### Overview

enVVeno Medical Corporation is a late clinical-stage medical device company focused on the advancement of innovative bioprosthetic (tissue-based) solutions to improve the standard of care for the treatment of deep venous disease. Chronic Venous Disease (CVD) is the world’s most prevalent chronic disease, impacting approximately 70% of the adult population of the U.S. Chronic Venous Insufficiency (CVI), is a large subset of CVD, which most often occurs when valves inside of the veins of the leg become damaged, resulting in the backwards flow of blood (reflux), blood pooling in the lower leg, increased pressure in the veins of the leg (venous hypertension) and in severe cases, venous ulcers that are difficult to heal. The Company is developing surgical and non-surgical replacement venous valves for patients suffering from severe CVI of the deep venous system of the leg.

The Company’s lead product is the VenoValve®, a potential first of its kind surgical replacement venous valve currently in post-enrollment follow-up of its U.S. pivotal study. The Company is also developing a second product called enVVe®, a potential next-generation, non-surgical, transcatheter based replacement venous valve. The Company is currently conducting pre-clinical testing on enVVe. Both the VenoValve and enVVe are designed to act as one-way valves, to help assist in propelling blood up the veins of the leg, and back to the heart and lungs.

The VenoValve and enVVe are being developed first for approval by the U.S. Food and Drug Administration (FDA). We expect the VenoValve to be eligible for FDA approval first, followed approximately three years later by enVVe. If approved, we expect the VenoValve and enVVe to co-exist, with the VenoValve as a surgical replacement venous valve option and enVVe as a non-surgical replacement venous valve option, although we cannot provide any assurance that either the VenoValve or enVVe will receive approval from the FDA (see the section entitled “Risk Factors” in our Annual Report on Form 10-K/A, filed with the SEC on February 28, 2025). There are currently no devices FDA approved as surgical or non-surgical replacement venous valves, and there are currently no effective treatments for deep venous CVI caused by incompetent valves.

Our team of officers and directors has been affiliated with numerous medical devices that have received FDA approval or CE marking and that have been commercially successful. We develop and manufacture our products in connection with our clinical trials in a 14,507 sq. ft. leased manufacturing facility in Irvine, California, which has been ISO 13485-2016 certified for the design, development and manufacturing of tissue based implantable medical devices.

### CVI Background

Chronic venous disease (“CVD”) is the world’s most prevalent chronic disease. CVD is clinically classified using a standardized system known as CEAP (clinical, etiological, anatomical, and pathophysiological). The CEAP system consists of seven clinical classifications (C0 to C6) with C4, C5 and C6 being the most severe categories of CVD.

Chronic Venous Insufficiency (“CVI”) is a large subset of CVD and is generally used to describe patients with C4 to C6 CVD. CVI is a debilitating condition that affects the venous system of the leg causing pain, swelling, edema, skin changes, and ulcerations.

The human leg contains three vein systems: the deep vein system, the superficial vein system, and the perforator vein system which connects the deep system to the superficial system. The deep venous system is located below the muscle and facia in the center portion of the leg and is responsible for approximately 90% of the blood flow. In order for blood to return to the heart from the foot, ankle, and lower leg, the calf muscle serves as a pump and pushes the blood up the veins of the leg against gravity and through a series of one-way valves. Each valve is supposed to open as blood passes through, and then close as blood progresses up the veins of the leg to the next valve. CVI occurs when the one-way valves in the veins of the leg fail and become incompetent. When the valves fail, gravity causes the blood to flow backwards and in the wrong direction (reflux). As blood pools in the lower leg, pressure inside the veins increases (venous hypertension). Reflux, and the resulting venous hypertension, causes the leg to swell, resulting in debilitating pain, and in the most severe cases, venous ulcers.

Severe CVI sufferers experience a significantly reduced quality of life. Daily activities such as preparing meals, housework, and personal hygiene (washing and bathing) become difficult due to reduced mobility. For many severe CVI sufferers, intense pain, which frequently occurs at night, prevents them from getting adequate sleep. Severe CVI sufferers with venous leg ulcers (VLU) are known to miss approximately 40% more workdays than the average worker without the condition. A high percentage of venous ulcer patients also experience severe itching, leg swelling, and an odorous discharge. Wound dressing changes, which occur several times a week, can be extremely painful. Venous ulcers from deep venous CVI are very difficult to heal, and a significant percentage of venous ulcers remain unhealed for more than a year. Even if healed, recurrence rates for venous ulcers are known to be high (20% to 40%) within the first year and as high as 60% after five years. Patients with severe CVI often become housebound and experience social isolation due to difficulty with ambulation. As a result, studies have shown that patients with active venous ulcers experience higher rates of anxiety and depression, with reported rates of anxiety of up to 30% and depression up to 40%. Rates of depression caused by venous ulcers among the elderly are even higher, with 48% of elderly venous ulcer patients having severe depressive symptoms.

