NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

March 31, 2024

1. 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 presentation 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, 2023, included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission (the “SEC”) on March 14, 2024. The results for the three months ended March 31, 2024 and 2023, are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period.

As of March 31, 2024, the Company’s cash, cash equivalents and restricted cash balances were approximately $10.1 million, including approximately $8.6 million in cash and cash equivalents and approximately $1.5 million in restricted cash, which is not expected to fund the Company’s operations beyond the next twelve months from the issuance of these consolidated financial statements. This matter raises substantial doubt about the Company’s ability to continue as a going concern. As a result, the accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company is actively pursuing financing sources, including less or non-dilutive debt financing, royalty financing, strategic or direct investments, equity financing, and/or combinations thereof. There can be no assurance that management will be successful in these endeavors.

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 the Company’s clinical trial activities in the United Kingdom. In March 2022, the Company formed CytoSorbents Medical UK Limited to provide marketing and direct sales services in the United Kingdom and the Republic of Ireland, a wholly-owned subsidiary of CytoSorbents Europe, GmbH. In October 2022, the Company formed CytoSorbents France SAS, a wholly-owned subsidiary of CytoSorbents Europe, GmbH, to provide marketing and direct sales services in France. In May 2023, the Company formed CytoSorbents India Private Limited to provide marketing and direct sales services in India. CytoSorb, the Company’s flagship product, was approved in the European Union (“EU”) in March 2011 and is currently being marketed and distributed in more than 75 countries around the world, as an effective extracorporeal cytokine absorber, designed to reduce the “cytokine storm” or “cytokine release syndrome” seen in critical illnesses that may result in massive inflammation, organ failure, and patient death. 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 that 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.

Table of Contents

In April 2020, CytoSorb received United States Food and Drug Administration (“FDA”) Emergency Use Authorization (“EUA”) of CytoSorb for use in adult critically ill COVID-19 patients with imminent or confirmed respiratory 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 for its DrugSorb-ATR Antithrombotic Removal System 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 the pivotal STAR-T (Safe and Timely Antithrombotic Removal – Ticagrelor) double-blind randomized control trial (“RCT”) for up to 120 patients in the United States to support FDA marketing approval. In July 2023, the Company announced that enrollment in the STAR-T trial has completed, and in August 2023, the Company announced completion of the STAR-T trial, following the last scheduled patient follow-up. In December 2023, the Company announced that the independent Data Safety Monitoring Board (the “DSMB”) performed a final review of the full unblinded data on all 140 patients in the STAR-T trial and concluded there were no issues with device safety, meeting the primary safety endpoint of the study. The Company has also performed the initial data analysis on the primary effectiveness endpoint of STAR-T trial. Based on this analysis, the study did not meet the primary effectiveness endpoint in the overall patient population that underwent different types of cardiac surgeries. However, the study did demonstrate evidence of reduced bleeding complications, including serious bleeding events, in patients in the pre-specified isolated coronary artery bypass graft (“CABG”) surgery population, representing more than 90% of the overall study population. The topline results of 140-patient, double-blinded, multicenter, pivotal STAR-T randomized, controlled trial were featured as a late breaking presentation at the 104^th Annual Meeting of the American Association for Thoracic Surgery (AATS) held in Toronto, Canada on April 28, 2024. The Company believes the safety and effectiveness data from STAR-T will support the parallel regulatory submission of DrugSorb-ATR to the FDA and Health Canada in the third quarter of 2024.

In August 2021, the Company announced that it was granted a second Breakthrough Device designation for its DrugSorb-ATR Antithrombotic Removal System by the FDA. This Breakthrough Device designation covers the removal of the Direct Oral Anticoagulants (DOACs) apixaban and rivaroxaban in a cardiopulmonary bypass circuit to reduce the likelihood of serious perioperative bleeding during urgent cardiothoracic surgery. In October 2021, the Company also received full FDA approval of an IDE application to conduct a double-blind, randomized, controlled clinical study for up to 120 patients entitled, “Safe and Timely Antithrombotic Removal – Direct Oral Anticoagulants (STAR-D),” in the United States to support FDA marketing approval. The study has been postponed while the Company concentrates its clinical focus on STAR-T.

If FDA marketing approval is obtained for either the removal of ticagrelor or direct oral anticoagulants indications, the device will be marketed as DrugSorb-ATR in the United States. The DrugSorb-ATR Antithrombotic Removal System is based on the same polymer technology as CytoSorb.

In May 2022, the Company announced that the Company entered into a three-year preferred supplier agreement with Asklepios, making CytoSorb available without restrictions to all of the approximately 170 healthcare facilities across 14 states throughout Germany at which Asklepios operates. This includes Asklepios Klinik St. Georg in Hamburg, Germany, which pioneered the use of CytoSorb to remove antithrombotic drugs during cardiothoracic surgery and is well-known for their seminal publication on CytoSorb use for this application during emergency cardiac surgery in patients at high risk of bleeding.

In June 2022, the Company announced that, following a successful pilot program in three countries, the Company signed an expanded non-exclusive agreement with Nikkiso Europe GmbH (“Nikkiso”) to distribute Nikkiso’s PureADJUST stand-alone hemoperfusion pump and accessories in a total of 14 countries. In addition to securing the rights to sell Nikkiso’s stand-alone pump and accessories in Germany, Austria, and Luxembourg, the Company entered into an expanded multi-country reseller agreement with Nikkiso covering the following countries: Belgium, Bosnia and Herzegovina, Croatia, Finland, France, Iceland, Lichtenstein, Poland, Serbia, Slovenia and Switzerland. The Company will also be able to provide field support services in these countries. In September 2023, the distribution agreement with Nikkiso expired, and the Company indicated that it would not seek renewal of the agreement. The Company is actively working with a new supplier to provide a stand-alone hemoperfusion pump.

Table of Contents

In August 2022, the Company entered into a Marketing Agreement (the “Marketing Agreement”) with Fresenius Medical Care Deutschland GmbH (“Fresenius”), which expands the Company’s strategic partnership with Fresenius by establishing a multi-stage global collaboration to combat life-threatening diseases in critical care. The Marketing Agreement provides for the combined marketing and promotion of CytoSorb with Fresenius’ critical care products by Fresenius’ marketing organization worldwide, excluding the United States. The Marketing Agreement has an initial term of three years, with an automatic renewal for an additional two years at the end of such initial term, subject to earlier termination by either of the parties (the “Term”). Compared to the prior co-marketing agreement between the parties, the Marketing Agreement intends to increase the commitments from both parties and to ensure an ongoing and consistent level of marketing and promotional activity specifically focused around CytoSorb, where Fresenius will actively market and promote CytoSorb as the featured blood purification therapy for removal of cytokines, bilirubin, and myoglobin on its critical care platforms. Specifically, the Marketing Agreement provides that various Fresenius-led in-person, virtual, social media, and web-based marketing programs and events will feature the CytoSorb therapy and highlight the cooperation between the two companies in the field of critical care during the Term. To help support the increased marketing and promotional efforts of the expanded collaboration, CytoSorbents has agreed to subsidize a portion of the marketing costs through a royalty payment to Fresenius Medical Care based on CytoSorb sales in the intensive care unit on Fresenius Medical Care platforms, excluding the United States. In addition to strengthening and expanding the global marketing of CytoSorb, the Company and Fresenius also plan to work together to bring new innovative solutions to the market. The Marketing Agreement also includes the certification of compatibility of CytoSorb for usage on Fresenius’ current critical care platforms. The launch of this program is expected to occur in 2024.

