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

The following discussion and analysis of the results of operations and financial condition for the fiscal years ended December 31, 2020, 2019 and 2018 should be read in conjunction with our financial statements, and the notes to those financial statements that are included elsewhere in this Report.

Overview

We are a leader in critical care immunotherapy using blood purification technology to treat deadly inflammation in hospitalized patients around the world. The technology is based upon biocompatible, highly porous polymer sorbent beads that are capable of extracting unwanted substances from blood and other bodily fluids. The technology is protected by 16 issued U.S. patents, multiple issued foreign patents and multiple applications pending both in the U.S. and internationally. Our intellectual property consists of composition of matter, materials, methods of production, systems incorporating the technology and multiple medical uses with expiration dates ranging from one to 15 years.

In March 2011, we received EU regulatory approval under the CE Mark and Medical Devices Directive for our flagship product, CytoSorb, as an extracorporeal cytokine filter indicated for use in clinical situations where cytokines are elevated. The goal of CytoSorb is to prevent or treat organ failure by reducing cytokine storm and the potentially deadly systemic inflammatory response syndrome in diseases such as sepsis, trauma, burn injury, acute respiratory distress syndrome, pancreatitis, liver failure, and many others. Organ failure is the leading cause of death in the ICU, and remains a major unmet medical need, with little more than supportive care therapy (e.g., mechanical ventilation, dialysis, vasopressors, fluid support, ECMO, etc.) as treatment options. By potentially preventing or treating organ failure, CytoSorb may improve clinical outcome, including survival, while reducing the need for costly ICU treatment, thereby potentially saving significant healthcare costs. CytoSorb is also being used during and after cardiac surgery to remove inflammatory mediators, such as cytokines and free hemoglobin, which can lead to post-operative complications including multiple organ failure. In January 2018, the Company received approval for the first CytoSorb label expansion increasing treatment time from six hours to 24 hours. In May 2018, we received a label expansion for CytoSorb covering use of the device for the removal of bilirubin and myoglobin in the treatment of liver disease and trauma, respectively. In January 2020, we received CE-Mark label expansion for CytoSorb covering the use of the device for the removal of the anti-platelet agent, ticagrelor, in patients undergoing surgery requiring cardiopulmonary bypass. In April 2020, the United States Food and Drug Administration (the “FDA”) granted Breakthrough Designation to CytoSorb for the removal of ticagrelor in a cardiopulmonary bypass circuit during emergent and urgent cardiothoracic surgery. In April 2020, we announced that the FDA has granted Emergency Use Authorization (“EUA”) of CytoSorb for use in patients with COVID-19 infection. In May 2020, we received CE-Mark label expansion for CytoSorb for the removal of rivaroxaban during cardiothoracic surgery requiring cardiopulmonary bypass.

Our CE Mark enables CytoSorb to be sold throughout all 27 countries of the EU and the United Kingdom. In addition, many countries outside the EU accept CE Mark approval for medical devices, but may also require registration with or without additional clinical studies. The broad approved indication enables CytoSorb to be used “on-label” in diseases where cytokines are elevated including, but not limited to, critical illnesses such as those mentioned above, autoimmune disease flares, cancer cachexia, and many other conditions where cytokine-induced inflammation plays a detrimental role.

As part of the CE Mark approval process, we completed our randomized, controlled, European Sepsis Trial amongst fourteen trial sites in Germany in 2011, with enrollment of 100 patients with predominantly septic shock and respiratory failure. The trial established that CytoSorb was safe in this critically-ill population, and that it was able to broadly reduce key cytokines from the blood of these patients. We plan to conduct larger, prospective studies in septic patients in the future to confirm the European Sepsis Trial findings.

In addition to CE Mark approval, we also achieved ISO 13485:20016 Full Quality Systems certification, an internationally recognized quality standard designed to ensure that medical device manufacturers have the necessary comprehensive management systems in place to safely design, develop, manufacture and distribute medical devices in the EU. We manufacture CytoSorb at our manufacturing facilities in New Jersey for sale and for additional clinical studies. We also established specific reimbursement for CytoSorb in Germany. We have also been assigned two specific procedure codes for our CytoSorb device in Switzerland that are pending reimbursement valuation assignment.

From September 2011 through June 2012, we began a controlled market release of CytoSorb in select geographic territories in Germany with the primary goal of preparing for commercialization of CytoSorb in Germany in terms of manufacturing, reimbursement, logistics, infrastructure, marketing, contacts, and other key issues.

In late June 2012, following the establishment of our European subsidiary, CytoSorbents Europe GmbH, we began the commercial launch of CytoSorb in Germany with the hiring of Dr. Christian Steiner as Vice President of Sales and Marketing and three additional sales representatives. The fourth quarter of 2012 represented the first full quarter of direct sales with the full sales team in place. During this period, we expanded our direct sales efforts to include both Austria and Switzerland.

In March 2016, we established CytoSorbents Switzerland GmbH, a wholly-owned subsidiary of CytoSorbents Europe GmbH, to conduct marketing and direct sales in Switzerland. This subsidiary began operations during the second quarter of 2016. In 2017, we further expanded our direct sales efforts into Belgium and Luxemburg.

On March 5, 2019, the Company announced the expansion of direct sales of CytoSorb for all applications to Poland and the Netherlands, and critical care applications to Sweden, Denmark and Norway. As part of this effort, the Company established CytoSorbents Poland Sp. Z.o.o., a wholly-owned subsidiary of CytoSorbents Europe GmbH.

In the third quarter of 2019, we established CytoSorbents UK Limited, a wholly-owned subsidiary of CytoSorbents Medical, Inc., to manage our clinical trial activities in the United Kingdom.

In January 2020, we received CE-Mark label expansion approving the use of CytoSorb to remove the anti-platelet agent, ticagrelor, in cardiac patients during surgery requiring cardiopulmonary bypass.

In April 2020, the Company announced that the United States Food and Drug Administration (the “FDA”) granted Emergency Use Authorization (“EUA”) of CytoSorb for use in critically-ill patients infected with COVID-19. Under the EUA, the Company can make CytoSorb available, through commercial sales, to all hospitals in the United States for use in patients, 18 years of age or older, with confirmed COVID-19 infection who are admitted to the intensive care unit (ICU) with confirmed or imminent respiratory failure who have early acute lung injury or acute respiratory distress syndrome (ARDS), severe disease, or life-threatening illness resulting in respiratory failure, septic shock, and/or multiple organ dysfunction or failure. The CytoSorb device has neither been cleared nor approved for the indication to treat patients with COVID-19 infection. The EUA will be effective until a declaration is made that the circumstances justifying the EUA have terminated or until revoked by the FDA.

In April 2020, the Company also announced that the FDA had granted Breakthrough Designation to CytoSorb for the removal of ticagrelor in a cardiopulmonary bypass circuit during emergent and urgent cardiothoracic surgery. The Breakthrough Devices Program provides for more effective treatment of life-threatening or irreversibly debilitating disease or conditions, in this case the need to reverse the effects of ticagrelor in emergent or urgent cardiac surgery that can otherwise cause a high risk of serious or life-threatening bleeding. Through Breakthrough Designation, the FDA intends to work with CytoSorbents to expedite the development, assessment, and regulatory review of CytoSorb for the removal of ticagrelor, while maintaining statutory standards of regulatory approval (e.g., 510(k), de novo 510(k) or premarket approval) consistent with the FDA’s mission to protect and promote public health.

In May 2020, we received CE-Mark label expansion approving the use of CytoSorb for the removal of rivaroxaban, a widely-used Factor Xa inhibitor and novel oral anticoagulant, during cardiothoracic surgery requiring cardiopulmonary bypass. With this announcement, and the E.U. approval earlier this year to remove ticagrelor, for the same indication, CytoSorb is providing cardiac surgeons and perfusionists an easy-to-use and rapid new treatment option to help reduce the risk of serious and potentially fatal perioperative bleeding complications caused by these two drugs, in separate categories of blood thinners.

At the end of 2020, we had hundreds of KOLs in our commercialized territories worldwide in critical care, cardiac surgery, and blood purification who were either using CytoSorb or supporting its use in clinical practice or clinical trials.

As of March 1, 2021, our European commercialization team includes 95 people.

