PART I

Item 1. Business.

Overview

We are a commercial-stage medical technology company transforming organ transplant therapy for end-stage organ failure patients across multiple 
disease  states.  We  developed  the  OCS  to  replace  a  decades-old  standard  of  care  that  we  believe  is  significantly  limiting  access  to  life-saving  transplant 
therapy  for  hundreds  of  thousands  of  patients  worldwide.  Our  innovative  OCS  technology  replicates  many  aspects  of  the  organ’s  natural  living  and 
functioning environment outside of the human body. As such, the OCS represents a paradigm shift that transforms organ preservation for transplantation 
from a static state to a dynamic environment that enables new capabilities, including organ optimization and assessment. We have also developed our NOP, 
an innovative turnkey solution to provide outsourced organ retrieval, OCS organ management and logistics services, to provide transplant programs in the 
United  States  with  a  more  efficient  process  to  procure  donor  organs  with  the  OCS.  Our  logistics  services  include  aviation  transportation,  ground 
transportation, and other coordination activity. We believe the use of the OCS combined with the NOP has the potential to significantly increase the number 
of organ transplants and improve post-transplant outcomes. 

We designed the OCS to be a platform that allows us to leverage core technologies across products for multiple organs. To date, we have developed 
three OCS products, one for each of heart, lung and liver transplantations, making the OCS the only FDA approved, portable, multi-organ, warm perfusion 
technology platform. All three of our products, OCS Heart, OCS Lung and OCS Liver, have received Pre-Market Approval, or PMA, from the Food and 
Drug Administration, or FDA, for both organs donated after brain death, or DBD organs, and organs donated after circulatory death, or DCD organs. 

Incidence  of  end-stage  organ  failure  has  been  rapidly  rising  worldwide  due  to  demographic  trends  that  contribute  to  chronic  diseases.  Organ 
transplantation  is  the  treatment  of  choice  for  addressing  end-stage  organ  failure  due  to  its  positive  clinical  outcomes  and  favorable  health  economics. 
However, transplant volumes have been significantly restricted by the limitations of cold storage, the standard of care for solid organ transplantation. Cold 
storage is a rudimentary approach to organ preservation in which a donor organ is flushed with cold pharmaceutical solutions, placed in a plastic bag on top 
of ice and transported in a cooler. Cold storage subjects organs to significant injury due to a lack of oxygenated blood supply, or ischemia, does not allow 
physicians  to  assess  organ  viability  and  lacks  the  ability  to  optimize  an  organ’s  condition  once  it  has  been  retrieved  from  the  donor.  Time-dependent 
ischemic injury has been shown to result in short- and long-term post-transplant clinical complications and, together with the inability to assess or optimize 
organs, contributes to the severe underutilization of donor organs. With the use of cold storage, the majority of lungs and hearts donated after brain death go 
unutilized, and almost no available lungs and hearts donated after circulatory death are utilized.

We developed the OCS to comprehensively address the major limitations of cold storage. The OCS is a portable organ perfusion, optimization and 
monitoring system that utilizes our proprietary and customized technology to replicate near-physiologic conditions for donor organs outside of the human 
body. We designed the OCS technology platform to perfuse donor organs with warm, oxygenated, nutrient-enriched blood, while maintaining the organs in 
a  living,  functioning  state;  the  lung  is  breathing,  the  heart  is  beating  and  the  liver  is  producing  bile.  Because  the  OCS  significantly  reduces  injurious 
ischemic time on donor organs as compared to cold storage and enables the optimization and assessment of donor organs, it has demonstrated improved 
clinical outcomes relative to cold storage and offers the potential to significantly improve donor organ utilization.

We developed the NOP to provide additional capabilities to transplant centers for the complicated organ procurement process that often requires 
resources and logistics beyond a transplant center’s existing capabilities and capacity, thereby limiting the number of organs the transplant center may be 
able to retrieve. Our NOP provides trained organ procurement surgeons, clinical specialists and transplant coordinators that provide an end-to-end clinical 
solution using our OCS technology. In 2023, we enhanced our NOP offering to include logistics services with the addition of a logistics team to expand our 
transportation logistics capabilities. Our logistics services include aviation transportation, ground transportation, and other coordination activity. Our NOP 
provides transplant centers with the ability to utilize the OCS to procure and transplant more organs for their patients than they would otherwise be able to 
do without increasing their own staff.

On  August  16,  2023,  we  acquired  Summit  Aviation,  Inc.  and  Northside  Property  Group,  LLC,  or  together  Summit.  Summit  was  a  charter  flight 
operator based in Bozeman, Montana. The acquisition enabled us to add aircraft transportation services to our NOP and become a comprehensive national
provider of donor organ retrieval and delivery in the United States. We have also acquired 13 fixed-wing aircraft to transport donor organs as part of the 
services offered under our NOP. We intend to acquire additional fixed-wing aircraft as we scale our fleet of aircraft to reduce our dependence on third party 
transportation providers. 

We believe the OCS and the NOP drive significant benefits to all stakeholders in the field of organ transplantation. For patients, we believe the OCS 
and the NOP provide additional access to life-saving transplants and allow for quicker recovery following transplantation. For hospitals, we believe the 
OCS and NOP provide a means to increase transplant volume, treat more patients, enhance provider status and improve transplant program economics. 
Finally, we believe the OCS and NOP provide payors with a more cost-effective treatment for end-stage organ failure and reduces exposure to significant 
post-transplant complication costs and extended hospital stays.

Our OCS products and NOP services are reimbursed in the United States through existing, standard commercial transplant billing mechanisms. The 
Medicare program and private payors had been providing reimbursement for the OCS Lung, OCS Heart and OCS Liver during the U.S. pivotal trials and 
have continued providing reimbursement for our products and services following FDA approval. We are in the process of seeking long-term reimbursement 
for our products outside of the United States.

Our  corporate  headquarters,  manufacturing  and  clinical  training  facilities  are  located  in  Andover,  Massachusetts.  We  also  have  a  geographically 
distributed team in the United States supporting our NOP. We have additional distribution and commercial operations in Europe. As of December 31, 2023, 
we had 584 employees, most of whom were full-time and located in the United States. We generated $241.6 million, $93.5 million and $30.3 million of 
total revenue during the years ended December 31, 2023, 2022 and 2021, respectively, representing year-over-year growth of 158.5% and 208.8% in 2023 
and 2022, respectively. Our business model is characterized by a high level of recurring revenue, which is derived primarily from sales of our single-use, 
organ-specific disposable sets that are required for each transplant using the OCS as well as services provided to transplant centers by our NOP.

Our Competitive Strengths

We believe the continued growth of our company will be driven by the following competitive strengths:

•

•

•

•

Only FDA approved, portable, multi-organ, warm perfusion platform
Our Organ Care System is the only FDA approved portable, multi-organ, warm perfusion device on the market. Portability is a critical aspect 
in reducing the ischemic injury to the organ before transplantation, thereby reducing post-transplant complications and allowing the utilization 
of more organs for transplant. The multi-organ platform allows for the standardization of use across transplant programs.

National OCS Program
We developed our NOP to provide transplant programs with a more efficient process to procure donor organs with the OCS. As we expect the 
number of transplants to increase and the retrieval distance to extend, we believe the field will need alternatives to the current model in which 
the recipient transplant center sends its team to the donor site for retrieval. Our NOP provides a turnkey solution that leverages the technical 
advantage of the OCS and provides transplant centers with a more efficient way to increase their volume of transplants without significantly 
increasing resources.

Transportation Logistics of the NOP
Transporting  organs,  clinical  staff  and  medical  technology  in  the  field  of  organ  transplant  is  very  challenging.  Donor  organs  may  become 
available at almost any hospital at any time. The donor organ must be retrieved and transported to allocated recipients in a timely manner while 
protecting the organ from ischemic injury. The donor site may not be easily accessible and the distance to travel from donor to recipient may be 
very long. The expansion of our NOP to provide our own transportation logistics services, including 100% owned and operated private aircraft 
dedicated to organ retrieval, further improves the efficiency of utilizing the NOP as a complete solution for organ procurement. 

Significant body of strong clinical evidence
In order to receive FDA approval for our PMA products, we have conducted a very large number of clinical trials with very large numbers of 
patient participants, with the results of these trials published in leading medical journals. We also continue to collect clinical data through post-
market registries for all of our products and plan to continue to provide the scientific results of these registries to the clinical user community.

•

Strong relationship with the clinical transplant community
The transplant community is highly concentrated in the leading academic medical centers around the world. We have developed strong clinical 
relationships with many of these centers through their participation in our clinical trials and their commercial utilization of our products and 
services. In addition, many transplant surgeons at our clinical trial locations may have moved to new centers, bringing their OCS experience 
with them and allowing our relationships to grow to these new centers.

Expertise in transplant reimbursement and billing   
The OCS has been reimbursed by the Centers for Medicare & Medicaid Services, or CMS, and private insurers during our clinical trials and 
continues to be reimbursed in the commercial setting. Since our customers have been billing for reimbursement for many years, we have 
developed a high degree of expertise in the area of transplant reimbursement and appropriate billing of insurers. We provide advice and best 
practices to our customers in compliance with laws and regulations.

Strong research and development capabilities and comprehensive intellectual property portfolio 
We have a long history and broad experience in the development of warm machine perfusion for organ preservation. During the life of our 
OCS  technology  platform  we  have  continued  to  add  technological  and  usability  enhancements  to  our  devices.  In  the  future,  we  intend  to 
develop newer versions of the technology that continue to improve the ease of use, portability, and capability of the products. 

Organ Transplant Therapy Benefits and Challenges

We believe organ transplantation is the most effective treatment for end-stage organ failure in terms of both clinical outcomes and health economics. 
Organ  transplant  provides  the  longest  life  expectancy  and  best  quality  of  life  compared  to  other  therapies  for  end-stage  organ  failure.  For  example,  the 
therapeutic options for end-stage heart failure include optimum medical management with pharmaceutical treatments, or OMM, mechanical support with a 
left ventricular assist device, or LVAD, and heart transplantation. Heart transplantation is associated with materially longer survival rates as compared to 
OMM and LVADs, which are either used as a bridge to transplant or as destination therapy, an alternative to transplant. These improved survival rates, in 
turn, result in favorable economics for transplantation on the basis of quality-adjusted life years.

However, organ transplant therapy faces two major challenges. First, despite the large and growing incidence of organ failure worldwide, and the 
significant  clinical  and  economic  benefits  of  organ  transplantation,  the  number  of  transplants  severely  lags  demand  due  to  the  limitations  of  traditional 
methods  of  organ  preservation  prior  to  transplantation.  Second,  a  high  rate  of  post-transplant  clinical  complications  needs  to  be  reduced  to  improve 
outcomes and lower costs.

The use of cold static storage for preservation of donor organs contributes to these challenges in three ways:

•

•

Subjects the donor organs to severe time-dependent ischemic injury

Cold  storage  deprives  the  organs  from  oxygen,  resulting  in  time  dependent  injury  (ischemia).  This  injury  correlates  with  post-transplant 
complications and restricts the viable time for organ procurement and transplant, which limits the time and distance possible between donor and 
recipient and results in low utilization of the donor pool and limits the number of transplant procedures performed annually.

No organ optimization capability

Given  the  non-physiologic  environment,  cold  storage  does  not  allow  for  any  therapeutic  interventions  to  optimize  the  condition  of  the  donor 
organs. This further limits utilization of available donor organs for transplantation and could negatively impact post-transplant outcomes. It is 
well  demonstrated  that  donor  organs  benefit  from  some  form  of  optimization  to  replenish  depleted  levels  of  substrates,  hormones,  and 
electrolytes that are significantly altered or used up during the donation process. 

•

No organ viability assessment capability 

During cold storage, the organs are not physiologically active, nor functioning; thus, there are no means for evaluating the suitability of these 
organs  for  transplantation.  This  further  limits  utilization  of  available  organs  as  donor  populations  worldwide  are  growing  older  and  have 
concomitant risk factors that benefit from sophisticated diagnostic evaluation capabilities to predict whether the donor organ is suitable and safe 
to transplant.

Our Technology and Solution

We developed the OCS to comprehensively address the major limitations of cold storage. The OCS is a portable organ perfusion, optimization and 
monitoring system that utilizes our proprietary and customized technology to replicate near-physiologic conditions for donor organs outside of the human 
body.  The  OCS  was  designed  to  perfuse  donor  organs  with  warm,  oxygenated  and  nutrient-enriched  blood,  while  maintaining  the  organs  in  a  living, 
functioning state; the lung is breathing, the heart is beating and the liver is producing bile. As such, the OCS represents a paradigm shift that transforms 
organ  preservation  for  transplantation  from  a  static  state  to  a  dynamic  environment  that  enables  new  capabilities,  including  organ  optimization  and 
assessment. 

The OCS Technology Platform

We developed the OCS, the first and only FDA approved portable, multi-organ, warm perfusion platform, to leverage proprietary core technologies 
across multiple organs. For each OCS product, we supplement the platform with organ-specific, customized and proprietary technologies. To date, we have 
developed three OCS products, one for each of lung, heart and liver transplantation. We have initiated the development of the next generation multi-organ 
platform to improve the usability, incorporate new technology and automation, and facilitate the use of OCS in our NOP. 

Each OCS product consists of three primary components customized for each organ:

•

•

•

OCS Console: The OCS Console is a highly portable electromechanical medical device that houses and controls the function of the OCS and 
is designed to fit in the current workflow for organ transplantation.

OCS Perfusion Set: The OCS Perfusion Set is a sterile, biocompatible single-use disposable set that stores the organ and circulates blood. The 
OCS Perfusion Set includes all accessories needed to place the organ on the system.

OCS  Solutions:  The  OCS  Solutions  are  a  set  of  nutrient-enriched  solutions  used  with  blood  to  replenish  depleted  nutrients  and  hormones 
needed to optimize the organ’s condition outside of the human body.

The OCS technology platform is equipped with the following core technologies that we designed to comprehensively address the limitations of cold 

storage and improve transplant outcomes:

•

•

•

•

proprietary pulsatile blood pump to simulate beating heart perfusion in organs outside of the human body;

proprietary software-controlled titanium blood warmer to maintain blood at body temperature while maximizing portability;

gas exchanger to maintain organ oxygenation outside of the human body;

customized hemodynamics sensors to monitor and assess organ function outside of the human body;

6

 
 
 
 
•

•

•

proprietary software-controlled, miniaturized, electromechanical system with universal power supply and hot-swappable batteries to 
maximize portability and travel distance for organ retrieval;

proprietary wireless monitor and control software to provide an intuitive user interface for monitoring critical organ function; and

customized carbon fiber OCS console structure to reduce the overall weight of the system and maximize portability.

Key Advantages of the OCS Platform

We believe the OCS platform provides significant benefits relative to cold storage:

•

•

•

Significant reduction in ischemia
Decreases current time and distance limitations on organ transport while also increasing the currently limited time period for retrieval during 
which  high  quality  transplant  outcomes  can  reliably  be  obtained.  This  maximizes  organ  utilization  and  enables  increased  access  to  organ 
transplantation, while also meaningfully improving post-transplant outcomes.

Enables organ optimization outside of the human body
Allows therapeutic optimization of donor organs from the damaging conditions of brain and circulatory death using clinically proven and safe 
modalities, thus significantly improving donor organ utilization and patient outcomes.

Allows for organ viability assessment
Enables  diagnostic  evaluation  of  the  donor  organ  using  currently  acceptable  clinical  standards  to  evaluate  the  organ’s  suitability  for 
transplantation and to maximize the post-transplant outcomes.

We believe that by comprehensively addressing the three limitations of cold static storage, the use of the OCS will allow for increased utilization of 

donor organs and improve post-transplant outcomes.

Benefits of the OCS Platform for Key Stakeholders

We believe the OCS platform provides significant benefits to key constituents across the transplant continuum.

Value to Patients

We believe the OCS increases patients’ access to what we believe is the best treatment option for end-stage organ failure, which results in improved 
quality of life and longer life expectancy. In addition, we believe improved clinical outcomes from use of the OCS will allow patients to recover more 
quickly following a transplant.

Value to Providers

We  believe  the  OCS  allows  providers  to  improve  clinical  outcomes  and  increase  the  number  of  patients  who  receive  organ  transplants. 
Improvements  in  clinical  outcomes  could  enable  providers  to  meet  the  CMS  post-transplant  survival  metrics  required  for  reimbursement  coverage  and 
improve the overall financial profile of their transplant programs. In addition, we believe the increase in transplant volumes enabled by the OCS will help 
providers achieve “Center of Excellence” designations with payors and thus drive significant revenue growth for their transplant programs.

Value to Payors

We believe organ transplantation is a cost-effective treatment for end-stage organ failure as it provides the longest life expectancy, and better quality 
of life, compared to other treatments like mechanical support or medical therapy. We believe the OCS will enable payors to benefit from these favorable 
health economics and limit their exposure to the high cost of severe post-transplantation complications and extended hospital stays.

Our Strategy

We are committed to our goal of transforming organ transplantation with our OCS platform by establishing the OCS as the standard of care for solid 

organ transplantation and thereby increasing the utilization of donor organs and improving clinical outcomes.

The key elements of our strategy are:

•

•

•

•

Grow the adoption of the OCS at existing transplant center customers and expand the number of centers utilizing OCS and NOP. We 
are focused on driving adoption of the OCS and NOP at leading, high volume transplant programs as well as expanding utilization to medium 
and smaller centers that can utilize OCS and NOP to provide transplants to more patients. 

Grow our NOP, a turnkey solution to provide outsourced organ retrieval, OCS organ management and logistics services, to provide 
transplant programs with a more efficient process to procure donor organs with the OCS. Our NOP leverages our clinical, logistical and 
transportation capabilities to provide access to and use of the OCS for transplant centers throughout the United States. We believe this program 
has the potential to accelerate adoption of the OCS, maximize utilization of donor organs for transplantation and, by standardizing the quality 
of use of the OCS, deliver better clinical outcomes.

Develop  the  next  generation  OCS  technology  platform  to  improve  user  experience  and  facilitate  our  NOP.  We  have  initiated  the 
development of the next generation multi-organ platform to improve the usability, incorporate new technology and automation, and facilitate 
the use of OCS in our NOP. In addition, in August 2023, we acquired certain assets related to lung and heart perfusion technology from Bridge 
to Life, and we intend to further develop these technologies to expand our product offerings and indications for organ transplantation.

Expand internationally by accessing national reimbursement for OCS in key European countries. We have begun the development of 
required  comprehensive  material  for  various  national  healthcare  systems  throughout  Europe.  We  believe  international  expansion  will  be  an 
additional growth driver for us in the long term.

Commercialization

We commercialize our products through two channels: our NOP and a direct acquisition model. Our NOP enables transplant centers to outsource the 
retrieval, organ management and transportation logistics process to our trained organ procurement surgeons, clinical specialists and transplant and logistics 
coordinators using our OCS products. Our offering allows the transplant center to focus their internal resources on the transplant surgery and patient care. 
Utilizing our NOP saves the transplant center from investing in additional resources to support higher volumes and longer distance retrievals. Since the 
launch of the NOP, our sales of the OCS have primarily been through the NOP.

Our direct acquisition model is provided to transplant centers to train their own teams for retrieval and organ management on the OCS. Customer 
users are certified on the use of OCS at our training facility. Customers in the direct acquisition channel keep inventory of OCS disposables available and 
order replenishment as they are used. All of our international customers and a small number of our U.S. customers purchase our OCS products through the 
direct acquisition model. 

Reimbursement

Medicare’s  reimbursement  for  organ  transplant  procedures  is  well-established  and  involves  two  payment  mechanisms.  The  first  is  the  inpatient 
hospital prospective payment system, which reimburses the transplant hospital for operating costs incurred during the inpatient stay in which the transplant 
procedure is performed. The payment for this stay is determined by the Medicare Severity-Diagnosis Related Group, or MS-DRG, into which the case is 
assigned. The second mechanism involves a separate payment, in addition to the MS-DRG-based payment, for organ acquisition costs, which include organ 
preservation  and  transportation  costs.  Medicare  reimburses  hospitals  for  allowable  organ  acquisition  costs  on  a  reasonable  cost  basis.  The  OCS  is 
reimbursed under this second mechanism.

For Medicaid transplant recipients, reimbursement to a transplant hospital for the incurred cost of the OCS is determined based on the applicable 
state Medicaid program. Some states establish a global payment for the transplant and organ acquisition costs, and some states have separate payments for 
the inpatient stay based on the MS-DRG system and for organ acquisition costs. Private insurers typically have agreements as to how they reimburse for the 
transplant costs and the organ acquisition costs, 

8

 
which may be through a global payment for both, or a payment for the transplant and a separate mechanism for paying for organ acquisition costs. Nearly 
half of U.S. lung, heart and liver transplants are covered under the Medicare and Medicaid programs, with the remainder being reimbursed through private 
payors.

Medicare and private payors provided reimbursement for the OCS Lung, OCS Heart and OCS Liver during the U.S. pivotal trials and have provided 
reimbursement for the OCS Lung, OCS Heart and OCS Liver following their FDA approvals. This has established multiple years of billing precedent. We 
believe  these  established  methods  will  continue  to  facilitate  commercial  reimbursement  for  the  OCS  Lung,  OCS  Heart  and  OCS  Liver.  Reimbursement 
outside of the United States follows a similar overall structure; however, reimbursement decisions are required in each individual country and may require 
national  health  systems  to  review  and  approve  OCS  reimbursement  for  each  organ-specific  product.  Currently,  national  healthcare  systems  do  not 
reimburse transplant centers for the use of the OCS and reimbursement in international markets may require us to undertake additional clinical studies. 
However, international hospitals using the OCS currently pay for the OCS from their hospital budget or charitable funds. We are in the process of seeking 
long-term reimbursement for our OCS products in several jurisdictions.

Clinical Evidence

The lead transplant surgeons at transplant centers are clinically focused and rely primarily on clinical evidence to drive changes in their practice of 
organ transplantation. We have developed a substantial body of global clinical evidence to support our FDA PMA approvals and PMA submissions for the 
OCS for lung, heart and liver transplantation. Many of these clinical trials and studies have been published in peer-reviewed clinical journals. Our clinical 
trials have evaluated the use of the OCS for transplantation of organs that meet the current criteria for organ transplantation, as well as organs that would 
otherwise go unutilized from DBD and DCD donors. We believe the results of our clinical trials across lung, heart and liver transplantation may support the 
potential of the OCS in improving clinical outcomes and increasing utilization of available donor organs.

The results of our clinical trials are summarized in the images below.

Intellectual Property 

Patents and Trade Secrets

We  rely  on  a  combination  of  patent,  trademark,  copyright,  trade  secret  and  other  intellectual  property  laws,  nondisclosure  and  assignment  of 
inventions agreements and other measures to protect our intellectual property. Our patent portfolio includes patents and patent applications that we own or 
license from third parties.

As of December 31, 2023, our owned and licensed patent portfolio consisted of approximately 400 issued patents and pending patent applications 
worldwide, including in the United States, Australia, Europe, Canada, China, Israel, New Zealand and Japan. Our owned portfolio includes patents and 
applications related to one or more of the OCS Lung, OCS Heart, OCS Liver and solutions. In the United States, our owned portfolio includes about 45 
issued patents and 13 pending applications. Outside the United States, our owned portfolio includes about 288 issued patents and 54 pending applications. 
Issued patents in our portfolio are expected to expire between 2025 and 2038, excluding any potential additional patent term for patent term adjustments or 
patent term extensions, if applicable. If granted, the pending U.S. and foreign patent applications in our portfolio are expected to expire between 2025 and 
2043, excluding any potential additional patent term for patent term adjustments or patent term extensions, if applicable.

10

 
 
 
 
 
As of December 31, 2023, our patent portfolio relating to the OCS Lung or lung transplantation technology includes families comprised of patents 
and  patent  applications  with  claims  that  are  generally  directed  to  certain  methods  and  systems  for  preserving  a  lung  ex  vivo  using  both  perfusion  and 
ventilation.  Such  patents  are  issued  in  the  United  States,  Australia,  Belgium,  Canada,  China,  Denmark,  Europe,  France,  Germany,  Ireland,  Israel,  Italy, 
Japan, Hong Kong, Netherlands, New Zealand, Spain, Sweden, and United Kingdom, and patent applications are pending in the United States, Australia, 
Canada, China, Europe, Hong Kong, Israel, Japan and New Zealand. These patents, and any patents issued from pending patent applications, are expected
to expire in 2043, excluding any potential additional patent term for patent term adjustments or patent term extensions, if applicable. 

As of December 31, 2023, our patent portfolio relating to the OCS Heart or heart transplantation technology includes families comprised of patents 
and patent applications with claims that are generally directed to certain methods and systems for preserving a heart ex vivo. Such patents are issued in the 
United  States,  Australia,  Belgium,  Canada,  China,  Denmark,  Europe,  France,  Germany,  Hong  Kong,  Ireland,  Israel,  Italy,  Japan,  Netherlands,  New 
Zealand, Spain, Sweden, and United Kingdom, and patent applications are pending in the United States, Australia, Canada, China, Europe, Hong Kong, 
Israel,  Japan,  and  New  Zealand.  These  patents,  and  any  patents  issued  from  pending  patent  applications,  are  expected  to  expire  in  2038,  excluding  any 
potential additional patent term for patent term adjustments or patent term extensions, if applicable. We have requested patent term extension for one patent 
relating to the OCS Heart, U.S. Patent No. 7,651,835, which, if granted, would expire in 2032.

As of December 31, 2023, our patent portfolio relating to the OCS Liver or liver transplantation technology includes a family of issued and pending 
patent applications with claims that are generally directed to certain systems, including perfusion circuits for perfusing a liver ex vivo. Such patents are 
issued in the United States and Australia, and applications are pending in the United States, Australia, Canada, China, Hong Kong, Israel, Japan and New
Zealand. This patent and any patents issued from pending patent applications are expected to expire in 2035, excluding any potential additional patent term 
for patent term adjustments or patent term extensions, if applicable. We have requested patent term extension for one patent relating to the OCS Liver, U.S. 
Patent No. 10,076,112, which, if granted, would expire in 2035. 

As  of  December  31,  2023,  our  patent  portfolio  relating  to  the  OCS  Solutions  or  other  solutions  for  transplantation  systems  includes  families 
comprised of patents and patent applications with claims that are generally directed to compositions of certain perfusion fluids. Such patents are issued in 
the United States, Australia, China, Israel, Japan, New Zealand and patent applications are pending in the United States, Canada, China, Europe, Hong 
Kong, and New Zealand. These patents, and any patents issued from pending patent applications, are expected to expire in 2035, excluding any potential 
additional patent term for patent term adjustments or patent term extensions, if applicable.

The term of individual patents depends on the legal term for patents in the countries in which they are granted. In most countries, including the 
United States, the patent term is generally 20 years from the earliest filing date of a non-provisional patent application in the applicable country. We cannot 
assure that patents will be issued from any of our pending applications or that, if patents are issued, they will be of sufficient scope or strength to provide 
meaningful  protection  for  our  technology.  Notwithstanding  the  scope  of  the  patent  protection  available  to  us,  a  competitor  could  develop  methods  or 
devices that are not covered by our patents. Furthermore, numerous U.S. and foreign issued patents and patent applications owned by third parties exist in 
the fields in which we are developing products. Because patent applications can take many years to issue, there may be applications unknown to us, which 
applications may later result in issued patents that our existing or future products or proprietary technologies may be alleged to infringe.

There has been substantial litigation regarding patent and other intellectual property rights in the medical device industry. In the future, we may need 
to engage in litigation to enforce patents issued or licensed to us, to protect our trade secrets or know-how, to defend against claims of infringement of the 
rights of others or to determine the scope and validity of the proprietary rights of others. Litigation could be costly and could divert our attention from other 
functions and responsibilities. Adverse determinations in litigation could subject us to significant liabilities to third parties, could require us to seek licenses 
from third parties and could prevent us from manufacturing, selling or using the OCS, any of which could severely harm our business.

Competition

Competition in organ preservation for transplantation can be classified into two main segments: (1) cold storage and cold perfusion technologies and 
(2) warm perfusion technologies. In both cold storage and cold perfusion, the organs are not functioning and are metabolically inactive. The characteristics 
of cold storage and cold perfusion described above significantly limit donor organ utilization and are a primary driver of post-transplant complications. 
Supply  of  cold  storage  and  cold  perfusion  products  is  fragmented  with  a  number  of  companies  mainly  providing  undifferentiated  flush  and  perfusion 
solutions or temperature controlled cold storage devices.

Warm  perfusion  preservation  for  solid  organ  transplant  is  an  emerging  alternative  designed  to  address  the  limitations  of  cold  storage  and  cold 
perfusion. In warm perfusion, the organs are functioning and metabolically active. We are aware of only two other companies providing warm perfusion 
systems, OrganOx Limited and XVIVO Perfusion AB, both of which offer single-organ warm perfusion systems for the liver and lung, respectively.

We believe that our principal competitive factors include:

•

•

•

•

•

•

•

•

•

•

strong clinical evidence from large trials demonstrating safety, effectiveness and clinical benefits;

superior technology;

our NOP, including clinical service and logistics services;

regulatory approvals for broad clinical indications of use;

ease of integration into current organ retrieval workflow, including system portability across all modes of transportation;

platform capabilities designed to support multiple organ transplant programs;

brand recognition among leading transplant programs worldwide;

established clinical relationships and a core of committed clinical users;

commercial reimbursement; and

sophisticated clinical training and support program to users worldwide.

Research, Development and Clinical Trial Operations

Our research, development and clinical trial operations function consists of a dedicated clinical trial team that has trial management, data collection 
and biostatistics expertise. Our product engineering function consists of multi-disciplinary engineering teams that have electrical, mechanical, systems and 
software  engineering  expertise.  Our  regulatory  function  includes  a  team  with  both  U.S.  and  international  medical  device  regulatory  expertise  and  is 
supported by senior FDA regulatory advisors and outside legal counsel. For the years ended December 31, 2023, 2022 and 2021 our research, development 
and clinical trials expenses were $36.1 million, $26.8 million and $22.3 million, respectively.

This team is focused on the following research, development and clinical trial activities:

•

•

•

•

developing the next generation OCS; 

developing applications to expand the access and use of the data generated from the OCS;

expanding the body of clinical evidence supporting the use of the OCS platform through pre-market clinical trials, post-market registries and 
scientific publications;

improving incrementally the technology and manufacturing efficiency of our current platform; and

12

 
 
•

conducting research to investigate new clinical applications and uses for the OCS platform.

Manufacturing and Supply Chain Operations

We  design  and  assemble  our  OCS  Consoles  and  disposable  OCS  Perfusion  Sets  at  our  facility  in  Andover,  Massachusetts.  We  have  recently 
increased the size of our manufacturing facility at the Andover site to increase our manufacturing capacity to meet current and future demand. We believe 
this expanded facility’s capacity is sufficient to cover the next several years of forecasted demand. We have added a second shift to our existing cleanroom 
and we have the ability to add additional shifts to the new, expanded, cleanroom to further increase production capacity. We manufacture our sterilized 
disposable OCS Perfusion Sets in a class 10,000 cleanroom. We source many of the components for the OCS Console and OCS Perfusion Sets from third-
party suppliers that are required to manufacture and test them according to our specifications. We purchase some of the components of the OCS Console 
and OCS Perfusion Set from single-source suppliers and, in a few cases, sole-source suppliers. We rely on third parties to sterilize our products prior to 
sale. 

We source the OCS Solutions using our proprietary formulas from third-party suppliers. Fresenius is our single-source supplier of OCS Solutions for 
the  OCS  Lung  and  OCS  Heart.  Our  agreement  with  Fresenius  for  the  supply  of  OCS  Lung  Solution  was  previously  through  April  2024  and  was 
automatically extended for 24 months through April 2026. Upon expiration the agreement will continue to extend for subsequent periods of 24 months 
each, unless terminated by either party at least 12 months prior to the end of the initial term or the then-current extension term. We may also terminate this 
agreement with 12 months’ notice if we request that Fresenius qualifies a second manufacturing plant or qualifies a reputable third party to manufacture the 
OCS Lung Solution and Fresenius fails to respond to this request. Our agreement with Fresenius includes an obligation to meet certain annual minimum 
purchase commitments based upon rolling order forecasts that we provided to Fresenius in accordance with this agreement. Our agreement with Fresenius 
for the supply of OCS Heart Solution has one-year evergreen terms, terminable by either party at least 12 months prior to the end of the then-current term.

Our  supply  chain  and  operations  team  includes  supply  chain  procurement  and  planning,  production  and  test  employees,  sustaining  engineers, 

manufacturing engineers and field service technicians.

Product Regulation 

Our OCS products and our operations are subject to extensive regulation by the FDA and other federal and state authorities in the United States, as 

well as comparable authorities in the European Union and other countries.

Our products are subject to regulation as medical devices under the Federal Food, Drug and Cosmetic Act, or FDCA, as implemented and enforced 
by  the  FDA.  The  FDA  regulates  the  development,  design,  non-clinical  and  clinical  research,  manufacturing,  safety,  effectiveness,  labeling,  packaging, 
storage,  installation,  servicing,  recordkeeping,  premarket  clearance  or  approval,  adverse  event  reporting,  advertising,  promotion,  marketing  and 
distribution, and import and export of medical devices to ensure that medical devices distributed domestically are safe and effective for their intended uses 
and otherwise meet the requirements of the FDCA. 

In addition to U.S. regulations, we are subject to a variety of regulations in the European Union and other countries, governing medical devices, 
clinical investigations and commercial sales and distribution of our products. Regardless of whether we have or are required to obtain FDA clearance or 
approval for a product, we will be required to obtain the relevant authorizations/approvals before commencing clinical trials/investigations and to obtain the 
necessary authorizations, approvals or certifications of our products under the comparable regulatory authorities of countries outside of the United States 
before  we  can  commence  clinical  trials/investigations  or  commercialize  our  products  in  those  countries.  In  the  European  Union,  the  manufacturer  of  a 
device  must  affix  a  Conformité  Européene  mark,  or  CE  Mark,  which  allows  the  device  to  be  placed  on  the  market  anywhere  in  the  EU  and  additional 
Member States of the European Economic Area, or EEA, (i.e., Norway, Lichtenstein and Iceland). The EU CE mark is also recognized in Turkey and, for a 
transitional period following the UK’s withdrawal from the European Union, referred to as Brexit, in the United Kingdom.

The  authorization/approval  processes  for  devices  outside  the  European  Union  will  vary  from  country  to  country  and  the  time  may  be  longer  or 

shorter than that required for FDA clearance or approval or EU CE marking.

13

 
FDA Premarket Clearance and Approval Requirements

Unless  an  exemption  applies,  each  medical  device  commercially  distributed  in  the  United  States  requires  either  FDA  clearance  of  a  510(k) 
premarket notification, approval of a PMA or issuance of a de novo classification order. Under the FDCA, medical devices are classified into one of three 
classes—Class I, Class II or Class III—depending on the degree of risk associated with each medical device and the extent and regulatory controls needed 
to  ensure  its  safety  and  effectiveness.  Class  I  includes  devices  with  the  lowest  risk  to  the  patient  and/or  the  user  and  are  those  for  which  safety  and 
effectiveness  can  be  reasonably  assured  by  adherence  to  the  FDA’s  general  controls  for  medical  devices,  which  include  compliance  with  the  applicable 
portions of the Quality System Regulation, or QSR, facility registration and product listing, reporting of adverse medical events and device malfunctions,
and truthful and non-misleading labeling, advertising, and promotional materials. Class II devices are subject to the FDA’s General Controls and special 
controls as deemed necessary by the FDA to ensure the safety and effectiveness of the device. These special controls can include performance standards, 
post-market surveillance, patient registries and FDA guidance documents. While most Class I devices are exempt from the 510(k) premarket notification 
requirement,  manufacturers  of  most  Class  II  devices  are  required  to  submit  to  the  FDA  a  premarket  notification  under  Section  510(k)  of  the  FDCA 
requesting a substantial equivalence determination that provides permission to commercially distribute the device. The FDA’s permission to commercially 
distribute  a  device  subject  to  a  510(k)  premarket  notification  is  generally  known  as  510(k)  clearance.  Under  the  510(k)  process,  the  manufacturer  must 
submit to the FDA a premarket notification demonstrating that the device is “substantially equivalent” to either a device that was legally marketed prior to 
May 28, 1976, the date upon which the Medical Device Amendments of 1976 were enacted, or a device that was reclassified from Class III to Class II or I, 
or  another  commercially  available  device  that  was  cleared  through  the  510(k)  process  or  that  was  granted  marketing  authorization  through  the  de  novo 
classification process under section 513(f)(2) of the FDCA, or a 510(k) exempt device. We received 510(k) clearance for the OCS Lung Solution for cold 
flush, storage and transportation of donor lungs in July 2021, for the OCS Lung Donor Flush Set in November 2022, and for the OCS Heart Leukocyte 
Reducing Filter in October 2023. 

Devices deemed by the FDA to pose the greatest risks, such as life-sustaining, life-supporting and many implantable devices, or devices that have 

been found not substantially equivalent to a legally marketed Class I or Class II predicate device, are placed in Class III, requiring approval of a PMA. 

Each of our OCS warm perfusion products is a Class III device. We have received a PMA for each of the following:

•

•

•

•

•

OCS Lung for the preservation of standard criteria donor lungs for double-lung transplantation;

OCS Lung for the preservation of donor lungs initially deemed unsuitable due to limitations of cold storage for double-lung transplantation; 

OCS Heart for the preservation of DBD donor hearts deemed unsuitable due to limitations of cold storage (e.g. >4 hours of cross-clamp time);

OCS Heart for the ex vivo reanimation, functional monitoring, and beating-heart preservation of donation-after-circulatory-death (DCD) hearts; 
and

OCS Liver for the preservation of DBD and DCD donor livers < 55 years old, macrosteatosis < 15% and with < 30 minutes of warm ischemia 
time.

PMA Pathway

Class  III  devices  require  an  approved  PMA  before  they  can  be  marketed.  The  PMA  process  is  more  demanding  than  the  510(k)  premarket 
notification process. In a PMA, the manufacturer must demonstrate that the device is safe and effective, and the PMA must be supported by extensive data, 
including data from preclinical studies and human clinical trials. The PMA must also contain a full description of the device and its components, a full 
description of the methods, facilities and controls used for manufacturing, and proposed labeling. If the FDA accepts the application for review, it has 180 
days under the FDCA to complete its review of a PMA, although in practice, the FDA’s review generally takes one year, or even longer, from the time the 
PMA  application  is  submitted  to  the  FDA  until  an  approval  is  obtained.  An  advisory  committee  of  experts  from  outside  the  FDA  may  be  convened  to 
review and evaluate the application and provide recommendations to the FDA as to the approvability of the device. The FDA may or may not accept the 
panel’s  recommendation.  In  addition,  the  FDA  will  generally  conduct  a  preapproval  inspection  of  the  applicant  or  its  third-party  manufacturers’ 
manufacturing  facility  or  facilities  to  ensure  compliance  with  the  QSR  and,  in  some  cases,  will  audit  the  applicant  and  clinical  sites  as  part  of  its 
Bioresearch Monitoring program. 

14

 
During  the  PMA  review,  the  FDA  assesses  whether  the  data  and  information  in  the  PMA  constitute  valid  scientific  evidence  to  support  a 
determination that there is a reasonable assurance that the device is safe and effective for its intended use(s) based on the proposed labeling. The FDA may 
approve a PMA with post-approval conditions intended to ensure the safety and effectiveness of the device, including, among other things, restrictions on 
labeling,  promotion,  sale  and  distribution,  and  collection  of  long-term  follow-up  data  from  patients  in  the  clinical  study  that  supported  a  PMA  or 
requirements  to  conduct  additional  clinical  studies  post-approval.  The  FDA  may  condition  a  PMA  approval  on  some  form  of  post-market  surveillance 
when  deemed  necessary  to  protect  the  public  health  or  to  provide  additional  safety  and  effectiveness  data  for  the  device  in  a  larger  population  or  for  a 
longer  period  of  use.  Failure  to  comply  with  the  conditions  of  approval  can  result  in  material  adverse  enforcement  action,  including  withdrawal  of  the 
approval. Certain changes to an approved device, such as changes in manufacturing facilities, methods, or quality control procedures, or changes in the 
design or performance specifications, which affect the safety or effectiveness of the device, require submission and approval of a PMA supplement. PMA 
supplements often require submission of the same type of information as a PMA, except that the supplement is limited to information needed to support 
any  changes  from  the  device  covered  by  the  original  PMA  and  may  not  require  as  extensive  clinical  data  or  the  convening  of  an  advisory  committee. 
Certain  other  changes  to  an  approved  device  require  the  submission  and  approval  of  a  new  PMA,  such  as  when  the  design  change  causes  a  different 
intended use, mode of operation, and technical basis of operation, or when the design change is so significant that a new generation of the device will be 
developed, and the data that were submitted with the original PMA are not applicable for the change in demonstrating a reasonable assurance of safety and 
effectiveness.

Clinical Trials

Clinical  trials  are  almost  always  required  to  support  a  PMA  application  and  may  be  necessary  to  support  PMA  supplements  for  additional 
indications or modified versions of a marketed device product. All clinical investigations of investigational devices to determine safety and effectiveness 
must be conducted in accordance with the FDA’s investigational device exemption, or IDE, regulations that govern investigational device labeling, prohibit 
promotion  of  the  investigational  device,  and  specify  an  array  of  study  review  and  approval,  informed  consent,  recordkeeping,  reporting  and  monitoring 
responsibilities  of  study  sponsors  and  study  investigators.  If  the  device  presents  a  “significant  risk”  to  human  health,  as  defined  by  the  FDA,  the  FDA 
requires  the  device  sponsor  to  submit  an  IDE  application  to  the  FDA,  which  must  become  effective  prior  to  commencing  human  clinical  trials.  To  be 
approved, an IDE application must be supported by appropriate data, such as animal and laboratory test results, showing that it is safe to test the device in 
humans and that the testing protocol is scientifically sound. If the FDA determines that there are deficiencies or other concerns with an IDE for which it 
requires modification, the FDA may permit a clinical trial to proceed under a conditional approval. Acceptance of an IDE application for review does not 
guarantee that the FDA will allow the IDE to become effective and, if it does become effective, the FDA may or may not determine that the data derived 
from the trials support the safety and effectiveness of the device to support marketing approval or clearance, or to warrant the continuation of clinical trials. 
An IDE supplement must be submitted to, and approved by, the FDA before a sponsor or investigator may make a change to the investigational plan that 
may  affect  its  scientific  soundness,  study  plan  or  the  rights,  safety  or  welfare  of  human  subjects.  Non-significant  risk  device  studies  do  not  require 
submission of an IDE application to FDA.

In  the  United  States,  the  study  must  be  approved  by,  and  conducted  under  the  oversight  of,  an  Institutional  Review  Board,  or  IRB.  The  IRB  is 

responsible for the initial and continuing review of the study and may pose additional requirements for the conduct of the study. 

During a study, the sponsor is required to comply with the applicable FDA requirements, including, for example, trial monitoring, selecting clinical 
investigators  and  providing  them  with  the  investigational  plan,  ensuring  IRB  review,  adverse  event  reporting,  record  keeping  and  prohibitions  on  the 
promotion of investigational devices or on making safety or effectiveness claims for them. After a trial begins, we, the FDA or the IRB could suspend or 
terminate a clinical trial at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits or protocol 
violations. 

Post-market Regulation

After a device is cleared or approved for marketing, numerous and pervasive regulatory requirements continue to apply. These include:

•

•

establishment registration and device listing with the FDA;

QSR  requirements,  which  require  manufacturers,  including  third-party  manufacturers,  to  follow  stringent  design,  testing,  control,
documentation and other quality assurance procedures during all aspects of the design and manufacturing process;

Our  manufacturing  processes  are  required  to  comply  with  the  applicable  portions  of  the  QSR,  which  cover  the  methods  and  the  facilities  and 
controls for the design, manufacture, testing, production, processes, controls, quality assurance, labeling, packaging, distribution, installation and servicing 
of finished devices intended for human use. The QSR also requires, among other things, maintenance of a device master record, device history file, and 
complaint files. As a manufacturer, our facilities, records and manufacturing processes are subject to periodic scheduled or unscheduled inspections by the 
FDA. Our failure to maintain compliance with the QSR or other applicable regulatory requirements could result in the shutdown of, or restrictions on, our 
manufacturing operations and the recall or seizure of our products. The discovery of previously unknown problems with any of our products, including 
unanticipated  adverse  events  or  adverse  events  of  increasing  severity  or  frequency,  whether  resulting  from  the  use  of  the  device  within  the  scope  of  its 
clearance or off-label by a physician in the practice of medicine, could result in restrictions on the device, including the removal of the product from the 
market or voluntary or mandatory device recalls.

The  FDA  has  broad  regulatory  compliance  and  enforcement  powers.  If  the  FDA  determines  that  we  failed  to  comply  with  applicable  regulatory 

requirements, it can take a variety of compliance or enforcement actions, which may result in any of the following sanctions:

•

•

•

•

•

Regulation of Medical Devices in the European Union

In  the  European  Union,  our  products  are  regulated  as  medical  devices.  Regulation  of  our  medical  devices  in  the  European  Union  is  harmonized 
through Regulation (EU) 2017/745, or the MDR, which repealed and replaced the Medical Devices Directive (93/42/EEC) with effect from May 26, 2021. 

However, the competent authorities in each member state enforce the standards set out in the MDR against relevant economic operators (including 
the manufacturer, importer, authorized representative and distributors) making medical devices available in the member state (although, under the MDR 
there are provisions for national competent authorities to inform other competent authorities, the European Commission and Notified Bodies, as applicable, 
of certain non-compliances).

