May 21, 2026

255,699,381 Shares of Common Stock

This prospectus relates to the offering and resale by the Selling Stockholders listed herein of up to an aggregate of 255,699,381 shares of our common stock, par value $0.0001 per share (the “Common Stock”), consisting of (i) 85,223,129 shares of Common Stock issuable upon either (x) the conversion of 10,485 shares of our Series A Convertible Non-Redeemable Preferred Stock (the “Series A Preferred Stock”) into shares of Common Stock (the “Series A Conversion Shares”) or (y) the exercise of prefunded-warrants (the “Series A Preferred Pre-Funded Warrants”), issued upon conversion of the Series A Preferred Stock in lieu of the Series A Conversion Shares, to purchase up to 85,223,129 shares of Common Stock (the “Series A Preferred Pre-Funded Warrant Shares”, and together with the Series A Conversion Shares, the “Conversion Shares”); (ii) 85,223,126 shares of Common Stock issuable upon either (x) the exercise of Series B Common Stock Purchase Warrants (the “Series B Warrants ,” and such shares issuable upon exercise of the Series B Warrants, the “Series B Warrant Shares”) or (y) the exercise of prefunded-warrants (the “Series B Pre-Funded Warrants”), issued upon exercise of the Series B Warrants in lieu of the Series B Warrant Shares, to purchase up to 85,223,126 shares of Common Stock (the “Series B Pre-Funded Warrant Shares, and together with the Series B Warrant Shares, the “Series B Exercise Shares”); and (iii) 85,223,126 shares of Common Stock issuable upon either (x) the exercise of Series C Common Stock Purchase Warrants (the “Series C Warrants ,” and such shares issuable upon exercise of the Series C Warrants, the “Series C Warrant Shares”) or (y) the exercise of prefunded-warrants (the “Series C Pre-Funded Warrants”), issued upon exercise of the Series C Warrants in lieu of the Series C Warrant Shares, to purchase up to 85,223,126 shares of Common Stock (the “Series C Pre-Funded Warrant Shares”, and together with the Series C Warrant Shares, the “Series C Exercise Shares”). The Series B Warrants and the Series C warrants are collectively referred to as the “Warrants” and the Series B Warrant Shares, the Series C Warrant Shares, Series B Pre-Funded Warrant Shares and Series C Pre-Funded Warrant Shares are collectively referred to as the “Warrant Shares”.

The Conversion Shares and the Warrant Shares are collectively referred to as the “Shares”. For each Series A Preferred Pre-Funded Warrant to purchase a share of Common Stock we issue upon conversion of the Series A Preferred Stock, the number of Series A Conversion Shares we are offering will be decreased on a one-for-one basis such that we are offering a total of 85,223,129 Conversion Shares. For every Series B Pre-Funded Warrant to purchase a share of Common Stock we issue upon exercise of the Series B Warrants, the number of Series B Warrant Shares we are offering will be decreased on a one-for-one basis such that we are offering a total of 85,223,126 Series B Exercise Shares. For every Series C Pre-Funded Warrant to purchase a share of Common Stock we issue upon exercise of the Series C Warrants, the number of Series C Warrant Shares we are offering will be decreased on a one-for-one basis such that we are offering a total of 85,223,126 Series C Exercise Shares.

The Series A Preferred Stock and Warrants were sold to Selling Stockholders in our private placement that closed on March 20, 2026 (the “Private Placement”). In connection with the Private Placement, we entered into a registration rights agreement (the “Registration Rights Agreement”), which we are filing the registration statement, of which this prospectus forms a part, pursuant to.

The Selling Stockholders may sell or otherwise dispose of the Shares in a number of different ways and at varying prices. See “Plan of Distribution” for more information about how the Selling Stockholders may sell or otherwise dispose of the Shares. We are not selling any securities under this prospectus and will not receive any of the proceeds from the sale of shares of Common Stock by the Selling Stockholders. To the extent the Warrants are exercise for cash, if at all, we may receive aggregate gross proceeds of up to approximately $21 million. The Selling Stockholders and any broker-dealers or agents that are involved in selling the Shares, may be deemed to be an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act of 1933, as amended (the “Securities Act”).

