BASIS OF PRESENTATION The interim consolidated financial statements of CytoSorbents Corporation (the “Company”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In the opinion of management, the Company has made all necessary adjustments, which include normal recurring adjustments, for a fair statement of the Company’s consolidated financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission (the “SEC”) on March 9, 2021. The results for the three and six months ended June 30, 2021 and 2020 are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period. Prior to June 30, 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 3. As of June 30, 2021, the Company’s cash balance was approximately $ 65.6 million, which the Company expects will fund the Company’s operations well beyond the next twelve months. As a result, the Company continues to assert 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 the treatment of life-threatening conditions in intensive care and cardiac surgery using blood purification. 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. CytoSorb, the Company’s flagship product, was approved in the European Union (“EU”) in March 2011, and is currently being marketed and distributed 68 countries around the world, as a safe and effective extracorporeal cytokine absorber, designed to reduce the “cytokine storm” or “cytokine release syndrome” 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 EU CE Mark label expansion to include the removal of ticagrelor during cardiopulmonary bypass in patients undergoing cardiothoracic surgery. In May 2020, CytoSorb also received EU CE Mark label expansion to include rivaroxaban removal for the same indication. 7 Table of Contents 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 CytoSorbents’ technology 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 July 2021, the Company received full approval of its Investigative Device Exemption (“IDE”) to conduct he pivotal STAR-T (Safe and Timely Antithrombotic Removal – Ticagrelor) double-blind randomized control trial (“RCT”) in the United States to support FDA marketing approval. If FDA marketing approval for this indication is obtained, the device would be marketed as DrugSorb-ATR in the United States. The DrugSorb-ATR antithrombotic removal system is based on the same polymer technology as CytoSorb. 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 18 issued U.S. patents and multiple international patents, with applications pending both in the U.S. and internationally, including HemoDefend, ContrastSorb, DrugSorb, DrugSorb-ATR 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 2022 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, par value $ 0.001 per share, 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 Dollar, the foreign currency financial statements of the European subsidiary are included in operations. The Euro is the functional currency of the European Subsidiary. Foreign currency transaction gain included in net loss amounted to approximately $ 234,000 and $ 705,000 for the three months ended June 30, 2021 and 2020, respectively. Foreign currency transaction gain (loss) included in net loss amounted to approximately $( 1,071,000 ) and $ 36,000 for the six months ended June 30, 2021 and 2020, respectively. The Company translates assets and liabilities of CytoSorbents Europe GmbH at the exchange rate in effect at the consolidated 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 stockholders’ equity. 8 Table of Contents Cash and Cash Equivalents The Company considers all highly liquid investments 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 its customers’ financial conditions. Management reviews accounts receivable periodically to determine collectability. Balances that are determined to be uncollectible are written off to the allowance for doubtful accounts. The allowance for doubtful accounts contains an accrual for estimated bad debts and amounted to approximately $ 68,000 and $ 47,000 at June 30, 2021 and December 31, 2020, respectively. Inventories Inventories are valued at the lower of cost or net realizable value under the first in, first out (FIFO) method. At June 30, 2021 and December 31, 2020, the Company’s inventory was comprised of finished goods, which amounted to $ 2,303,011 and $ 1,164,635 , respectively; work in process which amounted to $ 1,033,606 and $ 1,222,062 , respectively; and raw materials, which amounted to $ 352,347 and $ 287,102 , 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 consolidated statements of operations and comprehensive loss in the year of disposal. Repairs and maintenance expenditures are expensed as incurred. Patents Legal costs incurred to establish and successfully defend 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. 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 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. 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 in cost of revenue. 9 Table of Contents Research and Development and Clinical Trial Expenses All research and development and clinical trial costs, payments to laboratories and research consultants are expensed when incurred. Advertising Expenses Advertising expenses are charged to selling, general and administrative expenses when incurred. Advertising expenses amounted to approximately $ 148,000 and $ 55,000 for the three months ended June 30, 2021 and 2020, respectively, and approximately $ 302,000 and $ 86,000 for the six months ended June 30, 2021 and 2020, respectively. 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. The Company has provided a valuation allowance against all deferred tax assets. 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 Company follows accounting standards associated with uncertain tax positions. The Company had no unrecognized tax benefits at June 30, 2021 or December 31, 2020. 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 carry forwards to an industrial company. Each of CytoSorbents Europe GmbH, CytoSorbents Switzerland GmbH, CytoSorbents Poland Sp. Z.o.o. and CytoSorbents UK Limited file an annual corporate tax return, 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 U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported periods. 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 government agencies in the United States. (See Note 4 for further information relating to the Company’s revenue.) As of June 30, 2021, no agency, distributor/strategic partner or direct customer accounted for more than 10 % of outstanding grants and accounts receivable. As of December 31, 2020, no agency, distributor/strategic partners or direct customer represented more than 10 % of outstanding grants and accounts receivables. For the three and six months ended June 30, 2021, no agency, distributor/strategic partner accounted for more than 10 %of the Company's total revenue. For the three and six months ended June 30, 2020, no agency, distributor, or direct customer represented more than 10 % of the Company’s total revenue. 10 Table of Contents 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. Net Loss Per Common Share Basic earnings per share is computed by dividing loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share are 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 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 8). 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 other than 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 other shipping and handling costs in cost of revenue. Total freight costs amounted to approximately $ 77,000 and $ 149,000 , respectively, for the three months ended June 30, 2021 and 2020, and $ 140,000 and $ 282,000 , respectively, for the six months ended June 30, 2021 and 2020. ​ 3.