Under  the  MDR,  a  medical  device  placed  on  the  market  in  the  European  Union  must  meet  the  applicable  General  Safety  and  Performance 
Requirements, or GSPRs, laid down in Annex I of the MDR. Similar to the U.S. system, medical devices are classified into one of four classes based on 
risk: I, IIa, IIb and III, with class I representing the lowest risk products and class III the highest risk products. One of the most fundamental GSPRs is that 
a medical device must be designed and manufactured in such a way that it will not compromise the clinical condition or safety of patients, or the safety and 
health of users and others (provided that any risks posed are acceptable when weighted against the benefits). In addition, the GSPRs include (but are not 
limited to) that the device must achieve the performances intended by the manufacturer, be designed, manufactured and packaged in a suitable manner and 
the manufacturer must establish, implement, document and maintain a risk management plan. The European Commission has adopted various standards 
applicable to medical devices, referred to as harmonized standards. While not mandatory, compliance with these harmonized standards is often viewed as 
the  easiest  way  to  satisfy  the  GSPRs  as  a  practical  matter.  Compliance  with  a  harmonized  standard  developed  to  implement  a  GSPR  also  creates  a
rebuttable presumption that the device satisfies that essential requirement. Currently the European Commission has only harmonized a relatively limited 
number of standards (these include, for example, standards of sterilization, biological evaluation, the quality management system, etc.) but the Commission 
will continue to harmonize more standards.

To  demonstrate  compliance  with  the  GSPRs,  medical  device  manufacturers  must  undergo  a  conformity  assessment  procedure,  which  varies 
according  to  the  type  of  medical  device  and  its  classification.  Conformity  assessment  procedures  require  an  assessment  of  available  clinical  evidence, 
literature data for the product and post-market experience in respect of similar products already marketed.

For  all  devices  other  than  low  risk  devices  (i.e.,  Class  I  non-sterile,  non-measuring  devices),  a  conformity  assessment  procedure  requires  the 
intervention of a notified body. The notified body must audit and examine a product’s technical dossier and the manufacturer's quality system. If satisfied 
that the relevant product conforms to the relevant GSPRs, the notified body issues a certificate of conformity, which the manufacturer uses as a basis for its 
own declaration of conformity. The manufacturer may then affix the CE Mark to the device, which allows the device to be placed on the market throughout 
the  European  Union  (and  by  extension  the  European  Economic  Area).  Once  the  product  has  been  placed  on  the  market  in  the  European  Union,  the 
manufacturer must comply with requirements for reporting incidents and field safety corrective actions associated with the medical device. The notified 
body has ongoing audit rights and must be notified of all significant changes to the device.

Although the MDR now applies so all new devices placed on the market must be CE marked under it, under the transition period granted by the 
MDR,  certificates  issued  by  notified  bodies  for  medical  devices  under  the  Medical  Devices  Directive  before  May  26,  2021  may  remain  valid  and  the 
devices may continue to be placed on the EU market potentially until the end of December 2027 or 2028 (depending on the class of device) and provided 
the manufacturer satisfies certain requirements, including that there are no significant changes in the design and intended purpose of these devices.

The requirements of the MDR are significantly more onerous than under the EU Medical Devices Directive. The increased regulation includes the 

following:

•

•

•

strengthening of the rules on placing devices on the market, by requiring more evidence substantiating safety and efficacy of the device and 
more detailed content in the technical documentation for each device;

requiring a structured post-market clinical follow-up program for every medical device;

necessitating more thorough post-market surveillance program, with an emphasis on active gathering and analyzing the data;

17

 
•

•

•

•

establishing explicit provisions on manufacturers’ responsibilities for the follow-up of the quality, performance and safety of devices placed 
on the market and new responsibilities for distributors and importers;

improving the traceability of medical devices throughout the supply chain to the end-user or patient through a unique identification number;

setting up a central database into which manufacturers and other economic operators are required to input data with the goal of providing EU 
competent  authorities  as  well  as  provide  patients,  healthcare  professionals  and  the  public  with  comprehensive  information  on  products 
available in the European Union; and

strengthening  rules  for  the  assessment  of  certain  high-risk  devices,  such  as  implants,  which  may  have  to  undergo  an  additional  check  by 
experts before they are placed on the market.

All  of  our  products  that  were  previously  certified  under  the  EU  Medical  Devices  Directive,  including  OCS  Heart,  OCS  Lung,  and  OCS  Liver 
systems, which includes the OCS Console, the OCS disposables, and the OCS solution additives, have now been recertified under the MDR. We received 
the CE Mark for the OCS Liver combined with our solution additives under the MDR in May 2023, with an effective date of April 2023.

Clinical Investigations

Clinical evidence is required for most medium and high risk devices. In some cases, a clinical study may be required to support the CE marking of a 
device. A manufacturer that wishes to conduct a clinical study involving the device is subject to the clinical investigation requirements of the MDR, EU 
member  state  requirements,  and  current  good  clinical  practices  defined  in  harmonized  standards  and  guidance  documents.  Clinical  investigations  for 
medical  devices  cannot  proceed  without  a  positive  opinion  of  an  ethics  committee  and  approval  by  or  notification  to  the  relevant  national  regulatory 
authorities. Both regulators and ethics committees also require the submission of serious adverse event reports during a study and may request a copy of the 
final study report.

Post-marketing Requirements

In the European Union, we are currently required to comply with strict post-marketing obligations that apply after a device is placed on the market. 
These include the obligation to have in place a post-market surveillance system and vigilance system. These requirements include that the manufacturer 
must  report  to  the  relevant  national  competent  authorities  any  serious  incident  involving  devices  made  available  on  the  market  and  any  field  safety 
corrective action in respect of devices made available on the market or undertaken in a third country in relation to a device made available on the market. 
Additionally, the manufacturer of high risk devices must submit periodic safety update reports to its notified body and manufacturers of lower risk devices 
must maintain periodic safety update reports as part of the technical documentation for their products. 

Authorities in the European Union also closely monitor the marketing programs implemented by device companies. The MDR prohibits making 
misleading claims, including promoting the product for or suggesting a use that is not part of its intended purpose. However, the obligations that companies 
must  fulfill  concerning  premarketing  approval  of  promotional  material  vary  among  member  states  of  the  European  Union  as  beyond  that  requirement, 
advertising and promotion law for medical devices is not harmonized in the European Union.

Regulations Applicable to Transport of Organs Intended for Transplantation

In  the  European  Union,  Directive  2010/53/EU  sets  out  certain  standards  which  the  EU  member  states  should  apply  in  respect  of  procurement, 
preservation  and  transport  of  organs  intended  for  transplantation.  While  we  are  not  directly  affected  by  this  directive,  our  EU  customers  are,  and  our 
products may either help or impede their compliance with this Directive.

Regulation of Medical Devices in the United Kingdom 

The  Medicines  and  Healthcare  products  Regulatory  Agency,  or  the  MHRA,  is  responsible  for  regulating  the  UK  medical  devices  market.  The 
MHRA performs market surveillance of medical devices on the UK market and is able to take decisions over the marketing and supply of devices in the 
UK. The MHRA is also responsible for the designation and monitoring of UK approved bodies (the equivalent of EU notified bodies). 

18

 
Since May 26, 2021, the EU Medical Devices Regulation (Regulation 2017/745), or the EU MDR, has applied in EU Member States and Northern 
Ireland.  Further,  the  In  Vitro  Diagnostic  Medical  Devices  Regulation  (Regulation  2017/746),  or  the  EU  IVDR,  has  applied  in  EU  Member  States  and 
Northern  Ireland  since  May  26,  2022.  As  these  EU  regulations  took  effect  after  the  UK  left  the  European  Union,  they  were  not  EU  law  automatically 
retained by the EU (Withdrawal) Act 2018 and therefore do not and will not apply in Great Britain (England, Wales and Scotland). 

In the United Kingdom medical devices are regulated under the Medical Devices Regulations 2002 (SI 2002 No 618, as amended) (UK MDR 2002) 
which give effect in UK law to the directives listed below (which have now been repealed and replaced in the European Union by the EU MDR and EU 
IVDR):

•

•

•

Directive 90/385/EEC on active implantable medical devices (EU AIMDD)

Directive 93/42/EEC on medical devices (EU MDD)

Directive 98/79/EC on in vitro diagnostic medical devices (EU IVDD)

This means that the Great Britain route to market is based on the requirements derived from the above EU legislation and is thus different to the 
route  to  market  for  the  European  Union.  However,  although  neither  the  EU  MDR  nor  EU  IVDR  apply  in  Great  Britain,  the  UK  MDR  2002  provide  a 
transitional period that allows manufacturers to place devices CE marked under the EU MDR or EU IVDR (including their relevant transition periods), on 
the market in Great Britain potentially up until June,30 2030.

Since January 1, 2021 (when the Brexit transition period ended), there have been a number of changes, introduced through secondary legislation, on 

how medical devices are placed on the market in Great Britain (England, Wales and Scotland). These include:

•

•

•

•

•

a  new  route  to  market  and  product  marking  (the  UKCA  marking)  is  available  for  manufacturers  wishing  to  place  medical  devices  on  the 
Great Britain market;

all medical devices, including in vitro diagnostic medical devices, or IVDs, custom-made devices and systems or procedure packs, need to be 
registered with the MHRA before they are placed on the Great Britain market;

medical device manufacturers based outside the UK who wish to place a device on the Great Britain market need to appoint a single UK 
Responsible Person for all devices who will act on their behalf to carry out specified tasks, such as registration;

the EU no longer recognizes UK Notified Bodies and UK Notified Bodies are not able to issue CE certificates. (Following Brexit, certificates 
issued by our UK notified body (BSI UK) were no longer recognized for CE marking purposes. BSI Netherlands thus reissued the certificates 
that allow CE marking of the OCS products); and

UK Notified Bodies have become UK Approved Bodies. UK Approved Bodies can issue UKCA marking certificates. 

We have appointed a UK Responsible Person for our devices in the UK. 

Clinical Investigations

In order to demonstrate compliance with the essential requirements of the UK MDR 2002 and the general safety and performance requirements of 
the EU MDR, and in order to justify the application of UKCA/CE/CE UKNI marking, it will sometimes be necessary for the manufacturer of the device to 
provide clinical data with which to back up claims made for that device. This may involve the need for a specifically designed clinical investigation to: 

•

•

verify that under normal conditions of use the performance characteristics of the device are those intended by the manufacturer; and 

determine any undesirable side-effects and to assess whether these are acceptable risks when weighed against the intended performance of 
the device. 

19

 
If  such  an  investigation  is  necessary,  and  will  be  conducted  in  the  UK,  the  manufacturer  must  make  an  application  to  the  MHRA  before  the 
investigation is due to begin, and such a clinical investigation may only proceed provided no grounds for objection are raised by the MHRA within the 
statutory review time constraint. The MHRA will reach a decision aided by a number of expert assessors. It is the responsibility of the manufacturer both to 
notify the MHRA and to submit the documentation required by the UK MDR 2002 to the MHRA. The clinical investigator will normally have no direct 
contact with the MHRA. The manufacturer must also obtain ethics committee approval for the investigation.

Post-marketing Requirements 

Once  a  medical  device  has  been  placed  on  the  UK  market,  the  manufacturer  is  required  to  submit  vigilance  reports  to  the  MHRA  when  certain 
incidents occur in the UK that involve their device. They must also take appropriate safety action when required. The manufacturer must also ensure their 
device meets appropriate standards of safety and performance for as long as it is in use. The advertising and marketing of medical devices is governed in 
the UK by both legislation and self-regulatory codes of practice.

The MHRA Enforcement of Medical Device Regulations in the UK

To ensure that medical devices placed on the market and put into service in the UK meet applicable regulatory requirements the MHRA perform the 

following activities:

•

•

•

assess all allegations of non-compliance brought to them, using a risk-based system;

monitor the activity of UK Approved Bodies designated by MHRA to assess the compliance of manufacturers; and

investigate medical devices as a result of adverse incident reports or intelligence indicating a potential problem.

If MHRA considers that a person or company has committed a serious offense by failing to comply with applicable regulations or the conditions of a 

notice issued then a person/company may be subject to prosecution. 

UK Regulations Applicable to Organs Intended for Transplantation

The  standards  for  the  quality  and  safety  of  organs  for  transplantation  has  been  enacted  into  UK  law  through  The  Quality  and  Safety  of  Organs 
Intended for Transplantation Regulations 2012, as amended. This Regulation allows for the establishment of a Competent Authority for the regulation of 
organ  transplantation.  In  the  UK  the  Competent  Authority  is  the  Human  Tissue  Authority,  which  has  published  the  “The  Quality  and  Safety  of  Organs 
Intended for Transplantation: a documentary framework” which details mandatory requirements as well as guidance on how those requirements may be 
met.  While  we  are  not  directly  affected  by  this  Regulation  and  guidelines,  our  UK  customers  are,  and  our  products  may  either  help  or  impede  their 
compliance with this Regulation. 

Regulation in Other Countries

We are subject to regulations and product registration requirements in many foreign countries in which we may sell our products, including in the 

areas of:

•

•

•

•

•

•

•

design, development, manufacturing and testing (including with respect to significant changes to the products);

product standards;

product safety;

product safety reporting;

marketing, sales and distribution;

packaging and storage requirements;

labeling requirements;

20

 
•

•

•

•

•

•

•

•

•

•

content and language of instructions for use;

clinical trials;

record keeping procedures;

advertising and promotion;

recalls and field corrective actions;

post-market surveillance, including reporting of deaths or serious injuries and malfunctions that, if they were to recur, could lead to death or 
serious injury;

import and export restrictions;

tariff regulations, duties and tax requirements;

registration for reimbursement, agreement of prices with government; and

necessity of testing performed in country by distributors for licensees.

The time required to obtain clearance by foreign countries may be longer or shorter than that for FDA clearance, and requirements for licensing a 
product in a foreign country may differ significantly from FDA requirements. We received a Class II Medical Device License from Health Canada for our 
OCS Liver combined with our solution additives in October 2023 to complement our existing Health Canada licenses for OCS Heart and OCS Lung. 

Adverse events and potential adverse events are monitored closely by regulatory authorities. For example, if, as a result of manufacturing error, the 
efficacy of our products does not meet the standards claimed in the accompanying instructions for use, regulatory authorities could prevent our products 
from being placed on the market.

Internationally, the approaches to product defects will vary. A product may be recalled in one country but not in others. 

Federal, State and Foreign Fraud and Abuse and Physician Payment Transparency Laws

In addition to FDA restrictions on marketing and promotion of drugs and devices, other federal, state, international laws, as well as laws with extra-
territorial effect and market practices restrict our business practices. These laws include, without limitation, U.S. and foreign laws intended to prohibit or 
otherwise regulate activities that might result in fraud, abuse and bribery.

U.S. Laws

U.S. federal healthcare fraud and abuse laws generally apply to our activities because our products are covered under federal healthcare programs 
such  as  Medicare  and  Medicaid.  The  principal  U.S.  federal  healthcare  fraud  and  abuse  laws  applicable  to  us  and  our  activities  include:  (1)  the  Anti-
Kickback  Statute,  which  prohibits  the  knowing  and  willful  offer,  solicitation,  payment  or  receipt  of  anything  of  value  in  order  to  generate  business 
reimbursable by a federal healthcare program; (2) the False Claims Act, which prohibits the submission of false or otherwise improper claims for payment 
to a federally-funded healthcare program, including claims resulting from a violation of the Anti-Kickback Statute; and (3) healthcare fraud statutes that 
prohibit  false  statements  and  improper  claims  to  any  third-party  payor.  There  are  also  similar  state  anti-kickback  and  false  claims  laws  that  apply  to 
activities involving state-funded Medicaid and other healthcare programs as well as to private third-party payers.

21

 
The Anti-Kickback Statute is particularly relevant because of its broad applicability. Specifically, the Anti-Kickback Statute prohibits persons from 
knowingly and willfully soliciting, offering, receiving, or providing remuneration, directly or indirectly, in exchange for, or to induce, either the referral of 
an  individual,  or  the  furnishing,  arranging  for  or  recommending  a  good  or  service  for  which  payment  may  be  made  in  whole  or  part  under  federal 
healthcare programs, such as the Medicare and Medicaid programs. Almost any financial interaction with a healthcare provider, patient or customer will 
implicate the Anti-Kickback Statute. Statutory exceptions and regulatory safe harbors protect certain interactions if specific requirements are met. Only 
those interactions that represent fair market value exchanges, however, are generally protected by an exception or safe harbor. The government can exercise 
enforcement discretion in taking action against unprotected activities. Many interactions in which we commonly engage, such as the provision of business 
courtesies to healthcare practitioners, could implicate the Anti-Kickback Statute and may not be protected by an exception or safe harbor. If the government 
determines that these activities are abusive, we could be subject to enforcement action. Penalties for Anti-Kickback Statute violations may include both 
criminal penalties such as imprisonment and civil sanctions such as fines and possible exclusion from Medicare, Medicaid, and other federal healthcare 
programs. Exclusion would mean that our products were no longer eligible for reimbursement under federal healthcare programs.

Laws and regulations have also been enacted by the federal government and various states to regulate the sales and marketing practices of medical 
device and pharmaceutical manufacturers. The laws and regulations generally limit financial interactions between manufacturers and healthcare providers; 
require  pharmaceutical  and  medical  device  companies  to  comply  with  voluntary  compliance  standards  issued  by  industry  associations  and  the  relevant 
compliance guidance promulgated by the U.S. federal government; and/or require disclosure to the government and/or public of financial interactions, so-
called “sunshine laws”.

The healthcare laws and regulations applicable to us, including those described above, contain ambiguous requirements and are subject to evolving 
interpretations  and  enforcement  discretion.  Manufacturers  must  adopt  reasonable  interpretations  of  requirements  if  there  is  ambiguity  and  those
interpretations could be challenged. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we 
and our officers and employees could be subject to severe criminal and civil financial penalties, including, for example, exclusion from participation as a 
supplier  of  product  to  beneficiaries  covered  by  Medicare  or  Medicaid.  Any  failure  to  comply  with  laws  and  regulations  relating  to  reimbursement  and 
healthcare goods and services could adversely affect our reputation, business, financial condition and cash flows.

International Laws

Many foreign countries have similar laws relating to healthcare fraud and abuse. Foreign laws and regulations may vary greatly from country to 
country. For example, the advertising and promotion of our products is subject to EU Directives concerning misleading and comparative advertising and 
unfair  commercial  practices,  as  well  as  other  EU  member  state  legislation  governing  the  advertising  and  promotion  of  medical  devices.  Sometimes  the 
relevant rules are found in industry guidance rather than legislation—for example, relationships with healthcare professionals in the UK are governed by 
the code of Association of British HealthTech Industries, or ABHI, and rules may limit or restrict the advertising and promotion of our products to the 
general public and impose limitations on our promotional activities with healthcare professionals.

In  the  European  Union  the  consequences  for  failing  to  comply  with  advertising  and  promotional  laws  might  lead  to  reputational  damage,  fines, 

exclusions from public tenders and actions for damages from competitors for unfair competition.

Laws with Extra-territorial Effect

Many countries in which we operate have laws with extra-territorial effect—those laws apply to our operations outside the relevant country, to the 
extent they are breached. Examples of such laws include the Foreign Corrupt Practices Act, or the FCPA, the UK Bribery Act 2010 and the General Data 
Protection Regulation, or the GDPR.

The extra-territorial effect of those laws affects our sales and marketing strategy, since in many countries healthcare professionals are officers of the 
state. This is particularly important in the context of bribery offenses, which in the UK and in the United States include the offense of bribing a foreign 
public official.

Data Privacy and Security Laws

We are, and in the future may become, subject to various U.S. federal and state as well as foreign laws that protect the confidentiality of certain 

patient health information, including patient medical records, and restrict the use and disclosure of patient health information by healthcare providers.

22

 
The Health Insurance Portability and Accountability Act of 1996, or HIPAA, governs the conduct of certain electronic healthcare transactions and 
requires certain entities, called covered entities, to handle and protect, among other things, the privacy and security of protected health information, or PHI, 
in  certain  ways.  HIPAA  also  requires  business  associates  to  enter  into  business  associate  agreements  with  covered  entities  and  to  safeguard  a  covered 
entity’s PHI against improper use and disclosure.

HIPAA  privacy  regulations  cover  the  use  and  disclosure  of  PHI  by  covered  entities  as  well  as  business  associates,  which  are  defined  to  include 
subcontractors  that  create,  receive,  maintain,  or  transmit  PHI  on  behalf  of  a  business  associate.  These  regulations  also  set  forth  certain  rights  that  an 
individual may have with respect to his or her PHI maintained by a covered entity, including the right to access or amend certain records containing PHI, or 
to request restrictions on the use or disclosure of PHI. HIPAA security regulations set forth requirements for safeguarding the confidentiality, integrity, and 
availability of protected health information that is electronically transmitted or electronically stored. The Health Information Technology for Economic and 
Clinical Health Act, among other things, provides certain health information security breach notification requirements. Under these laws, the covered entity 
must  notify  any  individual  whose  PHI  is  breached  as  required  under  the  breach  notification  rule.  Although  we  believe  that  we  currently  are  neither  a 
“covered entity” nor a “business associate” directly under HIPAA, a business associate relationship may be imputed from facts and circumstances even in 
the absence of an actual business associate agreement. In addition, HIPAA may affect our interactions with customers who are covered entities or their 
business associates.

The HIPAA privacy and security regulations establish a uniform federal “floor” and do not supersede state laws that are more stringent or provide 
individuals with greater rights with respect to the privacy or security of, and access to, their health and other personal information. States are increasingly 
regulating  the  privacy  and  security  of  individually  identifiable  information,  including  financial  information  and  health  information.  For  example,  the 
California Consumer Privacy Act, or CCPA, gives California residents certain rights, including the right to ask covered companies to disclose the types of 
personal information collected and delete a consumer’s personal information, and imposes several obligations on covered companies to provide notice to 
California  consumers  regarding  their  data  processing  activities  and  limitations  on  covered  companies’  ability  to  sell  personal  information.  These 
protections have been expanded by California Privacy Rights Act of 2020, or CPRA, along with new privacy laws in Virginia, Colorado and several other 
states. We expect additional federal and state legislative and regulatory efforts to regulate consumer privacy in the future. Some states have also passed 
further protections focused on data protection for health information, including the Washington My Health My Data Act.

In the EEA, as well as in the United Kingdom, or the UK, -post-Brexit, we may be subject to laws relating to our collection, control, processing and 
other use of personal data, such as data relating to an identified or identifiable living individual. Following Brexit, the UK has substantively retained the 
same privacy rules as it had when a member of the European Union. We process personal data in relation to our operations. We process data of both our 
employees and our customers, including health and medical information. The data privacy regime in the EEA includes the GDPR, regarding the processing 
of personal data and the free movement of such data, which became applicable on May 25, 2018, the E-Privacy Directive 2002/58/EC and national laws 
implementing or supplementing each of them. Each EU member state has transposed the requirements laid down by the E-Privacy Directive into its own 
national data privacy regime and therefore the laws may differ by jurisdiction, sometimes significantly. The GDPR was retained post-Brexit in the UK as 
the UK GDPR. In addition, many EEA member states have passed legislation addressing areas where the GDPR permits member states to derogate from 
the  regulation’s  requirements,  thus  leading  to  divergent  requirements  between  member  states  in  spite  of  the  GDPR’s  stated  goal  of  creating  a  uniform 
privacy law for the entire EEA. The UK has done the same. We need to ensure compliance with the rules in each jurisdiction where we are established. 
Even if not established in the EEA (or the UK), we may otherwise be subject to local privacy laws in those regions. For example, we may be subject to the 
GDPR  (or  UK  GDPR)  even  when  processing  personal  data  in  connection  with  offering  goods  or  services  to  persons  located  in  the  EEA  (or  UK)  or 
monitoring the behavior of persons located in the EEA (or UK).

GDPR requirements include that personal data may only be collected for specified, explicit and legitimate purposes based on a certain legal bases 
set forth in GDPR, and may only be processed in a manner consistent with those purposes. Processing of personal data also needs to be adequate, relevant, 
not excessive in relation to the purposes for which it is collected and secure. Personal data must not be kept for longer than necessary for the purposes of 
collection.  To  the  extent  that  we  process,  control  or  otherwise  use  sensitive  data  relating  to  living  individuals  (for  example,  patients’  health  or  medical 
information, or genetic data or biometric data used for identification purposes, and other types of "special category data" listed in GDPR), more stringent 
rules may apply, limiting the circumstances and the manner in which we are legally permitted to process that data and transfer that data outside of the EEA 
(UK). In particular, in order to process such data, explicit consent to the processing (including any cross-border transfer) may be required from the data 
subject (being the person to whom the personal data relates), though in certain cases, and depending on the jurisdiction in which the data originate or are 
processed, such data may be processed absent explicit consent for purposes of medical diagnosis, public interest in the area of public health (including the 
safety and efficacy of medical devices) or scientific research. The same rules apply to us in the UK under the UK GDPR.

23

 
The GDPR and UK GDPR also impose potentially onerous accountability obligations requiring data controllers and processors to maintain a record 
of their data processing and privacy policies/notices. They require data controllers to be transparent and disclose to data subjects in privacy notices (in a 
concise, intelligible and easily accessible form but at the same time at a sufficiently granular level) how their personal information is to be used, impose 
limitations  on  retention  of  information,  encourage  the  use  of  pseudonymization  techniques  (i.e.,  key-coded)  data,  introduces  mandatory  data  breach 
notification  requirements  and  sets  higher  standards  for  data  controllers  to  demonstrate  that  they  have  obtained  valid  consent  for  certain  data  processing 
activities. Fines for non-compliance with the GDPR and the UK GDPR may be significant. The GDPR provides that EEA member states may introduce 
further  conditions,  including  limitations,  to  the  processing  of  genetic,  biometric  or  health  data  (and  other  special  category  data),  which  could  limit  our 
ability to collect, use and share personal data, or could cause our compliance costs to increase, ultimately having an adverse impact on our business.

EU GDPR (or UK GDPR) protected data must not be transferred outside of the EEA or UK, respectively, to a non-adequate country (i.e. a country 
that has not been recognized by the European Commission (in respect of the EU GDPR protected data) or the Secretary of State (in respect of the UK 
GDPR protected data) as providing an adequate level of protection for the transferred data), unless certain steps are taken to ensure an adequate level of 
protection. In practice, these extra steps would normally mean (i) entering into EU Standard Contractual Clauses (or, in case of the UK personal data, the 
UK Addendum to EU Standard Contractual Clauses or, alternatively, the IDTA i.e. the ICO's International Data Transfer Agreement) or putting in place 
another  data  transfer  mechanism,  (ii)  carrying  out  a  transfer  impact  assessment  and  where  necessary  to  protect  the  data,  implementing  supplementary 
measures. There are exemptions to these data transfer restrictions but these are interpreted narrowly.

The July 2020 invalidation by the Court of Justice of the European Union of the EU-U.S. Privacy Shield framework, one of the mechanisms used to 
legitimize the transfer of personal data from the EEA (and, post-Brexit, the UK to the U.S., has led to increased scrutiny on data transfers from the EEA 
(and UK) to the U.S. generally and may increase our costs of compliance with data privacy legislation due to the requirement to enter into EU Standard 
Contractual Clauses (or, in case of the UK personal data, the UK Addendum to EU Standard Contractual Clauses or the IDTA) and further extra steps set 
out above. In December 2022, the European Commission published its draft adequacy decision on the EU-US transfers of personal data - the new Data
Privacy  Framework,  or  EU-US  DPF.  Under  the  EU-US  DPF,  it  will  be  possible  to  transfer  EEA  personal  data  freely  to  the  US  recipient  that  has  self-
certified under the EU-US DPF regime, although this may be challenged in the European Union Court of Justice by EU based privacy advocates.

We  are  subject  to  the  supervision  of  local  data  protection  authorities  in  those  jurisdictions  where  we  are  established  or  otherwise  subject  to 

applicable law.

We depend on third parties in relation to provision of our services, a number of which process personal data on our behalf. With such providers we 
are legally required to enter into contractual arrangements which contain the minimum terms set out in the GDPR (and the UK GDPR), including to ensure 
that  they  process  personal  data  only  according  to  our  instructions,  and  that  they  have  adequate  technical  and  organizational  security  measures  in  place. 
Where personal data is being transferred outside the EEA (or the UK), it must be done in compliance with applicable data export requirements. Any failure 
by us or third parties to comply with applicable data laws, could lead to a security or privacy breach, regulatory enforcement, or regulatory, reputational or 
financial harm.

U.S. Healthcare Reform

The United States and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to change the 
healthcare system in ways that could affect our ability to sell our products profitably. Among policy makers and payors in the United States and elsewhere, 
there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality or expanding 
access.  Additional  healthcare  reform  efforts  have  sought  to  address  certain  issues  related  to  the  COVID-19  pandemic.  Current  and  future  legislative 
proposals to further reform healthcare or reduce healthcare costs may limit coverage of or lower reimbursement for the procedures associated with the use 
of our products. The cost containment measures that payors and providers are instituting and the effect of any healthcare reform initiative implemented in 
the future could impact our revenue from the sale of our products.

We expect additional state and federal healthcare reform measures to be adopted in the future, any of which could limit the amounts that federal and 
state governments will pay for healthcare products and services, which could result in reduced demand for our products or additional pricing pressure. We 
cannot, however, predict the ultimate content, timing or effect of any healthcare reform legislation or action, or its impact on us, and healthcare reform 
could increase compliance costs and may adversely affect our future business, operations and financial results.

Human Capital Management 

Our human capital strategy is comprehensive and leverages our work practices and collaborative culture. As of December 31, 2023, we employed 

584 people globally, most of whom were full-time employees.

Our Culture 

We strive to foster an inclusive, engaging, and safe work environment where employees want to grow their careers. We promote understanding of 
our mission, vision, and values and create strong relationships with our employees through various engagement and career development initiatives. For 
example, we hold quarterly Town Hall meetings with all employees to provide them with an open forum to ask questions, voice any concerns, and provide 
input on our corporate goals and vision for the future.

Diversity, Equity, and Inclusion: The keystone of our diversity strategy is mutual respect and fostering a sense of belonging – we want everyone to 
feel  welcome  and  comfortable  in  our  organization  and  feel  that  they  are  supported  in  growing  their  career.  Our  workforce  consists  of  individuals  from 
countries all over the world, representing many different faiths, languages, backgrounds, and cultures. We believe that our diversity is one of our greatest 
strengths. We are committed to creating and maintaining an inclusive workplace in which all employees have an opportunity contribute to the success of 
the business. This commitment is embedded in our company policies and human capital management practices.

We  have  adopted  policies  to  promote  compliance  with  laws  and  regulations  as  well  as  to  foster  a  respectful  workplace  for  all  employees.  These 
policies  include  a  code  of  business  conduct  and  ethics,  an  insider  trading  policy,  a  Regulation  FD  policy,  a  sexual  harassment  policy,  a  regulated
fraternization policy, and a whistleblower policy. Along with an overview of the company, our culture and expectations, training on these policies is a key 
component of our employee onboarding process.

Health and Safety: We are committed to maintaining compliance with laws and regulations surrounding the health and safety of our employees and 
strive to follow best practices in our operations. We require relevant employees to complete workplace safety training before performing any job duties that 
entail potential health hazards, such as trainings for employees who handle hazardous chemicals and biohazardous materials. 

Talent Attraction, Retention, and Development 

We continually seek exceptionally talented and dedicated people to join our team to help shape both our future and the future of transplant medicine. 
In recent years, the focus of our recruitment efforts has been centered on finding talent for the NOP and our engineering, manufacturing, and supply chain
operations.  Since  the  launch  of  our  aircraft  operations  in  2023,  we  are  also  seeking  additional  resources  in  the  field  of  logistics  and  aviation,  including 
logistics  coordinators,  pilots  and  aviation  mechanics.  We  aim  to  hire  people  with  the  right  skill  sets,  growth  mindset,  and  work  ethic  to  drive  business 
results and help us achieve our goals. We provide relocation benefits to eligible employees whom we request to move in connection with their employment 
with the objective of attracting and deploying top talent.

Compensation  and  Benefits:  We  offer  competitive  compensation  and  benefits  in  an  exciting,  demanding,  and  fast-paced  work  environment.  We 
provide employee benefits to eligible employees to promote personal health and well-being and to provide certain financial security and protection upon 
retirement or in the event of death, disability or illness. These benefits to eligible employees include a 401(k) retirement plan with an employer matching 
contribution, health insurance (including medical, dental, and vision), life insurance, short- and long-term disability insurance, and paid time off policies. 
We offer an employee stock purchase plan to facilitate broad-based stock ownership by our employees. 

Career  Development:  We  are  proud  to  have  a  work  environment  that  promotes  continued  development  for  our  employees.  Each  employee  is 
provided  formal  written  feedback,  at  least  annually,  and  together  with  his/her  manager,  develops  individual  goals  that  are  derived  from  our  overall 
corporate  and  financial  goals.  Moreover,  we  collaborate  with  our  employees  to  provide  customized  career  development  plans  as  well  as  general  and 
targeted training curricula based on their roles.

Item 1A. Risk Factors. 

An investment in our common stock involves risks. The following risks and all of the other information contained in this Annual Report on Form 10-
K should be considered carefully before investing in our common stock. The risks described below are those that we believe are the material risks that we 
face. If any of the following risks actually occurs, our business, prospects, operating results and financial condition could suffer materially, the trading 
price of our common stock could decline and investors could lose all or part of their investment. The risks and uncertainties described below are not the 
only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our 
business. See “Forward-Looking Statements” in this Annual Report on Form 10-K. 

Risks Related to Our Financial Position and Need for Additional Capital 

We have incurred substantial losses since our inception and have never generated net income on an annual basis. 

Since our inception, we have incurred significant operating losses. Our ability to generate revenue sufficient to achieve sustained profitability will 
depend  on  the  continued  growth  in  customer  utilization  of  our  OCS  products  and  services.  We  generated  revenue  of  $241.6  million,  $93.5  million  and 
$30.3  million  for  the  years  ended  December  31,  2023,  2022  and  2021,  respectively,  and  incurred  net  losses  of  $25.0  million,  $36.2  million  and  $44.2 
million for these same years. As of December 31, 2023, we had an accumulated deficit of $503.7 million. To date, we have funded our operations primarily 
with proceeds from sales of equity, borrowings under loan agreements, issuance of our 1.50% convertible senior notes due 2028, or our Notes, and revenue 
from clinical trials and commercial sales of our OCS products and services. Our losses have resulted principally from costs incurred in connection with our 
research and development, clinical trials, manufacturing and commercialization activities, including the development of our NOP. 

We expect our operating and capital expenditures will continue to increase for the foreseeable future as we focus on growing commercial sales of 
our products in both the U.S. and select non-U.S. markets, including growing our NOP and expanding our NOP offerings to include transportation logistics 
services,  including  the  acquisition  of  additional  aircraft  to  support  aviation  transportation;  growing  our  commercial  team,  which  will  pursue  increasing 
commercial sales of our OCS products; scaling our manufacturing operations; continuing research and development for our next generation OCS products; 
and seeking regulatory clearance for new products and product enhancements, including new indications, in both the U.S. and select non-U.S. markets. The 
timing and amount of our operating and capital expenditures will depend on many factors, including: 

•

•

•

•

•

•

•

•

•

•

the amount of product revenue generated by sales of our OCS Consoles, OCS Perfusion Sets and OCS Solutions and other products that may 
be approved in the United States and select non-U.S. markets, revenue generated by our services, and growth of the NOP; 

the costs and expenses of expanding our U.S. and non-U.S. commercial infrastructure and our manufacturing operations;

the extent to which our OCS products are adopted by the transplant community;

the ability of our customers to obtain adequate reimbursement from third-party payors for procedures performed using the OCS products;

the costs incurred in our efforts to operate and grow our NOP, including the costs and timing of growing our logistics capabilities, inclusive of 
acquiring additional aircraft for our aviation transportation services;

the costs and timing of research and development of the next generation of OCS products; 

the degree of success we experience in commercializing our OCS products for additional indications;

the  costs,  timing  and  outcomes  of  any  future  clinical  studies  and  regulatory  reviews,  including  to  seek  and  obtain  approvals  for  the  next 
generation of OCS products or for new indications for our OCS products;

the emergence of competing or complementary technologies;

the number and types of future products we develop and commercialize;

27

 
•

•

the costs of preparing, filing and prosecuting patent applications and maintaining, enforcing and defending intellectual property-related claims; 
and

the level of our selling, general and administrative expenses.

Because of the numerous risks and uncertainties associated with product development and commercialization, we are unable to accurately predict 

the timing or amount of increased expenses or when, or if, we will be able to achieve or maintain profitability.

Our existing and any future indebtedness could adversely affect our ability to operate our business. 

As  of  December  31,  2023,  our  outstanding  principal  balance  of  long-term  debt  under  our  credit  agreement  with  Canadian  Imperial  Bank  of 
Commerce, or CIBC, was $60.0 million, which we refer to as the CIBC Credit Agreement. Our payment obligations under the CIBC Credit Agreement 
reduce cash available to fund working capital, capital expenditures, research and development and general corporate needs. In addition, indebtedness under 
the  CIBC  Credit  Agreement  bears  interest  at  a  variable  rate,  making  us  vulnerable  to  increases  in  market  interest  rates.  If  market  rates  increase 
substantially, we will have to pay additional interest on this indebtedness, which would further reduce cash available for our other business needs. We may 
not have sufficient funds, and may be unable to arrange for additional financing, to pay the amounts due under or refinance our indebtedness under the 
CIBC Credit Agreement, which is repayable in equal monthly installments starting in July 2026 until its maturity in July 2027.

Our  obligations  under  the  CIBC  Credit  Agreement  are  secured  by  substantially  all  of  our  assets  and  the  assets  of  our  wholly-owned  material
subsidiaries,  subject  to  certain  exceptions.  The  security  interest  granted  over  our  assets  could  limit  our  ability  to  obtain  additional  debt  financing.  In 
addition,  the  CIBC  Credit  Agreement  contains  covenants  requiring  certain  financial  performance  metrics  that  restrict  our  activities,  including  (x)  a 
requirement to maintain a minimum liquidity amount of the greater of either (i) the consolidated adjusted EBITDA loss (or gain) for the trailing four month 
period (only if EBITDA is negative) and (ii) $10.0 million, and (y) a requirement to maintain total net revenue of at least 75% of the level set forth in the 
total revenue plan presented to CIBC. Failure to comply with the covenants in the CIBC Credit Agreement, including the financial covenants, could result 
in the acceleration of our obligations under the CIBC Credit Agreement, which are also subject to acceleration upon the occurrence of specified events of 
default,  including  payment  default,  change  in  control,  bankruptcy,  insolvency,  certain  defaults  under  other  material  debt,  certain  events  with  respect  to 
regulatory approvals and a material adverse change in our business, operations or other financial condition. If an event of default (other than certain events 
of bankruptcy or insolvency) occurs and is continuing, CIBC may declare all or any portion of the outstanding principal amount of the borrowings plus 
accrued  and  unpaid  interest  to  be  due  and  payable.  Upon  the  occurrence  of  certain  events  of  bankruptcy  or  insolvency,  all  of  the  outstanding  principal 
amount  of  the  borrowings  plus  accrued  and  unpaid  interest  will  automatically  become  due  and  payable.  If  such  acceleration  were  to  occur,  it  would 
materially and adversely affect our business, financial condition, operating results, cash flows and prospects.

Our  outstanding  indebtedness,  combined  with  our  other  financial  obligations,  could  increase  our  vulnerability  to  adverse  changes  in  general 
economic,  industry  and  market  conditions,  limit  our  flexibility  in  planning  for,  or  reacting  to,  changes  in  our  business  and  the  industry  and  impose  a 
competitive  disadvantage  compared  to  our  competitors  that  have  less  debt  or  better  debt  servicing  options.  See  “Item  7.  Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Long-term Debt” in this Annual Report on Form 10-K.

Servicing our 1.50% convertible senior notes due 2028 requires a significant amount of cash, and we may not have sufficient cash flow to pay 

our debt. 

In  May  2023,  we  issued  $460.0  million  aggregate  principal  amount  of  the  Notes,  pursuant  to  that  certain  indenture  dated  as  of  May  11,  2023, 
between us as issuer, and U.S. Bank Trust Company, National Association, as trustee. Our ability to make scheduled payments of the principal of, to pay 
interest  on,  or  to  refinance  our  indebtedness,  including  the  Notes,  depends  on  our  future  performance,  which  is  subject  to  many  factors,  including, 
economic, financial, competitive and other, beyond our control. If our business does not generate cash flow from operations sufficient to service our debt 
and  make  necessary  capital  expenditures,  we  may  be  required  to  adopt  one  or  more  alternatives,  such  as  selling  assets,  restructuring  debt  or  obtaining 
additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance the Notes, which mature in 2028, will depend on the 
capital markets and our financial condition at such times. We may not be able to engage in any of these activities or engage in these activities on desirable 
terms, which could result in a default on our debt obligations, and limit our flexibility in planning for and reacting to changes in our business. 

28

 
We may not have the ability to raise the funds necessary to repurchase the Notes as required upon a fundamental change, and our future debt 

may contain limitations on our ability to repurchase the Notes.

Holders  of  the  Notes  will  have  the  right  to  require  us  to  repurchase  their  Notes  for  cash  upon  the  occurrence  of  a  fundamental  change  at  a 
fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any. A 
fundamental  change  may  also  constitute  an  event  of  default  or  prepayment  under,  and  result  in  the  acceleration  of  the  maturity  of,  our  then-existing 
indebtedness. We cannot guarantee that we will have sufficient financial resources, or will be able to arrange financing, to pay the fundamental change 
repurchase price in cash with respect to any Notes surrendered by holders for repurchase upon a fundamental change. In addition, restrictions under our 
then existing credit facilities or other indebtedness, if any, may not allow us to repurchase the Notes upon a fundamental change. Our failure to repurchase 
the Notes upon a fundamental change when required would result in an event of default with respect to the Notes which could, in turn, constitute a default 
under the terms of our other indebtedness, if any. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace 
periods, we may not have sufficient funds to repay the indebtedness and repurchase the Notes. 

Capped call transactions entered into in connection with the Notes may impact the value of our common stock.

In connection with the Notes, we entered into capped call transactions with certain financial institutions. The capped call transactions are expected 

to generally reduce the potential dilution upon conversion of the Notes into shares of our common stock.

In connection with establishing their initial hedges of the capped call transactions, these financial institutions or their respective affiliates may have 
entered  into  various  derivative  transactions  with  respect  to  our  common  stock  and/or  purchased  our  common  stock.  The  financial  institutions,  or  their 
respective  affiliates,  may  modify  their  hedge  positions  by  entering  into  or  unwinding  various  derivatives  with  respect  to  our  common  stock  and/or 
purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the maturity of the Notes. This activity may 
have an impact on the value of our common stock.

Our financial results may fluctuate from quarter to quarter, which makes our results difficult to predict and may cause our results to fall short 

of expectations. 

Our financial results may fluctuate from quarter to quarter due to a number of factors, including the availability of donor organs for transplantation, 
which is unpredictable and could impact the volume of transplant procedures performed at transplant centers using the OCS and demand for our NOP. Our 
revenue from sales may fluctuate significantly from quarter to quarter, and our future quarterly and annual expenses as a percentage of our revenue may be 
significantly  different  from  those  we  have  recorded  in  the  past.  In  addition,  the  timing  of  acquiring  additional  aircraft  for  our  aviation  transportation 
services is uncertain and the amount we incur for such acquisitions is likely to differ from quarter to quarter. Our financial results in some quarters may fall 
below expectations. Comparing our financial results on a period-to-period basis may not be meaningful, and past results may not be an indication of our 
future performance. Because the timing of organ transplant procedures is generally unpredictable, we have not experienced seasonality in our business from 
quarter to quarter.

29

 
Our ability to use our net operating losses and research and development credit carryforwards to offset future taxable income may be subject to 

limitations.

As  of  December  31,  2023,  we  had  federal  net  operating  loss,  or  NOL,  carryforwards  of  $376.4  million,  which  may  be  available  to  offset  future 
taxable income, of which $207.4 million of the total net operating loss carryforwards expire at various dates beginning in 2024, while the remaining $169.0 
million do not expire but are limited in their usage to an annual deduction equal to 80% of annual taxable income. As of December 31, 2023, we had state 
net operating loss carryforwards of $328.8 million, which may be available to offset future taxable income and expire at various dates beginning in 2030. 
As  of  December  31,  2023,  we  also  had  U.S.  federal  and  state  research  and  development  tax  credit  carryforwards  of  $10.7  million  and  $6.5  million, 
respectively, which may be available to offset future tax liabilities. Our U.S. federal research and development tax credit carry forwards expire beginning in 
2024.  A  material  portion  of  these  NOL  and  tax  credit  carryforwards  could  expire  unused  and  be  unavailable  to  offset  future  income  tax  liabilities.  In 
addition,  in  general,  under  Sections  382  and  383  of  the  Internal  Revenue  Code  of  1986,  as  amended,  or  the  Code,  a  corporation  that  undergoes  an 
“ownership change,” generally defined as a greater than 50% change by value in its equity ownership over a three-year period, is subject to limitations on 
its ability to utilize its pre-change NOLs, its research and development credit carryforwards and its disallowed interest expense carryovers to offset future 
taxable  income.  Our  existing  NOLs  and  research  and  development  credit  carryforwards  may  be  subject  to  limitations  arising  from  previous  ownership 
changes.  In  addition,  future  changes  in  our  stock  ownership,  some  of  which  might  be  beyond  our  control,  could  result  in  an  ownership  change  under 
Section 382 of the Code. Our NOLs and credits may also be impaired under state law. For these reasons, if we determine that an ownership change has 
occurred or in the event we experience a change of control, we may not be able to utilize a material portion of the NOLs, research and development credit 
carryforwards or disallowed interest expense carryovers incurred prior to 2019. 

