CytoSorbents Reports First Quarter 2026 Financial Results, Recent Business Highlights, and Regulatory Update

PRINCETON, N.J., May 13, 2026 /PRNewswire/ -- CytoSorbents Corporation (NASDAQ:CTSO), a leader in the treatment of life-threatening conditions in the intensive care unit and cardiac surgery using blood purification, today reported financial results for the first quarter ended March 31, 2026, recent business highlights, and provides a regulatory update. 

First Quarter 2026 Financial Results

• Revenue was $8.9 million, an increase of 2% over the prior year, from $8.7 million
• Gross margin was 69% in the quarter compared to 71% in Q1 2025
• Operating loss was $3.0 million, compared to $3.9 million in Q1 2025  
• Net loss was $5.1 million or $0.08 per share, compared to a net loss of $1.5 million or $0.02 per share in Q1 2025.  The increase was due primarily to the non-cash impact of changes in foreign currency transactions year-over-year  
• Adjusted net loss, which excludes the impact of non-cash changes in foreign currency transactions and non-cash stock compensation, was $3.4 million or $0.05 per share, compared to an adjusted net loss of $3.7 million or $0.06 per share in Q1 2025
• Adjusted EBITDA loss, which also excludes the impact of non-cash changes in foreign currency transactions and non-cash stock compensation was $2.2 million compared to a loss of $2.7 million in Q1 2025
• Total cash, cash equivalents, and restricted cash was approximately $6.4 million, compared to $7.8 million as of December 31, 2025  
• Total cash burn in the quarter, excluding $0.3 million in restructuring-related payments, was approximately $1.1 million  

"First quarter sales were $8.9 million, driven by 13% growth in our direct sales territories outside of Germany," stated Dr. Phillip Chan, Chief Executive Officer of CytoSorbents Corporation.  "Our Germany sales team also performed well, achieving sales slightly below last year, but with a smaller and more focused team – reflecting new leadership, sales execution, account targeting, productivity, and customer engagement.  Given the importance of the German market, we plan to selectively expand our commercial team to improve account coverage and drive growth opportunities in both critical care and cardiac surgery.

Distributor sales were flat year-over-year, as progress across several territories was offset by delayed distributor orders of approximately $500,000 in parts of the Middle East and neighboring regions due to geopolitical and economic instability related to the U.S.-Iran war.  This unexpected disruption has slowed the anticipated growth of our recently established subsidiary in Dubai, UAE, although we expect conditions to improve as the conflict stabilizes.

Gross margin declined marginally to 69% in the first quarter, primarily due to intentionally reduced production volumes aimed at lowering inventory levels and improving working capital.  

In the fourth quarter of 2025, we implemented a strategic workforce and cost reduction initiative, reducing headcount by approximately 10% while lowering operating and production expenses.  The initial benefits of this program were reflected in lower expenses and improved operating margins in the first quarter.  Meanwhile, we have continued to make operational improvements and cost reductions and believe these actions will continue to drive improvements in the coming quarters to support our goal of achieving operating cash flow breakeven in the second half of this year."  

DrugSorb-ATR® for Brilinta®

"In August 2025, we received the FDA's decision on our appeal of the original DrugSorb-ATR application.  Importantly, the Agency identified no concerns regarding device safety but upheld the prior denial of the application and requested additional information to support the proposed indication for reducing the severity of perioperative bleeding in patients undergoing CABG surgery while on Brilinta® (ticagrelor, AstraZeneca).

Following the appeal decision and based on feedback from FDA, we announced our intention to submit a new De Novo application incorporating additional supporting information, primarily based on real-world evidence and clinical outcomes generated through routine clinical use of the device.  As part of this process, we held a formal pre-submission meeting with the FDA in late January 2026 and have continued to engage with the Agency to clarify the requirements for the new De Novo submission, including whether all information would be required within the submission or as a post-marketing requirement. Based on these interactions, the FDA has requested additional mechanistic data to be included alongside the real-world evidence within the new De Novo submission.

We are currently evaluating options to generate the additional mechanistic data on an expedited basis and expect to schedule an additional pre-submission meeting with the FDA, if needed, to discuss and align on the proposed approach.  Once alignment is achieved, we anticipate completing the required work and submitting a new De Novo application in late 2026 or early 2027.  Though delayed from our timeline, we now have clearer direction and are committed to obtaining the new information and filing a new De Novo submission as soon as possible.  Following submission, a regulatory decision would generally be expected within the FDA's targeted 150-day MDUFA review timeline, although the actual review period may be shorter or longer depending on the nature and extent of interactive review questions from the Agency.

