- Cash and investments are sufficient to fund current operations through Q2 2027, not including VenoValve commercialization and the enVVe IDE study

- Cash burn of $4.2 million in Q3 remains in line with projected quarterly range

- Ongoing engagement with FDA for supervisory appeal of the VenoValve PMA decision with feedback expected by the end of 2025

IRVINE, CA / ACCESS Newswire / October 31, 2025 / enVVeno Medical Corporation (Nasdaq:NVNO) ("enVVeno Medical" or the "Company"), a company setting new standards of care for the treatment of deep venous disease, today reported financial results for the third quarter 2025.

Summary of Financial Results for the Third Quarter 2025

The Company ended the quarter with $31.0 million in cash and investments. With the VenoValve commercializations costs and enVVe IDE expenses currently on hold pending resolution with the FDA, this capital has the potential to fund the Company through the second quarter of 2027. The Company expects its cash burn rate to increase from current levels in the event the Company proceeds to commercialization of the VenoValve and the IDE study with enVVe.

Cash burn for the quarter was $4.2 million, consistent with the Company's projected cash burn rate of approximately $4-5 million per quarter.

The Company reported net losses of $4.5 million and $5.6 million for the three months ended September 30, 2025 and 2024, respectively, representing a decrease in net loss of $1.1 million, or 20%, due to a decrease in operating expenses of $1.3 million, partially offset by a decrease in other income of $0.2 million.

"We are well capitalized and should have sufficient capital to cover the period of our ongoing discussions with the FDA seeking a potential commercial path forward for the VenoValve and clarity for the enVVe IDE study," commented Robert Berman, CEO of enVVeno Medical. "Our recent in-person appeal meeting with the FDA provided a focused setting to address the concerns outlined in the not-approvable letter, including safety concerns raised by the FDA, proposed mitigations, the VenoValve's effectiveness, and also provided the opportunity for the Agency to hear directly from one of our primary investigators and a patient from the VenoValve study. We look forward to our continued interactions with the FDA and remain committed to the 2.5 million patients suffering from severe deep chronic venous insufficiency."
