Customers
The company sells primarily to hospitals, intensive care units, and cardiac surgery teams that use its devices in acute, high-risk procedures. It also targets physicians, healthcare systems, and payers that must be convinced of clinical benefit, reimbursement value, and regulatory acceptance before broad adoption occurs.

Assess whether the therapy is reimbursed and economically justified, affecting adoption speed.
Buy VetResQ for animal critical care use, a smaller but strategically relevant niche.
Strategy
Management is focused on expanding commercial adoption while advancing regulatory approvals for DrugSorb-ATR in the U.S. and Canada. At the same time, the company is cutting costs, reducing headcount, and trying to reach cash-flow breakeven to reduce financing pressure and support continued development.
Approval would unlock a large new market and materially improve commercialization prospects.
Lower spending is needed to preserve liquidity and reach cash-flow breakeven.
Broader physician acceptance and guideline inclusion are needed for sustained sales growth.
The company already has regulatory access in Europe and many other countries, which remains its main revenue base.
Geography
Q1/2026CytoSorbents is headquartered in Princeton, New Jersey, but its commercial footprint is international, with CytoSorb distributed in more than 70 countries. The company’s core commercial base is outside the U.S., especially in Europe, while U.S. and Canadian growth depends on regulatory approvals that are still pending for key products such as DrugSorb-ATR.
Share of the revenue the company reports by geography.
Risks
The company is highly exposed to regulatory outcomes, especially for DrugSorb-ATR in the U.S. and Canada, where approval delays or denials could materially limit growth. It also faces adoption risk because hospitals, physicians, and payers may not accept the therapy without stronger clinical evidence, reimbursement support, and market education. Liquidity and going-concern pressure add financing risk, while competition and Nasdaq listing compliance remain additional business risks.