Meanwhile, the U.S. and Canadian pivotal STAR-T randomized, controlled trial results are now available in PDF form from the Journal of Thoracic and Cardiovascular Surgery (2026) - the leading peer-reviewed cardiothoracic surgery journal in the U.S., highlighting "Intraoperative use of DrugSorb-ATR is safe in patients operated within 2 days of ticagrelor discontinuation [with] significant reductions in severe bleeding events in the prespecified CABG subpopulation"

DrugSorb-ATR for DOACs: Eliquis® and Xarelto®

"We have previously discussed our intention, following anticipated FDA marketing approval of DrugSorb-ATR for Brilinta®, to pursue an expanded indication for the removal of direct oral anticoagulants (DOACs), such as Eliquis® (apixaban, Pfizer/BMS) and Xarelto® (rivaroxaban, Bayer/Janssen).  At the same time, we continue to observe increasing real-world adoption, clinical use, and published evidence supporting the use of our technology for DOAC removal in cardiac surgery, reinforcing the significant unmet medical need globally. 

Within the next 30 days, we plan to submit a separate pre-submission request to the Agency to review the data currently available for the DOAC indication that include drug removal data from benchtop testing and data from real-world use and to determine what, if any, additional information may be required to support a parallel De Novo submission for DOAC removal. 

Having this potential second shot on goal is aligned with our other FDA Breakthrough Device Designation for DrugSorb-ATR, to remove DOACs during cardiac surgery.  Globally, tens of millions of patients are on chronic or life-long DOAC therapy due to atrial fibrillation, deep vein thrombosis, pulmonary embolism, peripheral vascular disease, or post-surgical prophylaxis.  An estimated 5-10% of emergent cardiac surgery cases involve patients who are currently therapeutic on a DOAC and risk serious or life-threatening perioperative bleeding. 

In 2025, Eliquis ranked #7 among the top-selling pharmaceuticals globally, generating approximately $14.4 billion in worldwide sales and accounting for a majority share of new oral anticoagulant prescriptions.  Xarelto generated approximately $5.1 billion in global sales. We estimate that the combined U.S. total addressable market for DrugSorb-ATR in cardiac surgery across Brilinta® and the DOACs is between $500 million and $1 billion annually."

New Health Economic Analysis in Septic Shock

"Finally, in our last earnings call update, we highlighted many key publications across critical care and cardiac surgery.  Recently, an important study entitled 'Impact of CytoSorb Hemoadsorption Therapy on Cost-Effectiveness and Length of Stay in Critical Care Patients: A Preliminary Study from a Swiss High-Volume Center", was published in the peer-reviewed journal Healthcare.  This study provides compelling real-world evidence for the cost-effectiveness of CytoSorb hemoadsorption in a comparative analysis of 246 ICU patients with septic shock.  Compared to patients treated with standard of care alone, those additionally treated with CytoSorb showed significant reductions in ICU and hospital length of stay, duration of mechanical ventilation among survivors, and nursing workload, while total hospital treatment costs were not significantly increased.  CytoSorb therapy showed a clear advantage in net case profitability (revenue minus costs), with significantly higher earnings per case compared to standard of care.  These results highlight the cost-effectiveness of CytoSorb therapy and the ability to achieve clinical, operational, and economic benefits in a resource-intensive critical care setting."

Dr. Chan concluded, "While we continue to navigate what we believe to be temporary headwinds in the Middle East, we remain focused on executing on our key priorities including:  strengthening commercial performance, reducing operating expenses, and progressing toward our goal of achieving operating cash flow breakeven in the second half of this year.  At the same time, we are advancing the substantial long-term U.S. opportunity for DrugSorb-ATR.  We now have clearer regulatory direction from the FDA for our ticagrelor application and are actively evaluating a potential parallel path focused on DOACs that could significantly expand the U.S. market opportunity.  We believe the actions we are taking today are building a stronger, more resilient company and positioning us to deliver meaningful long-term value for patients, clinicians, and shareholders."

About DrugSorb-ATR

In the U.S. and Canada, CytoSorbents is developing the DrugSorb™-ATR antithrombotic removal system, an investigational device based on an equivalent polymer technology to CytoSorb, to reduce the severity of perioperative bleeding in high-risk surgery due to blood thinning drugs. It has received two U.S. Food and Drug Administration ("FDA") Breakthrough Device Designations: one for the removal of ticagrelor and another for the removal of the direct oral anticoagulants (DOAC) apixaban and rivaroxaban in a cardiopulmonary bypass circuit during urgent cardiothoracic procedures.

