This Form 10-K, including the sections titled “Management’s Discussion and Analysis of Financial Condition and 
Results of Operations”, “Risk Factors” and “Quantitative and Qualitative Disclosures about Market Risk” contains 
forward-looking statements regarding our future performance. All forward-looking information is inherently uncertain and 
actual results may differ materially from assumptions, estimates or expectations reflected or contained in the forward-
looking statements as a result of various factors, including those set forth under “Risk Factors” and elsewhere in this 
Form 10-K. There may be additional risks of which we are not presently aware or that we currently believe are immaterial 
which could have an adverse impact on our business. Forward-looking statements often address our expected future 
business, financial performance, financial condition and results of operations, and often contain words such as “intends,” 
“estimates,” “anticipates,” “hopes,” “projects,” “plans,” “expects,” “drives,” “seek,” “believes,” “see,” “focus,” 
“should,” “will,” “would,” “opportunity,” “outlook,” “could,” “can,” “may,” “future,” “predicts,” “target,” 
“potential,” "forecast," "trend," "might" and similar expressions and the negative versions of those words, and may be 
identified by the context in which they are used. However, the absence of these words does not mean that a statement is not 
forward-looking. Forward-looking statements include, without limitation, statements that address activities, events, 
circumstances or developments that AtriCure expects, believes or anticipates will or may occur in the future, such as 
earnings estimates (including projections and guidance), other predictions of financial performance, launches by AtriCure 
of new products, developments with competitors and market acceptance of AtriCure’s products. Such statements are based 
largely upon current expectations of AtriCure. Any forward-looking statement speaks only as of the date made. Reliance 
should not be placed on forward-looking statements because they involve known and unknown risks, uncertainties and 
other factors which may cause actual results, performance or achievements to differ materially from those expressed or 
implied. Forward-looking statements are based on AtriCure’s expectations, experience and perception of current 
conditions, trends, expected future developments and other factors it believes are appropriate under the circumstances and 
are subject to numerous risks and uncertainties, many of which are beyond AtriCure’s control. In other words, these 
statements are not guarantees of future performance and inherently involve a wide range of risks and uncertainties that are 
difficult to predict. With respect to the forward-looking statements, we claim the protection of the safe harbor for forward-
looking statements contained in the Private Securities Litigation Reform Act of 1995. These forward-looking statements 
speak only as of the date of this Form 10-K. We describe risks and uncertainties that could cause actual results and events 
to differ materially in "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of 
Operations" and "Quantitative and Qualitative Disclosures About Market Risk" (Part II, Item 7A of this Form 10-K).

ITEM 1. BUSINESS
Overview
We are a leading innovator in treatments for atrial fibrillation (Afib), left atrial appendage (LAA) management and 
post-operative pain management. Afib is an irregular heartbeat, or arrhythmia, which affects over 59 million people 
worldwide and is a growing epidemic. It is the most common cardiac arrhythmia encountered in clinical practice and 
results in high utilization of healthcare services and significant cost burden. Patients often progress from being in Afib 
intermittently (paroxysmal) to being in Afib continuously (non-paroxysmal). The continuous Afib patient population 
includes early persistent Afib, which lasts seven days to 6 months, persistent Afib, which lasts 6 months to one year, and 
long-standing persistent Afib, which lasts longer than one year. It is estimated that over 4 million people in the United 
States currently suffer from long-standing persistent Afib. Afib often occurs in conjunction with other cardiovascular 
diseases, including hypertension, congestive heart failure, left ventricular dysfunction, coronary artery disease and valvular 
disease.
Our cardiac ablation and left atrial appendage management (LAAM) products are used by physicians during open-
heart and minimally invasive surgical procedures. In open-heart procedures, the patient is undergoing heart surgery for 
other conditions, such as a mitral or aortic valve repair or a coronary artery bypass, and our products are used by physicians 
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 surgical procedures using our ablation and 
LAAM products with catheter ablation performed by an electrophysiologist. 
Our pain management solutions are used by physicians to freeze nerves during cardiothoracic or thoracic surgical 
procedures. Recovery from cardiothoracic and thoracic surgery can be complicated and painful. Many surgeons use 
multiple pain management strategies that include oral delivery of opioid and non-opioid pain medications. Our cryoICE 
cryoSPHERE® probes for pain management (known as Cryo Nerve Block) provides temporary relief of post-operative 
pain, allowing the patient's body to heal after surgery while the nerves regenerate and sensation is regained. 
We sell our products to medical centers through our direct sales force in the United States, Germany, France, the 
United Kingdom, the Benelux region, Canada and Australia. We also sell our products through distributors who in turn sell 
our products to medical centers in other international markets. Our business is primarily transacted in U.S. Dollars; direct 
sales transactions outside the United States are transacted in Euros, British Pounds, Canadian Dollars or Australian Dollars.
Market Overview 
Afib is the most commonly diagnosed sustained cardiac arrhythmia, with over one million diagnoses annually in the 
United States alone. Afib is also 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 diagnosed when they seek treatment for an associated condition, such as a 
structural heart disease or stroke. 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. 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 globally as the world population ages. 
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, technological advancements have made surgical ablation more effective, 
repeatable and available to cardiac surgeons and electrophysiologists around the world. Societal guidelines from the 
Society of Thoracic Surgeons (STS), Heart Rhythm Society (HRS) and American Association of Thoracic Surgery (AATS) 
have Class I recommendations for concomitant surgical ablation, meaning that it is a “recommended” treatment for patients 
who have structural heart disease and Afib. Guidelines for the treatment of more serious forms of Afib for patients without 
structural heart disease have also been introduced in the past several years. In 2024, the European Society of Cardiology 
(ESC) released Guidelines for Management of Atrial Fibrillation developed in collaboration with the European Association 
of Cardio-Thoracic Surgery (EACTS), in which they upgraded LAAM to the highest Class 1 recommendation. During 
Table of Contents

2023, the American College of Cardiology (ACC), American Heart Association (AHA), American College of Clinical 
Pharmacy (ACCP) and HRS released Guidelines for Diagnosis and Management of Atrial Fibrillation, and upgraded 
LAAM to the highest recommendation of Class 1 and now include Hybrid AF™ Therapy as a Class 2 recommendation. 
These societal guidelines are reflective of the scientific evidence suggesting that surgical and hybrid 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 300,000 are potential candidates for surgical ablation using our products, as they have pre-operative 
Afib. Today, we estimate that less than 20% of those candidates are being treated with surgical ablation. Therefore, we 
believe that the market for our ablation products represents a significant growth opportunity.
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. In 2021, a large independent international randomized trial, Left Atrial Appendage Occlusion Study 
(LAAOS) III, demonstrated a significant reduction in strokes when the LAA was managed during cardiac surgery. 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 also believed to be significant. Due to 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 and 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 our AtriClip system represents a 
significant growth opportunity.
Many Afib patients without other underlying structural heart disease, especially those with more advanced forms of 
Afib, are symptomatic and experience conditions such as palpitations, breathlessness and drowsiness. These patients tend 
to be motivated to seek treatment to alleviate their symptoms. Patients who are symptomatic are often treated by an 
electrophysiologist using catheter ablation. Catheter ablation is considered a percutaneous procedure that does not require 
the opening of the chest; rather, catheters are inserted through a small puncture in the groin. In addition to catheter ablation, 
there are other treatment options for patients with Afib, including pharmacological therapy (anti-arrhythmic drugs) and 
implantable pacemakers. It is estimated that approximately 500,000 Afib patients are treated by catheter ablation every year 
in the United States, a number that is expected to grow well over 10% annually. While the majority of paroxysmal Afib 
patients treated by catheter ablation tend to experience freedom from Afib, less than a third of long-standing persistent 
patients treated by catheter ablation are cured of their Afib at one year, and it declines even more thereafter. Randomized, 
prospective, multi-center data from the CONVERGE™ IDE clinical trial, along with a number of other recent real-world 
studies performed by physician investigators, show that these long-standing persistent Afib patients can experience more 
than double the success rate by adding an ablation on the outside surface of the heart using our EPi-Sense® ablation system. 
Thus, we believe the EPi-Sense ablation system used as a minimally invasive or Hybrid AF therapy also represents a 
significant growth opportunity for the Company.
Thoracic surgery involving an incision through the ribcage, typically referred to as thoracotomy access, and 
cardiothoracic surgery can often result in significant post-operative pain and longer hospital recovery times as patients 
refrain from mobilizing their chest near the incision site. It is estimated that each year approximately 150,0000 thoracic 
procedures and approximately 250,000 cardiothoracic procedures are performed in the United States. Hospital recovery 
times can vary from two to fifteen days depending on the procedure, operative complications associated with the 
procedure, pain management protocol and other factors. Most surgeons will employ a multi-modal pain management 
protocol that includes various pain management techniques, including techniques such as epidural delivery of medication 
directly around the spinal cord, intravenous or oral delivery of opioid and non-opioid pain medications, or other strategies. 
More focused, local techniques include syringe injections between vertebrates and Cryo Nerve Block which uses cryogenic 
energy to ablate peripheral nerves, temporarily stopping the transmission of pain signals coming from the chest wall during 
surgery. The nerve “scaffolds” remain intact, allowing axons to regenerate and restore nerve function over time. Cryo 
Nerve Block can be delivered using our cryoICE cryoSPHERE probes, which are specifically designed for Cryo Nerve 
Block therapy. Depending on the degree of invasiveness, physicians and their nursing staff will take advantage of multiple 
ways of managing pain for their patients. In recent years, prescription narcotics, or opioids, have come under heavy 
scrutiny due to their potential for long-term dependency, overdose and possible death. 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 thoracic surgery patients develops an unhealthy post-procedural addiction to prescription 
narcotics, making alternative, non-opioid pain management modalities, such as Cryo Nerve Block, an increasingly 
important part of how physicians manage post-operative pain. We believe the market for our pain management ablation 
products represents a significant growth opportunity. Further, applications for Cryo Nerve Block outside of thoracic 
surgery use are being studied by physician investigators and represent future possible growth opportunities.

AtriCure Solutions and Products
We believe that we are currently the market leader in the surgical treatment of Afib and LAAM, and pioneers of the 
application of Cryo Nerve Block in cardiothoracic surgical procedures. We anticipate that substantially all our revenue for 
the foreseeable future will relate to products we currently sell or are in the process of developing. Our products enable 
cardiothoracic surgeons to perform surgical ablation procedures with faster, less invasive and less technically challenging 
approaches and clinically proven results. We have completed, and continue to invest in, clinical studies for the use of our 
ablation and LAAM products to treat Afib, reduce post-operative Afib, and prevent strokes. Leading cardiothoracic 
surgeons and electrophysiologists, including those who serve or who have served as consultants to us, have published 
results of preclinical 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 create scar tissue using radio frequency (RF) energy or 
cryogenic (cryo) modalities. Our ablation products are part of platforms, each consisting of disposable hand pieces which 
connect to either a RF generator or a cryo generator. We generally place this capital equipment with our direct customers 
and sell to our distributors.
Products for open and minimally invasive ablation:
•
Isolator® Synergy™ Clamps. Our Isolator Synergy Ablation System clamps are single-use disposable RF 
products with jaws that close in a parallel fashion. The system consists of the clamp and an RF generator. 
We sell multiple configurations of our Isolator Synergy clamps. The various configurations provide the 
user with options to address patient specific procedure requirements or anatomy; however, all the clamps 
provide consistent performance using the same core technology. The parallel closure evenly compresses 
tissue and evacuates the blood and fluids from the energy pathway to make the ablation more effective. The 
Isolator Synergy Ablation System has been studied in multiple FDA approved clinical trials, including the 
previously completed ABLATE clinical trial which supported a pre-market approval (PMA) in 2011, as 
well as the ongoing DEEP AF IDE and HEAL-IST clinical trials. 
Our Isolator Synergy Ablation System includes multiple configurations 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. Certain products within our Isolator Synergy clamp 
line are in compliance with the European Union Medical Device Regulations (EU MDR) and bear the CE 
mark for commercial distribution throughout the member states of the European Union (EU) and other 
countries that comply with or mirror EU MDR. These products are available for sale in a number of other 
countries globally. 
In 2022, we launched the EnCompass® clamp in the United States, following 510(k) clearance in 2021. The 
EnCompass clamp is indicated for cardiac soft tissue ablation and is designed to make concomitant surgical 
ablations more efficient and is expected to drive deeper penetration of cardiac surgery procedures. In 2024, 
we received 510(k) clearance for our most recent configuration of the Isolator Synergy platform, the 
EnCapture™ clamp, which has enhanced geometry and features to facilitate engagement with the intended 
cardiac tissue. 
•
Multifunctional Pens and Linear Ablation Devices. These devices are single-use disposable RF products 
that come in multiple configurations. Surgeons generally use one or more of our pen and linear devices in 
combination with Isolator Synergy clamps. Our pen and linear ablation devices are cleared for sale in the 
United States under FDA 510(k) clearances, with indications for the ablation of cardiac tissue and/or the 
treatment of cardiac arrhythmias. Certain configurations of our pen and linear ablation devices are also 
cleared or approved for sale outside of the United States.
Products for open ablation:
•
cryoICE Cryoablation System. The cryoICE® cryoablation system is used in both open ablation 
procedures and cryoanalgesia for post-operative pain management. The system consists of the cryoICE 
BOX generator along with a variety of single-use disposable probes. The primary differences between these 
cryoablation probes is the form of the tissue-contacting distal end. The various configurations of cryoICE 
devices enable the user to make linear ablations of varied length, providing the surgeon with options to 
address the specific procedural objectives. Surgeons may utilize the cryoICE devices in combination with 
Isolator Synergy clamps or independently.