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, as of December 31, 2023, is protected by 21 issued U.S. patents and multiple international patents, with applications pending both in the U.S. and internationally. These patents and patent applications are directed to various compositions and methods of use related to the Company’s blood purification technologies and are expected to expire between 2024 and 2038, absent any patent term extensions. Management believes that any near-term expiring patents will not have a significant impact on the Company’s 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

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. The Euro is the functional currency of the European Subsidiary. Foreign currency transaction gain (loss) included in net loss amounted to approximately $(1,426,000) and $661,000 for the three months ended March 31, 2024 and 2023, respectively. The Company translates assets and liabilities of all of its foreign subsidiaries 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.

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.

Table of Contents

The following table provides a summary of cash and cash equivalents and restricted cash to amounts shown in the consolidated balance sheets:


	March 31, 2024		December 31, 2023
Cash and cash equivalents	$	8,608,380	$	14,131,137
Restricted cash		1,483,958		1,483,958
Total cash, cash equivalents and restricted cash	$	10,092,338	$	15,615,095

Restricted Cash

The Company’s total restricted cash in the amount of $1,483,958 consists of cash of $1,467,459 that the Company is obligated to maintain as collateral for the outstanding letter of credit with Bridge Bank that was provided to the landlord of the College Road facility as security and cash of $16,499 that the Company is obligated to maintain as collateral for the credit limit on the Company’s credit card accounts.

Accounts Receivable and Allowance for Credit Losses

Trade accounts receivable consist of amounts due from direct customers, distributors and agencies of the U.S. government and are presented at net realizable value. At each balance sheet date, the Company estimates an expected allowance for credit losses inherent in the Company’s accounts receivable portfolio based on historical experience, specific allowances for known troubled accounts, and other available evidence. In addition, also at each reporting date, this estimate is updated to reflect any changes in credit risk since the receivable was initially recorded. This estimate is calculated on a pooled basis where similar risk characteristics exist. The Company has identified the following portfolio segments: direct customers, distributors/strategic partners and the U.S. government.

A fixed reserve percentage for each pool is derived from a review of the Company’s historical losses in relation to the total pool. This estimate is adjusted quarterly for management’s assessment of current conditions, reasonable and supportable forecasts regarding future events, and any other factors deemed relevant by the Company. The Company believes historical loss information is a reasonable starting point in which to calculate the expected allowance for credit losses as the Company’s portfolio segments have remained constant over the Company’s historical evaluation period.

The Company writes off receivables when there is information that indicates the debtor is facing significant financial difficulty and there is no possibility of recovery. If any recoveries are made from any accounts previously written off, they are recognized as an offset to credit loss expense in the year of recovery. The total amount of write-offs was immaterial to the financial statements as a whole for the three months ended March 31, 2024.

The allowance for credit losses reflects accounts receivable balances that are written off when management determines they are uncollectible.

The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist, and measures the allowance for credit losses using the following methods:

Direct Customers—The Company measures expected credit losses on direct customer receivables using an aging methodology. The risk of loss for direct customer receivables is low based on the Company’s historical experience. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and supportable forecasts.

Distributors/Strategic Partners—The Company measures expected credit losses on distributor receivables using an individual reserve methodology. The risk of loss in this portfolio is low based on the Company’s historical experience. The estimate of expected credit losses considers the past payment history of each distributor.

U.S. Government— These receivables are related to the Company’s government grants. The Company measures expected credit losses on these receivables using an individual reserve methodology. The risk of loss in this portfolio is very low based on the Company’s historical experience, as these receivables are supported by approved grant award contracts.

Inventories

Inventories are valued at the lower of cost or net realizable value under the first in, first out (FIFO) method. At March 31, 2024 and December 31, 2023, the Company’s inventory was comprised of finished goods, which amounted to $2,013,420 and $2,155,457, respectively; work in process which amounted to $1,107,630 and $838,871, respectively; and raw materials, which amounted to $617,717 and $685,801, 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. Donated devices are removed from inventory and charged to selling, general and administrative expenses.

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. During the three months ended March 31, 2024 and 2023, the Company recorded an impairment charge of approximately $64,000 and $111,000, respectively, related to the impairment of certain issued patents and pending patent applications in certain specific jurisdictions and the abandonment of certain pending patent application costs in the ordinary course of business. This charge is included in legal, financial and other consulting in the consolidated statements of operations and comprehensive loss.

Revenue Recognition

Revenue is recognized when the Company ships its products to its direct customers and distributors/strategic partners. Revenue is recognized on its grant awards with agencies of U.S. government in accordance with the terms of the award contract. See Note 4 for a description of the types of government contracts. The amount of revenue recognized reflects the consideration the Company expects to be entitled to receive in exchange for the products shipped or the services provided under their grant contracts. To achieve this core principle, the Company applies the following five steps:

Identify Contracts with Customers - The Company’s contracts with its direct customers are generally in the form of a purchase order. The Company has formal written contracts with each of its distributors/strategic partners that define their respective territories and minimum purchase commitments which must be met in order to maintain exclusivity in their territory. Distributors/strategic partner customers also submit purchase orders with each order that define the terms of shipment and transaction price. The Company has a contract for each grant award with various agencies of the U.S. government.

Identify Performance Obligations - The performance obligations in contracts with direct customers and distributors/strategic partners are for the shipment of the CytoSorb device and related accessory parts. The performance obligations for government contracts are dependent on the contract type, however, these are generally based on the costs incurred related to each government contract.

Table of Contents

Determine Transaction Price - The price charged is based on the Company’s price list for the CytoSorb device and related accessory parts for both direct customers and distributor/strategic partners. The Company does not permit returns for product sales. The Company also provides for certain rebates and discounts to direct customers for sales of its product that are earned based upon sales volume. These amounts, which are earned based on calendar year sales volume, are recorded as a reduction of sales as earned. The transaction prices for government contracts are dependent on the type of contract and are outlined in each contract.

Allocate Transaction Price to Performance Obligations - The transaction price for the performance obligation is based on the purchase orders received for both direct customers and on the type of contract and are outlined in each contract. The transaction prices for government contract performance obligations are dependent on the type of contract and are generally based on costs incurred.

Recognize Revenue as Performance Obligations are Satisfied - The Company satisfies its performance obligation to direct customers and distributors/strategic partners generally upon shipment of the products. The Company satisfies its performance obligations on government contracts generally upon incurring costs on each contract. The Company records deferred revenue related to fixed price government contracts to the extent that billings exceed costs incurred.

Research and Development

All research and development costs, payments to laboratories and research consultants are expensed when incurred.

Advertising Expenses

Advertising expenses are charged to activities when incurred. Advertising expenses amounted to approximately $45,000 and $55,000 for the three months ended March 31, 2024 and 2023, respectively, and are 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. In 2017, the Tax Cuts and Jobs Act reduced the U.S. federal corporate tax rate from 35% to 21%.

The Company follows accounting standards associated with uncertain tax positions. The Company had no unrecognized tax benefits at March 31, 2024. The Company is accounting for an uncertain tax position of approximate $2.1 million for the year ended December 31, 2023. 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 carryforwards to an industrial company.