Our Common Stock is listed on the NYSE American under the symbol “AZTR.” The last reported sale price of our Common Stock on the NYSE American on May 19, 2026, was $0.19 per share.

PROSPECTUS SUMMARY

This summary highlights certain information appearing elsewhere in this prospectus. Investing in our Common Stock involves a high degree of risk. Because it is only a summary, it does not contain all of the information that you should consider before investing in our Common Stock and it is qualified in its entirety by, and should be read in conjunction with, the more detailed information appearing elsewhere in this prospectus. Before you decide to invest in our Common Stock, you should read the entire prospectus carefully, including “Risk Factors” beginning on page 4 and the financial statements and related notes included in this prospectus or incorporated by reference.

About Azitra, Inc.

We are an early-stage clinical biopharmaceutical company focused on developing innovative therapies for precision dermatology using engineered proteins and topical live biotherapeutic products. We have built a proprietary platform that includes a microbial library comprised of approximately 1,500 unique bacterial strains that can be screened for unique therapeutic characteristics. The platform is augmented by an artificial intelligence and machine learning technology that analyzes, predicts and helps screen our library of strains for drug-like molecules. The platform also utilizes a licensed genetic engineering technology, which can enable the transformation of previously genetically intractable strains. Our initial focus is on the development of genetically engineered strains of Staphylococcus epidermidis, or S. epidermidis, which we consider to be an optimal therapeutic candidate species for engineering of dermatologic therapies. The particular species demonstrates a number of well-described properties in the skin. As of the date of this prospectus, we have identified among our microbial library over 60 distinct bacterial species that we believe are capable of being engineered to create living organisms or engineered proteins with significant therapeutic effect.

We are a pioneer in genetically engineering bacteria for therapeutic use in dermatology. Our goal is to leverage our platforms and internal microbial library bacterial strains to create new therapeutics that are either engineered living organisms or engineered proteins or peptides to treat skin diseases.

Our Corporate Information

Our principal executive offices are located at 21 Business Park Drive, Branford, Connecticut 06405, and our telephone number is (203) 646-6446. Our website address is www.azitrainc.com. The information contained in, or accessible through, our website is not incorporated by reference into this prospectus, and you should not consider any information contained in, or that can be accessed through, our website as part of this prospectus or in deciding whether to purchase our Common Stock or Warrants.

We own U.S. and foreign registered trademarks, including our company name. All other trademarks or trade names referred to in this prospectus are the property of their respective owners. Solely for convenience, the trademarks and trade names in this prospectus are referred to without the symbols ® and ™, but such references should not be construed as any indication that their respective owners will not assert, to the fullest extent under applicable law, their rights thereto.

Additional Information

For additional information related to our business and operations, please refer to the reports incorporated herein by reference, including our Annual Report on Form 10-K for the year ended December 31, 2025 as filed with the SEC on February 27, 2026, which we refer to as the 2025 Form 10-K, as described in the section entitled “Incorporation of Certain Documents by Reference” in this prospectus.

Implications of Being an Emerging Growth Company

The Jumpstart Our Business Startups Act, or the JOBS Act, was enacted in April 2012 with the intention of encouraging capital formation in the United States and reducing the regulatory burden on newly public companies that qualify as “emerging growth companies.” We are an emerging growth company within the meaning of the JOBS Act. As an emerging growth company, we may take advantage of certain exemptions from various public reporting requirements, including:

	●	the requirement that our internal control over financial reporting be attested to by our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act of 2002;
	●	certain requirements related to the disclosure of executive compensation in this prospectus and in our periodic reports and proxy statements;
	●	the requirement that we hold a nonbinding advisory vote on executive compensation and any golden parachute payments; and
	●	the ability to delay compliance with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standard.