Our cryoablation devices are cleared for sale in the United States under FDA 510(k) clearances, and are in 
compliance with EU MDR and bear the CE mark for commercial distribution throughout the member states 
of the EU and other countries that comply with or mirror EU MDR. These products are available for sale in 
a number of other countries globally. 
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. 
Products for minimally invasive ablation:
•
EPi-Sense Systems. The EPi-Sense Guided Coagulation System and the EPi-Sense ST® Guided 
Coagulation System utilize monopolar RF energy for the coagulation of tissue. The system consists of the 
device and an RF generator. Our EPi-Sense devices are single-use disposable ablation devices capable of 
intraoperative cardiac signal sensing and recording when connected to an external recording device.
Our EPi-Sense System was studied through the CONVERGE clinical trial and approved in 2021 by FDA 
for the treatment of patients with systemic, drug refractory, long-standing persistent Afib when augmented 
with an endocardial ablation catheter. Our EPi-Sense ST Guided Coagulation System was approved via 
PMA supplement in late 2022. Hybrid AF Therapy is the only FDA-approved minimally invasive 
procedure to treat patients with long-standing persistent Afib and represents a proven option for patients 
with this advanced disease. The EPi-Sense System is in compliance with EU MDR and bear the CE mark 
for commercial distribution throughout the member states of the EU and other countries that comply with 
or mirror EU MDR. This system is available for sale in a number of other countries globally.
In 2024, FDA granted 510(k) clearance for EPi-Ease™, our Hybrid access device to facilitate guide-wire 
delivery, vacuum application and endoscope insertion. 
Products for pain management:
•
cryoSPHERE probes. The cryoSPHERE probe is used to apply cryogenic energy to targeted intercostal 
peripheral nerves in the ribcage in order to provide temporary pain relief. This technique, called Cryo 
Nerve Block, is applied intraoperatively 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. Scientific data that has been published on the effects of Cryo Nerve Block therapy 
has generally shown a significant reduction in prescription of opioids, significantly reduced length of stay 
for patients in the hospital and reduced healthcare utilization costs. The cryoSPHERE probe is 510(k) 
cleared for managing pain by temporarily ablating peripheral nerves and is in compliance with EU MDR 
and bears the CE mark for commercial distribution throughout the member states of the EU and other 
countries that comply with or mirror EU MDR. 
During 2024, we launched two new cryoSPHERE probes for pain management in the United States. The 
cryoSPHERE®+ cryoablation probe leverages new technology that minimizes thermal loss by focusing 
energy at the ball tip, allowing for a reduction in freeze time by 25%. The cryoSPHERE MAX™ probe 
features a larger ball tip, designed to optimize Cryo Nerve Block therapy. The cryoSPHERE MAX probe 
reduces freeze times by 50% when compared to the first generation cryoSPHERE cryoablation probe, and 
over 30% when compared to the cryoSPHERE+ probe.
Products for appendage management:
•
AtriClip System. The AtriClip® LAA Exclusion System includes various combinations of an implantable 
device (AtriClip) coupled to a single-use disposable applier. The AtriClip device is designed to exclude the 
left atrial appendage by mechanically clamping the appendage from the outside of the heart. In addition to 
the risk of blood clots originating in the left atrial appendage, the left atrial appendage has also been shown 
to be a source of arrhythmias. The exclusion of the LAA eliminates blood flow between the left atrial 
appendage and the atrium while avoiding contact with circulating blood and provides electrical isolation 
benefits after placement. We believe that the AtriClip system is safer, more effective and easier to use than 
other techniques for permanently excluding the left atrial appendage. The device comes in two geometries: 
a rectangular configuration which encircles the targeted tissue and a “V” shape which allows for an 
alternative lateral access, and a variety of lengths which are matched to each patient's anatomy. The 
appliers come in multiple forms tailored to specific procedural needs depending on the type of surgery and 
how the surgeon is accessing the heart.

In the United States, 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 can see the heart directly, 
with or without assistance from a camera, endoscope or other appropriate viewing technologies. Certain 
products of our AtriClip LAA Exclusion System are in compliance with EU MDR and bear the CE mark 
for commercial distribution throughout the member states of the EU and other countries that comply with 
or mirror EU MDR. These products are available for sale in a number of other countries globally.
During 2024, we launched the newest generation AtriClip, the AtriClip® FLEX-Mini™ device, in the 
United States. The AtriClip FLEX-Mini sets a new standard as the smallest profile for a surgical LAA 
device on the market and builds upon the proven technology and clinical benefits of our AtriClip platform, 
with ease of use and design simplicity that offers enhanced access and increased visibility for physicians.
The AtriClip LAA Exclusion System is currently being evaluated under the Left Atrial Appendage 
Exclusion for Prophylactic Stroke Reduction (LeAAPS™) IDE clinical trial.
We sell additional products and enabling technologies that hold 510(k) approvals, and certain products are in 
compliance with EU MDR and bear the CE mark for commercial distribution. The LARIAT® System is a solution for soft-
tissue closure that includes a suture loop coupled to a single-use disposable applier. The Lumitip™ dissector is used by 
surgeons to separate tissues to provide access to key anatomical structures that are targeted for ablation. Other enabling 
technologies include our Glidepath™ guides for placement of our clamps, Subtle™ Cannula’s to support access for our 
EPi-Sense catheters and a line of reusable cardiac surgery instruments.
Business Strategy
We are passionately focused on healing the lives of patients affected by Afib and pain after surgery. Our strategy is 
to expand the treatment options for patients who suffer from Afib, have a high risk of stroke, may develop post-operative 
Afib, or who suffer from post-operative pain, through the continued development of our technologies and expansion of our 
product offerings, clinical science investments and global commercial expansion. The key elements of our strategy include:
New Product and Procedure Innovation. Our product development pipeline includes projects which extend and 
improve our existing products, as well as research and development projects for new technologies and new procedural 
techniques. We plan to continue to develop new and innovative products and procedures, including those that allow us to 
enter new markets or expand our growth in existing markets.
Investments in Clinical Science. We continue to invest in landmark clinical 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. We believe 
publication of additional scientific evidence, in addition to robust ongoing research activities, will ultimately create an 
increased demand for our products.
Build Physician and Societal Relationships. We have formed consulting relationships with cardiothoracic surgeons, 
cardiologists, electrophysiologists, stroke neurologists and thoracic surgeons who work with us to develop and evaluate our 
products. Additionally, we regularly form advisory boards made up of key opinion leaders in multiple specialties to provide 
input to our training and clinical programs. We are building these relationships along with extended care professionals such 
as nurse practitioners and advanced practice providers, 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 seven years, the Society for Thoracic Surgeons (STS), Heart Rhythm Society (HRS), American College of 
Cardiology (ACC), American Heart Association (AHA), American College of Clinical Pharmacy (ACCP), European 
Society of Cardiology (ESC) and European Association of Cardio-Thoracic Surgery (EACTS) have released new 
guidelines on the surgical treatment of Afib in both open-heart and minimally-invasive settings, as well as the management 
of the left atrial appendage in surgical procedures.
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. With the approval of the EPi-Sense 
System, we began programs to train physicians on the use of the EPi-Sense system in a hybrid approach to treating patients 
with long-standing persistent Afib. More recently, we have implemented multidisciplinary training programs focused on

the heart team approach for creating and growing an arrhythmia treatment program and managing post-operative pain. We 
believe these training and education programs have increased awareness about the surgical treatment of Afib, 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.
Evaluate Acquisition Opportunities. We expect to continue to be opportunistic with respect to acquisitions. We 
evaluate acquisition opportunities on a variety of factors, including product innovation, clinical differentiation and other 
strategic and financial criteria.
Research and Product Development
Our ongoing research and development activities support our business strategy to expand treatment options and 
increase awareness in our current markets, as well as enabling expansion into adjacent markets. We are engaged in 
developing and researching new and existing products or concepts, preclinical studies, clinical trials and other regulatory 
activities. We make significant investments in both product development and clinical science activities to drive the 
advancement and adoption of new therapies in the marketplace. 
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:
LeAAPS. In April 2022, FDA approved the protocol for the Left Atrial Appendage Exclusion for Prophylactic 
Stroke Reduction (LeAAPS) IDE clinical trial. The trial is designed to evaluate the effectiveness of prophylactic LAA 
exclusion using the AtriClip LAA Exclusion System for the prevention of ischemic stroke or systemic arterial embolism in 
cardiac surgery patients without pre-operative AF diagnosis who are at risk for these events. This prospective, multicenter, 
randomized trial evaluates safety at 30 days post-procedure to demonstrate no increased risk with LAA exclusion during 
cardiac surgery and effectiveness with a minimum follow-up of five years post procedure for all subjects. The trial provides 
for enrollment of up to 6,500 subjects at up to 250 sites worldwide. We enrolled our first patient in January 2023; site 
initiation and enrollment is ongoing and we expect to complete enrollment in 2025. 
HEAL-IST. In February 2022, FDA approved the protocol for the Hybrid Epicardial and Endocardial Sinus Node 
Sparing Ablation Therapy for Inappropriate Sinus Tachycardia (IST) clinical trial (HEAL-IST). The HEAL-IST clinical 
trial is designed to study the safety and efficacy of a hybrid sinus node sparing ablation procedure using the Isolator 
Synergy Surgical Ablation System for the treatment of symptomatic, drug refractory or drug intolerant IST. The trial is a 
prospective, multicenter, single arm trial that evaluates safety 30 days post-procedure and evaluates primary effectiveness 
of freedom from IST (as specified) at 12 months post-procedure. The trial provides for enrollment of up to 142 patients at 
up to 40 sites in the United States, United Kingdom and European Union. The first patient enrollment in the trial occurred 
in June 2022; site initiation and enrollment is ongoing.
CONVERGE. The CONVERGE IDE clinical trial proved the safety and efficacy of the EPi-Sense System 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. In April 2021, FDA granted PMA approval of the EPi-Sense System for treatment of 
symptomatic, drug-refractory, long-standing persistent atrial fibrillation, when augmented with an endocardial ablation 
catheter. We believe the Convergent procedure, or Hybrid AF therapy, provides the only compelling treatment option for a 
large and vastly underpenetrated population of long-standing persistent Afib patients. The CONVERGE trial demonstrated 
superiority in the hybrid therapy arm compared to endocardial catheter ablation alone. In patients diagnosed with long-
standing persistent Afib, the therapy arm showed a 29% absolute difference in efficacy at 12 months (78% relative 
improvement) and an absolute difference of 35% at 18 months (110% relative improvement). There was also a 33% 
absolute difference in Afib burden reduction in favor of the Hybrid AF therapy at 12 months, which increased to 37% at 18 
months. In April 2021, we also received approval from FDA to conduct the CONVERGE Post Approval Study (PAS). This 
study allows for 325 patients to be enrolled at up to 50 sites. Site initiation and enrollment in the CONVERGE PAS is 
ongoing. 
We have and will continue to invest in other clinical trials to validate the long-term results of procedures using our 
products and to support applications to regulatory agencies for expanded indications. The Company continues to perform 
long-term patient follow-up in multiple studies and plans to present results at 2025 meetings.

During the fourth quarter of 2023, the 12-month follow-up results of enrolled patients from the DEEP AF Pivotal 
study were presented at the American Heart Association meeting. The two-year DEEP outcomes poster has been 
accepted for presentation at the 2025 AF Symposium. The DEEP AF IDE pivotal trial evaluated 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 results from this single arm study demonstrated superior freedom from atrial arrhythmias 
for staged hybrid ablation compared to a pre-specified performance goal. 
The Company is conducting analyses of additional trial data for publication, future development activities, or possible 
evaluation of label expansions.
Sales, Marketing and Medical Education 
Our global sales and marketing efforts focus on educating physicians about our unique technologies and their clinical 
benefits. We only promote our products for uses described in their labeling as cleared or approved by relevant regulatory 
agencies, and 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 310 employees. We select our sales personnel based on their 
expertise, experience and reputation in the medical device industry and their knowledge of cardiac and thoracic 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 approximately 70 employees 
focused on our direct markets, such as Germany, France, the United Kingdom, the Benelux region, Canada and Australia. 
We also maintain a network of distributors who market and sell our products in Asia and South America, as well as certain 
countries in Europe. We continue to evaluate opportunities for further expansion into markets outside of the United States.
Competition
AtriCure has the only medical devices that are approved by FDA for treating long-standing persistent Afib: the 
Isolator Synergy Ablation, the first medical device to receive FDA approval for the treatment of persistent Afib in a 
concomitant setting, and the EPi-Sense System, which received FDA approval for standalone treatment of Afib with 
Hybrid AF Therapy. However, our industry is competitive, is subject to change and can be significantly affected by new 
product introductions and other activities of industry participants. We compete with other companies and divisions of 
companies that sell a single or limited number of competitive product lines or in certain geographies. Our primary 
competitor in the cardiac surgery market is Medtronic, plc, who provides surgical ablation products and LAAM devices 
used by physicians for the treatment of Afib and related conditions. For standalone treatment of Afib, several companies 
offer endocardial catheter devices that are commonly used by electrophysiologists. These catheter devices are FDA-
approved to treat the paroxysmal and persistent forms of Afib, but they are not FDA indicated and have not been studied 
for the treatment of long-standing persistent Afib. Since our Hybrid AF Therapy involves both epicardial and endocardial 
techniques, we believe these catheters are complementary to our business because our products improve treatment 
outcomes for patients with non-paroxysmal forms of Afib when combined with intracardiac catheter devices. 
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, although we are not aware of any ongoing FDA trials by other 
companies to study ablation of long-standing persistent Afib patients. We are aware of other companies developing 
technology for cardiac tissue ablation and appendage management. New product introductions, technological advances and 
regulatory clearances from competitors may impact the use of our products in cardiac procedures. In addition to the cardiac 
surgery market, we also consider competition within the post-operative pain market. Currently, we are not aware of other 
companies in the United States who are pursuing cryo nerve block therapies for thoracic surgery. There are other 
companies outside of the United States who market their devices for a similar therapy.