CytoSorbents Europe GmbH, CytoSorbents Switzerland GmbH, CytoSorbents Poland Sp. z.o.o., CytoSorbents UK Limited, CytoSorbents Medical UK Limited, CytoSorbents India Private Limited and CytoSorbents France SAS file an annual corporate tax return, a VAT return and a trade tax return in Germany, Switzerland, Poland, France 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, liabilities at the date of the balance sheet, and the reported amounts of revenues and expenses during the

Table of Contents

reporting period. Actual results could differ from these estimates. The valuation of options granted, allowance for credit losses, and recoverability of patents are significant estimates 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 (“FDIC”). Beginning in April of 2023, the Company joined the IntraFi network, and established an Insured Cash Sweep (“ICS”) account whereby all cash that was previously held in the Company’s money market account at Bridge Bank is swept daily in increments of less than $250,000 and deposited in a number of IntraFi’s 4,000 member banks. This arrangement provides FDIC insurance coverage for all of the cash balances previously held in the money market account, which represents all of the cash and cash equivalents held at Bridge Bank. This arrangement excludes the restricted cash balances. Management monitors the soundness of these institutions in an effort to minimize its collection risk of these balances.

A significant portion of the Company’s revenues are from product sales in Germany. Substantially all of the Company’s 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 March 31, 2024, one distributor accounted for approximately 17% of outstanding grants and accounts receivable. As of December 31, 2023, one distributor accounted for approximately 19% of outstanding grants and accounts receivable. For the three months ended March 31, 2024, no customer accounted for more than 10% of the Company’s total revenue and for the three months ended March 31, 2023, one distributor accounted for approximately 11% 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.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480 “Distinguishing Liabilities From Equity” (“ASC 480”) and ASC 815 “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of equity at the time of issuance, and will remain as a component of equity thereafter. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded as liabilities at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations.

As the warrants issued upon the closing of the Company’s December 13, 2023 Offering meet the criteria for equity classification under ASC 815, the warrants are classified as equity as of March 31, 2024 and December 31, 2023.

Net Loss Per Common Share

Basic loss per share is computed by dividing loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted loss 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 stock options and restricted shares. The computation of diluted loss 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 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 other shipping and handling costs in cost of revenue. Total freight costs amounted to approximately $114,000 and $78,000, respectively, for the three months ended March 31, 2024 and 2023.

Effect of Recent Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40)” (“ASU 2020-06”). ASU2020-06 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The ASU is part of the FASB’s simplification initiative, which aims to reduce unnecessary complexity in U.S. GAAP. The ASU’s amendments are effective for fiscal years beginning after December 15, 2024, and interim periods within those fiscal years. The Company adopted the provisions of ASU 2020-06 on January 1, 2024. This did not have a material impact on the Company’s financial statements.

In December 2023, the FASB issued ASU No. 2023-09 entitled “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. This ASU provides guidance related to additional disclosures that will be required related to income taxes. The updated guidance is effective for public entities for fiscal years beginning after December 15, 2024. This ASU will result in additional disclosures in the Company’s consolidated financial statements related to income taxes in 2025.

The 2021 Shelf enables the Company to offer and sell, in one or more offerings, any combination of common stock, preferred stock, senior or subordinated debt securities, warrants and units, up to a total dollar amount of $150 million.

Open Market Sale Agreement with Jefferies LLC

On December 30, 2021, the Company entered into an Open Market Sale Agreement (the “Sale Agreement”) with Jefferies LLC (the “Agent”), pursuant to which the Company could 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 Agent, as the Company’s sales agent. All shares of the Company’s common stock offered and sold, or to be offered and sold under the Sale Agreement would have been issued and sold pursuant to the Company’s 2021 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.

Subject to the terms of the Sales Agreement, the Agent is 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 Agent 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. There were no sales pursuant to the Amended Sale Agreement during the year ended December 31, 2022. During the year ended December 31, 2023, the Company sold 2,656,464 shares pursuant to the Sale Agreement, at an average selling price of $1.76 per share, generating net proceeds of approximately $4,532,000.

These amounts are included in the consolidated statements of operations and comprehensive loss under selling, general and administrative expenses.

The summary of the stock option activity for the three months ended March 31, 2024, is as follows:


				Weighted

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. The following is a brief description of each revenue stream.

Table of Contents

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 EUA of CytoSorb for use in critically-ill patients infected with COVID-19 with imminent or confirmed respiratory failure by 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, Norway and the United Kingdom. Direct sales are fulfilled from the Company’s warehouse facility 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 versus 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.

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:

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.

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 upon 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.

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.

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.

These government contracts have terms ranging from three months to four years. The Company may apply for an extension of the term of the contract in order to complete its research and development activities but would not receive additional funding during the extension period in excess of the original contract. See Note 2 regarding the accounting policies related to these contracts.

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

Table of Contents

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:


	March 31, 2024		December 31, 2023
Contract receivables, which are included in grants and accounts receivable	$	4,974,578	$	3,846,271
Contract liabilities, which are included in accrued expenses and other current liabilities	$	1,595,652	$	1,577,141

Contract receivables represent balances due from product sales to distributors amounting to $4,538,868 and $3,270,724 at March 31, 2024 and December 31, 2023, respectively, and billed and unbilled amounts due on government contracts amounting to $435,710 and $575,547 at March 31, 2024 and December 31, 2023, respectively.

Contract liabilities represent the value of free of charge goods and credit rebates earned in accordance with the terms of certain direct customer agreements, which amounted to $191,727 and $196,322 at March 31, 2024 and December 31, 2023, respectively, and deferred grant revenue related to the billing on fixed price government contracts in excess of costs incurred, which amounted to $1,403,924 and $1,376,819 at March 31, 2024 and December 31, 2023, respectively.

5. LONG-TERM DEBT, NET

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 “Third Amendment 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, if needed. On January 19, 2022 (the “Fourth Amendment Closing Date”), the Company closed on the Fourth Amendment (the “Fourth Amendment”) of its Amended Loan and Security Agreement with Bridge Bank. Under the terms of the Amendment, the Company received a commitment from Bridge Bank to provide a new term loan of up to $15 million, if needed and entered into the Fourth Amendment Success Fee Letter (the “2022 Success Fee Letter”). On December 28, 2022 (the “Fifth Amendment Date”), the Company entered into the Fifth Amendment of its Amended Loan and Security Agreement with Bridge Bank. The Fifth Amendment extends the draw period under the Fourth Amendment to the earlier of (i) March 1, 2023 and (ii) the occurrence of an Event of Default. On March 9, 2023, the Company entered into the Sixth Amendment of its Amended Loan and Security Agreement. The Sixth Amendment further extends the draw period to March 24, 2023. Therefore, no further draws are available as of the date of this filing.

The Fourth Amendment provides a tranche of term loans (the “Term C Loans”) in the aggregate amount of $15 million, which are available for the Company to draw down at its sole discretion in three tranches of $5 million each at any time during the period commencing on the Fourth Amendment Date and ending on the earlier of (i) December 31, 2022 and (ii) the occurrence of an Event of Default (as defined in the Amended Loan and Security Agreement). The Term C Loans 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%. Pursuant to the Fourth Amendment, interest on the Term

Table of Contents

C Loans is subject to an interest rate cap of 8.00%. On December 27, 2022, the Company drew down the first $5 million tranche of the Term C loans available under the terms of the Fourth Amendment. Under the terms of the Fourth Amendment, commencing on February 1, 2023, the Company is required to make monthly payments of interest only through December 2023. The interest-only period will be further extended through June 2024 provided the Company has met both the required reserves test and the seventy-five percent test, as set forth in the Fourth Amendment, as of November 30, 2023. The Company did not meet the required reserves test as of November 30, 2023, and accordingly, commencing on January 1, 2024, the Company is required to make equal monthly payments of principal of $208,333, together with accrued and unpaid interest, through December 1, 2025 at which time the loan balance will be paid in full.

