’s pre-tax book loss for domestic and international operations was $(43,218) and $(4,823) for 2020, $(28,002) and 

$(6,993) for 2019 and $(13,443) and $(7,468) for 2018.  

The Company had undistributed earnings of foreign subsidiaries of approximately $235 at December 31, 2020. The Company 

does not consider these earnings as permanently reinvested and has determined that no current and deferred taxes are required on such 
amounts. 

Federal, state and local tax returns of the Company are routinely subject to examination by various taxing authorities. Federal 

income tax returns for periods beginning in 2017 are open for examination. Generally, state and foreign income tax returns for periods 
beginning in 2016 are open for examination. However, taxing authorities have the ability to adjust net operating loss and tax credit 
carryforwards from years prior to these periods. The Company has not recognized certain tax benefits because of the uncertainty of 
realizing the entire value of the tax position taken on income tax returns upon review by the taxing authorities.  

A reconciliation of the change in federal and state unrecognized tax benefits for 2020, 2019 and 2018 is presented below: 

Balance at the beginning of the year  
Increases (decreases) for prior year tax positions  
Increases (decreases) for current year tax positions 
Increases (decreases) related to settlements  
Decreases related to statute lapse  
Balance at the end of the year

For 2019, the Company’s increase for prior year tax positions relates to uncertain income tax benefits assumed pursuant to the 

SentreHEART acquisition. Historically, the Company did not have any interest and penalties accrued for unrecognized income tax 
benefits as a result of offsetting net operating losses. The Company has accrued interest and penalties associated with uncertain 
income tax benefits assumed pursuant to the SentreHEART acquisition as of December 31, 2019, and recognized interest and 
penalties within income tax expense. The amount is not significant.  

There are no amounts included in the balance of unrecognized tax benefits at December 31, 2018 that, if recognized, would 

affect the effective tax rate. The balance of unrecognized tax benefits at December 31, 2020 and 2019 includes $1,798 and $1,777 of 
tax benefits that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes and valuation allowance. 
The Company does not expect that its unrecognized tax benefits for research credits will significantly change within twelve months of 
December 31, 2020.  

15. CONCENTRATIONS 

During 2020, 2019 and 2018, approximately 10.8%, 12.0% and 10.8% of the Company’s total net revenue was derived from its 

top ten customers. During 2020, 2019 and 2018 no individual customer accounted for more than 10% of the Company’s revenue.  

As of December 31, 2020 and 2019, 13.0% and 16.5% of the Company’s total accounts receivable balance was derived from its 

top ten customers. No individual customer accounted for more than 10% of the Company’s accounts receivable as of December 31, 
2020 and 2019.

The Company maintains cash and cash equivalents balances at financial institutions which at times exceed FDIC limits. As of 

December 31, 2020, $41,694 of the cash and cash equivalents balance was in excess of the FDIC limits. 

16. EMPLOYEE BENEFIT PLANS 

The Company sponsors the AtriCure, Inc. 401(k) Plan (401(k) Plan), a defined contribution plan covering substantially all U.S. 

employees of the Company. Eligible employees may contribute pre-tax annual compensation up to specified maximums under the 
Internal Revenue Code. During 2020, 2019 and 2018, the Company made matching contributions of 50% on the first 6% of employee 
contributions to the 401(k) Plan. The Company’s matching contributions expensed during 2020, 2019 and 2018 were $2,237, $1,915 
and $1,560. Additional amounts may be contributed to the 401(k) Plan at the discretion of the Company’s Board of Directors, 
however, no such discretionary contributions were made during 2020, 2019 or 2018. The Company also provides retirement benefits 
for employees of AtriCure Europe B.V. and other foreign subsidiaries. Total contributions to retirement plans for these employees 
were $244, $248 and $243 in 2020, 2019 and 2018. 

17. EQUITY COMPENSATION PLANS 

The Company has two share-based incentive plans: the 2014 Stock Incentive Plan (2014 Plan) and the 2018 Employee Stock 

Purchase Plan (ESPP). 

Stock Incentive Plan 

Under the 2014 Plan, the Board of Directors may grant incentive stock options to Company employees and may grant restricted 

stock awards or restricted stock units (collectively RSAs), nonstatutory stock options, performance share awards (PSAs) or stock 
appreciation rights to Company employees, directors and consultants. The administrator (the Compensation Committee of the Board 
of Directors) has the authority to determine the terms of any awards, including the number of shares subject to each award, the 
exercisability of the awards and the form of consideration. As of December 31, 2020, 12,899 shares of common stock had been 
reserved for issuance under the 2014 Plan and 1,932 shares were available for future grants.  

