Business Overview

Vivani Medical, Inc. ("Vivani," the "Company," "we," "us," "our" or similar terms) is a clinical stage biopharmaceutical company which develops miniature, ultra long-acting subdermal drug implants utilizing its proprietary NanoPortal™ technology, which is designed to enable ultra long-acting, near constant-rate delivery of a broad range of medicines to treat chronic diseases. Vivani uses this platform technology to develop and potentially commercialize drug implant candidates, alone or in collaboration with pharmaceutical company partners, to address leading causes of poor clinical outcomes in the treatment of chronic diseases, including medication non-adherence, drug tolerability and administration challenges faced by certain patients.

According to the U.S. Centers for Disease Control and Prevention, adherence is defined as the extent to which an individual's behavior, including taking medications, corresponds to recommendations from a health care provider. An alarmingly high proportion of patients, approximately 50%, do not, or cannot, take their medicine as prescribed in the real world, a statistic that applies to both daily oral as well as weekly injectable medicines. For example, a recent study has shown that 64% of patients taking Wegovy® (semaglutide injection) discontinue treatment within the first year, a number that increases to 76% by the second year. Unfortunately, GLP-1 discontinuation may result in failure to achieve target outcomes and a quick reversal of the health benefits in the majority of patients.

At Vivani, we are developing a portfolio of miniature, ultra long-acting subdermal drug implant candidates based on our NanoPortal technology that, unlike most oral and injectable medicines, are designed with the goal of guaranteeing medication adherence by delivering therapeutic drug levels for up to six months or longer. Our NanoPortal implant technology has the potential to reduce dosing frequency to 6 months or longer and allows for treatment to be discontinued at any time if necessary.In addition, we aim to minimize fluctuations in patients' drug levels which may improve the tolerability of medicines, including GLP-1 receptor agonists which produce side effects that are associated with fluctuating drug levels in the blood.

Our emerging portfolio of miniature, ultra long-acting drug implants have the potential to revolutionize the treatment of chronic diseases by directly addressing poor medication adherence and improving drug tolerability in patients, both of which have the potential to translate into better health outcomes for patients in the real-world setting. Vivani's lead program, NPM-139, is a miniature, six-month, GLP-1 (semaglutide) implant currently in development for chronic weight management in obese and overweight patients. NPM-139 recently achieved encouraging preclinical data in rats showing approximately 20% weight loss, as compared to a control group receiving sham implants, which was maintained for more than seven months. We are also developing NPM-133 (semaglutide implant) for the treatment of type-2 diabetes. Preliminary feasibility data support the additional potential benefit of once yearly dosing for both semaglutide implant programs, NPM-139 and NPM-133. In addition, we are also developing NPM-119 (exenatide implant) for the treatment of type 2 diabetes, NPM-115 (high-dose exenatide implant) for chronic weight management, and OKV-119, a GLP-1-based implant in development for chronic weight management and related conditions in companion cats and dogs. OKV-119 is being developed in collaboration with animal health partner Okava Pharmaceuticals, Inc. ("Okava").

Vivani resulted from the business combination of Second Sight Medical Products, Inc. ("Second Sight") and Nano Precision Medical, Inc. ("NPM"). On August 30, 2022, Second Sight and NPM completed their merger pursuant to which NPM became a wholly owned subsidiary of Second Sight and the combined company of NPM and Second Sight was renamed Vivani Medical, Inc. Vivani's main priority is the further development of its miniature, ultra long-acting drug implant programs. In parallel, Vivani's management team remains committed to identifying and exploring strategic options that will enable further development of its pioneering neurostimulation systems from legacy company Second Sight which are aimed at helping patients recover critical body functions. As noted below, we subsequently contributed our Second Sight assets and certain liabilities to Cortigent, Inc. ("Cortigent"), our wholly owned subsidiary to advance our pioneering neurostimulation technology.