On the Fourth Amendment Closing Date, the Company was required to pay a non-refundable closing fee of approximately $18,750, which was amortized as a monthly charge to interest expense. On the Third Amendment Closing Date, the Company paid a non-refundable closing fee of $75,000, which was amortized 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 the Term Loan funded upon the earlier of the (i) the maturity date or (ii) termination of the Term Loans via acceleration or prepayment. This final fee is being accrued and charged to interest expense over the term of the loan. For each the three month periods ended March 31, 2024 and 2023, the Company recorded interest expense of approximately $10,700 related to the final fee. The Term Loans are evidenced by a secured promissory note issued to the Bank by the Company. If the Company elects to prepay the Term Loans pursuant to the terms of the Amended and Restated Loan and Security Agreement, it will owe a prepayment fee to the Bank, as follows: (1) for a prepayment made on or after the funding date of a Term Loan through and including the first anniversary of such funding date, an amount equal to 2.0% of the principal amount of such Term Loan prepaid; (2) for a prepayment made after the first anniversary of the funding date of a Term Loan through and including the second anniversary of such funding date, an amount equal to 1.5% of the principal amount of such Term Loan prepaid; and (3) for a prepayment made after the second anniversary of the funding date of a Term Loan, an amount equal to 1.0% of the principal amount of such Term Loan prepaid.

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.

2022 Success Fee Letter:

Pursuant to the 2022 Success Fee Letter, the Borrower will pay to the Bank a success fee equal to (i) 1% of $5 million if the Company draws down the first tranche of the Term C Loan and is payable only if the Company’s stock price equals or exceeds $8 for five consecutive trading days; (ii) 1.5% of $5 million if the Company draws down the second tranche of the Term C Loan and is payable only if the Company’s stock price equals or exceeds $10 for five consecutive trading days; and (iii) 2% of $5,000,000 if the Company draws down the third tranche of the Term C Loan and is payable only if the Company’s stock price equals or exceeds $12 for five

Litigation

The Company is, from time to time, subject to claims and litigation arising in the ordinary course of business. The Company intends to defend vigorously against any future claims and litigation.

On March 5, 2024, Danielle Greene, a former employee, filed a complaint against us in the Superior Court of New Jersey, Law Division, Mercer County, alleging breach of the New Jersey Conscientious Employee Protection Act (“CEPA”). The complaint specifically alleges that we violated the provisions of the CEPA by allegedly terminating Ms. Greene in retaliation for complaining about certain business practices. We dispute these allegations and intend to vigorously defend against them, but there can be no assurance as to the outcome of the litigation.

Royalty Agreements

Pursuant to an agreement dated August 11, 2003, an existing investor agreed to make a $4 million equity investment in the Company. These amounts were received by the Company in 2003. In connection with this agreement the Company granted the investor a perpetual royalty of 3% on all gross revenues received by the Company from the sale of its CytoSorb device which such rights were assigned to an existing investor in 2017. For the three months ended March 31, 2024 and 2023, the Company recorded royalty expenses of approximately $267,000 and $234,000, respectively. These expenses are included in selling, general and administrative expenses in the consolidated statements of operations and comprehensive loss.

On August 1, 2022, the Company entered into the Marketing Agreement with Fresenius, which expands the Company’s strategic partnership with Fresenius by establishing a multi-stage global collaboration to combat life-threatening diseases in critical care. The Marketing Agreement has an initial term of three years, with an automatic renewal for an additional two years at the end of such initial term, subject to earlier termination by either of the parties (the “Term”) To help support the increased marketing and promotional efforts of the expanded collaboration, the Company has agreed to subsidize a portion of the marketing costs through royalty payments to Fresenius. Initially, the Marketing Agreement provides for royalty payments equal to 0.9% of the Company’s net sales of CytoSorb products made during the Term (excluding net sales in the United States). This initial royalty rate was determined based on certain assumptions regarding the percentage of the Company’s sale of CytoSorb products that are used with the Fresenius critical care platforms in the intensive care unit outside of the United States but is subject to adjustment if the Company determines that the underlying assumptions have changed significantly. For the three months ended March 31, 2024, the Company did not record any expense related to this agreement. The launch of this program is expected to occur in 2024.

License Agreement

In an agreement dated September 1, 2006, the Company entered into a license agreement which provides the Company the exclusive right to use its patented technology and proprietary know - how relating to adsorbent polymers for a period of 18 years. Under the terms of the agreement, the Company has agreed to pay license fees of 2.5% to 5% on the sale of certain of its products if and when those products are sold commercially for a term not greater than 18 years commencing with the first sale of such product. For the three months ended March 31, 2024 and 2023 per the terms of the license agreement, the Company recorded licensing expenses of approximately $446,000 and $390,000, respectively. These expenses are included in selling, general and administrative expenses in the consolidated statements of operations and comprehensive loss.

7. 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 June 1, 2021. The Early Term commenced on June 1, 2021 and lasted until 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 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 multiplied by the Company’s share of the total building space (92.3%). The landlord will also provide an allowance of approximately

Table of Contents

$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 $1,467,000 as security. The Company has determined that this lease should be treated as an operating lease in accordance with the provisions of Accounting Standards Codification (“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 commenced on September 30, 2021, the Company will recognize rent expense on this lease on a straight-line basis over the remaining term of the lease for the difference between the rent expense recognized and the required payments under the lease.

In September 2021, the Company extended its two operating leases for its office facility in Germany. These leases require combined base rent payments amounting to approximately $12,100 per month. The initial lease term of both leases ends August 31, 2026. In addition, the Company is obligated to monthly operating expenses of approximately $3,000 per month. Both leases have a five-year option to renew that would extend the lease term to August 31, 2031. 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.

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:


	March 31,		December 31,
	2024		2023
Right-of-use asset	$	11,925,299	$	12,058,896

Total lease liability	$	13,182,625	$	13,270,295
Less current portion		(392,617)		(373,636)
Lease liability, net of current portion	$	12,790,008	$	12,896,659

The maturities of the lease liabilities are as follows as of March 31, 2024:


2025	$	1,666,361
2026		1,705,626
2027		1,745,970
2028		1,787,424
2029		1,830,017
Thereafter		14,950,174
Total lease payments		23,685,572
Present value discount		(10,502,947)
Total	$	13,182,625

For the three months ended March 31, 2024 and 2023, operating cash flows paid in connection with operating leases amounted to approximately $552,000 and $633,000, respectively.

As of March 31, 2024 and December 31, 2023, the weighted average remaining lease term was 12.4 and 12.7 years, respectively.

8. NET LOSS PER SHARE

Basic loss per share and diluted loss per share for the three months ended March 31, 2024 and 2023 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 warrants, options and restricted stock awards representing approximately 16,061,000 and 10,855,000 incremental shares as of March 31, 2024 and 2023, respectively, have been excluded from the computation of diluted loss per share as they are anti-dilutive.

