**ABOUT NANOVIRICIDES, INC.**

*This summary highlights selected information and does not contain all the information that is important to you. You should carefully read this prospectus, any applicable prospectus supplement and the documents we have referred you to in "Incorporation of Certain Documents by Reference" on page 9 of this prospectus for information about us and our financial statements as well as "Where You Can Find More Information" on page 8.*

*Except where the context otherwise requires, the terms "we," "us," "our," "the Company," or "NanoViricides" refer to NanoViricides, Inc.*

**OUR BUSINESS**

We are a clinical stage company with our first drug ready to enter Phase II human clinical efficacy trial, having successfully completed Phase Ia/Ib human clinical safety and tolerability trial. Based on our nanoviricides™ platform technology, we also have several additional drug candidates in various stages of pre-clinical development, including IND-filing stage and late stage IND-enabling non-clinical studies. We have no customers, products or revenues to date, and may never achieve revenues or profitable operations.

We are engaged in developing a class of drugs, that we call nanoviricides™, using a platform technology based on the application of nanomedicine technologies to the complex issues of viral diseases. This approach enables rapid development of effective new drugs against a number of different viruses, that the viruses are highly unlikely to escape even as they evolve rapidly in the field, solving an important problem in attacking viruses. The virus evolution is known to generate viruses that escape the traditional antiviral approaches vaccines, antibodies and small chemical drugs.

**<u>Broad and Expanding Pipeline Based on the Nanoviricide Platform Technology – in Brief</u>**

Our powerful Nanoviricides Platform technology has enabled us to develop several drug candidates against a large number of different viruses that could be further improved into clinical drug candidates, thus building a very broad drug pipeline that may lead to exponential growth of the Company upon the approval of our first drug candidate. While our first drug candidate, NV-387, is now in human clinical trials, and another one, NV-HHV-1, is awaiting to go into the clinic, over the years we have developed more than ten drug candidates that, we believe, can be rapidly moved into the clinical stage, for nearly forty different antiviral drug development programs. Our progress to clinic is limited by our resources. We anticipate that once our first drug goes successfully through Phase I and Phase II clinical trials thereby proving our capabilities and our Nanoviricides Platform technology, the Company, assuming it acquires the necessary financings, could enter a phase of exponential growth and rapid clinical development of additional candidates thereby transforming the way viral infections are treated.

We have several drugs in our pipeline, enabled by our strong and extensive nanoviricide technology platform. Of these, NV-387 has completed a Phase Ia/Ib Clinical Trial in healthy subjects with no adverse events reported in both the single-dose and multiple-dose portions of the clinical trial, and we have now received a draft Phase I report that is in quality review from the CRO and the clinical trial manager, Karveer Meditech Pvt. Ltd. Absence of any reportable adverse events is considered an excellent indication that the drug is safe and well tolerated in the Phase Ia/Ib clinical trial.

Presently, our focus is on the two separate Phase II clinical trials for NV-387 for the treatment of (i) MPox Virus Infection, and (ii) Viral Acute and Severe-Acute Respiratory Infections (Viral ARI and SARI). We are preparing the clinical trial application for the Phase II MPox trial and we have already obtained preliminary approval from the regulatory ethics committee for the clinical protocol in the Democratic Republic of Congo (DRC). In addition, we have already developed a draft clinical protocol for the Phase II Viral ARI and SARI clinical trial that is now in planning stage.

We plan on further commercial development of NV-387 as a pediatric RSV treatment once additional resources to support the RSV clinical program become available. We plan on re-engaging our HerpeCide program and our HIV program when sufficient resources become available.

We also plan on further developing NV-387 for the treatment of smallpox as a biodefense application, via the US FDA "Animal Rule". Our work in developing NV-387 for MPox is providing enabling datasets towards approval of NV-387 as a treatment for smallpox because both of these are orthopoxviruses. We are seeking non-dilutive funding for the development of NV-387 for smallpox, a bioterrorism threat.

Additionally, we believe that NV-387 may have effectiveness against many other viruses including viruses that do not have current treatments such as Henipaviruses (Hendra and Nipa viruses), filoviruses (Ebola and Marburg viruses), other hemorrhagic viruses of interest to the Department of Defense, among others. NV-387 mimics Sulfated Proteoglycans that more than 90% of human pathogenic viruses utilize as the first landing site in causing an infection. We plan on seeking collaborations with labs that can broadly test our drugs against multiple viruses as well as non-dilutive funding for such developments.

We also have several additional pre-clinical drug development programs including NV-HHV-1 and related candidates for Herpes Simplex Viruses (HSV-1 that causes cold sores, and HSV-2 that causes genital ulcers), NV-HIV-1 and related candidates for HIV/AIDS, other candidates for Influenza viruses and Dengue viruses, that we plan to advance further towards clinical drug candidates as they progress further when financial resources become available. Thus, we have a strong and broad pipeline that is expected to continue to result in highly effective drug candidates against a number of viral diseases.

We are now at the stage of clinically harnessing the development of Modality 1 and Modality 2 nanoviricides drugs. To recap, Modality 1 drugs mimic Attachment Receptors and possess a very broad spectrum of antiviral activity that includes a large number of different types of viruses. Modality 2 drugs mimic Cognate Receptors and possess a very strong antiviral activity against a set of specific types of viruses. In both cases, the targeted viruses are highly unlikely to escape the drug by evolving variants. NV-387, a Phase II-ready clinical stage drug candidate, is an example of Modality 1 nanoviricides,whereas NV-HHV-1 and NV+HHV-2 are examples of Modality 2 nanoviricides.NV-HHV-1 has completed IND-enabling studies as a Skin Cream for the treatment of Shingles.