Overall, we have established either direct sales or distribution (via distributors or strategic partners) of CytoSorb in 67 countries worldwide. Registration of CytoSorb is typically required in each of these countries prior to active commercialization. With CE Mark approval, this can be typically achieved within several months in EU countries. Outside of the EU, the process is more variable and can take several months to more than a year due to different requirements for documentation and clinical data. Variability in the timing of registration affects the initiation of active commercialization in these countries, which affects the timing of expected CytoSorb sales. We actively support all of our distributors and strategic partners in the product registration process. We cannot generally predict the timing of these registrations, and there can be no guarantee that we will ultimately achieve registration in countries where we have established distribution. For example, in August 2014 we announced exclusive distribution of CytoSorb in Taiwan with Hemoscien Corporation. However, in March 2015, due to the complexity we encountered with Taiwanese product registration, we elected to terminate our agreement with Hemoscien. Outside of the EU, CytoSorb has distribution in Turkey, India, Sri Lanka, Australia, New

Zealand, Russia, Serbia, Norway, Vietnam, Malaysia, Hong Kong, Chile, Panama, Costa Rica, Colombia, Brazil, Mexico, Argentina, Perú, Guatemala, Ecuador, Bolivia, the Dominican Republic, El Salvador, Iceland, Israel, UAE, Iran, Saudi Arabia and other Middle Eastern countries, and South Korea. We cannot guarantee that we will generate meaningful sales in the countries where we have established registration, due to other factors such as market adoption and reimbursement. For example, in December 2019, we discontinued our distributor relationship with Dr. Reddy’s in South Africa due to lack of market adoption. We continuously evaluate other potential distributor and strategic partner networks in other countries that accept CE Mark approval.

We have been working to expand the number and scope of our strategic partnerships. In September 2013, we entered into a strategic partnership with Biocon Biologics Limited, India’s largest biopharmaceuticals company, with an initial distribution agreement for India and select emerging markets, under which Biocon has the exclusive commercialization rights for CytoSorb initially focused on sepsis. In October 2014, the Biocon partnership was expanded to include all critical care applications and cardiac surgery. In addition, Biocon committed to higher annual minimum purchases of CytoSorb to maintain distribution exclusivity and committed to conduct and publish results from multiple investigator-initiated studies and patient case studies. In December 2017, the Biocon partnership was further expanded to include exclusive distribution of CytoSorb in Malaysia. Under the terms of the agreement, Biocon has committed to minimum annual purchases in Malaysia to maintain exclusivity this territory. In addition, the term of the original agreement was extended to December 2022.

In December 2014, we entered into a multi-country strategic partnership with Fresenius Medical Care AG & Co KGaA (“Fresenius”) to commercialize the CytoSorb therapy. Under the agreement reflecting the terms of the partnership, Fresenius was granted exclusive rights to distribute CytoSorb for critical care applications in France, Poland, Sweden, Denmark, Norway, and Finland. The partnership allows Fresenius to offer an innovative and easy way to use blood purification therapy for removing cytokines in patients that are treated in the ICU. To promote the success of CytoSorb, Fresenius agreed to also engage in the ongoing clinical development of the product. This includes the support and publication of a number of small case series and patient case reports as well as the potential for future larger, clinical collaborations. In May 2016, Fresenius launched the product in the six countries for which it was granted exclusive distribution rights. In January 2017, the Fresenius partnership was expanded pursuant to a revised three year agreement. The terms of the revised three-year agreement extended Fresenius’ exclusive distributorship of CytoSorb for all critical care applications in their existing territories through 2019 and include guaranteed minimum quarterly orders and payments, evaluable every one and a half years. At the same time, we entered into a new comprehensive co-marketing agreement with Fresenius. Under the terms of the co-marketing agreement, CytoSorbents and Fresenius agreed to jointly market CytoSorb to Fresenius’ critical care customer base in all countries where CytoSorb is being actively commercialized. CytoSorb will continue to be sold by our direct sales force or through our international network of distributors and partners, while Fresenius sells all ancillary products to their customers. Fresenius further agreed to provide written endorsements of CytoSorb for use with their multiFiltrate and multiFiltratePRO acute care dialysis machines that can be used by us and our distribution partners to promote CytoSorb worldwide. Training and preparation for this co-marketing program began in five initial countries in 2017 and is continuing, with implementation of the co-marketing program in additional countries planned for the future.

In December 2018, the Fresenius agreement originally signed in 2014 was amended, thereby modifying the territory to include exclusive distribution rights for Czech Republic and Finland and all critical care medicine and intensive care unit (ICU) applications on dialysis or ECMO machines for France. In addition, starting in 2019, Poland, Sweden, Denmark, and Norway were transitioned into the co-marketing program. Finally, the guaranteed minimum quarterly purchases and payments requirements were removed for 2019.

In addition, in this December 2018 reconfiguration of territories, the Fresenius partnership was expanded to include South Korea and Mexico. Under the terms of these agreements, Fresenius Medical Care has the exclusive rights to distribute CytoSorb for acute care and other hospital applications in South Korea and Mexico. Commercial sales of CytoSorb are underway in both countries after securing market registration clearance from Korean and Mexican health authorities in 2020. These multi-year agreements include an initial stocking order and are subject to annual minimum purchases of CytoSorb to maintain exclusivity.

In September 2016, we entered into a multi-country strategic partnership with Terumo Cardiovascular Group to commercialize CytoSorb for cardiac surgery applications. Under the terms of the agreement, Terumo has exclusive rights to distribute the CytoSorb cardiopulmonary bypass (“CPB”) procedure pack for intra-operative use during cardiac surgery in France, Sweden, Denmark, Norway, Finland and Iceland. Terumo launched the product in these six countries in December 2016.

In August 2020, we announced an initial collaboration with Terumo to exclusively sell CytoSorb to hospitals in ten U.S. COVID-19 hotspot states including Alabama, Arizona, California, Georgia, Louisiana, Mississippi, New Mexico, Oregon, Texas, and Washington. CytoSorb previously received Emergency Use Authorization (EUA) by the U.S. Food and Drug Administration (FDA) for use in adult, critically-ill COVID-19 patients with imminent or confirmed respiratory failure. Under the initial terms of the agreement, Terumo will ensure hospitals in the defined hot-spot states have access to the CytoSorb therapy for use in critically-ill COVID-19

patients that meet strict criteria under CytoSorbents' EUA. CytoSorbents will provide all primary clinical and technical training, customer support, and product fulfillment.

In March 2017, we announced a partnership with Dr. Reddy’s Laboratories to exclusively distribute CytoSorb in South Africa for multiple applications. In December 2019, we discontinued this partnership.

In March 2021, we announced a strategic partnership with B. Braun Avitum AG, and the launch of a global co-marketing agreement to promote the use of CytoSorb with B Braun’s latest OMNI® continuous blood purification platform and OMNIset® Plus bloodline set (set version 3.0 or higher).

We continuously evaluate other potential distributor and strategic partner networks in other countries where we are approved to market the device.

Concurrent with our commercialization plans, we intend to conduct or support additional clinical studies in sepsis, cardiac surgery, and other critical care diseases to generate additional clinical data to expend the scope of clinical experience for marketing purposes, to increase the number of treated patients, and to support potential future publications. We have completed a single arm, dose ranging trial in Germany amongst several clinical trial sites supporting the safety and efficacy of CytoSorb when used 24 hours per day for seven days, each day with a new device.

In addition, we now have more than 50 investigator-initiated studies planned, enrolling or completed in many countries such as Germany, Austria, Switzerland, the Netherlands, Hungary, the United Kingdom, India, and the U.S. These trials, which are funded and supported by well-known university hospitals and KOLs, are post-market clinical studies. They have provided and are expected to continue to provide invaluable information regarding the success of the device in the treatment of sepsis, cardiac surgery, liver failure, and many other indications, and if successful, will be integral in helping to drive additional usage and adoption of CytoSorb.

In February 2015, the U.S. Food and Drug Administration (the “FDA”) approved our Investigational Device Exemption (“IDE”) application to commence a planned U.S. cardiac surgery feasibility study called REFRESH I (REduction of FREe Hemoglobin) amongst 20 patients and three U.S. clinical sites. The FDA subsequently approved an amendment to the protocol, expanding the study to a 40-patient randomized controlled study (20 treatment, 20 control) in eight clinical centers. REFRESH I represented the first part of a larger clinical trial strategy intended to support the approval of CytoSorb in the U.S. for intra-operative use during cardiac surgery.