Third-Party Reimbursement
Reimbursement for health care services 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, primarily 
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 LAAM device is used during a concomitant open-heart procedure, 
Medicare’s hospital reimbursement is based upon the patient’s primary structural heart surgical procedure. In contrast, sole 
therapy minimally invasive ablation or surgical LAAM procedures typically are reimbursed under a general cardiac surgery 
or intracardiac procedure MS-DRG. We believe hospital reimbursement rates for sole therapy and concomitant therapy 
cardiac surgical ablation or surgical LAAM are adequate to cover the cost of our products even when multiple procedures 
are performed. Similar to surgical ablation for Afib or surgical LAAM, cryoablation performed for post-operative pain 
management is reimbursed as part of the primary procedure, open thoracic or cardiac surgery, MS-DRG. We believe 
hospital reimbursement rates are typically adequate in these situations.
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, as well as surgical LAAM. However, some providers utilize unlisted CPT codes to 
obtain reimbursement when no appropriate CPT code exists, such as Cryo Nerve Block ablation when used for post 
operative pain control.
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 provide private payors 
information on FDA labels and new published studies to support positive coverage policies. We also 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 policies may significantly reduce reimbursement for procedures using our medical 
devices or deny coverage for those procedures altogether. We are actively working to pursue market 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.
United States Regulation:
FDA regulations govern nearly all of the activities that we perform, or which 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. 
Table of Contents
9

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, real-world data, 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 by manufacturers of uses that are not within 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 within approved or cleared device labeling. 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 (GMP); 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 Quality System Regulations (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 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 (AdvaMed Code) 
Table of Contents
10

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 by incorporating its 
fundamental principles into our Global Health Care Compliance Manual and incorporated its principles in our compliance 
policies, 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. In addition, regulatory agencies and authorities can halt distribution within the country or otherwise take 
action in accordance with local laws.
AtriCure is a member of MedTech Europe, a voluntary trade association for the medical technology industry 
including diagnostics, medical devices and digital health. MedTech Europe and its members are committed to a high level 
of ethical business practices and have put in place strict guidelines to advise medical technology manufacturers on how to 
collaborate ethically with healthcare professionals (HCPs). These guidelines are set out in the MedTech Europe Code of 
Ethical Business Practice (MedTech Code), which regulates all aspects of the industry's relationships with HCPs and 
healthcare organizations (HCOs). It covers medical education and research and development. It also introduces an 
independent enforcement mechanism and transparency obligations. The Code sets clear and transparent rules for the 
industry's relationships with HCPs and HCOs, including company events, third-party organized events, arrangements with 
consultants, gifts, research and financial support to medical education. We have adopted the MedTech Code and 
incorporated its principles into our Global Health Care Compliance Manual, employee training programs and relationships 
with medical professionals. This manual also takes into account other global compliance principles as set forth in other 
international codes of ethics, such as the APAC Med Code of Ethical Conduct and AdvaMed China Code.
Global anti-bribery laws such as the US Foreign Corrupt Practices Act, the UK Anti-Bribery Act, and other similar 
laws apply in markets around the world. We have incorporated these principles into our compliance policies and Global 
Health Care Compliance Manual, training programs, and business practices.
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 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.
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 and other diseases and conditions.
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 
Table of Contents
11

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.
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 know-how 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.
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 our products are 
sterilized by third parties. Purchased components are often sourced from a single supplier, but alternatives to critical 
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 raw materials. To date, we 
have not experienced significant product availability or delay issues directly related to obtaining any of our components.
We regularly audit our suppliers for compliance with our quality system requirements, the QSR and/or applicable 
International Organization of Standardization (ISO) standards. We are an FDA-registered medical device manufacturer and 
certified to ISO 13485:2016. We routinely conduct internal audits of our quality systems in accordance with various 
international standards. 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, 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.
Human Capital Management 
Successful execution of our strategy is dependent on attracting, developing and retaining key employees and 
members of our management team. As of December 31, 2024, we had approximately 1,300 employees. Our Board of 
Directors, along with the Compensation Committee, provides oversight of human capital management including 
demographics, diversity and inclusion efforts, and aspects of employee compensation.

At AtriCure, our employees are crucial to the ongoing success of the company. 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, as well as to recruit new 
employees to support our growth. Recognizing the significance of our employees to our success, we include a “people 
objective” in our annual incentive plan to ensure focus and accountability. 
Talent Attraction and Retention
We attract top talent to AtriCure, provide mechanisms for them to take ownership of their career paths and support 
their career aspirations to build a long-term future with our company. Over the last five years, the voluntary turnover rate 
among our employees has remained consistently below 12%, outperforming the industry average for medical device 
companies. We conduct engagement surveys of our employees at least annually with our last Organizational Health Survey 
resulting in above average results when compared to similar size companies. In addition, our employees have voted us as a 
Top Workplace nine times in the past ten years, and internationally, our employees have voted us a Great Place to Work for 
three consecutive years. We also promote employee retention and development by supporting internal movement to create 
accretive experiences for our employees. We have made focused efforts to attract diverse candidates in our pipeline and 
have expanded our recruiting channels to connect with new communities. 
Talent Management and Development
Our philosophy of Talent Mastery is our aspirational commitment to spend as much time focusing on our talent as 
we do on our business strategies. Under this philosophy, we believe our leaders will better help attract, develop and retain 
talent. We are committed to identifying and developing the talents of our next-generation leaders, and conduct a 
comprehensive Talent and Organization Planning to position AtriCure with appropriate organization and leadership 
capability to meet current and future business needs. In that process, we review existing leaders and prospective leaders 
throughout the organization and determine the next best steps for their future development.
Employee development is an important part of the way we drive retention and foster a strong culture of learning. We 
have invested in programs to drive ongoing career development and provide a range of training courses and online 
resources for employees, and opportunities for coaching and mentoring. Programs and offerings for development include 
AMPLIFY, our leadership development program for mid-level leaders across the company; Manager Foundations 
Certification Program to provide all people-managers with tools and resources to be effective managers, and AtriCure 
YOUniversity, a series of competency-based courses for global employees. In addition to development programs for all 
employees, we have several functional development programs, such as the Engineering Development Program that offers 
four six-month rotations through different departments as part of our differentiated early pipeline talent development and 
the Sales Training Associates program focused on rotating talent within functions to support future commercial roles. 
Lastly, we provide tuition reimbursement for employees pursuing undergraduate and graduate degrees.
Diversity, Equity and Inclusion (DE&I)
We are driven by the belief that diverse skills and experiences produce better outcomes and more innovative 
solutions to improve patients' lives. We have an ongoing commitment to advancing DE&I throughout our workplace and 
the communities in which we operate. Our leaders create an environment that fosters a sense of belonging and ignites 
passion within their team. This leader-led approach to building an equitable and inclusive workforce has a longstanding 
commitment to fostering a workplace that rejects discrimination, celebrates differences, and promotes equality. In 2024, the 
Company earned recognition by Fast Company, Inc. as the company that offers the best opportunities for women 
innovators. This honor reflects our commitment to fostering an environment where women can thrive, innovate and lead in 
advancing solutions. Our DE&I framework guides our long-term vision and is grounded in the following objectives:
•
Attract and develop employees resembling the diversity of the communities and patients we serve.
•
Create a diverse talent pipeline by fostering awareness of STEM and healthcare careers for women and ethnically 
diverse groups.
•
Foster a culture of inclusion and belonging where all employees are valued and empowered.
•
Enhance DE&I understanding and behaviors through education and development.
•
Increase awareness and advocate for diversity in medical research and clinical trials through healthcare partnerships.
•
Collaborate with our partners to engage communities to promote heart health awareness.

Our DE&I efforts and programs advance our commitment by fostering employee understanding, intentionality and 
measurable processes. This commitment is also reflected in the current makeup of our Board of Directors, which helps to 
set the “tone at the top” for our DE&I initiatives.
Compensation and Benefits
Competitive compensation and benefits are an integral part of our efforts to attract and retain world-class talent. We 
are committed to regularly analyzing and evaluating the effectiveness of our compensation and benefit programs and 
benchmarking our programs against the market and our industry peers. Annual pay increases and other forms of incentive 
compensation are based on performance and market evaluation. Performance expectations are communicated to employees 
at the time of hiring, as well as upon internal transfer or promotion, and documented through our annual performance 
management process. 
Benefits for eligible U.S.-based employees include medical, dental and vision insurance; paid leave for vacation, 
illness and volunteer time; parental leave, fertility and adoption assistance; a 401(k) retirement plan that includes a 
company matching contribution; a stock purchase plan enabling employees to purchase AtriCure stock at a reduced price; 
and life and disability insurance. Our international employee benefits vary due to local regulations and offerings. We 
ensure compliance with all statutory and mandatory benefits which vary by country, such as medical, disability, retirement/
pension, workers compensation, accident, social benefits and paid leave. None of our employees are represented by a labor 
union, and we have never experienced any employment-related work stoppages. We consider our employee relations to be 
in good standing. Our attrition rate is historically lower than the industry average. AtriCure has a strong company culture, 
which is reflected in our employee engagement and overall success.
Safety for All Employees
We are committed to maintaining a safe workplace and promoting all our employees' well-being. 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. Since 2021, our Ohio office 
locations are entirely tobacco- and nicotine-free, and to the extent permitted in the local jurisdictions of our other offices, 
those locations are also tobacco- and nicotine-free.

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. We expect that sales of our ablation and LAAM 
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, 
managing the LAA and managing post-operative pain with Cryo Nerve Block therapy. The U.S. medical community’s 
acceptance of our products will depend upon our ability to demonstrate the safety and efficacy, advantages, short and 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 United States, 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.
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, other products or techniques to occlude the left atrial appendage or other products and techniques 
to manage post-operative pain. 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 our 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, technical and commercial 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. 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. 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 could affect the use of our products and 
harm our business and prospects.

17

Conversely, positive results from clinical trial experience should not be relied upon as evidence that any of our 
products will gain market acceptance 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 products 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 
(FDCA). Success in early clinical trials does not mean that future clinical trials will be successful because products 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 preclinical studies and clinical trials; 
•
change requirements for the approval or clearance of a product even after reviewing and providing comment on a 
protocol for a pivotal clinical trial;
•
approve or clear a product 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 products.
These factors would affect the rate and extent to which our products are adopted in the medical community.
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 may 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, local economic and political conditions, natural or other 
disasters and war or terrorist activities. In addition, the ability of our independent distributors to obtain financing 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
A prolonged downturn in macroeconomic conditions in which we operate may materially adversely affect our 
business.
A prolonged economic downturn as a result of the collateral effects of inflationary pressures, increases in interest 
rates, slower economic activity, a future outbreak of COVID-19 or a similar infectious disease, among other factors, may 
adversely impact our business. Specifically, impacts to procedure volumes and hospital staffing may result in reductions of 
our revenue and materially and adversely affect our results of operations and cash flows. Geopolitical issues around the 
world have impacted the global supply chain and could materially adversely affect global economic growth, disrupt 
discretionary spending habits and generally decrease demand for our products and services. Our customers’ ability to 
borrow money from their existing lenders or to obtain credit from other sources to purchase our products may be impaired, 
resulting in a decrease in sales. 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. We may also encounter interruption or delays in 
Table of Contents
18

the operations of FDA or other regulatory authorities, which may impact review and approval timelines. We are unable to 
predict the extent to which current or future worldwide economic conditions may impact our business. 
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 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 
United States and internationally could harm our business. Some healthcare providers in the United States have adopted or 
are considering a managed care system in which the 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, 
eliminating incremental procedure costs 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 market segments.
Adverse changes in governmental and third-party 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 Afib, prevention of stroke, or reduction of post-operative Afib, 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.
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 or our industry. This publicity could have a 
negative impact on our sales, our ability to attract and retain customers, 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, potential impact to our business from competitors or emerging technology 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 business, results of operations and financial condition and our clinical studies, or cause other adverse effects, 
including a decline in the price of our stock.
Table of Contents
19