Corporate Updates

On July 6, 2023, Vivani changed its state of incorporation from the State of California to the State of Delaware by means of a plan of conversion, effective July 5, 2023. The reincorporation, including the principal terms of the plan of conversion, was submitted to a vote of, and approved by, Vivani's stockholders at its 2023 Annual Meeting of Stockholders held on June 15, 2023. As part of this change of incorporation the Company established a par value of $0.0001 per share and all periods have been retroactively adjusted to reflect this change.

In the fourth quarter of 2023, Vivani Medical Australia Pty Ltd., a wholly owned subsidiary in Australia was established to support studies of our product candidates.

Preclinical and Platform Development

In February 2024, Vivani announced positive preclinical weight loss data with its exenatide implant, NPM-115, that was comparable to semaglutide, the active ingredient in Ozempic® and Wegovy®, and a strategic shift to prioritize the Company's obesity portfolio. In a study of high-fat diet-induced obese mice, the exenatide implant generated weight loss of approximately 20% compared to a sham implant control after a 28-day treatment duration, comparable to the extent of weight loss observed in mice treated with semaglutide injections in the same study.

In February 2024, the Company also disclosed that semaglutide, the active ingredient in Ozempic®, Wegovy® and Rybelsus®, is the active pharmaceutical ingredient in NPM-139, another miniature, ultra long-acting subdermal GLP-1 implant in development for chronic weight management, further prioritizing our obesity treatment portfolio. NPM-139 has the added potential benefit of once-yearly administration.

On May 28, 2024, Vivani announced the publication of positive weight loss data supporting the potential veterinary use of OKV-119, the Company's miniature, ultra long-acting GLP-1 implant under development with partner Okava for the treatment of pre-diabetes, diabetes and obesity in companion felines. The device is intended to be conveniently inserted under the skin during routine veterinary visits and is being designed to deliver six months of GLP-1 therapy with a single administration. We believe this six-month administration profile is important commercially in the veterinary setting due to the infrequent cadence of veterinary visits.

On September 4, 2024, Vivani announced positive preclinical liver fat results with its miniature, ultra long-acting GLP-1 implant currently under development for chronic weight management in obese and overweight individuals and type 2 diabetes. The Company's GLP-1 (exenatide) implant produced sham-implant adjusted liver fat reduction of 82% in an obese mouse model from a single administration with expected twice-yearly dosing. These liver fat data are consistent with published results from similar investigations with semaglutide.

Clinical Development

On July 14, 2023, we filed an Investigational New Drug Application ("IND") for NPM-119 (exenatide implant) with the U.S. Food and Drug Administration (the "FDA"), to support the initiation of a first-in-human study of our GLP-1 implant in patients with type 2 diabetes. On August 18, 2023, FDA provided written notification that the study was on full clinical hold, primarily due to insufficient Chemistry, Manufacturing, and Controls ("CMC") information to assess the risk to human subjects. The primary objective of this first-in-human clinical study was to evaluate the safety, tolerability and pharmacokinetics of NPM-119 in type 2 diabetes patients. This initial study design also incorporated Bydureon BCise® (exenatide injection) for comparison purposes.

On June 13, 2024, Vivani announced that the FDA cleared the IND and lifted the clinical hold for NPM-119, the Company's miniature, six-month GLP-1 implant under development for the treatment of patients with type 2 diabetes.

On July 11, 2024, the Company provided an update of the clinical development plans for NPM-115, the clinical program associated with the miniature, ultra long-acting GLP-1 (high-dose exenatide) implant for chronic weight management in obese and overweight individuals. The Company redesigned the first-in-human study, LIBERATE-1™, initially intended to explore the safety, tolerability and pharmacokinetics of its exenatide implant in patients with type 2 diabetes, to evaluate the implant in obese and overweight individuals.