The REFRESH I study was designed to evaluate the safety and feasibility of CytoSorb when used intra-operatively with a heart-lung machine to reduce plasma free hemoglobin (pfHb) and cytokines in patients undergoing complex cardiac surgery. The study was not powered to measure effect on clinical outcomes. The length, complexity and invasiveness of these procedures cause hemolysis and inflammation, leading to high levels of plasma free hemoglobin, cytokines, activated complement, and other substances. These inflammatory mediators are correlated with the incidence of serious post-operative complications such as kidney injury, renal failure and other organ dysfunction. The goal of CytoSorb is to actively remove these inflammatory and toxic substances as they are being generated during the surgery and reduce complications. Enrollment was completed with 46 patients. A total of 38 patients were evaluable for pfHb and completed all aspects of the study.

The primary safety and efficacy endpoints of the study were the assessment of serious device related adverse events and the change in plasma free hemoglobin levels, respectively. On October 5, 2016, we announced positive top-line safety data. In addition, following a detailed review of all reported adverse events in a total of 46 enrolled patients, the independent Data Safety Monitoring Board (“DSMB”) found no serious device related adverse events with the CytoSorb device, achieving the primary safety endpoint of the study. In addition, the therapy was well-tolerated and technically feasible, implementing easily into the cardiopulmonary bypass circuit without the need for an additional external blood pump. The REFRESH I study represented the first randomized controlled study demonstrating the safety of intra-operative CytoSorb use in patients undergoing high risk cardiac operations.

Investigators of the REFRESH I study submitted an abstract with data, including free hemoglobin data, from the REFRESH I study which was selected for a podium presentation at the American Association of Thoracic Surgery conference on May 1, 2017. On May 5, 2017, we announced additional REFRESH I data, including data from the study on the reduction of pfHb and activated complement, and in May 2019, the manuscript of the REFRESH I study was electronically published in the journal, Seminars in Thoracic and Cardiovascular Surgery.

In December 2017, the FDA approved our IDE application for our REFRESH 2-AKI study, permitting us to conduct this pivotal study designed to provide the key safety and efficacy data needed to support United States regulatory approval for CytoSorb in cardiac surgery, which we plan to pursue via the premarket approval (PMA) pathway. The REFRESH 2-AKI study is a randomized,

Table of Contents

controlled, multi-center, clinical study designed to evaluate intraoperative use of two CytoSorb devices as a therapy to reduce the incidence and severity of AKI, as measured by Kidney Disease Improving Global Outcomes (KDIGO) criteria, following complex cardiac surgery. Postoperative AKI following cardiac surgery is common and is associated with higher mortality, and is a risk factor for developing chronic kidney disease requiring hemodialysis in the future. The study will enroll up to 400 patients at increased risk of cardiovascular surgery-associated AKI, undergoing elective, non-emergent open-heart surgery for either valve replacement, or aortic reconstruction with hypothermic cardiac arrest. In April 2018, we announced the first patient enrollment into the pivotal U.S. REFRESH 2-AKI study. Based on the recommendations of key clinical advisors, a protocol amendment was submitted to the FDA on July 19, 2018 to improve operational aspects of the patient screening process and expand the inclusion criteria. It was the preference of clinical trial sites to defer enrollment until the amendment was approved by the FDA, announced in September 2018. On November 25, 2019 the Company announced a pause in enrollment for the REFRESH 2-AKI study. The study’s Data Monitoring Committee (the “DMC”) recommended this pause following a blinded, interim, milestone review of clinical study data. The DMC requested that additional clinical data and data analysis, not pre-specified in the current version of the protocol, be provided by Company. In addition, the Company appointed NAMSA as the new contract research organization (“CRO”) for the study to improve the monitoring of patient safety endpoints. As of November 25, 2019, the study had enrolled 153 patients at 25 initiated sites. Since then, the Company and its new CRO have completed a comprehensive program to re-monitor existing data, collect new data, and analyze the safety data from the 153 patients included in the trial to date. These data were reviewed by the DMC resulting in a favorable opinion on safety, dated July 24, 2020, and the recommendation to resume the trial with only minor modifications.The Company has been undertaking multiple activities in preparation to resume the study, which is estimated to take place in the first half of 2021. If the study is successful, we plan to submit a PMA application to the FDA in 2023 for U.S. regulatory approval.

The German government, via the German Federal Ministry of Education and Research, is funding a 250 patient, multi-center randomized, controlled study (“REMOVE”) using CytoSorb during valve replacement open heart surgery in patients with infective endocarditis. The study enrolled its first patient in January 2018. An interim analysis of the first 50 patients has been completed. On February 4, 2019, Prof. Dr. med. Frank Brunkhorst, Director of the Center for Clinical Studies at Jena University Hospital, who is providing management and oversight to the REMOVE study, and Prof. Dr. med. Torsten Doenst, Director of the Clinic for Cardiac and Thoracic Surgery at the University of Jena, provided the following joint statement, “The Scientific Advisory Board (SAB) of the Center of Sepsis Control and Care (CSCC) and the Data Safety Monitoring Board (DSMB) of the REMOVE study recommended continuation of the study, based upon results of a pre-specified interim analysis that analyzed cytokine and vasoactive mediator levels as an indicator of the mechanistic mode of action of the device in 28 CytoSorb-treated patients and 22 control patients. There were no device-associated adverse events in the CytoSorb group.” The study completed enrollment in 2020 but the COVID-19 pandemic has caused delays in data monitoring and data analysis. Topline data are expected to be reported in the first half of 2021 with full data presentation at a major international conference also in 2021.

In September 2019, a new publication entitled, "Hemoadsorption with CytoSorb showed a decreased observed versus expected 28-day all-cause mortality in ICU patients with septic shock: a propensity-score-weighted retrospective study," in the journal Critical Care. In this study, clinical researchers at Maasstad Hospital and at Erasmus University Medical Center in Rotterdam, Netherlands conducted a retrospective evaluation of 116 patients with septic shock, who required vasopressors to increase their blood pressure, and renal replacement therapy (RRT) due to kidney failure. Of these, 49 patients received standard of care therapy, and 67 were treated with standard of care plus CytoSorb. Both groups were compared by stabilized Inverse Probability of Treatment Weights (sIPTW) to overcome baseline differences in the type of sepsis, age, comorbidities, surgery vs no surgery, Sequential Organ Failure Assessment (SOFA) score, use of the vasopressor noradrenaline, and lactate levels. Patients treated with standard of care and CytoSorb had a statistically significant reduction in 28-day all-cause mortality compared to standard of care alone (53% vs 72% control, p<0.04), based on the sIPTW analysis. In addition, observed 28-day all-cause mortality in the CytoSorb treatment group was significantly lower than the predicted mortality (48% observed vs 75% predicted, p<0.001), based on SOFA score.

In October 2019, CytoSorbents initiated TISORB (Ticagrelor CytoSorb Hemoadsorption), a Company-sponsored, multicenter study in the United Kingdom to prospectively evaluate the removal of ticagrelor during cardiopulmonary bypass in patients on ticagrelor undergoing emergent cardiothoracic surgery. A protocol amendment was submitted to expand the population of eligible patients to now include patients requiring urgent cardiac surgery. These changes were approved by the UK Medicines and Healthcare products Regulatory Agency (MHRA) at the end of February 2020. In December 2020, CytoSorbents initiated CYTATION (CytoSorb Ticagrelor Hemoadsorption), a Company-sponsored multicenter study in Germany to prospectively evaluate the removal of ticagrelor during cardiopulmonary bypass in patients on ticagrelor undergoing emergent cardiothoracic surgery. Ticagrelor (Brilinta®, Astra Zeneca) is a potent platelet inhibitor and antithrombotic therapy and recognized as a standard of care to reduce the risk of heart attacks and strokes in patients with acute coronary syndromes. Unfortunately, given the absence of an approved treatment to reverse the antithrombotic effects of ticagrelor, treated patients who require urgent or emergent cardiothoracic surgery may either proceed at high risk for severe perioperative bleeding (as high as 65% higher risk due to ticagrelor) or stay waiting for days in the hospital until the ticagrelor antithrombotic effect washes out. Neither option is optimal since patients proceeding to surgery are at great risk for serious or even fatal

bleeding and patients waiting for washout are at risk of a thrombotic complications such as a stroke or heart attack, while delaying surgery and increasing hospitalization costs. The benefits of CytoSorb in this setting are both clinical and economic. In the publication in 2019 by Hassan et al, outcomes of 55 patients requiring emergent cardiac surgery while on ticagrelor or rivaroxaban therapy were evaluated according to the use of CytoSorb. Antithrombotic (either ticagrelor or rivaroxaban) removal with CytoSorb was associated with significant reductions in operative time, need for red blood cell and platelet transfusions and re-operations to control bleeding and those clinical benefits resulted in shorter length of ICU stay. These significant clinical benefits are expected to also result in substantial economic benefits. This was demonstrated in the publication by Javanbakht et al. in 2019, that projected an average cost savings of £3,982 per patient (approximately $5,000 USD per patient), including the cost of the CytoSorb adsorber. The primary objective in both TISORB and CYTATION studies is the change in platelet reactivity and ticagrelor blood concentration before and after cardiopulmonary bypass for patients undergoing CytoSorb hemoadsorption removal of ticagrelor from their blood. Due to the COVID-19 pandemic, the execution of the TISORB trial has been greatly impacted and ongoing national restrictions in the U.K. on the conduct of non-COVID clinical studies add further uncertainty to TISORB. In Germany, however, clinical research is continuing and we therefore expect that the CYTATION study will not be equally impacted.