Furthermore, our ability to utilize our NOLs or credits is conditioned upon our attaining profitability and generating U.S. federal and state taxable 
income. As described above, we have incurred significant net losses since our inception and anticipate that we will continue to incur significant losses for 
the foreseeable future; and therefore, we do not know whether or when we will generate the U.S. federal or state taxable income necessary to utilize our 
NOL or credit carryforwards. Under the Tax Cuts and Jobs Act, or TCJA, NOLs arising in taxable years beginning after December 31, 2017 will not be 
subject to expiration. In addition, the deduction for NOLs in any taxable year is limited to 80% of annual taxable income in respect of NOLs generated 
during or after 2018. The TCJA also reduced the corporate income tax rate to 21%, from a prior rate of 35%. This may cause a reduction in the potential 
economic benefit of our NOLs and other available deferred tax assets. 

We  may  need  to  raise  additional  funding,  which  might  not  be  available  on  favorable  terms  or  at  all.  Raising  additional  capital  may  cause 

dilution to our shareholders.

Until such time, if ever, that we can generate substantial revenue sufficient to achieve sustained profitability, we may need to finance our operations 
through a combination of equity offerings, debt financings and strategic alliances. We also may elect to raise additional funds because we believe market 
conditions are attractive or as a risk mitigation measure. Additional capital might not be available when we need it, and our actual cash requirements might 
be greater than anticipated. If we require additional capital at a time when investment in our industry or in the marketplace in general is limited, we might 
not be able to raise funding on favorable terms, if at all. If we are not able to obtain financing on terms favorable to us, we may need to significantly delay, 
scale back or discontinue our development or commercialization activities, sell or license to third parties some or all of our assets or merge with another 
entity or may be forced to reduce or terminate our operations. 

If  we  raise  additional  funds  through  the  issuance  of  equity  or  convertible  securities,  the  issuance  of  these  securities  could  dilute  shareholders' 
percentage  ownership  in  our  company.  Furthermore,  newly  issued  securities  may  have  rights,  preferences  or  privileges  senior  to  those  of  common 
shareholders. If we raise additional funds through additional debt financing, we may need to dedicate a substantial additional portion of any operating cash 
flows  to  the  payment  of  principal  and  interest  on  such  indebtedness.  The  terms  of  any  debt  financing  also  could  impose  significant  restrictions  on  our 
operations.

Risks Related to Product Commercialization and Development 

Our long-term growth depends on our ability to expand access to the OCS through our NOP.

We  have  developed  the  NOP,  an  innovative  turnkey  solution  to  provide  outsourced  organ  retrieval  and  OCS  organ  management,  to  provide 
transplant programs with a more efficient process to procure donor organs with the OCS. We believe the NOP will continue to expand access and use of the 
OCS.  However,  we  may  not  be  successful  in  the  continued  development  of  our  NOP,  which  will  depend  on  recruiting,  training  and  retaining  qualified 
surgeons and pilots and establishing and maintaining effective coordination with transplant centers and regional Organ Procurement Organizations to locate 
donor organs and recipients. We may not be able to recruit, train and retain surgeons, pilots and other qualified personnel, including due to demand for their 
capabilities and competitive compensation offered by other employers. In order to recruit, train and retain such highly qualified employees, we also may 
need to increase the level, or change the form or composition, of the compensation that we pay to them, which would increase our expenses.

In addition to our own surgical and clinical personnel, we utilize a network with a limited number of partners for organ retrieval, organ preservation 
and transportation services offered through our NOP. If any of these relationships are interrupted or terminated, or if one or more partners are unable or 
unwilling to fulfill their obligations for any reason, NOP services to our customers may be interrupted. We also may not be able to identify or negotiate 
with  additional  partners  on  terms  that  are  commercially  reasonable  to  us.  The  interruption  or  failure  to  retain  or  replace  partners  for  our  NOP  would 
negatively impact our operations and financial results. Furthermore, the expenses incurred by us to customers who participate in our NOP are dependent on 
many different market dynamics, including the cost of fuel and other transportation costs. Additional expenses incurred by our NOP could adversely affect 
our business, gross margin, financial condition, operating results, cash flows and prospects. 

We will need to increase our manufacturing and sterilization capacity in the future and may encounter problems at our manufacturing facility 

or otherwise. 

In order to manufacture the OCS in quantities sufficient to meet our anticipated commercial opportunity, we will need to continue to increase our 
manufacturing  capabilities  and  retain  third  parties  to  sterilize  our  products.  We  may  encounter  technical  challenges  to  increasing  the  scale  at  which  we 
manufacture the OCS, including with respect to material procurement and quality control and assurance. An increase in production could make it more 
difficult for us to comply with quality system regulations or other applicable requirements that are currently enforced by the FDA and other regulatory 
authorities,  or  that  may  be  introduced  in  the  future,  in  both  the  United  States  and  in  other  countries.  Commercial  scale  production  of  the  OCS  on  a 
continuing basis also will require us to continue to hire and retain additional management and technical personnel who have the necessary manufacturing 
experience and skills. We might not successfully identify, hire or retain qualified personnel on a timely basis or at all. To maintain quality of our OCS, we 
may not be able to scale production of our OCS products at a rate that meets customer demand for our products. Our inability to increase the scale of our 
manufacturing of the OCS could impair our ability to generate revenue and adversely affect market acceptance of our product. 

In addition, all of our manufacturing operations are conducted at a single facility in Andover, Massachusetts. Any interruption in operations at this 
location could result in our inability to satisfy product demand. Despite our efforts to safeguard this facility, including acquiring insurance on commercially 
reasonable terms, adopting environmental health and safety protocols and utilizing off-site storage of computer data, a number of factors could damage or 
destroy our manufacturing equipment or our inventory of component supplies or finished goods, cause substantial delays in our operations, result in the 
loss of key information, and cause us to incur additional expenses, including: 

•

•

•

•

•

•

operating restrictions, partial suspension or total shutdown of production imposed by regulatory authorities;

equipment malfunctions or failures;

technology malfunctions;

work stoppages;

damage to or destruction of the facility due to natural disasters or other events; or

regional or local power shortages.

31

 
Our insurance may not cover our losses in any particular case, or insurance may not be available on commercially reasonable terms to cover certain 
of these catastrophic events. In addition, regardless of the level of insurance coverage, damage to our facilities or any disruption that impedes our ability to 
manufacture  the  OCS  in  a  timely  manner  could  materially  and  adversely  affect  our  business,  financial  condition,  operating  results,  cash  flows  and 
prospects. 

We rely on third-party vendors to sterilize our disposable sets prior to sale. If vendors are unable to sterilize our products, whether due to capacity, 
availability of materials for sterilization, regulatory or other constraints, including federal and state regulations on the use of ethylene oxide used in the 
sterilization process, we will not be able to sell products until we can retain an alternative vendor to sterilize the products. We may be unable to transition to 
alternative methods of sterilization in a timely or cost-effective manner or at all, which could harm our business and results of operations.

Our results of operations could be materially harmed if we are unable to accurately forecast customer demand for our products and manage our 

inventory.

We seek to maintain sufficient levels of inventory, including our OCS Perfusion Sets, in order to protect ourselves from supply interruptions and to 
support the demand from customers, but keep limited components, sub-assemblies, materials and finished products on hand. To ensure adequate inventory 
supply  and  manage  our  operations  with  our  suppliers,  we  forecast  anticipated  materials  requirements  and  demand  for  our  products  in  order  to  predict 
inventory needs and then place orders with our suppliers based on these predictions. Our ability to accurately forecast demand for our products could be 
negatively affected by many factors, including the rate of transplantations, product recalls, failure to accurately manage our commercial strategy, product 
introductions by competitors, an increase or decrease in customer demand for our products, our failure to accurately forecast customer acceptance of new 
products, changes to hospital capacity, staffing, procedure and protocol changes, unanticipated changes in general market conditions or regulatory matters 
and weakening of economic conditions or consumer confidence in future economic conditions. We also maintain inventory reserves at regional locations 
for  distribution  through  our  NOP.  If  we  are  not  able  to  maintain  sufficient  inventory  at  these  locations,  or  if  we  are  not  able  to  accurately  predict  the 
regional  demand  for  our  OCS  products,  we  will  incur  additional  costs  to  transport  inventory  to  our  regional  locations,  including  rebalancing  inventory 
amongst regional locations, and we may not be able to grow our commercial sales as anticipated.

Inventory levels in excess of customer demand may result in a portion of our inventory becoming obsolete or expiring, as well as inventory write-
downs  or  write-offs.  Conversely,  if  we  underestimate  customer  demand  for  our  products  or  our  own  requirements  for  components,  subassemblies  and 
materials, our manufacturing partners and suppliers may not be able to deliver components, sub-assemblies and materials to meet our requirements and our 
manufacturing  may  be  affected  by  the  impact  of  inflation  and  labor  shortages  on  our  suppliers,  which  could  result  in  inadequate  inventory  levels  or 
interruptions, delays or cancellations of deliveries to our customers, any of which would damage our reputation, customer relationships and business. In 
addition,  several  components,  sub-assemblies  and  materials  incorporated  into  our  products  require  lengthy  order  lead  times,  and  additional  supplies  or 
materials may not be available when required on terms that are acceptable to us or our manufacturing partners, or at all, and our manufacturing partners and 
suppliers may not be able to allocate sufficient capacity in order to meet our increased requirements, any of which could have an adverse effect on our 
ability to meet customer demand for our products and our results of operations.

We aim to maintain strategic reserves of our OCS Perfusion Sets, but if we are not able to manufacture and assemble OCS Perfusion Sets at a rate
that will allow us to maintain these reserves, then we will be required to rely on alternative strategies to deliver OCS Perfusion Sets in a timely manner, 
which may impact our expenses and results of operations.

We  depend  heavily  on  the  success  of  the  OCS  and  it  gaining  additional  market  acceptance.  If  we  are  unable  to  continue  to  successfully 

commercialize the OCS, our business may fail. 

We  have  invested  substantial  efforts  and  financial  resources  in  the  development  of  the  OCS,  educating  surgeons,  transplant  centers,  Organ 
Procurement  Organizations  and  private  and  public  payors  of  the  benefits  of  the  OCS,  providing  services  related  to  the  OCS  and  launching  our  NOP. 
Although we have received PMAs from the FDA for each of our three OCS products, we might not be able to continue to successfully commercialize the 
OCS for these approved indications or obtain approvals for additional indications or in additional jurisdictions on our planned timing or at all. Our ability to 
generate product revenue and become profitable depends primarily on sales of OCS Perfusion Sets and OCS Solutions, which we refer to collectively as 
disposable sets. Our assumptions regarding demographic trends, donor organ availability and the use of transplantation as a treatment for end-stage organ 
failure may prove to be incorrect. 

32

 
We  expect  that  we  will  need  to  continue  to  demonstrate  to  surgeons,  transplant  center  program  directors,  Organ  Procurement  Organizations  and 
private and public payors that the OCS potentially results in some or all of the following: improvements in post-transplant clinical outcomes, increases in 
the utilization of donor organs, expansion of the pool of potential donors and reduction in the total cost of care as compared to available alternatives. 

Surgeons, transplant centers and private and public payors often are slow to adopt new products, technologies and treatment practices that require 
additional  upfront  costs  and  training.  The  cost  of  the  OCS  significantly  exceeds  the  cost  of  cold  storage  preservation.  In  addition,  our  international 
customers  and  some  U.S.  customers  use  a  direct  acquisition  model  pursuant  to  which  transplant  centers  train  their  own  teams  for  retrieval  and  organ 
management using the OCS rather than utilizing our NOP. Surgeons may not be willing to undergo training to use the OCS, may decide the OCS is too 
complex to adopt without appropriate training and may choose not to use the OCS, which may limit the adoption of the OCS under the direct acquisition 
model. Based on these and other factors, transplant center program directors, Organ Procurement Organizations and private and public payors may decide 
that the benefits of the OCS do not outweigh its costs. In addition, adoption of the OCS may be constrained by the capacity of individual transplant centers 
to perform transplants due to factors such as the number of its surgeons trained on the use of the OCS. As a result, demand for the OCS could be materially 
lower than we expect it to be, which would materially and adversely affect our business, financial condition, operating results, cash flows and prospects.

We must continue to educate surgeons, transplant centers and private and public payors and demonstrate the merits of the OCS compared with 

cold storage or new competing technologies.

Directors of transplant programs are key decision-makers in the adoption of novel medical devices used in organ transplantation. An important part 
of  our  commercialization  efforts  is  to  educate  transplant  center  program  directors  and  other  surgeons  on  the  relative  merits  of  the  OCS.  Our  success 
depends,  in  large  part,  on  effectively  marketing  and  educating  program  directors  and  other  surgeons  about  the  benefits  of  the  OCS  and  our  NOP. 
Acceptance  of  the  OCS  also  depends  on  educating  program  directors,  other  surgeons  and  private  and  public  payors  as  to  the  distinctive  characteristics, 
perceived  medical  and  economic  benefits,  safety,  ease  of  use  and  cost-effectiveness  of  the  OCS  and  our  NOP.  If  program  directors,  other  surgeons  and 
private and public payors do not find our body of published clinical evidence and data compelling or wish to wait for additional studies, they may choose 
not to use or provide coverage and reimbursement for our products and NOP Services. Currently, most universal national healthcare systems outside of the 
United States do not reimburse transplant centers for the use of the OCS and reimbursement in international markets may require us to undertake additional 
clinical studies. 

In  addition,  the  long-term  effects  of  our  OCS  following  transplantation  are  not  yet  known.  Certain  surgeons,  transplant  centers  and  private  and 
public payors may prefer to see longer-term safety and efficacy data than we have produced. We cannot provide assurance that any data that we or others 
may  generate  in  the  future  will  be  consistent  with  that  observed  in  our  existing  clinical  studies.  In  addition,  as  the  NOP  expands  access  to  the  OCS, 
transplant surgeons may increasingly rely on clinical data regarding the organ provided to them by our clinical specialists and surgeons. We are responsible 
for the clinical data regarding the organ that is provided to transplant surgeons who participate in the NOP.

Our  long-term  growth  depends  on  our  ability  to  improve  the  OCS  platform,  including  by  developing  the  next  generation  of  our  products  or 

expanding into new indications. 

Our business plan contemplates that we will continue to improve the OCS platform, including by developing the next generation of our products or 
expanding into additional organs. Developing such new or modified products is expensive and time-consuming and diverts management’s attention away 
from current operations. The success of any new product offering or product enhancements to our OCS platform will depend on several factors, including 
our ability to: 

•

•

•

•

•

•

properly identify and anticipate surgeon and patient needs;

develop and introduce new products and product modifications in a timely manner;

avoid infringing upon, misappropriating or otherwise violating the intellectual property rights of third parties;

demonstrate the safety and efficacy of new products and product modifications;

obtain necessary regulatory clearances or approvals;

comply with regulations regarding the marketing of new products or product modifications;

33

 
•

•

•

provide adequate training to potential users of our products;

receive adequate coverage and reimbursement for procedures performed with our products; and

develop an effective commercialization effort.

If we are not successful in expanding our indications and developing the next generation of our products, our ability to increase our revenue may be 

impaired, which could materially and adversely affect our business, financial condition, operating results, cash flows and prospects.

We  may  not  fully  realize  the  anticipated  benefits  of  our  completed  or  future  acquisitions,  joint  ventures,  and  strategic  investments,  such 

transactions may expose us to additional risks. 

On August 2, 2023, we acquired certain assets related to lung and heart perfusion technology from Bridge to Life Ltd. and its subsidiary Tevosol, 
Inc., or together Bridge to Life. In addition, on August 16, 2023, we acquired Summit, an aviation business. We have separately acquired 13 fixed-wing 
aircraft, and intend to acquire additional fixed-wing aircraft, that will be operated as part of our NOP. Utilization of these acquired assets and integration of 
Summit, may be complex, costly and time consuming and we may face unanticipated issues, expenses and liabilities. We may not successfully or profitably 
utilize newly acquired assets or integrate, operate, maintain and manage any newly acquired operations or employees. Further development of the assets we 
acquired  from  Bridge  to  Life,  or  the  Bridge  to  Life  Assets,  will  require  extensive  clinical  development,  management  of  nonclinical,  clinical  and 
manufacturing  activities.  In  addition,  we  may  decide  that  only  certain  of  the  acquired  technology  is  useful  for  the  next  generation  of  the  OCS,  or  that 
integration of the acquired technology is not feasible or is too costly. We also may face challenges integrating Summit into our organization. We have never 
provided  aviation  transportation  services  prior  to  the  acquisition  and  will  depend  on  the  management  team  of  Summit  for  the  successful  operation  and 
integration into our NOP services offering. Even if we are able to utilize the Bridge to Life Assets and integrate Summit or any other acquired assets or 
businesses successfully, we may not realize the expected benefits of the transactions. These are the Company’s first acquisitions, and we may need to invest 
in additional business processes and systems to support the Summit integration or to utilize the Bridge to Life Assets. Such additional costs may offset the 
financial benefits that may be realized from the acquisitions. We also may suffer the loss of key employees and strategic partners of Summit and it may be 
difficult to implement our corporate culture. There also may be increased risk due to integrating financial reporting and internal control systems of Summit. 
We may review additional acquisition, joint ventures and strategic investment opportunities to expand our current product offerings, increase the size and 
geographic scope of our operations or otherwise offer growth and operating efficiency opportunities. There can be no assurance that we will be able to 
identify  suitable  candidates  or  consummate  future  transactions  on  favorable  terms.  If  required,  the  financing  for  future  transactions  could  result  in  an 
increase  in  our  indebtedness,  dilute  the  interests  of  our  shareholders  or  both.  The  purchase  price  for  some  acquisitions  or  joint  ventures  interests  may 
include additional amounts to be paid in cash in the future, a portion of which may be contingent on the achievement of certain future operating results of 
the  acquired  business.  If  the  performance  of  any  such  acquired  business  or  joint  venture  exceeds  such  operating  results,  then  we  may  incur  additional 
charges  and  be  required  to  pay  additional  amounts.  Our  failure  to  successfully  utilize  any  acquired  assets,  complete  the  integration  of  any  acquired 
business, including retention of key employees, customers and strategic partners, achieve the long-term plan for such assets or businesses, as well as any 
other adverse consequences associated with our acquisition and investment activities, could have an adverse effect on our business. Any acquisition may
also disrupt our ongoing business, divert resources, increase our expenses, and distract our management from our ongoing operations. 

We depend on a limited number of customers for a significant portion of our revenue and the loss of, or a significant shortfall in demand from, 

these customers could have a material adverse effect on our financial condition and operating results.

We  generate  a  significant  amount  of  our  revenue  from  a  limited  number  of  customers.  However,  our  customers  may  not  continue  to  utilize  our 
products or services at current levels, pricing, or at all, and our revenue could fluctuate significantly due to changes in economic conditions, the use of other 
methods for organ preservation, such as cold storage, or the loss of, reduction of business with, or less favorable terms with any of our largest customers. 
Our  future  success  will  depend  upon  the  timing  and  volume  of  business  from  our  largest  customers  and  the  financial  and  operational  success  of  these 
customers. If we were to lose a key customer or have a key customer significantly reduce their volume of business with us, our revenue may be materially 
reduced, which would materially and adversely affect our business, financial condition, operating results, cash flows and prospects. 

34

 
Substantially  all  of  our  U.S.  customers  now  participate  in  our  NOP  and  our  success  will  depend  on  our  ability  to  maintain  the  function  and 
efficiency, while increasing capacity and capability, of the NOP. If we are unable to deliver OCS products to customers through their participation in the 
NOP, our revenue would be materially reduced, which would materially and adversely effect our business, financial condition, operating results, cash flows 
and prospects.

We depend on single-source suppliers and, in a few cases, sole-source suppliers for many of the components used in the OCS. 

We rely on single-source suppliers and, in a few cases, sole-source suppliers for many of the components used in the OCS. For example, each of 
Fresenius Kabi Austria GmbH and Fresenius Kabi AB, which we refer to collectively as Fresenius, is our single-source supplier of OCS Solutions for the 
OCS Lung and the OCS Heart, respectively. While we have manufacturing and supply agreements with certain of our suppliers, for most of our suppliers, 
we place purchase orders on an as-needed basis. Our suppliers could discontinue the manufacturing or supply of these components at any time. We do not 
carry a significant inventory of some of these components. Our suppliers may not be able to meet our demand for their products, either because of acts of 
nature, the nature of our agreements with those manufacturers or our relative importance to them as a customer, and our manufacturers may decide in the 
future to discontinue or reduce the level of business they conduct with us. In addition, if these suppliers are unable to deliver components to us, whether 
due  to  a  labor  shortage,  slow  down  or  stoppage,  or  for  any  other  reason,  we  would  be  required  to  seek  alternative  suppliers.  We  might  not  be  able  to 
identify and qualify additional or replacement suppliers for any of these components quickly or at all or without incurring significant additional costs. We 
cannot guarantee that we will be able to establish alternative relationships on similar terms, without delay or at all. 

We also may choose to establish our own manufacturing process of certain components and we may not be successful in doing so. For example, we 
will need to seek FDA approval for any component design we choose to manufacture, which may not be granted in a reasonable time, or at all. In addition, 
the components we design may not be successful or may not provide a functional or economic benefit compared to similar components manufactured by 
third parties. If we choose to establish our own manufacturing process of components of the OCS, we may be required to procure additional raw materials 
for such processes, which may not be available. We may also face regulatory delays or be required to seek additional regulatory clearances or approvals if 
we experience any delay or deficiency in the quality of products obtained from suppliers or if we have to replace our suppliers. In addition, many of the 
components used in the OCS are specifically designed for use in the OCS, which means that off-the-shelf components may not be available as substitutes. 

Establishing additional or replacement suppliers for any of these materials or components, if required, or any supply interruption from our suppliers, 
could limit our ability to manufacture our products, result in production delays and increased costs and adversely affect our ability to deliver products to 
our customers on a timely basis. Our inability to obtain sufficient quantities of components for the OCS also could adversely affect development of the next 
generation of the OCS. If we are not able to identify alternate sources of supply for the components, we might have to modify our product to use substitute 
components, which could lead to additional regulatory obligations that could impact our marketing ability, cause delays in shipments, increase design and 
manufacturing costs and increase prices for our products. Any such modified product might not be as effective as the predecessor product or might not gain 
market  acceptance.  This  could  lead  to  customer  dissatisfaction  and  damage  to  our  reputation  and  could  materially  and  adversely  affect  our  business, 
financial condition, operating results, cash flows and prospects. 

In  addition  to  our  aviation  transportation  services,  we  also  depend  on  third  parties  to  transport  donor  organs  and  medical  personnel  for  our 

NOP, and limited availability of, or increases in the cost of, transportation could limit our ability to grow or operate the NOP. 

In  addition  to  our  aviation  transportation  services,  our  NOP  depends  on  the  use  of  a  third-party  network  of  private  aircraft  to  transport  medical 
personnel to retrieve donor organs and deliver donor organs to patients for transplantation. Reliance on private aircraft is subject to various risks, including 
those associated with change in fuel prices, work stoppages and weather-related operating hazards. In particular, private aircraft are occasionally in high 
demand and/or subject to price fluctuations based on market conditions. Further, availability is constrained by a limited number of private aircraft available 
in the United States and a limited number of qualified pilots. As a result, third-party private aircraft providers may not be able to prioritize our use of their 
services.

35

 
If  we  are  unable  to  obtain  flight  services  for  our  NOP  when  needed,  we  may  be  unable  to  utilize  our  NOP  to  satisfy  demand.  We  also  may  be 
required to seek alternative and, potentially more costly, flight services. Although the cost of flights is paid by our customers, a substantial increase in the 
cost of flight services, due to prolonged increases in fuel prices, lack of availability of aircraft or otherwise, may require us to incur additional costs to 
identify and obtain alternative flights or rebalance our inventory by shipping products to locations for which flight costs are less expensive or from which 
flights are more readily available, and customers may be unwilling or unable to incur higher costs of flights and therefore forgo use of our services and 
products for the retrieval of donor organs despite availability. Further, the capacity of our NOP is limited by the number of aircraft and pilots available for 
our use and as we continue to grow our NOP, we will be required to obtain access to a greater number of available aircraft and pilots.

We may not be able to achieve or maintain satisfactory pricing and margins for our products or services.

Manufacturers of medical devices have a history of price competition, and we can give no assurance that we will be able to achieve satisfactory 
prices for our products or maintain prices at the levels we have historically achieved. Any decline in the amount that payors reimburse our customers for 
OCS products or services could make it difficult for customers to continue using, or to adopt, our products and could create additional pricing pressure for 
us. If we are forced to lower the price we charge for our products or services, our gross margins will decrease, which will adversely affect our ability to 
invest in and grow our business. If we are unable to maintain our prices, or if our costs increase and we are unable to offset such increase with an increase 
in  our  prices,  our  margins  could  erode.  We  will  continue  to  be  subject  to  significant  pricing  pressure,  which  could  harm  our  business  and  results  of 
operations.

Price increases of the components used to manufacture our products and supply shortages could adversely affect our business and operating 

results.

The supply of raw materials to our component parts suppliers could be interrupted for a variety of reasons, including availability and pricing. We 
may experience supply chain disruptions due to general impacts of inflation and labor shortages and these disruptions to the supply chain could adversely 
affect our ability to meet commitments to customers. Significant price increases could adversely affect our results of operations and operating margins. In 
particular,  inflation,  changes  in  trade  policies,  the  imposition  of  duties  and  tariffs  and  public  health  crises  (such  as  the  COVID-19  pandemic)  could 
adversely impact the price or availability of raw materials and the components of our products. We may not be able to pass along increased component part 
prices to customers in the form of price increases or our ability to do so could be delayed. Consequently, our results of operations and financial condition 
may be adversely affected.

Our failure to compete effectively will harm our business and operating results. 

A broad range of medical device, pharmaceutical and biotechnology companies offer products, procedures and therapies that have the potential to
limit the demand for organ transplantation. Companies within this group vary depending on the type of organ. New therapies for COPD, which includes 
emphysema and chronic bronchitis, could limit the demand for lung transplants. Alternative products, procedures and therapies including ventricular assist
devices, cardiac rhythm management products, total artificial hearts, and drug therapies for the heart and surgical procedures could limit demand for heart 
transplants. Improved treatments for chronic diseases or conditions affecting the liver as well as efforts to develop artificial livers could limit the need for 
liver transplants. If demand for organ transplants decreases, sales of the OCS and its components will suffer. 

Other companies may develop technologies and products that result in improved patient outcomes or are safer, easier to use, less expensive or more 
readily accepted than the OCS. These products or technologies could make the OCS obsolete or noncompetitive and reduce demand for our OCS products. 
Many  of  these  providers  of  alternative  products,  procedures  and  therapies  have  greater  name  recognition,  significantly  greater  financial  resources  and 
expertise  in  research  and  development,  manufacturing,  preclinical  testing,  conducting  clinical  trials,  obtaining  regulatory  approvals  and  clearances  and 
marketing  and  selling  products  than  we  do.  Smaller  and  other  early  stage  companies  may  also  prove  to  be  significant  competitors,  particularly  through 
collaborative  arrangements  with  large  and  established  companies.  Third  parties  may  also  compete  with  us  in  recruiting  and  retaining  qualified  medical, 
engineering  and  management  personnel,  establishing  clinical  trial  sites  and  patient  registration  for  clinical  trials,  as  well  as  in  acquiring  technologies 
complementary to or necessary for our products or development programs or otherwise advantageous to our business. Our failure to compete effectively 
will harm our business and operating results. 

36

 
The clinical trial process that may be required to obtain future regulatory approvals is lengthy and expensive, with uncertain outcomes. 

Clinical trials are necessary to support PMA applications and may be necessary to support future PMA supplements for modified versions of our 
marketed device products. Conducting clinical trials is a complex and expensive process, can take many years and outcomes are inherently uncertain. For 
the development of the next generation of OCS products or the development of OCS products for additional organs, we may incur substantial expense for, 
and devote significant time to, clinical trials but cannot be certain that the product tested will ever generate revenue sufficient to cover the costs of trials. 
We may experience significant setbacks in clinical trials, even after earlier clinical trials showed promising results, and failure can occur at any time during 
the clinical trial process. Any of our products may malfunction or may produce undesirable adverse effects that could cause us or regulatory authorities to 
interrupt, delay or halt clinical trials. We, the FDA or another regulatory authority may suspend or terminate clinical trials. 

Successful results in early studies do not assure positive results in subsequent clinical trials. The data we collect from our preclinical studies and 
clinical trials may not be sufficient to support FDA or other regulatory clearance or approval. Additionally, the FDA may disagree with our interpretation of 
the data from our studies and trials. The FDA may conclude that the clinical trial design, conduct or results are inadequate to prove safety or effectiveness, 
and the FDA may require us to undertake expensive and lengthy additional trials, which may delay clearance or approval of products. 

Clinical  trials  often  require  enrollment  of  large  numbers  of  subjects,  who  may  be  difficult  to  identify,  recruit  and  maintain  as  participants  in  the 
clinical trial. As a condition to our PMA approvals, we are required to conduct post-market studies. For example, we have post-approval registries ongoing 
for all three of our organ products, including the OCS Lung Thoracic Organ Perfusion Registry, or TOP Registry, the OCS Heart Perfusion Registry, or 
OHP, and the OCS Liver Perfusion Registry, or OLP.

Adverse outcomes in post-approval studies can result in withdrawal of approval of a PMA or restrictions on the approval. We will need to conduct 
additional clinical studies to support use of the OCS in, and development of OCS products for, new organs, and potentially for commercialization of our 
products in additional foreign jurisdictions. Clinical trials in organ transplant are difficult to design and implement, take substantial time to conduct and are 
expensive.  The  results  of  clinical  trials  are  inherently  uncertain.  The  initiation  and  completion  of  any  studies  may  be  prevented,  delayed  or  halted  for 
numerous reasons. The following could adversely affect the costs, timing or successful completion of any clinical trial: 

•

•

•

•

•

•

•

•

we have been required and, prior to collecting clinical data in the future to support new PMA applications, may be required again to submit an 
IDE  application  to  the  FDA,  which  must  become  effective  prior  to  commencing  human  clinical  trials,  and  the  FDA  may  reject  our  IDE 
application and notify us that we may not begin investigational trials;

regulators and other comparable foreign regulatory authorities may disagree as to the design or implementation of our clinical trials;

regulators  and/or  IRBs,  or  other  reviewing  bodies  may  not  authorize  us  or  our  investigators  to  commence  a  clinical  trial,  or  to  conduct  or 
continue a clinical trial at a prospective or specific trial site;

we may not reach agreement on acceptable terms with prospective clinical trial sites, the terms of which can be subject to extensive negotiation 
and may vary significantly among different trial sites;

clinical trials may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical 
trials or abandon product development programs;

the  number  of  subjects  or  patients  required  for  clinical  trials  may  be  larger  than  we  anticipate,  enrollment  in  these  clinical  trials  may  be 
insufficient or slower than we anticipate, and the number of clinical trials being conducted at any given time may be high and result in fewer 
available patients for any given clinical trial, or patients may drop out of these clinical trials at a higher rate than we anticipate;

our third-party contractors, including those manufacturing or sterilizing our products, may fail to comply with regulatory requirements or meet 
their contractual obligations to us in a timely manner or at all;

we  might  have  to  suspend  or  terminate  clinical  trials  for  various  reasons,  including  a  finding  that  the  subjects  are  being  exposed  to 
unacceptable health risks;

we may have to amend clinical trial protocols or conduct additional studies to reflect changes in regulatory requirements or guidance, which we 
may be required to submit to an IRB and/or regulatory authorities for re-examination;

regulators, IRBs or other reviewing bodies may require or recommend that we or our investigators suspend or terminate clinical research for 
various reasons, including safety signals or noncompliance with regulatory requirements;

the cost of clinical trials may be greater than we anticipate;

we may be unable to recruit a sufficient number of clinical trial sites;

regulators  or  other  reviewing  bodies  may  fail  to  accept  as  satisfactory,  fail  to  approve,  or  subsequently  find  fault  with  our  manufacturing 
processes  or  facilities  of  third-party  manufacturers  with  which  we  enter  into  agreement  for  clinical  and  commercial  supplies,  the  supply  of 
devices or other materials necessary to conduct clinical trials may be insufficient, inadequate or not available at an acceptable cost, or we may 
experience interruptions in supply;

approval  policies  or  regulations  of  FDA  or  applicable  foreign  regulatory  agencies  may  change  in  a  manner  rendering  our  clinical  data 
insufficient for approval; and

our current or future products may have undesirable side effects or other unexpected characteristics. 

Failure can occur at any stage of clinical testing. For example, our clinical studies may produce negative or inconclusive results, and, in the future, 
we may decide, or regulators may require us, to conduct clinical and non-clinical testing in addition to those we have planned. After submission of our 
PMA applications for OCS Lung and OCS Heart, the FDA requested certain additional clinical analyses, technical information and clarifications as part of
the  agency’s  normal  review  process.  The  FDA  ultimately  approved  both  PMAs.  The  FDA  could  ask  us  to  conduct  additional  clinical  trials  or  submit 
additional evidence to support PMA applications in the future. Our failure to adequately demonstrate the safety and effectiveness of any product we may 
develop in the future would prevent receipt of regulatory clearance or approval and, ultimately, the commercialization of that product or indication for use. 
Even if our future products are cleared or approved in the United States, commercialization of our products in foreign countries would require marketing 
authorization from regulatory authorities in those countries. Authorization approval procedures vary among jurisdictions and can involve requirements and 
administrative review periods different from, and greater than, those in the United States, including additional preclinical studies or clinical trials. Any of 
these occurrences could materially and adversely affect our business, financial condition, operating results, cash flows and prospects.

Risks Related to Our Logistics Operations 

Prior  to  our  acquisitions  to  facilitate  our  aircraft  operations,  we  had  no  experience  operating  aircraft  ourselves,  and  we  may  not  be  able  to 

achieve the anticipated benefits of our acquisitions or further expansion of our aircraft operations.

Prior to our acquisitions to facilitate our aircraft operations, we had no experience operating aircraft ourselves, and we depend on the management 
team of Summit and additional employees we may hire for the successful operation of aviation transportation services and the integration into our NOP 
services offering. The management teams must work together to comply with applicable laws and regulations and to manage our growing NOP logistics 
network. The operation of aircraft is a highly regulated activity and one that involves unique risks, including those described above, which we have not 
needed to manage previously. We may not successfully manage these risks or profitably utilize, integrate, operate, maintain and manage our newly acquired 
aircraft, employees and other aircraft operations. 

If we fail to retain the existing management of Summit, or if we fail to successfully manage our aircraft operations or growing logistics network, our 

ability to realize the anticipated benefits of the acquisition of Summit or expansion of our NOP may be adversely affected. 

38

 
The  operation  of  aircraft  is  subject  to  various  risks,  and  failure  to  maintain  an  acceptable  safety  record  may  have  an  adverse  impact  on  our 

ability to obtain and retain customers. 

The operation of aircraft is subject to various risks, including catastrophic disasters, crashes, mechanical failures and collisions, which may result in 
loss of life, personal injury and/or damage to property, plant and equipment. We may experience accidents in the future. These risks could endanger the 
safety  of  our  personnel,  third-parties,  equipment,  viability  of  donor  organs  and  other  property  (both  ours  and  that  of  third-parties),  as  well  as  the 
environment. If any of these events were to occur, we could experience loss of revenue, termination of customer contracts, higher insurance rates, litigation, 
regulatory investigations and enforcement actions (including potential grounding of our fleet and suspension or revocation of our operating authorities) and 
damage to our reputation and customer relationships. In addition, to the extent an accident occurs with an aircraft we operate or charter, we could be held 
liable for resulting damages, which may involve claims from injured passengers, and survivors of deceased passengers and property owners. The amount of 
our  insurance  coverage  may  not  be  adequate  to  cover  such  losses,  or  we  may  be  forced  to  bear  substantial  losses  from  such  events,  regardless  of  our 
insurance coverage. Moreover, any aircraft accident or incident, even if fully insured, and whether involving us or other private aircraft operators, could 
create a public perception that we are less safe or reliable than other private aircraft operators, which could cause our customers to lose confidence in us.  

We incur considerable costs to maintain the quality of (i) our safety program, (ii) our training programs and (iii) our fleet of aircraft. These costs 
may  increase.  If  we  are  unable  to  maintain  an  acceptable  safety  record,  we  may  not  be  able  to  retain  existing  customers  and  employees  or  attract  new 
customers and employees, which could have a material adverse effect on our business, financial condition and results of operations. Failure to comply with 
regulatory  requirements  related  to  the  maintenance  of  our  aircraft  and  associated  operations  may  result  in  enforcement  actions,  including  revocation  or 
suspension of our operating authorities in the United States. 

Significant reliance on aircraft manufactured by a single company and spare parts poses risks to our business and prospects.

As part of our services offered under our NOP, we have acquired a fleet of fixed-wing aircraft. All of the aircraft we currently operate are variants of 
a single model produced by a single manufacturer. Parts and services from this manufacturer are subject to their product and workmanship warranties and 
capacity to service aircraft. If this manufacturer fails to adequately fulfill its obligations towards us or experiences interruptions or disruptions in production 
or provision of services due to, for example, bankruptcy, natural disasters, labor strikes or disruption of its supply chain we may experience a significant 
delay in the delivery of or fail to receive previously ordered parts, which would adversely affect our revenue and results of operations and could jeopardize 
our ability to meet the demands of our customers. Although we could choose to operate aircraft of other manufacturers or increase our reliance on third-
party operators, such a change would involve substantial expense to us and could disrupt our business activities.

We rely on Pratt & Whitney aircraft engines to power our owned aircraft, and we may enter into program agreements covering certain of our aircraft 
related  to  engine  maintenance  and  overhauls  for  certain  aircraft  in  our  fleet.  If  Pratt  &  Whitney  fails  to  adequately  fulfill  its  obligations  towards  us  or 
experiences interruptions or disruptions in production or provision of parts or services due to, for example, bankruptcy, natural disasters, labor strikes or 
disruption  of  its  supply  chain,  we  may  experience  a  significant  delay  in  the  delivery  of  or  fail  to  receive  previously  ordered  aircraft  engines  and  parts, 
which could result in grounded aircraft. These disruptions would adversely affect our revenue and profitability and could jeopardize our ability to meet the 
demands of our customers. In addition, if we fail to meet our obligations or are otherwise in default under the program agreements, our access to aircraft 
engines and parts may become limited, which could adversely impact our business, operations, cash flow, financial condition and liquidity.

The  Federal  Aviation  Administration,  or  FAA,  could  suspend  or  restrict  the  use  of  our  aircraft  in  the  event  of  actual  or  perceived  mechanical 

problems or safety issues while it conducts its own investigation, whether involving our aircraft or another operator’s aircraft. 

39

 
The availability of pilots to the private aviation industries is limited and may negatively affect our operations and financial condition. Increases 

in our labor costs adversely affect our business, results of operations and financial condition. 

Our  pilots  are  subject  to  stringent  pilot  qualification  (including  medical  certification)  and  crew  member  flight  training  standards,  or  FAA 
qualification  standards,  which  among  other  things  require  minimum  flight  hours  for  pilots,  mandate  strict  rules  to  minimize  pilot  fatigue  and  require 
periodic  recertification.  These  requirements  limit  the  availability  of  qualified  pilot  candidates  and  increase  pilot  salaries  and  related  labor  costs,  which 
increases our operating expenses. Such requirements also impact pilot scheduling, work hours and the number of pilots required to be employed for our 
operations. Further, in recent years, the airline industry has experienced significant volatility in pilot attrition, including volatility resulting from pilot wage 
and bonus increases at other industry participants, the growth of air cargo, additional charter operations and airlines, and more pilots reaching retirement 
age. If our attrition rates are higher than our ability to hire and retain replacement pilots, our operations and financial results would be adversely affected.

In  addition,  our  operations  and  financial  condition  may  be  negatively  impacted  if  we  are  unable  to  train  pilots  in  a  timely  manner.  Due  to  an 
industry-wide  shortage  of  qualified  pilots,  driven  by  the  flight  hours  requirements  under  the  FAA  qualification  standards,  including  any  special 
requirements related to certain types of aircraft, and attrition resulting from the hiring needs of other industry participants, pilot training timelines have 
significantly increased and stressed the availability of flight simulators, instructors and related training equipment. The training of our pilots may not be 
accomplished in a cost-efficient manner or in a manner timely enough to support our operational needs.

Due to the nature of our NOP services offering, which may require flight routes to various locations across the United States and often on short 
notice, we may not have access to a qualified pilot at the departure location. We may rely on commercial airlines to fly our pilots to the departure location. 
An inability to have pilots located in departure locations when necessary may cause us to delay or cancel a flight and could adversely affect our reputation, 
business, results of operation and financial condition.

We are exposed to operational disruptions due to maintenance and third-party services.

Our aircraft fleet requires regular maintenance work, which may cause operational disruption. Failure to perform timely maintenance and repairs 
results  in  aircraft  being  underutilized  which  could  have  an  adverse  impact  on  our  business,  financial  condition  and  results  of  operations.  On  occasion, 
airframe  manufacturers  and/or  regulatory  authorities  require  mandatory  or  recommended  modifications  across  a  particular  fleet  which  may  ground  a 
particular type of aircraft. This may cause operational disruption to, and impose significant costs on us. Furthermore, our operations in remote locations, 
where delivery of components and parts or transportation of maintenance personnel could take a significant period of time, could result in delays in our 
ability to maintain and repair our aircraft. Any such delays may pose a risk to our business, financial condition and results of operations. Moreover, as our 
aircraft base increases and our fleet ages, our maintenance costs could potentially increase and we may be unable to manage the composition of our fleet in 
a manner that reduces costs due to the availability and prices for replacement aircraft and parts. 

We  rely  on  third-party  service  providers  to  perform  functions  integral  to  our  operations,  including  ground  handling,  landing  fees,  fueling, 

maintenance, and other services. Disruptions could occur and increase our operating costs or ability to meet customer demands.

Significant increases in aviation fuel costs could have a material adverse effect on our business, financial condition and results of operations.

Fuel is essential to the operation of our aircraft and to our ability to carry out our aircraft operations. Fuel costs are a key component of our operating 
expenses  for  our  aircraft  operations.  A  significant  increase  in  fuel  costs  may  impact  our  flight  activity  and  otherwise  negatively  impact  our  revenue, 
operating  expenses  and  results  of  operations.  In  addition,  potential  increased  environmental  regulations  that  might  require  new  fuel  sources  (e.g., 
sustainable aviation fuel) could lead to increased costs.

40

 
Our insurance may become too difficult or expensive to obtain. If we are unable to maintain sufficient insurance coverage, it may materially and 

adversely impact our results of operations and financial position.

Hazards are inherent in the operation of aircraft and may result in loss of life and property, potentially exposing us to substantial liability claims 
arising from the operation of aircraft. We carry insurance customary for the operation of aircraft. Insurance underwriters are required by various federal and 
state regulations to maintain minimum levels of reserves for known and expected claims. However, underwriters may not have adequate reserves to fund 
existing and future claims. The number of accidents, as well as the number of insured losses within the aviation and aerospace industries, and the impact of 
general  economic  conditions  on  underwriters  may  result  in  increases  in  premiums  above  the  rate  of  inflation.  To  the  extent  that  our  existing  insurance 
carriers  are  unable  or  unwilling  to  provide  us  with  sufficient  insurance  coverage,  and  if  insurance  coverage  is  not  available  from  another  source  (for 
example,  a  government  entity),  our  insurance  costs  may  increase  and  may  result  in  our  being  in  breach  of  regulatory  requirements  or  contractual 
arrangements requiring that specific insurance be maintained, which may have a material adverse effect on our business, financial condition and results of 
operations. 

The  operation  of  aircraft  is  often  affected  by  factors  beyond  our  control  including:  air  traffic  congestion  at  airports;  air  traffic  control 
inefficiencies; increased and changing security measures; changing regulatory and governmental requirements; new or changing travel-related taxes; 
any of which could have a material adverse effect on our business, results of operations and financial condition.

Our aircraft operations are affected by factors beyond our control, including air traffic congestion at airports, air traffic control inefficiencies and 
staffing  shortages,  increased  and  changing  security  measures,  changing  regulatory  and  governmental  requirements,  and  new  or  changing  travel-related 
taxes. Factors that cause flight delays could prevent us from effectively transporting organs in a timely manner, which could have a material adverse effect 
on our business, results of operations and financial condition. 

In the United States, the federal government singularly controls all U.S. airspace, and aviation operators are completely dependent on the FAA to 
operate that airspace in a safe, efficient and affordable manner. The air traffic control system, which is operated by the FAA, in the U.S., faces challenges in 
managing the growing demand for U.S. air travel. U.S. air-traffic controllers often rely on outdated technologies that routinely overwhelm the system and 
compel  aviation  operators  to  fly  inefficient,  indirect  routes  resulting  in  delays  and  increased  operational  cost.  For  example,  in  January  2023,  the  FAA 
experienced an unexpected technical system outage that resulted in all domestic commercial air traffic being temporarily grounded for several hours, which 
adversely  impacted  airlines  and  private  aviation  industry  operators  during  the  duration  of  the  outage.  There  have  also  been  recent  instances  where 
understaffing of certain U.S. air traffic control systems have led to flight delays and cancellations, and resulted in significant costs to aviation operators. 
These instances are capable of repetition and may harm our business and results of operations in the future.

In addition, discussions regarding privatization of the U.S. air traffic control system are ongoing, which could adversely affect our business. Further, 
implementation of the Next Generation Air Transport System by the FAA could result in changes to aircraft routings and flight paths that could lead to 
increased noise complaints and lawsuits, resulting in increased costs. 

Our  aircraft  operations  are  subject  to  significant  governmental  regulation  and  changes  in  government  regulations  imposing  additional 

requirements and restrictions on our aircraft operations could increase our operating costs and result in service delays and disruptions.