We rely upon single and limited source third-party suppliers and third-party service 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 as well as third-party vendors for the manufacturing of our RF generator and our EPi-Sense System. We have 
significant concentrations with a limited number of vendors. It would be a time consuming and lengthy process to secure 
these products from an alternative supplier. Additionally, our devices are sterilized prior to use using ethylene oxide at 
third-party sterilizers. Recently, certain sterilization facilities have experienced voluntary or mandated temporary closures 
due to concerns over the impact of emissions of ethylene oxide from such facilities, and the Environmental Protection 
Agency has proposed regulations aimed at reducing hazardous air pollutants. We also rely on third parties to handle our 
warehousing and logistics functions for European and several other international 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 or sterilizers;
•
switching components may require product redesign and new submissions to FDA which would increase our costs and 
could significantly delay production or, if FDA refuses to approve the changes, completely eliminate our ability to sell 
our products;
•
future regulatory actions to modify sterilization processes may cause sterilizers to close, even on a temporary basis, or 
require new regulatory approvals for us to use, creating lost sterilization capacity and delays;
•
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 or sterilizers for any of the components used in our 
products or replacement of warehousing and logistics providers, if required, may not be accomplished quickly and could 
involve significant additional costs. Any interruption or delay in the supply of components, materials, sterilization 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 highly centralized, and disruption at our manufacturing facilities could increase 
our expenses and decrease our revenue.
Our manufacturing operations are highly centralized to our corporate headquarters. While we have taken precautions, 
such as qualifying a second building for manufacturing, we do not maintain a backup manufacturing facility outside of our 
Ohio campus, making us dependent on the current facilities 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 facilities 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.
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 supply and shortages of qualified personnel. These problems could result in delays in product 
Table of Contents
20

availability and increases in expenses. Any such delay or increased expense could adversely affect our ability to generate 
revenues and adversely impact our operating results.
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, hire, train and integrate 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 in Europe, 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 and training. Our business could be negatively impacted if any of these physicians end 
their relationship with us. 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. Like many other companies, we 
experience attempts to gain unauthorized access to our systems and information on a regular basis, and a number of our 
employees work remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities. Despite 
our security measures, including employee training, our information technology and infrastructure are vulnerable to cyber-
attacks, malicious intrusions, breakdowns, destruction, loss of data privacy, breaches due to employee error, malfeasance or 
other disruptions. Cyber-attacks are becoming more sophisticated and frequent, and our systems could be the target of 
malware, ransomware and other cyber-attacks. We have invested in our systems and the protection of our data to reduce the 
risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current or potential threats. We 
can give no assurances that these measures and efforts will prevent interruptions or breakdowns. If we are unable to detect 
or prevent a security breach or cyber-attack or other disruption from occurring, then we could incur losses or damage to our 
data, or inappropriate disclosure of our confidential information or that of others. We have cyber-insurance coverage that 
may not cover all possible events, and this insurance is subject to deductibles and coverage limitations. We could sustain 
damage to our reputation and customer and employee relationships, suffer disruptions to our business and incur increased 
operating costs including costs to mitigate any damage caused and protect against future damage, and be exposed to 
additional regulatory scrutiny or penalties and to civil litigation and possible financial liability, any of which could have a 
material adverse effect on 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. In addition, some of our software systems are 
cloud-based data management applications, hosted by third-party service providers whose security and information 
technology systems are subject to similar risks. The failure to protect either our or our service providers’ information 
technology infrastructure could disrupt our operations. 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 could 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.
Legal & Compliance Risks
We spend considerable time and money complying with federal, state and foreign regulations in addition to FDA 
regulations, and, if we do not fully comply with such regulations, we could face substantial penalties. 
We are subject to extensive regulations 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 among other things, requires 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, such as the General Data Protection Regulation in the European Union, that govern collection, 
use, disclosure, transfer and storage of personal data that we may collect from our employees, consultants or in 
conjunction with clinical trials;
•
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 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.
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 FDA or other state or federal agencies, including the U.S. Department of Justice (USDOJ), which may include 
any of the following sanctions, among others:
•
warning letters, fines, injunctions, consent decrees and civil penalties;
•
repair, replacement, refunds, recall or seizure of our products;
•
operating restrictions, partial suspension or total shutdown of production;
•
suspension or termination of our clinical trials;
•
refusing or delaying our pending requests for 510(k) clearance or PMAs, new intended uses or modifications to 
existing products;
•
withdrawing 510(k) clearance or PMAs that have already been granted; and
•
criminal prosecution.
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.

23

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 them for the 
treatment of Afib, prevention of stroke, or reduction of post-operative Afib, 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 and/or 
reduction of Afib and related complications, such as stroke. Unless the products are approved or cleared by FDA 
specifically for the treatment of Afib, prevention of stroke, or reduction of post-operative Afib, 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, 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 and EPi-Sense System have 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, prevention of stroke, or reduction of post-operative Afib. Unless and until we obtain FDA clearance or 
approval for the use of our other products to treat Afib, prevent stroke, or reduce post-operative Afib, we, and others acting 
on our behalf, may not claim in the United States that such products are safe and effective for such uses or otherwise 
promote them for such uses. Similar restrictions also exist outside of the United States. 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 or PMA-approved 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 or PMA supplement. 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 component parts, 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 facilities 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 inspection 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. 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.
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, nerves, 
internal bleeding, death, paralysis 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, any current or future 
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 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 
Table of Contents
26

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:
•
export restrictions and controls relating to technology;
•
pricing pressure that we may experience internationally;
•
difficulties in enforcing agreements and collecting receivables through certain foreign legal systems;
•
political and economic instability;
•
consequences arising from natural disasters and other similar catastrophes, such as hurricanes, tornados, earthquakes, 
floods and tsunamis;
•
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.
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.

The use of artificial intelligence ("AI") technology by our employees or business partners could result in misuse or 
loss of proprietary information, violation of laws and regulations, or damage to our reputation and credibility.
Our employees and business partners may use AI technology to perform their work. Our sensitive information 
could be leaked, disclosed, or revealed as a result of or in connection with use of AI technology. Additionally, the use and 
disclosure of personal data in AI technology is subject to various data privacy laws and other data privacy obligations. 
Governments have passed and are likely to pass additional laws regulating AI. Our use of this technology could result in 
additional compliance costs, regulatory investigations and actions and lawsuits. Further, the cost to comply with such laws 
or regulations, or decisions and/or guidance interpreting existing laws, could be significant and would increase our 
operating expenses, which could adversely affect our business, financial condition and results of operations.
Financial Risks
Our quarterly financial results are likely to fluctuate significantly because the pace of adoption of our products by 
clinicians is uncertain.
Due to differing rates of adoption of our devices, our quarterly operating results may fluctuate significantly. Current 
worldwide economic conditions, natural disasters and other factors discussed in this “Risk Factors” section also may 
impact our sales results, causing our quarterly operating results to be 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 a history of net losses, including $44,698 in 2024, $30,438 in 2023, and $46,466 in 2022. As of 
December 31, 2024, we had an accumulated deficit of $401,755.
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 may 
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.
Governmental authorities may challenge 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 transfer pricing laws, including those relating to the flow of funds between the parent and subsidiaries. If tax 
authorities challenge our intercompany transfer pricing, 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 including minimum taxation. 
As these guidelines are formally adopted by the OECD, it is possible that separate taxing jurisdictions in which we operate 
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, including 
changes in minimum taxation, 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 becomes 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, 2024, we had $234,781 in goodwill, which represents 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). 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.
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 into 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. Although 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.
We may be unable to comply with the covenants of our Credit Agreement.
The Credit Agreement entered into on January 5, 2024, contains specific financial covenants and a minimum 
liquidity requirement, along with other terms restricting indebtedness, liens, investments and acquisitions, asset 
dispositions, certain payments and other customary representations and warranties. The Credit Agreement contains 
mandatory prepayment provisions which require prepayment of amounts outstanding (i) upon the receipt of proceeds from 
the issuance of any non-permitted indebtedness and (ii) when there is an Availability shortfall, as defined. The occurrence 
of an event of default could result in an obligation to repay all obligations in full and a right by our lenders to exercise all 
remedies available to them. If we are unable to pay those amounts, our lenders could proceed against the collateral granted 
to it pursuant to the Credit Agreement, and we may in turn lose access to both our collateral and 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 rate of adoption 
of our products, projected hiring to support our growth, continued increase of our market share, potential impact from 
competitive devices and therapies, and 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 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, our business or our markets. 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 a smaller market capitalization, 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 has had and may continue to have 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 experienced 
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 
prearranged 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.
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 the following:
•
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.
ITEM 1B. UNRESOLVED STAFF COMMENTS 
None.
ITEM 1C. CYBERSECURITY 
Risk Management and Strategy
We are committed to preserving the trust and confidence of our stakeholders by taking appropriate technical and 
organizational measures for maintaining information security and data privacy. Our cybersecurity program allows us to 
assess, identify and manage information security and cybersecurity threats through robust risk assessment and prevention 
measures to facilitate communication, training, awareness and incident response procedures. We have established policies 
and procedures to ensure timely and appropriate notifications to relevant parties and regulators as required for 
cybersecurity threats and data breaches. 
We have continued to expand investments in information security, including additional end-user training, using 
layered defenses, identifying and protecting critical assets, strengthening monitoring and alerting mechanisms, and 
engaging experts. Information security awareness trainings are a compliance requirement for employees. We regularly test 
defenses by performing simulations and drills at both a technical level (including through penetration tests) and by 
reviewing our operational policies and procedures with third-party experts.
Our data breach response plan designates an incident response team comprised of senior leaders within information 
technology, finance, legal and compliance functions to ensure timely diagnosis and mitigation of cyber events. The incident 
response team is responsible for determining whether a cybersecurity incident is material and requires current reporting 
pursuant to SEC Form 8-K Item 1.05 (Material Cybersecurity Incidents). In conducting the assessment, the team considers 
Table of Contents
31

factors including, but not limited to: the probability of an adverse outcome; the potential significance of loss; the nature and 
extent of harm to individuals, customers, and vendors; the nature and extent of harm to our competitive position or 
reputation; and the possibility of litigation or regulatory investigations. 
To ensure our cybersecurity programs adhere to industry best practices, we have adopted the National Institute of 
Standards and Technology (NIST) Cybersecurity Framework and subscribed to the principles of Zero Trust. Both models 
represent recognized best practices for security and the capabilities needed to identify, protect, detect and respond to 
cybersecurity risks and challenges. We evaluate our physical, electronic and administrative safeguards on a continuous 
basis to ensure they are effectively deployed across the business. 
We also work with trusted and recognized third parties to help us assess, strengthen and monitor the operations of 
our information security program. We engage third-party services to conduct evaluations of our security controls, whether 
through penetration testing, independent audits or consulting on best practices to address new challenges. These 
evaluations include testing both the design and operational effectiveness of security controls. We also share and receive 
threat intelligence with information sharing and analysis centers and cybersecurity associations.
Assessing, identifying and managing cybersecurity related risks are integrated into our overall enterprise risk 
management (ERM) process, which evaluates and assesses top risks to the enterprise on a periodic basis. To the extent the 
ERM process identifies a heightened cybersecurity related risk, risk owners are assigned to develop risk mitigation plans, 
which are then tracked to completion. The ERM process's risk assessment is presented to the Board of Directors. In 
addition to assessing our own cybersecurity preparedness, we also consider cybersecurity risks associated with the use of 
third-party software and service providers. Such providers are subject to security risk assessments at time of onboarding, 
contract renewal and upon detection of an increase in risk profile. On an annual basis we review System and Organization 
Controls (SOC) 1 or SOC 2 reports for third-party service providers deemed significant to our environment. 
Despite the Company’s security measures and programs, our information technology and infrastructure are 
vulnerable to cybersecurity incidents, intrusions and attacks, any of which could have a materially adverse effect on our 
business, financial results, revenues and competitive position. See “Part I—Item 1A. Risk Factors” for further discussion of 
these risks. 
Governance
Our Board of Directors is responsible for the oversight of cybersecurity risks and threats. The Board has delegated 
certain information security and data privacy oversight to the Audit Committee and the Compliance, Quality and Risk 
Committee (CQRC) of the Board. The CQRC oversees compliance with information security and data privacy laws, while 
the Audit Committee has oversight responsibility for cybersecurity risks related to accounting, audit and financial matters. 
The CQRC, Audit Committee and management report to the Board on a periodic basis regarding our information security 
and data privacy functions, including any cybersecurity threats. 
The CQRC is responsible for oversight of our cybersecurity policy, procedures and risk mitigation. Our information 
technology (IT) leadership briefs the CQRC on a periodic basis on information security matters, including the current 
cybersecurity landscape, progress on information security initiatives and accomplishments, and reports on material 
cybersecurity incidents, as needed. Our enterprise risk management team reports address the Company’s cybersecurity risk 
management processes. Our Chief Legal Officer oversees the management of our ERM program and has over a decade of 
experience in risk management. The Chair of the CQRC is an expert in enterprise risk assessment and mitigation and holds 
a CERT Certificate in Cybersecurity Oversight.
The Audit Committee is responsible for reviewing our disclosures on cybersecurity risk management, strategy and 
governance in our Annual Report on Form 10-K. The Audit Committee assists in determining materiality for timely 
reporting of cybersecurity incidents and is notified immediately if the incident response team has assessed that a material 
event may have occurred that may require filing an SEC Current Report on Form 8-K. 
The Vice President of Information Technology, assisted by our broader IT team, is responsible for setting the 
strategic direction and priorities for information security, coordination of enterprise-wide compliance with information 
security policies and procedures, as well as day-to-day information security management. Our Vice President of IT has 
served in various roles in information technology and information security for over 20 years. Our information security team 
has an aggregate of more than 60 years of experience in information technology roles across several industries.