In January 2020, CytoSorb received European Union CE Mark label expansion to include the removal of ticagrelor during cardiopulmonary bypass in patients undergoing cardiothoracic surgery. In May 2020, CytoSorb also received European Union CE Mark label expansion to include rivaroxaban removal for the same indication. We have recently announced the Safe and Timely Antithrombotic Removal (STAR) development program that will comprise of a number of clinical projects relating to the antithrombotic removal application. The first study is the STAR Registry scheduled to commence enrollment in 2021 that will capture real world use of CytoSorb for this indication. The registry will initially launch in Europe with the intent of expanding to the United States and the rest of the territories where CytoSorb is available in the future. We anticipate that additional clinical studies on antithrombotic removal will be conducted as part of the STAR program.

The market focus of CytoSorb is the prevention or treatment of organ failure in life-threatening conditions, including commonly seen illnesses in the ICU such as infection and sepsis, trauma, burn injury, ARDS, and others. Severe sepsis and septic shock, a potentially life-threatening systemic inflammatory response to a serious infection, accounts for approximately 10% to 20% of all ICU admissions and is one of the largest target markets for CytoSorb. Sepsis is a major unmet medical need with no approved products in the U.S. or Europe to treat it. As with other critical care illnesses, multiple organ failure is the primary cause of death in sepsis. When used with standard of care therapy, that includes antibiotics, the goal of CytoSorb in sepsis is to reduce the excessive levels of cytokines and other inflammatory toxins, to help reduce the SIRS response and either prevent or treat organ failure.

We intend to conduct or support additional clinical studies in sepsis, cardiac surgery, and other critical care diseases where CytoSorb could be used, such as ARDS, liver disease, severe burn injury, acute pancreatitis, and other acute conditions that may benefit by the reductions of cytokines in the bloodstream. Some examples include the prevention of post-operative complications of cardiac surgery (cardiopulmonary bypass surgery) and damage to organs for transplant prior to organ harvest. We intend to generate additional clinical data to expand the scope of clinical experience for marketing purposes, to increase the number of treated patients, and to support potential future publications.

Our proprietary polymer technologies form the basis of a broad technology portfolio. Some of our products and product candidates include:

●ECOS-300CY - an adsorption cartridge for use with ex vivo organ perfusion systems to remove cytokines and other inflammatory mediators in the organ perfusate, with the goal of improving solid organ support or rehabilitation.

●VetResQ — a broad spectrum blood purification adsorber designed to help treat deadly inflammation and toxic injury in animals with critical illnesses such as septic shock, toxic shock syndrome, severe systemic inflammation, toxin-mediated diseases, pancreatitis, trauma, liver failure, and drug intoxication. VetResQ is being commercialized in the United States.

●ContrastSorb—a development-stage extracorporeal hemoperfusion cartridge designed to remove IV contrast from the blood of high risk patients undergoing radiological imaging with contrast, or interventional radiology procedures such as cardiac catheterization and angioplasty. The goal of ContrastSorb is to prevent contrast-induced nephropathy.

●DrugSorb—a development-stage extracorporeal hemoperfusion cartridge designed to remove toxic chemicals from the blood (e.g., drug overdose, high dose regional chemotherapy).

●BetaSorb—a development-stage extracorporeal hemoperfusion cartridge designed to remove mid-molecular weight toxins, such as b2-microglobulin, that standard high-flux dialysis cannot remove effectively. The goal of BetaSorb is to improve the efficacy of dialysis or hemofiltration.

We have been successful in obtaining technology development contracts from governmental agencies such as the National Institutes of Health and the U.S. Department of Defense, including the Defense Advanced Research Projects Agency, or DARPA, the U.S. Army, U.S. Special Operations Command, and others.

Results of Operations

Comparison of the year ended December 31, 2020 and 2019

Revenues:

For the year ended December 31, 2020, we generated total revenue, which includes product revenue and grant income, of approximately $41,005,000 as compared to revenues of approximately $24,949,000 for the year ended December 31, 2019, an increase of approximately $16,056,000, or 64%. Revenue from product sales was approximately $39,453,000 for the year ended December 31, 2020, as compared to approximately $22,766,000 in the year ended December 31, 2019, an increase of approximately $16,787,000 or 73%. This increase was driven by an increase in direct sales of approximately $8,917,000 resulting from sales to both new customers and repeat orders from existing customers and an increase in distributor sales of approximately $7,769,000. Sales to hospitals in the United States under the EUA granted by the FDA amounted to approximately $1,341,000 for the year ended December 31, 2020. Though difficult to quantitate, we estimate that approximately $9.4 million of total product sales during the year ended December 31, 2020 was due to the demand for CytoSorb to treat COVID-19 patients. In addition, as a result of the increase in the average exchange rate of the Euro to the U.S. dollar, sales were positively impacted by approximately $693,000. For the year ended December 31, 2020, the average exchange rate of the Euro to the U.S. dollar was $1.14 as compared to an average exchange rate of $1.12 for the year ended December 31, 2019.

Cost of Revenue:

For the years ended December 31, 2020 and 2019, cost of revenue was approximately $11,052,000 and $7,364,000, respectively, an increase of approximately $3,688,000. Product cost of revenues increased approximately $4,180,000 during the year ended December 31, 2020 as compared to the year ended December 31, 2019 as a result of the increase in product sales. Product gross margins were approximately 76% for the year ended December 31, 2020 and approximately 77% for the year ended December 31, 2019. The decrease in gross margin was due to an increase in percent contribution of lower margin distributor sales as well as certain costs associated with the rapid ramp-up of production during the year ended December 31, 2020.

Gross Profit:

Gross profit was approximately $29,952,000 for the year ended December 31, 2020, an increase of approximately $12,366,000 or 70%, over gross profit of $17,586,000 in 2019. This increase is attributed to an increase in CytoSorb product sales during 2020.

Research and Development Expenses:

Our research and development costs were approximately $8,811,000 and $12,092,000 for the years ended December 31, 2020 and 2019, respectively, a decrease of approximately $3,281,000, or 27%. This decrease was due to a decrease in clinical trial and related costs of approximately $3,769,000, due primarily to the pause in our Company-sponsored clinical trials as a result of hospital restrictions due to the COVID-19 pandemic, and a decrease in our non-grant related research and development costs of approximately $393,000.

These decreases were offset by an increase in non-clinical research and development salary related costs of approximately $160,000 due primarily to COVID-19 related incentive pay, decreases in direct labor and other costs being deployed toward grant-funded activities of approximately $675,000, which had the effect of increasing the amount of our non-reimbursable research and development costs and an increase in new product development costs of approximately $46,000.

Legal, Financial and Other Consulting Expenses:

Our legal, financial and other consulting costs were approximately $3,048,000 and $2,462,000 for the years ended December 31, 2020 and 2019, respectively, an increase of approximately $586,000, or 24%. This increase was due to an increase in employment agency fees of approximately $395,000 related to the hiring of senior level personnel, an increase in consulting fees of approximately $219,000 primarily related to certain financial advisory fees and an increase in accounting and auditing fees of approximately $40,000. These increases were offset by a decrease in legal fees of approximately $70,000.

Selling, General and Administrative Expenses:

Our selling, general and administrative expenses were approximately $28,464,000 and $22,006,000 for the years ended December 31, 2020 and 2019, respectively, an increase of approximately $6,458,000, or 29%. This increase was due to an increase in salaries, commissions and related costs of approximately $4,849,000 due primarily to headcount additions and increased commissions due to increase sales, an increase in royalty expenses of approximately $1,327,000 due to the increase in product sales, and an increase in non-cash stock option expense of approximately $1,879,000. These increases were offset by reductions in sales and marketing costs, which include advertising and conference attendance of approximately $824,000 and travel and entertainment and other general and administrative expenses of approximately $773,000. These reductions were due primarily to travel restrictions related to the COVID-19 pandemic.