All interstate air carriers, including us, are subject to regulation by the DOT, the FAA and other governmental agencies. The laws enforced by these 
agencies impose substantial costs on us, may reduce air travel demand, and also may restrict the manner in which we conduct our business now or in the 
future,  resulting  in  a  material  adverse  effect  on  our  operations.  We  also  incur  substantial  costs  in  maintaining  our  current  certifications  and  otherwise 
complying with the laws and regulations to which we are subject, including airworthiness directives. An adverse decision by a federal agency may have a 
material adverse effect on our operations, such as an FAA decision to ground, or require time consuming inspections of or maintenance on, all or any of our 
aircraft. Our business may also be affected if government agencies shut down for any reason or if there is significant automation or another operational 
disruption, such as those attributed to air traffic control or weather. 

In addition, we are subject to restrictions imposed by federal law on foreign ownership of U.S. airlines and aircraft including oversight by the DOT 
in maintaining our status as a U.S. Citizen (as such term is set forth in Title 49, U.S. Code, Section 40102 and administrative interpretations thereof issued 
by the DOT or its predecessor or successors, or as the same may be from time to time amended). A failure to comply with or changes to these restrictions 
may materially adversely affect our business.

41

 
Revocation of permits, approvals, authorizations and licenses.

Our aircraft operations require a variety of federal, state and local permits, approvals, authorizations and licenses. Our aircraft operations are subject 
to  regulations  and  requirements  and  may  be  adversely  affected  if  we  are  unable  to  comply  with  existing  regulations  or  requirements  or  if  changes  in 
applicable regulations or requirements occur.

Our aircraft maintenance costs will increase as our fleet ages. 

Our aircraft maintenance costs will increase as our fleet ages. Currently, most of the parts on our aircraft are under multi-year warranties, but many 
of these warranties will expire in the coming years. If any maintenance provider with whom we have a flight hour agreement fails to perform or honor such 
agreements,  we  could  incur  higher  interim  maintenance  costs  until  we  negotiate  new  agreements.  Any  unexpected  increase  in  maintenance  costs  may 
negatively impact our financial position and results of operations. 

Our inability to acquire additional aircraft may adversely affect operations.

Additional  aircraft  may  be  needed  to  service  our  customers  and  grow  our  business.  The  inability  to  acquire  sufficient  aircraft  in  the  secondary 
market at acceptable prices could adversely affect our business and could jeopardize our ability to meet the demands of our customers or result in continued 
reliance  on  third-party  charter  operations  that  could  result  in  additional  costs  or  lower  reliability.  Typically,  aircraft  manufacturers  have  a  significant 
backlog of orders resulting in new orders being scheduled more than a year after execution of purchase agreements. Furthermore, manufacturers can face 
production delays due to many factors, including natural disasters, pandemics, supply chain disruptions, labor strikes or availability of skilled labor.

Risks Related to Our Business

Failure  to  maintain  an  ethical  and  inclusive  corporate  culture,  or  damage  to  our  reputation,  could  have  a  material  adverse  effect  on  our 

business. 

We strive to create a culture in which our employees act with integrity, treat each other with respect and consider themselves empowered to report 
suspected misconduct. Our ability to attract and retain a high-quality workforce depends upon our commitment to a diverse and inclusive environment, 
along  with  our  perceived  trustworthiness  and  ethics.  Issues  can  arise  in  any  number  of  circumstances,  including  employment-related  offenses  such  as 
workplace harassment and discrimination, regulatory noncompliance, failure to properly use and protect data and systems, and violations of our employee 
policies,  as  well  as  from  actions  taken  by  regulators  or  others  in  response  to  such  conduct.  Addressing  allegations  of  misconduct  detracts  focus  from 
business operations and is expensive. We have adopted policies to promote compliance with laws and regulations as well as to foster a respectful workplace 
for  all  employees.  These  policies,  which  include  a  code  of  business  conduct  and  ethics,  an  insider  trading  policy,  a  Regulation  FD  policy,  a  sexual
harassment policy, a regulated fraternization policy, and a whistleblower policy, are a component of our effort to minimize employee misconduct as well as 
activities that frequently result in allegations of misconduct. We continuously assess our policies and provide training to our employees, but our employees 
may fail to abide by these policies. In addition to damaging our reputation, actual or alleged misconduct could affect the confidence of our shareholders, 
regulators and other parties and could have a material adverse effect on our business, financial condition and operating results. 

Failure to protect our information technology infrastructure against cyber-based attacks, network security breaches or data corruption could 

materially disrupt our operations and adversely affect our business and operating results. 

The  efficient  operation  of  our  business  depends  on  our  information  technology  systems.  We  rely  on  our  information  technology  systems  to 
effectively manage sales and marketing data, accounting and financial functions, inventory management, product development tasks, clinical data, donor 
and patient data, customer service and technical support functions. However, our information technology systems are vulnerable to damage or interruption, 
including from earthquakes, fires, floods and other natural disasters; terrorist attacks; cyber-based attacks; attacks by computer viruses or hackers; insider 
sabotage;  ransomware;  power  losses,  computer  system  or  data  network  failures;  security  breaches  and  data  corruption.  The  failure  of  either  our  or  our 
service providers’ information technology could disrupt our entire operation or result in decreased sales, increased overhead costs and product shortages, all 
of which could materially and adversely affect our business, financial condition, operating results, reputation, regulatory compliance, litigation exposure, 
cash flows and prospects. In addition, our software systems include cloud-based applications that are hosted by third-party service providers with security 
and information technology systems subject to similar risks, and we may not have accurate or complete information about the risks they face or the security 
of their systems.

42

 
As the cyber-threat landscape evolves, attacks are growing in frequency, sophistication and intensity, are becoming increasingly difficult to detect, 
and  are  being  perpetrated  by  a  broadening  array  of  threat  actors,  including  criminal  hackers,  hacktivists,  nation-states  and  state-sponsored  actors,
perpetrators of industrial espionage and sabotage, and inside threats. New and expanding threats to our information systems, including computer viruses, 
ransomware and phishing attacks, insider attacks, and more sophisticated and targeted cyber-related attacks, as well as cybersecurity failures resulting from 
human error and technological errors, pose a risk to the security of our systems and the systems of our customers, business partners and suppliers, as well
the confidentiality, availability and integrity of the data we process. For example, during the second quarter of 2023, we became aware of an infiltration of 
portions  of  our  information  technology  network.  As  part  of  our  investigation  into  this  incident,  we  engaged  outside  security  experts  and  identified 
unauthorized  theft  of  data  although  no  sensitive  data  were  involved  and  we  do  not  store  patient  related  data  on  our  network  or  anywhere  within  the 
company  premises.  We  have  implemented  additional  security  safeguards  that  we  believe  have  secured  the  system,  however,  these  additional  security 
safeguards may not be successful. While the impact from this incident was not material to the operations of the Company, future impacts from such threats 
may be material. While we maintain insurance coverage for these types of incidents, such policies, may not provide coverage for, or offset the costs of 
responding  to  and  remediating  this  infiltration  or  any  other  such  incidents  or  any  other  liability  that  may  arise  from  this  infiltration  or  any  other  such 
incident.

We  have  access  to  sensitive,  confidential  or  personal  data  or  information  that  is  subject  to  privacy  and  security  laws,  regulations  or  customer-
imposed controls. Despite our implementation of controls designed to protect our systems and sensitive, confidential or personal data or information, we 
have suffered the infiltration described above (and may have suffered other intrusions in the past) and may in the future be vulnerable to material security 
breaches,  theft,  misplaced,  lost  or  corrupted  data,  employee  errors  and/or  malfeasance  (including  misappropriation  by  departing  employees)  that  could 
potentially lead to the compromising of sensitive, confidential or personal data or information.

While we attempt to mitigate these risks by employing a number of measures, including employee training and maintenance of protective systems, 
such measures did not prevent the infiltration described above and may not prove adequate to prevent cyberattacks, and we remain potentially vulnerable to 
additional  known  or  unknown  threats.  The  impact  from  such  threats  could  be  material.  A  significant  cybersecurity  incident  could  result  in  a  range  of 
potentially material negative consequences for us, including lost revenue; unauthorized access to, disclosure, modification, misuse, loss or destruction of 
company systems or data; theft of sensitive, regulated or confidential data, such as personal identifying information or our intellectual property; the loss of 
functionality  of  critical  systems  through  ransomware,  denial  of  service  or  other  attacks;  business  delays,  service  or  system  disruptions,  damage  to 
equipment and injury to persons or property, and increased insurance premiums. The costs and operational consequences of defending against, preparing 
for, responding to and remediating an incident may be substantial. Further, we could be exposed to litigation, regulatory enforcement or other legal action 
as  a  result  of  an  incident,  carrying  the  potential  for  damages,  fines,  sanctions  or  other  penalties,  as  well  injunctive  relief  requiring  costly  compliance 
measures.  Any  cybersecurity  incident  could  also  impact  our  brand,  harm  our  reputation  and  adversely  impact  our  relationship  with  our  customers, 
employees and stockholders.

Economic,  political  and  other  risks  associated  with  foreign  operations  could  adversely  affect  our  international  sales  and  our  results  of 

operations. 

Because we market the OCS in countries in Europe, Asia-Pacific, Central Asia and Canada and plan to market it in other international markets, we 
are  subject  to  risks  associated  with  doing  business  internationally.  During  the  years  ended  December  31,  2023,  2022  and  2021,  6%,  10%  and  28%, 
respectively,  of  our  revenue  was  generated  from  customers  located  outside  of  the  United  States.  We  anticipate  that  international  sales  will  continue  to 
represent a portion of our total sales. In addition, some of our employees and suppliers are located outside of the United States. Accordingly, our results of 
operations could be harmed by a variety of factors, including: 

•

•

•

•

•

•

changes in a country’s or region’s political or economic conditions;

longer payment cycles of foreign customers and difficulty of collecting receivables in foreign jurisdictions;

different or changing regulatory or insurance practices regarding reimbursement for transplant procedures;

difficulties in developing effective marketing campaigns in unfamiliar foreign countries;

trade protection measures, import or export licensing requirements or customs clearance and shipping delays;

fluctuations in foreign currency exchange rates;

43

 
•

•

•

•

•

•

•

•

differing tax laws and changes in those laws in the countries in which we are subject to tax, or potentially adverse tax consequences, including 
the complexities of foreign value-added tax systems, tax inefficiencies related to our corporate structure, and restrictions on the repatriation of 
earnings;

changes  in  international  legislation  or  regulations  governing  the  approval  or  clearance  process  for  the  OCS  or  ongoing  compliance 
requirements;

differing business practices associated with foreign operations;

difficulties in staffing and managing our international operations;

political, social, and economic instability abroad, terrorist attacks, and security concerns in general;

the burdens of complying with a wide variety of foreign laws and different legal standards, such as anti-bribery laws, including the FCPA, and 
UK Bribery Act of 2010, or the Bribery Act, data privacy requirements, labor laws and anti-competition regulations;

differing protection of intellectual property; and

increased financial accounting and reporting burdens and complexities.

We  rely  on  shipping  providers  to  deliver  products  to  our  customers  globally.  Labor,  tariff  or  World  Trade  Organization-related  disputes,  piracy, 
physical damage to shipping facilities or equipment caused by severe weather or terrorist incidents, congestion at shipping facilities, inadequate equipment 
to load, dock and offload our products, energy-related tie-ups or other factors could disrupt or delay shipping or off-loading of our products domestically 
and  internationally.  Such  disruptions  or  delays  could  materially  and  adversely  affect  our  business,  financial  condition,  operating  results,  cash  flows  and 
prospects. 

If  one  or  more  of  these  risks  are  realized,  our  business,  financial  condition,  operating  results,  cash  flows  and  prospects  could  be  materially  and 

adversely affected. 

Our success depends on our ability to retain our founder and President and Chief Executive Officer and other members of our management 

team and to attract, retain and motivate qualified personnel. 

Our success depends on our continued ability to attract, retain and motivate highly qualified clinicians, surgeons, scientists, engineers, managers and 
sales  personnel.  Dr.  Waleed  H.  Hassanein,  our  founder  and  President  and  Chief  Executive  Officer,  and  other  members  of  our  management  team  are 
important to the success of our operations. All of these key employees, including Dr. Hassanein, are at-will employees and can terminate their employment 
with us at any time. The loss of any of these key members of our management team and, in particular, Dr. Hassanein, could impede our achievement of our 
research, development and commercialization objectives. We maintain a “key person” insurance policy on the life of Dr. Hassanein, but we do not maintain 
such insurance on any of our other employees. 

In addition, our expected growth will require us to hire a significant number of qualified personnel, including clinical development, regulatory, sales, 
marketing, engineering, scientific, clinical, logistics and aviation support and administrative personnel. There is intense competition from other companies 
and research and academic institutions for qualified personnel in the areas of our activities. If we cannot continue to attract and retain, on acceptable terms, 
the qualified personnel necessary for the continued development of our business, we might not be able to sustain our operations or become profitable. 

44

 
The failure to manage our growth effectively could harm our business. 

To  manage  our  anticipated  future  growth  effectively,  we  must  enhance  our  manufacturing  and  sterilization  capabilities,  information  technology 
infrastructure  and  financial  and  accounting  systems  and  controls.  Our  growth  will  require  significant  capital  expenditures  and  may  divert  financial 
resources from other projects, such as the development of the OCS for transplants involving additional indications or other organs. Our NOP, an innovative 
turnkey solution to provide outsourced organ retrieval, OCS organ management and logistics services, will also require additional capital expenditures. If 
we are unable to effectively manage our growth, our expenses may increase more than expected, our revenue could grow more slowly than expected and 
we  might  not  be  able  to  achieve  our  research  and  development  and  commercialization  goals,  which  in  turn  could  materially  and  adversely  affect  our 
business, financial condition, operating results, cash flows and prospects. 

Risks Related to Our Intellectual Property 

If we infringe or are alleged to infringe the intellectual property rights of third parties or are otherwise subject to litigation or other proceedings 

regarding our intellectual property rights, our business or competitive position could be adversely affected. 

Our commercial success will depend in part on not infringing, misappropriating or otherwise violating the patents or other intellectual property or 
proprietary rights of others. Significant litigation regarding patent and other intellectual property rights occurs in the medical device industry. Third parties 
may claim that the OCS or aspects or uses of the OCS infringe intellectual property rights for which we do not hold licenses or other rights in the United 
States and abroad. Third parties in both the United States and abroad may have applied for or obtained, or may in the future apply for and obtain, patents 
that will prevent, limit or otherwise interfere with our ability to make, use and sell our products. 

Given the vast number of patents in our field of technology, we cannot be certain that we do not infringe existing patents or that we will not infringe 
patents  that  may  be  granted  in  the  future.  For  example,  patent  applications  in  the  United  States  and  elsewhere  can  be  pending  for  many  years  before 
issuance,  or  unintentionally  abandoned  patents  or  applications  can  be  revived,  so  there  may  be  applications  of  others  now  pending  or  recently  revived 
patents of which we are unaware. These applications may later result in issued patents, or the revival of previously abandoned patents, that will prevent, 
limit or otherwise interfere with our ability to make, use or sell our products. Third parties may, in the future, assert claims that we are employing their 
proprietary technology without authorization, including claims from competitors or from non-practicing entities that have no relevant product revenue and 
against  whom  our  own  patent  portfolio  may  have  no  deterrent  effect.  As  we  continue  to  commercialize  our  products  in  their  current  or  updated  forms, 
launch new products and enter new markets, competitors may claim that one or more of our products infringe their intellectual property rights as part of 
business strategies designed to impede our successful commercialization and entry into new markets. The large number of patents, the rapid rate of new 
patent applications and issuances, the complexities of the technology involved, and the uncertainty of litigation may increase the risk of business resources
and management’s attention being diverted to patent litigation. 

If any third-party patents were asserted against us, even if we believe such claims are without merit, there is no assurance that a court would find in 
our favor on questions of infringement, validity, enforceability, or priority. A court of competent jurisdiction could hold that the asserted third-party patents 
are  valid,  enforceable,  and  infringed,  which  could  materially  and  adversely  affect  our  ability  to  commercialize  our  products.  In  order  to  successfully 
challenge the validity of any U.S. patent in federal court, we would need to overcome a presumption of validity. As this burden is a high one requiring us to 
present clear and convincing evidence as to the invalidity of any such U.S. patent claim, there is no assurance that a court of competent jurisdiction would 
invalidate  the  claims  of  any  such  U.S.  patent.  We  may  choose  or,  if  we  are  found  to  infringe  a  third  party’s  patent  rights  and  we  are  unsuccessful  in 
demonstrating  that  such  patents  are  invalid  or  unenforceable,  we  could  be  required  to  obtain  a  license  from  such  third  party  to  continue  developing, 
manufacturing, and marketing any of our products. However, we may not be able to obtain any required license on commercially reasonable terms or at all. 
Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access to the same technologies 
licensed  to  us,  and  it  could  require  us  to  make  substantial  licensing  and  royalty  payments.  We  also  could  be  forced,  including  by  court  order,  to  cease 
developing,  manufacturing,  and  commercializing  the  infringing  technology  or  products.  In  addition,  we  could  be  found  liable  for  significant  monetary 
damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent or other intellectual property right. There could 
also be public announcements of the results of hearing, motions, or other interim developments. If securities analysts or investors perceive these results to 
be  negative,  it  could  have  a  material  adverse  effect  on  the  price  of  shares  of  our  common  stock.  Claims  that  we  have  misappropriated  the  confidential 
information  or  trade  secrets  of  third  parties  could  have  a  similar  material  adverse  effect  on  our  business,  financial  condition,  results  of  operations  and 
prospects. 

45

 
Our industry has experienced substantial litigation and other proceedings regarding patent and other intellectual property rights and lawsuits to 

protect or enforce our patents and other intellectual property rights could be expensive, time-consuming and unsuccessful. 

In addition to infringement claims against us, we may become a party to other types of patent litigation and other proceedings, including post-grant 
proceedings declared by the United States Patent and Trademark Office, or USPTO, and opposition proceedings in the European Patent Office, regarding 
intellectual property rights with respect to the OCS. For example, we may be subject to a third-party preissuance submission of prior art to the USPTO, or 
become involved in post-grant review procedures, oppositions, derivations, reexaminations, inter partes review or interference proceedings, in the United 
States  or  elsewhere,  challenging  our  patent  rights  or  the  patent  rights  of  others.  An  adverse  determination  in  any  such  challenges  may  result  in  loss  of 
exclusivity or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from 
using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and products. The 
cost to us of any patent litigation or other proceeding, even if resolved in our favor, could be substantial. Some of our competitors may be able to sustain 
the  costs  of  such  litigation  or  proceedings  more  effectively  than  we  can  because  of  their  greater  financial  resources.  Uncertainties  resulting  from  the 
initiation  and  continuation  of  patent  litigation  or  other  proceedings  could  have  a  material  adverse  effect  on  our  ability  to  compete.  Patent  litigation  and 
other proceedings may also absorb significant management time. 

In addition, competitors and other third parties may infringe, misappropriate or otherwise violate our patents and other intellectual property rights. 
To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming and divert the 
time  and  attention  of  our  management.  In  addition,  many  of  our  adversaries  in  these  proceedings  may  have  the  ability  to  dedicate  substantially  greater 
resources to prosecuting these legal actions than we can. 

A court may disagree with our allegations and may refuse to stop the other party from using the technology at issue on the grounds that our patents 
do  not  cover  the  third-party  technology  in  question.  Furthermore,  the  other  party  could  counterclaim  that  we  infringe  their  intellectual  property  or 
counterclaim  that  a  patent  we  have  asserted  against  them  is  invalid  or  unenforceable,  or  both.  In  patent  litigation  in  the  United  States,  counterclaims 
challenging  the  validity,  enforceability  or  scope  of  asserted  patents  are  commonplace.  Similarly,  third  parties  may  initiate  legal  proceedings  against  us 
seeking a declaration that certain of our intellectual property rights are non-infringed, invalid, or unenforceable. The outcome of any such proceeding is 
generally unpredictable. 

An adverse result in any litigation proceeding could put one or more of our patents at risk of being invalidated or interpreted narrowly. If a defendant 
were to prevail on a legal assertion of invalidity or unenforceability of our patents covering one of our products, we would lose at least part, and perhaps 
all, of the patent protection covering such product. Competing products may also be sold in other countries in which our patent coverage might not exist or 
be as strong. Any of these outcomes would have a material adverse effect on our business. 

Because  of  the  substantial  amount  of  discovery  required  in  connection  with  intellectual  property  litigation,  there  is  a  risk  that  some  of  our 
confidential  information  could  be  compromised  by  disclosure  during  litigation.  There  could  also  be  public  announcements  of  the  results  of  hearing, 
motions, or other interim developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on 
the price of shares of our common stock. Even if we ultimately prevail, a court may decide not to grant an injunction against further infringing activity and 
instead award only monetary damages, which may not be an adequate remedy. Furthermore, the monetary cost of such litigation and the diversion of the 
attention  of  our  management  could  outweigh  any  benefit  we  receive  as  a  result  of  the  proceedings.  Uncertainties  resulting  from  the  initiation  and 
continuation of patent litigation or other proceedings could have a material adverse effect on our business. 

If we are unable to establish, maintain or adequately protect our intellectual property rights relating to the OCS, the commercial value of the 

OCS will be adversely affected and our competitive position could be harmed. 

Our success and ability to compete depend in part upon our ability to establish and maintain intellectual property rights covering the OCS in the
United States and other countries. We own several patents and patent applications in the United States and corresponding patents and patent applications in 
a number of foreign jurisdictions. With respect to the patents and patent applications that we own, any patents that have or may issue from our currently 
issued or pending patent applications would be expected to expire between 2025 and 2043, assuming all required fees are paid.

46

 
However,  we  cannot  provide  any  assurances  that  any  of  our  patents  have,  or  that  any  of  our  pending  patent  applications  that  mature  into  issued 
patents will include, claims with a scope sufficient to protect our OCS technology, any additional features we develop for our OCS technology or any new 
products.  Other  parties  may  have  developed  technologies  that  may  be  related  to  or  competitive  with  our  system,  may  have  filed  or  may  file  patent 
applications and may have received or may receive patents that overlap or conflict with our patent applications, either by claiming the same methods or 
devices  or  by  claiming  subject  matter  that  could  dominate  our  patent  position.  The  patent  positions  of  medical  device  companies,  including  our  patent 
position, may involve complex legal and factual questions, and, therefore, the scope, validity and enforceability of any patent claims that we may obtain 
cannot be predicted with certainty. Our pending and future patent applications may not issue as patents or, if issued, may not issue in a form that will be 
advantageous to us. Even if issued, our patents may be challenged, narrowed, held unenforceable, invalidated or circumvented, or others could challenge 
the inventorship, ownership or enforceability of our patents and patent applications, any of which could limit our ability to stop competitors from marketing 
similar products or limit the term of patent protection we may have for our products, or cause us to lose our right to manufacture, market and sell the OCS 
products  or  components  of  the  OCS  products.  Additionally,  the  Leahy-Smith  America  Invents  Act,  or  the  Leahy-Smith  Act,  includes  a  number  of 
significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted, redefine prior art, and provide more 
efficient and cost-effective avenues for competitors to challenge the validity of patents. In addition, the Leahy-Smith Act has transformed the U.S. patent 
system into a first-to-file system. The first-to-file provisions became effective on March 16, 2013. It is not clear what, if any, impact the Leahy-Smith Act 
will  have  on  the  operation  of  our  business.  For  example,  the  Leahy-Smith  Act  provides  that  an  administrative  tribunal  known  as  the  Patent  Trial  and 
Appeals Board, or PTAB, provides a venue for challenging the validity of patents at a cost that is much lower than district court litigation and on timelines 
that are much faster. Proceedings challenging our patents could result in either loss of the patent or denial of the patent application or loss or reduction in 
the scope of one or more of the claims of the patent or patent application. Furthermore, an adverse decision in an interference proceeding can result in a 
third party receiving the patent right sought by us, which in turn could affect our ability to commercialize our products. 

Changes in either patent laws or in interpretations of patent laws in the United States and other countries may diminish the value of our intellectual 
property or narrow the scope of our patent protection, which in turn could diminish the commercial value of the OCS. The laws of some foreign countries 
do  not  protect  our  proprietary  rights  to  the  same  extent  as  the  laws  of  the  United  States,  and  we  may  encounter  significant  problems  in  protecting  our 
proprietary rights in these countries. 

The degree of future protection for our proprietary rights is uncertain, and we cannot ensure that: 

•

•

•

•

•

•

•

•

•

any of our patents, or any of our pending patent applications, if issued, will include claims having a scope sufficient to protect the OCS;

any of our pending patent applications will issue as patents;

we will be able to successfully commercialize our products on a substantial scale, if approved, before any relevant patents we may have expire;

we were the first to make the inventions covered by each of our patents and pending patent applications;

we were the first to file patent applications for these inventions;

others will not develop similar or alternative technologies that do not infringe our patents; any of our patents will be found to ultimately be 
valid and enforceable;

any patents issued to us will provide a basis for an exclusive market for our commercially viable products, will provide us with any competitive 
advantages or will not be challenged by third parties;

we will develop additional proprietary technologies or products that are separately patentable; or

our commercial activities or products will not infringe upon the patents of others.

47

 
If we are unable to obtain patent term extension under the Hatch-Waxman Act, our business may be materially harmed. 

Depending upon the timing, duration and specifics of FDA marketing approval of our products, one or more of the U.S. patents we own or license 
may be eligible for limited patent term restoration under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-
Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years for a patent covering an approved product as compensation for 
effective patent term lost during product development and the FDA regulatory review process. However, even if, at the relevant time, we have an issued 
patent  covering  our  product,  we  may  not  be  granted  an  extension  if  we  were,  for  example,  to  fail  to  exercise  due  diligence  during  the  testing  phase  or 
regulatory review process, to fail to apply within applicable deadlines or prior to expiration of relevant patents or otherwise to fail to satisfy applicable 
requirements. Moreover, the time period of the extension or the scope of patent protection afforded could be less than we request. Only one patent per 
approved product can be extended, the extension cannot extend the total patent term beyond 14 years from approval and only those claims covering the 
approved product, a method for using it or a method for manufacturing it may be extended. If we are unable to obtain patent term extension or restoration 
or  the  term  of  any  such  extension  is  less  than  we  request,  the  period  during  which  we  can  enforce  our  patent  rights  for  the  applicable  product  will  be 
shortened  and  our  competitors  may  obtain  approval  of  competing  products  following  our  patent  expiration.  As  a  result,  our  ability  to  generate  revenue 
could  be  materially  adversely  affected.  Further,  if  this  occurs,  our  competitors  may  take  advantage  of  our  investment  in  development  and  trials  by 
referencing our clinical and preclinical data and launch their product earlier than might otherwise be the case. If we do not have adequate patent protection 
or other exclusivity for our products, our business, financial condition or results of operations could be materially adversely affected. 

We may be unable to enforce our intellectual property rights throughout the world. 

The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the United States. Many companies 
have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. This could make it difficult 
for us to stop infringement of our foreign patents, if obtained, or the misappropriation of our other intellectual property rights. For example, some foreign 
countries  have  compulsory  licensing  laws  under  which  a  patent  owner  must  grant  licenses  to  third  parties.  In  addition,  some  countries  limit  the 
enforceability of patents against third parties, including government agencies or government contractors. In these countries, patents may provide limited or 
no benefit. Patent protection must ultimately be sought on a country-by-country basis, which is an expensive and time-consuming process with uncertain 
outcomes.  Accordingly,  we  may  choose  not  to  seek  patent  protection  in  certain  countries,  and  we  will  not  have  the  benefit  of  patent  protection  in  such 
countries. 

Proceedings  to  enforce  our  patent  rights  in  foreign  jurisdictions  could  result  in  substantial  costs  and  divert  our  efforts  and  attention  from  other 
aspects of our business. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate. In addition, changes in the 
law and legal decisions by courts in the United States and foreign countries may affect our ability to obtain adequate protection for our technology and the 
enforcement of our intellectual property. 

If  we  are  unable  to  protect  the  confidentiality  of  our  trade  secrets,  the  value  of  the  OCS  and  our  business  and  competitive  position  could  be 

harmed. 

In  addition  to  patent  protection,  we  also  rely  upon  trade  secret  protection,  as  well  as  non-disclosure  agreements  and  invention  assignment 
agreements with our employees, consultants and third parties, to protect our confidential and proprietary information. In addition to contractual measures, 
we  try  to  protect  the  confidential  nature  of  our  proprietary  information  using  commonly  accepted  physical  and  technological  security  measures.  Such 
measures may not, for example, in the case of misappropriation of a trade secret by an employee or third party with authorized access, provide adequate 
protection for our proprietary information. Our security measures may not prevent an employee or consultant from misappropriating our trade secrets and 
providing  them  to  a  competitor,  and  recourse  we  take  against  such  misconduct  may  not  provide  an  adequate  remedy  to  protect  our  interests  fully. 
Unauthorized parties may also attempt to copy or reverse engineer certain aspects of our products that we consider proprietary. Enforcing a claim that a 
party illegally disclosed or misappropriated a trade secret can be difficult, expensive and time-consuming, and the outcome is unpredictable. Even though 
we use commonly accepted security measures, trade secret violations are often a matter of state law, and the criteria for protection of trade secrets can vary 
among different jurisdictions. In addition, trade secrets may be independently developed by others in a manner that could prevent legal recourse by us. We 
also have agreements with our employees, consultants and third parties that obligate them to assign inventions made in the course of their work for us to us, 
however these agreements may not be self-executing, not all employees or consultants may enter into such agreements, or employees or consultants may 
breach or violate the terms of these agreements, and we may not have adequate remedies for any such breach or violation. If any of our intellectual property 
or confidential or proprietary information, such as our trade secrets, were to be disclosed or misappropriated, or if any such information was independently 
developed by a competitor, the value of the OCS and our business and competitive position could be harmed. 

48

 
We may be subject to claims that we or our employees have misappropriated the intellectual property of a third party, including trade secrets or 
know-how, or are in breach of non-competition or non-solicitation agreements with our competitors and third parties may claim an ownership interest 
in intellectual property we regard as our own. 

Many  of  our  employees  and  consultants  were  previously  employed  at  or  engaged  by  other  medical  device,  biotechnology  or  pharmaceutical 
companies, including our competitors or potential competitors, hospitals or other third parties. Some of these employees, consultants and contractors may 
have executed proprietary rights, non-disclosure and non-competition agreements in connection with such previous employment. Although we try to ensure 
that our employees and consultants do not use the intellectual property, proprietary information, know-how or trade secrets of others in their work for us, 
we may be subject to claims that we or these individuals have, inadvertently or otherwise, misappropriated the intellectual property or disclosed the alleged 
trade secrets or other proprietary information, of these former employers, competitors or other third parties. Additionally, we may be subject to claims from 
third parties challenging our ownership interest in or inventorship of intellectual property we regard as our own, based on claims that our agreements with 
employees or consultants obligating them to assign intellectual property to us are ineffective or in conflict with prior or competing contractual obligations 
to assign inventions to another employer, to a former employer, or to another person or entity. Litigation may be necessary to defend against claims, and it 
may be necessary or we may desire to enter into a license to settle any such claim; however, there can be no assurance that we would be able to obtain a 
license on commercially reasonable terms, if at all. If our defense to those claims fails, in addition to paying monetary damages or a settlement payment, a 
court could prohibit us from using technologies, features or other intellectual property that are essential to our products, if such technologies or features are 
found to incorporate or be derived from the trade secrets or other proprietary information of the former employers. An inability to incorporate technologies, 
features or other intellectual property that are important or essential to our products could have a material adverse effect on our business and competitive 
position,  and  may  prevent  us  from  selling  our  products.  In  addition,  we  may  lose  valuable  intellectual  property  rights  or  personnel.  Even  if  we  are 
successful  in  defending  against  these  claims,  litigation  could  result  in  substantial  costs  and  could  be  a  distraction  to  management.  Any  litigation  or  the 
threat thereof may adversely affect our ability to hire employees or contract with independent sales representatives. A loss of key personnel or their work 
product could hamper or prevent our ability to commercialize our products, which could materially and adversely affect our business, financial condition, 
operating results, cash flows and prospects. 

Risks Related to Government Regulation 

Even after approval for the OCS, we are subject to continuing regulation by regulatory authorities and entities in the United States and other 

countries, and if we fail to comply with any of these regulations, our business could suffer. 

Even  after  approval  of  the  OCS  for  a  specific  indication,  we  are  subject  to  extensive  continuing  regulation  by  the  FDA  and  other  regulatory 
authorities and entities. We are subject to Medical Device Reporting regulations, which require us to report to the FDA if we become aware of information
that reasonably suggests our product may have caused or contributed to a death or serious injury, or has malfunctioned and the device or a similar device 
we market would likely cause or contribute to a death or serious injury if the malfunction were to recur. We must report corrections and removals to the 
FDA where the correction or removal was initiated to reduce a risk to health posed by the device or to remedy a violation of the FDCA caused by the 
device that may present a risk to health, and maintain records of other corrections or removals. The FDA closely regulates promotion and advertising and 
all claims that we make for the OCS. If the FDA determines that our promotional materials, training or advertising activities constitute promotion of an 
unapproved use of the OCS, it could request that we cease or modify our training or promotional materials or subject us to regulatory enforcement actions. 

The  FDA  and  state  authorities  have  broad  enforcement  powers.  Our  failure  to  comply  with  applicable  regulatory  requirements  could  result  in 

enforcement actions by the FDA or state agencies, which may include any of the following sanctions: 

•

•

•

•

•

untitled letters, warning letters, fines, injunctions, consent decrees and civil penalties;

recall, suspension or termination of distribution, administrative detention, injunction or seizure of organ-specific OCS Consoles or disposable 
sets;

customer notifications or repair, replacement or refunds;

operating restrictions or partial suspension or total shutdown of production;

refusing or delaying our requests for premarket approval of new products or for modifications to existing products, and refusing or delaying 
our requests for PMAs for new intended uses of the OCS;

49

 
•

•

•

withdrawing or suspending PMA approvals that have already been granted, resulting in prohibitions on sales of our products;

FDA refusal to issue certificates to foreign governments needed to export products for sale in other countries; and

criminal prosecution.

Any corrective action, whether voluntary or involuntary, as well as potentially defending ourselves in a lawsuit, will require the dedication of our 

time and capital, distract management from operating our business, and may harm our reputation and financial results. 

For our currently marketed OCS Lung, OCS Heart and OCS Liver, as part of the conditions of approval, we must complete PMA post-approval 
studies. For example, the OCS Lung TOP Registry must be completed, which is a prospective, single-arm, multi-center, observational study designed to 
evaluate short- and long-term safety and effectiveness of the OCS Lung for both donor lungs currently utilized and unutilized for transplantation. Our TOP
Registry entails submission of regular reports to the FDA. Failure to comply with the conditions of approval can result in material adverse action, including 
withdrawal of the approval.

We  also  are  required  to  comply  with  strict  post-marketing  obligations  that  accompany  the  affixing  of  the  CE  Mark  to  medical  devices  in  the 
European Union. These include the obligation to report incidents which meet the criteria for reporting, and to provide periodic safety update reports and 
trend  reports.  Additionally,  national  competent  authorities  in  the  European  Union  also  closely  monitor  the  marketing  programs  implemented  by  device 
companies.  The  obligations  that  companies  must  fulfill  concerning  premarketing  approval  of  promotional  material  vary  among  member  states  of  the 
European Union. A failure to comply with our obligations in marketing and promoting the OCS in the European Union could harm our business and results 
of operations.

In addition, certain changes and other events with respect to regulatory approvals may cause an event of default under our CIBC Credit Agreement. 

See “Item 7. Management’s Discussion and Analysis - Long-Term Debt,” in this Annual Report on Form 10-K. 

Our products have been and may in the future be subject to product recalls that could harm our reputation and could materially and adversely 

affect our business, financial condition, operating results, cash flows and prospects.

The OCS must be manufactured in accordance with federal and state regulations, and we or any of our suppliers or third-party manufacturers could 
be  forced  to  recall  our  installed  systems  or  suspend  or  terminate  production  if  we  fail  to  comply  with  these  regulations.  The  FDA  and  similar  foreign 
governmental  authorities  have  the  authority  to  require  the  recall  of  commercialized  products  in  the  event  of  material  deficiencies  or  defects  in  design, 
manufacture or labeling. In the case of the FDA, the recall order must be based on an FDA finding that there is a reasonable probability that the device 
would cause serious adverse health consequences or death. In addition, foreign governmental bodies have the authority to require the recall of our products 
in the event of material deficiencies or defects in design or manufacture. Manufacturers may, under their own initiative, recall a product if any material 
deficiency  in  a  device  is  found.  A  government-mandated  or  voluntary  recall  by  us  could  occur  as  a  result  of  component  failures,  security  failures, 
manufacturing  errors,  design  or  labeling  defects  or  other  deficiencies  and  issues.  Recalls  of  any  of  our  products  would  divert  managerial  and  financial 
resources and have an adverse effect on our financial condition and results of operations. The FDA requires that recalls initiated to reduce a risk to health 
posed by the device or to remedy a violation of the FDCA caused by the device that may present a risk to health be reported to the FDA within 10 working 
days after the recall is initiated. Companies are required to maintain records of recalls, even if they are not reportable to the FDA. We may initiate voluntary
recalls involving our products in the future that we determine do not require notification of the FDA. If the FDA disagrees with our determinations, we 
could  be  required  to  report  those  actions  as  recalls.  A  recall  announcement  could  harm  our  reputation  with  customers  and  negatively  affect  our  sales. 
Additionally, any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will require the dedication of our time 
and  capital,  distract  management  from  operating  our  business  and  may  harm  our  reputation  and  financial  results.  In  addition,  the  FDA  could  take 
enforcement action for failing to report the recalls when they were conducted, including warning letters, untitled letters, administrative actions, criminal 
prosecution, imposition of civil monetary penalties, seizure of our products or delay in clearance or approval of future products.

50

 
We have voluntarily recalled certain OCS products from clinical sites in the past and may need to take similar actions in the future, which may result 
in  notices  to  regulatory  agencies  in  other  jurisdictions.  As  we  continue  to  expand  commercialization  of  our  products  and  sell  OCS  products  to  new 
customers, the impact of any future product recall increases, and any future product recalls would require greater administrative and response efforts than
historical product recalls.

Internationally,  the  approaches  to  product  defects  will  vary.  A  product  may  be  recalled  in  one  country  but  not  in  others.  However,  within  the 
European Union, competent authorities are required without delay to take corrective action against a device (including withdrawal/recall of a device) and 
notify other national competent authorities, the European Commission and notified bodies (as applicable) of any devices that present an unacceptable risk 
to the health or safety of patients, users or other persons, or other aspects of the protection of public health. Other non-compliance with the MDR may also 
lead to corrective action being taken and notifications being sent if the non-compliance is not rectified within a given time period (as determined by the 
competent authority). Therefore, a recall in one EU member state may lead to recalls in the rest of the European Union.

If we fail to maintain necessary FDA approvals for the OCS, or obtain necessary FDA approval for future uses of the OCS, we will not be able 

to commercially sell and market the OCS. 

The OCS products are medical devices subject to extensive regulation in the United States by the FDA and other federal, state and local authorities. 
The  FDA  regulates  the  design,  development,  testing,  manufacturing,  labeling,  selling,  promoting,  distributing,  importing,  exporting  and  shipping  of  the 
OCS. We have obtained a PMA for each of the OCS Lung, OCS Liver and OCS Heart for both DBD and DCD indications. We received 510(k) clearances 
for the OCS Lung Solution for cold flush, storage and transportation of donor lungs in July 2021, for the OCS Lung Donor Flush Set in November 2022, 
and for the OCS Heart Leukocyte Reducing Filter in October 2023. 

PMA approval could be withdrawn or other restrictions imposed if post- market data demonstrate safety issues or inadequate performance. The FDA 

can also require removal of 510(k) cleared devices from the market in case of safety issues.

If we are not able to maintain the necessary regulatory approvals for the OCS, or obtain the necessary regulatory approvals or clearances for future 

products on a timely basis or at all, our financial condition and results of operations would suffer, possibly materially, and our business might fail. 

If we fail to maintain the CE Mark in the European Union, Northern Ireland and the UKCA mark (as applicable) in Great Britain, we will not 

be able to commercially sell and market the OCS in the EU or UK.

In the European Union, we have the right to affix a CE Mark for the sale of the OCS Lung, OCS Heart and OCS Liver for lung, heart and liver 
transplants, respectively. Our notified body, BSI, is based in the Netherlands and issues the certificates that allow CE marking of the OCS products. Our 
sales  in  the  EU  are  dependent  on  obtaining  and  maintaining  the  CE  Mark  certifications  for  each  of  our  OCS  products.  As  required  by  the  MDR,  we 
received recertification of the CE Mark in September 2022 for each of the OCS Heart and OCS Lung systems, which includes the OCS Console, the OCS 
disposables,  and  the  OCS  solution  additives.  We  also  received  the  recertification  of  the  CE  Mark  in  September  2022  for  the  OCS  Liver  Console  and 
disposables. We received the CE Mark for the OCS Liver combined with our solution additives under the MDR in May 2023, with an effective date of 
April 2023. In order to be able to continue to use the CE Mark we will have to meet the conditions set out in the MDR.

Post-Brexit the MDR applies in Northern Ireland in accordance with the Northern Ireland Protocol but does not apply in Great Britain (England, 
Wales and Scotland). The UK Medical Devices Regulations 2002 (UK MDR 2002) provided a transitional period under which the UK will recognize EU 
CE  marks  and  the  MHRA  has  confirmed  that  this  will  be  extended  potentially  until  June  30,  2030  (subject  to  certain  conditions).  To  be  placed  on  the 
market in Great Britain after this date, medical devices must have undergone a conformity assessment in accordance with the UK MDR 2002 and have the 
UKCA mark affixed. However, even devices that benefit from the transition period must still comply with the other requirements of the UK MDR 2002; 
for  example,  there  are  broader  registration  requirements  with  the  Medicines  and  Healthcare  products  Regulatory  Agency,  or  the  MHRA,  and  if  the 
manufacturer is located outside the UK, a UK Responsible Person must be appointed.

To continue to place products on the market in the European Union and United Kingdom, we will need to meet the conditions set out in the EU 
MDR or UK MDR 2002, as applicable. We might not be able to continue to place the devices on the market in the European Union and/or United Kingdom 
for any current use of the OCS if we are not able to maintain certifications of our products for their current use under the MDR and/or obtain certification 
under the UK MDR 2002 when required. If any variation in the uses for which the CE/UKCA mark has been affixed to the OCS requires us to perform 
further  research  or  to  modify  the  technical  documentation  required  to  affix  the  CE/UKCA  mark,  our  revenue  and  operating  results  could  be  adversely 
affected and our reputation could be harmed.

51

 
If we fail to obtain and maintain regulatory approval in foreign jurisdictions, our market opportunities will be limited. 

FDA  clearance  or  approval  or  a  CE  mark  does  not  ensure  approval  by  regulatory  authorities  in  other  countries,  and  approval  by  one  foreign 
regulatory authority does not ensure approval by regulatory authorities in other foreign countries. However, the failure to obtain clearance or approval in 
one jurisdiction may have a negative impact on our ability to obtain clearance or approval elsewhere. If we do not obtain or maintain necessary market 
authorizations to commercialize our products in markets outside the United States, it would negatively affect our overall market penetration. For example, 
if, as a result of manufacturing error, the efficacy of our products does not meet the standards claimed in the accompanying instructions for use, regulatory 
authorities could prevent our products from being placed on the market in the European Union, Northern Ireland, Great Britain and elsewhere. 

If transplant centers and hospitals cannot obtain adequate reimbursement or funding from governments or third-party payors for purchases of 
the OCS and additional disposable sets and for costs associated with procedures that use the OCS and the NOP, our prospects for generating revenue 
and achieving profitability will suffer materially. 

Our prospects for generating revenue and achieving profitability depend heavily upon the availability of adequate reimbursement or funding in both 

the United States and other markets for purchases of the OCS and for organ transplant procedures that use the OCS and the NOP. 

In the United States, Medicare generally reimburses the facilities in which transplant procedures are performed based upon prospectively determined 
amounts. For hospital inpatient treatment, the Medicare prospective payment generally is determined by the patient’s condition and other patient data and 
procedures performed during the patient’s hospital stay, using a classification system known as MS-DRGs. Prospective rates are adjusted for, among other 
things, regional differences and whether the hospital is a teaching hospital. Because prospective payments are based on predetermined rates and may be less 
than a hospital’s actual costs in furnishing care, hospitals have incentives to lower their inpatient operating costs by utilizing products, devices and supplies 
that will reduce the length of patients’ hospital stays, decrease labor or otherwise lower their costs.

In  addition  to  these  MS-DRG-based  payments,  Medicare  reimburses  transplant  centers  for  “reasonable  and  necessary”  organ  acquisition  costs, 
which are considered “pass-through” costs from the prospective payment system, and are not based on the payments for the applicable MS-DRG. Pass-
through  organ  acquisition  costs  include  services  required  for  the  acquisition  of  an  organ,  such  as  tissue  typing,  organ  preservation,  transport  of  organs, 
donor  evaluation  and  other  acquisition  costs.  The  separate  payments  for  these  costs  are  determined  on  a  reasonable  cost  basis  established  through  the 
transplant  center’s  Medicare  cost  report.  The  costs  incurred  by  transplant  centers  for  the  organ-specific  OCS  Console,  OCS  Perfusion  Sets  and  OCS 
Solutions are classified as organ acquisition costs for which Medicare provides additional reimbursement. However, Medicare does not reimburse for items 
determined  not  to  be  reasonable  and  necessary  for  diagnosis  or  treatment  of  an  illness  or  injury.  The  CMS  and  Medicare  contractors  who  administer 
Medicare  around  the  country  have  substantial  discretion  in  determining  whether  the  OCS  is  reasonable  and  necessary  in  this  context.  Either  CMS  or  a 
Medicare contractor might determine that Medicare will not cover and reimburse for the cost of the OCS in the absence of reliable clinical data evidencing 
the benefits to patients of the use of the OCS. The data we collect from our prior, ongoing and planned clinical studies and patient registry may not be 
sufficient for this purpose in a coverage determination by CMS or a Medicare contractor. Accordingly, Medicare might not reimburse transplant centers for 
all or a portion of the cost of the OCS. We believe that private insurers and other public insurers in the United States generally will follow the coverage and 
payment policies of Medicare. 

