CytoSorbents Corporation Nasdaq: CTSO Q2 2026 Earnings Conference Call August 6, 2026
Statements in this presentation include forward - looking statements intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995 . These forward - looking statements include, but are not limited to, statements about our plans, objectives, future targets and outlooks for our business, representations and contentions, and the outcome of our regulatory submissions, and are not historical facts and typically are identified by use of terms such as “may,” “should,” “could,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “continue” and similar words, although some forward - looking statements are expressed differently . You should be aware that the forward - looking statements in this presentation represent management’s current judgment and expectations, but our actual results, events and performance could differ materially from those in the forward - looking statements . Factors which could cause or contribute to such differences include, but are not limited to, our restructuring of our direct sales team and strategy in Germany, the impact of geopolitical events including the recent war in Iran, our ability to successfully obtain U . S . FDA and Health Canada regulatory approval and marketing authorization, our ability to complete our strategic workforce and cost reduction plan to reduce costs, optimize operations, and achieve operating cash - flow break - even in the second half of 2026 , our ability to appropriately finance the Company, including our ability to meet our financial obligations and comply with the covenants under our existing debt agreement, our ability to fund and develop new and existing research and development programs, and the risks discussed in our Annual Report on Form 10 - K, filed with the SEC on March 30 , 2026 , as updated by the risks reported in our Quarterly Reports on Form 10 - Q, and in the press releases and other communications to shareholders issued by us from time to time which attempt to advise interested parties of the risks and factors which may affect our business . We caution you not to place undue reliance upon any such forward - looking statements . We undertake no obligation to publicly update or revise any forward - looking statements, whether as a result of new information, future events, or otherwise, other than as required under the Federal securities laws . Safe Harbor Statement 2 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, the gain or loss of foreign exchange translation, and restructuring charges . 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, the gain or loss of foreign exchange translation, and restructuring charges from Net Loss and Net Loss Per Share, respectively . Additionally, we use the non - GAAP financial measure of Negative Free Cash Flow which consists of net cash used in operating activities plus net cash used in investing activities . 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 .

Value Driver #3: Opening the U.S. Market Through DrugSorb - ATR Dr. Efthymios “Makis” Deliargyris, MD, FACC, FESC, FSCAI Chief Medical Officer 15 DrugSorb - ATR is an investigational device in th e U.S. and Canada and not yet cleared/approved
| 16 Blood Thinners and Cardiac Surgery • Tens of millions of patients globally take Direct Oral Anticoagulants ( e.g , DOACs like Eliquis ® and Xarelto ® ) and antiplatelet agents ( e.g , Brilinta ® ) either chronically or acutely to reduce risk of heart attack, stroke, and other serious thrombotic complications • Each year, an estimated 10% will require emergent or urgent surgery, including cardiac surgery • ~5 - 10% of emergency cardiac surgeries involve patients on chronic DOAC therapy • ~5 - 10% of heart attack patients on antiplatelet agents are not eligible for a stent and require CABG surgery • Blood thinners significantly increase the risk of perioperative bleeding in cardiac surgery. Delay of surgery for multiple days for drug clearance is typically recommended to reduce this risk • There is a major unmet need in patients awaiting urgent cardiothoracic surgery • Many patients cannot wait due to the need for emergency surgery • Waiting for drug washout may increase the risk of poor patient outcomes (e.g. thrombotic events, clinical instability, and sudden death) and wastes valuable hospital resources • DrugSorb - ATR has received two FDA Breakthrough Designations, highlighting the lack of available effective therapies for this problem. We believe DrugSorb - ATR has the potential to address this pervasive and serious unmet medical need DrugSorb - ATR is an investigational medical device in the U.S. and Canada and is not yet cleared or approved. Brilinta ® , Eliquis ® , and Xarelto ® are trademarks of AstraZeneca, Bristol - Myers Squibb, and Bayer, respectively