Interest Expense, Net:

For the year ended December 31, 2020, interest expense, net was approximately $1,201,000, as compared to interest expense, net of approximately $1,034,000 for the year ended December 31, 2019. This increase in net interest expense of approximately $167,000 is related to the final fee that was due upon repayment of our term loans in conjunction with the Third Amendment to the Amended Loan and Security Agreement with Bridge Bank that closed on December 4, 2020.

Gain (Loss) on Foreign Currency Transactions:

For the year ended December 31, 2020, the gain on foreign currency transactions was approximately $2,607,000, as compared to a loss on foreign currency transactions of approximately $350,000 for the year ended December 31, 2019. The 2020 gain is directly related to the increase of the exchange rate of the Euro at December 31, 2020 as compared to December 31, 2019. The exchange rate of the Euro to the U.S. dollar was $1.22 per Euro at December 31, 2020 as compared to $1.12 per Euro at December 31, 2019. The 2019 loss is directly related to the decrease in the exchange rate of the Euro at December 31, 2019, as compared to December 31, 2018. The exchange rate of the Euro to the U.S. dollar was $1.12 per Euro at December 31, 2019 as compared to $1.15 per Euro at December 31, 2018.

Benefit from Income Taxes:

Our benefit from income taxes was approximately $1,127,000 and $1,092,000 for the years ended December 31, 2020 and 2019, respectively. These benefits were realized by utilizing the New Jersey Technology Business Tax Certificate Transfer Program whereby the State of New Jersey allows us to sell a portion of our state net operating losses to a third party.

This increase was offset by a decrease in distributor sales of approximately $680,000. In addition, sales were negatively impacted by approximately $1,201,000 as a result of the decrease in the average exchange rate of the Euro to the U.S. dollar.

Legal, Financial and Other Consulting Expenses:

Our legal, financial and other consulting costs were approximately $2,462,000 and $2,002,000 for the years ended December 31, 2019 and 2018, respectively, an increase of approximately $460,000, or 23%.

This increase was due to an increase in salaries, commissions and related costs of approximately $2,323,000, additional sales and marketing costs, which include advertising and conference attendance of approximately $863,000, an increase in royalty expenses of approximately $198,000 due to the increase in product sales, and an increase in restricted stock expense of approximately $226,000 related to restricted stock units granted to the Company’s executive officers, an increase in public relations cost of approximately $78,000 and increase in other general and administrative costs of approximately $215,000.

For the year ended December 31, 2019, the loss on foreign currency transactions was approximately $350,000, as compared to a loss on foreign currency transactions of approximately $785,000 for the year ended December 31, 2018.

The 2018 loss is directly related to the decrease in the exchange rate of the Euro at December 31, 2018, as compared to December 31, 2017. The exchange rate of the Euro to the U.S. dollar was $1.15 per Euro at December 31, 2018 as compared to $1.20 per Euro at December 31, 2017.

Benefit from Income Taxes:

These benefits were realized by utilizing the New Jersey Technology Business Tax Certificate Transfer Program whereby the State of New Jersey allows us to sell a portion of our state net operating losses to a third party.

History of Operating Losses

We have experienced substantial operating losses since inception. As of December 31, 2020, we had an accumulated deficit of approximately $196,627,000, which included losses of approximately $7,837,000, $19,266,000 and $17,211,000 for years ended December 31, 2020, 2019 and 2018, respectively. Historically, our losses have resulted principally from costs incurred in the research and development of our polymer technology, our legal, financial and consulting expenses, and selling, general and administrative expenses, which together were approximately $40,323,000, $36,560,000 and $30,599,000 for the years ended December 31, 2020, 2019 and 2018, respectively.

Liquidity and Capital Resources

Since inception, our operations have been primarily financed through the private and public placement of our debt and equity securities. At December 31, 2020, we had current assets of approximately $82,453,000 including cash on hand of approximately $71,422,000 and had current liabilities of approximately $10,153,000. During the period from January 1, 2020 through July 15, 2020, we raised approximately $26,427,000 by utilizing our ATM facility with co-agents Jefferies LLC and B. Riley FBR. In addition, we received net proceeds of approximately $53,800,000 from our underwritten public offering that closed on July 24, 2020. Also, we expect to receive approximately $1,127,000 in cash from the approved sale of our net operating losses and research and development credits from the State of New Jersey in the first quarter of 2021.

We believe that we have sufficient cash to fund our operations and clinical trial activities well into the future.

Loan and Security Agreement:

Table of Contents

Security Agreement and the 2018 Success Fee Letter (the “2018 Letter”). In connection with the execution of the First Amendment, the draw period for the Term B Loan was extended to August 15, 2019 and the Company drew down the full $5.0 million Term B Loan on the Settlement Date, bringing the total outstanding debt to $15,000,000 at July 31, 2019. The proceeds of Term Loans were used for general business requirements in accordance with the Amended and Restated Loan and Security Agreement. On December 4, 2020 (the “Closing Date”), the Company closed on the Third Amendment (the “Third Amendment”) of its Amended Loan and Security Agreement with Bridge Bank. Under the terms of the Amendment, the Company repaid the outstanding principal balance of its existing $15 million term loans and simultaneously received a commitment from Bridge Bank to provide a new term loan of $15 million (the “New Term Loan”), which can be drawn down at the Company’s discretion at any time prior to December 4, 2021.

The New Term Loan, if drawn, shall bear interest at the Index Rate (defined in the Third Amendment as the greater of 3.25% or the Prime Rate as published by the Wall Street Journal on the last business date of the month the immediately preceding the month in which the interest will accrue) plus 1.25%. In addition, the Company would be required to make payments of interest-only commencing on the first day of the month after the New Term Loan was made until January 2023. The interest-only period may be further extended through July 2023 if the Company maintains compliance certain conditions as outlined in the Amendment. Following the interest-only period, the Company will be required to make equal monthly payments of principal and interest until maturity of the New Term Loan. The maturity date of the New Term Loan is December 1, 2024.

On the Closing Date, the Company was required to pay a non-refundable closing fee of $75,000. As of the Closing Date, the total unamortized loan costs related to the Term Loans amounted to approximately $45,000. These costs were written off on the closing date as a charge to interest expense. For the years ended December 31, 2020, 2019, and 2018, the Company recorded interest expense amounting to $76,718, $33,175, and $31,946, respectively related to these costs. In addition, the Amended and Restated Loan and Security Agreement requires the Company to pay a non-refundable final fee equal to 2.5% of the principal amount of each Term Loan funded upon the earlier of the (i) April 1, 2022 maturity date or (ii) termination of the Term Loan via acceleration or prepayment. On the Closing Date, the Company paid a final fee of $325,000. For the years ended December 31, 2020, 2019 and 2018 the Company recorded interest expense of $246,095, $82,031 and $65,104, respectively, related to accrual and payment of the final fee.

The Company’s and CytoSorbents Medical, Inc.’s obligations under the Amended and Restated Loan and Security Agreement are joint and severable and are secured by a first priority security interest in favor of the Bank with respect to the Company’s Shares (as defined in the Amended and Restated Loan and Security Agreement) and the Borrower’s Collateral (as defined in the Amended and Restated Loan and Security Agreement, which definition excludes the Borrower’s intellectual property and other customary exceptions).

2018 Success Fee Letter:

Pursuant to the amended 2018 Letter, the Borrower shall pay to the Bank a success fee in the amount equal to 6.37% of the funded amount of the Term B Loan (as defined in the Restated Loan and Security Agreement) (the “Success Fee”) upon the first occurrence of any of the following events: (a) a sale or other disposition by the Borrower of all or substantially all of its assets; (b) a merger or consolidation of the Borrower into or with another person or entity, where the holders of the Borrower’s outstanding voting equity securities as of immediately prior to such merger or consolidation hold less than a majority of the issued and outstanding voting equity securities of the successor or surviving person or entity as of immediately following the consummation of such merger or consolidation; (c) a transaction or a series of related transactions in which any “person” or “group” (within the meaning of Section 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of a sufficient number of shares of all classes of stock then outstanding of the Borrower ordinarily entitled to vote in the election of directors, empowering such “person” or “group” to elect a majority of the Board of Directors of the Borrower, who did not have such power before such transaction; or (d) the closing price per share for the Company’s common stock on the Nasdaq Capital Market being the greater of (i) 70% or more over $7.05, the closing price of the Company’s common stock on March 29, 2018 (after giving effect to any stock splits or consolidations effected after the date thereof) for five successive business days, or (ii) at least 26.13% more than the average price of Company’s common stock for the 365 day period ending on the date of the funding of the Term B Loan. This obligation shall terminate on the fifth anniversary of the funding of the Term B Loan and shall survive the termination of the loan agreement and the prepayment of the Term B Loan.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the

Table of Contents

reporting period. Actual results could differ from those estimates. We believe the following critical accounting policies and estimates have significant effect in the preparation of our consolidated financial statements.