Outside of the United States, reimbursement and funding systems vary significantly by country, and within some countries, by region. Many foreign 
markets have government managed healthcare systems that govern reimbursement and funding for medical devices and procedures. In the European Union 
member states, the costs associated with organ transplant procedures may be paid for by national insurance and in some cases private insurers or by both 
national insurance and private insurers, depending on the priorities established by individual programs. These reimbursement arrangements are subject to 
complex rules and regulations at the national and regional levels that can vary between member states of the European Union and may require that we 
perform  additional  clinical  studies  to  demonstrate  that  the  OCS  is  superior  to  existing  preservation  methods.  We  have  no  studies  currently  planned  to 
collect such clinical data, and any studies of this kind likely would be expensive and lengthy and may not ultimately produce results adequate to secure 
reimbursement. In some cases, we might not be able to secure adequate reimbursement for the OCS at all or until we have collected additional clinical data 
supporting the benefits associated with the use of the OCS in transplant procedures. Hospitals or surgeons in countries or regions where separate additional
reimbursement  or  funding  for  the  OCS  is  not  available  may  determine  that  the  benefits  of  the  OCS  do  not  or  will  not  outweigh  the  cost  of  the  OCS. 
Alternatively, we may be required to enter into risk sharing arrangements with payers.

52

 
Adoption of our products in the European Union may be hindered if they impede our customer’s compliance with the requirements of Directive 
2010/53/EU (formerly Directive 2010/45/EU), and the Quality and Safety of Organs Intended for Transplantation Regulations 2012 (Statutory Instrument 
(SI)  2012  No.  1501)  (the  Regulations)  in  the  United  Kingdom  which  imposes  certain  standards  on  procurement,  preservation  and  transport  of  organs 
intended for transplantation. Even where reimbursement or funding is available, in some foreign countries, particularly in the European Union, the pricing 
of medical devices is subject to governmental control. In these countries, reimbursement and pricing negotiations with governmental authorities can take 
considerable time after the CE marking of a product. For example, some foreign reimbursement systems provide for limited payments in a given period 
and, therefore, result in extended payment periods, which could hinder adoption of the OCS for use in transplantation, limiting sales. If reimbursement of 
our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, it may not be profitable to sell our products in certain 
foreign countries, which could negatively affect the long-term growth of our business. 

Even if existing reimbursement and funding arrangements of governmental programs and other third-party payors provide for sufficient payments to 
make  purchases  of  the  OCS  cost-effective  for  hospitals,  the  laws  and  regulations  governing  these  arrangements  are  subject  to  change.  The  continuing 
efforts of governments, insurance companies and other payors of healthcare costs to contain or reduce these costs could lead to legislative or regulatory 
reform of the United States or foreign reimbursement and funding systems in a manner that significantly reduces or eliminates reimbursement for the OCS 
or for transplant procedures. 

If  hospitals  in  the  United  States  or  the  European  Union  are  not  able  to  obtain  reimbursement  or  funding  for  the  cost  of  the  OCS  and  additional 
disposable  sets  or  for  transplant  procedures  generally,  they  may  not  have  sufficient  economic  incentives  to  purchase  the  OCS.  If  hospitals  or  surgeons 
determine that the benefits of the OCS do not or will not outweigh the initial cost and ongoing expense of the OCS, we might fail to achieve significant 
sales and may never become profitable.

Reimbursement  in  international  markets  is  likely  to  require  us  to  undertake  country-specific  reimbursement  activities,  including  additional 

clinical studies, which could be time-consuming and expensive and may not yield acceptable reimbursement rates. 

In international markets, market acceptance of our products will likely depend in large part on the availability of reimbursement within prevailing 
healthcare payment systems. Reimbursement and healthcare payment systems in international markets vary significantly by country, and by region in some 
countries, and include both government-sponsored healthcare and private insurance. We may not obtain international reimbursement approvals in a timely 
manner, if at all. In addition, even if we do obtain international reimbursement approvals, the level of reimbursement may not be enough to commercially 
justify expansion of our business into the approving jurisdiction. To the extent we or our customers are unable to obtain reimbursement for products in 
major international markets in which we seek to market and sell our products, our international revenue growth would be harmed, and our business and 
results of operations would be adversely affected. 

If we modify our products, we may be required to obtain approval of new PMAs or PMA supplements, vary existing CE Marking, and may be 

required to cease marketing or recall any modified products until the required approvals are obtained. 

Certain modifications to a PMA-approved device or to its manufacturing processes require approval of a new PMA or a PMA supplement, while 
other modifications can be reported in an annual report or through a 30-day Notice. The FDA may not agree with our decisions regarding whether a new 
PMA or PMA supplement is necessary. We may make modifications to our approved devices and manufacturing processes in the future that we believe do 
not require approval of a new PMA application or PMA supplement, or submission of a 30-day Notice. If the FDA disagrees with our determination and 
requires us to submit a new PMA, PMA supplement or 30-day Notice for modifications to our previously approved products or manufacturing processes, 
we may be required to cease marketing or to recall the modified product until we obtain approval or submit the 30-day Notice, and we may be subject to 
significant  regulatory  fines  or  penalties.  In  addition,  the  FDA  may  not  approve  our  products  for  any  future  indications  that  are  desirable  for 
commercialization or could require clinical trials to support any modification to the device or any modified indications or claims. Any delay or failure in 
obtaining required approvals would adversely affect our ability to introduce new or enhanced products in a timely manner, which in turn would harm our 
future growth. 

Additionally, any significant change to the quality system or the product range in relation to a CE Marked device will require notification to the 
notified body which certified the product. The notified body will assess the proposed change. We might not be able to have the CE Mark varied without 
taking  additional  steps,  or  at  all.  For  example,  we  might  need  to  conduct  additional  clinical  trials  and  provide  additional  technical  information  to  the 
appropriate notified body before the CE Mark can be affixed to the changed product.

53

 
If we fail to comply with the FDA’s QSR, or FDA or EU requirements that pertain to clinical trials or investigations, the FDA or the relevant EU 

competent authority could take various enforcement actions, including halting our manufacturing operations, and our business would suffer. 

In the United States, as a manufacturer of a medical device, we are required to demonstrate and maintain compliance with the FDA’s QSR. The QSR 
is  a  complex  regulatory  scheme  that  covers  the  methods  and  documentation  of  the  design,  testing,  control,  manufacturing,  labeling,  quality  assurance, 
packaging, storage and shipping of medical devices. In February 2024 FDA issued the QSMR Final Rule to amend the QSR, incorporating by reference 
ISO 13485:2016. Until the QSMR becomes effective on February 2, 2026, we are required to comply with the QSR. The FDA enforces the QSR through 
periodic inspections and unannounced “for cause” inspections. 

We are subject to periodic FDA inspections to determine compliance with QSR and pursuant to the Bioresearch Monitoring Program, which have in 
the past and may in the future result in the FDA issuing Form 483s, including during the conduct of clinical trials. Outside the United States, our products 
and  operations  are  also  often  required  to  comply  with  standards  set  by  industrial  standards  bodies,  such  as  the  International  Organization  for 
Standardization.  For  example,  in  the  European  Union  the  MDR  includes  detailed  requirements  for  clinical  investigations,  which  are  in  line  with  the 
international  standard  ISO  14155:2020  on  good  clinical  practical,  or  GCP.  Foreign  regulatory  bodies  may  evaluate  our  products  or  the  testing  that  our 
products  undergo  against  these  standards.  The  specific  standards,  types  of  evaluation  and  scope  of  review  differ  among  foreign  regulatory  bodies.  Our 
failure to comply with FDA or local requirements that pertain to clinical trials/investigations, including GCP requirements, and the QSR (in the United 
States), or failure to take satisfactory and prompt corrective action in response to an adverse inspection, could result in enforcement actions, including a 
warning letter, adverse publicity, a shutdown of or restrictions on our manufacturing operations, delays in approving or clearing our products, refusal to 
permit  the  import  or  export  of  our  product,  prohibition  on  sales  of  our  product,  a  recall  or  seizure  of  our  products,  fines,  injunctions,  civil  or  criminal 
penalties, or other sanctions, any of which could cause our business and operating results to suffer. 

We may not be able to obtain or maintain regulatory qualifications outside the United States, which could harm our business. 

Sales  of  the  OCS  outside  the  United  States  are  subject  to  foreign  regulatory  requirements  that  vary  widely  from  country  to  country.  The  foreign 
regulatory approval process generally includes all of the risks associated with obtaining FDA clearance or approval in addition to other risks. Complying 
with  international  regulatory  requirements  can  be  an  expensive  and  time-consuming  process,  and  approval  is  not  certain.  The  time  required  to  obtain 
foreign clearances or approvals may exceed the time required for FDA clearance or approval, and requirements for such clearances or approvals may differ 
significantly from FDA requirements. Foreign regulatory authorities may not clear or approve our product for the same uses cleared or approved by the 
FDA. In addition, we may not be able to affix the CE Mark to new or modified products and we may fail to obtain any additional regulatory qualifications, 
clearances or approvals or to comply with additional legal obligations required by the individual member states of the European Union or other countries in 
which we seek to market the OCS. The FDA also regulates the export of medical devices from the United States. If we are not successful in obtaining and 
maintaining foreign regulatory approvals or complying with U.S. export regulations, our business will be harmed. 

Foreign regulatory agencies periodically inspect manufacturing facilities both in the United States and abroad. While we implement corrective and 
preventive action related to any inspection observations, we may fail to pass future inspections of our facility by applicable regulatory authorities or entities 
both in the United States and in other countries. Delays in receiving necessary qualifications, clearances or approvals to market our product outside the 
United States, or the failure to receive those qualifications, clearances or approvals, or to comply with other foreign regulatory requirements, could limit or 
prevent us from marketing our products or enhancements in international markets. Additionally, the imposition of new requirements could significantly 
affect our business and our product, and we might not be able to adjust to such new requirements. If we fail to comply with applicable foreign regulations, 
we could face substantial penalties and our business, financial condition, operating results, cash flows and prospects could be adversely affected. 

54

 
We could face product liability suits or regulatory delays due to defects in the OCS, which could be expensive and time-consuming and result in 

substantial damages payable by us and increases in our insurance rates. 

If our products are deemed to be defectively designed, manufactured or labeled, contain defective components, suffer security failures or are hacked, 
or are counterfeited, we could face substantial and costly litigation by transplant centers that purchase or use the OCS or by their patients or others claiming 
damages on their behalf. Moreover, transplantations are complex and inherently risky medical procedures. Many of the patients currently on a waiting list 
for a lung, heart or liver transplant already are very sick, with some of them receiving intensive care. All of these patients have a significant risk of death if 
they do not receive a transplant. Thus, we may incur substantial liability if the OCS fails to perform as expected and, as a result of this failure, patients do 
not receive the intended transplants or receive transplants that are not successful. Although death is an anticipated adverse event of the organ transplant 
population, if the rate of deaths or other serious adverse events using the OCS is greater than expected using conventional transplant procedures, transplant 
surgeons may cease using the OCS as often or at all, which could materially and adversely affect our business, financial condition, operating results, cash 
flows and prospects. 

Because the OCS represents a novel approach to organ transplantation, a patient or transplant center may choose to name us as a party to a lawsuit 
relating to the use of the OCS in connection with a planned or completed transplant procedure regardless of whether the OCS caused or contributed to a 
serious adverse event or death of a patient. Any claim, whether or not we are ultimately successful, could divert management’s attention from our core 
business, be expensive to defend and result in sizable damage awards against us. 

Currently,  we  maintain  global  product  liability  insurance  covering  damages  of  up  to  $10  million  per  occurrence  for  both  the  human  clinical  and 
commercial  use  of  our  product.  We  also  maintain  local  insurance  policies  as  required.  Our  current  insurance  coverage  might  not  be  sufficient  to  cover 
future claims and is subject to deductibles. Moreover, in the future, we may not be able to obtain insurance in amount or scope sufficient to provide us with 
adequate coverage against potential liabilities. Any product liability claims brought against us, with or without merit, could increase our product liability 
insurance rates or prevent us from securing continuing coverage, could harm our reputation in the industry, impair our current or future preclinical studies 
or clinical trials, hinder acceptance of our products in the market and reduce product sales. Furthermore, we would need to pay any product liability losses 
in excess of our insurance coverage or within the deductibles provided under our insurance policies applicable to the claim out of cash reserves, which 
could materially and adversely affect our business, financial condition, operating results, cash flows and prospects. 

The  FDA  has  warned  that  the  threat  of  cyberattacks  on  medical  devices  is  no  longer  theoretical.  Hackers  and  other  third  parties  may  try  to 
circumvent security controls on an OCS to gain access to information on the OCS, alter the way an OCS operates, to act as a trojan horse or other entry 
point to other systems that could lead to those systems suffering cybersecurity breaches or attacks, or to cause harms to transplanted organs or individuals. 
If our security controls fail to fully protect the OCS and the information on it, we could suffer reputational harm, could undergo regulatory investigations 
and enforcement, or could have claims brought against us. 

Third  parties  may  attempt  to  produce  counterfeit  versions  of  our  products,  which  may  harm  our  ability  to  sell  the  OCS  and  its  components, 

negatively affect our reputation or harm patients and subject us to product liability. 

Counterfeit medical devices are an increasing presence on the market. Third parties may seek to develop, manufacture, distribute and sell systems 
that we believe infringe our proprietary rights, which would compete against the OCS and impair our ability to sell the OCS in jurisdictions in which our 
proprietary rights are not upheld. In addition, counterfeit products may be promoted in a way that misleads consumers into believing they are affiliated with 
us. If a counterfeit version of the OCS were to appear on the market, we would expect to be obliged to verify all OCS products currently on the market, and 
possibly to withdraw all OCS products from the market while verifications are made. We also might be named in a lawsuit relating to any side effects or 
fatalities allegedly related to the use of a counterfeit OCS irrespective of whether the counterfeit device in fact contributed to such an adverse event or 
whether we were aware of the existence of the counterfeit device. 

55

 
Improper marketing or promotion of our products or misuse or off-label use of the OCS may harm our reputation in the marketplace, result in 
injuries that lead to product liability suits or result in costly investigations, fines or sanctions by regulatory bodies if we are deemed to have engaged in 
the promotion of these uses, any of which could be costly to our business. 

Our OCS products have been approved for marketing in the United States, European Union and other jurisdictions for specific indications, and our 
promotional materials and training methods must comply with regulatory requirements in the countries where they are sold. We train our commercial team 
to not promote the OCS for uses outside of the approved indications for use/intended purpose, known as “off-label uses.” We cannot, however, prevent a 
surgeon from using the OCS off-label, when in the surgeon’s independent professional medical judgment he or she deems it appropriate. There may be 
increased risk of injury to patients if surgeons attempt to use the OCS off-label. Furthermore, the use of the OCS for indications other than those approved 
by the FDA/ by any foreign regulatory body or for which they are CE marked may not effectively treat such conditions, which could harm our reputation in 
the marketplace among surgeons and patients. 

If the FDA or any foreign regulatory body determines that our promotional materials or training constitute promotion of an off-label use, or that the 
materials  or  training  are  false  or  misleading,  it  could  request  that  we  modify  our  training  or  promotional  materials  or  subject  us  to  regulatory  or 
enforcement  actions,  including  the  issuance  or  imposition  of  a  warning  letter,  an  untitled  letter  (which  is  used  for  violations  that  do  not  necessitate  a 
warning  letter),  injunction,  seizure,  civil  fine  or  criminal  penalties.  In  the  EU  the  MDR  expressly  prohibits  misleading  claims  in  the  form  of  off-label 
promotion and the MDR grants enforcement powers to national competent authorities. It is also possible that other federal, state or foreign enforcement 
authorities might take action under other regulatory authority, such as false claims laws or consumer protection laws, if they consider our business activities 
to  constitute  promotion  of  an  off-label  use,  which  could  result  in  significant  penalties,  including,  but  not  limited  to,  criminal,  civil  and  administrative 
penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs and the curtailment of our operations. 

In addition, surgeons may misuse the OCS or use improper techniques if they are not adequately trained, potentially leading to unsatisfactory patient 
outcomes, patient injuries, negative publicity and an increased risk of product liability. If the OCS is misused or used with improper technique, we may 
become subject to costly litigation by our customers or their patients. Similarly, in an effort to decrease costs, surgeons may also reuse the component and 
accessories of the OCS that are intended for a single use or may purchase reprocessed OCS components from third-party reprocessors in lieu of purchasing 
new  components  from  us,  which  could  result  in  product  failure  and  liability.  As  described  above,  product  liability  claims  could  divert  management’s 
attention from our core business, be expensive to defend and result in sizeable damage awards against us that may not be covered by insurance. 

Legislative or regulatory reforms in the United States or other jurisdictions may make it more difficult and costly for us to obtain regulatory 

clearances or approvals for our products or to manufacture, market or distribute our products after clearance or approval is obtained. 

From time to time, legislation is drafted and introduced in the U.S. Congress that could significantly change the statutory provisions governing the 
regulation of medical devices. In addition, FDA regulations and guidance may be revised or reinterpreted by the FDA in ways that may significantly affect 
our  business  and  our  products.  Any  new  statutes,  regulations  or  revisions  or  reinterpretations  of  existing  regulations  may  impose  additional  costs  or 
lengthen review times of any future products or make it more difficult to obtain approval for, manufacture, market or distribute our products. We cannot 
determine  what  effect  changes  in  regulations,  statutes,  legal  interpretation  or  policies,  when  and  if  promulgated,  enacted  or  adopted  may  have  on  our 
business  in  the  future.  Such  changes  could,  among  other  things,  require  additional  testing  prior  to  obtaining  clearance  or  approval;  changes  to 
manufacturing methods; recall, replacement or discontinuance of our products; or additional record keeping. 

In the EU, Regulation (EU) 2017/745, or the MDR, repealed and replaced the Medical Devices Directive (93/42/EEC) with effect from May, 26 
2021. Although the MDR now applies so all new devices placed on the market must be CE marked under it, under the transition period granted by the 
MDR, certificates issued by notified bodies for medical devices under the Medical Devices Directive before May 26, 2021 potentially remain valid (subject 
to certain Conditions) and the devices may continue to be placed on the EU market potentially until the end of December 2027 or 2028 (depending on the 
class of device) and provided the manufacturer satisfies certain requirements, including that there are no significant changes in the design and intended 
purpose of these devices. Post-Brexit the MDR applies in Northern Ireland in accordance with the Northern Ireland Protocol but does not apply in Great 
Britain (England, Wales and Scotland). The UK Medicines and Healthcare products Regulatory Agency (MHRA) has provided a transitional period under 
which the UK will recognize EU CE marks until June 30, 2030 (subject to certain conditions). To be placed on the market in Great Britain after this date, 
medical devices must have undergone a conformity assessment in accordance with UK legislation and have the UKCA mark affixed.

56

 
All of our products that were previously certified under the Medical Devices Directive, including OCS Heart, OCS Liver and OCS Lung systems, 
which includes the OCS Console, the OCS disposables, and the OCS solution additives, have now been recertified under the MDR. We received the CE 
Mark for the OCS Liver combined with our solution additives under the MDR in May 2023, with an effective date of April 2023.

We also recognize that our products may need to be certified and have a UKCA mark affixed to be placed on the market in Great Britain in the 
future. However, although neither the EU MDR nor EU IVDR apply in Great Britain, the national UK medical devices rules currently allow manufacturers 
to place devices CE marked under the EU MDR or EU IVDR (including their relevant transition periods) on the market in Great Britain, potentially up 
until June 30, 2030, provided certain conditions are met. The UK Government is expected to publish updated UK medical devices legislation in 2025. This 
might  lead  to  substantial  changes  in  the  regulatory  framework/requirements  imposed  on  medical  devices.  We  will  need  to  continue  to  monitor  the 
developments in the UK to assess how they impact our devices sold in Great Britain

We are subject to certain federal, state and foreign fraud and abuse laws, health information privacy and security laws and transparency laws, 
which, if violated, could subject us to substantial penalties. Additionally, any challenge to or investigation into our practices under these laws could 
cause adverse publicity and be costly. 

There are numerous U.S. federal and state, as well as foreign, laws pertaining to healthcare fraud and abuse, including anti-kickback, false claims 
and physician transparency laws. Our business practices and relationships with providers are subject to scrutiny under these laws. We may also be subject 
to privacy and security regulation related to patient, customer, employee and other third-party information by both the federal government and the states 
and foreign jurisdictions in which we conduct our business. The healthcare laws and regulations that may affect our ability to operate include, but are not 
limited to: 

•

•

•

•

the federal Anti-Kickback Statute, which prohibits, among other things, persons and entities 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, in whole or in part, under federal healthcare programs, such as Medicare and 
Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation. 
The  U.S.  government  has  interpreted  this  law  broadly  to  apply  to  the  marketing  and  sales  activities  of  manufacturers.  Moreover,  the 
government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a 
false  or  fraudulent  claim  for  purposes  of  the  federal  civil  False  Claims  Act.  Violations  of  the  federal  Anti-Kickback  Statute  may  result  in 
substantial  civil  monetary  and  criminal  penalties.  Similarly,  violations  can  result  in  exclusion  from  participation  in  government  healthcare 
programs, including Medicare and Medicaid;

the federal civil and criminal false claims laws and civil monetary penalties laws, including the federal civil False Claims Act, which prohibit, 
among  other  things,  individuals  or  entities  from  knowingly  presenting,  or  causing  to  be  presented,  claims  for  payment  from  Medicare, 
Medicaid or other federal healthcare programs that are false or fraudulent. These laws can apply to manufacturers who provide information on 
coverage, coding, and reimbursement of their products to persons who bill private payors. Private individuals can bring False Claims Act “qui 
tam”  actions,  on  behalf  of  the  government  and  such  individuals,  commonly  known  as  “whistleblowers,”  may  share  in  amounts  paid  by  the 
entity  to  the  government  in  fines  or  settlement.  When  an  entity  is  determined  to  have  violated  the  federal  civil  False  Claims  Act,  the 
government may impose substantial civil fines and penalties, and exclude the entity from participation in Medicare, Medicaid and other federal 
healthcare programs;

the federal Civil Monetary Penalties Law, which prohibits, among other things, offering or transferring remuneration to a federal healthcare 
beneficiary  that  a  person  knows  or  should  know  is  likely  to  influence  the  beneficiary’s  decision  to  order  or  receive  items  or  services 
reimbursable by the government from a particular provider or supplier;

HIPAA,  which  created  additional  federal  criminal  statutes  that  prohibit,  among  other  things,  executing  a  scheme  to  defraud  any  healthcare 
benefit  program  and  making  false  statements  relating  to  healthcare  matters.  Similar  to  the  federal  Anti-Kickback  Statute,  a  person  or  entity 
does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation;

the  federal  Physician  Sunshine  Act  under  the  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education 
Reconciliation  Act,  collectively  referred  to  as  the  Affordable  Care  Act,  which  require  certain  applicable  manufacturers  of  drugs,  devices, 
biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program to report 
annually to CMS information related to payments and other transfers of value to physicians and teaching hospitals. Applicable manufacturers 
are required to submit annual reports to CMS. Failure to submit required information may result in substantial civil monetary penalties;

many countries in which we operate have laws with extra-territorial effect-those laws apply to our operations outside the relevant country, to 
the extent they are breached. Examples of such laws include: the FCPA, Bribery Act and the GDPR. The extra-territorial effect of those laws 
affects our sales and marketing strategy, since in many countries healthcare professionals are officers of the state. This is particularly important 
in the context of bribery offences, which in the UK and in the United States include the offence of bribing a foreign public official. Failure by 
our sales staff to comply with those laws may result in criminal and civil penalties and damage our reputation; and

analogous state and foreign law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to 
items  or  services  reimbursed  by  any  private  payor,  including  commercial  insurers  or  patients;  state  laws  that  require  device  companies  to 
comply with the industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government or 
otherwise  restrict  payments  that  may  be  made  to  healthcare  providers  and  other  potential  referral  sources;  state  laws  that  require  device 
manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing 
expenditures;  consumer  protection  and  unfair  competition  laws,  which  broadly  regulate  marketplace  activities  and  activities  that  potentially 
harm  customers,  foreign  and  state  laws,  including  the  GDPR,  governing  the  privacy  and  security  of  health  information  in  certain 
circumstances,  many  of  which  differ  from  each  other  in  significant  ways  and  may  not  have  the  same  effect,  thus  complicating  compliance 
efforts; and state laws related to insurance fraud in the case of claims involving private insurers.

These laws and regulations, among other things, constrain our business, marketing and other promotional activities by limiting the kinds of financial 
arrangements, including sales programs, we may have with customers, physicians or other potential purchasers of our products. In particular, these laws 
will influence, among other things, how we structure our sales offerings, including discount and rebate practices, customer support, education and training 
programs, and physician consulting and other service arrangements. Due to the breadth of these laws, the narrowness of statutory exceptions and regulatory 
safe  harbors  available,  and  the  range  of  interpretations  to  which  they  are  subject,  it  is  possible  that  some  of  our  current  or  future  practices  might  be 
challenged under one or more of these laws. 

To enforce compliance with the healthcare regulatory laws, certain enforcement bodies have recently increased their scrutiny of interactions between 
healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare 
industry.  For  example,  the  member  states  of  the  European  Union  closely  monitor  perceived  unlawful  marketing  activity  by  companies,  including 
inducement  to  prescribe  and  the  encouragement  of  off-label  use  of  devices.  Responding  to  investigations  can  be  time-and  resource-consuming  and  can 
divert management’s attention from the business. Additionally, as a result of these investigations, healthcare providers and entities may have to agree to 
additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement. Any such investigation or settlement could 
increase  our  costs  or  otherwise  have  an  adverse  effect  on  our  business.  Even  an  unsuccessful  challenge  or  investigation  into  our  practices  could  cause 
adverse publicity and be costly to respond to. If our operations are found to be in violation of any of the healthcare laws or regulations described above or 
any  other  healthcare  regulations  that  apply  to  us,  we  may  be  subject  to  penalties,  including  administrative,  civil  and  criminal  penalties,  damages,  fines, 
exclusion from participation in government healthcare programs, such as Medicare and Medicaid, imprisonment, contractual damages, reputational harm, 
disgorgement  and  the  curtailment  or  restructuring  of  our  operations.  Moreover,  industry  associations  closely  monitor  the  activities  of  their  member 
companies.  If  these  organizations  or  national  authorities  were  to  name  us  as  having  breached  our  obligations  under  their  laws,  regulations,  rules  or 
standards, our reputation would suffer and our business, financial condition, operating results, cash flows and prospects could be adversely affected. 

58

 
Failure  to  comply  with  anti-bribery,  anti-corruption,  and  anti-money  laundering  laws,  including  the  FCPA,  as  well  as  export  control  laws, 
customs laws, sanctions laws and other laws governing our operations could result in civil or criminal penalties, other remedial measures and legal 
expenses. 

As we grow our international presence, we are increasingly exposed to trade and economic sanctions and other restrictions imposed by the United 
States,  the  European  Union  and  other  governments  and  organizations.  The  U.S.  Departments  of  Justice,  Commerce,  State  and  U.S.  Treasury  and  other 
federal  agencies  and  authorities  have  a  broad  range  of  civil  and  criminal  penalties  they  may  seek  to  impose  against  corporations  and  individuals  for 
violations of economic sanctions laws, export control laws, the FCPA and other federal statutes and regulations, including those established by the Office of 
Foreign Assets Control, or OFAC. In addition, the Bribery Act prohibits both domestic and international bribery, as well as bribery across both private and 
public sectors. The substantive offences of offering or receiving a bribe will be committed by an individual where either the bribery takes place in the U.K, 
or the person paying or receiving the bribe has a close connection with the UK An organization which is either incorporated in or carries on part of its 
business in the U.K will be liable under the Bribery Act if a person associated with the organization (being persons performing services for it) pays a bribe 
anywhere in the world intending to obtain or retain business for the organization. This is a strict liability offense with the only defenses available being that 
the organization implemented “adequate procedures” to prevent bribery or it was reasonable for it to not have such procedures in place. Under these laws 
and  regulations,  as  well  as  other  anti-corruption  laws,  anti-money  laundering  laws,  export  control  laws,  customs  laws,  sanctions  laws  and  other  laws 
governing  our  operations,  various  government  agencies  may  require  export  licenses,  may  seek  to  impose  modifications  to  business  practices,  including 
cessation  of  business  activities  in  sanctioned  countries  or  with  sanctioned  persons  or  entities  and  modifications  to  compliance  programs,  which  may 
increase compliance costs, and may subject us to fines, penalties and other sanctions. A violation of these laws or regulations would negatively affect our 
business, financial condition and results of operations. Due to sales of our products to government or government-affiliated entities, we may be exposed to 
heightened risk of potential violations of the FCPA, the Bribery Act, or other relevant law. 

We  have  implemented  policies  and  procedures  designed  to  ensure  compliance  by  us  and  our  directors,  officers,  employees,  representatives, 
consultants  and  agents  with  the  FCPA,  OFAC  restrictions,  the  Bribery  Act  and  other  export  control,  anti-corruption,  anti-money-laundering  and  anti-
terrorism  laws  and  regulations.  We  cannot  be  certain,  however,  that  our  policies  and  procedures  are  or  will  be  sufficient  or  that  directors,  officers, 
employees, representatives, consultants and agents have not engaged and will not engage in conduct for which we may be held responsible, nor can we 
provide  assurance  that  our  business  partners  have  not  engaged  and  will  not  engage  in  conduct  that  could  materially  affect  their  ability  to  perform  their 
contractual obligations to us or even result in our being held liable for such conduct. Violations of the FCPA, OFAC restrictions, the Bribery Act or other 
export control, anti-corruption, anti-money laundering and anti-terrorism laws or regulations may result in severe criminal or civil sanctions, and we may 
be subject to other liabilities, which could have a material adverse effect on our business, financial condition and results of operations. 

We are subject to, and may in the future become subject to additional, U.S., state and foreign laws and regulations imposing obligations on how 
we collect, store, process or share information concerning individuals. Our actual or perceived failure to comply with such obligations could harm our 
business. Complying with such laws could also impair our efforts to maintain and expand our customer base, and thereby decrease our revenue. 

In the conduct of our business, we may at times collect, process or share data concerning individuals, including health-related personal data. The 
U.S. federal government and various states have adopted or proposed laws, regulations, guidelines and rules for the collection, distribution, use and storage 
of  personal  information  of  individuals.  We  may  also  be  subject  to  U.S.  federal  rules,  regulations  and  guidance  concerning  cybersecurity  for  medical 
devices, including guidance from the FDA. State privacy and cybersecurity laws vary and, in some cases, can impose more restrictive requirements than 
U.S. federal law. For example, the CCPA affords California residents expanded privacy rights and protections, including civil penalties for violations and 
statutory damages under a private right of action for data security breaches. These protections were expanded by CPRA and more than a dozen states now 
have  similar  laws.  Where  state  laws  are  more  protective,  we  must  comply  with  the  stricter  provisions.  In  addition  to  fines  and  penalties  that  may  be 
imposed for failure to comply with state law, some states also provide for private rights of action to individuals for misuse of personal information. Our 
ongoing efforts to comply with evolving laws and regulations may be costly and require ongoing modifications to our policies, procedures and systems. 
Failure to comply with laws regarding data protection would expose us to risk of enforcement actions and penalties under such laws. Even if we are not 
determined to have violated applicable data laws, government investigations into these issues can be expensive and lengthy and generate adverse publicity, 
which could harm our business, financial condition, results of operations or prospects.

59

 
The EEA and the UK, as well as other international jurisdictions, also have laws and regulations dealing with the collection, use and processing of 
personal  data  concerning  individuals  who  are  located  there.  Those  laws  are  often  more  restrictive  than  those  in  the  United  States.  For  example,  we  are 
subject  to  the  requirements  of  the  GDPR,  which  imposes  more  stringent  administrative  requirements  for  controllers  and  processors  of  personal  data, 
including,  for  example,  shortened  timelines  for  data  breach  notifications,  limitations  on  retention  of  information,  increased  requirements  pertaining  to 
health  data  and  pseudonymized  (i.e.,  key-coded)  data,  additional  obligations  when  we  contract  with  service  providers,  and  more  robust  rights  for 
individuals  over  their  personal  data.  The  GDPR  provides  that  EU  member  states  may  make  their  own  further  laws  and  regulations,  including  laws  and 
regulations limiting the processing of genetic, biometric or health data, which could limit our ability to use and share personal data or cause our costs to 
increase, and harm our business and financial condition. If we do not comply with our obligations under the GDPR, we could be exposed to enforcement 
activity from EU regulators, including substantial fines and litigation. In addition, EU law restricts transfers of personal data to the United States unless 
certain requirements are met. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing 
focus on privacy and data protection issues with the potential to affect our business. For example, in July 2020, the Court of Justice of the European Union 
invalidated the U.S.-EU Privacy Shield Framework, which has led to increased scrutiny of data transfers from the EEA and the UK to the United States 
generally and may increase our costs of compliance with data privacy legislation. We rely on a mixture of mechanisms to transfer personal data from our 
European  business  to  the  United  States.  We  are  also  subject  to  the  laws  of  each  EU  member  state  implementing  any  EU  directive  applicable  to  our 
processing activities, including Directing 2002/58/EC.

We are subject to the requirements of the UK Data Protection Law as amended and superseded from time to time. UK Data Protection Law means: 
(i) the GDPR as it forms part of UK law by virtue of section 3 of the European Union (Withdrawal) Act 2018; (ii) the Data Protection Act 2018; (iii) the 
Privacy and Electronic Communications (EC Directive) Regulations 2003 as they continue to have effect by virtue of section 2 of the European Union 
(Withdrawal) Act 2018; and (iv) any other laws in the field of data protection in force in the UK from time to time applicable (in whole or in part) to us. 

Any  actual  or  perceived  failure  by  us  or  the  third  parties  with  whom  we  work  to  comply  with  data  privacy  or  security  laws,  policies,  legal 
obligations or industry standards, or any security incident that results in the unauthorized release or transfer of information concerning individuals, may 
result  in  governmental  enforcement  actions  and  investigations,  including  by  European  data  protection  authorities  and  U.S.  federal  and  state  regulatory 
authorities, fines and penalties, litigation and/or adverse publicity, including by consumer advocacy groups, and could cause our customers, their patients 
and  other  healthcare  professionals  to  lose  trust  in  us,  which  could  harm  our  reputation  and  have  a  material  adverse  effect  on  our  business,  financial 
condition and results of operations. 

Healthcare  policy  changes,  including  recently  enacted  or  potential  future  legislation  reforming  the  U.S.  healthcare  system,  could  harm  our

business, financial condition and results of operations. 

We operate in a highly regulated industry. The U.S. and state governments continue to propose and pass legislation or take administrative action that 

may affect the availability and cost of healthcare. Healthcare reform initiatives could harm our business, financial condition and results of operations.

In  the  United  States,  there  have  been  and  continue  to  be  a  number  of  legislative  initiatives  to  contain  healthcare  costs  and  improve  access  to 
transplantation. There have been and will likely continue to be ongoing healthcare reform efforts. These reform efforts have and may continue to focus on 
coverage and payment for organ procurement and transplant. For example, the Centers for Medicare & Medicaid Services issued regulations in 2020 and 
2021  that  revised  Medicare  conditions  of  participation  for  organ  procurement  organizations  as  well  as  organ  acquisition  payment  policies  for  organ 
procurement  organizations,  transplant  centers  and  donor  hospitals.  In  addition,  in  2023,  the  Securing  the  U.S.  Organ  Procurement  and  Transplantation 
Network  act  was  signed  into  law,  which  allows  HRSA  to  make  changes  to  the  Organ  Procurement  and  Transplantation  Network  (OPTN),  including 
requiring an independent board, awarding contracts to both non-profit and for-profit entities, and eliminating the cap on funding. 

We expect additional state and federal healthcare policies and reform measures to be adopted in the future, any of which could limit coverage or 
reimbursement for healthcare products and services or otherwise result in reduced demand for the OCS or additional pricing pressure and have a material 
adverse  effect  on  our  industry  generally  and  on  our  customers.  Any  changes  of,  or  uncertainty  with  respect  to,  coverage  or  reimbursement  of  services 
provided by organ procurement organizations, transplant centers or hospitals could affect demand for the OCS, which in turn could have a material adverse 
effect on our business, financial condition and results of operations. 

60

 
In  addition,  other  broader  legislative  changes  have  been  adopted  that  could  have  an  adverse  effect  upon,  and  could  prevent,  our  products’ 
commercial success. The Budget Control Act of 2011, as amended, or the Budget Control Act, includes provisions intended to reduce the federal deficit, 
including  reductions  in  Medicare  payments  to  providers  through  2030  (except  May  1,  2020  to  March  31,  2022).  Any  significant  spending  reductions 
affecting  Medicare,  Medicaid,  or  other  publicly  funded  or  subsidized  health  programs,  or  any  significant  taxes  or  fees  imposed  as  part  of  any  broader 
deficit  reduction  effort  or  legislative  replacement  to  the  Budget  Control  Act,  or  otherwise,  could  have  an  adverse  impact  on  our  anticipated  product 
revenue.

Our  business  activities  involve  the  use  of  hazardous  materials,  which  require  compliance  with  environmental  and  occupational  safety  laws 

regulating the use of such materials. If we violate these laws, we could be subject to significant fines, liabilities or other adverse consequences. 

Our  research  and  development  programs  involve  the  controlled  use  of  hazardous  materials.  Accordingly,  we  are  subject  to  international,  federal, 
state and local laws governing the use, handling and disposal of these materials. Although we believe that our safety procedures for handling and disposing 
of these materials comply in all material respects with applicable regulations, we cannot eliminate the risk of accidental contamination or injury from these 
materials. In the event of an accident or failure to comply with environmental laws, we could be held liable for damages that result, and any such liability 
could  exceed  our  assets  and  resources.  Our  general  liability  and  umbrella  insurance  policies  provide  for  coverage  up  to  annual  aggregate  limits  of  $2 
million per occurrence but exclude coverage for liabilities relating to the release of pollutants. The insurance that we currently hold may not be adequate to 
cover all liabilities relating to accidental contamination or injury due to pollution conditions or other extraordinary or unanticipated events. Furthermore, an 
accident could damage or force us to shut down our operations.

Risks Related to Our Common Stock and General Risks 

The market price of our common stock has been and may continue to be volatile and could subject us to securities class action litigation. 

During the year ended December 31, 2023, the price per share of our common stock has ranged from as low as $36.42 to as high as $99.63. Some of 

the factors that may cause the market price of our common stock to fluctuate include: 

•

•

•

•

•

•

•

•

•

•

•

•

price and volume fluctuations in the overall stock market;

volatility in the market price and trading volume of comparable companies;

actual or anticipated changes in our earnings or fluctuations in our operating results or in the expectations of securities analysts;

results of post-approval studies or clinical trials relating to next generation products for the OCS or competing products;

failure or discontinuation of any of our product development and research programs;

regulatory or legal developments in the United States and other countries, including changes in the healthcare payment systems;

results or changes in the status of, or developments relating to, applications for regulatory approvals or clearances for the OCS or competing 
products;

our announcements or our competitors’ announcements of new products, procedures or therapies;

departure of key personnel;

litigation involving us or that may be perceived as having an adverse effect on our business;

developments or disputes concerning patent applications, issued patents or other proprietary rights;

market conditions in the medical device and biotechnology sectors;

61

 
•

•

•

changes in general economic, industry and market conditions and trends;

investors’ general perception of us; and

sales of large blocks of our stock.

The market for medical device and biotechnology companies, in particular, has experienced extreme price and volume fluctuations that have often 
been  unrelated  or  disproportionate  to  changes  in  the  operating  performance  of  the  companies  whose  stock  is  experiencing  those  price  and  volume 
fluctuations. Because of the potential volatility of our stock price, we may become the target of securities litigation in the future. Securities litigation could 
result in substantial costs and divert management’s attention and resources from our business. 

If  securities  or  industry  analysts  issue  an  adverse  or  misleading  opinion  regarding  our  business  or  do  not  publish  research  or  publish 

unfavorable research about our business, our stock price and trading volume could decline. 

The  trading  market  for  our  common  stock  is  influenced  by  the  research  and  reports  that  industry  or  securities  analysts  publish  about  us  or  our 
business. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, we could lose visibility in the financial 
markets,  which  in  turn  could  cause  our  stock  price  or  trading  volume  to  decline.  Moreover,  if  any  of  the  analysts  who  cover  us  issue  an  adverse  or 
misleading  opinion  regarding  us,  our  business  model  or  our  stock  performance,  or  if  our  operating  results  fail  to  meet  the  expectations  of  the  investor 
community, one or more of the analysts who cover our company may change their recommendations regarding our company, and our stock price could 
decline. 

We have adopted anti-takeover provisions in our restated articles of organization and amended and restated bylaws and are subject to provisions 
of  Massachusetts  law  that  may  frustrate  any  attempt  to  remove  or  replace  our  current  board  of  directors  or  to  effect  a  change  of  control  or  other 
business combination involving our company. 

Our restated articles or organization and amended and restated bylaws and certain provisions of Massachusetts law may discourage certain types of 
transactions  involving  an  actual  or  potential  change  of  control  of  our  company  that  might  be  beneficial  to  us  or  our  security  holders.  For  example,  our 
amended and restated bylaws grant the chairperson presiding over any meetings of shareholders the right to adjourn such meeting. Our board of directors 
also may issue shares of any class or series of preferred stock in the future without shareholder approval and upon such terms as our board of directors may 
determine.  The  rights  of  the  holders  of  our  common  stock  will  be  subject  to,  and  may  be  harmed  by,  the  rights  of  the  holders  of  any  class  or  series  of 
preferred stock that may be issued in the future. Massachusetts state law also prohibits us from engaging in specified business combinations unless the 
combination is approved or consummated in a prescribed manner. These provisions, alone or together, could delay hostile takeovers and changes in control 
of our company or changes in our management. 

62

 
 
 
Our restated articles of organization designate the Business Litigation Session of the Superior Court of Suffolk County, Massachusetts (or, if 
and only if the Business Litigation Session of the Superior Court of Suffolk County, Massachusetts lacks jurisdiction, another state or federal court 
located within the Commonwealth of Massachusetts) as the sole and exclusive forum for certain types of actions and proceedings that may be initiated 
by our shareholders, which could discourage lawsuits against us and our directors and officers. 

Our restated articles of organization designate the Business Litigation Session of the Superior Court of Suffolk County, Massachusetts (or, if and 
only  if  the  Business  Litigation  Session  of  the  Superior  Court  of  Suffolk  County,  Massachusetts  lacks  jurisdiction,  another  state  or  federal  court  located 
within  the  Commonwealth  of  Massachusetts)  as  the  sole  and  exclusive  forum  for  any  action  under  Massachusetts  statutory  or  common  law:  brought 
derivatively  on  our  behalf,  asserting  a  claim  of  breach  of  a  fiduciary  duty  owed  by  any  of  our  directors,  officers  or  other  employees  to  us  or  our 
shareholders,  asserting  a  claim  arising  pursuant  to  any  provision  of  the  Massachusetts  Business  Corporation  Act  or  asserting  a  claim  governed  by  the 
internal affairs doctrine, in all cases subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. In addition, our 
restated articles of organization provide that any person or entity purchasing or otherwise acquiring any interest in shares of our common stock is deemed 
to have notice of and consented to the foregoing provisions. This provision will not apply to actions arising under the Exchange Act, or the Securities Act 
of  1933,  as  amended,  or  the  Securities  Act.  Additionally,  this  exclusive  forum  provision  may  limit  the  ability  of  our  shareholders  to  bring  a  claim  in  a 
judicial forum that such shareholders find favorable for disputes with us or our directors or officers, which may discourage such lawsuits against us and our 
directors  and  officers.  Alternatively,  if  the  Business  Litigation  Session  of  the  Superior  Court  of  Suffolk  County,  Massachusetts  or  a  court  outside  of 
Massachusetts were to find this exclusive forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or 
proceedings described above, we may incur additional costs associated with resolving such matters in other venues or jurisdictions, which could materially 
and adversely affect our business, financial condition, operating results, cash flows and prospects. 

If we fail to maintain effective internal control over financial reporting and effective disclosure controls and procedures, we may not be able to 

accurately report our financial results in a timely manner or prevent fraud, which may adversely affect investor confidence in our company. 

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, as amended, our management is required to report on, and our independent registered 
public accounting firm is required to attest to, the effectiveness of our internal control over financial reporting. This assessment includes disclosure of any 
material weakness identified by our management in our internal control over financial reporting. In addition, we are required to comply with the SEC’s 
rules  implementing  Section  302  of  the  Sarbanes-Oxley  Act,  which  requires  management  to  certify  financial  and  other  information  in  our  quarterly  and 
annual reports, and we are required to disclose significant changes made in our internal controls and procedures on a quarterly basis.

If we identify a material weakness in our internal control over financial reporting, we may not be able to remediate the material weakness identified 
in a timely manner or maintain all of the controls necessary to remain in compliance with our reporting obligations. If we identify any material weaknesses 
in  our  internal  controls  over  financial  reporting  or  we  are  unable  to  comply  with  the  requirements  of  Section  404  in  a  timely  manner  or  assert  that  our 
internal controls over financial reporting are effective, or if our independent registered public accounting firm is unable to express an unqualified opinion as 
to the effectiveness of our internal control over financial reporting in future periods, investors may lose confidence in the accuracy and completeness of our 
financial reports. As a result, the market price of our common stock could be materially adversely affected. 