Year Ended December 31, 2023 compared to December 31, 2022
For a comparison of our results of operations for the years ended December 31, 2023 and December 31, 2022, 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 year ended December 31, 2023, filed with the SEC on February 16, 2024.
Overview
We are a leading innovator in treatments for atrial fibrillation, left atrial appendage management and post-operative 
pain management. Our ablation and left atrial appendage management 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 (or “concomitant” to) such a procedure. Minimally invasive 
procedures are performed on a standalone basis, and often include multi-disciplinary or “hybrid” approaches, combining 
surgical procedures using AtriCure ablation and LAAM products with catheter ablation procedures performed by 
electrophysiologists. Our pain management devices are used by physicians to freeze nerves during cardiothoracic or 
thoracic surgical procedures. 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, Germany, France, the 
United Kingdom, the Benelux region, Australia and Canada. We also sell our products to distributors who in turn sell our 
products to medical centers in other markets. Our business is primarily transacted in U.S. Dollars; direct international sales 
transactions are transacted in Euros, British Pounds, Australian Dollars or Canadian Dollars. 
In 2024, we realized significant global revenue growth and continued our strategic initiatives of product innovation, 
clinical science and physician education and training to expand awareness and adoption. Our worldwide revenues for the 
year ended December 31, 2024 of $465,307 was an increase of 16.5% over the prior year driven by growing adoption 
across key product lines as well as new product launches. Historically there have been limited competitors in our key 
markets, but new entrants are marketing and developing competing products, procedures, and/or clinical solutions that may 
cause variability in our results.
Highlights of the strategic and operational advancements in 2024 include:
PRODUCT INNOVATION. We continue to invest in research and development of new products and pursue 
regulatory approvals to market and sell globally across all franchises.
•
Open. Upon receiving regulatory approval during the third quarter of 2024, we began selling the EnCompass 
clamp in CE-marked countries in the European Union, representing a significant expansion of our open ablation 
franchise products in Europe. 
•
Minimally invasive. In the first half of 2024, FDA granted 510(k) clearance for EPi-Ease, our Hybrid access 
device to facilitate guide-wire delivery, vacuum application and endoscope insertion. During the third quarter, 
FDA granted 510(k) clearance for our EnCapture clamp, the newest in our line of Isolator Synergy Ablation 
System clamps, with enhanced geometry and features to facilitate engagement with intended cardiac tissue.
•
Pain management. During the second quarter of 2024, we launched the cryoSPHERE+ cryoablation probe for 
pain management in the United States. The cryoSPHERE+ device leverages new technology that minimizes 
thermal loss by focusing energy at the ball tip, allowing for a reduction in freeze time by 25%. Further, the 
cryoSPHERE MAX probe was launched during the fourth quarter of 2024 and features a larger ball tip designed 
Table of Contents
35

to optimize Cryo Nerve Block therapy. This new probe reduces freeze times by 50% when compared to the first 
generation cryoSPHERE cryoablation probe, and over 30% when compared to the cryoSPHERE+ probe. 
•
Appendage management. We launched the AtriClip FLEX-Mini device in the United States during the third 
quarter of 2024. The AtriClip FLEX-Mini sets a new standard as the smallest profile for surgical LAA device on 
the market and builds upon the proven technology of our AtriClip platform, with ease of use and design simplicity 
that offers enhanced access and increased visibility for physicians. We also obtained additional international 
regulatory approvals for our AtriClip platform during the third quarter. In China, we received approval to market 
and sell several models of our AtriClip Left Atrial Appendage Exclusion System from the National Medical 
Products Administration (NMPA) of China. In CE-marked countries in Europe, we received expanded indication 
for the AtriClip for use in patients at high risk of thromboembolism for whom left atrial appendage exclusion is 
warranted.
Throughout 2024, we received several additional CE Mark certifications under the European Union Medical Device 
Regulation (EU MDR). As of December 31, 2024, substantially all of our products were cleared under EU MDR. During 
the fourth quarter of 2024, we entered into an exclusive licensing agreement with a third-party to co-develop and 
commercialize equipment incorporating pulsed field ablation. See Note 3 - Asset Acquisition for additional information.
CLINICAL SCIENCE. We invest in studies to expand labeling claims, support various indications for our products 
and publish clinical data for therapies and procedures involving our products. During 2024, we supported the publication of 
19 articles and 17 congress abstracts featuring clinical studies with our product.
LeAAPS. The Left Atrial Appendage Exclusion for Prophylactic Stroke Reduction (LeAAPS) IDE clinical trial is 
designed to evaluate the effectiveness of prophylactic LAA exclusion using the AtriClip LAA Exclusion System for the 
prevention of ischemic stroke or systemic arterial embolism in cardiac surgery patients without pre-operative AF diagnosis 
who are at risk for these events. This prospective, multicenter, randomized trial evaluates safety at 30 days post-procedure 
to demonstrate no increased risk with LAA exclusion during cardiac surgery, and efficacy over a minimum follow-up of 
five years post procedure. The trial provides for enrollment of up to 6,500 subjects at up to 250 sites worldwide. In January 
2023, the first patient was enrolled in the trial, and we ended 2024 with over 4,200 patients enrolled. Site initiation and 
enrollment is ongoing.
BoxX-NoAF. The EnCompass clamp and the AtriClip in Box Lesion and Left Atrial Appendage EXclusion Procedure 
for the Prevention of New Onset of Atrial Fibrillation (BoxX-NoAF) IDE trial will evaluate the impact of concomitant 
ablation and LAA exclusion in non-AF patients for the reduction of post-operative AF (POAF) and Clinical AF. This 
prospective, multi-center, multi-national randomized trial evaluates safety at 30 days post-procedure for POAF and 
secondary effectiveness for Clinical AF through three years. The trial provides for enrollment of up to 960 subjects. During 
the fourth quarter of 2024, FDA approved the trial protocol. We expect site initiation to begin by the end of 2025.
TRAINING. Our professional education and marketing teams conduct a variety of virtual and in-person training 
programs for physicians and other healthcare professionals. These training methods ensure access to continuing education 
and awareness of our products and related procedures. During 2023, we launched new training courses for Advanced 
Practice Providers, pain management in pectus procedures, as well as a best practice course for developing arrhythmia 
programs, with a primary focus on Hybrid therapies. These trainings allow for collaborative, hands-on engagement with 
our physician partners and other healthcare professionals. Additionally, our professional education courses continue to be 
enhanced by the use of simulation models or synthetic cadavers, known as CADets. These reusable CADets provide a 
sustainable alternative to the use of cadaver specimens, in addition to increasing the efficiencies of education and more cost 
effective training alternatives. In 2024, we continue to innovate physician training to improve accessibility and efficiency 
for our physician partners. We are currently piloting the use of live streaming to enable remote proctoring and case 
observation.
SOCIETY GUIDELINES. In 2024, the European Society of Cardiology (ESC) released Guidelines for Management 
of Atrial Fibrillation developed in collaboration with European Association of Cardio-Thoracic Surgery (EACTS), in 
which they upgraded LAAM to the highest Class 1 recommendation. During 2023, the American College of Cardiology 
(ACC), American Heart Association (AHA), American College of Clinical Pharmacy (ACCP) and HRS released 
Guidelines for Diagnosis and Management of Atrial Fibrillation, and upgraded LAAM to the highest recommendation of 
Class 1 and included Hybrid AF Therapy as a Class 2 recommendation. All major cardiac societal guidelines now include a 
Class 1 recommendation for surgical management of the left atrial appendage. These societal guidelines are reflective of 
the scientific evidence suggesting that surgical and hybrid ablation is safe and effective for patients who have Afib.

Worldwide revenue increased 16.5% as reported and on a constant currency basis. We experienced growth in all key 
product lines as a result of deepening market penetration, continuing physician adoption and new product launches. 
International revenue increased 25.6% as reported and on a constant currency basis, across all franchises and major 
geographic regions, while key products contributing to the increase in revenue in the United States were:
•
EnCompass clamp in open ablation,
•
cryoSPHERE probes for post-operative pain management and 
•
AtriClip® Flex·V® for appendage management. 
Revenue reported on a constant currency basis is a non-GAAP measure calculated by applying previous period 
foreign currency exchange rates, which are determined by the average daily 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 increased $18,908 primarily reflecting higher sales volumes. 
Gross margin decreased by 55 basis points driven by less favorable geographic and product mix, as well as an increase in 
product costs.
Research and development expenses. Research and development expenses increased $22,263, or 30.1%. During 
2024, we entered into an exclusive licensing agreement requiring upfront cash payment of $12,000 for the acquired in-
process research and development (IPR&D), which was included in research and development expenses in 2024. See Note 
3 – Asset Acquisition for further information. Expansion of product development, regulatory and clinical teams resulted in 
additional headcount-related costs (including travel and share-based compensation) of $6,773. Clinical trial expenses 
increased $4,801 due to increased trial activity driven by our LeAAPS clinical trial. These increases were partially offset by 
a $1,606 decrease in product development project spend and regulatory approval costs as several new products were 
brought to market in 2024, including cryoSPHERE+ and AtriClip FLEX-Mini.
Selling, general and administrative expenses. Selling, general and administrative expenses increased $38,221, or 
15.1%. Personnel costs, including travel and share-based compensation, increased $27,384 as a result of growth in 
headcount and variable compensation. Operational growth drove $2,156 additional professional services, IT and corporate 
costs along with $2,079 additional marketing and meeting activities. Finally, the increase reflects a $4,412 non-recurring 
net gain in 2023 related to legal settlements. See Note 11 – Commitments and Contingencies for related discussion.
Other income and expense. During 2024, the Company recognized a loss on debt extinguishment of $1,362. See 
Note 9 - Indebtedness for related discussion. The remaining activity consists primarily of net interest expense and net 
foreign currency transaction losses.
Liquidity and Capital Resources 
As of December 31, 2024, we had cash and cash equivalents of $122,721 and unused borrowing capacity of 
approximately $61,885 under our existing credit agreement. All cash equivalents and most of our operating cash are held in 
United States financial institutions. A minor portion of our cash is held in foreign banks to support our international 
operations. We had net working capital of $194,402 and an accumulated deficit of $401,755 as of December 31, 2024. 
Uses of liquidity and capital resources. Our executive officers and Board of Directors review our funding sources 
and future capital requirements in connection with our annual operating plan and periodic updates to the plan. Our principal 
cash requirements include costs of operations, capital expenditures, debt service costs and other contractual obligations. 
Our future capital requirements depend on a number of factors, including, without limitation: market acceptance of our 
current and future products; investments in working capital; costs to develop and support our products, including 
professional training, clinical trials and contractual development costs; costs to expand and support our sales and marketing 
efforts; operating and filing costs required by regulatory policies or laws; costs for clinical trials and to secure regulatory 
approval for new products; costs to prosecute, defend and enforce our intellectual property rights; costs to defend against 
and/or resolve litigation or claims against us; maintenance and enhancements to our information systems and security; and 
possible acquisitions and joint ventures, including potential business integration costs. We continue to evaluate additional 
measures to maintain financial flexibility, and we will continue to closely monitor macroeconomic conditions including, 
but not limited to, inflationary pressures, changing interest rates, and fluctuations in currency exchange rates that may 
impact our liquidity and access to capital resources. 
Credit facility. On January 5, 2024, we entered into an asset-based credit agreement with JPMorgan Chase Bank, 
N.A. as Administrative Agent, JPMorgan Chase Bank, N.A. and Silicon Valley Bank, a division of First-Citizen Bank and 
Trust Company, as Joint Lead Arrangers and Joint Bookrunners (Credit Agreement) that provides for a $125,000 asset-
based revolving credit facility (ABL Facility), with an option to increase the revolving commitment by an additional 
$40,000. A portion of the ABL facility, limited to $5,000, is available for the issuance of letters of credit. The Credit 
Agreement has a three-year term and expires January 5, 2027. Amounts available to be drawn from time to time under the 
ABL Facility are determined by calculating the applicable borrowing base, which is based upon applicable percentages of 
the values of eligible accounts receivable, eligible inventory, eligible liquid assets, less reserves as determined by the 
Administrative Agent, all as specified in the Credit Agreement. The borrowings bear interest at a rate per annum equal to, 
at the Company's election: (i) an alternate base rate (ABR) plus an applicable margin or (ii) an adjusted term secured 
overnight financing rate (SOFR) plus an applicable margin. The proceeds of the ABL Facility were used to terminate the 
Company’s indebtedness under the prior loan agreement with Silicon Valley Bank. As of December 31, 2024, our 
outstanding debt was $61,865 and we had unused borrowing availability of approximately $61,885.
Our corporate headquarters lease requires a $1,250 letter of credit which renews annually and remains outstanding as 
of December 31, 2024.

For additional information on the terms and conditions, as well as applicable interest and fee payments, see Note 9 – 
Indebtedness.
Capital Expenditures. We incur capital expenditures on an ongoing basis to continue investment in our growth and 
our ability to better serve our customers. In recent years, we have expanded the manufacturing and engineering facilities in 
our Mason, Ohio campus and expect to continue to invest in facilities to support our growth.
Other Contractual Obligations. Our future obligations include both current and long-term obligations. In 2022, the 
Company entered into a clinical trial management agreement for the LeAAPS clinical trial. The terms of the agreement 
require payments upon achievement of various enrollment and project milestones over the estimated ten-year term, yet the 
agreement may be terminated early for any reason. Furthermore, we incur additional variable costs, including pass through 
costs from clinical trial sites. We expect to disburse between $14,000 and $17,000 of fixed and variable costs based on 
estimated achievement of milestone payments, site initiation and trial enrollment within the next twelve months.
In 2024, we entered into an exclusive licensing agreement to co-develop and commercialize equipment incorporating 
PFA technology. The agreement requires that we pay additional contingent consideration in cash upon achievement of 
specified developmental and regulatory approval milestones within defined periods over the ten-year term. We expect to 
disburse between $6,000 and $10,000 based on estimated achievement of milestone payments within the next twelve 
months. For additional information, see Note 3 – Asset Acquisition.
We have operating and finance leases primarily for our offices, manufacturing and warehouse facilities and 
automobiles. Our finance leases consist primarily of principal and interest payments related to our Mason, Ohio 
headquarters building. As of December 31, 2024, current finance lease obligations are $1,186 and long-term obligations are 
$7,281. Our operating leases for office and warehouse space includes current obligations of $1,619 and long-term 
obligations of $4,579 as of December 31, 2024. For additional information, see Note 10 – Leases. 
We have a contractual obligation for a contingent consideration payment under the SentreHEART merger agreement 
that would be paid in AtriCure common stock and cash, up to a specified maximum number of shares. As of December 31, 
2024, we believe the likelihood of payment is remote, and the estimated fair value of the contingent consideration is $0. 
See Note 2 – Fair Value. 
Sources of liquidity. We believe that our current cash and cash equivalents, along with the cash we expect to 
generate or use for operations or access via our Credit Agreement, will be sufficient to meet our anticipated cash needs for 
working capital and capital expenditures for at least the next twelve months. However, we have a shelf registration 
statement on file with the SEC which allows us to sell any combination of 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 the shelf registration statement for the foreseeable future. 
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 would have rights senior to those associated with our common stock and could contain covenants that would 
restrict our operations. Finally, our Credit Agreement requires 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.