We may take advantage of the exemptions under the JOBS Act discussed above until we are no longer an emerging growth company. We will remain an emerging growth company until the earliest to occur of (1) the last day of the fiscal year in which we have $1.235 billion or more in annual revenue; (2) the date we qualify as a “large accelerated filer,” with at least $700 million of equity securities held by non-affiliates; (3) the date on which we have issued, in any three-year period, more than $1.0 billion in non-convertible debt securities; or (4) the last day of the fiscal year ending after the fifth anniversary of the IPO.

We may choose to take advantage of some, but not all, of the available benefits under the JOBS Act. We have chosen to take advantage of all of the other exemptions discussed above. Accordingly, the information contained herein and in our subsequent filing with the SEC may be different than the information you receive from other public companies in which you hold stock.

Implications of Being a Smaller Reporting Company

Additionally, we are a “smaller reporting company” as defined in Rule 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company until the last day of the fiscal year in which (1) the market value of our Common Stock held by non-affiliates equals or exceeds $250 million as of the end of that year’s second fiscal quarter, or (2) our annual revenues equaled or exceeded $100 million during such completed fiscal year and the market value of our Common Stock held by non-affiliates equals or exceeds $700 million as of the end of that year’s second fiscal quarter.

RISK FACTORS

Any investment in our securities involves a high degree of risk. You should carefully consider the risks described below and set forth in the section “Risk Factors” in our 2025 Form 10-K, as well as any amendment or update to our risk factors reflected in subsequent filings with the SEC, which are incorporated by reference in this prospectus, and all other information contained in this prospectus and incorporated by reference in this prospectus, before you make a decision to invest in our securities. Please note that the risks highlighted here are not the only ones that we may face. For example, additional risks presently unknown to us or that we currently consider immaterial or unlikely to occur could also impair our operations. If any of the following events occur or any additional risks presently unknown to us actually occur, our business, financial condition and operating results may be materially adversely affected. In that event, the trading price of our Common Stock could decline and you could lose all or part of your investment.

Risks Relating to this Offering

Risks Related to this Offering

As an investor, you may lose all of your investment.

Investing in our securities involves a high degree of risk. As an investor, you may never recoup all, or even part, of your investment and you may never realize any return on your investment. You must be prepared to lose all of your investment.

We will need additional financing to execute our business plan and fund operations, which additional financing may not be available on reasonable terms or at all.

As of December 31, 2025, we had total assets of $5.0 million and working capital of $2.0 million. After giving effect to the offering, we believe that our cash on hand as of the date of this report will be sufficient to cover our proposed plan of operations for nine months. We intend to seek additional funds through various financing sources, including the sale of our equity, licensing fees for our technology and joint ventures with industry partners. In addition, we will consider alternatives to our current business plan that may enable us to achieve revenue producing operations and meaningful commercial success with a smaller amount of capital. However, there can be no guarantees that such funds will be available on commercially reasonable terms, if at all. If such financing is not available on satisfactory terms, we may be unable required to scale back our proposed plan of operations and we may be unable to continue operations, in which case you may lose your entire investment.

The report of our independent registered public accounting firm for the year ended December 31, 2025 states that due to our accumulated deficit, recurring and negative cash flow from operations there is substantial doubt about our ability to continue as a going concern.

The resale of the Shares offered pursuant to this prospectus (or the perception that such sales may occur) will result in substantial dilution and may materially and adversely affect the market price our Common Stock.

We are not selling any securities under this prospectus and will not receive any of the proceeds from the sale of Shares by the selling stockholders. We will likely only receive nominal proceeds of $0.0001 per share upon the cash exercise of the Pre-Funded Warrants. Though we would receive the proceeds for the cash exercise of the Warrants per their terms.

As of May 19, 2026, the Conversion Shares registered for resale by the Selling Stockholders in the registration statement of which this prospectus forms a part represented approximately 526% of the 16,192,438 shares of our Common Stock outstanding. If the Selling Stockholders exercise the Warrants in whole, they will receive an additional 170,466,252 Warrant Shares.