On September 26, 2024, the Company reported receiving regulatory approval to initiate its first-in-human clinical trial with NPM-115, a miniature, ultra long-acting GLP-1 (exenatide) implant in obese and overweight individuals in Australia. This clinical trial, known as LIBERATE-1, investigated the safety, tolerability and full pharmacokinetic profile of our exenatide implant. The trial also represented the first clinical application of the Company's proprietary NanoPortal drug implant technology. LIBERATE-1 was redesigned to enroll participants who were titrated on weekly semaglutide injections for 8 weeks (0.25 mg/week for 4 weeks followed by 0.5 mg/week for 4 weeks) before being randomized to receive a single administration of Vivani's exenatide implant (n=8), weekly exenatide injections (n=8), or weekly 1 mg semaglutide injections (n=8) for a 9-week treatment duration. The trial was initiated at the end of 2024 with top-line data was released in August 2025.

On December 19, 2024, Vivani announced that screening and enrollment of LIBERATE-1, the First-in-Human clinical trial with a GLP-1 implant in obese and overweight patients, was initiated at two study centers in Australia. The primary objective of the study was to investigate the safety, tolerability and full pharmacokinetic profile of an exenatide implant in obese or overweight individuals.

On March 13, 2025, the Company announced the successful administration of its first GLP-1 (exenatide) implant in the LIBERATE-1 clinical trial. This milestone marked a critical step toward addressing one of healthcare's most pressing challenges: medication adherence in metabolic diseases including chronic weight management and type 2 diabetes. The Company also announced full enrollment in the LIBERATE-1 study, which was achieved in just four weeks after enrollment of the first subject, signaling early potential interest for this six-month, subdermal GLP-1 implant.

On August 5, 2025, Vivani announced plans to rapidly advance NPM-139, a novel semaglutide implant, based on promising results from the LIBERATE-1 clinical study and additional positive data from a preclinical study with a semaglutide implant. LIBERATE-1, the first-in-human application of Vivani's proprietary NanoPortal implant technology, demonstrated a positive safety and tolerability profile and encouraging performance data, thus meeting the study's primary objectives. This study provided information on the GLP-1 exposure levels obtained with an exenatide configuration, thereby paving the road for future clinical development of the technology, not only for exenatide implants (NPM-115 and OKV-119), but also for semaglutide implants (NPM-139 and NPM-133) and other applications of NanoPortal technology that the Company may pursue in the future. Vivani also announced new NPM-139 (semaglutide implant) preclinical feasibility data that demonstrated an approximately 20% weight loss with a single implant, which had been maintained for more than six months at the time of the announcement. This new semaglutide data also continues to support the potential for a semaglutide implant with annual dosing. Based on the LIBERATE-1 data supporting the clinical application of the NanoPortal platform technology, and the preclinical weight loss data with a semaglutide implant configuration, Vivani announced plans to prioritize advancement of NPM-139, with clinical development expected to begin in 2026.

On September 4, 2025, Vivani announced plans to initiate a Phase 1 clinical study for the NPM-139 semaglutide implant program in the first half of 2026, pending regulatory clearance, along with high-level details of the anticipated study design. The Company also announced parallel preparations to initiate a Phase 2 clinical study of NPM-139 pending enabling results from the Phase 1 study and regulatory feedback.

Cortigent, Inc.

In December 2022, we contributed our neurostimulation assets and certain liabilities from legacy company Second Sight to Cortigent, our wholly owned subsidiary to advance our pioneering neurostimulation technology. Cortigent had 5,000,000 shares of common stock outstanding, all owned by Vivani. On March 12, 2025, Vivani announced efforts to file a Form 10 with the U.S. Securities and Exchange Commission ("SEC") to support the spin-off of Cortigent into a fully independent, publicly traded company. Vivani announced the filing of the Cortigent Form-10 registration statement on May 29, 2025. The strategic goal of this transaction is to create two focused companies dedicated to driving current and future value in their respective therapeutic areas of expertise.