Stock options, restricted stock awards, and restricted stock units granted generally vest at a rate of 33.3% on the first, second 
and third anniversaries of the grant date. Stock options granted prior to 2018 under the 2014 Plan generally vest at a rate of 25% on the 
first anniversary date of the grant and ratably each month thereafter over the following three years. Restricted stock awards granted 
prior to 2018 generally vest between one year and four years from the date of grant. Stock options generally expire ten years from the 
date of grant. 

In 2012 the Company granted 450 performance options to its President and Chief Executive Officer pursuant to his Employment 

Agreement. The options expire ten years from the date of grant and vest in increments of 25 shares when the volume adjusted 
weighted average closing price of the common stock of the Company as reported by NASDAQ (or any other exchange on which the 
common stock of the Company is listed) for 30 consecutive days equals or exceeds each of $10.00 per share, $12.50 per share, $15.00 
per share, $17.50 per share, $20.00 per share, $25.00 per share, $30.00 per share, $35.00 per share and $40.00 per share. As of 
December 31, 2020, all of the performance options vested. A Monte Carlo simulation was performed to estimate the fair values, 
vesting terms and vesting probabilities for each tranche of options. Expense calculated using these estimates was recognized over the 
estimated vesting terms. As of December 31, 2017, compensation costs related to non-vested performance options were fully 
recognized. 

The Compensation Committee approved the grant of performance share awards to the Company’s Executive Leadership Team 
pursuant to the Company’s 2014 Plan. The form of award agreement for the PSAs (PSA Grant Form) provides, among other things, 
that each PSA that vests represents the right to receive one share of the Company’s common stock at the end of the performance 
period. With respect to the PSAs, the number of shares that vest and are issued to the recipient is based upon the Company’s 
performance as measured against the specified performance target at the end of the three-year performance period as determined by 
the Compensation Committee. Established threshold, target and maximum payout opportunities, which may range from 0% to 200% 
of the target amount, are used to calculate the number of shares that will be issuable when the award vests. Additionally, all or a 
portion of the PSAs may vest following a change of control or a termination of service by reason of death or disability (each as 
described in greater detail in the PSA Grant Form). The Company estimated the fair value of the PSAs based on its closing stock price 
on the grant date and will adjust compensation expense over the performance period based on its estimate of performance target 
achievement. 

In 2020, the Compensation Committee modified the methodology for measuring performance of the 2018, 2019, and 2020 

performance awards. As a result of the modification which impacted the vesting conditions and performance measures related to the 
awards, the incremental compensation cost resulting from the modification is $4,162, of which $569 is reflected in the year ended 
December 31, 2020.

The total intrinsic value of options exercised during the years ended December 31, 2020, 2019 and 2018 was $29,594, $1,985 

and $5,343. As a result of the Company’s full valuation allowance on its net deferred tax assets, no tax benefit was recognized related 
to the stock option exercises. The exercise price per share of each option is equal to the fair market value of the underlying share on 
the date of grant. For 2020, 2019 and 2018, $10,835, $1,202 and $6,012 in cash proceeds were included in the Consolidated 
Statements of Cash Flows as a result of the exercise of stock options. The total fair value of restricted stock vested during 2020, 2019 
and 2018 was $34,200, $23,479 and $11,864. The Company issues registered shares of common stock to satisfy stock option exercises 
and restricted stock grants.

ATRICURE, INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 
(In Thousands, Except Per Share Amounts) 

As of December 31, 2020 there was $18,561 of unrecognized compensation costs related to non-vested stock options and 

restricted stock arrangements ($1,075 relating to stock options and $17,486 relating to restricted stock). This cost is expected to be 
recognized over a weighted-average period of 2.0 years for stock options and 1.7 years for restricted stock. As of December 31, 2020 
there was $6,940 of unrecognized compensation costs related to non-vested performance share awards, and this cost is expected to be 
recognized over a weighted-average period of 1.6 years. 

In calculating compensation expense, the fair value of restricted stock awards, restricted stock units and performance share 
awards is based on the market value of the Company’s stock on the date of the awards or subsequent modification (as applicable). The 
fair value of the options is estimated on the grant date using the Black-Scholes model including the following assumptions: 

Range of risk-free interest rate 
Range of expected life of stock options (years) 
Range of expected volatility of stock 
Weighted-average volatility

The Company’s estimate of volatility is based solely on the Company’s trading history over the expected option life. The risk-

free interest rate assumption is based upon the U.S. treasury yield curve at the time of grant for the expected option life. The Company 
estimates the expected terms of options using historical employee exercise behavior.  