Prevalence is generally defined as the portion of the population that has a given condition. Estimates indicate that the prevalence of people in the U.S. with severe, deep venous CVI (C4 to C6 disease) with reflux to be approximately 20 million. Incidence is generally defined as the number of new cases of an ailment that develop in a given time period. We estimate that approximately 3.5 million new patients with severe deep venous CVI are diagnosed each year in the U.S. including approximately 1.5 million patients that develop venous leg ulcers (C6 patients). The average patient seeking treatment of a venous ulcer spends as much as $30,000 a year on wound care, and the total direct medical costs from venous ulcer sufferers in the U.S. has been estimated to exceed $3 billion a year.

### VenoValve

The VenoValve is a surgically implanted replacement venous valve developed by enVVeno Medical, designed for use in the deep veins of the leg to treat severe CVI caused by valvular incompetence. By lowering pressure (venous hypertension) within the deep venous system of the leg, the VenoValve has the potential to reduce or eliminate the symptoms of severe deep venous CVI, including the potential to heal recurring venous leg ulcers. The VenoValve is implanted into the femoral vein of the patient in an open surgical procedure via a 5-to-6-inch incision in the upper thigh. The surgical approach for implanting the VenoValve is referred to as the SAVVE® procedure, which enables physicians to implant the VenoValve to restore valve function in the deep veins of the leg. As our planned initial entrant to the replacement venous valve market, we estimate that approximately 2.5 million people each year with severe deep venous CVI in the U.S. would be candidates for the VenoValve, including approximately 1.5 million people with active venous ulcers. The VenoValve has been granted Breakthrough Device designation by the FDA.

#### VenoValve Clinical Status

In March of 2021 we received IDE approval from the FDA to begin the VenoValve pivotal study. An investigational device exemption or IDE from the FDA is required before a medical device company can proceed with a pivotal trial for a Class III medical device. This approval allowed us to proceed with our U.S. pivotal study for the VenoValve, a prospective, non-blinded, single arm, multi-center clinical study. The seventy-five patient U.S. pivotal study reached full enrollment on September 1, 2023 and is now in the post-enrollment follow-up period.

The VenoValve is implanted using the SAVVE® procedure, an open surgical approach that enables precise placement of the device within the femoral vein to restore valve function. Efficacy endpoints for the U.S. pivotal study include rVCSS scores, which are used to provide evidence of clinically meaningful benefit, as well as reflux time measurements, VAS pain scores, quality of life measurements, ulcer healing (for CEAP class C6 patients), and intra-operative and one-year vein patency and valve functionality. Safety endpoints include device related events and procedure related events including mortality, pulmonary embolism, ipsilateral deep vein thrombosis, infection and bleeding.

In November 2024, one year efficacy and safety data from the U.S. pivotal study was presented at the 51th Annual VEITH Symposium. The data indicated that eighty-five percent (85%) of the patients enrolled in the trial experienced a clinical meaningful benefit from the VenoValve, defined as a three (3) or more point improvement in revised Venous Clinical Severity Score (rVCSS), at one year, compared to baseline. The average rVCSS improvement in the clinically meaningful responder cohort was 7.91 points. Patients in the study also experienced a seventy-five percent (75%) median reduction in pain and improvements in quality-of-life indicators. For patients with venous ulcers (CEAP C6 patients), ulcer area was reduced a median average of eighty-seven percent (87%). Over the course of the one (1) year period, there was one (1) death (unrelated to the VenoValve), zero (0) pulmonary embolisms, twelve (12) target vein thromboses, ten (10) surgical pocket hematomas, four (4) other bleeds, and seven (7) deep wound infections. Ninety-four percent (94%) of the patients that experienced a material safety event also went on to experience a clinically meaningful benefit from the VenoValve. Also, the reported target vein patency rates at thirty (30) days and one (1) year were ninety one percent (91%) and ninety seven percent (97%), respectively.

On November 19, 2024, the Company submitted the final module of its PMA application for review by the FDA. The VenoValve is designated as a breakthrough product and, as a result, its PMA application is subject to priority review. This may serve to shorten the PMA review process. Regardless, it is difficult to predict precisely how long the PMA process will take, and the Company’s best estimate is to expect an FDA decision during the second half of 2025.

### enVVe

On September 21, 2022, we announced the development of a non-surgical transcatheter based replacement venous valve called enVVe®, for the treatment of CVI of the deep veins of the leg. Initial preliminary bench testing and pre-clinical testing for enVVe have been successfully completed.

On December 16, 2024, we announced the successful completion of the final wave of implants for the six-month pre-clinical GLP study for enVVe. The first wave of implants, for the long-term subjects, was successfully completed in October 2024, and the final wave for the shorter-term subjects was completed in December 2024. The GLP study is a prerequisite to seeking IDE approval from the FDA to begin the enVVe U.S. pivotal study. The Company expects to file for IDE approval for the enVVe pivotal study in the third quarter of 2025.

### Capital

We finished 2024 with approximately $43.2 million of cash and investments and had approximately $38.9 million of cash and investments at March 31, 2025. Our future capital requirements will remain dependent upon a variety of factors, especially including the success of our clinical trials, related product development costs, and our ability to successfully bring products to market. We anticipate that our cash burn rate will increase from current levels of approximately $4 million to $5 million per quarter as we conduct our clinical trials and work toward bringing our product candidates to market.