9. SUBSEQUENT EVENTS

Overview

We are a leader in the treatment of life-threatening conditions in the intensive care (“ICU”) and cardiac surgery using blood purification via our proprietary polymer adsorption technology. We have a number of products commercialized and in development based on this technology platform. Our flagship product, CytoSorb^®, is already commercialized, and is being used to reduce deadly uncontrolled inflammation and dangerous substances in hospitalized patients around the world, with the goal of preventing or treating multiple organ failure, bleeding, and other potentially fatal complications. Organ failure is the cause of nearly half of all deaths in the ICU, with little to improve clinical outcome. CytoSorb is approved in the European Union (“EU”) as an 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, liver failure, cytokine release syndrome due to cancer immunotherapy, and pancreatitis. These are conditions where the mortality is extremely high, yet few to no effective treatments exist. 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 FDAgranted Breakthrough Device 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 EUA of CytoSorb for use in critically ill patients with COVID-19 infection and respiratory failure. In May 2020, we received a CE-Mark label expansion for CytoSorb for the removal of rivaroxaban during cardiothoracic surgery requiring cardiopulmonary bypass. In August 2021, the Company announced that it was granted a second Breakthrough Device Designation for its DrugSorb-ATR Antithrombotic Removal System by the FDA to remove the direct oral anticoagulants, rivaroxaban and apixaban. The Company has completed its pivotal randomized, controlled clinical trial in the U.S. and Canada, called the STAR-T trial, evaluating the use of DrugSorb-ATR during cardiothoracic surgery to prevent or reduce perioperative bleeding complications in pursuit of FDA and Health Canada marketing approval. We believe that the safety and efficacy results of the STAR-T trial will support regulatory submissions for marketing approval by the FDA and Health Canada.

CytoSorb is used during and after cardiac surgery to remove inflammatory mediators, such as cytokines, activated complement, and free hemoglobin that can lead to post-operative complications such as acute kidney injury, lung injury, shock, and stroke. We believe CytoSorb has the potential to be used in many other inflammatory conditions, including the treatment of autoimmune disease flares, cytokine release syndrome in cancer immunotherapy, and other applications in cancer, such as cancer cachexia. CytoSorb has been used globally in more than 237,000 human treatments to date in critical illnesses and in cardiac surgery. CytoSorb has received CE-Mark label expansions for the removal of bilirubin (liver disease), myoglobin (trauma) and both ticagrelor and rivaroxaban during cardiothoracic surgery. CytoSorb has also received FDA Emergency Use Authorization in the United States for use in critically-ill COVID-19 patients with imminent or confirmed respiratory failure, in defined circumstances. The EUA will be effective until a declaration is made that the circumstances justifying the EUA have terminated or until revoked by the FDA. CytoSorb has been used globally in more than 7,650 human treatments to date in COVID-19 patients. CytoSorb has also been granted FDA Breakthrough Designation for the removal of ticagrelor in a cardiopulmonary bypass circuit during emergent and urgent cardiothoracic surgery.

CytoSorb was also granted a second FDA Breakthrough Device designation for the removal of the Direct Oral Anticoagulants (DOACs) apixaban and rivaroxaban in a cardiopulmonary bypass circuit to reduce the likelihood of serious perioperative bleeding during urgent cardiothoracic surgery.

We are focusing on three key objectives that we believe are the key to driving sustainable, long-term growth:

•

Open the U.S. market by obtaining FDA Marketing approval for DrugSorb™-ATR to remove blood thinning drugs during cardiothoracic surgery (see Clinical Studies Update)

•

Grow core CytoSorb sales to profitability, driven by numerous internal initiatives (see Sales and Marketing Update)

•

Reduce cash burn and maintain tight control over expenses.

Our 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. The technology is protected by 21 issued U.S. patents and multiple international patents, with applications pending both in the U.S. and internationally. We have numerous other product candidates under development based upon this unique blood purification technology, including CytoSorb XL, K+ontrol, HemoDefend-RBC, HemoDefend-BGA, ContrastSorb, DrugSorb, DrugSorb-ATR and others.

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

•

CytoSorb — an extracorporeal hemoperfusion cartridge approved in the EU for cytokine removal, with the goal of reducing SIRS and sepsis and preventing or treating organ failure.

•

DrugSorb-ATR — an investigational extracorporeal antithrombotic removal system based on the same polymer technology as CytoSorb that is being evaluated in the U.S. STAR-T and future STAR-D pivotal randomized, controlled trials to reduce the level of antithrombotic drugs, ticagrelor, apixaban and rivaroxaban to reduce bleeding complications in patients undergoing cardiothoracic surgery while on these drugs.

•

ECOS-300CY — an adsorption cartridge approved in the E.U. for use with ex vivo organ perfusion systems to remove cytokines and other inflammatory mediators in the organ perfusate, with the goal of maintaining or improving solid organ function prior to transplant. In 2021, commercialization of PerSorb™ and Aferetica’s PerLife™ ex vivo organ perfusion system commenced in Italy.

•

CytoSorb XL — an intended next generation successor to CytoSorb currently in advanced pre-clinical testing designed to reduce a broad range of cytokines and inflammatory mediators, including lipopolysaccharide endotoxin, from blood.

•

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.

•

HemoDefend-RBC—a development-stage blood purification technology designed to remove non-infectious contaminants in blood transfusion products, with the goal of reducing transfusion reactions and improving the quality and safety of blood.

•

HemoDefend-BGA—a development-stage purification technology that can remove anti-A and anti-B antibodies from plasma and whole blood, to enable “universal plasma,” and safer whole blood transfusions, respectively.

•

K⁺ontrol—a development-stage blood purification technology designed to reduce excessive levels of potassium in the blood that can be fatal in severe hyperkalemia.

•

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.

Clinical Studies Update

For a complete discussion regarding our clinical study history, please refer to the section entitled Clinical Studies included in Item 1 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the SEC on March 14, 2024. The following includes certain updates regarding these clinical studies subsequent to the filing of the Company’s Annual Report on Form 10-K.

In July 2021, we received full FDA approval of an Investigational Device Exemption (IDE) application to conduct a double-blind, randomized, controlled clinical study in 120 patients entitled, “Safe and Timely Antithrombotic Removal – Ticagrelor (STAR-T),” in the United States to support FDA marketing approval. This was done under the previously announced FDA Breakthrough Device Designation granted for the removal of ticagrelor in a cardiopulmonary bypass circuit to reduce the likelihood of serious perioperative bleeding during urgent cardiac surgery. In October 2021, the first patient was enrolled, and the STAR-T study is now actively recruiting at multiple U.S. sites. In November 2022, the first milestone was completed with the first one-third of patients enrolled, triggering the first Data Safety Monitoring Board (DSMB) meeting. The DSMB recommended to continue the study as planned without any modifications. In 2022, we also received FDA approval to expand the study to Canada and subsequently received Health Canada approval allowing inclusion of Canadian sites into the STAR-T trial in January 2023. In early 2023, the study exceeded 50% enrollment and reached the 2nd milestone of 67% enrollment in the spring of 2023, triggering another DSMB safety review, which found no safety concerns and recommended completion of the trial. The study completed enrollment in July of 2023 triggering the final DSMB safety review following database lock in December 2023, which reported no safety concerns thereby meeting the primary safety endpoint of the study. Based on the initial analysis of the STAR-T data, the study did not meet the primary effectiveness endpoint in the overall patient population that underwent different types of cardiac surgeries. However, the study did demonstrate evidence of reduced bleeding complications, including serious bleeding events, in patients in the pre-specified isolated coronary artery bypass graft (“CABG”) surgery population. Patients undergoing CABG surgery represented more than 90% of the overall study population. The topline results of 140-patient, double-blinded, multicenter, pivotal STAR-T randomized, controlled trial were presented as a late breaking presentation at the 104th Annual Meeting of the American Association for Thoracic Surgery (AATS) held in Toronto, Canada on April 28, 2024. The Company believes the safety and effectiveness data from STAR-T will support the parallel regulatory submission of DrugSorb-ATR to the FDA and Health Canada in Q3 2024.