Our stockholders will experience substantial dilution upon the conversion of the Series A Preferred Stock and the exercise of the Warrants. Sales of a substantial number of shares of our Common Stock by the Selling Stockholders in the public market could occur at any time. Given the substantial number of shares being registered for potential resale by the Selling Stockholders pursuant to this prospectus, whether as a result of substantial sales of our Common Stock by the selling stockholders or the perception in the market that holders of a large number of Shares intend to sell their Shares, the market price of shares of our Common Stock could decline significantly and the volatility of the market price of our Common Stock could increase significantly, even if our research and development efforts are going well.

The market price of our shares may be subject to fluctuation and volatility. You could lose all or part of your investment.

The market price of our Common Stock is subject to wide fluctuations in response to various factors, some of which are beyond our control. Since shares of our Common Stock were sold in our initial public offering, or IPO, in June 2023 at a price of $999.00 per share, the reported high and low sales prices of our Common Stock have ranged from $1,034.96 to $0.10 through May 19, 2026. The market price of our shares on the NYSE American may fluctuate as a result of a number of factors, some of which are beyond our control, including, but not limited to:

	●	actual or anticipated variations in our and our competitors’ results of operations and financial condition;
	●	changes in earnings estimates or recommendations by securities analysts, if our shares are covered by analysts;
	●	market acceptance of our product candidates;
	●	development of technological innovations or new competitive products by others;
	●	announcements of technological innovations or new products by us;
	●	publication of the results of preclinical or clinical trials for our product candidates;
	●	failure by us to achieve a publicly announced milestone;
	●	delays between our expenditures to develop and market new or enhanced products and the generation of sales from those products;
	●	developments concerning intellectual property rights, including our involvement in litigation brought by or against us;
	●	regulatory developments and the decisions of regulatory authorities as to the approval or rejection of new or modified products;
	●	changes in the amounts that we spend to develop, acquire or license new products, technologies or businesses;
	●	changes in our expenditures to promote our product candidates;
	●	our sale or proposed sale, or the sale by our significant stockholders, of our shares or other securities in the future;
	●	changes in key personnel;
	●	success or failure of our research and development projects or those of our competitors;
	●	the trading volume of our shares; and
	●	general economic and market conditions and other factors, including factors unrelated to our operating performance.

These factors and any corresponding price fluctuations may materially and adversely affect the market price of our shares and result in substantial losses being incurred by our investors. In the past, following periods of market volatility, public company stockholders have often instituted securities class action litigation. If we were involved in securities litigation, it could impose a substantial cost upon us and divert the resources and attention of our management from our business.

Our failure to meet the continued listing requirements of the NYSE American could result in a delisting of our Common Stock.

On October 1, 2025, we received written notification from the NYSE American that we are not in compliance with Section 1003(a)(ii) of the NYSE American Company Guide. The Company has submitted a plan (the “Plan”) to regain compliance to the NYSE American and on December 16, 2025, received notice that the NYSE American had accepted the Company’s Plan to regain compliance and granted a plan period through April 1, 2027 (the “Plan Period Deadline”). If the Company does not regain compliance with the NYSE American continued listing standards by the Plan Period Deadline, or if the Company does not make progress consistent with its Plan during the plan period, then the NYSE American may initiate delisting proceedings. Additionally, if we fail to satisfy the continued listing requirements of the NYSE American, including the corporate governance requirements or the minimum closing bid price requirement, the NYSE American may take steps to delist our Common Stock. Such a delisting would likely have a negative effect on the price of our Common Stock and would impair your ability to sell or purchase our Common Stock when you wish to do so. In the event of a delisting, we can provide no assurance that any action taken by us to restore compliance with listing requirements would allow our Common Stock to become listed again, stabilize the market price or improve the liquidity of our Common Stock, prevent our Common Stock from dropping below the NYSE American’s minimum bid price requirement or prevent future non-compliance with the NYSE American’s listing requirements.

