Financial Performance: A Story of Transition and Challenge

NanoVibronix's financial performance for the three and six months ended June 30, 2025, reflects a company in transition, grappling with legacy challenges while integrating new operations. For the three months ended June 30, 2025, revenues declined by approximately 40% to $494 thousand from $817 thousand in the prior year, primarily due to reduced sales in the legacy NanoVibronix segment. The inclusion of ENvue's initial revenue helped mitigate a more severe decline. Gross profit turned negative, reaching -$35 thousand, a substantial decrease from $428 thousand in the same period of 2024. This was largely driven by a $159 thousand inventory write-off and $186 thousand in technology amortization. The net loss for the three months ended June 30, 2025, widened significantly to $3,971 thousand, a 477% increase from $688 thousand in the prior year.

For the six months ended June 30, 2025, consolidated revenues were $1,519 thousand, down 13% from $1,738 thousand in the same period of 2024. The NanoVibronix segment's revenues decreased by 21.35% to $1,367 thousand for the six months, primarily due to non-recurring high sales in 2024 from channels like Veteran Administration facilities and worker's compensation programs. The ENvue segment, acquired in February 2025, contributed $152 thousand in revenue for the six-month period. Operating losses were substantial across both segments, with NanoVibronix reporting a loss of $2,248 thousand and ENvue a loss of $2,019 thousand for the six months ended June 30, 2025. Consolidated research and development expenses surged by 388% to $1,502 thousand, largely due to a $624 thousand clinical trial program with the University of Michigan and $318 thousand from ENvue's operations. Selling and marketing expenses also increased by 193% to $1,066 thousand, with ENvue contributing $741 thousand. The overall net loss for the six months ended June 30, 2025, was $5,843 thousand, a 358% increase from $1,276 thousand in the prior year.

As of June 30, 2025, NanoVibronix reported an accumulated deficit of $75,988 thousand and continued to incur recurring losses and negative cash flows from operations, utilizing approximately $4,726 thousand in operating activities during the first six months of 2025. This financial strain has led management to express "substantial doubt regarding the Company’s ability to continue as a going concern for twelve months from the date of issuance of these interim condensed consolidated financial statements."

To address liquidity needs, the company has actively raised capital. Financing activities provided approximately $7,900 thousand in cash for the six months ended June 30, 2025, primarily from $8,215 thousand in net proceeds from a Series G Convertible Preferred Stock offering in May 2025. Subsequent to the quarter, in July 2025, the company secured an additional $8,000 thousand in gross proceeds from a private placement of Series H Convertible Preferred Stock. These capital infusions are critical for funding ongoing operations and strategic initiatives, but they underscore the company's reliance on external financing.

Strategic Initiatives and Future Outlook

The ENvue merger is central to NanoVibronix's future. The company is actively developing ENvue Drive™, an intelligent robotic platform for automated bedside enteral and vascular access, which could significantly enhance efficiency and safety in these procedures. An agreement with a New York Medical Center to implement ENvue™ Navigation Systems in Q3 2025 further validates the market potential of this technology. The recent U.S. patent for a pediatric feeding tube guidance system also strengthens ENvue's competitive position in a specialized, high-need area. These initiatives indicate a clear strategic direction to drive growth through innovation in enteral feeding.

The renewal and expansion of the exclusive three-year distribution agreement with Dukehill Healthcare Pty Ltd in Australia signifies a commitment to strengthening international sales channels for the legacy NanoVibronix products. This expansion beyond Queensland and New South Wales to cover all of Australia could provide a much-needed boost to the NanoVibronix segment's revenue. The appointment of Doron Besser, former CEO of ENvue Medical Holdings, LLC, as NanoVibronix's new CEO in June 2025, signals a strategic alignment with the newly acquired segment. This leadership change could facilitate a more focused integration and accelerated development of ENvue's product pipeline. The decision to withdraw the 510k clearance for PainShield MD Plus due to identified inaccuracies and halt future sales, while resulting in a $159 thousand inventory write-down, demonstrates a commitment to regulatory compliance and product integrity. Although it impacts the legacy product line, this move allows the company to reallocate resources and focus on more promising or compliant offerings.

Key Risks and Challenges

While NanoVibronix regained Nasdaq compliance in April 2025 after multiple reverse stock splits, it remains under a one-year mandatory panel monitor. If, within that monitoring period, the Staff finds the company again out of compliance with the Equity Rule, a Delist Determination Letter will be issued without further cure periods, severely impacting stock liquidity and access to capital. The recent Series G and Series H Convertible Preferred Stock offerings, while providing crucial capital, carry significant dilution risks for common stockholders. These preferred shares include anti-dilution provisions that could reduce their conversion prices in future equity offerings, potentially leading to an indeterminate number of common shares being issued upon conversion. The Series H Preferred Stock also carries a 15% per annum late fee, payable in cash, if common stock dividends cannot be paid, which could further strain liquidity.

The August 2025 1-for-10 reverse stock split, following a 1-for-11 split in March 2025, aimed to maintain Nasdaq listing. However, there is no assurance that these splits will sustainably increase the stock price or prevent future delisting. Reverse splits can also decrease stock liquidity and lead to stockholders owning "odd lots," potentially increasing transaction costs. The company is appealing an arbitration award of approximately $2.20 million (including interest) to Protrade Systems, Inc. An unfavorable outcome could result in a significant financial liability, impacting the company's already strained financial resources. Ongoing geopolitical conflicts and rising global inflation introduce significant uncertainties. These factors could disrupt supply chains, increase operational costs, impact international trade, and affect customer demand, particularly given NanoVibronix's international operations and R&D in Israel. As a medical device company, NanoVibronix faces inherent industry risks, including challenges in clinical trials, obtaining regulatory approvals, competitive product development, dependence on key personnel, intellectual property protection, and the continuous need for additional capital to fund operations.