### Results of Operations

### Comparison of the three months ended March 31, 2025 and 2024

#### Overview

We reported net losses of $4.5 million and $5.0 million for the three months ended March 31, 2025 and 2024, respectively, representing a decrease in net loss of $0.5 million, or 10%, resulting from a decrease in operating expenses, partially offset by a decrease in other income.

#### Revenues

As a developmental stage Company, our revenue, if any, is expected to be diminutive and dependent on our ability to commercialize our product candidates. We are not currently generating revenue and do not expect significant revenue until we successfully commercialize our product candidates after receiving FDA approval, if ever.

#### Research and Development Expenses

For the three months ended March 31, 2025, research and development expenses decreased by $0.5 million or 19%, to $2.6 million from $3.1 million for the three months ended March 31, 2024. This decrease primarily resulted from $0.5 million in lower costs related to the VenoValve pivotal study and $0.3 million in lower lab related costs. VenoValve pivotal study costs were lower as the amount of follow-up for each participant decreases over time. Lab costs were lower due to less assembly and test activity for the VenoValve once the VenoValve pivotal study reached full enrollment. These decreases were partially offset by a $0.3 million increase in personnel costs resulting from additional personnel.

#### Selling, General and Administrative Expenses

For the three months ended March 31, 2025, selling, general and administrative expenses decreased $0.1 million or 4%, to $2.4 million from $2.5 million for the three months ended March 31, 2024. The decrease was due to a $0.4 million decrease in share-based compensation, partially offset by $0.2 million in higher other compensation costs, and $0.1 million in higher consulting costs, both related to activities to prepare for potential commercialization of the VenoValve.

#### Other Income

For the three months ended March 31, 2025, other income decreased $0.1 million or 25% to $0.4 million from $0.5 million for the three months ended March 31, 2024. Other income in both periods reflects realized gains, interest, and unrealized gains and losses from our program to invest excess cash in US Treasury bills.

### Liquidity and Capital Resources

For the three months ended March 31, 2025, the Company incurred losses from operations of $5.0 million and used $4.0 million cash in operating activities. The net cash used in operating activities during the 2025 period increased by $0.4 million from $3.6 million for the quarter ended March 31, 2024.

The losses and the uses of cash are primarily due to our product research and development activities, including clinical studies, and administrative activities. Research and development activities are for continued product development and clinical studies for our product candidates, currently the VenoValve and enVVe. Administrative functions relate to costs to support our public reporting and investor relations activities, internal administrative functions and, starting in 2024, costs to prepare for commercialization of the VenoValve. The Company will continue to incur these costs, and we anticipate these costs will increase, as we work to complete our clinical studies, enhance products, develop new products, bring those products to market, and operate as a public company.

We are not currently generating revenue and do not expect significant revenue until we successfully commercialize one or more of our product candidates after receiving FDA approval, if ever.

We do not currently have material commitments for capital expenditures or other expenditures except for our facility lease commitment of $0.4 million per year. However, we expect a modest increase in purchases of property and equipment as we continue clinical studies, plan for commercialization of the VenoValve and continue development of enVVe.

Our future capital requirements will remain dependent upon a variety of factors, especially including the success of our clinical studies and related product development costs and our ability to successfully bring products to market. We anticipate that our cash burn rate will increase from current levels of approximately $4 million to $5 million per quarter as we conduct our clinical studies and work toward bringing our product candidates to market.

We have historically funded our operations through financing activities, such as the capital raise completed in 2024, and will need to raise additional capital in the future. Any inability to raise additional financing would have a material adverse effect on us.

Based on our cash and working capital as of March 31, 2025, we have sufficient capital resources to meet our obligations as they become due for at least one year after the date of this Quarterly Report and sustain operations.

### Critical Accounting Estimates

The preparation of our consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities, if any. Critical accounting estimates are those for which uncertainty about the assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities in future periods if the actual outcomes differ from estimates.

We do not have any matters that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next fiscal year.

### Off-Balance Sheet Arrangements

None.

### Contractual Obligations

As a smaller reporting company, we are not required to provide the information requested by paragraph (a)(5) of this Item.

## Market risk

As filed, 139 characters.

As a “smaller reporting company” as defined by Item 10 of Regulation S-K, we are not required to provide information required by this Item.

## Controls and procedures

As filed, 2,605 characters.

### Disclosure Controls and Procedures

Our management carried out an evaluation, under the supervision and with the participation of our Chief Executive Officer (who is our Principal Executive Officer) and our Chief Financial Officer (who is our Principal Financial Officer and Principal Accounting Officer), of the effectiveness of the design of our disclosure controls and procedures (as defined by Exchange Act Rules 13a-15(e) or 15d-15(e)) as of March 31, 2025, pursuant to Exchange Act Rule 13a-15(b). Based upon that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2025.

### Changes in Internal Control over Financial Reporting

During the three months ended March 31, 2025, there were no changes in our internal controls over financial reporting, or in other factors that could significantly affect these controls, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

### Inherent Limitations of Controls

Management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all error and all fraud. Controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or deterioration in the degree of compliance with the policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

## Risk factors