In October 2021, we also received full FDA approval of an Investigational Device Exemption (IDE) application to conduct a double-blind, randomized, controlled clinical study for up to 120 patients entitled, “Safe and Timely Antithrombotic Removal – Direct Oral Anticoagulants (STAR-D),” in the United States to support FDA marketing approval. This was done under the previously announced 2nd FDA Breakthrough Device Designation granted for our DrugSorb-ATR Antithrombotic Removal System. This Breakthrough Device designation covers the removal of the Direct Oral Anticoagulants (DOACs) apixaban and rivaroxaban in a cardiopulmonary bypass circuit to reduce the likelihood of serious perioperative bleeding during urgent cardiac surgery. The study has been postponed while the Company concentrates its clinical focus on STAR-T.

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 international Safe and Timely Antithrombotic Removal (STAR) Registry is designed to capture real world clinical and health economic outcomes with intraoperative antithrombotic drug removal. The Registry is actively recruiting in the U.K., Germany, Austria, Belgium and Sweden and is planned to expand to additional countries in 2024. Data outputs from the STAR Registry have already been reported at the EuroPCR 2023 conference in Paris in May 2023 and at the European Association of Cardiothoracic Surgery conference in Vienna in October 2023. The Registry has been enrolling well and will be reporting again new analyses with larger number of patients at both of the aforementioned conferences in 2024. Registry results will also be submitted for publication in major cardiovascular journals. on a rolling basis as enrollment progresses.

In April 2020, we received FDA Emergency Use Authorization for the treatment of adult critically ill COVID-19 patients with confirmed or imminent respiratory failure. The U.S. CytoSorb Therapy in COVID-19 (CTC) Registry was launched to capture outcomes and device utilization patterns from multiple U.S. participating centers. Initial results on critically ill COVID-19 patients on extracorporeal membrane oxygenation (ECMO) treated with CytoSorb at participating U.S. centers showed high survival rates (73%) compared with the international benchmark Extracorporeal Life Support Organization (ELSO) Registry. The initial CTC results on the first 52 critically ill patients from five U.S. ECMO centers were presented at the International Symposium of Intensive Care Medicine conference in August 2021 in Brussels, Belgium, and published in the peer reviewed journal Frontiers in Medicine. The CTC registry completed enrollment with 100 patients from five centers, and the final results mirror the high survival (74%) seen in the previous analysis, and have been published in the peer reviewed journal Critical Care. The data further demonstrate that earlier intervention with CytoSorb and ECMO was associated with shorter need for mechanical ventilation, ECMO, and ICU stay. These results lend support to our concept of “enhanced lung rest,” where ECMO helps the lungs rest by oxygenating blood extracorporeally and reducing the need for mechanical ventilation that can cause ventilator-induced lung injury, while CytoSorb reduces the circulating inflammatory mediators that cause continued capillary leak syndrome in the lungs. Together, the goal of this dual-therapy strategy is to give the lungs a chance to recover and heal, a pre-requisite for weaning off of mechanical ventilation and ECMO.

The German PROCYSS multicenter, randomized controlled trial evaluating the ability of CytoSorb to restore hemodynamic stability in patients with refractory septic shock is now currently enrolling. The speed of enrollment remains uncertain due to COVID-19 related institutional research staff shortages, however we anticipate conditions to gradually improve that together with a recently completed protocol amendment should help recruitment going forward.

The international COSMOS Registry was designed to capture real world outcomes and device utilization patterns across multiple critical care indications including but not limited to sepsis, acute respiratory failure, postoperative vasoplegia, acute liver failure, and acute pancreatitis. The Registry is actively enrolling in Spain, Germany and Italy with plans to expand in more countries in 2024. The intent of the Registry is to report outcomes at international conferences and submit the results for publication on a rolling basis as enrollment progresses. The first analysis of the Registry on the results in the first 100 patients enrolled was presented at the ISICEM meeting in Brussels in March 2024.

Sales and Marketing Update

The following are the key initiatives that we have been executing upon to drive product sales growth in the future.

Near-term growth drivers

•

Driving Greater Usage from a Strong Customer Base: Our core customer base accounts for the majority of our direct sales and grew by 20-25% at the start of the pandemic and has remained stable since We continue to educate and train centers on how best to use our therapy, highlighting new clinical data and applications. We believe this is a core strategy that will help to drive near-term growth.

•

New Therapy Divisions: We have established three distinct therapy divisions within our commercial operations including Critical Care, Cardiovascular, and Liver/Kidney/other to develop these markets internationally with the focus of leaders with area-specific medical and commercial expertise, who will work closely with our sales teams and best serve the needs and interests of our customers. The increased therapy area focus has already yielded good international sales momentum in many different areas, such as the use of CytoSorb in endocarditis and antithrombotic drug removal in cardiac surgery, in the treatment of liver disease, and in other critical care applications such as sepsis. We believe this infrastructure will yield many more similar successes across a broad array of applications.

•

Strategic Partnerships: We have entered into a global marketing agreement with Fresenius Medical Care, the largest dialysis company in the world, where CytoSorb has become the “featured solution for cytokine, bilirubin, and myoglobin removal” on its critical care platform of machines worldwide, with the exception of the U.S. Together, we are working to “Expand the Dimension of Blood Purification^®” in hospitals and to promote and market our respective kidney and liver replacement therapies around the world.

Table of Contents

•

New Exclusive Private Hospital Chain Partnerships: We are now the preferred supplier of hemoadsorption technology to the three largest private hospital chains in Germany, including Asklepios Kliniken GmbH, and the former hospitals of RHÖN-KLINIKUM AG. Many of these hospitals are already current customers and our agreements facilitate access and sales of CytoSorb to these and all other relevant institutions within these hospital networks.

•

Rise of Existing and New Applications: Among the many applications, we highlight:

o

Shock: Many studies have highlighted the ability of CytoSorb to remove inflammatory mediators and help to stabilize shock, a potentially fatal drop in blood pressure, in a wide range of patients. A recent 2019 meta-analysis, found that approximately 10% of ICU patients have septic shock at admission and 8% of patients admitted to the ICU have septic shock at some point in their hospital stay, with a high mortality of 38%. CytoSorb is being used around the world as a treatment of shock and we are conducting the PROCYSS RCT to formally evaluate CytoSorb as a treatment of this common and major unmet medical need.

o

Liver disease: In the treatment of acute liver disease, CytoSorb outperforms the market leading MARS® platform (Baxter) in the ex vivo removal of many liver toxins, but has the added benefit of removing cytokines and inflammatory mediators, while being much easier to use. In real-world practice, CytoSorb has replaced MARS at many accounts.

o

Lung Injury: Our U.S. CTC registry publication in Critical Care highlights the high survival of critically ill COVID-19 patients with acute respiratory distress syndrome (ARDS) treated with CytoSorb and ECMO under FDA Emergency Use Authorization. We believe these data demonstrate a therapeutic strategy of “enhanced lung rest” using the combined therapies that can be extrapolated to the treatment of ARDS in non-COVID patients, a very large market.

