Item 1A. Risk Factors

The baseline is this issuer’s latest earlier reporting period of the same form that was filed before the current report. A previous 10-Q is a different quarter, not a year-over-year comparison. Amendments are excluded.

Compared 16 previous paragraphs and 2 current paragraphs.

1 unchanged; 1 reworded; 0 added; 14 removed; 0 previous and 0 current paragraphs rearranged.

Tables are not compared: 6 previous and 0 current tables excluded. Dates, whitespace, punctuation and numbering changes are ignored; changes to financial figures remain significant.

A changed paragraph is not evidence that risk increased or decreased. An unchanged paragraph does not establish that risk stayed the same.

The current filing states there were no material changes to risk factors.

This is the filer’s own statement, not a conclusion from the comparison. Read its qualifications and the report it references.

Previous report

The following represent modification to risk factors that could materially harm our business, financial position, or operating results or could cause our actual results to differ materially from our anticipated results or other expectations, including those expressed in any forward-looking statement made in this report.

Previous report

We may not be successful in obtaining the FDA’s or Health Canada’s authorization and successful commercialization for DrugSorb-ATR in the U.S. or Canada, respectively

Previous report

On April 25, 2025, the FDA issued a denial letter regarding the Company’s De Novo Request for DrugSorb-ATR, identifying remaining deficiencies that must be addressed before the De Novo Request can be granted, and the device can be authorized for commercialization in the U.S. The Company filed an appeal of the decision through the formal appeal process with the FDA. In July, the Company participated in an appeal hearing with the FDA for supervisory review (administrative appeal) under 21 CFR 10.75. The appeal hearing included FDA senior leadership, Company management and our external surgical experts.

Previous report

On August 14, 2025, the Company received an FDA appeal decision following its July 2025 in-person supervisory administrative review (appeal) meeting with the FDA under 21 CFR 10.75. In the appeal decision, the FDA found no issues with device safety but upheld its prior De Novo denial decision citing the need for additional information to support the Company’s desired label indication. Additionally, the FDA proactively proposed a potential expedited path forward for market authorization but noted the Company could also appeal to a final higher level within the FDA with the Director of the FDA’s Center for Devices and Radiologic Health (CDRH). On September 16, 2025, the Company announced that it decided to not file a final appeal with the CDRH because of positive FDA upper management feedback for a reasonable path forward that would allow for a suitable and potentially expedited De Novo grant for the Company’s original desired label indication. The Company expects to file a new De Novo application with additional information that includes analyses of new real-world data to support its desired label indication in early 2026. As part of the resubmission process, the Company filed a pre-submission meeting request with supporting documentation to the FDA on November 7, 2025. A formal meeting with the FDA is anticipated in either late fourth quarter of 2025, or early 2026 to confirm the requirements for the new De Novo submission. A regulatory decision is expected in mid-2026 following a typical 150-day review process.

Previous report

On June 26, 2025, Health Canada issued a Notice of Refusal of the Company’s Medical Device License application, identifying remaining deficiencies that must be addressed before the application may be granted and the device authorized for commercialization. On September 16, 2025 the Company announced that it had timely filed a Level 1 “Request For Reconsideration” with Health Canada. However, following interactive discussions with the Medical Devices Directorate Bureau Director and the Company’s Canadian regulatory counsel, it was recommended that any subsequent review of DrugSorb-ATR in Canada be delayed until better clarity was received from the FDA. As such, the Company withdrew the Request for Reconsideration and will provide a new Medical Device License application to Health Canada with improved visibility from the FDA.

Previous report

We may be unsuccessful in our appeal which may significantly impact our ability to generate any significant revenues or ever achieve and maintain a substantial level of sales of our product candidates in the U.S. and Canada.

Previous report

Acceptance of our medical devices in the marketplace is uncertain, and failure to achieve market acceptance will prevent or delay our ability to generate revenues.

Previous report

Our future financial performance will depend, at least in part, upon the introduction, and customer and healthcare community acceptance of our products. Even with current or future regulatory or marketing approvals for our CytoSorb, ECOS-300CY, and PuriFi pump devices, other products like VetResQ, and product candidates such as DrugSorb-ATR, these products may not achieve market acceptance in the countries where they are sold. There is no guarantee that we will be able to achieve additional regulatory approvals, and even if we do, our products may not achieve market acceptance in the countries covered by such approvals. The degree of market acceptance will depend upon a number of factors, including:

Previous report

Physicians, patients, payers or the medical community in general may be unwilling to accept, utilize or recommend any of our products. For example, the approval of our CytoSorb device as a cytokine adsorber as well as the data we have gathered in our clinical studies to support device usage in this indication may not be sufficient for market acceptance in the medical community. We may also need to conduct additional clinical studies to gather additional data for marketing purposes. If we are unable to obtain regulatory approval or commercialize and market our products when planned, we may not achieve any market acceptance or generate revenue.

Previous report

If we are not in compliance with the continued listing standards of the Nasdaq Stock Market LLC (“Nasdaq”), our common stock may be delisted, which could have a material adverse effect on the liquidity of our common stock.

Previous report

Our common stock is listed on the Nasdaq Stock Market LLC (“Nasdaq”). On October 2, 2025, we were notified that we were not in compliance with the Nasdaq’s continued listing requirements relating to the minimum average closing price per share of our common stock, because the average closing price of our common stock over a consecutive 30 trading-day period was below $1.00 per share (the “Minimum Bid Price Requirement”).

Previous report

We have timely notified the Nasdaq of our intent to regain compliance with the minimum price condition within a 180-day cure period provided by Nasdaq rules, or until March 31, 2026 (the “Compliance Date”). We can regain compliance at any time within the cure period if, the closing bid price of the Company’s common stock meets or exceeds $1.00 per common share for a minimum of 10 consecutive business days prior to the Compliance Date, unless the Nasdaq staff exercises its discretion to require the Company to meet the Minimum Bid Price Requirement for a longer period pursuant to applicable Nasdaq rules. If we fail to regain compliance with the Nasdaq’s minimum price condition by the end of the cure period, the Company would be eligible for an additional compliance period of 180 days provided it presents an acceptable plan to Nasdaq to regain compliance.

Previous report

The Company intends to actively monitor the closing bid price of its common stock and will consider its options to regain compliance with the Minimum Bid Price Requirement. There can be no assurance that the Company will be able to regain compliance with the Minimum Bid Price Requirement or will otherwise be in compliance with other Nasdaq listing standards. If the Company is unable to regain compliance with the Minimum Bid Price Requirement, our common stock will be subject to the Nasdaq’s suspension and delisting procedures.

Previous report

During this time, our common stock will continue to be listed on the Nasdaq, subject to our compliance with other Nasdaq continued listing requirements. However, there can be no assurance about our ability to regain compliance with the Nasdaq’s minimum price condition within the applicable cure periods.