On July 9, 2019, the Company entered into an Open Market Sale Agreement (the “New Sale Agreement”) with Jefferies LLC and B. Riley FBR, Inc. (each an “Agent” and, together, the “Agents”), pursuant to which the Company may sell, from time to time, at its option, shares of the Company’s common stock having an aggregate offering price of up to $ 25 million through the Agents, as the Company’s sales agents. All shares of the Company’s common stock offered and sold, or to be offered and sold under the New Sale Agreement were or will be issued and sold pursuant to the Company’s 2018 Shelf by methods deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, in block transactions or if specified by the Company, in privately negotiated transactions. On April 20, 2020, the Company and the Agents entered into an amendment to the New Sale Agreement (the "Amendment") to provide for an increase in the aggregate offering amount under the New Sales Agreement, such that as of April 20, 2020, the Company may offer and sell Shares having an additional aggregate offering price of up to $ 50 million under the New Sale Agreement, as amended by the Amendment (the "Amended Sale Agreement"). Subject to the terms of the Amended Sales Agreement, the Agents are required to use their commercially reasonable efforts consistent with their normal sales and trading practices to sell the shares of the Company’s common stock from time to time, based upon the Company’s instructions (including any price, time or size limits or other customary parameters or conditions the Company may impose). The Company is required to pay the Agents a commission of up to 3.0 % of the gross proceeds from the sale of the shares of the Company’s common stock sold thereunder, if any. The Company has also agreed to provide the Agents with customary indemnification rights. The offering of the shares of the Company’s common stock under the Amended Sales Agreement will terminate upon the earliest of (a) the sale of the maximum number or amount of the shares of the Company’s stock permitted to be sold under the Amended Sale Agreement and (b) the termination of the Amended Sale Agreement by the parties thereto. During the year ended December 31, 2019, the Company sold 191,244 shares pursuant to the Amended Sale Agreement, at an average selling price of $ 4.11 per share, generating net proceeds of approximately $ 762,000 .

The grant date fair value of these unvested options amounted to approximately $ 7,111,566 . Based upon an assessment by management, which was reviewed with the Board of Directors, as of June 30, 2021, the Company met approximately 12 % of these milestones, and accordingly we have recorded $ 213,347 in stock option expense related to these options in each of the three and six month periods ended June 30, 2021, respectively. 13 Table of Contents Change in Control-Based Awards of Restricted Stock Units: The Board of Directors has granted restricted stock units to members of the Board of Directors, to the Company’s executive officers, and to employees of the Company.

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 with imminent or confirmed respiratory failure 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 to these countries 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). 16 Table of Contents 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. 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 contracts fall into one of the following categories: 1. Fixed price – the Company invoices the contract amount in equal installments over the term of the contract without regard to the timing of the costs incurred related to this contract. If billings on fixed price contracts exceed the costs incurred, revenue will be deferred to the extent of the excess billings. 2. Cost reimbursement – the Company submits monthly invoices during the term of the contract for the amount of direct costs incurred during that month plus an agreed percentage that relates to allowable overhead and general and administrative expenses. Cumulative amounts invoiced may not exceed the maximum amount of funding stipulated in the contract. 3. Cost plus – this type of contract is similar to a cost reimbursement contract but this type also allows for the Company to additionally invoice for a fee amount that is included in the contract. 4. Performance based – the Company submits invoices only upon the achievement of the milestones listed in the contract. The amount to be invoiced for each milestone is documented in the contract. 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: ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 December 31, 2020 Receivables, which are included in grants and accounts receivable ​ $ 3,564,319 ​ $ 2,996,679 Contract liabilities, which are included in accrued expenses and other current liabilities ​ $ 1,682,293 ​ $ 1,014,652 ​ 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 June 30, 2021 and December 31, 2020. ​ 17 Table of Contents 5.