Patents

Legal costs incurred to establish patents are capitalized. When patents are issued, capitalized costs are amortized on the straight-line method over the related patent term. In the event a patent is abandoned, the net book value of the patent is written off.

Revenue Recognition

Product Sales: Revenues from sales of products to both direct and distributor/strategic partner customers are recognized at the time when control passes to the customer, in accordance with the terms of their respective contracts. Recognition of revenue occurs as each performance obligation is completed.

Grant Revenue: Revenue from grant income is based on contractual agreements. Certain agreements provide for reimbursement of costs, other agreements provide for reimbursement of costs and an overhead margin and certain agreements are performance based, where revenue is earned based upon the achievement of milestones outlined in the contract. Revenues are recognized when the associated performance obligation is fulfilled. Costs are recorded as incurred. Costs subject to reimbursement by these grants have been reflected as costs of revenue.

Research and Development

All research and development costs, payments to laboratories, research consultants and costs related to clinical trials and studies are expensed when incurred.

Stock Based-Compensation

We account for our stock-based compensation under the recognition requirements of accounting standards for accounting for stock-based compensation for employees and directors whereby each option granted is valued at fair market value on the date of grant. Under these accounting standards, the fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model.

We also follow the guidance of accounting standards for accounting for equity instruments that are issued to other than employees for acquiring, or in conjunction with selling, goods or services for equity instruments issued to consultants.

Lease Commitments

We currently operate a facility near Princeton, New Jersey with approximately 20,821 sq. ft., housing research laboratories, clinical manufacturing operations and administrative offices, under a lease agreement which expires in May 2021. The lease includes a one year option to renew. We expect to secure additional square footage to support increased manufacturing capacity in the future. Our monthly base rent is approximately $33,600 and, additionally, we reimburse the landlord for monthly operating expenses of approximately $29,700.

We also operate a facility in Berlin, Germany housing our sales and administrative offices and warehouse space. We entered into a lease for this office on September 1, 2016. The lease expires on August 31, 2021. We rent this space for $9,000 per month. In January 2021, we entered to a lease for additional warehouse space in Germany. The lease commences on April 1, 2021, requires monthly payments of base rent and other costs of approximately $7,900 and has a term of five years. The lease also has an option to extend the lease term for an additional five years.

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

We are exposed to certain market risks in the ordinary course of business. These risks result primarily from changes in foreign currency exchange rates and interest rates. In addition, international operations are subject to risks related to differing economic conditions, changes in political climate, differing tax structures and other regulations and restrictions.

To date we have not utilized derivative financial instruments or derivative commodity instruments. We do not expect to employ these or other strategies to hedge market risk in the foreseeable future. Cash is held in checking, savings, and money market funds,

Table of Contents

which are subject to minimal credit and market risk. We generate sales in both dollars and euros most significantly, the majority of our sales are in Euros and changes in the exchange rate of the Euro to the U.S. dollar may positively or negatively impact our revenue. On the other hand, should sales decline due to a devaluation of the Euro relative to the U.S. dollar, expenses related to our European subsidiary would also decline. This produces a natural currency hedge. We believe that the market risks associated with these financial instruments are immaterial, although there can be no guarantee that these market risks will be immaterial to us in the future.

Management’s 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) under the Exchange Act. The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. 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 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. Further, because of changes in conditions, effectiveness of internal control over financial reporting may vary over time. Management, with the participation of the Chief Executive Officer and the Chief Financial Officer, working with an external consultant, conducted an evaluation of the effectiveness of internal control over financial reporting based on the framework in Internal-Control –Integrated Framework issued in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that internal control over financial reporting was effective as of December 31, 2020.

WithumSmith+Brown, PC, the independent registered public accounting firm that audited the Company’s consolidated financial statements included in this Annual Report on Form 10-K, was engaged to audit our Internal Controls. Their report appears on page F-3.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders

Cytosorbents Corporation:

Opinion on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of Cytosorbents Corporation (the "Company") as of December 31, 2020 and 2019, and the related consolidated statements of operations and comprehensive loss, changes in stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2020, based on the 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, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework (2013) issued by the COSO.

Basis for Opinion

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 the accompanying management’s report on internal control over financial reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion 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.

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

F-3

Table of Contents

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 Matter

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

Stock Based Compensation

Description of the Matter

As discussed in Notes 2 and 11 of the consolidated financial statements, the Company grants stock-based awards including stock options, restricted stock units and performance-based stock awards to their employees as compensation for their service. The Company recorded approximately $3,500,000 of stock-based compensation expense during the year ended December 31, 2020. Certain awards include performance conditions that only vest if those conditions are met, and the quantity of awards received can range based on the level performance achieved. In 2020, the Company had 1,114,325 of such awards outstanding, and recorded stock-based compensation expense related to these performance awards of approximately $914,000.

Auditing the Company's accounting for stock-based compensation required complex auditor judgment due to the number and the variety of the types of equity awards, the subjectivity of assumptions used to value stock-based awards and the frequent use of performance-based vesting conditions. In particular, judgment was required to evaluate the nature of the annual performance conditions, as well as to assess the satisfaction of the performance targets.

How we Addressed the Matter in our Audit

Addressing the matter involved obtaining an understanding, evaluating the design and testing the operating effectiveness of controls over the Company’s process for determining stock-based compensation expense, including testing management’s review controls over the underlying calculations, the significant assumptions used in valuing certain awards, identification of the terms of the performance conditions and the key inputs used in determining the outcome of each performance condition. We assessed the appropriateness of judgments made by management in determining key assumptions related to the awards, such as service inception date based on the annual performance conditions. We tested the accuracy of the data used in measuring the awards by agreeing the underlying inputs, such as grant date, grant price, performance targets and vesting terms, among others, back to source documents, such as compensation meeting minutes or award letters. Additionally we tested the related valuation report on volatility prepared by its specialists by involving our internal valuation specialists to assess the valuation methodologies and assumptions used. We determined whether performance targets were satisfied in accordance with the contractual conditions, and recalculated grant date fair value by multiplying the awarded quantity of awards by the grant price. We also evaluated the adequacy of the Company’s stock-based compensation disclosures included in Notes 2 and 11 in relation to these matters.

/s/ WithumSmith+Brown, PC

We have served as the Company’s auditor since 2004.

Notes to Consolidated Financial Statements

1. BASIS OF PRESENTATION

The accompanying consolidated financial statements include the results of CytoSorbents Corporation (the “Parent”), CytoSorbents Medical Inc., its wholly-owned operating subsidiary (the “Subsidiary”), and CytoSorbents Europe GmbH, its wholly-owned European subsidiary (the “European Subsidiary”). In addition, the consolidated financial statements include CytoSorbents Switzerland GmbH and CytoSorbents Poland Sp. z.o.o., wholly owned subsidiaries of CytoSorbents Europe GmbH, and CytoSorbents UK Limited, a wholly-owned subsidiary of CytoSorbents Medical, Inc. These entities are collectively referred to as “the Company”.

In years prior to December 31, 2020, the Company’s consolidated financial statements were prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. On July 24, 2020, the Company closed an underwritten public offering of 6,052,631 shares of its common stock at a public offering price of $9.50 per share (the “Offering”). Gross proceeds from the Offering amounted to approximately $57.5 million and, after deducting the underwriting discounts and commissions and expenses related to the Offering, the Company received total net proceeds of approximately $53.8 million. See Note 11. As of December 31, 2020, the Company’s cash balance was approximately $71.4 million, which the Company expects will fund the Company’s operations well beyond the next twelve months. As a result, the Company has determined that the going concern risk has been substantially mitigated.