The Private Placement

Overview

On March 18, 2026, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with the Selling Stockholders, pursuant to which we issued the Selling Stockholders in the Private Placement an aggregate of (i) 10,485 shares of Series A Preferred Stock, (ii) Series B Warrants to purchase up to 85,223,126 shares of Common Stock, or Series B Pre-Funded Warrants in lieu thereof, and (iii) Series C warrants to purchase up to 85,223,126 shares of Common Stock, or Series C Pre-Funded Warrants in lieu thereof. The purchase price per share of Series A Preferred Stock, Series B Warrant to 85,223,126 shares of Common Stock, or Series B Pre-Funded Warrants in lieu thereof, and Series C Warrant to 85,223,126 shares of Common Stock, or Series C Pre-Funded Warrants in lieu thereof was $1,000. Each Share of Series A Preferred stock is convertible into 8,128.1 Series A Conversion Shares, or Series A Preferred Pre-Funded Warrants to purchase Series A Preferred Pre-Funded Warrant Shares.

The Private Placement closed on March 20, 2026 (the “Closing Date”).

The Private Placement could result in gross proceeds of up to approximately $31.4 million to the Company (assuming the cash exercise in full of the Warrants), including initial gross proceeds of approximately $10.5 million received by the Company on the Closing Date. The Company intends to use the initial net proceeds from the Private Placement, together with the Company’s existing cash and cash equivalents, to provide financing for research and development, general corporate expenses, and working capital needs.

Series A Preferred Stock

Subject to the terms and limitations contained in the Certificate of Designations, Preferences and Rights of Series A Convertible Non-Redeemable Preferred Stock (the “Certificate of Designations”), the Series A Preferred Stock is not convertible into Common Stock until the Company’s stockholders have approved each of (i) an increase in the number of authorized shares of Common Stock to enable the Company to issue all of the Conversion Shares, and (ii) the issuance of the Conversion Shares in accordance with the listing rules of the NYSE American (collectively, the “Stockholder Approval”). Effective as of 5:00 p.m. Eastern Time on the first business day after the date of the Stockholder Approval and subject to the Company filing an amendment to its Restated Certificate of Incorporation causing an increase in the number of authorized shares of Common Stock (the “Certificate of Amendment”), each share of Series A Preferred Stock will automatically convert into approximately 8,128.1 Series A Conversion shares, (the “Automatic Conversion”), subject to adjustment as provided in the Certificate of Designations and subject to a beneficial ownership limitation of 4.99%, 9.99% or 19.99% (as selected by the Selling Stockholder), of the number of shares of Common Stock Issued and outstanding (the “Series A Preferred Stock Beneficial Ownership Limitation”).

We will not effect any conversion of shares of Series A Preferred Stock in the Automatic Conversion to the extent that, after giving effect to the Automatic Conversion, a Purchaser would beneficially own a number of shares of Common Stock in excess of the Series A Preferred Stock Beneficial Ownership Limitation (the “Excess Shares”), and instead, we will issue such Purchaser a Series A Pre-Funded Warrant exercisable for the Excess Shares.

The Series B Warrants are exercisable following receipt of Stockholder Approval and the effectiveness of the Certificate of Amendment and will terminate eighteen months following the Stockholder Approval. The Series B Warrants have an exercise price of $0.123 per share of Series B Exercise Share.

The Series C Warrants will be exercisable following the receipt of Stockholder Approval and effectiveness of the Certificate of Amendment Filing, and will terminate 30 calendar days after the date the Company publicly announces data from its cosmetic filaggrin study in humans (the “Series C Termination Date”); provided, however, if the closing sale price of the Common Stock is below $0.123, the exercise price per Series C Exercise Share, then on the Series C Termination Date, the exercise price of the Series C Warrants shall automatically reset to the closing sale price of the Common Stock on such date (subject to a floor equal to 50% of the original exercise price of $0.123 per share), and the Series C Termination Date shall be extended by an additional 30 calendar days. If the closing sale price of the Common Stock is at or above the $0.123 exercise price on the Series C Termination Date, no extension shall apply.