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 during the twelve months following the date of the Third Amendment. 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 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 with 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. 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 . 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). 18 Table of Contents 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.

COMMITMENTS AND CONTINGENCIES Customs Examination In October 2020, the Company received a notice from the German Customs Authorities that they would be conducting an audit of the Company’s import transactions for the years 2018 through 2020 in order to determine if any import taxes would be due. The audit commenced in early December 2020. The primary import activity of the Company is the importation of CytoSorb devices from the United States. The German Customs Authorities are challenging the Harmonized Code that the Company utilizes to import the CytoSorb devices into Germany. The code that has been utilized by the Company has zero import taxes associated with it. The German Customs Authorities have indicated that the Company’s device would be better classified under a different code which has a 1.7 % tax attached to it. As part of the audit process, the Company has provided the German Customs Authorities with extensive information about the CytoSorb device, including data regarding the uses of the device, as well as the instructions for use. In addition, employees of the Company gave the auditors a technical presentation of the scientific properties of the device, focusing on it as an adsorber, as opposed to a filter. The German Customs Authority informed us that the Company must use the code that carries the 1.7% tax. The audit process is on-going and the authorities have indicated it is expected to be completed by approximately September 30, 2021. Based on a thorough review of these facts, during the three months ended March 31, 2021,the Company recorded approximately $ 132,000 of the expense related to 2018, approximately $ 229,000 related to 2019, approximately $ 371,000 related to 2020 and approximately $ 89,000 related to the three months ended March 31, 2021. Commencing in April 2021, the Company began utilizing the code required by the Germany Customs Authority. The Company recorded expense of approximately $ 116,000 related to this tax during the three months ended June 30, 2021. Employment Agreements On July 30, 2019, CytoSorbents Corporation entered into amended and restated executive employment agreements with its principal executives, Dr. Phillip P. Chan, Chief Executive Officer, Vincent Capponi, President and Chief Operating Officer, and Kathleen P. Bloch, Chief Financial Officer. Each of the agreements has an initial term of three years , and was retroactively effective as of January 1, 2019.

LEASES The Company leases its operating facilities in both the United States and Germany under operating lease agreements. In March 2021, CytoSorbents Medical Inc. entered into a lease agreement for a new operating facility at 305 College Road East, Princeton, New Jersey, which contains office, laboratory, manufacturing and warehouse space. The lease commenced on April 1, 2021. The Initial Early Term began on the commencement date (April 1, 2021) and lasts to June 1, 2021. The Early Term commences on June 1, 2021 and lasts until the date of issuance of the certificate of occupancy for the manufacturing space (expected to be September 30, 2021). The lease also contains two five-year renewal options however the Company has determined that it is not likely that they will exercise these options. Commencing on the date of the receipt of the certificate of occupancy (September 30, 2021), the remaining lease term will last for 15.5 years. The lease requires monthly rental payments of $ 25,208 for the Initial Early Term, $ 88,254 for the Early Term and initial monthly payments of approximately $ 111,171 in the first year of the remaining term. Following the first year of the remaining term, the annual base rent will increase by approximately 2.75 % annually over the remaining term. The lease also contains six months of rent abatement (months 1, 2, 3, 25, 26 and 27 of the remaining lease term). In addition to the base rent, payments of operating expenses and real estate taxes will be required. These payments are to be based on actual amounts incurred during 2021 times the Company’s share of the total building space ( 92.3 %). The landlord will also provide an allowance of approximately $ 1,455,000 related to certain building improvements as outlined in the lease. In April 2021, the Company provided the landlord with a letter of credit in the amount of approximately $ 1,334,000 as security. The Company has determined that this lease should be treated as an operating lease in accordance with the provisions of ASC 842. On April 1, 2021, the Company recorded a Right of Use asset and related lease liability of approximately $ 11.6 million, which represents the estimated present value of the lease payments at the commencement date discounted at the Company’s incremental borrowing rate of 9.8 %. In addition, due to the six months of rent abatement and annual base rent escalations during the remaining lease term that is expected to commence on September 30, 2021, the Company will recognize rent expense on this lease on straight line basis over the remaining