We have also continued R&D on Modality 3 nanoviricide drugs that promise potential cures for non-latency viruses. As examples of this technology, NV-387-Rp and NV-387-Ribvp have shown strong effectiveness against Coronaviruses and RSV in animal models respectively, and are expected to be highly active against a number of other viruses based on the known activities of their components. We plan on developing these Modality 3 potential cures of a number of viral diseases after the Modality 1 and Modality 2 drugs.

Overall, since our founding, we have worked on development of approximately 40 different indications of different viral diseases in a number of drug development programs. In the process, we have built an extensive library of both the (i) Nanoviricides Platform know-how and (ii) the actual synthesized chemical drugs.

**REGISTERED DIRECT OFFERING OF SHARES OF COMMON STOCK AND PRE-FUNDED<br> WARRANTS, AND CONCURRENT PRIVATE PLACEMENT OF COMMON WARRANTS**

On November 10, 2025, the Company and a certain institutional investor (the "Investor") entered into a securities purchase agreement (the "Securities Purchase Agreement") pursuant to which the Company agreed to sell and issue to the Investor in a registered direct offering (the "Registered Direct Offering"): (i) 1,970,000 shares of Common Stock at an offering price of $1.68 per share, and (ii) pre-funded warrants (the "Pre-Funded Warrants") to purchase up to 1,601,429 shares of Common Stock, at an offering price of $1.67999 per Pre-Funded Warrant. Each Pre-Funded Warrant is exercisable for one share of Common Stock at an exercise price of $0.00001 per share, is immediately exercisable, and may be exercised at any time until exercised in full. Also pursuant to the Securities Purchase Agreement, in a concurrent private placement offering (the "PIPE," and collectively with the Registered Direct Offering, the "Offering"), the certain Selling Stockholder named herein was issued Series A Warrants to purchase up to 3,571,429 shares of Common Stock at an exercise price of $1.75 per share and Series B Warrants to purchase up to 3,571,429 shares of Common Stock at an exercise price of $2.00 per share.

Under the Registered Direct Offering, the Common stock were issued to investors pursuant to a prospectus supplement, filed with the SEC on November 12, 2025, to the registration statement File No. 333-271706 (the "Registration Statement"). The shares of Common Stock issuable upon exercise of the Pre-Funded Warrants were also being issued to investors pursuant to the prospectus supplement to the Registration Statement. The Common Warrants were issued to the Selling Stockholder in reliance upon the exemption from the registration requirements in Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), and Rule 506 of Regulation D promulgated thereunder.

Aggregate gross proceeds from the shares of Common Stock and Pre-Funded Warrants amounted to $6.0 million, before deducting the placement agent's fee and offering expenses payable by the Company.

The Series A Common Warrants are exercisable for $1.75 per share, beginning six months from the date of issuance and have a term of exercise equal to two years from the date of issuance. The Series B Common Warrants are exercisable for $2.00 per share, beginning six months from the date of issuance and have a term of five and one-half years from the date of issuance. The shares issuable upon exercise of the Common Warrants are being registered in this prospectus.

The Pre-Funded Warrants are exercisable immediately and may be exercised at any time until the Pre-Funded Warrants are exercised in full.

In connection with the PIPE offering, the Company agreed that within thirty (30) calendar days of such Agreement to file a registration statement providing for the resale by the investor of the Common Stock issued and issuable upon exercise of the Common Warrants (the "Resale Registration Statement"). The Company shall use commercially reasonable efforts to (a) cause the Resale Registration Statement to become effective within sixty (60) days (ninety (90) days in the event the Commission elects to review the Resale Registration Statement) following the filing date of the Resale Registration Statement, and (b) keep the Resale Registration Statement effective at all times until the investor no longer owns any Common Stock or Common Warrants.

**SELLING STOCKHOLDER**

7,142,858 shares of Common Stock being offered by the Selling Stockholder were previously issued to such Selling Stockholder pursuant to the Purchase Agreement dated November 10, 2025. In connection with the Offering, we provided registration rights within that certain Purchase Agreement with the Selling Stockholder whereby we agreed to register for resale the shares of Common Stock underlying the Common Warrants sold in the Offering. We are registering the shares of Common Stock underlying the Common Warrants in order to permit the Selling Stockholder to offer the Warrant Shares for resale from time to time.

The table below lists the Selling Stockholder and other information regarding the beneficial ownership (as determined under Section 13(d) of the Exchange Act, and the rules and regulations thereunder) of the shares of common stock held by the Selling Stockholder.

**PLAN OF DISTRIBUTION**

The Selling Stockholder and any of their pledges, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal trading market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. The Selling Stockholder may use any one or more of the following methods when selling securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

· block trades in which the broker-dealer will attempt to sell the Shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

· purchases by a broker-dealer as principal and resale by the broker-dealer for its own account;

· an exchange distribution in accordance with the rules of the applicable exchange;

· privately negotiated transactions;

· short sales effected after the date the registration statement of which this prospectus is a part is declared effective by the SEC;

· through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

· through agreements between broker-dealers and the seller stockholder(s) to sell a specified number of such Shares at a stipulated price per share;

· a combination of any such methods of sale; and

· any other method permitted by applicable law.

The Selling Stockholder may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholder may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholder (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the Selling Stockholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares of Common Stock in the course of hedging the positions they assume. The Selling Stockholder may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholder may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholder and any broker-dealers or agents that are involved in selling the Shares may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the Shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The Selling Stockholder has informed us that they do not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholder without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale Shares may not simultaneously engage in market making activities with respect to the Common Stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the Common Stock by the Selling Stockholder or any other person. We will make copies of this prospectus available to the Selling Stockholder and have informed it of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).