Longer-term growth drivers

•

Stand-alone blood pump strategy: There are many applications where a simple, low-cost hemoperfusion pump is adequate to implement our CytoSorb blood purification technology, without the complexity of a large dialysis or continuous renal replacement therapy (CRRT) machine, without the need for a dialysis technician, and where patients do not need to have failed kidneys. This would greatly simplify treatment with CytoSorb in the ICU - potentially enabling its more ubiquitous and earlier use on more patients while opening the door for more new applications in the emergency room, surgery suites, and elsewhere, in what we call the “hospital-wide” application. We expect to launch a new, easier to use pump manufactured by a third -party supplier in mid-2024 called PuriFi. The machine is only as good as the therapy that is being run on it, and CytoSorb is the market leading cytokine adsorbing technology that makes this an excellent combination treatment and a potentially game-changing new business model going forward.

•

Expansion of direct sales territories: Although opening new countries with a direct sales force requires time, cost, and effort, it also allows us to directly lead the effort, drive results, and benefit from more profitable sales. With the announcement of expansion of direct sales into the U.K., Ireland and France, we now sell direct in three of the E.U.’s Big 5 Economies - Germany, France and the U.K. - and a total of 15 countries direct overall, while working with distributors or partners in the other two Big 5 Economies: Italy, and Spain.

•

Investment in important clinical studies in shock, liver failure, cardiac surgery, ATR, etc: We are committed to funding Company-sponsored studies in key areas that we believe will drive international adoption and usage, with the goal of becoming a standard of care for those applications.

•

New Products: Over the past couple of years, there has been increasing momentum around two additional marketed products, ECOS-300CY for ex vivo organ perfusion (EVOP) in solid organ transplant under the EU CE mark, and VetResQ in the U.S. for the treatment of companion animals. In particular, prominent research in the field of heart, lung and liver organ transplant highlight the benefits of our technology in controlling inflammation and improving organ function during EVOP.

COVID-19 Business Update

COVID-19 patients develop life-threatening complications such as acute respiratory distress syndrome (ARDS), shock (i.e. a potentially fatal drop in blood pressure), kidney failure, acute cardiac injury, thromboses and emboli, and secondary bacterial infections. The underlying cause for these complications is often a massive, systemic inflammatory response, leading to the damage of vital organs such as the lungs, heart, and kidneys, and ultimately multiple organ failure and death in many cases. Hypercoagulability, thought triggered by inflammation, and resulting thromboembolic events such as pulmonary emboli and thrombotic microangiopathy, play another critical role in the pathophysiology of COVID-19 infection and severity of illness.

The use of CytoSorb in patients infected with COVID-19 in Italy, China, Germany and France began in March 2020. During the pandemic, CytoSorb has been used to treat dangerous inflammation and related life-threatening complications in more than 7,650 COVID-19 patients in more than 30 countries. Based upon initial data and reports from physicians treating these complications, CytoSorb use has generally been associated with a marked reduction in cytokine storm and inflammation, improved lung function, weaning from mechanical ventilation, decannulation from extracorporeal membrane oxygenation (ECMO), and a reversal of shock.

The use of CytoSorb has not been approved in the U.S. by the FDA. However, under certain circumstances, investigational medical devices that have not yet been FDA-approved may be made available for emergency use in the U.S. under the FDA’s Expanded Access Program (“EAP”). On April 13, 2020, we announced that the FDA, in a different program than the EAP, granted U.S. Emergency Use Authorization (EUA) of CytoSorb for use in adult critically ill COVID-19 patients. Under the EUA, CytoSorbents was able to make CytoSorb available, through commercial sales, to all hospitals in the U.S. for use in patients, 18 years of age or older, with confirmed COVID-19 infection who are admitted to the intensive care unit with confirmed or imminent respiratory failure and who have early acute lung injury or ARDS, severe disease, or life-threatening illness resulting in respiratory failure, septic shock, and/or multiple organ dysfunction or failure. The CytoSorb device has been authorized by FDA under an EUA. It 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.

The U.S. CTC (CytoSorb Therapy in COVID-19) Registry was launched to capture outcomes and device utilization patterns from multiple U.S. participating centers treating critically ill COVID-19 patients according to the treatment recommendations of the FDA Emergency Use Authorization (EUA). Preliminary results on observed ICU mortality of COVID-19 patients with acute respiratory distress syndrome (ARDS) requiring extracorporeal membrane oxygenation (ECMO) and treated with CytoSorb according to FDA EUA criteria were presented at the International Symposium of Intensive Care Medicine conference in September 2021 in Brussels, Belgium. In December 2021 and published in the peer-reviewed journal Frontiers in Medicine. The CTC Registry has completed enrollment and the final results confirming high survival (74%) were presented at the European Society of Intensive Care Medicine conference October 2022 and also have been published in the prestigious peer-reviewed journal Critical Care.

Government Research Grants:

We have historically 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 (“DARPA”), the U.S. Army, U.S. Special Operations Command (“USSOCOM”), the U.S. Air Force, Air Force Material Command (“USAF/AFMC”) and others. Currently, we have ongoing projects funded, in part, by the U.S. Army Medical Research Acquisition Activity (“USAMRAA”), the NHLBI, and the USAF/AFMC. For a complete discussion of the various research grants we have obtained, please refer to the section entitled Government Research Grants included in Item 1 of our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on March 14, 2024.

Research and Development Update

Our research and development work levels have returned back to pre-pandemic levels. As of March 31, 2024, the revenue remaining to be earned on open grant contracts is $5.0 million. Overall, grant funded programs, HemoDefend-BGA™ (Universal Plasma), HemoDefend-RBC™ and K⁺ontrol™, continue to progress and we have been the beneficiary of approximately $15.8 million, $4.7 million and $7.7 million in total funding, respectively, awarded to date.

Impact of Inflation and Other Issues:

The current high inflationary environment has impacted us in various ways. Due to the current competitive labor market and rising inflation, our labor costs have risen significantly in order to attract and retain qualified employees throughout our organization. In addition, we have experienced raw material price increases primarily related to the oil-based chemicals used in the polymer manufacturing process as well additional requests for higher fuel surcharges from most suppliers. Rising energy costs, including electricity and fossil fuels, have also made it more expensive to support our operations, manufacturing, and commercial activities. We have also experienced increases in our transportation costs; however, we have been able to substantially mitigate these cost increases by implementing bulk shipping methods. In addition, we have been able to mitigate most supply chain issues that existed during the COVID-19 pandemic by ordering larger quantities of inventory as they were available. Inflationary pressures may continue to impact our product gross margins in the future.

This decrease was due to a decrease in clinical trial costs of approximately $911,000 related to completion of the STAR-T trial in 2023, a decrease of approximately $850,000 in start-up expenses related to the new facility that were incurred in the first quarter of 2023 that did not recur in the first quarter of 2024, a decrease in non-grant related salaries of approximately $127,000 and a decrease in other non-grant related research and development activities of approximately $78,000.