term of the lease and record a liability for the difference between the rent expense recognized and the required payments under the lease. In April 2021, the Company entered into a Twentieth Amendment to Lease with the landlord at our existing Monmouth Junction facility which became effective May 31, 2021. This amendment extends the term of the lease for the Company’s existing facility to May 31, 2022. The Company’s base rent is approximately $ 35,000 per month. In addition, the Company is obligated to pay monthly operating expenses of approximately $ 30,000 per month. Under the terms of this amendment, the Company will vacate a portion of the space as of May 31, 2022. The Company will continue to lease the remaining space until December 31, 2022, at which time the Company will vacate the remaining space and the lease will terminate. The Company’s base rent for the remaining space will be approximately $ 20,000 per month. Monthly operating expenses will be approximately $ 11,000 per month. In addition, the Company agreed to increase its security deposit by approximately $ 54,000 to a total of $ 150,000 . At the end of the lease term, the entire security deposit will be paid to the landlord for the purpose of making any needed repairs to the vacated premises, and the Company will have no further obligation to pay for repairs to the vacated premises. Effective April 1, 2021, the Company adjusted its incremental borrowing rate to the incremental borrowing rate used in the College Road lease and recalculated the right of use asset and lease liability under the amended terms of this lease. In addition, the Company also adjusted the incremental borrowing rate and related right of use asset and lease liability on the existing Germany office lease effective April 1, 2021. In Germany, the Company leases its operating facility under two operating lease agreements. These leases require combined base rent payments amounting to approximately $ 9,000 per month. The initial lease term of both leases ends August 31, 2021. In addition, the Company is obligated to monthly operating expenses of approximately $ 2,900 per month. Both leases have a five year option to renew that would extend the lease term to August 31, 2026. There are no provisions in the leases to increase the base rent during the renewal period. There were no lease incentives and no initial direct costs were incurred related to these leases. In January 2021, CytoSorbents Europe GmbH entered into a lease for 1,068 square meters of additional warehouse space. The lease commenced on April 1, 2021 and requires monthly payments of base rent of $ 7,784 and other costs of approximately $ 239 and has a term of five years . The lease also has an option to extend the lease term for an additional five-year period through March 31, 2031. The Company has determined that this lease should be treated as an operating lease in accordance with the provisions of ASC 842. On April 1, 2020, the Company recorded a Right of Use asset and related lease liability at the estimated present value of the lease payments at the commencement date of approximately $ 594,000 . 21 Table of Contents Right-Of-Use Asset and Lease Liability: The Company's consolidated balance sheets reflect the value of the right-of-use asset and related lease liability. This value was calculated based on the present value of the remaining base rent lease payments. The remaining lease payments include the renewal periods for both facilities as the Company has determined that it is probable that the renewal options will be exercised under each of the lease agreements. The discount rate used was the Company’s incremental borrowing rate, which is 9.8 %, as the Company could not determine the rate implicit in the lease. As a result, the value of the right-of- use asset and related lease liability is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2021 2020 Right-of-use asset $ 13,263,531 $ 1,029,123 ​ ​ ​ ​ ​ ​ ​ Total lease liability ​ $ 13,263,531 ​ $ 1,029,123 Less current portion ​ ( 251,524 ) ​ ( 447,485 ) Lease liability, net of current portion ​ $ 13,012,007 ​ $ 581,638 ​ The maturities of the lease liabilities are as follows during the year ended June 30: ​ ​ ​ ​ ​ 2022 ​ $ 1,544,749 2023 ​ 1,684,519 2024 ​ 1,251,455 2025 ​ 1,642,126 2026 ​ 1,681,657 Thereafter ​ 19,150,802 Total lease payments ​ ​ 26,955,308 Present value discount ​ ​ ( 13,691,777 ) Total ​ $ 13,263,531 ​ For the three months ended June 30, 2021 and 2020, operating cash flows paid in connection with operating leases amounted to approximately $ 430,000 and $ 213,000 , and $ 661,000 and $ 447,000 for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021 and December 31, 2020, the weighted average remaining lease term was 14.2 years and 4.0 years, respectively. 8. NET LOSS PER SHARE Basic loss per share and diluted loss per share for the three months ended June 30, 2021 and 2020 have been computed by dividing the net loss for each respective period by the weighted average number of shares outstanding during that period. All outstanding options and restricted stock awards representing approximately 9,905,000 and 7,828,000 incremental shares at June 30, 2021 and 2020, respectively, have been excluded from the computation of diluted loss per share as they are anti-dilutive. ​ 9. SUBSEQUENT EVENT On July 14, 2021, the Company filed a registration statement on Form S-3 with the SEC, which was amended on July 20, 2021 (as amended, the “2021 Shelf”).