Cash flows provided by operating activities. Net cash provided by operating activities increased $7,720 in 2024 as 
compared to 2023. While operating results declined $14,260, this decline was driven primarily by an increase in 
adjustments to income and changes in non-cash expenses as well as the acquisition of in-process research and development 
for $12,000. Changes in non-cash expenses include $4,677 increase in share-based compensation, $3,920 increase in 
depreciation & amortization and $1,362 loss on extinguishment of debt. Cash used in working capital remained flat year 
over year due to moderating investments in inventory in 2024, offset by higher annual variable compensation due to 
improved operating performance.
Cash flows provided by investing activities. Net cash provided by investing activities increased by $8,417 in 2024 
compared to 2023. This increase is attributable to a $18,000 decrease in cash paid for acquisitions year over year, offset by 
a $10,147 decrease in maturities of available-for-sale securities.
Cash flows used in financing activities. Net cash used in financing activities increased by $3,571 in 2024 compared 
to 2023, driven by $1,686 payment for extinguishment of debt and financing fees, net of borrowings, and a $1,491 decrease 
in proceeds from stock option exercises and the employee stock purchase plan. 
Inflation 
Inflationary pressures may have an adverse impact on our results of operations or financial condition in the 
foreseeable future. Inflation has impacted our operating costs throughout 2024 and 2023. Continued increases in our cost of 
revenue may affect our ability to maintain our gross margin if selling prices of our products do not increase 
commensurately, while continued increases in our operating expenses may adversely affect our operating results and the 
ability to make discretionary investments. We will continue to monitor the impact of inflation on our cost of revenue and 
operating expenses.
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. 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.
Table of Contents
40

We believe the following critical accounting policies involve a significant level of estimation uncertainty and 
judgments that are reasonably likely to have a material impact on our Consolidated Financial Statements. We base our 
judgments and estimates on historical experience, current conditions and other reasonable factors. Actual results could 
differ from those estimates under different assumptions or conditions.
Revenue Recognition—Revenue is generated 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. 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 are not obligated to accept product returns 
unless a product is defective as manufactured, and we do not provide customers with the right to a refund.
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 sales 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.
Share-Based Employee Compensation—We estimate the fair value of performance share awards with a 
performance condition initially based on the closing stock price on the date of grant assuming the performance goal will be 
achieved. Such performance share awards have specified performance targets based on the compound annual growth rate 
(CAGR) of our revenue over a three-year performance period. With respect to these performance share awards, the number 
of shares that vest and are issued to the recipient is based upon revenue performance over the performance period. We may 
adjust the expense over the performance period based on changes to estimates of performance target achievement. If such 
goals are not met or service is not rendered for the requisite service period, no compensation cost is recognized, and any 
recognized compensation cost from prior periods will be reversed.
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 along with 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 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 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 a 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 taxable income, future reversals of 
existing taxable temporary differences, taxable income in prior carryforward years 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 for a valuation allowance. Our valuation allowance offsets 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.

Statements in Item 8 of Part II for more information regarding recent accounting pronouncements.
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. 
Table of Contents
41

Credit and Interest Rate Risk
The Company invests its cash primarily in money market accounts, U.S. government and agency obligations, 
corporate bonds, and asset-backed securities. Although the Company believes it has invested in a conservative manner, 
with preservation being the primary investment objective, the value of the securities held will fluctuate with changes in 
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 to maintain liquidity and preserve principal without 
significantly increasing risk.
Financial instruments that potentially subject the Company to credit risk consist of cash equivalents and investments 
in corporate bonds. The Company maintains deposit accounts in federally insured financial institutions in excess of 
federally insured limits. Cash held in financial institutions in foreign countries is not significant. Although these depository 
accounts may exceed government insured depository limits, we have evaluated the credit worthiness of these applicable 
financial institutions and determined the risk of material financial loss due to the exposure of such credit risk to be remote. 
The Company also maintains investments in money market funds that are not federally insured. 
We are subject to interest rate risk as rate fluctuations impact cash payments for outstanding borrowings. 
Outstanding amounts under the Credit Agreement bear interest at a rate per annum equal to, at the Company's election: (i) 
an alternate base rate (ABR) plus an applicable margin or (ii) an adjusted term secured overnight financing rate (SOFR) 
plus an applicable margin. Alternate base rate is equal to the greatest of Prime, the NYFRB Rate plus 0.50% and Adjusted 
Term SOFR Rate plus 1.00%. The applicable margin spread is 1.50% to 2.75%, as determined by the average excess 
availability of the aggregate revolving commitment. All swingline loans bear interest at a rate per annum equal to the ABR 
plus the applicable margin under the Credit Agreement. Interest periods for SOFR Term Benchmark borrowings range 
from one month, three months or six months, at the Company's election. Interest rate risk is highly sensitive due to many 
factors, including United States monetary and tax policies and United states and international economic factors beyond our 
control. A hypothetical 100 basis-point (one percentage point) increase or decrease in interest rates compared to actual rates 
at December 31, 2024, would not have had a significant effect on our results. 
Foreign Currency Exchange Rate Risk
We sell our products to medical centers through our direct sales force in the United States, Germany, France, the 
United Kingdom, Australia and Canada. We also sell our products to distributors who in turn sell our products to medical 
centers in Japan, China and other international markets. Our business is primarily transacted in U.S. Dollars; direct 
international sales transactions are transacted in Euros, British Pounds, Australian Dollars or Canadian Dollars. Sales to 
international distributors outside of Europe are under agreements primarily denominated 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. 
Products sold by AtriCure Europe, B.V. and its subsidiaries are primarily denominated in Euros or British Pounds. 
European product sales accounted for 10.4% and 9.4% of the Company’s total revenue for 2024 and 2023. Accordingly, 
the Company is exposed to exchange rate fluctuations between the Euro and the U.S. Dollar and between the British Pound 
and the Euro. To a lesser extent, the Company is also exposed to exchange rate fluctuations between the Australian and 
Canadian Dollars to the U.S. Dollar. For 2024 and 2023, foreign currency transaction losses of $272 and $101 were 
recorded primarily in connection with settlements of the intercompany balances and invoices transacted in Euros, British 
Pounds, Australian Dollars or Canadian Dollars. 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, 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 2022, we entered into a clinical trial management agreement for the LeAAPS clinical trial. The terms of the 
agreement require fixed payments upon achievement of various enrollment and project milestones over the estimated ten-
year term. Additional variable costs, including pass through costs incurred at clinical trial sites, will be billed to us by the 
contracted party. Fixed milestone payments are denominated in Canadian Dollars, while variable pass-through fees 
incurred at clinical trial sites outside the United States may be billed in U.S. Dollars or other local currencies. Fluctuations 
in the conversation rates of the U.S. Dollar to the Canadian Dollar and local currencies of international trial sites may 
impact the cash outlay required for future milestone payments and variable pass-through costs under the clinical trial 
management agreement.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 
To the stockholders and the Board of Directors of 
AtriCure, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of AtriCure, Inc. and subsidiaries (the "Company") as of 
December 31, 2024 and 2023, the related consolidated statements of operations and comprehensive (loss) income, 
stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2024, and the related 
notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all 
material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its 
operations and its cash flows for each of the three years in the period ended December 31, 2024, 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, 2024, 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 14, 2025, 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 Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements 
that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or 
disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex 
judgments. The communication of 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 matter below, providing a separate opinion on the 
critical audit matter or on the accounts or disclosures to which it relates.

Valuation of Performance Shares - Refer to Note 15 to the financial statements
Critical Audit Matter Description
Performance share awards and performance share units (collectively, Performance Shares) were granted in 2024 with a 
grant date fair value of $15,007. The Performance Shares vest based on the achievement of performance conditions and/or 
market conditions.
The number of Performance Shares with a market condition that vest and are issued to the recipient is based upon either: (i) 
the Company’s total shareholder return (TSR) relative to the TSR of the selected market index or (ii) the Company’s 
simple moving average of the closing price of the Company’s Common Stock during the sixty calendar days immediately 
prior to and including the Measurement Period Dates at the end of the defined performance period. A Monte Carlo 
simulation was performed to estimate the fair value of the awards with a market condition on the date of grant. The number 
of Performance Shares with a performance condition that vest and are issued to the recipient is measured based on the 
Company’s revenue compound annual growth rate at the end of the defined performance period as compared to a target 
threshold. The Company’s share-based compensation expense is recognized over the requisite service period as the 
employee renders service. 
The determination of fair value on the grant date is affected by the stock price of the Company and the market index, as 
defined by the award agreement, at the beginning of the service period and grant date, the expected stock price volatility of 
the Company and the market index over the performance period, the risk-free interest rate, and/or the correlation 
coefficient of the daily returns for the Company and the market index over the performance period. 
Given the level of judgment involved by management to determine the grant date fair value of the Performance Awards, 
including the use of a specialist for awards with a market condition, audit procedures 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 determination of the grant date fair value of the Performance Shares 
included the following, among others:
•
We inquired with management regarding the key valuation assumptions and the methodology used in the 
determination of the grant date fair value of the Performance Shares.
•
We tested the design and operating effectiveness of the Company's internal controls over the determination of the grant 
date fair value of the Performance Shares.
•
We tested the accuracy of the data used in measuring the awards by agreeing the underlying inputs, such as grant date, 
share price, and vesting conditions, among others, back to source documents, such as compensation committee minutes 
or Performance Share agreements.
•
We evaluated management’s valuation of Performance Shares with a performance condition through testing of revenue 
growth assumptions over the defined performance period by comparing to the Company’s annual plan and external 
guidance. 
•
With the assistance of our fair value specialists, we evaluated management's valuation of Performance Shares with a 
market condition by:
▪
Evaluating the Monte Carlo simulation methodology and the reasonableness of the valuation assumptions, 
including the risk-free interest rate, expected volatility, and the correlation coefficients.
▪
Independently calculating a fair value estimate for the market condition Performance Shares using the underlying 
agreement and independently calculated valuation inputs.

1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of the Business— AtriCure, Inc. (the “Company” or “AtriCure”) is a leading innovator in surgical treatments 
and therapies for atrial fibrillation, left atrial appendage management and post-operative pain 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 its 
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 and money market funds with 
financial institutions.
Investments—The Company invests primarily in government and agency obligations, corporate bonds, commercial 
paper and asset-backed securities and classifies all investments as available-for-sale. Investments maturing in less than one 
year are classified as short-term investments. 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—Revenue is generated primarily from the sale of medical devices. Sales of devices are 
categorized based on the type of product as follows: open ablation, minimally invasive ablation, pain management and 
appendage management. The Company recognizes revenue when control of promised devices is transferred to customers in 
an amount that reflects the consideration the Company expects to be entitled to in exchange for those devices. Revenue is 
recognized at a point in time upon shipment or delivery of products. Shipping and handling activities performed after 
control transfers to customers are considered activities to fulfill the promise to transfer the products. Revenue includes 
shipping and handling revenue of $2,421, $1,860 and $1,496 in the years ended December 31, 2024, 2023 and 2022.
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 some exceptions. The Company does not maintain any post-
shipping obligations to customers; no installation, calibration or testing of products is performed subsequent to shipment in 
order to render products operational. The Company expects to be entitled to the total consideration for the products ordered 
as product pricing is fixed, and there are no adjustments for a significant financing component as payment terms fall within 
one year. 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 commission expense for product sales and royalties paid for sales of 
certain products. As revenue from product sales are satisfied at a point in time, commission expense and royalties are 
incurred at that point in time rather than over time. Commissions are included in selling, general and administrative 
expenses, while royalties are included in cost of revenue.
Significant judgments and estimates involved in the Company’s recognition of revenue include the estimation of a 
provision for returns. In the normal course of business, the Company is not obligated to accept product returns unless a 
product is defective as manufactured. The Company does not provide customers with the right to a refund.
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 reduce revenue, and the provision is included in accrued liabilities.
Allowance for Credit Losses on Accounts Receivable—The Company evaluates expected credit losses on 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. Recoveries are 
recognized when received as a reduction to the allowance for credit losses by decreasing bad debt expense. The following

Concentration Risk — During 2024, 2023 and 2022, 8.9%, 8.8% and 9.7% of the Company’s total revenue was 
derived from its top ten customers. As of December 31, 2024 and 2023, 10.4% and 11.3% of the Company’s total accounts 
receivable were derived from its top ten customers. No individual customer accounted for more than 10% of the 
Company’s accounts receivable as of December 31, 2024 and 2023. The Company is dependent on third-party suppliers, in 
some cases single-source suppliers.
Inventories—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. The Company’s industry is characterized 
by rapid product development and frequent new product introductions. Uncertain timing of regulatory approvals, 
variability in product launch strategies and variation in product sales 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 are stated at cost less accumulated depreciation. Depreciation is 
determined using the straight-line method over the estimated useful life. The estimated useful life of leasehold 
improvements is the shorter of the estimated life or the lease term. The estimated useful lives of buildings is 15 to 20 years, 
while furniture, fixtures, computers and office equipment are depreciated from three to seven years. The Company’s RF 
and cryo generators are generally placed with customers that purchase the Company’s disposable products. The estimated 
useful lives of generators are based on anticipated usage by customers and may change in future periods with changes in 
usage or introduction of new technology. Depreciation related to generators is recorded in cost of revenue over three years. 
Maintenance and repair costs are expensed as incurred. The Company assesses the useful lives of property and equipment 
at least annually and retires assets no longer in use. 
Contingent Consideration—Contingent consideration arrangements obligate the Company to pay certain amounts if 
specified future events occur or conditions are met, such as the achievement of certain developmental, commercial or 
regulatory milestones. Contingent consideration obligations incurred in connection with a business combination are 
recorded at fair value on acquisition date and periodically measured, with changes in the estimated fair value reflected in 
operating expense. Contingent consideration arrangements arising from asset acquisitions are recorded within operating 
expenses at the time milestone results are achieved.
Intangible Assets—Technology intangible assets with determinable useful lives are amortized on a straight-line basis 
over the estimated fifteen year period benefited. Patent intangible assets with determinable useful lives are amortized over 
the estimated useful life of five years in a pattern reflecting their estimated economic benefit to the Company. Amortization 
of technology intangible assets is recorded in research and development expense, while amortization of patent intangible 
assets is recorded in cost of revenue. The Company reviews intangible assets for impairment if impairment indicators are 
present using its best estimates based on reasonable and supportable assumptions and projections.
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 performs impairment testing annually on October 1 or more often if impairment indicators are present.
Long-lived Assets—The Company reviews property and equipment and intangible assets, excluding goodwill, for 
impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. 
When such an event occurs, management determines whether there has been impairment by comparing the anticipated 
undiscounted future net cash flows to the related asset's carrying value.