Legal, Financial and Other Consulting Expenses:

Legal, financial and other consulting expenses were approximately $681,000 for the three months ended March 31, 2024, as compared to approximately $669,000 for the three months ended March 31, 2023, an increase of approximately $12,000. This increase was due to

an increase in accounting and auditing fees of approximately $46,000 and an increase in legal fees of approximately $30,000. These increases were offset by a decrease in employment agency fees of approximately $58,000 and a decrease in consulting fees of approximately $6,000.

Selling, General and Administrative Expenses:

Selling, general and administrative expenses were approximately $8,567,000 for the three months ended March 31, 2024, as compared to approximately $8,463,000 for the three months ending March 31, 2023, an increase of approximately $104,000. This increase was due to an increase in travel and entertainment expenses of approximately $132,000, an increase in royalty expense of $88,000, an increase in sales and marketing costs, which include advertising and conference attendance, of approximately $80,000. These increases were offset by decreases in non-cash stock compensation expense (which includes both stock options and restricted stock units) of approximately $156,000, and a decrease in salaries, commissions and related costs of approximately $40,000.

Gain (Loss) on Foreign Currency Transactions:

For the three months ended March 31, 2024, the loss on foreign currency transactions was approximately $1,426,000 as compared to a gain of approximately $661,000 for the three months ended March 31, 2023. The 2024 loss was directly related to the decrease in the spot exchange rate of the Euro to the U.S. dollar as of March 31, 2024 as compared to December 31, 2023. The spot exchange rate of the Euro to the U.S. dollar was $1.08 per Euro as of March 31, 2024, as compared to $1.11 per Euro as of December 31, 2023.

History of Operating Losses

We have experienced substantial operating losses since inception. As of March 31, 2024, we had an accumulated deficit of approximately $288,863,000, which included a loss of approximately $6,358,000 for the three-month periods ended March 31, 2024. Historically, losses have resulted principally from costs incurred in the research and development of our polymer technology, clinical studies, and general and administrative expenses.

Liquidity and Capital Resources

Since inception, our operations have been primarily financed through the issuance of debt and equity securities. As of March 31, 2024, we had current assets of approximately $19,993,000 and current liabilities of approximately $13,424,000. As of March 31, 2024, $25 million of our total shelf amount was allocated to our ATM facility, of which approximately $20.3 million is still available. During the three months ended March 31, 2024, the Company sold 53,290 shares pursuant to the Sale Agreement, at an average selling price of $1.03 per share, generating net proceeds of approximately $53,200.

In March of 2024, we received approximately $880,000 in cash from the approved sale of our net operating losses and research and development credits from the State of New Jersey.

We are also managing our resources proactively, continuing to invest in key areas such as our U.S. pivotal STAR-T trial, which includes the detailed analysis of trial data and the preparation of our application for marketing approval to the FDA. We have also instituted and continue to maintain tight control over expenditures.

As of March 31, 2024 we have approximately $10.1 million in cash, including approximately $8.6 million and $1.5 million in unrestricted and restricted cash, respectively. We believe this is sufficient to fund the Company’s operations into the fourth quarter of 2024. We will need to raise additional capital to support our ongoing operations in the future, and the Company is actively pursuing financing sources, including less or non-dilutive debt financing, royalty financing, strategic or direct investments, equity financing, and/or combinations thereof. There can be no assurance that management will be successful in these endeavors.

COVID-19 Impact on Financial Results

For the first year and a half of the coronavirus pandemic, COVID-19 was generally a positive driver for CytoSorb sales and highlighted the use of CytoSorb to treat cytokine storm and hyperinflammation. Because of this, the pandemic was a catalyst for CytoSorb orders from existing customers and also from new hospitals in countries where CytoSorb was not previously sold. We believe this awareness of CytoSorb increased overall usage during the COVID-19 pandemic and may help to drive further CytoSorb sales in the future.

Table of Contents

However, starting in the third quarter of 2021, the protracted COVID-19 pandemic began to have a negative impact on our business, due to pandemic-driven adverse market conditions worldwide, especially in Germany which is our largest market. The excessive workload in hospitals due to COVID has led to an exodus of healthcare workers from acute care worldwide, leaving hospitals short-staffed, particularly nursing. This in turn has forced the reduction in ICU beds and allowable patient censuses, and reduced the scheduling of revenue generating surgical procedures, resulting in decreased revenue and economic weakness at hospitals. Meanwhile, in 2022 the rates of severe COVID-19 illness requiring ICU care, and COVID-related death have been disproportionately very low. This is mainly attributed to high rates of vaccinations, natural immunity, and the availability of anti-viral drugs that are associated with reduced severity of illness, reduced need for hospitalization, and risk of death. These factors, in turn, have decreased the numbers of patients treatable with CytoSorb.

Additionally, COVID slowed our ability to generate clinical data to support our sales and marketing efforts. Currently, we are seeing an easing of the of the negative impacts of COVID-19. In 2024, we have generally good access to hospitals and physicians which should positively impact our product sales in the future. The lessened impact of COVID-19 has also had a positive impact on patient enrollment of our clinical trials.

Contractual Obligations

In March 2021, the Company 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 commencement date of the lease was April 1, 2021. The Initial Early Term began on the commencement date (April 1, 2021) and lasted two months. The Early Term commenced on June 1, 2021 and lasted until September 30, 2021. The lease also contains two five-year renewal options. Commencing on September 30, 2021, the remaining lease term will last for 15.5 years. The lease required 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. 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, multiplied by the Company’s share of the total building space (92.3%). The landlord also provided 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.

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, 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.

In September 2021, the Company extended its two operating leases for its office facility in Germany. These leases require combined base rent payments amounting to approximately $12,100 per month. The initial lease term of both leases ends August 31, 2026. In addition, the Company is obligated to monthly operating expenses of approximately $3,000 per month. Both leases have a five year option to renew that would extend the lease term to August 31, 2031.

Off-balance Sheet Arrangements

We have no off-balance sheet arrangements.

Going Concern

As of March 31, 2024, the Company’s total cash position was approximately $10.1 million, with cash and cash equivalents of approximately $8.6 million, and approximately $1.5 million in restricted cash, which is not expected to fund the Company’s operations beyond twelve months from the issuance of these financial statements. This matter raises substantial doubt about the Company’s ability to continue as a going concern. As a result, the accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company will need to raise additional capital to support our ongoing operations in the future.

Critical Accounting Policies and Estimates

A discussion of our critical accounting policies and estimates is contained in our Annual Report on Form 10-K.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Not applicable.

Item 4. Controls and Procedures.

We maintain disclosure controls and procedures designed to ensure information required to be disclosed in our reports filed under the Exchange Act, is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Interim Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation of our Chief Executive Officer and Chief Interim Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Interim Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report are functioning effectively to provide reasonable assurance that the information required to be disclosed by us in reports filed under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Interim Chief Financial Officer, as appropriate to allow timely decisions regarding disclosures. A controls system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the controls system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

No change in our internal control over financial reporting occurred during the three months ended March 31, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

We are not currently a party to any litigation or legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business. Regardless of outcome, litigation can have an adverse impact because of defense and settlement costs, diversion of management resources and other factors.