On August 25, 2023, the Company and Cortigent entered into an Amendment 1 (the "Amendment") to the Transition Funding, Support and Services Agreement dated March 19, 2023 (the "TFSSA"). Pursuant to the TFSSA, Vivani has agreed to advance funds and provide or cause to be provided to Cortigent the services and funding intended to cover salaries and related costs, rent and other overhead in order to permit Cortigent to operate in substantially the same manner as Second Sight prior to the formation of Cortigent. Efforts to support a successful initial public offering of Cortigent ceased in March 2025 and efforts are now focused on a potential spinoff with the filing of a Form 10 registration statement. The TFSSA terminated effective December 31, 2024. If the spinoff is successful, the loan payable from Cortigent to Vivani will be forgiven.

On May 29, 2025, Vivani announced that Cortigent had filed a Form 10 registration statement with the SEC to spin off Cortigent as an independent, publicly traded Nasdaq company. The strategic goal of this transaction is to create two focused companies dedicated to driving current and future value in their respective therapeutic areas of expertise. Vivani's board of directors authorized management to proceed with a plan to spin off its Cortigent neuromodulation business. The spin-off was planned to be completed during fourth quarter 2025, subject to the satisfaction of certain conditions, including, among others, final approval of Vivani's board of directors, receipt of a favorable opinion that the transaction will qualify for non-recognition of gain or loss as a result of receipt of Cortigent shares for U.S. Federal Income Tax purposes, and SEC and Nasdaq approval.

On September 17, 2025, Vivani announced that its board of directors had set a record date for the approved spin-off of Cortigent, Inc. Vivani stockholders holding common stock as of that record date would receive common stock in Cortigent. This record date was withdrawn on October 3, 2025, due to delays arising from the shutdown of the U.S. federal government. Vivani expects to reestablish a new record date as soon as possible.

Okava Pharmaceuticals, Inc.

On April 12, 2025, Vivani entered into an amendment to our License and Supply Agreement with Okava which expanded our ongoing collaboration to include dogs in the development of OKV-119, a long-acting GLP-1 therapy for weight management, type 2 diabetes, and other cardiometabolic conditions.

Liquidity and Capital Resources

Capital Funding

On March 1, 2024, the Company entered into the Securities Purchase Agreement relating to the issuance of 3,947,368 shares of the Company's common stock, par value of $0.0001 per share (the "common stock") and warrants to purchase up to an aggregate of 3,947,368 shares of common stock (the "Warrants"), at a purchase price of $3.80 per share and accompanying warrants in a registered direct offering (the "Offering"). The Warrants have an exercise price of $3.80 per share, are exercisable immediately upon issuance and will expire three years following the date of issuance. Simultaneously, the Company also entered into a placement agency agreement with Maxim Group LLC ("Maxim" and such agreement, the "Placement Agency Agreement," and together with the Securities Purchase Agreement, the "Agreements"), who acted as the sole placement agent for the Offering.

Non-Capital Funding

From time to time, we receive grants that help fund specific development programs. Any amounts received pursuant to grants are offset against the related operating expenses as the costs are incurred. Commencing in January 2018, we were awarded a grant from the National Institutes of Health (the "NIH") to fund the "Early Feasibility Clinical Trial of a Visual Cortical Prosthesis". The final year of the grant ended in March 2024, however the NIH issued us a no-cost extension allowing us to utilize the unfunded amount through March 2025. During the nine months ended September 30, 2025and 2024total grants offsetting against operating expenses were $0.0 million and$0.2 million, respectively. As of September 30, 2025, we expect $0will be available to offset future operating expenses.

Liquidity

We have experienced recurring operating losses and negative operating cash flows since inception and we expect to continue to incur operating losses and negative operating cash flows for the foreseeable future. To date, we have financed our working capital requirements through the recurring sale of our equity securities. Our financial statements have been presented on the basis that our business is a going concern and contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.