Changes in accounting standards and subjective assumptions, estimates and judgments by management related to complex accounting matters 

could significantly affect our financial condition and results of operations. 

Accounting  principles  and  related  pronouncements,  implementation  guidelines  and  interpretations  we  apply  to  a  wide  range  of  matters  that  are 
relevant  to  our  business,  including,  but  not  limited  to,  revenue  recognition,  leases  and  stock-based  compensation,  are  complex  and  involve  subjective 
assumptions,  estimates  and  judgments  by  our  management.  Changes  in  accounting  pronouncements  or  their  interpretation  or  changes  in  underlying 
assumptions, estimates or judgments by our management could significantly change our reported or expected financial performance.

None.

Item 1C. Cybersecurity.

We  have  adopted  processes  designed  to  identify,  assess  and  manage  material  risks  from  cybersecurity  threats  to  our  information  systems.  Those 
processes include response to and an assessment of internal and external threats to the security, confidentiality, integrity and availability of our data and 
systems  along  with  other  material  risks  to  our  operations,  at  least  annually  or  whenever  there  are  material  changes  to  our  systems  or  operations.  These 
processes  include  plans  to  be  used  in  the  event  of  a  cybersecurity  incident,  including  incident  reporting  and  business  continuity.  As  part  of  our  risk 
management process, we engage outside providers to conduct periodic internal and external penetration testing. We store our data in cloud environments 
with security appropriate to the data involved and have adopted controls around, among other things, vendor risk assessment, access and acceptable use and 
backup  and  recovery.  Although  we  have  experienced  cybersecurity  incidents  in  the  past,  cybersecurity  threats,  including  as  a  result  of  previous 
cybersecurity incidents, have not materially affected the Company, including its business strategy, results of operations or financial condition.

Our executive team, along with our Audit Committee, considers cybersecurity risk as part of our overall business strategy, financial planning and 
capital allocation. Our Audit Committee and Board of Directors engage with members of the executive team and are briefed on cybersecurity risks at least 
once each calendar year and with respect to any potentially material cybersecurity incidents. Our Chief Information Officer reports regularly, and at least 
annually, to our Audit Committee and such report may address overall assessment of our compliance with our cybersecurity policies, and include topics 
such  as  risk  assessment,  risk  management  and  control  decisions,  service  provider  arrangements,  test  results,  security  incidents  and  responses,  and 
recommendations for changes and updates to policies and procedures. Our Chief Information Officer has served in various senior information technology 
roles, responsible for information security for over 20 years.

Item 2. Properties. 

Our corporate headquarters and manufacturing and clinical training facilities are located in Andover, Massachusetts, where we lease 135,199 square 
feet of space, including a 10,500 square foot laboratory and training facility and a 7,900 square foot class 10,000 cleanroom facility. The leases for these 
facilities expire on December 31, 2027 with an option to extend the term beyond the expiration date for one additional period of five years. We also lease 
office  space  at  various  locations  in  the  United  States  for  our  NOP  and  hangar  space  for  our  aircraft,  all  under  short-term  leases.  We  are  constructing  a 
commercial aircraft hangar at Bozeman Yellowstone International Airport in Bozeman, Montana, which we will use for our flight school aircraft and office 
space for personnel located in Bozeman.

We believe that our current facilities are adequate to meet our current needs, although we may seek to negotiate new leases or evaluate additional or 

alternate space for our operations. We believe appropriate alternative space would be readily available on commercially reasonable terms. 

Item 3. Legal Proceedings. 

We are not currently subject to any material legal proceedings. From time to time, we may be involved in legal proceedings or investigations, which 
could have an adverse impact on our reputation, business and financial condition and divert the attention of our management from the operation of our 
business.

Item 4. Mine Safety Disclosures.

Not applicable.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. 

The  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  should  be  read  in  conjunction  with  our  consolidated 
financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and 
analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business, includes 
forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Item 1A. Risk Factors” 
section  of  this  Annual  Report  on  Form  10-K,  our  actual  results  could  differ  materially  from  the  results  described  in  or  implied  by  the  forward-looking 
statements contained in the following discussion and analysis. 

Overview 

We are a commercial-stage medical technology company transforming organ transplant therapy for end-stage organ failure patients across multiple 
disease  states.  We  developed  the  OCS  to  replace  a  decades-old  standard  of  care  that  we  believe  is  significantly  limiting  access  to  life-saving  transplant 
therapy  for  hundreds  of  thousands  of  patients  worldwide.  Our  innovative  OCS  technology  replicates  many  aspects  of  the  organ’s  natural  living  and 
functioning environment outside of the human body. As such, the OCS represents a paradigm shift that transforms organ preservation for transplantation 
from a static state to a dynamic environment that enables new capabilities, including organ optimization and assessment. We have also developed our NOP, 
an innovative turnkey solution to provide outsourced organ retrieval, OCS organ management and logistics services, to provide transplant programs in the 
United States with a more efficient process to procure donor organs with the OCS. In 2023, we enhanced our NOP offering with the addition of a logistics 
team to expand our transportation logistics capabilities. Our logistics services include aviation transportation, ground transportation, and other coordination 
activity. We believe the use of the OCS combined with the NOP has the potential to significantly increase the number of organ transplants and improve 
post-transplant outcomes.

We designed the OCS to be a platform that allows us to leverage core technologies across products for multiple organs. To date, we have developed 
three OCS products, one for each of heart, lung and liver transplantations, making the OCS the only FDA approved, portable, multi-organ, warm perfusion 
technology platform. All three of our products, OCS Heart, OCS Lung and OCS Liver, have received PMA from the FDA, for both DBD organs and DCD 
organs. 

Since  our  inception,  we  have  focused  substantially  all  of  our  resources  on  designing,  developing  and  building  our  proprietary  OCS  technology 
platform and organ-specific OCS products; obtaining clinical evidence for the safety and effectiveness of our OCS products through clinical trials; securing 
regulatory approval; organizing and staffing our company; planning our business; raising capital; commercializing our products; developing and growing 
our NOP; developing and expanding our market and distribution chain and providing general and administrative support for these operations. To date, we 
have  funded  our  operations  primarily  with  proceeds  from  borrowings  under  loan  agreements,  proceeds  from  the  sale  of  common  stock  in  our  public 
offerings, and revenue from clinical trials and commercial sales of our OCS products and NOP services.

Since our inception, we have incurred significant operating losses. Our ability to generate revenue sufficient to achieve sustained profitability will 
depend on the continued growth in customer utilization of our products and services. We generated total revenue of $241.6 million and incurred a net loss 
of  $25.0  million  for  the  year  ended  December  31,  2023.  As  of  December  31,  2023,  we  had  an  accumulated  deficit  of  $503.7  million.  We  expect  our 
operating and capital expenditures will continue to increase as we focus on growing commercial sales of our products in both the United States and select 
non-U.S.  markets,  including  growing  our  commercial  team,  which  will  pursue  increasing  commercial  sales  of  our  OCS  products;  growing  our  NOP, 
including by maintaining and growing our logistics capabilities, including aviation transportation, to support our NOP to reduce dependence on third party 
transportation,  including  by  means  of  the  acquisition  of  fixed-wing  aircraft  or  other  acquisitions,  joint  ventures  or  strategic  investments;  scaling  our 
manufacturing  and  sterilization  operations;  developing  the  next  generation  OCS;  continuing  research,  development  and  clinical  trial  efforts;  seeking 
regulatory clearance for new products and product enhancements, including additional indications or other organs, in both the United States and select non-
U.S. markets; and operating as a public company.

Because of the numerous risks and uncertainties associated with product development, commercialization and regulations of our industry, we are 
unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve or maintain profitability on an annual 
basis. Until such time, if ever, as we can generate substantial revenue sufficient to achieve sustained profitability, we may finance our operations through a 
combination of equity offerings, debt financings and strategic alliances. We may be unable to raise additional funds or enter into such other agreements or 
arrangements when needed on favorable terms or at all. If we are unable to raise capital or enter into such agreements as, and when, needed, we may have 
to significantly delay, scale back or discontinue the further development and commercialization efforts of one or more of our products, or may be forced to 
reduce or terminate our operations. In March 2023, the U.S. Department of Health and Human Services’ Health Resources and Services Administration, or 
HRSA, announced initiatives designed to improve the Organ Procurement and Transplantation network, or OPTN, including its intent to solicit contract 
proposals to manage the OPTN, which 

67

 
is currently operated by the United Network for Organ Sharing, or UNOS, under a contract that expires in March 2024. Additionally, on July 25, 2023 and 
July  27,  2023,  the  U.S.  House  of  Representatives  and  U.S.  Senate,  respectively,  passed  the  Securing  the  U.S.  Organ  Procurement  and  Transplantation 
Network Act, which expressly authorizes HRSA to award multiple grants, contracts or cooperative agreements to support the operation of the OPTN and 
specifies  that  the  OPTN  shall  be  operated  through  awards  that  are  distinct  from  awards  made  to  support  the  organization  tasked  with  supporting  the 
networks’ board of directors. The impact that the HRSA initiatives and the U.S. Organ Procurement and Transplantation Network Act may have on our 
business, including on our NOP, is uncertain at this time.

In May 2023, we issued and sold $460.0 million in aggregate principal amount of our 1.50% Convertible Senior Notes due 2028, or the Notes, in a 
private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The Notes were issued pursuant to an indenture, dated 
May 11, 2023. The Notes bear interest at a rate of 1.50% per year, payable semi-annually in arrears on June 1 and December 1 of each year. The Notes will 
mature on June 1, 2028, unless earlier converted, redeemed or repurchased. 

As of December 31, 2023, we had cash of $394.8 million. We believe that our cash will be sufficient for us to fund our operating expenses, capital 
expenditure requirements and debt service payments for at least 12 months following the filing of our Annual Report on Form 10-K. We have based this 
estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. See “—Liquidity and 
Capital Resources”. 

Strategic Transactions

On  August  16,  2023,  we  acquired  Summit  Aviation,  Inc.  and  Northside  Property  Group,  LLC,  or  together  Summit.  Summit  was  a  charter  flight 
operator based in Bozeman, Montana. The acquisition enabled us to add aircraft transportation services to our NOP and become a comprehensive national
provider of donor organ retrieval and delivery in the United States.

In separate transactions through December 31, 2023, we acquired 11 fixed-wing aircraft to transport donor organs as part of the services offered 
under our NOP. We have acquired two additional aircraft in 2024 and intend to acquire additional fixed-wing aircraft as we scale our fleet of aircraft to 
reduce our dependence on third party transportation providers.

On August 2, 2023, we acquired certain assets related to lung and heart perfusion technology from Bridge to Life Ltd. and its subsidiary Tevosol, 

Inc., or together BTL. We intend to further develop these technologies to expand our product offerings and indications for organ transplantation. 

Economic Impacts 

Inflation, changes in trade policies, and the imposition of duties and tariffs have and could continue to adversely impact the price or availability of 
raw  materials,  the  components  of  our  products  as  well  as  shipping  and  transportation  costs.  For  example,  the  global  economy  has  experienced  extreme 
volatility  and  disruptions,  including  significant  volatility  in  commodity,  other  material  and  labor  costs,  declines  in  consumer  confidence,  declines  in 
economic growth, supply chain interruptions, uncertainty about economic stability and record inflation globally. Unfavorable economic conditions have 
and could continue to result in a variety of risks to our business, including impacts on demand and pricing for our products and pricing and availability of 
raw materials and components for our products, which could make it difficult to forecast our inventory needs and financial results.

Components of Our Results of Operations 

Revenue 

We generate net product revenue primarily from sales of our single-use, organ-specific disposable sets used on our organ-specific OCS Consoles. To 
a lesser extent, we also generate product revenue from the sale of OCS Consoles to customers and the implied rental of OCS Consoles loaned to customers 
at no charge. For each new transplant procedure, customers purchase an additional OCS disposable set for use on the customer’s existing organ-specific 
OCS Console. We also generate service revenue by providing outsourced organ retrieval, OCS organ management and logistics services under our NOP in 
the  United  States.  With  the  acquisition  of  Summit,  the  purchase  of  fixed-wing  transplant  aircraft  and  the  addition  of  a  logistics  team,  we  anticipate 
increased service revenue from our aviation transportation service offering.

68

 
Prior to the acquisition, Summit derived its revenue primarily from charter flight services. To a lesser extent, Summit also derived revenue from 
providing  flight  school  training,  managing  aircraft  and  other  related  services.  As  part  of  the  Summit  integration,  we  have  transitioned  Summit's  charter 
flight customers and are finalizing the transition of aircraft management customers to third parties. Following this transition we do not anticipate generating 
revenue from charter flights or aircraft management and related services. We are continuing to offer flight school training services. During the year ended 
December 31, 2023, service revenue of $4.9 million, including $3.0 million of charter flight and aircraft management and related services and $1.9 million 
of flight school training revenue, is from Summit's legacy operations and is unrelated to the NOP and organ transplant. 

All of our OCS transplant-related revenue has been generated by sales to transplant centers and Organ Procurement Organizations, not-for-profit 
organizations responsible for recovering organs from deceased donors for transplantation, in the United States, Europe and Asia-Pacific, or, in some cases, 
to  distributors  selling  to  transplant  centers  in  select  countries.  Substantially  all  of  our  customer  contracts  have  multiple-performance  obligations  that 
contain  promises  consisting  of  OCS  Perfusion  Sets  and  OCS  Solutions  and  may  also  contain  promises  for  organ  retrieval,  OCS  organ  management  or 
logistics services under our NOP, and an OCS Console, whether sold or loaned to the customer. 

Through December 31, 2023, all of our sales outside of the United States have been commercial sales (unrelated to any clinical trials). Our sales in 
the  EU  are  dependent  on  obtaining  and  maintaining  the  CE  Mark  certifications  for  each  of  our  OCS  products.  As  required  by  the  MDR,  we  received 
recertification  of  the  CE  Mark  in  September  2022  for  each  of  the  OCS  Heart  and  OCS  Lung  systems,  which  includes  the  OCS  Console,  the  OCS 
disposables,  and  the  OCS  solution  additives.  We  also  received  the  recertification  of  the  CE  Mark  in  September  2022  for  the  OCS  Liver  Console  and 
disposables. We received the CE Mark for the OCS Liver combined with our solution additives under the MDR in May 2023, with an effective date of 
April 2023. In addition, we received a Class II Medical Device License from Health Canada for our OCS Liver combined with our solution additives in 
October 2023 to complement our existing Health Canada licenses for OCS Heart and OCS Lung.

We expect that our revenue will increase over the long term as a result of the continued growth of the NOP in the United States. We also expect that 
our revenue will increase over the long term as a result of anticipated growth in non-U.S. sales if national healthcare systems begin to reimburse transplant 
centers for the use of the OCS, if transplant centers utilize the OCS in more transplant cases and if more transplant centers adopt the OCS in their programs. 

Cost of Revenue, Gross Profit and Gross Margin 

Cost  of  net  product  revenue  consists  of  costs  of  components  of  our  OCS  Consoles  and  disposable  sets,  costs  of  direct  materials,  labor  and  the 
manufacturing overhead that directly supports production and depreciation of OCS Consoles. Included in the cost of OCS disposable sets are the costs of 
our OCS Lung, OCS Heart and OCS Liver Solutions. Cost of service revenue primarily consists of labor and overhead that directly support organ retrieval 
and OCS organ management services and transportation and logistics costs, including labor costs for pilots, aircraft depreciation, aircraft costs, fuel, crew 
travel,  maintenance  and  third-party  flight  costs  and  ground  transportation  that  support  organ  delivery.  For  the  year  ended  December  31,  2023,  cost  of 
service revenue also included approximately $4.4 million of costs related to charter flight and aircraft management and related services and flight school 
training revenue, from Summit's legacy operations, which is unrelated to the NOP and organ transplant.

Gross profit is the amount by which revenue exceeds cost of revenue in each reporting period and gross margin is gross profit divided by revenue. 
Our  overall  gross  margin  will  be  impacted  by  the  relative  mix  of  product  and  service  revenue,  as  product  and  service  revenue  have  different  margin 
profiles, and we expect our overall gross margin will decrease as service revenue increases as a proportion of overall revenue. Product and service gross 
margins are also affected by a variety of factors, primarily production volumes, the cost of components and direct materials, manufacturing overhead costs, 
direct labor, the cost of services provided under the NOP and the selling price of our OCS products and NOP services. 

We expect that overall cost of revenue will increase or decrease in absolute dollars primarily as, and to the extent that, our revenue increases or 
decreases. We expect that the cost of net product revenue as a percentage of net product revenue will moderately decrease and gross margin and gross profit 
will moderately increase over the long term as our sales and production volumes increase and our cost per unit of our OCS disposable sets decreases due to 
economies  of  scale,  our  product  enhancements  and  improved  manufacturing  efficiency.  We  intend  to  use  our  design,  engineering  and  manufacturing 
capabilities to further advance and improve the efficiency of our manufacturing processes, which we believe will reduce costs and increase our product 
gross margin. We also expect to see modest improvements in the future in our services gross margin as we provide more services and the efficiency in 
provisioning of these services improves due to scale and experience. While we expect our gross margins to increase over the long term, they will likely 
fluctuate from quarter to quarter.

69

 
Operating Expenses 

Research, Development and Clinical Trials Expenses 

Research, development and clinical trials expenses consist primarily of costs incurred for our research activities, product development, hardware and 
software  engineering,  clinical  trials  to  continue  to  develop  clinical  evidence  of  our  products’  safety  and  effectiveness,  regulatory  expenses,  testing, 
consultant services and other costs associated with our OCS technology platform and OCS products, which include: 

•

•

•

•

•

employee-related  expenses,  including  salaries,  related  benefits  and  stock-based  compensation  expense  for  employees  engaged  in  research, 
hardware and software development, regulatory and clinical trial functions, and recruiting and temporary service fees related to such personnel; 

expenses  incurred  in  connection  with  the  clinical  trials  of  our  products,  including  under  agreements  with  third  parties,  such  as  consultants,
contractors and data management organizations; 

the cost of maintaining and improving our product designs, including the testing of materials and parts used in our products; 

laboratory supplies and research materials; and 

facilities, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities and insurance. 

We  expense  research,  development  and  clinical  trials  costs  as  incurred.  In  the  future,  we  expect  that  research,  development  and  clinical  trials 
expenses will increase over the long term due to ongoing product development and approval efforts. We expect to continue to perform activities related to 
obtaining  additional  regulatory  approvals  for  expanded  indications  in  the  United  States  and  other  served  geographies,  as  well  as  developing  the  next 
generation of our OCS technology platform.

Acquired In-Process Research and Development Expenses 

Acquired in-process research and development expenses, or IPR&D, consist of the acquisition value of transactions that do not qualify as a business 

combination and that do not have an alternative future use.

Selling, General and Administrative Expenses 

Selling, general and administrative expenses consist primarily of salaries and related costs, including stock-based compensation, for personnel in our 
commercial  team  and  personnel  in  executive,  marketing,  finance  and  administrative  functions,  and  recruiting  and  temporary  service  fees  for  such 
personnel.  Selling,  general  and  administrative  expenses  also  include  direct  and  allocated  facility-related  costs,  costs  to  facilitate  the  NOP,  promotional 
activities, marketing, conferences and trade show costs as well as professional fees for legal, patent, consulting, investor and public relations, accounting 
and audit services and amortization of sales and marketing-related intangible assets. We expect to continue to increase headcount in our commercial team 
and increase marketing efforts as we continue to grow commercial sales of our OCS products in both U.S. and select non-U.S. markets. 

We  expect  that  our  selling,  general  and  administrative  expenses  will  increase  over  the  long  term  as  we  increase  our  headcount  to  support  the 

expected continued sales growth of our OCS products and our NOP. 

Other Income (Expense) 

Interest Expense 

Interest expense consists of interest expense associated with outstanding borrowings under our loan agreements as well as the amortization of debt 
discounts associated with such agreements. In July 2022, we entered into a credit agreement with Canadian Imperial Bank of Commerce, or CIBC, under 
which  we  borrowed  $60.0  million.  At  that  time,  we  repaid  the  remaining  $35.0  million  of  principal  that  had  been  outstanding  under  our  prior  credit 
agreement with OrbiMed Royalty Opportunities II, LP, or OrbiMed. In May 2023, we issued and sold $460.0 million in aggregate principal amount of our 
1.50% Convertible Senior Notes due 2028. 

70

 
Other Income (Expense), Net 

Other income (expense), net includes interest income, realized and unrealized foreign currency transaction gains and losses and other non-operating 
income and expense items unrelated to our core operations. Interest income consists of interest earned on our invested cash balances. Foreign currency 
transaction gains and losses result from intercompany transactions as well as transactions with customers or vendors denominated in currencies other than 
the functional currency of the legal entity in which the transaction is recorded.

We also had service revenue unrelated to OCS transplant of $4.9 million, including $3.0 million of charter flight and aircraft management and 

related services and $1.9 million of flight school training revenue, from Summit's legacy operations for the year ended December 31, 2023.

Revenue from customers in the United States related to OCS transplant was $221.3 million in the year ended December 31, 2023 and increased by 
$137.3 million compared to the year ended December 31, 2022, primarily due to higher sales volumes of our OCS Liver and OCS Heart disposable sets. 
Revenue for each organ in the table above includes net product revenue from sales of disposable sets as well as service revenue for organ retrieval, OCS 
organ  management  and  logistics  services  under  the  NOP  in  the  United  States.  Establishing  the  NOP,  which  launched  in  late  2021,  has  allowed  us  to 
broaden  our  customer  base  and  increase  utilization  of  the  OCS  in  organ  transplantation.  Significantly  all  of  our  customers  in  the  United  States  now 
participate in the NOP. By adding logistics to our NOP offering, we have been able to further increase product and service revenue.

Revenue from customers outside the United States was $15.4 million in the year ended December 31, 2023 and increased by $6.0 million compared 
to the year ended December 31, 2022. Revenue outside of the United States increased for the year ended December 31, 2023 compared to the year ended 
December 31, 2022 due primarily to increased sales volume of OCS Heart disposable sets. 

Cost of Revenue, Gross Profit and Gross Margin 

Cost of net product revenue increased by $24.0 million in the year ended December 31, 2023 compared to the year ended December 31, 2022. Cost 
of service revenue increased by $35.3 million in the year ended December 31, 2023 compared to the year ended December 31, 2022 as we expanded and 
increased utilization of the NOP. Gross profit increased by $88.8 million in the year ended December 31, 2023 compared to the year ended December 31, 
2022. Cost of service revenue included approximately $4.4 million of costs related to charter flight and aircraft management and related services and flight 
school training revenue, from Summit's legacy operations, which is unrelated to the NOP and organ transplant. 

Overall gross margin was 64% and 70% for the years ended December 31, 2023 and 2022, respectively. The decrease in gross margin from 2022 to 
2023 was driven primarily by an increase in service revenue, which has a lower gross margin than product revenue. Gross margin from net product revenue 
was  77%  and  79%  for  the  years  ended  December  31,  2023  and  2022,  respectively.  The  decrease  in  gross  margin  was  primarily  a  result  of  increasing 
manufacturing capacity and increased costs of certain parts. Gross margin from service revenue was 29% and 21% for the years ended December 31, 2023 
and 2022, respectively, and consisted primarily of organ retrieval, OCS organ management and logistics services under our NOP. Service revenue gross 
margin during the year ended December 31, 2023, included the introduction of transportation and logistics services and the purchase and integration of 
Summit  in  the  third  quarter  of  2023.  Service  revenue  gross  margin  during  the  year  ended  December  31,  2022  included  our  initial  launch  of  the  NOP 
program and did not include a full period of our NOP service offering.

million  in  the  year  ended  December  31,  2023.  Personnel  related  costs  increased  by  $5.7  million  primarily  due  to  increased  headcount  to  support 
development efforts for our next generation OCS program and overall compensation increases. Personnel related costs included stock-based compensation 
expense of $2.8 million and $1.5 million for the years ended December 31, 2023 and 2022, respectively. Laboratory supplies and research materials costs 
increased by $2.5 million from the year ended December 31, 2022 to the year ended December 31, 2023 primarily due to our increased need for supplies 
and materials used for development of our next generation OCS. Facility related and other costs increased by $1.2 million from the year ended December 
31, 2022 to the year ended December 31, 2023 due primarily to the increased costs of supporting a larger group of research and development personnel and 
their development efforts. Clinical trial costs decreased by $0.7 million due to the timing of pre-approval and post-approval clinical trials.

Total selling, general and administrative expenses increased by $49.7 million from $69.9 million in the year ended December 31, 2022 to $119.6 
million in the year ended December 31, 2023 due to increases in personnel related costs, professional and consultant fees, NOP support costs and facility 
related and other costs. Personnel related costs increased by $32.2 million primarily due to the continued expansion of our team to support the growth in 
our business, as well as an increase in stock-based compensation expense of $7.8 million, due primarily to additional grants to new and existing employees. 
Professional  and  consultant  fees  increased  by  $9.4  million  due  primarily  to  increased  consulting,  legal  and  audit  fees  related  to  the  business  growth. 
Professional and consultant fees also included transaction costs related to our acquisitions of $2.0 million. The increase in NOP support of $3.5 million was 
due to the continued growth and expansion of our NOP, including our national command and dispatch center. Facility related and other costs increased by 
$4.8 million due primarily to increased facilities costs and depreciation and amortization expense due to the growth in our business.

Other Income (Expense)

Interest Expense 

Interest expense was $10.8 million and $3.7 million for the years ending December 31, 2023 and 2022, respectively. The increase was due primarily 
to interest expense for our $460.0 million principal amount of the Notes, which were issued in May 2023. Interest expense also increased due to an increase 
in the principal amount of the CIBC loan outstanding compared to the principal that had been outstanding under our prior credit agreement with OrbiMed, 
partially offset by the lower average interest rate for our indebtedness under the CIBC Credit Agreement.

Other Income (Expense), Net 

Other  income  (expense),  net  for  the  years  ended  December  31,  2023  and  2022  included  interest  income  of  $12.5  million  and  $0.9  million, 
respectively, from interest earned on invested cash balances, due to higher invested cash balance and to a lesser extent higher interest rates. Other income 
(expense), net included $0.3 million of realized and unrealized foreign currency transactions gains during the year ended December 31, 2023. Other income 
(expense),  net  included  $1.3  million  of  realized  and  unrealized  foreign  currency  transactions  losses  during  the  year  ended  December  31,  2022.  Other 
expense, net for the year ending December 31, 2022 also included a loss on extinguishment of debt of $0.6 million.

(Provision) Benefit for Income Taxes 

We recorded a tax benefit of $1.7 million for the year ended December 31, 2023 for the release of a portion of our valuation allowance related to the 

net deferred tax liabilities recorded in purchase accounting. As part of the allocation of the purchase price of Summit, we recorded deferred tax liabilities 
for the differences between the fair value recognized in purchase accounting and the tax basis of property, plant and equipment and intangible assets. The 
net deferred tax liability is a source of income to support the recognition of a portion of our existing deferred tax assets. Therefore, we released the same 
amount of our valuation allowance. We maintain a valuation allowance on our overall net deferred tax asset as we deem it more likely than not that the net 
deferred tax asset will not be realized.

Comparison of the Years Ended December 31, 2022 and 2021

For a discussion of our results of operations for the year ended December 31, 2022 as compared to the year ended December 31, 2021, see Item 7. 
Management’s Discussion and Analysis of Financial Condition and Results of Operations—Components of Our Results of Operations—Comparison of the 
Years Ended December 31, 2022 and 2021 included in our Annual Report on Form 10-K for the year ended December 31, 2022.

Liquidity and Capital Resources 

Since  our  inception,  we  have  incurred  significant  annual  operating  losses.  To  date,  we  have  funded  our  operations  primarily  with  proceeds  from
borrowings  under  loan  agreements,  proceeds  from  the  issuance  of  our  convertible  senior  notes,  proceeds  from  the  sale  of  common  stock  in  our  public 
offerings  and  revenue  from  clinical  trials  and  commercial  sales  of  our  OCS  products  and  NOP  services.  On  May  11,  2023,  we  issued  $460.0  million 
aggregate principal amount of the Notes, in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The total 
net proceeds from the sale of the Notes, after deducting debt issuance costs of $14.6 million, and purchases of capped calls of $52.1 million, were $393.3 
million. At December 31, 2023, our principal source of liquidity was cash of $394.8 million.

During the year ended December 31, 2023, operating activities used $13.0 million of cash, primarily resulting from our net loss of $25.0 million and 
net cash used by changes in our operating assets and liabilities of $44.3 million, partially offset by net non-cash charges of $56.3 million, which included an 
IPR&D charge of $27.2 million. Net cash used by changes in our operating assets and liabilities for the year ended December 31, 2023 consisted primarily 
of an increase in accounts receivable of $33.8 million, an increase in inventory of $28.1 million and an increase in prepaid expenses and other current assets 
of $2.1 million, partially offset by an increase in accounts payable and accrued expenses and other current liabilities of $21.2 million.

During the year ended December 31, 2022, operating activities used $45.8 million of cash, primarily resulting from our net loss of $36.2 million and 
net cash used by changes in our operating assets and liabilities of $26.8 million, partially offset by net non-cash charges of $17.2 million. Net cash used by 
changes in our operating assets and liabilities for the year ended December 31, 2022 consisted primarily of an increase in accounts receivable of $21.7 
million and an increase in inventory of $8.0 million, partially offset by a decrease in prepaid expenses of $2.5 million.

Changes  in  accounts  receivable,  inventory,  prepaid  expenses  and  other  current  assets,  accounts  payable,  and  accrued  expenses  and  other  current 

liabilities in each reporting period are generally due to growth in our business and timing of invoices and payments.

Investing Activities 

During  the  year  ended  December  31,  2023,  net  cash  used  in  investing  activities  of  $194.0  million  consisted  of  purchases  of  property,  plant  and 
equipment of $151.8 million, including $141.9 million of transplant-related aircraft purchases, the purchase of IPR&D assets from BTL for $27.2 million 
and the purchase of Summit for $14.9 million, net of cash received.

During the year ended December 31, 2022, net cash provided by investing activities of $54.5 million consisted of proceeds from sales and maturities 
of marketable securities of $76.9 million, partially offset by $10.5 million in purchases of marketable securities and $11.9 million in purchases of property 
and equipment.

Financing Activities 

During the year ended December 31, 2023, net cash provided by financing activities of $400.4 million consisted of net proceeds from the issuance 
of our Notes of $445.4 million, partially offset by payments of $52.1 million for associated capped calls, proceeds from the issuance of common stock upon 
exercise of stock options of $6.2 million and proceeds from the issuance of common stock in connection with the 2019 Employee Stock Purchase Plan of 
$1.0 million.

During the year ended December 31, 2022, net cash provided by financing activities of $167.9 million consisted of net proceeds from our public 
offering in August 2022 of $139.9 million, net proceeds from the issuance of long-term debt of $58.5 million, proceeds from the issuance of common stock 
upon exercise of stock options of $4.7 million, proceeds from the issuance of common stock in connection with the 2019 Employee Stock Purchase Plan of 
$0.5 million and proceeds from the issuance of common stock upon exercise of warrants of $0.4 million, partially offset by the repayments of long-term 
debt of $36.1 million.

Condition  and  Results  of  Operations—Liquidity  and  Capital  Resources—Cash  Flows  included  in  our  Annual  Report  on  Form  10-K  for  the  year  ended 
December 31, 2022.

Convertible Senior Notes 

On  May  11,  2023,  we  issued  $460.0  million  aggregate  principal  amount  of  the  Notes,  in  a  private  placement  to  qualified  institutional  buyers 
pursuant to Rule 144A under the Securities Act, pursuant to an indenture dated May 11, 2023, by and between us and U.S. Bank Trust Company, National 
Association, or the Indenture.

The initial conversion price of the Notes is approximately $94.00 per share of common stock, which represents a premium of approximately 32.5% 
over the closing price of our common stock on May 8, 2023. The Notes will mature on June 1, 2028, unless earlier repurchased, redeemed or converted. We 
used $52.1 million of the proceeds from the sale of the Notes to fund the cost of entering into capped call transactions, described below. The proceeds from 
the issuance of the Notes were approximately $393.3 million, net of capped call transaction costs of $52.1 million and initial purchaser discounts and other 
debt issuance costs totaling $14.6 million. The Notes bear interest at a rate of 1.50% per year and interest is payable semiannually in arrears on June 1 and 
December 1 of each year. The initial conversion rate is 10.6388 shares of common stock per $1,000 principal amount of the Notes, which represents an 
initial  conversion  price  of  approximately  $94.00  per  share  of  common  stock.  The  conversion  rate  and  conversion  price  are  subject  to  customary 
adjustments upon the occurrence of certain events as described in the Indenture.

Before  March  1,  2028,  noteholders  have  the  right  to  convert  their  Notes  only  upon  the  occurrence  of  certain  events,  including  certain  corporate 
events, and during the five business days immediately after any ten consecutive trading days in which the trading price per $1,000 principal amount of 
Notes is less than ninety eight percent (98%) of the as converted value. Additionally, the noteholder can convert their Notes during any calendar quarter 
(and only during such calendar quarter), commencing after the calendar quarter ending on September 30, 2023 but before March 1, 2028, provided the last 
reported sale price of the common stock for at least 20 trading days is greater than or equal to 130% of the conversion price during the 30 consecutive 
trading days ending on the last trading day of a calendar quarter. From and after March 1, 2028, noteholders may convert their Notes at any time at their 
election  until  the  close  of  business  on  the  second  scheduled  trading  day  immediately  before  the  maturity  date.  We  have  the  right  to  elect  to  settle 
conversions either in cash, shares or in a combination of cash and shares of our common stock. 

Prior to June 8, 2026, the Notes will not be redeemable. On or after June 8, 2026, we may redeem for cash all or any portion of the Notes (subject to 
the partial redemption limitation set forth in the Indenture), at our option, if the last reported sale price of our common stock has been at least 130% of the 
conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last 
trading  day  of  such  period)  ending  on,  and  including,  the  trading  day  immediately  preceding  the  date  on  which  we  provide  notice  of  redemption.  In 
addition, calling any Note for redemption will constitute a “Make-Whole Fundamental Change” (as defined in the Indenture) with respect to that Note, in 
which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for 
redemption.

Long-Term Debt

In July 2022, we entered into a credit agreement with CIBC as amended by the First Amendment to Credit Agreement, dated as of May 8, 2023, by 
and among the Company and CIBC, or the First Amendment, the Second Amendment to Credit Agreement, dated as of June 23, 2023, by and among the 
Company  and  CIBC,  or  the  Second  Amendment,  and  the  Third  Amendment  to  Credit  Agreement,  dated  as  of  November  9,  2023,  by  and  among  the 
Company and CIBC, or the Third Amendment, pursuant to which we borrowed $60.0 million, referred to herein as the CIBC Credit Agreement. We used 
proceeds of the CIBC Credit Agreement to repay all amounts due under our previously outstanding credit agreement with OrbiMed, which was entered into 
in June 2018.

76

 
On  May  8,  2023,  we  entered  into  the  First  Amendment,  which  among  other  items,  allowed  for  the  issuance  of  the  Notes  and  capped  call 
transactions. On June 23, 2023, we entered into the Second Amendment, which among other items, permits us to make acquisitions of equity or assets of 
another entity, subject to the conditions under the Second Amendment, including acquisitions, without further consent of CIBC, up to a maximum amount
of $50.0 million for the cash payable in connection with an individual acquisition and a maximum amount in aggregate of $150.0 million for the total cash 
consideration payable for all acquisitions made by us on or after June 23, 2023. The definition of consolidated adjusted EBITDA was also amended by the 
Second  Amendment  to  add  a  provision  for  the  pro  forma  effect  of  any  acquisitions  that  occur  during  the  period.  Additionally,  pursuant  to  the  Second 
Amendment,  we  and  CIBC  agreed  to  extend  the  start  of  the  principal  repayment  period  to  July  31,  2026,  on  which  date  we  are  obligated  to  begin 
repayment  of  the  term  loans  in  equal  monthly  installments  until  the  maturity  date  in  July  2027.  On  November  9,  2023,  we  entered  into  the  Third 
Amendment,  which,  among  other  items,  permits  us  to  make  acquisitions  of  equity  or  assets  of  another  entity,  subject  to  the  conditions  under  the  Third 
Amendment, without further consent of CIBC, for cash consideration in a maximum aggregate amount of $300.0 million for all such acquisitions made by 
the Company on or after November 9, 2023.

Borrowings under the CIBC Credit Agreement bear interest at an annual rate equal to either, at our option, (i) the secured overnight financing rate 
for an interest period selected by us, subject to a minimum of 1.50%, plus 2.0% or (ii) 1.0% plus the higher of a) the prime rate, subject to a minimum of 
4.0% or b) the Federal Funds Effective Rate, plus 0.5%. At our option, we may prepay borrowings outstanding under the CIBC Credit Agreement, subject 
to a prepayment fee of 2.0% of outstanding borrowings if paid prior to 12 months after the closing date, and 1.0% if paid after 12 months but prior to 24 
months after the closing date. All obligations under the CIBC Credit Agreement are guaranteed by us and each of our material subsidiaries. 

All  obligations  of  us  and  each  guarantor  are  secured  by  substantially  all  of  our  and  each  guarantor’s  assets,  including  their  intellectual  property, 
subject to certain exceptions. Under the CIBC Credit Agreement, we have agreed to customary representations and warranties, events of default and certain 
affirmative  and  negative  covenants  to  which  we  will  remain  subject  until  maturity.  The  financial  covenants  include,  among  other  covenants,  (x)  a 
requirement to maintain a minimum liquidity amount of the greater of either (i) the consolidated adjusted EBITDA loss (or gain) for the trailing four month 
period (only if EBITDA is negative) and (ii) $10.0 million, and (y) a requirement to maintain total net revenue of at least 75% of the level set forth in the 
total revenue plan presented to CIBC. As discussed above, the definition of consolidated adjusted EBITDA was amended to include the pro forma effect of 
acquisitions. The obligations under the CIBC Credit Agreement are subject to acceleration upon the occurrence of specified events of default, including 
payment  default,  change  in  control,  bankruptcy,  insolvency,  certain  defaults  under  other  material  debt,  certain  events  with  respect  to  governmental 
approvals (if such events could cause a material adverse change in our business), failure to comply with certain covenants and a material adverse change in 
our  business,  operations  or  financial  condition.  As  of  December  31,  2023,  we  were  in  compliance  with  all  covenants  of  the  CIBC  Credit  Agreement. 
During the continuance of an event of default, the interest rate per annum will be equal to the rate that would have otherwise been applicable at the time of 
the event of default plus 2.0%. If an event of default (other than certain events of bankruptcy or insolvency) occurs and is continuing, CIBC may declare all 
or  any  portion  of  the  outstanding  principal  amount  of  the  borrowings  plus  accrued  and  unpaid  interest  to  be  due  and  payable.  Upon  the  occurrence  of 
certain events of bankruptcy or insolvency, all of the outstanding principal amount of the borrowings plus accrued and unpaid interest will automatically 
become  due  and  payable.  In  addition,  we  may  be  required  to  prepay  outstanding  borrowings,  subject  to  certain  exceptions,  with  portions  of  net  cash 
proceeds of certain asset sales and certain casualty and condemnation events.

Funding Requirements

As  we  continue  to  pursue  and  increase  commercial  sales  of  our  OCS  products,  we  expect  our  costs  and  expenses  to  increase  in  the  future, 
particularly as we expand our commercial team, grow our NOP, scale our manufacturing and sterilization operations, continue research, development and 
clinical  trial  efforts,  seek  regulatory  approval  for  new  products  and  product  enhancements,  including  new  indications,  both  in  the  United  States  and  in 
select non-U.S. markets, and seek greater control of air and ground transport for our NOP. For example, if the demand for our products exceeds our existing 
manufacturing  and  sterilization  capacity,  our  ability  to  fulfill  orders  would  be  limited  until  we  have  sufficiently  expanded  such  operations.  In  addition, 
following the closing of our IPO, we have incurred and expect to continue to incur additional costs associated with operating as a public company. The 
timing and amount of our operating and capital expenditures will depend on many factors, including: 

•

•

the amount of product revenue generated by sales of our OCS Consoles, OCS disposable sets and other products that may be approved in the 
United States and select non-U.S. markets, revenue generated by our services, and growth of the NOP; 

the costs and expenses of expanding our U.S. and non-U.S. sales and marketing infrastructure and our manufacturing operations;

the cost of maintaining, replacing or acquiring additional fixed-wing aircraft;

the costs of preparing, filing and prosecuting patent applications and maintaining, enforcing and defending intellectual property-related claims; 
and 

the level of our selling, general and administrative expenses. 

We believe that our existing cash will enable us to fund our operating expenses, capital expenditure requirements, and debt service payments for at 

least 12 months following the filing of our annual report on Form 10-K. 

We may need to raise additional funding, which might not be available on favorable terms or at all. See “Item 1A. Risk Factors—Risks Related to 

Our Financial Position and Need for Additional Capital” in this Annual Report on Form 10-K. 

Material Contractual Obligations

Our  contractual  obligations  include  amounts  payable  as  principal  and  interest  payments  under  the  CIBC  Credit  Agreement.  As  of  December  31, 
2023, our outstanding principal balance was $60.0 million and is due in 2027. We estimate we will pay $4.5 million in interest payments during 2024. Our 
estimate of payments is based on an assumed rate of 7.3%, which was the interest rate in effect at December 31, 2023. 

On May 11, 2023, we issued $460.0 million aggregate principal amount of Notes due 2028. The Notes bear interest at a rate of 1.50% per year, 
payable semi-annually in arrears on June 1 and December 1 of each year. The Notes will mature on June 1, 2028, unless earlier converted, redeemed or 
repurchased.

We lease facilities under long-term non-cancelable operating leases that have a weighted average remaining lease term of 4.7 years as of December 
31, 2023. As of December 31, 2023, we had fixed lease payment obligations of $11.6 million, of which $2.6 million is payable during 2024. We also lease 
facilities under short-term leases, for which we expect to pay approximately $0.8 million in 2024 under existing leases.

In connection with our acquisition of Summit we acquired a construction contract for the completion of a commercial aircraft hangar at Bozeman 
Yellowstone  International  Airport  in  Bozeman,  Montana.  We  anticipate  we  will  incur  approximately  $3.0  million  to  $4.0  million  in  2024  to  complete 
construction of the hangar.

We  intend  to  acquire  additional  fixed-wing  aircraft  as  we  scale  our  fleet  of  aircraft.  During  the  year  ended  December  31,  2023,  we  acquired  11 
transplant-related fixed-wing aircraft with an aggregate purchase price of $141.9 million and we plan to acquire additional aircraft in 2024, including two 
aircraft purchased in January and February 2024.

In January 2021, we entered into an unconditional $9.5 million purchase commitment in the ordinary course of business, for goods with specified 
annual  minimum  quantities  to  be  purchased  through  December  2029.  The  contract  is  not  cancellable  without  penalty.  As  of  December  31,  2023,  our 
remaining purchase commitment is $7.0 million. 

We also enter into other contracts in the normal course of business with consulting firms, material suppliers and other third parties for clinical trials 

and testing and manufacturing services. These contracts do not contain minimum purchase commitments 

78

 
and are cancelable by us upon prior written notice. Payments due upon cancellation consist only of payments for services provided or expenses incurred, 
including noncancelable obligations of our service providers, up to the date of cancellation. These payments are not included in the discussion above as the 
amount and timing of such payments are not known.

Critical Accounting Policies and Significant Judgments and Estimates 

Our  consolidated  financial  statements  are  prepared  in  accordance  with  generally  accepted  accounting  principles  in  the  United  States.  The 
preparation  of  our  consolidated  financial  statements  and  related  disclosures  requires  us  to  make  estimates,  assumptions  and  judgments  that  affect  the 
reported  amounts  of  assets,  liabilities,  revenue,  costs  and  expenses,  and  related  disclosures.  We  evaluate  our  estimates  on  an  ongoing  basis.  Our  actual 
results may differ from these estimates under different assumptions or conditions. 

While our significant accounting policies are described in more detail in Note 2 to our consolidated financial statements included elsewhere in this
Annual  Report  on  Form  10-K,  we  believe  that  the  following  accounting  policies  are  those  most  critical  to  the  judgments  and  estimates  used  in  the 
preparation of our consolidated financial statements. 

Revenue Recognition 

We generate net product revenue primarily from sales of our single-use, organ-specific disposable sets used on our organ-specific OCS Consoles. To 
a lesser extent, we also generate revenue from the sale of OCS Consoles to customers and the implied rental of OCS Consoles loaned to customers at no 
charge. For each new transplant procedure, customers purchase an additional OCS disposable set for use on the customer’s existing organ-specific OCS 
Console. We also generate service revenue by providing outsourced organ retrieval, OCS organ management and logistics services under our NOP in the 
United States.

We recognize revenue from sales to customers applying the following five steps: (1) identification of the contract, or contracts, with a customer, (2) 
identification  of  the  performance  obligations  in  the  contract,  (3)  determination  of  the  transaction  price,  (4)  allocation  of  the  transaction  price  to  the 
performance obligations in the contract, and (5) recognition of revenue when, or as, performance obligations are satisfied. 

Substantially all of our customer contracts have multiple-performance obligations that contain deliverables consisting of OCS Perfusion Sets and 
OCS Solutions. Customer contract deliverables may also include organ retrieval, OCS organ management and logistics services under our NOP or an OCS 
Console, whether sold or loaned to the customer. We evaluate each promise within a multiple-performance obligation arrangement to determine whether it 
represents a distinct performance obligation. The primary performance obligations in our customer arrangements from which we derive revenue are the 
OCS Perfusion Sets, the OCS Solutions, the OCS Console, organ retrieval services, OCS organ management services and organ transportation logistics. 