24 - hr Chest Tube Drainage after CABG: Cumulative & Quartile Analysis CTD = Chest Tube Drainage For context, the average total blood volume of a 165 pound person is approximately 4,000 - 5,000 mL of blood. So, >945 mL is equivalent to approximately 20 - 25% of a patient’s total blood volume 22 DrugSorb - ATR is an investigational device in th e U.S. and Canada and not yet cleared/approved
• 58% risk reduction for major bleeding • 16.3% absolute reduction (13.7% treatment vs 30.0% control, p= 0.041) translates to NNT of 6 • Means that 1 major bleed is prevented for every 6 patients treated Significant Reduction in Major Bleeding Equates to NNT = 6 UDPB = Universal Definition of Perioperative Bleeding; CTD = Chest Tube Drainage; NNT = Number Needed to Treat 23 DrugSorb - ATR is an investigational device in th e U.S. and Canada and not yet cleared/approved

| 25 FDA Regulatory Path for DrugSorb - ATR and Brilinta ® • Because the primary endpoint of STAR - T was missed, FDA denied our De Novo 510(k) application (approval standard requires that “probable benefit” outweighs “probable risk”) and subsequently upheld that denial in appeal • However, there were three important positive outcomes of the appeal decision: • FDA stated no major issues with safety – key to the benefit - to - risk evaluation for De Novo devices • FDA stated new clinical trial in NOT needed - additional information may support Company’s desired label claim • FDA indicated that a focused review of a new De Novo submission on the remaining open items was possible • During follow - up discussions with FDA, we obtained clarity on the additional information to support “probable benefit: • Additional mechanistic data that will likely be generated from a small experimental study, and • RWE from existing data from the increasing use of the device in the everyday practice in Europe • We will discuss options for the additional mechanistic data with FDA during a pre - sub meeting later this month • We have identified appropriate data sources for the RWE analyses – preliminary results at ESC • Once the additional information is available, we will file the new De Novo application DrugSorb - ATR is an investigational device in th e U.S. and Canada and not yet cleared/approved
| 26 Potential Second Shot on Goal: DOAC Removal • Tens of millions of patients are on Direct Oral Anticoagulants (DOAC) for atrial fibrillation, VTE, etc. Eliquis ® is the #7 pharmaceutical in the world ($14B global 2025 sales); Xarelto ® ($5B global 2025 sales) are the market leaders • DrugSorb - ATR has received a second FDA Breakthrough Device Designation for the removal of Eliquis ® and Xarelto ® during cardiac surgery • We have previously discussed our intention to pursue an expanded label for DrugSorb - ATR to include removal of DOACs in cardiac surgery following an initial marketing approval • Given delays in the ticagrelor submission, we have now scheduled a separate pre - submission meeting with FDA also later this month to review data currently available for the DOAC indication and determine what, if any, additional information may be required to support a parallel De Novo submission for DOAC removal Eliquis ® and Xarelto ® are trademarks of Bristol - Myers Squibb and Bayer, respectively DrugSorb - ATR is an investigational device in th e U.S. and Canada and not yet cleared/approved
| 27 Meanwhile, Evidence Base for ATR Continues to Grow • At EuroPCR 2026 (Paris; May 19 - 22) , the world - leading course in interventional cardiovascular medicine, two key presentations were made on antithrombotic removal: • Urgent CABG in ACS: Impact of P2Y12 Choice and Intraoperative Hemoadsorption on Perioperative Bleeding - PSM Analysis of Real - World Data • Intraoperative DOAC Removal During CABG: An Interim Report From the STAR registry • Later this month in Munich at ESC 2026 (Aug 28 - 31) , the world’s largest CV conference, two additional analyses on antithrombotic removal in cardiac surgery will be presented: • Intraoperative ticagrelor removal to reduce bleeding after urgent CABG: Matched comparison of patient level observational data • Intraoperative antithrombotic removal during urgent CABG: Early German experience with a novel hemoadsorption device • These rigorous RWE analyses highlight the increasing adoption of our technology as part of the operative protocols.at leading European heart centers and the bleeding reductions with the use of our device DrugSorb - ATR is an investigational device in th e U.S. and Canada and not yet cleared/approved