Based on the assumptions noted above, the weighted average estimated grant date fair value per share of the stock options, 

restricted stock awards and performance share awards granted for 2020, 2019 and 2018 was as follows:

DISCLOSURE  

None.  

ITEM 9A.  CONTROLS AND PROCEDURES 

Evaluation of Disclosure Controls and Procedures  

The Company’s management, with the participation of the President and Chief Executive Officer (the Principal Executive 

Officer) and Chief Financial Officer (the Principal Accounting and Financial Officer), has evaluated the effectiveness of the 
Company’s disclosure controls and procedures as defined in Rule 13(a) – 15(e) of the Securities Exchange Act of 1934 (Exchange 
Act), as of the end of the period covered by this report. Based on this evaluation, we concluded that, as of the end of the period 
covered by this report, our disclosure controls and procedures were effective in providing reasonable assurance that information 
required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and 
reported within the time periods specified in the SEC’s forms and rules, and the material information relating to the Company is 
accumulated and communicated to management, including the President and Chief Executive Officer and Chief Financial Officer, as 
appropriate, to allow timely decisions regarding required disclosures. 

Control systems, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that control 

objectives are met. Because of inherent limitations in all control systems, no evaluation of controls can provide assurance that all 
control issues and instances of fraud, if any, within a company will be detected. Additionally, controls can be circumvented by 
individuals, by collusion of two or more people or by management override. Over time, controls can become inadequate because of 
changes in conditions or the degree of compliance may deteriorate. Further, the design of any system of controls is based in part upon 
assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals 
under all future conditions. Because of the inherent limitations in any cost-effective control system, misstatements due to errors or 
fraud may occur and not be detected.  

Changes in Internal Control over Financial Reporting  

In the ordinary course of business, we routinely enhance our information systems by either upgrading current systems or 
implementing new ones. There were no changes in our internal control over financial reporting that occurred during the three months 
ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial 
reporting.  

Management’s Annual Report on Internal Control Over Financial Reporting  

The management of the Company is responsible for establishing and maintaining adequate internal control over financial 
reporting. The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting 
principles generally accepted in the United States of America. Internal control over financial reporting includes policies and 
procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and 
expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; 
and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the 
Company’s assets that could have a material effect on the financial statements. The Company’s management assessed the 
effectiveness of the Company’s internal control over financial reporting as of December 31, 2020. No matter how well designed, 
because of inherent limitations in all control systems, internal control over financial reporting may not prevent or detect misstatements 
should they occur. 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 control procedures may deteriorate. In 
making this assessment, the Company’s management used the criteria set forth by the Committee of Sponsoring Organizations of the 
Treadway Commission in Internal Control-Integrated Framework (2013). Based on such assessment, management has concluded that 
the Company’s internal control over financial reporting was effective as of December 31, 2020.  

Deloitte & Touche LLP, the Company’s independent registered public accounting firm, has audited the consolidated financial 
statements included in this Annual Report on Form 10-K and, as part of its audit, has issued an attestation report on the effectiveness 
of the Company’s internal control over financial reporting. The attestation report can be found on the following page as part of this 
Item 9A.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  

To the stockholders and the Board of Directors of  
AtriCure, Inc. 
Mason, Ohio 

Opinion on Internal Control over Financial Reporting 

We have audited the internal control over financial reporting of AtriCure, Inc. and subsidiaries (the “Company”) as of December 31, 
2020, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective 
internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control — Integrated 
Framework (2013) issued by COSO. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated financial statements as of and for the year ended December 31, 2020, of the Company and our report dated 
February 26, 2021, expressed an unqualified opinion on those financial statements. 

Basis for Opinion 

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

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

Definition and Limitations of Internal Control over Financial Reporting 

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

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

Board Committees 

Effective February 25, 2021, the Company’s Board of Directors re-constituted its committees as follows: 

Audit: Sven A. Wehrwein (Chair), Daniel P. Florin, Mark R. Lanning, Regina E. Groves 
Compensation: B. Kristine Johnson (Chair), Mark A. Collar, Mark R. Lanning, Karen N. Prange

Amendments to Performance Share Awards 

Effective as of February 25, 2021, pursuant to approval and direction from the Compensation Committee, the Company 
amended certain terms of performance share awards (PSAs) granted to active named executive officers and certain other executive 
employees (collectively, the “Executive Leadership Team”) in 2018, 2019 and 2020 pursuant to the Company’s 2014 Plan.  