Leases—The Company leases office, manufacturing and warehouse facilities and automobiles under leases that 
qualify as either financing or operating leases, as determined at the inception of the lease arrangement. Lease assets 
represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make 
payments under the lease. Lease assets and liabilities are measured and recorded at the commencement date based on the 
present value of payments over the lease term. 
Lease assets and liabilities include lease incentives and options to extend or terminate when it is reasonably certain 
the Company will exercise that option. The Company uses the implicit rate when readily determinable; however, as most 
leases do not provide an implicit rate, the Company generally uses its incremental borrowing rate. The Company also 
applies the short-term lease recognition exemption, recognizing lease payments in profit or loss, for lease terms of 12 
months or less at commencement and with no option to extend the lease whose exercise is reasonably certain. The 
Company accounts for the lease and non-lease components as a single lease component. Additionally, the portfolio 
approach is applied for operating leases based on the terms of the underlying leases.
Operating leases are included in operating lease right-of-use (ROU) assets and operating lease liabilities, while 
finance leases are included in property and equipment and finance lease liabilities. The short-term portions of lease 
liabilities are included in other current liabilities and current maturities of debt and leases. Operating lease expense is 
recognized on a straight-line basis over the lease term. See Note 10 – Leases for further discussion.
Other Income (Expense)—Other income (expense) consists primarily of foreign currency transaction gains and 
losses generated by settlements of intercompany balances denominated in Euros and customer invoices transacted in 
British Pounds, Australian Dollars and Canadian Dollars.
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 assets and liabilities and their respective tax bases along 
with 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 a 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 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 income tax assets are future 
taxable income, future reversals of existing taxable temporary differences, taxable income in prior carryforward years 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 for a valuation allowance. The Company's valuation allowance 
offsets 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 Company has not reclassified income tax effects of the Tax Cuts 
and Jobs Act within accumulated other comprehensive (loss) income to retained earnings due to its full valuation 
allowance.
Net Loss Per Share—Basic and diluted net loss per share is computed by dividing the net loss available to common 
stockholders 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 exclude the effect of 2,583, 1,668 and 1,292 stock 
options, restricted stock awards, restricted stock units, performance share awards, and performance share units as of 
December 31, 2024, 2023 and 2022 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.
Research and Development Costs—Research and development costs include compensation and other internal and 
external costs associated with the development and research of new and existing products or concepts, preclinical studies, 
clinical trials and studies, related regulatory activities, acquired in-process research and development (IPR&D), as well as 
amortization of technology assets. Research and development costs are expensed as incurred. Clinical trial costs and other

development costs incurred by third parties are expensed as contracted work is performed or over the expected service 
period. Acquired IPR&D expenses reflect the costs of externally developed IPR&D projects acquired in an asset 
acquisition that do not have an alternative future use. Acquired IPR&D is expensed on the acquisition date and future 
expenses to develop the IPR&D projects are recorded in research and development expense as incurred. Milestone 
payments made to third parties in connection with asset acquisitions are expensed as incurred up to the point of regulatory 
approval. 
Advertising Costs—The Company expenses advertising costs as incurred. Advertising expense was $2,817, $1,695 
and $1,233 during the years ended December 31, 2024, 2023 and 2022.
Share-Based Compensation—The Company recognizes share-based compensation expense for all share-based 
payment awards, including stock options, restricted stock awards, restricted stock units, performance share awards (PSAs), 
performance share units (PSUs) and stock purchases related to an employee stock purchase plan, based on estimated fair 
values. The value of the portion of an award that is ultimately expected to vest is recognized as expense over the service 
period. Prior to January 1, 2023, the Company estimated forfeitures at the time of grant and revised them, as necessary, in 
subsequent periods as actual forfeitures differ from those estimates. Effective January 1, 2023, the Company's policy was 
amended to account for forfeitures as they occur rather than estimating at the time of grant, and the effect on income from 
continuing operations and retained earnings is not significant.
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 the fair value is affected by the Company’s stock 
price as well as several subjective assumptions, such as the Company’s expected stock price volatility over the term of the 
awards and actual and projected employee stock option exercise behaviors. The Company estimates the fair value of 
restricted stock awards and restricted stock units based upon the grant date closing market price of the Company’s common 
stock. 
The Company estimates the fair value of PSAs with a performance condition based on the closing stock price on the 
date of grant assuming the performance target will be achieved and may adjust expense over the performance period based 
on changes to estimates of performance target achievement. If such targets are not met or service is not rendered for the 
requisite service period, no compensation cost is recognized, and any recognized compensation cost in prior periods will be 
reversed. For PSAs and PSUs with a market condition, a Monte Carlo simulation is performed to estimate the fair value on 
the date of grant, and compensation cost is recognized over the requisite service period as the employee renders service, 
even if the market condition is not satisfied. The Company’s determination of the fair value is affected by the Company 
and market index stock performance, as defined by the award agreement, at the beginning of the service period and grant 
date; the expected volatility of the Company and market index stock performance over the performance period and the 
correlation coefficient of the daily returns for the Company and market index over the performance period.
The Company also has an employee stock purchase plan (ESPP) covering substantially all U.S. employees of the 
Company. 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 purchase period. Expense is adjusted at the time of stock purchase.
Use of Estimates—The preparation of the financial statements in conformity with accounting principles generally 
accepted in the United States of America (GAAP) requires estimates and assumptions that affect the reported amounts of 
assets and liabilities, including intangible assets, contingent assets and liabilities and the reported amounts of revenue and 
expense during the reporting period. Estimates are based on historical experience, where applicable, and other assumptions 
believed to be reasonable by management. Actual results could differ from those estimates.
Segments—The Company evaluates reporting segments in accordance with FASB ASC 280, “Segment Reporting”. 
The chief operating decision maker for the Company is the Chief Executive Officer. The Company has one business 
activity and operates as one operating segment: the development, manufacture, and sale of devices used by cardiothoracic 
and thoracic surgeons in surgical procedures, designed primarily for the surgical ablation of cardiac tissue, the exclusion of 
the left atrial appendage, and to block pain by temporarily ablating peripheral nerves. These devices are developed and 
marketed to a broad base of medical centers globally. Management considers all such sales to be part of the single 
operating segment. The Chief Executive Officer is regularly provided with consolidated expenses consistent with the 
presented consolidated statements of operations, accompanied by information about revenue by product type and

geographic area, for purposes of allocating resources and evaluating financial performance. Revenue by product type and 
geographic area is included at Note 12 - Revenue. The Company’s long-lived assets are located in the United States, except 
for $4,021 as of December 31, 2024 and $3,432 as of December 31, 2023 located primarily in Europe. 
Fair Value Disclosures—The Company classifies cash equivalents, investments in U.S. government and agency 
obligations, accounts receivable, other current assets, and accounts payable as Level 1. The carrying amounts of these 
assets and liabilities approximate their fair value due to their relatively short-term nature. Investments in corporate bonds, 
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 2 – Fair Value for further information on 
fair value measurements.
Recent Accounting Pronouncements—In November 2024, the FASB issued Accounting Standards Update (ASU) 
2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): 
Disaggregation of Income Statement Expenses”. This guidance requires disaggregation of certain expense captions into 
specified categories in disclosures within the footnotes to the financial statements. The guidance is effective for fiscal years 
beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early 
adoption permitted. The Company is currently evaluating the impact of adopting this standard on its consolidated financial 
statements and disclosures.
2. FAIR VALUE
FASB ASC 820, “Fair Value Measurements and Disclosures”, 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.

The estimated fair value of money market funds transferred from a Level 2 fair value measurement to a Level 1 fair 
value measurement during the year ended December 31, 2024. There were no changes in the levels or methodology of 
measurement of financial assets and liabilities during the years ended December 31, 2023.
Contingent Consideration-Business Combination. The Company's contingent consideration arrangements arising 
from the SentreHEART acquisition obligate the Company to pay certain defined amounts 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. The PMA approval milestone expired on December 31, 
2023, while the achievement period for the reimbursement milestone expires on December 31, 2026. The contingent 
consideration liability is measured by applying the probability weighted scenario method using unobservable inputs, thus 
representing a Level 3 measurement within the fair value hierarchy. The Company continues to assess the projected 
probability of payment during the contractual achievement periods to be remote, resulting in no reported fair value as of 
December 31, 2024 and 2023. 
The Company had no Level 3 fair value measurements using significant other unobservable inputs for contingent 
consideration in the years ended December 31, 2024, 2023 and 2022. 
3. ASSET ACQUISITION
On October 15, 2024, the Company entered into an exclusive licensing agreement (Cooperation Agreement) to co-
develop and commercialize equipment incorporating pulsed field ablation (PFA) technology. The Company paid cash of 
$12,000 for the exclusive license of related intellectual property. The transaction was accounted for as an asset acquisition,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(In Thousands, Except Per Share Amounts)
55

resulting in acquired in-process research and development (IPR&D). The acquired IPR&D was expensed to research and 
development expense as we determined there was no alternative future use of the technologies acquired.
The Cooperation Agreement also requires the Company to pay additional contingent consideration, settled in cash, 
with a maximum payout of $28,000 if all milestones are achieved successfully within the ten-year term as follows:
•Development Milestones - $3,000 to $15,000 for successful delivery of equipment for defined purposes at multiple 
dates within the next two years and is reduced for calendar days lapsed from delivery dates at specified rates.
• Regulatory Approval Milestone - up to $13,000 for First Market Authorization in the United States, as defined in 
the Cooperation Agreement.
The contingent consideration will be expensed when each milestone is paid or becomes payable as a result of 
achievement. As of December 31, 2024, the milestones were not yet achieved and, therefore, there is no financial impact 
during the period. The agreement also contains provisions requiring future royalty payments on devices incorporating co-
developed technology upon commercialization.

9. INDEBTEDNESS
On January 5, 2024, the Company entered into an asset-based credit agreement (Credit Agreement) among the 
Borrowers, JPMorgan Chase Bank, N.A., as administrative agent, and JPMorgan Chase Bank, N.A., as bookrunner and 
lead arranger (JPMCB), and Silicon Valley Bank, a Division of First-Citizen Bank & Trust Company, as Joint Lead 
Arrangers and Joint Bookrunners, and the lenders party thereto (Lenders). The Credit Agreement provides for an asset 
based revolving credit facility (ABL Facility) in an amount of up to $125,000. The Company may request an increase in 
the revolving commitment by up to $40,000 (not to exceed a total of $165,000). Borrowing availability under the ABL 
Facility is based on the lesser of $125,000 or a borrowing base calculation as defined by the Credit Agreement. A portion 
of the ABL Facility, limited to $5,000, is available for the issuance of letters of credit by JPMCB or other financial 
institutions. JPMCB in its sole discretion, may create swingline loans by advancing floating rate revolving loans requested. 
Any such swingline loans will reduce availability under the ABL Facility on a dollar-for-dollar basis. 
At closing, the Company borrowed $61,865. The proceeds of the ABL Facility were used to terminate the 
Company’s outstanding indebtedness and final fee under its then-existing Loan and Security Agreement with Silicon 
Valley Bank (SVB Loan Agreement). Certain prepayment and early termination fees under the SVB Loan Agreement were 
waived at termination. The SVB Loan Agreement terminated on January 5, 2024 and was treated as a debt extinguishment. 
The resulting loss on debt extinguishment is $1,362.
The Credit Agreement has a three-year term, and all outstanding borrowings are due upon maturity of the Credit 
Agreement on January 5, 2027. Through January 2025, the Company's required minimum utilization of the ABL facility is 
40% of the aggregate revolving commitment or $50,000. Subject to customary exceptions and restrictions, the Company 
may voluntarily prepay outstanding amounts under the ABL Facility at any time thereafter without premium or penalty. 
Any voluntary prepayments made will not reduce commitments under the ABL Facility. The Credit Agreement contains 
mandatory prepayment provisions which require prepayment of amounts outstanding under the ABL Facility upon 
specified events or Availability shortfall.
The ABL facility is subject to a facility fee of 0.37% per annum of the daily available revolving commitment and 
paid on a quarterly basis. Outstanding amounts under the Credit Agreement bear interest at a rate per annum equal to, at the 
Company's election: (i) an alternate base rate (ABR) plus an applicable margin or (ii) an adjusted term secured overnight 
financing rate (SOFR) plus an applicable margin. All swingline loans bear interest at a rate per annum equal to the ABR 
plus the applicable margin under the Credit Agreement. Alternate base rate is equal to the greatest of Prime, the NYFRB 
Rate plus 0.50% and Adjusted Term SOFR Rate plus 1.00%. The applicable margin on borrowings will adjust ranging 
1.50% to 1.75% per annum for ABR borrowings and from 2.50% to 2.75% per annum for SOFR term borrowings 
determined by the average historical excess availability. Participation and fronting fees are accrued and paid on a quarterly 
basis. As of December 31, 2024, the effective interest rate on the ABL Facility was 7.33%.
The ABL Facility is secured by the assets of the Company, whether consisting of personal, tangible or intangible 
property, including specified all of the outstanding equity interests of the Company’s direct subsidiaries, subject to 
limitations specified in the Credit Agreement. The Credit Agreement contains customary representations and warranties, 
events of default and financial, affirmative and negative covenants for facilities of this type, including but not limited to 
financial covenants relating to a fixed charge coverage ratio, a minimum liquidity requirement and a minimum excess 
availability requirement, and restrictions on indebtedness, liens, investments and acquisitions, asset dispositions, specified 
agreements, restricted payments and prepayment of certain indebtedness.

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

11.  COMMITMENTS AND CONTINGENCIES
License Agreements. In 2024, we entered into an exclusive licensing agreement (Cooperation Agreement) to co-
develop and commercialize equipment incorporating pulsed field ablation (PFA) technology. The Company paid cash of 
$12,000 for the exclusive license of related intellectual property. The Cooperation Agreement also requires the Company to 
pay additional contingent consideration, settled in cash, with a maximum payout of $28,000 if all milestones are achieved 
successfully within the ten-year term. The agreement also contains provisions requiring future royalty payments on devices 
incorporating co-developed technology upon commercialization. See Note 3 - Asset Acquisition for further information.
The Company had been party to a license agreement that required payments of 5% of specified product sales. In May 
2023, the Company entered into an agreement that terminated the license agreement and the Company's obligations to 
make royalty payments. See Legal section below for additional information. There was no royalty expense for the year 
ended December 31, 2024. Royalty expense was $1,333 and $3,264 for the years ended December 31, 2023 and 2022. 
Purchase Commitments. The Company enters into various purchase arrangements related to its manufacturing and 
research and development activities. In the ordinary course of business, these agreements generally include terms that allow 
cancellation. In 2022, the Company entered into a clinical trial management agreement for the LeAAPS clinical trial. The 
terms of the agreement require payments upon achievement of various enrollment and project milestones over the 
estimated ten-year term, yet the agreement may be terminated early for any reason. Furthermore, we incur additional 
variable costs, including pass through costs from clinical trial sites. Payments made under this agreement were $12,471, 
$5,636, and $1,539 for the years ended December 31, 2024, 2023, and 2022.
Legal. The Company may, from time to time, become a party to legal proceedings which are subject to many 
uncertainties. Litigation and administrative proceedings over patent and other intellectual property rights are common in 
our industry, as are requests for information related to interactions with medical professionals. Accordingly, the financial 
impact of ultimate resolutions from legal proceedings may not be known for extended periods of time and are not 
predictable with assurance. A liability is established once management determines a loss is probable and an amount can be 
reasonably estimated. The Company recognizes income from a favorable resolution of legal proceedings when the 
associated cash or assets are received. 
On February 7, 2025, representatives for former securityholders of SentreHEART, Inc. filed a complaint in the 
Delaware Court of Chancery naming the Company as a defendant. The Company acquired SentreHEART, Inc. pursuant to 
a merger agreement dated August 11, 2019. The merger agreement provides for contingent consideration to be paid upon 
achievement of specified PMA and CPT reimbursement milestones by specified dates. The complaint alleges breach of 
contract and a related claim for breach of the implied covenant of good faith and fair dealing resulting from the Company's 
alleged failure to use commercially reasonable efforts to obtain premarket approval from FDA for the LARIAT System. 
The complaint seeks damages in the amount of the original PMA and CPT reimbursement milestones of up to $260,000 
plus interest. The Company intends to vigorously defend this claim. A liability has not been recognized related to this 
matter because any potential loss is not currently probable or reasonably estimable.
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. In March 2021, USDOJ informed the Company that its investigation was based on a 
lawsuit brought on behalf of the United States and various state and local governments under the qui tam provisions of 
federal and certain state and local False Claims Acts. Although the USDOJ and all of the state and local governments 
declined to intervene, the relator continued to pursue the case. During the third quarter of 2022, the relator filed a Fourth 
Amended Complaint, which alleged that the Company paid illegal kickbacks. In September 2024, the District Court 
granted the Company's motion to dismiss the Fourth Amended Complaint and denied the relator's request for leave to 
further amend the complaint. 
On August 23, 2022, the Cleveland Clinic Foundation (Clinic) and IDx Medical, Ltd. (IDx) filed a Demand for 
Arbitration against the Company with the American Arbitration Association (AAA), alleging that the Company breached 
certain provisions of the 2003 License Agreement, among the Company, Clinic and IDx (License Agreement). Clinic and 
IDx alleged that the Company did not include the revenues from sales of certain products in its royalty payments due under 
the License Agreement, and the Company did not provide related notices required under the License Agreement. The 
Company filed its Answering Statement and Counterclaims to the allegations in September 2022, denying each claim. In

May 2023, the Company entered into an Assignment and Agreement Regarding IDx and CCF Intellectual Property 
(Assignment Agreement) with Clinic and IDx. Pursuant to the Assignment Agreement, during the second quarter of 2023, 
the Company made a one-time payment of $33,400 to Clinic and IDx for the acquisition of patents and other intellectual 
property. The Assignment Agreement also required dismissal of the arbitration and release of payment for royalty 
obligations due to Clinic and IDx under the License Agreement after March 31, 2023. The amount paid, together with 
transaction costs, was allocated between the acquired intangible asset, the release of payment for royalty obligations and 
the settlement of the dispute. The intangible asset was assigned a value of $30,000 and is being amortized over an 
estimated useful life of 5 years. The release of the royalty obligations was valued at $432. The remaining $3,088 was 
allocated to the settlement and is included in selling, general and administrative expenses for the twelve months ended 
December 31, 2023. 
During the first quarter of 2023, the Company entered into a legal settlement of $7,500 in connection with the 
settlement of claims filed against a competitor. The Company recorded a $7,500 gain for the twelve months ended 
December 31, 2023 for the proceeds received as a reduction to selling, general and administrative expenses. 
12.  REVENUE
The Company develops, manufactures and sells devices designed primarily for surgical ablation of cardiac tissue, 
exclusion of the left atrial appendage, and temporarily blocking pain by ablating peripheral nerves. These devices are 
marketed to a broad base of medical centers globally and primarily used by cardiothoracic and thoracic surgeons. 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.

13.  INCOME TAXES 
The Company files federal, state and foreign income tax returns in jurisdictions with varying statutes of limitations. 
The Company uses 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's valuation allowance offsets 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:

amortize research and experimental expenditures for tax purposes over five or fifteen years, depending on where research is 
conducted. The Company has federal net operating loss carryforwards of $216,156 which expire between 2025 and 2037 
and $175,758 which have no expiration. The Company has state and local net operating loss carryforwards of $251,677 
which expire between 2025 to 2044. A portion of the Company’s federal and state net operating loss carryforwards are 
subject to certain limitations under Internal Revenue Code Sections 382 and 383. The Company has federal research and 
development credit carryforwards of $18,181 which expire between 2025 and 2044. Additionally, the Company has foreign 
net operating loss carryforwards of approximately $79,662 which have no expiration.

The Company’s pre-tax book loss for domestic and international operations was $36,983 and $6,691 for 2024, 
$17,822 and $12,025 for 2023, and $38,008 and $8,190 for 2022. 
The Company had undistributed earnings of foreign subsidiaries of approximately $609 at December 31, 2024. The 
Company does not consider these earnings as permanently reinvested and has determined that no current and deferred taxes 
are required on such amounts.
The Company's federal, state, local and foreign tax returns are routinely subject to review by various taxing 
authorities. Federal income tax returns for periods beginning in 2021 are open for examination. Generally, state and foreign 
income tax returns for periods beginning in 2020 are open for examination. However, taxing authorities have the ability to 
audit 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. The Company has not accrued any interest and penalties related to unrecognized 
income tax benefits as a result of offsetting net operating losses. However, if required, the Company will recognize interest 
and penalties within income tax expense and within the related tax liability. 
A reconciliation of the change in federal and state unrecognized tax benefits for 2024, 2023 and 2022 is presented 
below:

The balance of unrecognized tax benefits at December 31, 2024, 2023 and 2022 includes $1,514, $1,672 and $1,762 
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, 2024.

14.  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- or post-tax annual compensation 
up to specified maximums under the Internal Revenue Code. During the years ended December 31, 2024, 2023 and 2022, 
the Company matching contribution was 50% on the first 8% of employee contributions to the 401(k) Plan. The 
Company’s matching contributions in 2024, 2023 and 2022 were $5,477, $4,949 and $4,447. 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 in 2024, 2023 or 2022. The Company also provides retirement benefits for employees of its 
foreign subsidiaries. Total contributions to foreign retirement plans were $702, $503 and $446 in 2024, 2023 and 2022.
15.  EQUITY COMPENSATION PLANS
The Company has two share-based incentive plans: the 2023 Stock Incentive Plan (2023 Plan) and the 2018 
Employee Stock Purchase Plan (ESPP). 
Stock Incentive Plan
Under the 2023 Plan, the Board of Directors may grant restricted stock awards or restricted stock units (collectively 
RSAs), nonstatutory stock options, performance share awards, performance share units or stock appreciation rights to 
Company employees, directors and consultants, and may grant incentive stock options to Company employees. The 
Compensation Committee of the Board of Directors, as the administrator of the 2023 Plan, 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, 2024, 4,087 shares of common stock had been reserved for issuance under the 
2023 Plan and 2,480 shares were available for future grants. The Company issues registered shares of common stock for 
stock option exercises, restricted stock grants and performance award grants. 
The following table summarizes total share-based compensation expense related to employees, directors and 
consultants for 2024, 2023 and 2022. The expense was allocated as follows:

Performance Share Awards and Units. The award agreements for the performance share awards (PSAs) provide 
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 with respect to specified targets at the end of the three-year performance period. PSAs have two weighted 
performance targets: (i) the Company’s compound annual revenue growth rate (CAGR), a performance condition and (ii) 
relative total shareholder return (TSR), a market condition, both measured over the three-year performance period. TSR is 
measured against the NASDAQ Health Care Index constituents and the 20-trading-day average stock price prior to the start 
and end of the performance period. PSAs outstanding as of December 31, 2024 have payout opportunities ranging from 0% 
to 300% of the target amount. PSAs granted in 2022 are weighted 60% on the CAGR performance target and 40% on the 
TSR performance target. PSAs granted since 2023 are weighted 75% on the CAGR performance target and 25% on the 
TSR performance target. These ranges are used to determine the number of shares that will be issuable when the award 
vests. The performance and market condition payouts will be determined independently and accumulated to determine the 
total payout for the three-year performance period, subject to the maximum payout defined in the PSA agreements. 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. 
During 2024, the Compensation Committee approved the grant of Performance Share Units (PSUs) to the Company's 
President and Chief Executive Officer. The award agreement for the PSUs provides that each PSU that vests represents the 
right to receive one share of the Company's common stock at the end of the measurement periods. The number of shares 
that vest and are issued are based on the attainment of specified stock prices over three measurement periods over a four 
year period. PSUs vest in defined tranches on the last day of the measurement period, subject to a market vesting condition 
upon the simple moving average of the closing share price during the 60 consecutive calendar days immediately prior to 
Table of Contents

and including the measurement period date. PSUs that do not vest on the last day of the measurement period are forfeited. 
PSUs may vest following termination of service by reason of death or disability or change in control based on the 
performance criteria achieved as of the termination date or in connection with the change in control as specified in the 
award agreement.

The total fair value of performance share awards vested during 2024, 2023 and 2022 was $3,459, $4,955 and $5,185. 
In determining compensation expense, the fair value of performance share awards with a performance condition is 
based on the market value of the Company’s stock on the grant date of the awards. The fair value of performance share 
awards and performance share units with a market condition is estimated on the grant date using a Monte Carlo simulation 
and includes the following assumptions:

The expected term is estimated as the remaining performance period at the grant date. Expected volatility is estimated 
based on the Company and daily trading prices of the market index, adjusted for dividends and stock splits over the 
remaining performance period. The risk-free interest rate is based upon the United States Constant Maturity yield curve at the 
time of grant for the expected term of the performance share awards. Based on the assumptions above, the weighted average 
estimated grant date fair value per share and expense was as follows:

In determining compensation expense, the fair value of restricted stock awards and restricted stock units is based on 
the market value of the Company’s stock on the grant date of the awards. The weighted average estimated grant date fair 
value per share and expense was as follows:

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 2024, 2023 and 2022, $1,022, $2,316 and $1,816 in cash proceeds from 
the exercise of stock options were included in the Consolidated Statements of Cash Flows.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND 
FINANCIAL DISCLOSURE 
None. 
ITEM 9A. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures 
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 or twelve months ended December 31, 2024 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, 2024. 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, 2024. 
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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 
To the stockholders and the Board of Directors of 
AtriCure, Inc.
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, 2024, 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, 2024, 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, 2024, of the Company 
and our report dated February 14, 2025, 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.