Dr. Phillip Chan, MD, PhD Chief Executive Officer Value Driver #4: Unlocking the Strategic Value of HemoDefend - BGA | 29
The Importance of Universal Plasma • Plasma is the life - saving acellular portion of blood that contains coagulation factors, antibodies, etc. that are vital for blood clotting, immunity, and other functions - used widely in trauma and critical care, but is blood - type specific due to the present of anti - A and anti - B blood group antibodies (BGA) • Universal Plasma can be given to anyone regardless of blood type and is generated artificially by removing the anti - A and anti - B antibodies, making it readily available, but the technology is expensive and difficult to scale • The wide availability of Universal Plasma would: • Significantly simplify the logistics of plasma collection and usage at the hospital level • Dramatically lower complexity of plasma administration in mass casualty and emergency situations without blood - typing the patient (e.g., first responders, medics, paramedics, emergency room, mass trauma, rad nuc ) • When coupled with freeze - dried plasma technology, it would enable the “ Holy Grail” of lightweight, portable, non - refrigerated (no cold chain) freeze - dried universal plasma which enables the product to be stockpiled and have broad availability on ambulances, first responder vehicles, medic packs, etc. • In addition, the ability to remove anti - A and anti - B antibodies is important in the multi - billion dollar plasma processing industry (e.g., Grifols, CSL Plasma, Takeda, Baxter, others) who make IVIG, albumin, clotting factors, etc • HemoDefend - BGA can remove anti - A and anti - B antibodies to easily and cost - effectively create Universal Plasma and other blood products | 30 HemoDefend - BGA is an investigational device in the U.S. and not yet cleared/approved
HemoDefend - BGA: Enabling Universal Plasma and Blood Products • Simple, gravity - driven filter that removes anti - A and anti - B blood group antibodies (BGA) to enable universal blood products • Same filter for plasma, platelets, and whole blood • Addresses critical needs in trauma, emergency, military, and civilian transfusion as well as in the plasma processing industry • Developed with $16M+ in non - dilutive DoD/government funding and supported by leading experts and partners • De - risked product concept with path to U.S. FDA and EU clearance and potential additional non - dilutive funding from DoD or government agencies • Scalable platform technology, targeting a multi - billion dollar market opportunity • Exit via acquisition by plasma, trauma, or blood tech leaders • Pre - commercial and non - revenue generating today; Not part of CytoSorbents’ core operating or cash - producing business While strategically important, HemoDefend is not generating revenue, non - core to the business, and not reflected in CytoSorbents’ current valuation | 31
Universal Plasma Ready • Fast — Universal plasma under 15 minutes • Safe — Preserves clotting factors, biocompatible • Simple — No power, no training, closed sterile system • Ready — Shelf life >1 year, scalable manufacturing Universal Plasma in 15 Minutes — No Equipment Needed Collect Plasma Filter with HemoDefend - BGA • Plasma flows by gravity through a small filter • Beads inside remove antibodies • Safe, universal plasma collected in a new bag | 32
HemoDefend - BGA: Unlocking Value Current Status: • HemoDefend - BGA development is completed and has been tested and validated by multiple blood centers and government and industry players. Currently undergoing device validation for human clinical studies • In July 2026, received constructive FDA feedback regarding an anticipated clinical pathway following a pre - IDE submission to FDA, with plans to begin clinical trial testing • In continued discussions with U.S. government agencies regarding potential non - dilutive funding of clinical trials through approval • Universal Fresh Frozen Plasma could greatly simplify blood logistics in hospitals – a multi - billion dollar market • First freeze - dried plasma BLA has been granted, paving the way to the holy grail of “Freeze - dried Universal Plasma” – plasma that can be on any emergency room shelf or first responder vehicle or military vehicle to treat trauma and severe hemorrhage. HemoDefend - BGA is a valuable asset with multiple potential pathways to create shareholder value, including commercial partnerships, licensing opportunities, government funding, and other strategic alternatives | 33