When a customer order includes an OCS Console, we have determined that customer training and the equipment set-up of the OCS Console, each 
performed by us, are not distinct because they are not sold on a standalone basis and can only be performed by us in conjunction with a sale or loan of our 
OCS  Console.  In  addition,  we  have  determined  that  the  OCS  Console  itself  is  not  distinct  because  the  customer  cannot  benefit  from  the  OCS  Console 
without the training and equipment set-up having been completed. As a result, when the order includes an OCS Console, we have concluded that training, 
OCS  Console  equipment  set-up,  and  the  OCS  Console  itself  are  highly  interdependent  and  represent  a  single,  combined  performance  obligation.  We 
recognize  revenue  from  the  single,  combined  performance  obligation  only  once  the  OCS  Console  has  arrived  at  the  customer  site  and  the  training  and 
equipment set-up have been completed by us. 

Customer orders may include the loan of an OCS Console as well as OCS disposable sets used in each transplant procedure. When we loan the OCS 
Console to the customer, we retain title to the console at all times and do not require minimum purchase commitments from the customer related to any 
OCS products. In such cases, we invoice the customer for OCS disposable sets based on customer orders received for each new transplant procedure and 
the  prices  set  forth  in  the  customer  agreement.  Over  time,  we  typically  recover  the  cost  of  the  loaned  OCS  Console  through  the  customer’s  continued 
purchasing and use of additional OCS disposable sets. For these reasons, we have determined that part of the arrangement consideration for the disposable 
set is an implied rental payment for use of the OCS Console. Therefore, we allocate the arrangement consideration between the lease deliverables (i.e., the 
OCS  Console)  and  non-lease  deliverables  (i.e.,  the  OCS  disposable  sets)  based  on  the  relative  estimated  standalone  selling  price  of  each  distinct 
performance obligation. To date, the amounts allocated to lease deliverables have been insignificant. 

79

 
Revenue  from  sales  to  customers  of  OCS  Perfusion  Sets,  OCS  Solutions  and  OCS  Consoles  is  classified  as  net  product  revenue  in  the  our 
consolidated statements of operations. Revenue from sales to customers of organ retrieval, OCS organ management services and organ transportation is 
classified as service revenue in our consolidated statements of operations. 

Revenue  is  recognized  when  control  is  transferred  to  the  customer  in  an  amount  that  reflects  the  consideration  we  expect  to  be  entitled  to  in 
exchange for the product or services. When a customer order includes disposable sets and organ retrieval, OCS organ management or logistics services, we 
have  determined  that  the  disposable  sets  and  services  constitute  separate  performance  obligations  and  we  recognize  revenue  as  the  disposable  sets  and 
services are each delivered to the customer. 

Payments Made to Customers 

Under some of our customer clinical trial agreements, we made payments to our customers for reimbursements of clinical trial materials and for 
specified  clinical  documentation  related  to  their  use  of  our  OCS  products.  We  also  make  payments  to  customers  involved  in  post-approval  studies  for 
information  related  to  the  transplant  procedures  performed.  We  determine  the  appropriate  accounting  treatments  for  these  payments  depending  on  the 
nature of the payment and whether they are for distinct goods or services. 

Other Revenue Considerations

We  only  include  estimated  variable  amounts  in  the  transaction  price  to  the  extent  it  is  probable  that  a  significant  reversal  of  cumulative  revenue 
recognized will not occur when the uncertainty associated with the variable consideration is resolved. We do not assess whether promised goods or services 
are  performance  obligations  if  they  are  deemed  immaterial  in  the  context  of  the  contract  with  the  customer.  Additionally,  we  do  not  assess  whether  a 
contract has a significant financing component if the expectation at contract inception is that the period between payment by the customer and the transfer 
of the promised goods or services to the customer will be one year or less. Revenue is reported net of taxes.

Valuation of Inventory 

We  value  inventory  at  the  lower  of  cost  or  net  realizable  value,  with  cost  computed  using  the  first-in,  first-out  method.  We  regularly  review 
inventory  quantities  on-hand  for  excess  and  obsolete  inventory  and,  when  circumstances  indicate,  record  charges  to  write  down  inventories  to  their 
estimated  net  realizable  value,  after  evaluating  historical  sales,  future  demand,  market  conditions  and  expected  product  life  cycles.  Such  charges  are 
classified as cost of revenue in our consolidated statements of operations. Any write-down of inventory to net realizable value creates a new cost basis. The 
reserve for excess and obsolete inventory was $0.8 million and $0.3 million as of December 31, 2023 and 2022, respectively.

At the end of each reporting period, we assess whether losses should be accrued on long-term manufacturing purchase commitments in accordance 
with ASC 330, Inventory, which requires that losses that are expected to arise from firm, noncancelable and unhedged commitments for the future purchase 
of  inventory,  measured  in  the  same  way  as  inventory  losses,  should  be  recognized  in  the  current  period  in  the  statements  of  operations  unless  they  are 
deemed recoverable through firm sales contacts or when there are other circumstances that reasonably assure continuing sales without price decline. As of 
the end of each reporting period presented in our consolidated financial statements included elsewhere in this Annual Report on Form 10-K, we did not 
identify any potential losses arising from remaining future purchase commitments as compared to estimated future customer sales through the remainder of 
the term of the manufacturing purchase commitment and, as a result, did not recognize in a current period any loss provision for future-period remaining 
purchase commitments. 

Business Combinations and Fair Value Estimates 

In  determining  whether  an  acquisition  should  be  accounted  for  as  a  business  combination  or  asset  acquisition,  we  first  determine  whether 
substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this is 
the  case,  the  single  identifiable  asset  or  the  group  of  similar  assets  is  not  deemed  to  be  a  business  and  the  acquisition  is  accounted  for  as  an  asset 
acquisition. If this is not the case, we then further evaluate whether the acquisition includes, at a minimum, an input and a substantive process that together 
significantly contribute to the ability to create outputs. If so, we conclude that the acquisition is a business and account for it as a business combination.

Determining the fair value of assets acquired and liabilities assumed in a business combination is judgmental in nature and can involve the use of 
significant  estimates  and  assumptions.  Fair  value  and  useful  life  determinations  are  based  on,  among  other  things,  valuations  that  use  information  and 
assumptions provided by management, which consider management’s best estimates of inputs and assumptions that a market participant would use. Actual 
results  may  vary  from  these  estimates  and  may  result  in  adjustments  to  goodwill  and  acquisition  date  fair  values  of  assets  and  liabilities  during  a 
measurement period or upon a final 

80

 
determination  of  asset  and  liability  fair  values,  whichever  comes  first.  Adjustments  to  fair  values  of  assets  and  liabilities  made  after  the  end  of  the 
measurement period are recorded within operating results.

Recently Issued Accounting Pronouncements 

A description of recently issued accounting pronouncements that may potentially impact our financial position, results of operations or cash flows is 

disclosed in Note 2 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. 

Item 7A. Quantitative and Qualitative Disclosures About Market Risk. 

We are exposed to changes in interest rates and foreign currency exchange rates because we finance certain operations through variable rate debt 
instruments  and  denominate  our  transactions  in  a  variety  of  foreign  currencies.  Changes  in  these  rates  may  have  an  impact  on  future  cash  flow  and 
earnings. We manage these risks through normal operating and financing activities. 

Foreign Currency Exchange Risk 

Our  foreign  currency  transaction  exposure  results  primarily  from  intercompany  transactions  and  transactions  with  customers  or  vendors 
denominated in currencies other than the functional currency of the legal entity in which the transaction is recorded by us. Assets and liabilities arising 
from  such  transactions  are  translated  into  the  legal  entity’s  functional  currency  using  the  period-end  exchange  rates.  Foreign  currency  transaction  gains 
(losses) are included in the consolidated statements of operations as a component of other income (expense). We recognized foreign currency transaction 
gains of $0.3 million during the year ended December 31, 2023. 

Foreign currency translation exposure results from the translation of the financial statements of our subsidiaries whose functional currency is not the 
U.S. dollar into U.S. dollars for consolidated reporting purposes. Assets and liabilities of these subsidiaries are translated into U.S. dollars using the period-
end exchange rates, and income and expense items are translated into U.S. dollars using average exchange rates in effect during each period. The effects of 
these foreign currency translation adjustments are included in accumulated other comprehensive loss, a separate component of stockholders’ equity on our 
consolidated balance sheets. We recorded a foreign currency translation gain of less than $0.1 million during the year ended December 31, 2023. 

For  the  year  ended  December  31,  2023,  5%  of  our  revenue  and  2%  of  our  operating  costs  and  expenses  were  generated  by  subsidiaries  whose 

functional currency is not the U.S. dollar and therefore are subject to foreign currency exposure. 

Currently, our largest foreign currency exposure is that with respect to the Euro. We believe that a 10% change in the exchange rate between the 
U.S.  dollar  and  Euro  would  not  materially  impact  our  operating  results  or  financial  position.  We  have  experienced  and  we  will  continue  to  experience 
fluctuations in our net loss as a result of revaluing our assets and liabilities that are not denominated in the functional currency of the entity that recorded 
the asset or liability. At this time, we do not hedge our foreign currency risk. 

Interest Rate Sensitivity 

In July 2022, we entered into our CIBC Credit Agreement with CIBC. Borrowings under the CIBC Credit Agreement bear interest at an annual rate 
equal to either, at our option, (i) the secured overnight financing rate for an interest period selected by us, subject to a minimum of 1.5%, plus 2.0% or (ii) 
1.0% plus the higher of a) the prime rate, subject to a minimum of 4.0% or b) the Federal Funds Effective Rate, plus 0.5%. As of December 31, 2023 
borrowings  outstanding  under  the  CIBC  Credit  Agreement  totaled  $60.0  million  and  the  interest  rate  applicable  to  such  borrowings  was  7.3%.  An 
immediate 10% change in the Federal Funds Effective Rate would not have a material impact on our debt-related obligations, financial position or results 
of operations. 

In May 2023, we issued the Notes with an aggregate principal amount of $460.0 million. In connection with the issuance of the Notes, we entered 
into privately negotiated capped call transactions with certain counterparties. The capped calls are expected generally to offset the potential dilution to our 
common stock as a result of any conversion of the Notes. The Notes have a fixed annual interest rate of 1.50%. Accordingly, we do not have interest rate 
exposure on the Notes.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 To the Board of Directors and Stockholders of TransMedics Group, Inc. 

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of TransMedics Group, Inc. and its subsidiaries (the “Company”) as of December 31, 2023 
and 2022, and the related consolidated statements of operations, of comprehensive loss, of stockholders’ equity and of cash flows for each of the three 
years in the period ended December 31, 2023, including the related notes (collectively referred to as the “consolidated financial statements”). We also have 
audited the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated 
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of 
December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 in 
conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material 
respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated 
Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, 
and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control Over 
Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the 
Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting 
Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities 
laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable 
assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective 
internal control over financial reporting was maintained in all material respects.  

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial 
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, 
evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used 
and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal 
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing 
such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As described in Management’s Annual Report on Internal Control over Financial Reporting, management has excluded Summit Aviation, Inc. from its 
assessment of internal control over financial reporting as of December 31, 2023 because it was acquired by the Company in a purchase business 
combination during 2023. We have also excluded Summit Aviation, Inc. from our audit of internal control over financial reporting. Summit Aviation, Inc. is 
a wholly-owned subsidiary whose total assets and total revenues excluded from management’s assessment and our audit of internal control over financial 
reporting represent 2% and 2%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2023.

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly 
reflect the transactions and 

83

 
 
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 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.

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.

Critical Audit Matters

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

Revenue Recognition 

As described in Note 2 to the consolidated financial statements, the Company recorded $241.6 million in total revenues for the year ended December 31, 
2023. The Company generates product revenue, from sales of its single-use, organ-specific disposable sets (i.e., its organ-specific OCS Perfusion Sets sold 
together with its organ-specific OCS Solutions) used on its organ-specific OCS Consoles, each being a component of the Company’s Organ Care System 
(OCS) products, and service revenue, by providing outsourced organ retrieval, OCS organ management and logistics services under the Company’s 
National OCS Program. Substantially all of the Company’s customer contracts have multiple-performance obligations. Deliverables consist of OCS 
Perfusion Sets and OCS Solutions. In some of those customer contracts, the deliverables also include an OCS Console, whether sold or loaned to the 
customer. Management evaluates each promise within a multiple-performance obligation arrangement to determine whether it represents a distinct 
performance obligation. Management has concluded that training, OCS Console equipment set-up, and the OCS Console itself are highly interdependent 
and represent a single, combined performance obligation. Revenue is recognized when control of the OCS product or products is transferred to the 
customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for the product or products. Control is transferred 
for the OCS products typically only after the product has arrived at the customer site and, in addition for OCS Consoles, the training and equipment set-up 
have been completed by the Company. Additionally, under the National OCS program, service deliverables available to customers include organ retrieval, 
OCS organ management, and transportation logistics which are distinct performance obligations and are recognized as service revenue when the services 
occur. 

The principal considerations for our determination that performing procedures relating to revenue recognition is a critical audit matter are the high degree 
of auditor effort in performing procedures and in evaluating audit evidence related to management’s determination of the point in time when control of the 
OCS product or products is transferred to the customer or services are performed and revenue is recognized. 

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated 
financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process, including controls over the 
existence and point in time when control is transferred to the customer. These procedures also included, among others, evaluating, for a sample of 
transactions, the existence of transactions recognized as revenue, as well as evaluating the appropriate timing of revenue recognition by obtaining and 
inspecting customer purchase orders and, where applicable, invoices, customer agreements, shipping documents, completion of services documents and 
cash receipts from customers.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1.

Nature of the Business and Basis of Presentation 

TransMedics  Group,  Inc.  (“TransMedics  Group”  and,  together  with  its  consolidated  subsidiaries,  the  “Company”)  was  incorporated  in  the 
Commonwealth  of  Massachusetts  in  October  2018.  TransMedics,  Inc.  (“TransMedics”),  an  operating  company  and  wholly  owned  subsidiary  of 
TransMedics  Group,  was  incorporated  in  the  State  of  Delaware  in  August  1998.  The  Company  is  a  commercial-stage  medical  technology  company 
transforming organ transplant therapy for end-stage organ failure patients across multiple disease states. The Company developed the Organ Care System 
(“OCS”) to replace a decades-old standard of care. The OCS represents a paradigm shift that transforms organ preservation for transplantation from a static 
state to a dynamic environment that enables new capabilities, including organ optimization and assessment. The Company’s OCS technology replicates 
many  aspects  of  the  organ’s  natural  living  and  functioning  environment  outside  of  the  human  body.  The  Company  also  developed  its  National  OCS 
Program  (“NOP”),  an  innovative  turnkey  solution  to  provide  outsourced  organ  retrieval,  OCS  organ  management  and  logistics  services,  to  provide 
transplant  programs  in  the  United  States  with  a  more  efficient  process  to  procure  donor  organs  with  the  OCS.  Our  logistics  services  include  aviation 
transportation, ground transportation and other coordination activity.

On August 16, 2023, the Company acquired Summit Aviation, Inc. and Northside Property Group, LLC (together “Summit”). Summit was a charter 
flight  operator  based  in  Bozeman,  Montana.  The  acquisition  enabled  TransMedics  to  add  aviation  transportation  services  to  its  NOP  and  become  a 
comprehensive national provider of donor organ retrieval and delivery in the United States.

The  accompanying  consolidated  financial  statements  have  been  prepared  on  the  basis  of  continuity  of  operations,  realization  of  assets  and  the 
satisfaction of liabilities and commitments in the ordinary course of business. The Company has incurred recurring annual losses since inception, including 
a net loss of $25.0 million for the year ended December 31, 2023. As of December 31, 2023, the Company had an accumulated deficit of $503.7 million. 
The Company believes that its existing cash of $394.8 million as of December 31, 2023 will be sufficient to fund its operations, capital expenditures, and 
debt service payments for at least the next 12 months following the filing of this Annual Report on Form 10-K. The Company may need to seek additional 
funding through equity financings, debt financings or strategic alliances. The Company may not be able to obtain financing on acceptable terms, or at all, 
and the terms of any financing may adversely affect the holdings or the rights of the Company’s shareholders. If the Company is unable to obtain funding 
when  needed,  the  Company  will  be  required  to  delay,  reduce  or  eliminate  some  or  all  of  its  research  and  development  programs,  product  expansion  or 
commercialization efforts, or the Company may be unable to continue operations.

The  Company  is  subject  to  risks  and  uncertainties  common  to  companies  in  the  medical  device  industry  and  of  similar  size,  including,  but  not 
limited to, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance 
with  government  regulations,  uncertainty  of  market  acceptance  of  products,  and  the  need  to  obtain  additional  financing  to  fund  operations.  Products 
currently under development will require additional research and development efforts, including additional clinical testing and regulatory approval, prior to 
commercialization.  These  efforts  require  additional  capital,  adequate  personnel,  infrastructure  and  extensive  compliance-reporting  capabilities.  The 
Company’s  research  and  development  may  not  be  successfully  completed,  adequate  protection  for  the  Company’s  technology  may  not  be  obtained,  the 
Company may not obtain necessary government regulatory approval on its expected timeline or at all, and approved products may not prove commercially 
viable. The Company operates in an environment of rapid change in technology and competition.

The  Company’s  consolidated  financial  statements  have  been  prepared  in  conformity  with  accounting  principles  generally  accepted  in  the  United 
States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting 
Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). The accompanying 
consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have 
been eliminated in consolidation.

2.

Summary of Significant Accounting Policies 

Use of Estimates 

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported 
amounts  of  assets  and  liabilities,  the  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial  statements,  and  the  reported  amounts  of 
revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these consolidated financial statements include, but 
are  not  limited  to,  revenue  recognition,  the  valuation  of  inventory,  the  valuation  of  assets  acquired  and  liabilities  assumed  in  business  combinations, 
including acquired intangible assets and the resulting goodwill, and the valuation of stock-based awards. The Company bases its estimates on historical 
experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, 
management evaluates its estimates as there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which 
they become known. As of the date of issuance of these consolidated financial statements, the Company is not aware of any specific event or circumstance 
that would require the Company to update estimates, judgments or revise the carrying value of any assets or liabilities. Actual results may differ from those 
estimates or assumptions. 

Risk of Concentrations of Credit, Significant Customers and Significant Suppliers 

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and accounts receivable. The 
Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. As of 
December 31, 2023 and 2022, the Company had no allowance for credit losses.

Significant customers are those that accounted for 10% or more of the Company’s revenue or accounts receivable. For the year ended December 31, 
2023,  no  customer  accounted  for  more  than  10%  of  revenue.  For  the  years  ended  December  31,  2022  and  2021,  one  customer  accounted  for  14%  of 
revenue and one customer accounted for 11% of revenue, respectively. As of December 31, 2023 and 2022, no customer accounted for 10% or more of 
accounts receivable. 

Certain of the components and subassemblies included in the Company’s products are obtained from a sole source, a single source or a limited group
of  suppliers,  as  are  sterilization  services.  Although  the  Company  seeks  to  reduce  dependence  on  those  limited  sources  of  suppliers,  manufacturers  and 
service providers, the partial or complete loss of certain of these sources could have a material adverse effect on the Company’s operating results, financial 
condition and cash flows and damage its customer relationships. 

Deferred Financing Costs 

Deferred financing costs related to a recognized debt liability are recorded as a reduction of the carrying amount of the debt liability and amortized 

to interest expense using the effective interest method over the repayment term of the debt. 

Cash Equivalents 

The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. 

Restricted Cash 

As of December 31, 2023 and 2022, the Company maintained two letters of credit totaling $0.5 million for the benefit of the landlord of its leased 
property.  The  Company  was  required  to  maintain  a  separate  cash  balance  of  $0.5  million  to  secure  the  letters  of  credit.  Related  to  this  separate  cash 
balance, the Company classified $0.5 million as restricted cash (non-current) on its consolidated balance sheets as of December 31, 2023 and 2022.

Accounts Receivable 

Accounts receivable are presented net of an allowance for credit losses, which is an estimate of amounts that may not be collectible. The Company 
performs ongoing credit evaluations of its customers and monitors economic conditions to identify facts and circumstances that may indicate its receivables 
are at risk of collection. The Company provides reserves against accounts receivable for estimated credit losses, if any, that may result from a customer’s 
inability  to  pay  based  on  the  composition  of  its  accounts  receivable,  current  economic  conditions  and  historical  credit  loss  activity.  Amounts  deemed 
uncollectible are 

91

 
charged or written-off against the reserve. As of December 31, 2023 and 2022, the Company had no allowance for credit losses. During the years ended 
December 31, 2023, 2022 and 2021, the Company did not record any provisions for credit losses. During the year ended December 31, 2022, the Company 
wrote off less than $0.1 million of accounts receivable balances. During the years ended December 31, 2023 and 2021, the Company did not write off any 
accounts receivable balances. 

Business Combinations 

  In  determining  whether  an  acquisition  should  be  accounted  for  as  a  business  combination  or  asset  acquisition,  the  Company  first  determines 
whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If 
this is the case, the single identifiable asset or the group of similar assets is not deemed to be a business and the acquisition is accounted for as an asset 
acquisition. If this is not the case, the Company then further evaluates whether the acquisition includes, at a minimum, an input and a substantive process 
that together significantly contribute to the ability to create outputs. If so, the Company concludes that the acquisition is a business and accounts for it as a 
business combination. 

The Company accounts for business combinations using the acquisition method of accounting. In accordance with this method, assets acquired and 
liabilities  assumed  are  recorded  at  their  respective  fair  values  at  the  acquisition  date.  The  fair  value  of  the  consideration  paid  is  assigned  to  the  assets 
acquired and liabilities assumed based on their respective fair values. Goodwill represents the excess of the purchase price over the estimated fair values of 
the assets acquired and liabilities assumed.

Determining the fair value of assets acquired and liabilities assumed is judgmental in nature and can involve the use of significant estimates and 
assumptions.  Fair  value  and  useful  life  determinations  are  based  on,  among  other  things,  valuations  that  use  information  and  assumptions  provided  by 
management, which consider management’s best estimates of inputs and assumptions that a market participant would use. Actual results may vary from 
these estimates and may result in adjustments to goodwill and acquisition date fair values of assets and liabilities during a measurement period or upon a 
final determination of asset and liability fair values, whichever comes first. Adjustments to fair values of assets and liabilities made after the end of the 
measurement period are recorded within operating results. 

Transaction  costs  related  to  business  combinations  are  expensed  as  incurred  and  are  included  in  general  and  administrative  expense  in  the 

consolidated statements of operations. 

Asset Acquisitions 

The Company measures and recognizes asset acquisitions that are not deemed to be business combinations based on the cost to acquire the asset or 
group of assets, which includes transaction costs. Goodwill is not recognized in asset acquisitions. In an asset acquisition, the cost allocated to acquire in-
process research and development (“IPR&D”) with no alternative future use is charged to expense at the acquisition date.

On August 2, 2023, the Company acquired certain assets related to lung and heart perfusion technology from Bridge to Life Ltd. and its subsidiary 
Tevosol,  Inc.,  together  (“BTL”).  The  Company  intends  to  further  develop  these  technologies  to  expand  its  product  offerings  and  indications  for  organ 
transplantation. The Company accounted for the purchase of BTL as an asset acquisition as substantially all of the fair value of gross assets acquired were 
concentrated  on  a  single  set  of  identifiable  activities  consisting  of  lung  and  heart  perfusion  technology,  referred  to  as  the  in-process  research  and 
development (“IPR&D”) asset. Due to the stage of development of the IPR&D asset at the date of acquisition, it was not yet probable that there was future 
economic benefit from this asset. Absent successful clinical results and regulatory approval for the asset applications, there was no alternative future use 
associated  with  the  asset.  Accordingly,  the  value  of  the  IPR&D  asset  of  $27.2  million  was  expensed  as  research  and  development  expense  in  the 
consolidated statements of operations. 

Goodwill and Acquired Intangible Assets

The Company records goodwill when consideration paid in a business combination exceeds the value of the net assets acquired. The Company’s 
estimates of fair value are based upon assumptions believed to be reasonable at that time, but that are inherently uncertain and unpredictable. Goodwill is 
not amortized, but rather is tested for impairment annually in the fourth quarter, or more frequently if facts and circumstances warrant a review, such as 
significant  underperformance  of  the  business  in  relation  to  expectations,  significant  negative  industry  or  economic  trends  and  significant  changes  or 
planned changes in the use of the assets.

92

 
The Company has determined that there is a single reporting unit for the purpose of conducting this goodwill impairment assessment. The Company 
has  the  option  of  performing  either  a  qualitative  or  quantitative  assessment  to  determine  whether  further  impairment  testing  is  necessary.  If  it  is  more-
likely-than-not  that  the  fair  value  of  a  reporting  unit  is  less  than  its  carrying  amount,  a  quantitative  impairment  test  will  be  required.  The  quantitative 
goodwill impairment test requires management to estimate and compare the fair value of the reporting unit with its carrying value. If the fair value of the 
reporting unit exceeds the carrying value of the net assets, goodwill is not impaired. If the fair value of the reporting unit is less than the carrying value, the 
difference is recorded as an impairment loss up to the amount of goodwill.

Intangible  assets  are  recorded  at  their  estimated  fair  values  at  the  date  of  acquisition  and  are  reported  net  of  accumulated  amortization.  The 
Company  amortizes  acquired  intangible  assets  with  finite  lives  over  their  estimated  useful  lives  based  on  the  pattern  of  consumption  of  the  economic 
benefits or, if that pattern cannot be readily determined, on a straight-line basis. 

Property, Plant and Equipment 

Property,  plant  and  equipment  are  stated  at  cost  less  accumulated  depreciation  and  amortization.  Depreciation  and  amortization  expense  is 

recognized using the straight-line method over the estimated useful life of each asset as follows: 

Transplant aircraft
Flight school aircraft
Manufacturing equipment
OCS Consoles
Computer equipment and software
Laboratory equipment
Office, trade show and training equipment
Leasehold improvements

Estimated Useful Life
10 years
5 years
5 years
5 years
3 years
3 years
5 years
Shorter of term of lease or 15 years

Depreciation and amortization expense of aircraft is recognized over the estimated useful lives of each asset to their salvage value. Salvage values 

estimated for transplant and flight school aircraft are approximately 50% of the original purchase price. 

Costs incurred for OCS Consoles are recorded as inventory unless and until the Company determines that an OCS Console will either be used for 
the NOP or loaned to a customer for its use, at which time the Company reclassifies the cost of the OCS Console from inventory to property, plant and 
equipment  and  begins  to  depreciate  the  OCS  Console  over  its  estimated  useful  life.  Such  depreciation  expense  is  classified  as  a  cost  of  revenue.  The 
Company retains title to all OCS Consoles loaned to customers. 

Costs  for  capital  assets  not  yet  placed  into  service  are  capitalized  as  construction-in-progress  and  depreciated  once  placed  into  service.  Upon 
retirement  or  sale,  the  cost  of  assets  disposed  of  and  the  related  accumulated  depreciation  and  amortization  are  removed  from  the  accounts  and  any 
resulting gain or loss is included in loss from operations. Expenditures for repairs and maintenance are charged to expense as incurred. 

Impairment of Long-Lived Assets 

Long-lived assets consist primarily of property, plant and equipment, right-of-use assets and intangible assets with finite lives. Long-lived assets to 
be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not 
be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the 
business in relation to expectations, significant negative industry or economic trends and significant changes or planned changes in the use of the assets. If 
an impairment review is performed to evaluate a long-lived asset group for recoverability, the Company compares forecasts of undiscounted cash flows 
expected to result from the use and eventual disposition of the long-lived asset group to its carrying value. An impairment loss would be recognized in loss 
from operations when estimated undiscounted future cash flows expected to result from the use of an asset group are less than its carrying amount. The 
impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value, determined based on discounted cash 
flows. The Company did not record any impairment losses on long-lived assets during the years ended December 31, 2023, 2022 and 2021.

Software Development Costs 

The Company incurs costs to develop computer software that is embedded in the hardware components of the Company’s OCS Console and OCS 

Perfusion Sets. Research and development costs related to this software are expensed as incurred, except 

93

 
 
 
 
 
 
 
 
 
 
 
 
 
for costs of internally developed or externally purchased software that qualify for capitalization. Software development costs incurred subsequent to the 
establishment of technological feasibility, but prior to the general release of the product, are capitalized and amortized over their estimated useful life. Due 
to the short time period between achieving technological feasibility and product release and the insignificant amount of costs incurred during such periods, 
the Company did not capitalize any software development costs during the years ended December 31, 2023, 2022 and 2021. 

The Company also capitalizes development costs related to internal-use software when it is probable that the expenditures will result in additional 
functionality. Costs incurred in the preliminary and post-implementation stages of development are expensed as incurred. Once an application has reached 
the development stage, internal and external costs, if direct and incremental, are capitalized until the software is substantially complete and ready for its 
intended  use  and  depreciated  over  their  estimated  useful  life.  Capitalization  ceases  upon  completion  of  all  substantial  testing  performed  to  ensure  the 
product  is  ready  for  its  intended  use.  The  Company  did  not  capitalize  any  software  development  costs  related  to  internal-use  software  during  the  years 
ended December 31, 2023, 2022 and 2021.  

Inventory 

Inventory is valued at the lower of cost or net realizable value. Cost is computed using the first-in, first-out method. The Company regularly reviews 
inventory  quantities  on-hand  for  excess  and  obsolete  inventory  and,  when  circumstances  indicate,  records  charges  to  write  down  inventories  to  their 
estimated  net  realizable  value,  after  evaluating  historical  sales,  future  demand,  market  conditions  and  expected  product  life  cycles.  Such  charges  are 
classified as cost of revenue in the consolidated statements of operations. Any write-down of inventory to net realizable value creates a new cost basis. 

At the end of each reporting period, the Company assesses whether losses should be accrued on long-term manufacturing purchase commitments in 
accordance with ASC 330, Inventory, which requires that losses that are expected to arise from firm, noncancelable and unhedged commitments for the 
future  purchase  of  inventory,  measured  in  the  same  way  as  inventory  losses,  should  be  recognized  in  the  current  period  in  the  statements  of  operations 
unless they are deemed recoverable through firm sales contacts or when there are other circumstances that reasonably assure continuing sales without price 
decline.  As  of  the  end  of  each  reporting  period  presented  in  the  accompanying  consolidated  financial  statements,  the  Company  did  not  identify  any 
potential losses arising from remaining future purchase commitments as compared to estimated future customer sales through the remainder of the term of 
the manufacturing purchase commitment and, as a result, did not recognize any loss provision for future-period remaining purchase commitments for the 
year ended December 31, 2023. 

Leases

The Company accounts for leases under ASC Topic 842, Leases (“ASC 842”). In accordance with ASC 842, the Company accounts for a contract as 
a  lease  when  it  has  the  right  to  control  the  asset  for  a  period  of  time  while  obtaining  substantially  all  of  the  asset’s  economic  benefits.  The  Company
determines  if  an  arrangement  is  a  lease  or  contains  an  embedded  lease  at  inception.  For  arrangements  that  meet  the  definition  of  a  lease,  the  Company 
determines the initial classification and measurement of its right-of-use asset and lease liability at the lease commencement date and thereafter if modified. 
The lease term includes any renewal options that the Company is reasonably assured to exercise. The present value of lease payments is determined by 
using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the Company uses its estimated secured incremental borrowing 
rate for that lease term. The Company’s policy is to not record leases with an original term of twelve months or less on its consolidated balance sheets and 
recognizes those lease payments in the income statement on a straight-line basis over the lease term. 

In addition to rent, the leases may require the Company to pay additional costs, such as utilities, maintenance and other operating costs, which are 
generally referred to as non-lease components. The Company has elected to not separate lease and non-lease components. Only the fixed costs for lease 
components and their associated non-lease components are accounted for as a single lease component and recognized as part of a right-of-use asset and 
lease  liability.  Rent  expense  for  operating  leases  is  recognized  on  a  straight-line  basis  over  the  reasonably  assured  lease  term  based  on  the  total  lease 
payments and is included in operating expense in the consolidated statements of operations.

Revenue from leasing arrangements is not subject to the revenue standard for contracts with customers and remains separately accounted for under 
ASC 842. In accordance with ASC 842, lessors should classify and account for a lease with variable lease payments that do not depend on a reference 
index  or  a  rate  as  an  operating  lease  if  the  lease  would  have  been  classified  as  a  sales-type  lease  or  a  direct  financing  lease  and  the  lessor  would  have 
otherwise recognized a day-one loss. The Company’s OCS Console implied rental agreements qualify as sales-type leases with certain variable payments 
that meet specified criteria such that a day-one loss would be recognized under ASC 842. Therefore, in accordance with ASC 842, such 

94

 
leases  are  accounted  for  as  operating  leases  and  the  Company  does  not  derecognize  the  leased  asset  (the  OCS  Console)  at  the  time  of  the  sale  but 
depreciates the leased asset over the useful life of the asset.

Fair Value Measurements 

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined 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. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair 
value hierarchy, of which the first two are considered observable and the last is considered unobservable: 

•

•

•

Level 1—Quoted prices in active markets for identical assets or liabilities. 

Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted 
prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by 
observable market data. 

Level  3—Unobservable  inputs  that  are  supported  by  little  or  no  market  activity  and  that  are  significant  to  determining  the  fair  value  of  the 
assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. 

The carrying values of the Company’s accounts receivable, accounts payable and accrued expenses approximate their fair values due to the short-
term nature of these assets and liabilities. The carrying value of the Company’s long-term debt approximates its fair value (a level 2 measurement) at each 
balance sheet date due to its variable interest rate, which approximates a market interest rate. The Company's 1.50% Convertible Senior Notes due 2028 
(the "Notes") are carried at the face value less unamortized debt discount and issuance costs on the consolidated balance sheets, and the fair value of the 
convertible senior notes is presented at each reporting period for disclosure purposes only (see Note 8). 

Segment Information 

The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. The Company 
has developed and is commercializing a proprietary system to preserve and deliver human organs for transplant in a near-physiologic condition to address 
the limitations of cold storage organ preservation. Operating segments are defined as components of an enterprise for which separate financial information 
is  regularly  evaluated  by  the  Company’s  chief  operating  decision  maker,  or  decision-making  group,  in  deciding  how  to  allocate  resources  and  assess 
performance. The Company has determined that its chief operating decision maker is its Chief Executive Officer. The Company’s chief operating decision 
maker reviews the Company’s financial information on a consolidated basis for purposes of allocating resources and assessing financial performance. 

Product Warranties 

The Company provides a one-year warranty on its OCS Consoles and disposable sets and replaces or repairs any OCS Console or disposable set that 
does not function in accordance with the product specifications. OCS Consoles returned to the Company may be refurbished and redeployed. Estimated 
warranty  costs  are  recorded  at  the  time  of  shipment  of  the  OCS  Console  or  disposable  set.  Warranty  costs  are  estimated  based  on  the  current  expected 
product replacement or repair cost and expected replacement or repair rates based on historical experience. The Company evaluates its warranty accrual at 
the end of each reporting period and makes adjustments as necessary. As of December 31, 2023 and 2022, the warranty accrual was less than $0.1 million 
each. 

Revenue Recognition 

The Company generates net product revenue primarily from sales of its single-use, organ-specific disposable sets used on its organ-specific OCS 
Consoles.  To  a  lesser  extent,  the  Company  also  generates  product  revenue  from  the  sale  of  OCS  Consoles  to  customers  and  the  implied  rental  of  OCS 
Consoles  loaned  to  customers  at  no  charge.  For  each  new  transplant  procedure,  customers  purchase  an  additional  OCS  disposable  set  for  use  on  the 
customer’s  existing  organ-specific  OCS  Console.  The  Company  also  generates  service  revenue  by  providing  outsourced  organ  retrieval,  OCS  organ 
management and logistics services under its NOP in the United States.

95

 
The Company recognizes revenue from sales to customers applying the following five steps: (1) identification of the contract, or contracts, with a 
customer, (2) identification of the performance obligations in the contract, (3) determination of the transaction price, (4) allocation of the transaction price 
to the performance obligations in the contract, and (5) recognition of revenue when, or as, performance obligations are satisfied. 

Substantially all of the Company’s customer contracts have multiple-performance obligations that contain deliverables consisting of OCS Perfusion 
Sets and OCS Solutions. Customer contract deliverables may also include organ retrieval, OCS organ management services and organ transportation under 
the Company's NOP or an OCS Console, whether sold or loaned to the customer. The Company evaluates each promise within a multiple-performance 
obligation  arrangement  to  determine  whether  it  represents  a  distinct  performance  obligation.  The  primary  performance  obligations  in  the  Company’s 
customer arrangements from which it derives revenue are the OCS Perfusion Sets, the OCS Solutions, the OCS Console, organ retrieval services, OCS 
organ management services and organ transportation logistics. 

When  a  customer  order  includes  an  OCS  Console,  the  Company  has  determined  that  customer  training  and  the  equipment  set-up  of  the  OCS 
Console, each performed by the Company, are not distinct because they are not sold on a standalone basis and can only be performed by the Company in 
conjunction  with  a  sale  or  loan  of  its  OCS  Console.  In  addition,  the  Company  has  determined  that  the  OCS  Console  itself  is  not  distinct  because  the 
customer cannot benefit from the OCS Console without the training and equipment set-up having been completed. As a result, when the order includes an 
OCS  Console,  the  Company  has  concluded  that  training,  OCS  Console  equipment  set-up,  and  the  OCS  Console  itself  are  highly  interdependent  and 
represent a single, combined performance obligation. The Company recognizes revenue from the single, combined performance obligation only once the 
OCS Console has arrived at the customer site and the training and equipment set-up have been completed by the Company. 

Customer orders may include the loan of an OCS Console as well as OCS disposable sets used in each transplant procedure. When the Company 
loans the OCS Console to the customer, it retains title to the console at all times and does not require minimum purchase commitments from the customer 
related to any OCS products. In such cases, the Company invoices the customer for OCS disposable sets based on customer orders received for each new 
transplant procedure and the prices set forth in the customer agreement. Over time, the Company typically recovers the cost of the loaned OCS Console 
through the customer’s continued purchasing and use of additional OCS disposable sets. For these reasons, the Company has determined that part of the 
arrangement  consideration  for  the  disposable  set  is  an  implied  rental  payment  for  use  of  the  OCS  Console.  Therefore,  the  Company  allocates  the 
arrangement consideration between the lease deliverables (i.e., the OCS Console) and non-lease deliverables (i.e., the OCS disposable sets) based on the 
relative  estimated  standalone  selling  price  of  each  distinct  performance  obligation.  To  date,  the  amounts  allocated  to  lease  deliverables  have  been 
insignificant. 

Revenue from sales to customers of OCS Perfusion Sets, OCS Solutions and OCS Consoles is classified as net product revenue in the Company's 
consolidated  statements  of  operations.  Revenue  from  sales  to  customers  of  organ  retrieval,  OCS  organ  management  services  and  organ  transportation 
logistics is classified as service revenue in the Company’s consolidated statements of operations. 

Revenue is recognized when control is transferred to the customer in an amount that reflects the consideration the Company expects to be entitled to 
in exchange for the product or services. When a customer order includes disposable sets and organ retrieval, OCS organ management or logistics services, 
the Company has determined that the disposable sets and services constitute separate performance obligations and recognizes revenue as the disposable sets 
and services are each delivered to the customer. 

Payments Made to Customers 

Under some of the Company’s customer clinical trial agreements, the Company makes payments to its customers for reimbursements of clinical trial 
materials  and  for  specified  clinical  documentation  related  to  the  customer’s  use  of  its  OCS  products.  The  Company  also  makes  payments  to  customers 
involved  in  post-approval  studies  for  information  related  to  the  transplant  procedures  performed.  The  Company  determines  the  appropriate  accounting 
treatments for these payments depending on the nature of the payment and whether they are for distinct goods or services. 

96

 
Contract Assets and Liabilities 

The Company recognizes a receivable at the point in time at which it has an unconditional right to payment. Such receivables are not contract assets. 
Contract  assets  arise  from  unbilled  amounts  in  customer  arrangements  when  revenue  recognized  exceeds  the  amount  billed  to  the  customer  and  the 
Company’s right to payment is not just subject to the passage of time. The Company had no contract assets as of December 31, 2023 and 2022. 

Contract liabilities represent the Company’s obligation to transfer goods or services to a customer for which it has received consideration (or the 
amount is due) from the customer. The Company has determined that its only contract liabilities are deferred revenue, which consists of amounts that have 
been invoiced but that have not been recognized as revenue. 

Remaining Performance Obligations

The Company generally satisfies performance obligations within one year of the contract inception date, which amounts are included in deferred 

revenue and are not material.

Other Revenue Considerations

The Company only includes estimated variable amounts in the transaction price to the extent it is probable that a significant reversal of cumulative 
revenue  recognized  will  not  occur  when  the  uncertainty  associated  with  the  variable  consideration  is  resolved.  The  Company  does  not  assess  whether 
promised goods or services are performance obligations if they are deemed immaterial in the context of the contract with the customer. Additionally, the 
Company  does  not  assess  whether  a  contract  has  a  significant  financing  component  if  the  expectation  at  contract  inception  is  that  the  period  between 
payment by the customer and the transfer of the promised goods or services to the customer will be one year or less. Revenue is reported net of taxes.

Distributors 

The  Company  markets  and  sells  its  products  primarily  through  its  direct  sales  force,  which  sells  its  products  to  end  customers  globally.  A  small 
portion of the Company’s revenue is generated by sales to a limited number of distributors in Europe and Asia-Pacific. When the Company transacts with a 
distributor, its contractual arrangement is with the distributor and not with the end customer. Whether the Company transacts business with and receives the 
order from a distributor or directly from an end customer, its revenue recognition policy and resulting pattern of revenue recognition for the order are the 
same. 

Research, Development and Clinical Trials Costs 

Research,  development  and  clinical  trials  expenses  consist  of  costs  incurred  for  research  activities,  product  development,  hardware  and  software 
engineering and clinical trial activities, including salaries and bonuses, stock-based compensation, employee benefits, facilities costs, laboratory supplies, 
depreciation, testing, regulatory, data management and consulting costs. 

Research, development and clinical trials costs are expensed as incurred. Advance payments for goods or services to be received in the future for use 
in  research,  development  and  clinical  trials  activities  are  recorded  as  prepaid  expenses.  Such  prepaid  expenses  are  recognized  as  an  expense  when  the 
related goods have been delivered or the related services have been performed, or when it is no longer expected that the goods will be delivered or the 
services rendered. 

Patent Costs 

All patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred due to the uncertainty about 

the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses. 

Foreign Currency Translation 

The functional currency of each of the Company’s foreign subsidiaries is the currency of the local country. Assets and liabilities of the Company’s 
foreign  subsidiaries  are  translated  into  U.S.  dollars  using  the  period-end  exchange  rates,  and  income  and  expense  items  are  translated  into  U.S.  dollars 
using average exchange rates in effect during each period. The effects of these foreign currency translation adjustments are included in accumulated other 
comprehensive loss, a separate component of stockholders’ equity. 

97

 
The Company also incurs transaction gains and losses resulting from intercompany transactions as well as transactions with customers or vendors 
denominated  in  currencies  other  than  the  functional  currency  of  the  legal  entity  in  which  the  transaction  is  recorded.  Realized  and  unrealized  foreign 
currency transaction gains (losses) are included in the consolidated statements of operations as a component of other income (expense) and totaled $0.3 
million, ($1.3 million) and ($1.0 million) for the years ended December 31, 2023, 2022 and 2021, respectively. 

Stock-Based Compensation 

The Company accounts for stock-based awards granted to employees, non-employees and directors based on the fair value of the award on the date 
of grant. The fair value of option awards is measured using the Black-Scholes option-pricing model. The fair value of restricted common stock awards is 
measured based on the difference between market value of the Company’s common stock on date of grant and the purchase price (if any). Generally, the 
Company issues awards with only service-based vesting conditions. Compensation expense for those awards is recognized over the vesting period of the 
respective award using the straight-line method. The Company accounts for forfeitures as they occur and records compensation cost assuming all option 
holders  will  complete  the  requisite  service  period.  When  the  unvested  portion  of  an  award  is  forfeited,  the  Company  reverses  compensation  expense 
previously recognized in the period of the forfeiture.

The  Company  classifies  stock-based  compensation  expense  in  its  consolidated  statements  of  operations  in  the  same  manner  in  which  the  award 

recipient’s payroll costs are classified or in which the award recipient’s service payments are classified. 

Comprehensive Income (Loss) and Accumulated Other Comprehensive Income (Loss) 

Comprehensive income (loss) includes net income (loss) as well as other changes in stockholders’ equity that result from transactions and economic 
events  other  than  those  with  stockholders.  The  Company’s  only  elements  of  other  comprehensive  income  (loss)  are  foreign  currency  translation 
adjustments and unrealized gains (losses) on marketable securities. 

Accumulated other comprehensive income (loss) on the consolidated balance sheets consists primarily of foreign currency translation adjustments. 

Accumulated other comprehensive income (loss) attributable to unrealized gains (losses) on marketable securities has not been significant. 

Net Income (Loss) per Share 

Basic net income (loss) per common share is computed by dividing the net income (loss) by the weighted average number of shares of common 
stock outstanding for the period. Diluted net income (loss) per common share is computed by dividing net income (loss) by the weighted average number
of shares of common stock outstanding for the period, including potential dilutive common shares assuming the dilutive effect of outstanding stock awards, 
using the treasury stock method, and outstanding convertible notes, using the if-converted method. For periods in which the Company reports a net loss, 
diluted net loss per common share is the same as basic net loss per common share, since dilutive common shares are not assumed to have been issued if 
their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for each of the years ended December 31, 2023, 2022 and 
2021.