We estimate that currently available cash will provide sufficient funds to enable the Company to meet its planned obligations into 2027. Our ability to continue as a going concern is dependent on our ability to raise additional capital, however, there can be no assurances that we will be able to do so.

Our operating plan may change as a result of many factors currently unknown to us, and we will need to seek additional funds through public or private equity offerings or debt financings, grants, collaborations, strategic partnerships or other sources. However, we may be unable to raise additional capital or enter into such other arrangements when needed on favorable terms or at all. If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue one or more of our research or development programs, or we may be unable to expand or maintain our operations, maintain our current organization and employee base or otherwise capitalize on our business opportunities, as desired, which could materially and adversely affect our business, financial condition and results of operations.

We are subject to the risks and uncertainties associated with a business with no revenue that is developing a novel pharmaceutical product candidates and medical device candidates, including limitations on our operating capital resources and uncertain demand for our products. We expect our operating expenses to increase significantly as we continue our business operations, particularly as we prepare to initiate additional clinical trials and conduct our other research and development activities. Conducting clinical trials is a time-consuming, expensive and uncertain process that takes many years to complete, and we may never generate the necessary data or results required to obtain marketing approval. We do not expect revenues until we are successful in completing the development and obtaining marketing approval for our products. We expect expenses to increase in connection with our ongoing activities, particularly as we initiate clinical trials, initiate new research and development projects and seek marketing approval for any product candidates that we successfully develop. If we are required to conduct additional nonclinical or clinical activities, or IND-enabling activities, our overall expenditures would increase. In addition, if we obtain marketing approval, we expect to incur significant additional expenses related to sales, marketing, distribution and other commercial infrastructure to commercialize such product. In addition, our product candidates, if approved, may not achieve commercial success. We incur significant costs associated with operating as a public company in a regulated industry.

Until such time, if ever, we can generate product revenues, we anticipate that we will seek to fund our operations through public or private equity or debt financings, grants, collaborations, strategic partnerships or other sources. However, we may be unable to raise additional capital or enter into such other arrangements when needed on favorable terms or at all. To the extent that we raise additional capital through the sale of equity, convertible debt or other equity-linked securities, the ownership interests of some or all of our common stockholders will be diluted, the holders of new equity securities may have priority rights over our existing stockholders and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing common stockholders. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If adequate funds are not available, we may be required to curtail operations significantly or to obtain funds by entering into agreements on unattractive terms. If, for example, we raise funds through additional collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates, or to grant licenses on terms that may not be favorable to us. Our inability to raise capital could have a material adverse effect on our business, financial condition and results of operations.

Cash, cash equivalents and restricted cash decreased by $15.7million from $19.7 million as of December 31, 2024 to $4.0 million as of September 30, 2025. Working capitaldecreased by $17.1million from $14.5 million as of December 31, 2024to negative $2.7million as of September 30, 2025. We use our cash and cash equivalents and working capital to fund our operating activities.

Critical Accounting Policies and Estimates

The preparation of our condensed consolidated financial statements in conformity with generally accepted accounting principles in the United States ("GAAP") and the requirements of the United States Securities and Exchange Commission require management to make estimates, assumptions and judgments that affect the amounts, liabilities, revenue and expenses reported in the financial statements and the notes to the financial statements. On an ongoing basis, we evaluate our critical accounting policies and estimates. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Some of those judgments can be subjective and complex, and therefore, actual results could differ materially from those estimates under different assumptions or conditions.

There have been no material changes to our critical accounting policies during the three months ended September 30, 2025 compared to those disclosed in our Form 10-K for the year ended December 31, 2024.

Results of Operations

Operating Expenses. We recognize our operating expenses as incurred in two general operational categories: research and development and general and administrative. Our operating expenses also include a non-cash component related to the amortization of stock-based compensation for research and development and general and administrative personnel. From time-to-time we have received grants from institutions or agencies, such as the National Institutes of Health, to help fund some of the cost of our development efforts. We have recorded these grants as reductions to operating expenses.