2. PRINCIPAL BUSINESS ACTIVITY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Nature of Business

The Company is a leader in critical care immunotherapy using blood purification technology to treat deadly inflammation in critically-ill and cardiac surgery patients around the world. The Company, through its subsidiary CytoSorbents Medical, Inc. (formerly known as CytoSorbents, Inc.), is engaged in the research, development and commercialization of medical devices with its blood purification technology platform which incorporates a proprietary adsorbent, porous polymer technology. The Company, through its wholly owned European subsidiary, CytoSorbents Europe GmbH, conducts sales and marketing related operations for the CytoSorb device. In March 2016, the Company formed CytoSorbents Switzerland GmbH, a wholly-owned subsidiary of CytoSorbents Europe GmbH. This subsidiary, which began operations during the second quarter of 2016, provides marketing and direct sales services in Switzerland. In November 2018, the Company formed CytoSorbents Poland Sp. z.o.o., a wholly-owned subsidiary of CytoSorbents Europe GmbH. This subsidiary, which began operations during the first quarter of 2019, provides marketing and direct sales services in Poland. In the third quarter of 2019, the Company formed CytoSorbents UK Limited, a wholly-owned subsidiary of CytoSorbents Medical, Inc. which is responsible for the management of our clinical trial activities in the United Kingdom.

Table of Contents

CytoSorb, the Company's flagship product, was approved in the European Union (“EU”) in March 2011, and is currently being marketed and distributed in sixty-seven countries around the world, as a safe and effective extracorporeal cytokine absorber, designed to reduce the “cytokine storm” that could otherwise cause massive inflammation, organ failure and death in common critical illnesses such as sepsis, burn injury, trauma, lung injury, and pancreatitis. In May 2018, the Company received a label extension for CytoSorb covering use of the device for the removal of bilirubin and myoglobin which allows for the use of the device in the treatment of liver failure and trauma, respectively. CytoSorb is also being used during and after cardiac surgery to remove inflammatory mediators, such as cytokines and free hemoglobin, which can lead to post-operative complications, including multiple organ failure. In January 2020, CytoSorb received European Union CE Mark label expansion to include the removal of ticagrelor during cardiopulmonary bypass in patients undergoing cardiothoracic surgery. In May 2020, CytoSorb also received European Union CE Mark label expansion to include rivaroxaban removal for the same indication.

The technology is based upon biocompatible, highly porous polymer sorbent beads that can actively remove toxic substances from blood and other bodily fluids by pore capture and surface adsorption. The Company has numerous products under development based upon this unique blood purification technology, which is protected by 16 issued U.S. patents and multiple international patents, with applications pending both in the U.S. and internationally, including HemoDefend, ContrastSorb, DrugSorb, and others. These patents and patent applications are directed to various compositions and methods of use related to our blood purification technologies and are expected to expire between 2021 and 2035, absent any patent term extensions. Management believes that any near-term expiring patents will not have a significant impact on our ongoing business.

Stock Market Listing

On December 17, 2014 the Company’s common stock was approved for listing on The Nasdaq Capital Market (“Nasdaq”), and it began trading on Nasdaq on December 23, 2014 under the symbol “CTSO”. Previously, the Company’s common stock traded in the over-the-counter-market on the OTC Bulletin Board.

Basis of Consolidation and Foreign Currency Translation

The consolidated financial statements include the accounts of CytoSorbents Corporation and its wholly-owned subsidiaries, CytoSorbents Medical, Inc. and CytoSorbents Europe GmbH. In addition, the consolidated financial statements include CytoSorbents Switzerland GmbH and CytoSorbents Poland Sp. z.o.o., wholly owned subsidiaries of CytoSorbents Europe GmbH, and CytoSorbents UK Limited, a wholly-owned subsidiary of CytoSorbents Medical, Inc. All significant intercompany transactions and balances have been eliminated in consolidation.

Translation gains and losses resulting from the process of remeasuring into the United States of America dollar, the foreign currency financial statements of the European subsidiary, for which the United States of America dollar is the functional currency, are included in operations. Foreign currency transaction gain (loss) included in net loss amounted to approximately $2,607,000, $(350,000) and $(785,000) for the years ended December 31, 2020, 2019 and 2018, respectively. The Company translates assets and liabilities of the European subsidiary, whose functional currency is their local currency, at the exchange rate in effect at the balance sheet date. The Company translates revenue and expenses at the daily average exchange rates. The Company includes accumulated net translation adjustments in accumulated other comprehensive income (loss) as a component of stockholder’s equity.

Table of Contents

Cash and Cash Equivalents

The Company considers all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents.

Grants and Accounts Receivable

Grants receivable represent amounts due from U.S. government agencies and are included in Grants and Accounts Receivable.

Accounts receivable are unsecured, non-interest bearing customer obligations due under normal trade terms. The Company sells its devices to various hospitals and distributors. The Company performs ongoing credit evaluations of customers’ financial condition. Management reviews accounts receivable periodically to determine collectability. Balances that are determined to be uncollectible are reserved for to the allowance for doubtful accounts.

Inventories

Inventories are valued at the lower of cost or net realizable value. Cost is determined using a first-in first-out (“FIFO”) basis. At December 31, 2020 and 2019, the Company’s inventory was comprised of finished goods, which amounted to $1,164,635 and $305,452, respectively, work in process which amounted to $1,222,062 and $1,523,923, respectively and raw materials which amounted to $287,102 and $284,522, respectively. Devices used in clinical trials or for research and development purposes are removed from inventory and charged to research and development expenses at the time of their use.

Property and Equipment

Property and equipment are recorded at cost less accumulated depreciation. Depreciation of property and equipment is provided for by the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the lesser of their economic useful lives or the term of the related leases. Gains and losses on depreciable assets retired or sold are recognized in the statements of operations in the year of disposal. Repairs and maintenance expenditures are expensed as incurred.

Patents

Impairment or Disposal of Long-Lived Assets

The Company assesses the impairment of patents and other long-lived assets under accounting standards for the impairment or disposal of long-lived assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. For long-lived assets to be held and used, the Company recognizes an impairment loss only if its carrying amount is not recoverable through its undiscounted cash flows and measures the impairment loss based on the difference between the carrying amount and fair value.

Revenue Recognition

Grant Revenue: Revenue from grant income is based on contractual agreements. Certain agreements provide for reimbursement of costs, other agreements provide for reimbursement of costs and an overhead margin and certain agreements are performance based, where revenue is earned based upon the achievement of milestones outlined in the contract. Revenues are recognized when the associated performance obligation is fulfilled. Costs are recorded as incurred. Amounts invoiced in excess of costs actually incurred on fixed price contracts are classified as deferred revenue. Costs subject to reimbursement by these grants have been reflected as costs of revenue.

F-11

Table of Contents

Research and Development

All research and development costs, payments to laboratories, research consultants and costs related to clinical trials and studies are expensed when incurred.

Advertising Expenses

Advertising costs are charged to activities when incurred. Advertising expense amounted to approximately $285,000, $314,000 and $212,000 in 2020, 2019 and 2018, respectively, and is included in selling, general, and administrative expenses on the consolidated statements of operations and comprehensive loss.

Income Taxes

Income taxes are accounted for under the asset and liability method prescribed by accounting standards for accounting for income taxes. Deferred income taxes are recorded for temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities. Deferred tax assets and liabilities reflect the tax rates expected to be in effect for the years in which the differences are expected to reverse. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax asset will not be realized. Under Section 382 of the Internal Revenue Code the net operating losses generated prior to the previously completed reverse merger may be limited due to the change in ownership. Additionally, net operating losses generated subsequent to the reverse merger may be limited in the event of changes in ownership. The Tax Cuts and Jobs Act reduced the U.S. federal corporate tax rate from 35% to 21%. See Note 9 for the impact of the tax rate change on deferred tax assets and liabilities.

The Company follows the accounting standards associated with uncertain tax provisions. The Company had no unrecognized tax benefits at December 31, 2020 or 2019. The Company files tax returns in the U.S. federal and state jurisdictions.

The Company utilizes the Technology Business Tax Certificate Transfer Program to sell a portion of its New Jersey Net Operating Loss tax carryforwards and Research and Development credits to an industrial company.

CytoSorbents Europe GmbH, CytoSorbents Switzerland GmbH, CytoSorbents Poland Sp. z.o.o. and CytoSorbents UK Limited files an annual corporate tax return, a VAT return and a trade tax return in Germany, Switzerland, Poland and the United Kingdom, respectively.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities. Actual results could differ from these estimates. The valuation of options granted is a significant estimate in these consolidated financial statements.

Concentration of Credit Risk

The Company maintains cash balances, at times, with financial institutions in excess of amounts insured by the Federal Deposit Insurance Corporation. Management monitors the soundness of these institutions in an effort to minimize its collection risk of these balances.