The Warrants are subject to a beneficial ownership limitation of 4.99%, 9.99% or 19.99% (as selected by the Selling Stockholder), of the number of shares of Common Stock Issued and outstanding. If the exercise of a Warrant would cause the Selling Stockholder to exceed the ownership limitation, we will issue the Selling Stockholder a Series B Pre-Funded Warrant, in the case of Series B Warrants, or a Series C Pre-Funded Warrant, in the case of Series C Warrants.

Pre-Funded Warrants

The Series A Pre-Funded Warrants, Series B Pre-Funded Warrants and Series C Pre-Funded Warrants (collectively, the “Pre-Funded Warrants”) are all identical. They each have an exercise price of $0.0001 per share. Each Pre-Funded Warrant that may be issued in accordance with the Certificate of Designations and the Warrants will be exercisable immediately upon issuance and continuing through and including the date it is exercised in full.

USE OF PROCEEDS

We are not selling any shares of Common Stock in this offering and we will not receive any of the proceeds from the sale of Shares by the Selling Stockholders. The Selling Stockholders will receive all of the proceeds from any sales of the Shares offered hereby. However, we will incur expenses in connection with the registration of the Shares of our Common Stock offered hereby.

We will receive the exercise price upon any exercise of the Warrants, to the extent exercised on a cash basis. If all the Warrants were exercised for cash, we would receive gross proceeds of approximately $21 million. However, the holders of the Warrants are not obligated to exercise the Warrants, and we cannot predict whether or when, if ever, the holders of the Warrants will choose to exercise the Warrants, in whole or in part. Accordingly, any proceeds from such exercise will be used for general corporate purposes and working capital.

DIVIDEND POLICY

We have never declared or paid any cash dividends on our Common Stock and we do not anticipate paying any cash dividends on our Common Stock in the foreseeable future. Investors should not purchase our Common Stock with the expectation of receiving cash dividends. The payment of dividends on our Common Stock, if any, in the future is within the discretion of our Board and will depend on our earnings, capital requirements and financial condition and other relevant facts. We currently intend to retain all future earnings, if any, to finance the development and growth of our business.

SELLING STOCKHOLDERS

This prospectus covers the possible resale from time to time by the Selling Stockholders identified in the table below of Common Stock, including Common Stock issuable upon Conversion of the Series A Preferred Stock, the exercise of the Warrants, and the exercise of the Pre-Funded Warrants. The Selling Stockholders may sell some, all or none of their Common Stock. We do not know how long the selling stockholders will hold the Warrants and Pre-Funded Warrants, whether any will exercise such warrants, and upon such exercise, how long such Selling Stockholders will hold the Common Stock before selling them, and we currently have no agreements, arrangements or understandings with the Selling Stockholders regarding the sale of any of their shares. Additionally, we do not know when the Series A Preferred Stock will converted into Conversion Shares.

The table below sets forth, to our knowledge, information concerning the beneficial ownership of shares of our Common Stock by the selling stockholders as of May 19, 2026. The information in the table below with respect to the Selling Stockholders has been obtained from the respective selling stockholders. When we refer to the “Selling Stockholders” in this prospectus, or, if required, a post-effective amendment to the registration statement of which this prospectus is a part, we mean the Selling Stockholders listed in the table below as offering shares, as well as their respective donees, pledgees, transferees or other successors-in-interest. Throughout this prospectus, when we refer to the shares of our Common Stock being registered on behalf of the selling stockholders, we are referring to the shares of our Common Stock consisting of (i) 85,223,129 shares of our Common Stock upon conversion of the Series A Preferred Stock (or, in certain circumstances, Pre-Funded Warrants) and (ii) 170,466,252 shares of our Common Stock issuable upon the exercise of the Warrants (Series B Warrants to purchase 85,223,126 shares of our Common Stock and Series C Warrants to purchase 85,223,126 shares of our Common Stock) (or, in certain circumstances, Pre-Funded Warrants), without giving effect to the beneficial ownership limitations contained in the Series A Preferred Stock and the Warrants. The selling stockholders may sell all, some or none of the shares of Common Stock subject to this prospectus. See “Plan of Distribution” below as it may be supplemented and amended from time to time.