The award agreements for the PSAs provide, among other things, that each PSA that vests represents the right to receive one 

share of the Company’s common stock at the end of the performance period. The number of shares that vest and are issued to the 
recipient is based upon the Company’s performance as measured against the specified performance target (the Company’s revenue 
compound annual growth rates (CAGR) at the end of the three-year performance period).  

The amendments modify the methodology for calculating the Company’s three year revenue growth as follows: (i) one-year 
revenue growth will be calculated for each year in the performance cycle; (ii) with respect to the calculation of revenue growth for 
each year in the performance cycle, if the Company achieves a growth rate less than the “Threshold” Performance Goal, then a 0% 
growth rate shall be substituted in place of such actual rate for the applicable year in the performance cycle; (iii) with respect to the 
calculation of revenue growth for each year in the performance cycle, if the Company achieves a growth rate greater than the 
“Maximum” Performance Goal, then the “Maximum” growth rate identified in the Performance Share Award Agreement shall be 
substituted in place of such actual rate for the applicable year in the performance cycle; (iv) all three years in the applicable 
performance cycle shall be averaged to provide revenue growth for purposes of determination vesting; and (v) in no event shall 
payouts under such PSA agreements exceed the “Target” amount originally identified in the applicable PSA agreements. 

With respect to the PSAs granted in 2018 to current active members of the Executive Leadership Team, the Compensation 
Committee applied the calculation methodology described above to determine that the 2018 PSAs vest at the 93% payout level. With 
respect to the PSAs granted in 2019 and 2020, on February 25, 2021 the Company executed amendments to the PSA agreements for 
the 2019 and 2020 awards reflecting the modified calculation methodology described above. The form of amendment to the PSA 
agreements is filed herewith as Exhibit 10.19. The description of these amendments does not purport to be complete and is qualified in 
its entirety by reference to such exhibit. 

The Compensation Committee took the actions described above due to developments related to the COVID-19 pandemic. The 

challenging environment resulting from the COVID-19 pandemic materially and adversely impacted the Company’s addressable 
markets, as cardiac surgery and elective procedures were either significantly reduced or indeterminately deferred during the pandemic 
in order to preserve resources for COVID-19 patients and caregivers and to protect patients from potential exposure to COVID-19.  
Consequently, the achievement of any revenue growth was rendered extremely unlikely. Management expects that the contraction in 
addressable markets will continue to decrease demand for the Company’s products and adversely impact the Company’s revenue and 
financial condition while the pandemic persists. 

Recognizing the significant adverse impact of COVID-19 on the Company’s opportunity to grow revenue, which is the single 

metric used to measure performance under the outstanding awards, the Compensation Committee determined that the opportunities to 
achieve the performance thresholds for the PSA agreements entered into in 2018, 2019 and 2020 had all been directly and 
significantly impacted. The Compensation Committee also noted that while the pandemic had a direct and material impact on the 
Company’s 2020 revenue, the Company’s historical revenue growth outperformed the target revenue metrics. Further, despite the lack 
of opportunity to achieve revenue growth as a result of the pandemic, the Compensation Committee believes that the Executive 
Leadership team has been successful in executing strategic initiatives and has driven meaningful value for shareholders. The 
Compensation Committee views the efforts of the Executive Leadership Team throughout the performance periods as critical to the 
advancement of key Company initiatives, the prioritization of the safety and retention of Company employees and the Company’s 
execution of shareholder value-driving activity.

2021 Performance Share Award Grants

PSAs granted to the Executive Leadership Team.  

The award agreements for the PSAs provide, among other things, that each PSA that vests represents the right to receive one 

share of the Company’s common stock at the end of the performance period. With respect to the PSAs, the number of shares that vest 
and are issued to the recipient is based upon the Company’s performance with respect to two measurements, each of which is equally 
weighted at the end of the three-year performance period as determined by the Compensation Committee: (i) the Company’s revenue 
compound annual growth rates (CAGR); and (ii) relative total shareholder return (TSR). TSR will be measured against the Nasdaq 
Health Care Index constituents and will be measured as the 20-trading-day average stock price prior to the end of the performance 
period over the 20-trading-day average stock price prior to the beginning of the performance period. Established threshold, target and 
maximum payout opportunities, which may range from 0% to 200% of the target amount, are used to calculate the number of shares 
that will be issuable when the award vests. The CAGR and TSR component payouts will be determined independently and added 
together for the total payout for the three-year performance period, subject to the maximum(s) defined in the PSA agreements. All or a 
portion of the 2021 PSAs may vest following a change of control or a termination of service by reason of death or disability. 

The Compensation Committee granted target value of 2021 PSAs to the Company’s named executive officers as follows:
