1. NATURE OF BUSINESS AND BASIS OF PRESENTATION

CytoSorbents Corporation (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. based in New Jersey, 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, based in Berlin, Germany, its wholly-owned Indian subsidiary, CytoSorbents India Private Limited, based in Kasavanahalli, India, and its wholly-owned Dubai entity, CytoSorbents MEA FZCO, based in CommerCity, Dubai, conducts sales and marketing related operations for the CytoSorb device outside of the United States.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company as of June 30, 2026 and December 31, 2025, and for the three and six months ended June 30, 2026 and 2025. The Company’s condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X and therefore, do not include all information and footnotes necessary for a fair presentation of consolidated financial position, results of operations, and cash flows in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and should be read in conjunction with the audited consolidated financial statements of the Company for the year ended December 31, 2025, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. 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. The results for the three and six months ended June 30, 2026 and 2025, are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period. The Company presents amounts in thousands unless otherwise stated. Prior periods have been adjusted accordingly for consistent presentation. Certain prior year amounts in the footnotes have been reclassified to conform to the current year presentation.

Going Concern

As of June 30, 2026, the Company’s total cash and cash equivalents and restricted cash was approximately $5.9 million, with $1.5 million classified as restricted, and $4.4 million as unrestricted and available to fund operations. These cash and restricted cash balances considered with the Company’s historical and expected future cash used in operations, notwithstanding the Company’s Strategic Workforce and Cost Reduction Plan (see Note 11, “Restructuring”) and the impact of the Amended Loan and Security Agreement (see Note 6, “Long-Term Debt”) raises substantial doubt about the Company’s ability to continue as a going concern within twelve months after the date that the accompanying condensed consolidated financial statements are issued.

The Company’s expected future capital requirements may depend on many factors, including the ability to continue to reduce cash burn and achieve operating cash flow breakeven in the second half of 2026, expanding the Company’s customer base and sales force, the timing and extent of spending in obtaining regulatory approval and introduction of new products, including the potential regulatory approval and introduction of DrugSorb™-ATR, in the United States which would allow for the opportunity to receive Tranche 2 (b) of the Amended Avenue Capital Commitment by December 31, 2026 and receive an additional 6-month extension of the interest-only period on the credit facility, but which approval is now expected beyond this time frame. Additional sources of liquidity available to the Company include the 2024 Shelf, other public or private equity offerings, debt financing or from other sources. The sale of additional equity may result in dilution to shareholders. There is no assurance that the Company will be able to secure funding on terms acceptable, or at all. Although the Company has taken actions to achieve cash flow breakeven, if it does not achieve this goal, the potential need for capital could also make it more difficult to obtain funding through either equity or debt. Should additional capital not become available as needed, the Company may be required to take certain actions, such as slowing sales and marketing expansion, delaying further regulatory approvals, or further reducing headcount. The accompanying condensed 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 routinely evaluates other financing sources, including less or non-dilutive debt financing, additional grant funding, 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.