A significant portion of our revenues are from product sales in Germany. Substantially all of our grant and other income are from grant agencies in the United States. (See Note 3 for further information relating to the Company’s revenue.)

As of December 31, 2020 and 2019, no agency, distributor/strategic partners or direct customer represented more than 10%of outstanding grants and accounts receivables. For the years ended December 31, 2020, 2019 and 2018 no agency, distributor/strategic partners or direct customer represented more than 10% of the Company’s total revenue.

Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses and other current liabilities approximate their fair values due to their short-term nature.

F-12

Table of Contents

Net Loss per Common Share

Basic earnings per share is computed by dividing loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share is computed using the treasury stock method on the basis of the weighted-average number of shares of common stock plus the dilutive effect of potential common shares outstanding during the period. Dilutive potential common shares include outstanding warrants, stock options and restricted shares. The computation of diluted earnings per share does not assume conversion, exercise or contingent exercise of securities that would have an anti-dilutive effect on earnings (See Note 12).

Stock-Based Compensation

The Company accounts for its stock-based compensation under the recognition requirements of accounting standards for accounting for stock-based compensation for employees and directors whereby each option granted is valued at fair market value on the date of grant. Under these accounting standards, the fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model.

The Company also follows the guidance of accounting standards for accounting for equity instruments that are issued to non-employees for acquiring, or in conjunction with selling, goods or services for equity instruments issued to consultants.

Shipping and Handling Costs

The cost of shipping product to customers and distributors is typically borne by the customer or distributor. The Company records shipping and handling costs in cost of revenue. Total freight costs amounted to approximately $560,000, $476,000 and $424,000 for the years ended December 31, 2020, 2019 and 2018, respectively.

Product sales:

Grant and other income:

The Company has two primary revenue streams: (1) sales of the CytoSorb device and related device accessories and (2) grant income from contracts with various agencies of the United States government. Both of these revenue streams are within the scope of this accounting pronouncement. The following is a brief description of each revenue stream.

CytoSorb Sales

The Company sells its CytoSorb device using both its own sales force (direct sales) and through the use of distributors and/or strategic partners. The majority of sales of the device are outside the United States, as CytoSorb is not yet approved for commercial sale in the United States. However, in April 2020, the Company was granted Emergency Use Authorization (“EUA”) of CytoSorb for use in critically-ill patients infected with COVID-19 by the United States Food and Drug Administration (the “FDA”). Direct sales outside the United States relate to sales to hospitals located in Germany, Switzerland, Austria, Belgium, Luxembourg, Poland, the Netherlands, Sweden, Denmark and Norway. Direct sales are fulfilled from the Company’s office in Berlin, Germany. There are no formal sales contracts with any direct customers relating to product price or minimum purchase requirements. However, there are agreements in place with certain direct customers that provide for either free of charge product or rebate credits based upon achieving minimum purchase levels. The Company records the value of these items earned as a reduction of revenue. These customers submit purchase orders and the order is fulfilled and shipped directly to the customer. Prices to all direct customers are based on a standard price list based on the packaged quantity (6 packs vs 12 packs).

Distributor and strategic partner sales make up the remaining product sales. These distributors are located in various countries throughout the world. The Company has a formal written contract with each distributor/strategic partner. These contracts have terms ranging from 1-5 years in length, with three years being the typical term. In addition, certain distributors are eligible for volume discount pricing if their unit sales are in excess of the base amount in the contract.

Most distributor’s/strategic partner’s contracts have minimum annual purchase requirements in order to maintain exclusivity in their respective territories.

F-14

Table of Contents

There is no additional consideration or monetary penalty that would be required to be paid to CytoSorbents if a distributor does not meet the minimum purchase commitments included in the contract, however, at the discretion of the Company, the distributor may lose its exclusive rights in the territory if such commitments are not met.

Government Grants

The Company has been the recipient of various grant contracts from various agencies of the United States government, primarily the Department of Defense, to perform various research and development activities. These contacts fall into one of the following categories:

In summary, the contracts the Company has with customers are the distributor/strategic partner contracts related to CytoSorb product sales, agreements with direct customers related to free-of-charge product and credit rebates based upon achieving minimum purchase levels, and contracts with various government agencies related to the Company’s grants. The Company does not currently incur any outside/third party incremental costs to obtain any of these contracts. The Company does incur internal costs, primarily salary related costs, to obtain the contracts related to the grants. Company employees spend time reviewing the program requirements and developing the budget and related proposal to submit to the grantor agency. There may additionally be travel expenditures involved with meeting with government agency officials during the negotiation of the contract. These internal costs are expensed as incurred.

The following table provides information about receivables and contract liabilities from contracts with customers:

Contract receivables represent balances due from sales to distributors and amounts invoiced on grant contracts.

Contract liabilities represent the value of free of charge goods and credit rebates earned in accordance with the terms of certain direct customer agreements and deferred grant revenue related to the billing on fixed price contracts in excess of costs incurred as of December 31, 2020 and 2019.

7. LONG-TERM DEBT:

On June 30, 2016, the Company and its wholly-owned subsidiary, CytoSorbents Medical, Inc. (together, the “Borrower”), entered into a Loan and Security Agreement with Bridge Bank, a division of Western Alliance Bank, (the “Bank”), pursuant to which the Company borrowed $10 million in two equal tranches of $5 million (the “Original Term Loans”). On March 29, 2018, the Original Term Loans were refinanced with the Bank pursuant to an Amended and Restated Loan and Security Agreement by and between the Bank and the Borrower (the “Amended and Restated Loan and Security Agreement”), under which the Bank agreed to loan the Borrower up to an aggregate of $15 million to be disbursed in two tranches (1) one tranche of $10 million (the “Term A Loan”), which was funded on the Closing Date and used to refinance the Original Term Loans, and (2) a second tranche of $5 million which may be disbursed at the Borrower’s sole request prior to March 31, 2019 provided certain conditions are met (the “Term B Loan” and together with the Term A Loan, the “Term Loans”). On July 31, 2019, the Borrower entered into the First Amendment to the Amended and Restated Loan and Security Agreement (the "First Amendment") with the Bank, which amended certain provisions of the Amended and Restated Loan and Security Agreement and the 2018 Success Fee Letter (the "2018 Letter"). In connection with the execution of the First Amendment, the draw period for the Term B Loan was extended to August 15, 2019 and the Company drew down the full $5.0 million Term B Loan on the Settlement Date, bringing the total outstanding debt to $15 million at July 31, 2019. The proceeds of Term Loans were used for general business requirements in accordance with the Amended and Restated Loan and Security Agreement. On December 4, 2020 (the “Closing Date”), the Company closed on the Third Amendment (the “Third Amendment”) of its Amended Loan and Security Agreement with Bridge Bank. Under the terms of the Amendment, the Company repaid the outstanding principal balance of its existing $15 million term loans and simultaneously received a commitment from Bridge Bank to provide a new term loan of $15 million (the “New Term Loan”), if needed.

Under the terms of the Third Amendment, the Company may, at its sole discretion, draw down the New Term Loan at any time over the next twelve months. The New Term Loan, if drawn, shall bear interest at the Index Rate (defined in the Amendment as the greater of 3.25% or the Prime Rate as published by the Wall Street Journal on the last business date of the month the immediately preceding the month in which the interest will accrue) plus 1.25%. In addition, the Company would be required to make payments of interest-only commencing on the first day of the month after the New Term Loan was made until January 2023. The interest-only period may be further extended through July 2023 if the Company maintains compliance certain conditions as outlined in the Amendment. Following the interest-only period, the Company will be required to make equal monthly payments of principal and interest until maturity of the New Term Loan. The maturity date of the New Term Loan is December 1, 2024.

On the Closing Date, the Company was required to pay a non-refundable closing fee of $75,000. As of the Closing Date, the total unamortized loan costs related to the Term Loans amounted to approximately $45,000. These costs were written off on the Closing Date as a charge to interest expense. For the years ended December 31, 2020, 2019, and 2018, the Company recorded interest expense amounting to $76,718, $33,175, and $31,946, respectively related to these costs. In addition, the Amended and Restated Loan and Security Agreement requires the Company to pay a non-refundable final fee equal to 2.5% of the principal amount of each Term Loan funded upon the earlier of the (i) April 1, 2022 maturity date or (ii) termination of the Term Loan via acceleration or prepayment. On the Closing Date, the Company paid a final fee of $375,000. For the years ended December 31, 2020, 2019 and 2018 the Company recorded interest expense of $246,095, $82,031 and $65,104, respectively, related to accrual and payment of the final fee.