The Company continues to actively pursue regulatory approval of DrugSorb-ATR with the FDA and expects to pursue regulatory approval in Canada with better visibility from the FDA. DrugSorb-ATR is not yet granted or approved in the United States and Canada, respectively.

About Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements, we use the non-GAAP financial measures of EBITDA, which measures earnings before interest, income taxes, depreciation and amortization, and Adjusted EBITDA which further excludes non-cash stock compensation expense, and gain or loss of foreign exchange translation. We also use the non-GAAP financial measures of Adjusted Net Income or Loss and Adjusted Net Income or Loss Per Share which excludes non-cash stock compensation expense and gain or loss of foreign exchange translation from Net Loss and Net Loss Per Share, respectively. These non-GAAP measures are not based on any comprehensive set of accounting rules or principles and should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures should be read in conjunction with our financial statements prepared in accordance with GAAP. The reconciliations of the non-GAAP measures to the most directly comparable financial measures calculated and presented in accordance with GAAP should be carefully evaluated. We use these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance and that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, and analyzing future periods. We believe these non-GAAP financial measures are useful to investors because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (2) they are used by investors and the analyst community to help them analyze the performance of our business, the Company's cash available for operations, and the Company's ability to meet future capital expenditure and working capital requirements.  For a reconciliation of non-GAAP financial measures to the most comparable GAAP measure, see the reconciliation included in the financial tables.  All non-GAAP adjustments are presented pre-tax.

About CytoSorbents Corporation (NASDAQ:CTSO)

CytoSorbents Corporation is a leader in the treatment of life-threatening conditions in the intensive care unit and cardiac surgery through blood purification. CytoSorbents' proprietary blood purification technologies are based on biocompatible, highly porous polymer beads that can actively remove toxic substances from blood and other bodily fluids by pore capture and surface adsorption. Cartridges filled with these beads can be used with standard blood pumps already in the hospital (e.g. dialysis, continuous renal replacement therapy or CRRT, extracorporeal membrane oxygenation or ECMO, and heart-lung machines), where blood is repeatedly recirculated outside the body, through our cartridges where toxic substances are removed, and then back into the body. CytoSorbents' technologies are used in a number of broad applications. Specifically, two important applications are 1) the removal of blood thinners during and after cardiothoracic surgery to reduce the risk of severe bleeding, and 2) the removal of inflammatory agents and toxins in common critical illnesses that can lead to massive inflammation, organ failure and patient death. The breadth of these critical illnesses includes, for example, sepsis, burn injury, trauma, lung injury, liver failure, cytokine release syndrome, and pancreatitis as well as the removal of liver toxins that accumulate in acute liver dysfunction or failure, and the removal of myoglobin in severe rhabdomyolysis that can otherwise lead to renal failure. In these diseases, the risk of death can be extremely high, and there are few, if any, effective treatments.

CytoSorbents' lead product, CytoSorb^®, is approved in the European Union and distributed in over 70 countries worldwide, with more than 300,000 devices used cumulatively to date.  CytoSorb was originally launched in the European Union under CE mark as the first cytokine adsorber.  Additional CE mark extensions were granted for bilirubin and myoglobin removal in clinical conditions such as liver disease and trauma, respectively, and for ticagrelor and rivaroxaban removal in cardiothoracic surgery procedures. CytoSorb has also received FDA Emergency Use Authorization in the United States for use in adult critically ill COVID-19 patients with impending or confirmed respiratory failure.  CytoSorb is not yet approved or cleared in the United States.

In the U.S. and Canada, CytoSorbents is developing the DrugSorb™-ATR antithrombotic removal system, an investigational device based on an equivalent polymer technology to CytoSorb, to reduce the severity of perioperative bleeding in high-risk surgery due to blood thinning drugs.  It has received two FDA Breakthrough Device Designations:  one for the removal of ticagrelor and another for the removal of the direct oral anticoagulants (DOAC) apixaban and rivaroxaban in a cardiopulmonary bypass circuit during urgent cardiothoracic surgery.  The Company is actively pursuing regulatory approval of DrugSorb-ATR with the U.S. FDA and will pursue regulatory approval with Health Canada with better visibility from the FDA.  DrugSorb-ATR is not yet granted or approved in either the U.S. or Canada.

The Company has numerous marketed products and products under development based upon this unique blood purification technology protected by many issued U.S. and international patents and registered trademarks, and multiple patent applications pending, including ECOS-300CY®, CytoSorb-XL™, HemoDefend-RBC™, HemoDefend-BGA™, VetResQ®, K+ontrol™, DrugSorb™, ContrastSorb, PuriFi®, HotSwap®, and others.