The Company’s potential dilutive securities have been excluded from the computation of diluted net loss per share as the effect would be to reduce 
the net loss per share. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from 
the computation of diluted net loss per share attributable to common stockholders for the periods indicated above because including them would have had 
an anti-dilutive effect:

Warrants to purchase common stock
Options to purchase common stock
Employee stock purchase plan
Restricted stock units
Restricted stock awards
Convertible senior notes

Income Taxes 

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for 
the expected future tax consequences of events that have been recognized in the financial statements or in the Company's tax returns. Deferred taxes are 
determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in 
which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company 
assesses the likelihood that its deferred tax assets will be realized and, to the extent it believes, based upon the weight of available evidence, that it is more 
likely  than  not  that  all  or  a  portion  of  the  deferred  tax  assets  will  not  be  realized,  a  valuation  allowance  is  established  through  a  charge  to  income  tax 
expense.  Potential  for  recovery  of  deferred  tax  assets  is  evaluated  by  analyzing  carryback  capacity  in  periods  with  taxable  income,  reversal  of  existing 
taxable temporary differences and estimating the future taxable profits expected and considering prudent and feasible tax planning strategies.

The  Company  accounts  for  uncertainty  in  income  taxes  recognized  in  the  financial  statements  by  applying  a  two-step  process  to  determine  the 
amount  of  tax  benefit  to  be  recognized.  First,  the  tax  position  must  be  evaluated  to  determine  the  likelihood  that  it  will  be  sustained  upon  external 
examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the 
amount of benefit to recognize in the financial statements. The amount of benefit that may be recognized is the largest amount that has a greater than 50% 
likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax 
benefits, that are considered appropriate as well as the related net interest and penalties.

Recently issued accounting pronouncements

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which 
requires public entities to disclose information about their reportable segments’ significant expenses and other segment items on an interim and annual 
basis. Public entities with a single reportable segment are required to apply the disclosure requirements in ASU 2023-07, as well as all existing segment 
disclosures and reconciliation requirements in ASC 280 on an interim and annual basis. ASU 2023-07 is effective for fiscal years beginning after December 
15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently 
assessing the impact of the adoption of this guidance.

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

entities, on an annual basis, to provide disclosure of specific categories in their tax rate reconciliations, as well as disclosure of income taxes paid 
disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company 
is currently assessing the impact of the adoption of this guidance.

Acquisition of Summit 

On August 16, 2023, the Company acquired Summit pursuant to the terms of an equity purchase agreement. Summit was a charter flight operator 
based in Bozeman, Montana. The acquisition enabled TransMedics to add aviation transportation services to its NOP and become a comprehensive national 
provider of donor organ retrieval and delivery in the United States. 

The  acquisition  was  accounted  for  as  a  purchase  of  a  business  under  ASC  Topic  805,  Business  Combinations.  Under  the  acquisition  method  of 
accounting,  the  assets  and  liabilities  were  recorded  as  of  the  acquisition  date,  at  their  respective  fair  values.  The  preliminary  purchase  consideration  of 
$14.9 million reflected an upfront cash payment of $18.0 million, net of cash acquired and working capital adjustments.

The Company’s consolidated financial statements reflect the preliminary allocation of the purchase price to the assets and liabilities assumed based 
on fair value as of the date of the acquisition. The Company's estimate of preliminary purchase consideration is subject to change upon finalizing working 
capital adjustments. The Company’s preliminary estimate of the fair value of specifically identifiable assets acquired and liabilities assumed as of the date 
of acquisition is subject to change upon finalizing its valuation analysis. During the three months ended December 31, 2023, the Company recorded an 
adjustment to goodwill of $0.3 million, representing an adjustment to its estimate of the fair value of accounts payable and deferred tax liabilities as of the 
acquisition date. The final determinations, which are expected to be completed by August 2024, may result in additional changes in the fair value of certain 
assets and liabilities as compared to these preliminary estimates.

Property, plant and equipment consist primarily of flight school aircraft and construction-in-progress related to a commercial aircraft hangar that 
Summit  is  in  the  process  of  constructing.  Flight  school  aircraft  were  valued  using  market  comparisons  adjusted  for  aircraft-specific  condition.  The  fair 
value of construction-in-progress approximated its cost.

Intangible assets consisted primarily of a customer relationship asset of $2.3 million related to flight school revenue and was valued using the multi-
period excess earnings method, a form of the income approach. Significant assumptions and estimates utilized in this model include the revenue growth 
rate, contract renewal probability and the discount rate. Intangible assets are being amortized on a straight-line basis to selling, general and administrative 
over their estimated useful lives of 12 years as of the acquisition date.

Goodwill  was  recognized  for  the  excess  purchase  price  over  the  fair  value  of  the  net  assets  acquired.  Goodwill  is  primarily  attributable  to  the 
workforce  of  the  acquired  business  (which  is  not  eligible  for  separate  recognition  as  an  identifiable  intangible  asset)  and  anticipated  synergies  between 
Summit’s existing business processes and the NOP. Goodwill from the acquisition is included within the Company’s one reporting unit and is included in
the Company’s enterprise-level annual review for impairment. Goodwill resulting from the acquisition is not deductible for tax purposes.

Deferred tax liabilities relate to the differences between the fair value recognized in purchase accounting and the tax basis of property, plant and 
equipment and intangible assets. The net deferred tax liability is a source of income to support the recognition of a portion of our existing deferred tax 
assets. Therefore, the Company recorded a tax benefit of $1.7 million for the release of a portion of its valuation allowance related to the net deferred tax 
liabilities recorded in purchase accounting. 

The Company incurred total transaction costs of $2.0 million for third-party professional services utilized for the acquisition, which are included in 
selling, general and administrative costs in the consolidated statements of operations. The operating results of the acquired entity have been included in the 
consolidated financial statements beginning on the acquisition date. Pro forma results of operations for the acquisition have not been presented as they are 
not material to the Company’s consolidated results of operations.

million,  respectively.  Construction-in-progress  as  of  December  31,  2023  primarily  relates  to  construction  of  a  commercial  aircraft  hangar  at  Bozeman 
Yellowstone International Airport in Bozeman, Montana. Substantially all of the Company's property, plant and equipment are held in the United States. 

6.      Goodwill and Intangible Assets

The carrying amount of goodwill was $12.0  million  as  of  December  31,  2023  related  to  the  Company’s  acquisition  of  Summit.  Goodwill  is  not 
amortized, but instead is reviewed for impairment at least annually or more frequently when events and circumstances occur indicating that the recorded 
goodwill may be impaired. To date, the Company has had no impairments to goodwill.

As of December 31, 2023, the estimated fair value of the Notes was $524.9 million. The fair value was determined based on the quoted price of the 

last trade of the Notes prior to the end of the reporting period in an inactive market, which is considered as Level 2 in the fair value hierarchy.

On  May  11,  2023,  the  Company  issued  $460.0  million  aggregate  principal  amount  of  the  Notes,  in  a  private  placement  to  qualified  institutional 
buyers pursuant to Rule 144A under the Securities Act, pursuant to an indenture dated May 11, 2023, by and between the Company and U.S. Bank Trust 
Company, National Association (the “Indenture”). 

The initial conversion price of the Notes is approximately $94.00 per share of common stock, which represents a premium of approximately 32.5% 
over the closing price of the Company’s common stock on May 8, 2023. The Notes will mature on June 1, 2028, unless earlier repurchased, redeemed or 
converted. The Company used $52.1 million of the proceeds from the sale of the Notes to fund the cost of entering into capped call transactions, described 
below. The proceeds from the issuance of the Notes were approximately $393.3 million, net of capped call transaction costs of $52.1 million and initial 
purchaser discounts and other debt issuance costs totaling $14.6 million.

The Notes bear interest at a rate of 1.50% per year and interest is payable semiannually in arrears on June 1 and December 1 of each year. The initial 
conversion rate is 10.6388 shares of common stock per $1,000 principal amount of the Notes, which represents an initial conversion price of approximately 
$94.00 per share of common stock. The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain events as 
described in the Indenture.

Before March  1,  2028,  noteholders  have  the  right  to  convert  their  Notes  only  upon  the  occurrence  of  certain  events,  including  certain  corporate 
events, and during the five business days immediately after any ten consecutive trading days in which the trading price per $1,000 principal amount of 
Notes is less than ninety eight percent (98%) of the as converted value. Additionally, the noteholder can convert their Notes during any calendar quarter 
(and only during such calendar quarter), commencing after the calendar quarter ending on September 30, 2023 but before March 1, 2028, provided the last 
reported sale price of the common stock for at least 20 trading days is greater than or equal to 130% of the conversion price during the 30 consecutive 
trading days ending on the last trading day of a calendar quarter. From and after March 1, 2028, noteholders may convert their Notes at any time at their 
election until the close of business on the second scheduled trading day immediately before the maturity date. The Company has the right to elect to settle 
conversions either in cash, shares or in a combination of cash and shares of its common stock.

Prior to June 8, 2026, the Notes will not be redeemable. On or after June 8, 2026, the Company may redeem for cash all or any portion of the Notes 
(subject to the partial redemption limitation set forth in the Indenture), at its option, if the last reported sale price of the Company’s common stock has been 
at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period 
(including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides 
notice of redemption. In addition, calling any Note for redemption will constitute a “Make-Whole Fundamental Change” (as defined in the Indenture) with 
respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted 
after it is called for redemption. 

The Company accounts for the Notes as a single liability in accordance with ASC 470-20 as the Company concluded that embedded conversion 
features within the Notes do not meet the requirements for bifurcation. Initial purchaser discounts and other debt issuance costs related to the Notes totaling 
$14.6 million were recorded by the Company as a debt discount. The debt discount is reflected as a reduction of the carrying value of the Notes on the 
Company’s consolidated balance sheets and is being accreted to interest expense over the term of the Notes using the effective interest method. During the 
year ended December 31, 2023, the Company recognized $6.2 million in interest expense related to the 1.50% cash coupon of the Notes and amortization
of the debt issuance costs. During the year ended December 31, 2023, the effective interest rate on the outstanding Notes was approximately 2.1%.

Capped Call Transactions

In  connection  with  the  offering  of  the  Notes,  the  Company  entered  into  privately  negotiated  capped  call  transactions  (the  “Capped  Calls”)  with 
certain financial institution counterparties (the “Option Counterparties”). The Capped Calls are generally intended to reduce or offset the potential dilution 
to  the  common  stock  upon  any  conversion  of  the  Notes  with  such  reduction  or  offset,  as  the  case  may  be,  subject  to  a  cap  based  on  the  cap  price.  For 
accounting purposes, the Capped Calls are separate transactions, and not part of the terms of the Notes. The Capped Calls are recorded in stockholders’ 
equity and are not accounted for as derivatives. The cost of $52.1 million incurred to purchase the Capped Calls were recorded as a reduction to common 
stock on the accompanying consolidated balance sheets. 

Each  of  the  Capped  Calls  has  an  initial  strike  price  of  approximately  $94.00  per  share,  subject  to  certain  adjustments,  which  corresponds  to  the 
initial conversion price of the Notes. The Capped Calls have an initial cap price of $141.88 per share, subject to certain adjustments. The Capped Calls 
cover, subject to anti-dilution adjustments, approximately 4,893,848 shares of the Company’s common stock, which is the same number of shares of the 
Company’s common stock initially underlying the Notes. The Capped Calls are subject to automatic exercise over a 40 trading day period commencing on 
April 3, 2028, subject to earlier termination under certain circumstances.

In  July  2022,  the  Company  entered  into  a  credit  agreement  with  Canadian  Imperial  Bank  of  Commerce  (“CIBC”),  as  amended  by  the  First 
Amendment to Credit Agreement, dated as of May 8, 2023, by and among the Company and CIBC (the “First Amendment”), the Second Amendment to 
Credit  Agreement,  dated  as  of  June  23,  2023,  by  and  among  the  Company,  and  CIBC  (the  “Second  Amendment”),  the  Third  Amendment  to  Credit 
Agreement, dated as of November 9, 2023, by and among the Company, and CIBC (the “Third Amendment”) (as amended, the “CIBC Credit Agreement”), 
pursuant to which the Company borrowed $60.0 million. In connection with the CIBC Credit Agreement, the Company repaid all amounts due under its 
previously outstanding credit agreement and recorded a loss on extinguishment of debt of $0.6 million during 2022, which amount was classified as other 
expense in the consolidated statements of operations. 

103

 
 
 
 
 
 
   
 
  
 
  
 
   
 
On May 8, 2023, the Company entered into the First Amendment, which among other items, allowed for the issuance of the Notes and capped call 
transactions. On June 23, 2023, the Company entered into the Second Amendment, which among other items, permits the Company to make acquisitions of 
equity or assets of another entity, subject to the conditions under the Second Amendment, including acquisitions, without further consent of CIBC, up to a 
maximum  amount  of  $50.0  million  for  the  cash  payable  in  connection  with  an  individual  acquisition  and  a  maximum  amount  in  aggregate  of  $150.0 
million for the total cash consideration payable for all acquisitions made by the Company on or after June 23, 2023. The definition of consolidated adjusted 
EBITDA  was  also  amended  by  the  Second  Amendment  to  add  a  provision  for  the  pro  forma  effect  of  any  acquisitions  that  occur  during  the  period. 
Additionally, pursuant to the Second Amendment, the parties agreed to extend the start of the principal repayment period to July 31, 2026, on which date 
the Company is obligated to begin repayment of the term loans in equal monthly installments until the maturity date in July 2027. On November 9, 2023, 
the  Company  entered  into  the  Third  Amendment,  which,  among  other  items,  permits  the  Company  to  make  acquisitions  of  equity  or  assets  of  another 
entity, subject to the conditions under the Third Amendment, without further consent of CIBC, for cash consideration in a maximum aggregate amount of 
$300.0 million for all such acquisitions made by the Company on or after November 9, 2023.

Borrowings  under  the  CIBC  Credit  Agreement  bear  interest  at  an  annual  rate  equal  to  either,  at  the  Company’s  option,  (i)  the  secured  overnight 
financing rate for an interest period selected by the Company, subject to a minimum of 1.50%, plus 2.0% or (ii) 1.0% plus the higher of a) the prime rate 
subject  to  a  minimum  of  4.0%  or  b)  the  Federal  Funds  Effective  Rate,  plus  0.5%.  At  the  Company’s  option,  the  Company  may  prepay  borrowings 
outstanding under the CIBC Credit Agreement, subject to a prepayment fee of 2.0% of outstanding borrowings if paid prior to 12 months after the closing 
date, and 1.0% if paid on or after 12 months after the closing date but prior to 24 months after the closing date.

In connection with entering into the CIBC Credit Agreement, the Company paid upfront fees and other costs of $1.5 million, which were recorded 
by the Company as a debt discount. The debt discount is reflected as a reduction of the carrying value of long-term debt on the Company’s consolidated 
balance sheets and is being accreted to interest expense over the term of the CIBC Credit Agreement using the effective interest method.

All  obligations  under  the  CIBC  Credit  Agreement  are  guaranteed  by  the  Company  and  each  of  its  material  subsidiaries.  All  obligations  of  the 
Company and each guarantor are secured by substantially all of the Company’s and each guarantor’s assets, including their intellectual property, subject to 
certain exceptions. Under the CIBC Credit Agreement, the Company has agreed to customary representations and warranties, events of default and certain 
affirmative  and  negative  covenants  to  which  it  will  remain  subject  until  maturity.  The  financial  covenants  include,  among  other  covenants,  (x)  a 
requirement to maintain a minimum liquidity amount of the greater of either (i) the consolidated adjusted EBITDA loss (or gain) for the trailing four month 
period (only if EBITDA is negative) and (ii) $10.0 million, and (y) a requirement to maintain total net revenue of at least 75% of the level set forth in the 
total revenue plan presented to CIBC. As discussed above, the definition of consolidated adjusted EBITDA was amended to include the pro forma effect of 
acquisitions. The obligations under the CIBC Credit Agreement are subject to acceleration upon the occurrence of specified events of default, including 
payment  default,  change  in  control,  bankruptcy,  insolvency,  certain  defaults  under  other  material  debt,  certain  events  with  respect  to  governmental 
approvals  (if  such  events  could  cause  a  material  adverse  change  in  the  Company’s  business),  failure  to  comply  with  certain  covenants  and  a  material 
adverse change in the Company’s business, operations or financial condition. As of December 31, 2023, the Company was in compliance with all financial 
covenants of the CIBC Credit Agreement.

During the continuance of an event of default, the interest rate per annum will be equal to the rate that would have otherwise been applicable at the 
time of the event of default plus 2.0%. If an event of default (other than certain events of bankruptcy or insolvency) occurs and is continuing, CIBC may 
declare  all  or  any  portion  of  the  outstanding  principal  amount  of  the  borrowings  plus  accrued  and  unpaid  interest  to  be  due  and  payable.  Upon  the 
occurrence of certain events of bankruptcy or insolvency, all of the outstanding principal amount of the borrowings plus accrued and unpaid interest will
automatically become due and payable. In addition, the Company may be required to prepay outstanding borrowings, subject to certain exceptions, with 
portions of net cash proceeds of certain asset sales and certain casualty and condemnation events.

The Company assessed all terms and features of the CIBC Credit Agreement in order to identify any potential embedded features that would require 
bifurcation. As part of this analysis, the Company assessed the economic characteristics and risks of the debt. The Company determined that all features of 
the CIBC Credit Agreement are either clearly and closely associated with a debt host or have a de minimis fair value and, as such, do not require separate 
accounting as a derivative liability.

As of December 31, 2023, the stated interest rate applicable to borrowings under the CIBC Credit Agreement was 7.3%. During the years ended 
December 31, 2023 and 2022, the weighted average effective interest rate on outstanding borrowings under the CIBC Credit Agreement was approximately 
7.7% and 6.6%, respectively.

Stock-Based Compensation 

2019 Stock Incentive Plan

The 2019 Stock Incentive Plan (the “2019 Plan”) provides for the grant of incentive stock options, nonqualified stock options, stock appreciation 
rights,  restricted  stock,  restricted  stock  units,  unrestricted  stock,  unrestricted  stock  units,  and  other  stock-based  awards  to  employees,  directors,  and 
consultants of the Company and its subsidiaries. The number of shares of common stock of TransMedics Group initially available for issuance under the 
2019 Plan was 3,428,571  shares,  plus  the  number  of  shares  underlying  awards  under  the  previously  outstanding  2014  Stock  Incentive  Plan  (the  “2014 
Plan”),  not  to  exceed  1,595,189  shares,  that  expire  or  are  terminated,  surrendered,  or  cancelled  without  the  delivery  of  shares,  are  forfeited  to  or 
repurchased by TransMedics Group or otherwise become available again for grant. Since the effectiveness of the Company’s 2019 Plan in April 2019, no 
awards have been made or will be made under the 2014 Plan. 

Shares withheld in payment of the exercise or purchase price of an award or in satisfaction of tax withholding requirements, and the shares covered 
by  a  stock  appreciation  right  for  which  any  portion  is  settled  in  stock,  will  reduce  the  number  of  shares  available  for  issuance  under  the  2019  Plan.  In 
addition, the number of shares available for issuance under the 2019 Plan (i) will not be increased by any shares delivered under the 2019 Plan that are 
subsequently repurchased using proceeds directly attributable to stock option exercises and (ii) will not be reduced by any awards that are settled in cash or 
that expire, become unexercisable, terminate or are forfeited to or repurchased by TransMedics Group without the issuance of stock under the 2019 Plan. 
On  May  25,  2023,  the  shareholders  of  the  Company  approved  the  Amended  and  Restated  TransMedics  Group,  Inc.  2019  Stock  Incentive  Plan  (the 
“Amended Plan”) to among other things, (i) increase the number of shares of the Company’s common stock available for issuance thereunder by 1,000,000 
shares, (ii) prohibit the payment of dividend or dividend equivalents on a current basis with respect to unvested awards, (iii) extend the expiration date of 
the Amended Plan until June 1, 2033 and (iv) increase the annual limits on non-employee director compensation. As of December 31, 2023, 1,359,742 
shares of common stock were available for issuance under the Amended Plan. 

2021 Inducement Plan 

In August 2021, the Company’s board of directors approved the TransMedics Group, Inc. Inducement Plan (the “Inducement Plan”). Pursuant to the 
terms of the Inducement Plan, the Company may grant nonqualified stock options, stock appreciation rights, restricted stock, unrestricted stock, restricted 
stock  unit  awards  and  performance  awards  to  individuals  who  were  not  previously  employees  or  directors  of  the  Company  or  individuals  returning  to 
employment after a bona fide period of non-employment with the Company. A total of 1,000,000 shares of the Company’s common stock were initially 
available  for  issuance  under  the  Inducement  Plan.  On  November  2,  2023,  the  Company's  board  of  directors  approved  an  increase  of  500,000  to  shares 
available under the Inducement Plan. As of December 31, 2023, 607,366 shares of common stock remained available for issuance under the Inducement 
Plan.

105

 
 
Awards granted under the 2019 Plan and Inducement Plan vest over periods determined by the board of directors and expire no longer than ten years 

from the date of the grant. The exercise price for stock options granted is not less than the fair value of common shares based on quoted market prices. 

2019 Employee Stock Purchase Plan 

Pursuant  to  the  Company’s  2019  Employee  Stock  Purchase  Plan  (the  “2019  ESPP”),  certain  employees  of  the  Company  are  eligible  to  purchase
common stock of the Company at a reduced price during offering periods. The 2019 ESPP permits participants to purchase common stock using funds 
contributed through payroll deductions, subject to the limitations set forth in the Internal Revenue Code, at a purchase price of 85% of the lower of the 
closing price of the Company’s common stock on the first trading day of the offering period or the closing price on the applicable purchase date, which is 
the  final  trading  day  of  the  applicable  offering  period.  A  total  of  371,142  shares  of  common  stock  of  TransMedics  Group  were  initially  reserved  for 
issuance under the 2019 ESPP. During the year ended December 31, 2023, 25,894 shares were issued under the 2019 ESPP and as of December 31, 2023, 
264,559 shares remained available for issuance.

Stock Option Valuation 

The fair value of stock option grants is estimated using the Black-Scholes option-pricing model. Because there had been no public market for the 
Company's  common  stock  prior  to  the  Company's  initial  public  offering,  there  is  limited  Company-specific  historical  and  implied  volatility  data. 
Accordingly, the Company bases its estimates of expected volatility on a combination of the Company's own historical volatility and historical volatility of 
a  group  of  publicly-traded  companies  with  similar  characteristics  to  itself.  For  options  with  service-based  vesting  conditions,  the  expected  term  of  the 
Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest 
rate  is  determined  by  reference  to  the  U.S.  Treasury  yield  curve  in  effect  at  the  time  of  grant  of  the  award  for  time  periods  approximately  equal  to  the 
expected term of the award. Expected dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any 
cash dividends in the foreseeable future. 

The following table presents, on a weighted average basis, the assumptions used in the Black-Scholes option-pricing model to determine the grant-

date fair value of stock options granted to employees and directors:

respectively.

The Company has not granted any stock-based awards with performance-based vesting conditions.

Restricted Common Stock

Shares of unvested restricted common stock may not be sold or transferred by the holder. If the holder’s service to the Company and its affiliates 
ceases for any reason, unvested shares of restricted common stock held by these individuals will immediately be forfeited for no consideration, as provided 
in the individual restricted stock agreements.

Income Taxes 

Tax Provision Components

During the years ended December 31, 2023, 2022 and 2021, the Company recorded no income tax benefits for the net operating losses incurred or 
for  the  research  and  development  tax  credits  generated  in  each  year  in  the  United  States,  due  to  the  uncertainty  regarding  the  realizability  of  these 
respective deferred tax assets. The Company generated income in the Netherlands for the years ended December 31, 2023, 2022 and 2021 and, accordingly, 
recorded a foreign income tax provision of less than $0.1 million, $0.1 million and less than $0.1 million for the years ended December 31, 2023, 2022 and 
2021, respectively. 

The Company recorded a tax benefit of $1.7 million for the release of a portion of its valuation allowance related to the net deferred tax liabilities 
recorded  in  purchase  accounting  during  the  year  ended  December  31,  2023.  As  part  of  the  allocation  of  the  purchase  price  of  Summit,  the  Company 
recorded  deferred  tax  liabilities  for  the  differences  between  the  fair  value  recognized  in  purchase  accounting  and  the  tax  basis  of  property,  plant  and 
equipment  and  intangible  assets.  The  net  deferred  tax  liability  is  a  source  of  income  to  support  the  recognition  of  a  portion  of  its  existing  deferred  tax
assets.  Therefore,  the  Company  released  the  same  amount  of  its  valuation  allowance.  The  Company  maintains  a  valuation  allowance  on  its  overall  net 
deferred tax asset as it deems it more likely than not that the net deferred tax asset will not be realized.

As of December 31, 2023, the Company had federal net operating loss carryforwards of $376.4  million,  which  may  be  available  to  offset  future 
taxable income, of which $207.4 million of the total net operating loss carryforwards expire at various dates beginning in 2024, while the remaining $169.0 
million do not expire but are limited in their usage to an annual deduction equal to 80% of annual taxable income. As of December 31, 2023, the Company 
had state net operating loss carryforwards of $328.8 million, which may be available to offset future taxable income and expire at various dates beginning 
in 2030. As of December 31, 2023, the Company also had U.S. federal and state research and development tax credit carryforwards of $10.7 million and 
$6.5 million, respectively, which may be available to offset future tax liabilities and begin to expire in 2024. As of December 31, 2023, the Company had 
no foreign net operating loss carryforwards. 

Utilization of the U.S. federal and state net operating loss carryforwards and research and development tax credit carryforwards may be subject to a 
substantial  annual  limitation  under  Sections  382  and  383  of  the  Internal  Revenue  Code  of  1986,  and  corresponding  provisions  of  state  law,  due  to 
ownership changes that have occurred previously or that could occur in the future. These ownership changes may limit the amount of carryforwards that 
can  be  utilized  annually  to  offset  future  taxable  income  or  tax  liabilities.  In  general,  an  ownership  change,  as  defined  by  Section  382,  results  from 
transactions increasing the ownership of certain stockholders or public groups in the stock of a corporation by more than 50% over a three-year period. The 
Company  has  not  conducted  a  study  to  assess  whether  a  change  of  control  has  occurred  or  whether  there  have  been  multiple  changes  of  control  since 
inception  due  to  the  significant  complexity  and  cost  associated  with  such  a  study.  If  the  Company  has  experienced  a  change  of  control,  as  defined  by 
Section 382, at any time since inception, utilization of the net operating loss carryforwards or research and development tax credit carryforwards would be 
subject to an annual limitation under Section 382, which is determined by first multiplying the value of the Company’s stock at the time of the ownership 
change  by  the  applicable  long-term  tax-exempt  rate,  and  then  could  be  subject  to  additional  adjustments,  as  required.  Any  limitation  may  result  in 
expiration of a portion of the net operating loss carryforwards or research and development tax credit carryforwards before utilization. Further, until a study 
is completed by the Company and any limitation is known, no amounts are being presented as an uncertain tax position.

As required by Accounting Standard Codification 740, management of the Company has evaluated the positive and negative evidence bearing upon 
the realizability of its deferred tax assets, which are comprised principally of net operating loss carryforwards. Management has determined that it is more 
likely than not that the Company will not recognize the benefits of federal and state deferred tax assets and, as a result, a valuation allowance has been 
recorded.

As of December 31, 2023 and 2022, the Company had no accrued interest or penalties related to uncertain tax positions and no amounts had been 
recognized in the Company’s consolidated statements of operations. The Company's policy is to record any interest or penalties related to income taxes as 
part of the income tax provision.

The  Company  generated  research  credits  for  the  tax  years  ending  after  December  31,  2001  but  has  not  conducted  a  study  to  document  qualified 
activities. This study may result in an adjustment to the Company's research and development carryforwards; however, until a study is completed and any 
adjustment is known, no amounts are being presented as an unrecognized tax benefit for the year ended December 31, 2023. A full valuation allowance has 
been provided against the Company's research and development credits and, if an adjustment is required, this adjustment would be offset by an adjustment 
to the deferred tax asset established for the research credit carryforward and the valuation allowance.

The Company files income tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the 
Company is subject to examination by federal and state jurisdictions, where applicable. There are currently no pending federal or state tax examinations. 
The Company has open tax years subject to examination from fiscal year 2020 to present. To the extent that the Company has carryforward attributes, the 
tax years in which the attribute was generated may still be adjusted upon examination by federal, state or local tax authorities if they either have been or 
will be used in the future.

Changes in the valuation allowance for deferred tax assets during the year ended December 31, 2023 related primarily to current year federal and 
state net operating losses generated, acquired IPR&D and capitalized research and development costs. Changes in the valuation allowance for deferred tax 
assets during the year ended December 31, 2022 related primarily to the capitalization of research and development costs required under Section 174 and 
current  year  federal  and  state  net  operating  losses  generated,  partially  offset  by  a  decrease  in  deferred  tax  assets  related  to  state  net  operating  loss 
carryforwards due to a change in the state effective tax rate. Changes in the valuation allowance for deferred tax assets during the year ended December 31, 
2021 related primarily to the increase in net operating loss carryforwards in 2021. The changes in the valuation allowance were as follows (in thousands): 

Valuation allowance as of beginning of year

Decreases recorded as benefit to income tax provision
Increases recorded to income tax provision

The Company leases its office, laboratory and manufacturing space under two noncancelable leases that expire in December 2027  and  include  a 
lease incentive, fixed payment escalations, and rent holidays. The leases include an option to renew for an additional five years. The option to extend the 
lease term was not included in the right-of-use asset and the lease liability as it was not reasonably certain of being exercised. The Company classified the 
leases as operating leases under ASC 842. Annual base rent increases at an average rate of 2.5% each year until the end of the term. The Company is also 
obligated to pay the landlord certain costs, taxes, and operating expenses, subject to certain exclusions. As these costs are generally variable in nature, they 
are not included in the measurement of the right-of-use asset and related lease liability. In June 2023, the Company amended one of its lease agreements to 
add space through the remainder of the lease term and under the existing terms of the lease. 

In connection with the acquisition of Summit, the Company acquired a 20-year operating lease with one 10-year renewal option, for space at the 
Bozeman  Yellowstone  International  Airport  in  Bozeman,  Montana  where  the  Company  is  constructing  a  commercial  aircraft  hangar  (see  Note  3).  The 
Company also leases office space for its NOP and hangar space for its aircraft at various locations in the United States under short-term leases.

The weighted-average remaining lease term as of December 31, 2023 and 2022 was 4.7 years and 5.0 years, respectively. The weighted-average 
discount  rate  as  of  December  31,  2023  and  2022  was  6.9%  and  6.7%,  respectively.  Because  the  interest  rate  implicit  in  the  leases  was  not  readily 
determinable, the Company’s estimated incremental borrowing rate was used to calculate the present value of the leases. In determining its incremental 
borrowing rate, the Company considered its credit quality and assessed interest rates available in the market for similar borrowings, adjusted for the impact 
of collateral over the term of the leases.

The  Company  has  a  defined-contribution  savings  plan  under  Section  401(k)  of  the  Internal  Revenue  Code.  This  plan  covers  substantially  all 
employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. As 
of December 31, 2022, the Company had not made any contributions to the plan. Effective January 1, 2023, the Company instituted an employer matching 
program  for  the  401(k)  Plan  pursuant  to  which  the  Company  will  match  100%  of  the  first  3%  of  each  participating  employee’s  eligible  compensation 
contributed to the plan and 50% of up to an additional 2% each participating employee’s eligible compensation contributed to the plan. For the year ended
December 31, 2023, the Company recorded expense of $1.4 million related to these matching contributions.

Indemnification Agreements 

In the ordinary course of business, the Company has agreed to defend and indemnify its customers against third-party claims asserting infringement 
of  certain  intellectual  property  rights,  which  may  include  patents,  copyrights,  trademarks,  or  trade  secrets.  The  Company’s  exposure  under  these 
indemnification provisions is generally limited to the total amount paid by the end-customer under the agreement. However, certain agreements include 
indemnification  provisions  that  could  potentially  expose  the  Company  to  losses  in  excess  of  the  amount  received  under  the  agreement.  In  the  ordinary 
course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners, and other parties with 
respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims 
made by third parties. In addition, the Company has entered into indemnification agreements with members of its board of directors that will require the 
Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or services as directors or officers.

The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is, in many 
cases, unlimited. To date, the Company has not incurred any material costs as a result of such indemnifications. The Company is not currently aware of any 
indemnification claims and had not accrued any liabilities related to such obligations in its consolidated financial statements as of December 31, 2023 and 
2022. 

Unconditional Purchase Commitment

In January 2021, the Company entered into an unconditional $9.5 million purchase commitment, in the ordinary course of business, for goods with 
specified annual minimum quantities to be purchased through December 2029. The contract is not cancellable without penalty. The remaining purchase 
commitment as of December 31, 2023 was $7.0 million.

Legal Proceedings 

The Company is not currently party to any material legal proceedings. At each reporting date, the Company evaluates whether or not a potential loss 
amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for 
contingencies. The Company expenses as incurred the costs related to such legal proceedings. 

14.     Revenue

The Company has determined that the payments made to the customer for reimbursement of clinical trial materials and customer’s costs incurred to 
execute specific clinical trial protocols related to the Company’s OCS products do not provide the Company with a distinct good or service transferred by 
the  customer,  and  therefore  such  payments  are  recorded  as  a  reduction  of  revenue  from  the  customer  in  the  Company’s  consolidated  statements  of 
operations.  The  Company  records  the  reduction  of  revenue  in  the  same  period  as  the  revenue  is  recognized  and  records  a  corresponding  accrual  for  its 
estimate of the payments. As clinical trials reach the closeout phase, the Company updates its accrual estimates with corresponding adjustments to revenue. 
The Company will continue to update its clinical trial accrual estimates as information related to clinical trial payments is received. 

The reconciliation of gross product revenue to net product revenue for these certain payments is shown below (in thousands):

The  Company  determined  that  payments  made  to  customers  to  obtain  information  related  to  post-approval  studies  or  existing  standard-of-care 
protocols  (i.e.,  unrelated  to  the  Company’s  OCS  products)  meet  the  criteria  to  be  classified  as  a  cost  because  the  Company  receives  a  distinct  good  or 
service  transferred  by  the  customer  separate  from  the  customer’s  purchase  of  the  Company’s  OCS  products  and  the  consideration  paid  to  the  customer 
represents the fair value of the distinct good or service received. As a result, such payments made to the customers are recorded as operating expenses. The 
Company recorded payments made to customers related to post-approval studies and for documentation related to existing standard-of-care protocols of 
$0.9 million, $1.0 million and $2.1 million for the years ended December 31, 2023, 2022 and 2021, respectively, as operating expenses. 

Summit makes payments to its aircraft management customers who had opted in to Summit's charter program. Summit pays the aircraft owner a fee 
for the use of the aircraft for charter flight services. The Company determined that fees incurred for the use of aircraft management customers' aircraft meet 
the criteria to be classified as a cost because the Company receives a distinct good or service transferred by the customer separate from the customer’s 
purchase of Summit's aircraft management services and the consideration to the customer represents the fair value of the distinct good or service received. 
As a result, such fees are recorded as cost of sales. The Company recorded expense for the use of customers' aircraft of $1.1 million for the year ended 
December  31,  2023.  As  part  of  the  Summit  integration,  Summit's  legacy  aircraft  management  customers  are  being  transitioned  to  third  parties  and 
following this transition, the Company will no longer make such payments to customers.

Item 9A. Controls and Procedures. 

Evaluation of Disclosure Controls and Procedures 

Our  management,  with  the  participation  of  our  President  and  Chief  Executive  Officer  and  our  Chief  Financial  Officer  (our  principal  executive 
officer and principal financial and accounting officer, respectively), evaluated the effectiveness of our disclosure controls and procedures as of December 
31, 2023. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other 
procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the 
Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and 
procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports 
that  it  files  or  submits  under  the  Exchange  Act  is  accumulated  and  communicated  to  the  company’s  management,  including  its  principal  executive  and 
principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. 

Management  recognizes  that  any  controls  and  procedures,  no  matter  how  well  designed  and  operated,  can  provide  only  reasonable  assurance  of 
achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. 
Based  on  the  evaluation  of  our  disclosure  controls  and  procedures  as  of  December  31,  2023,  our  President  and  Chief  Executive  Officer  and  our  Chief 
Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Internal Control Over Financial Reporting

Management’s Annual Report on Internal Control over Financial Reporting 

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-
15(f)  and  15d-15(f)  promulgated  under  the  Exchange  Act as  a  process  designed  by,  or  under  the  supervision  of,  our  principal  executive  and  principal 
financial  officers  and  effected  by  our  board  of  directors,  management  and  other  personnel  to  provide  reasonable  assurance  regarding  the  reliability  of 
financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.

Internal control over financial reporting includes policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, 
accurately and fairly reflect transactions and disposition of assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with GAAP, and that receipts and expenditures are being made only in accordance with the authorization 
of its management and directors; and (3) provide reasonable assurance regarding the prevention or timely detection of unauthorized acquisition, use, or 
disposition of our assets that could have a material effect on its financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Also,  projections  of  any 
evaluation of the 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 and procedures included in such controls may deteriorate.

Our management conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2023 based on the 
criteria described in “Internal Control-Integrated Framework” (2013) issued by the Committee of Sponsoring Organization of the Treadway Commission. 
Based on this assessment, management concluded that, as of December 31, 2023, our internal control over financial reporting was effective.

We  have  excluded  Summit  Aviation,  Inc.  and  its  affiliated  entity,  Northside  Property  Group,  LLC,  or  together  Summit  (“Summit”)  from  our 
assessment  of  the  effectiveness  of  internal  control  over  financial  reporting  as  of  December  31,  2023,  because  it  was  acquired  in  a  purchase  business 
combination  during  2023.  The  total  assets  and  total  revenue  of  Summit,  which  is  a  wholly-owned  subsidiary,  that  are  excluded  from  our  assessment  of 
internal  control  over  financial  reporting  collectively  represent  approximately  2%  and  2%,  respectively,  of  the  related  consolidated  financial  statement 
amounts as of and for the year ended December 31, 2023.

114

 
The effectiveness of our internal control over financial reporting as of December 31, 2023 has been audited by PricewaterhouseCoopers, LLP, an 

independent registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control over Financial Reporting 

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the 
three months ended December 31, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 

Item 9B. Other Information. 

During our fiscal quarter ended December 31, 2023, one of our directors entered into a contract, instruction or written plan for the purchase or sale 
of our securities that is intended to satisfy the conditions specified in Rule 10b5-1(c) under the Exchange Act for an affirmative defense against liability for 
trading in securities on the basis of material nonpublic information. We refer to these contracts, instructions, and written plans as “Rule 10b5-1 trading 
plans” and each one as a “Rule 10b5-1 trading plan.”

Exhibit 97.1

TRANSMEDICS GROUP, INC.
POLICY FOR RECOUPMENT OF INCENTIVE COMPENSATION

1.

Introduction

In accordance with Section 10D of the Securities Exchange Act of 1934, as amended, and the regulations thereunder, the
Board  of  Directors  (the  “Board”)  of  TransMedics  Group,  Inc.  (the  “Company”)  has  adopted  this  policy  (the  “Policy”) 
providing for the Company’s recoupment of certain incentive-based compensation received by Covered Executives (as defined 
below) in the event that the Company is required to prepare an accounting restatement due to its material noncompliance with 
any financial reporting requirement under the securities laws.

2. Administration

Administration and enforcement of this Policy is delegated to the Compensation Committee of the Board (as constituted 
from time to time, and including any successor committee, the “Committee”). The Committee shall make all determinations 
under this Policy in its sole discretion. Determinations of the Committee under this Policy need not be uniform with respect to 
any or all Covered Executives and will be final and binding.

3. Effective Date

This  Policy  shall  be  effective  as  of  November  2,  2023  (the  “Effective  Date”)  and  shall  apply  only  to  Covered 
Compensation  (as  defined  below)  that  is  received  by  Covered  Executives  on  or  after  October  2,  2023,  except  as  otherwise 
agreed to by any Covered Executive.

4. Covered Executives

This Policy covers each current or former officer of the Company subject to Section 16 of the Securities Exchange Act of 

1934, as amended (each, a “Covered Executive”).

5. Covered Compensation

This Policy applies to any cash-based or equity-based incentive compensation, bonus, and/or award that is or was received 
by a Covered Executive and that is or was based, wholly or in part, upon the attainment of any financial reporting measure 
(“Covered Compensation”). This Policy shall apply to any Covered Compensation received by an employee who served as a 
Covered Executive at any time during the performance period for that Covered Compensation.

6. Financial Restatements; Recoupment

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

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
uncorrected in the current period (such an accounting restatement, a “Restatement”), the Committee shall review the Covered 
Compensation  received  by  a  Covered  Executive  during  the  three-year  period  preceding  the  Required  Financial  Restatement 
Date  (as  defined  below)  as  well  as  any  transition  period  that  results  from  a  change  in  the  Company’s  fiscal  year  within  or 
immediately  following  those  three  completed  fiscal  years.  Regardless  of  whether  the  Company  files  the  restated  financial 
statements,  the  Committee  shall,  to  the  fullest  extent  permitted  by  governing  law,  seek  recoupment  of  any  Covered 
Compensation, whether in the form of cash or equity, received by a Covered Executive (computed without regard to any taxes 
paid), if and to the extent:

a.

b.

the amount of the Covered Compensation was calculated based upon the achievement of certain financial results 
that were subsequently the subject of such Restatement; and

the  amount  of  the  Covered  Compensation  that  would  have  been  received  by  the  Covered  Executive  had  the 
financial  results  been  properly  reported  would  have  been  lower  than  the  amount  actually  awarded  (any  such 
amount, “Erroneously-Awarded Compensation”).

To the extent Covered Compensation was based on the achievement of a financial reporting measure, but the amount of 
such Covered Compensation was not awarded or paid on a formulaic basis, the Committee shall determine the amount, if any, 
of such Covered Compensation that will be deemed to be Erroneously-Awarded Compensation for purposes of this Policy.

For purposes of this Policy, the “Required Financial Restatement Date” is the earlier to occur

of:

a.

the date the Board, a committee of the Board, or any officer or officers authorized to take such action if Board 
action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare a 
Restatement; or

b.

the date a court, regulator, or other legally authorized body directs the Company to prepare a Restatement.

For  the  avoidance  of  doubt,  a  Covered  Executive  will  be  deemed  to  have  received  Covered  Compensation  in  the 
Company’s fiscal period during which the financial reporting measure specified in the award is attained, even if the Covered 
Executive remains subject to additional payment conditions with respect to such award.

7. Method of Recoupment

The Committee will determine, in its sole discretion, the method for recouping Erroneously- Awarded Compensation, which 

may include, without limitation:

a.
b.

requiring reimbursement of cash incentive compensation previously paid;
cancelling or rescinding some or all outstanding vested or unvested equity (and/or equity-based) awards;

 
 
 
 
 
 
 
 
 
 
 
 
c.

d.

adjusting or withholding from unpaid compensation or other set-off to the extent permitted by applicable law; 
and/or

reducing or eliminating future salary increases, cash-based or equity-based incentive compensation, bonuses, 
awards or severance.

8.

Impracticability Exceptions

The Committee shall not seek recoupment of any Erroneously-Awarded Compensation to the extent it determines that:

a.

the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount of Erroneously-
Awarded Compensation to be recovered;

b.

recovery would violate home country law where that law was adopted prior to November 28, 2022; and/or

c.

recovery  would  likely  cause  an  otherwise  tax-qualified  retirement  plan,  under  which  benefits  are  broadly 
available  to  Company  employees,  to  fail  to  meet  the  requirements  of  Sections  401(a)(13)  and  411(a)  of  the 
Internal Revenue Code of 1986, as amended, and the regulations thereunder.

9. No Indemnification

For the avoidance of doubt, the Company shall not indemnify any Covered Executive against the loss of any Erroneously-
Awarded  Compensation  or  any  Covered  Compensation  that  is  recouped  pursuant  to  the  terms  of  this  Policy,  or  any  claims 
relating to the Company’s enforcement of its rights under this Policy.

10. Acknowledgement by Covered Executives

The  Committee  shall  cause  the  Company  to  provide  notice  and  seek  written  acknowledgement  (in  the  form  attached 
hereto) of this Policy from each Covered Executive as soon as practicable after the later of (i) the Effective Date and (ii) the 
date  on  which  the  employee  is  designated  as  a  Covered  Executive;  provided,  however,  that  failure  to  obtain  such 
acknowledgement shall have no impact on the enforceability of this Policy.

11. Severability

If any provision of this Policy or the application of any such provision to any Covered Executive shall be adjudicated to be 
invalid,  illegal  or  unenforceable  in  any  respect,  such  invalidity,  illegality  or  unenforceability  shall  not  affect  any  other 
provisions of this Policy, and the

 
 
 
 
 
 
 
 
 
 
 
invalid, illegal or unenforceable provisions shall be deemed amended to the minimum extent necessary to render any such 
provision or application enforceable.

12. Amendments

The Committee may amend, modify or terminate this Policy in whole or in part at any time and may adopt such rules and 

procedures that it deems necessary or appropriate to implement this Policy or to comply with applicable laws and regulations.

13. No Impairment of Other Remedies

The  remedies  under  this  Policy  are  in  addition  to,  and  not  in  lieu  of,  any  legal  and  equitable  claims  the  Company  may 
have,  the  Company’s  ability  to  enforce,  without  duplication,  the  recoupment  provisions  set  forth  in  any  separate  Company 
policy or in any Company plan, program or agreement (each, a “Separate Recoupment Policy” and collectively, the “Separate 
Recoupment  Policies”),  or  any  actions  that  may  be  imposed  by  law  enforcement  agencies,  regulators  or  other  authorities. 
Notwithstanding  the  foregoing,  in  the  event  that  there  is  a  conflict  between  the  application  of  this  Policy  to  a  Covered 
Executive in the event of a Restatement and any additional recoupment provisions set forth in a Separate Recoupment Policy 
to which a Covered Executive is subject, the provisions of this Policy shall control. The Company may also adopt additional 
Separate Recoupment Policies in the future or amend existing requirements as required by law or regulation.