The number of shares of Common Stock beneficially owned prior to the offering for each selling stockholder includes (i) all shares of our Common Stock held by such Selling Stockholder as of May 19, 2026, (ii) all of the shares of our Common Stock issuable upon conversion of the Series A Preferred Stock held by such selling stockholder and (iii) all shares issuable upon the exercise of the Warrants held by such selling stockholder, in each case, without giving effect to the beneficial ownership limitations described above. The percentages of shares owned before and after the offering are based on 16,192,438 shares of Common Stock outstanding as of May 19, 2026, and assuming the issuance of 255,699,378 shares issuable pursuant to the conversion of the Series A Preferred Stock and exercise of the Warrants.

Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to our Common Stock. Generally, a person “beneficially owns” shares of our Common Stock if the person has or shares with others the right to vote those shares or to dispose of them, or if the person has the right to acquire voting or disposition rights within 60 days. The inclusion of any shares in this table does not constitute an admission of beneficial ownership for any Selling Stockholder named below.

However, for purposes of this table, we have assumed that, after completion of the offering, the Series A Preferred Stock is converted and each selling stockholder exercises their Warrants, and in each case the Selling Stockholder does not receive any Pre-Funded Warrants, and none of the shares covered by this prospectus will be held by the Selling Stockholders.

PLAN OF DISTRIBUTION

The Selling Stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of Common Stock or interests in shares of Common Stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of Common Stock or interests in shares of Common Stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The Selling Stockholders may use any one or more of the following methods when disposing of shares or interests therein:

	●	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 account;
	●	an exchange distribution in accordance with the rules of the applicable exchange;
	●	privately negotiated transactions;
	●	short sales and settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;
	●	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
	●	broker-dealers may agree with the selling stockholders 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 Stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of Common Stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

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

The aggregate proceeds to the selling stockholders from the sale of the Common Stock offered by them will be the purchase price of the Common Stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of Common Stock to be made directly or through agents. We will not receive any of the proceeds from this offering. Upon any exercise of the Warrants by payment of cash, however, we will receive the exercise price of the Warrants.

The Selling Stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule.

The Selling Stockholders and any underwriters, broker-dealers or agents that participate in the sale of the Common Stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the shares of our Common Stock to be sold, the names of the Selling Stockholders, the respective purchase prices and public offering prices, the names of any agents, dealers or underwriters, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the Common Stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the Common Stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the Selling Stockholders that the anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act:) may apply to sales of shares in the market and to the activities of the Selling Stockholders and their affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the Selling Stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the Shares offered by this prospectus.

We have agreed with the Selling Stockholders to use commercially reasonable efforts to cause the registration statement of which this prospectus constitutes a part to remain continuously effective until the earlier of (1) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with such registration statement or Rule 144 of the Securities Act or (2) the date on which all of the shares may be sold without restriction pursuant to Rule 144(c)(1) of the Securities Act.

Item 14. Indemnification of Directors and Officers.

The following summary is qualified in its entirety by reference to the complete text of any statutes referred to below and the Second Amended and Restated Certificate of Incorporation, or Certificate of Incorporation, of Azitra, Inc., a Delaware corporation.

Section 145 of the General Corporation Law of the State of Delaware (the “DGCL”) permits a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

In the case of an action by or in the right of the corporation, Section 145 of the DGCL permits a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses that the Court of Chancery or such other court shall deem proper.

Section 145 of the DGCL also permits a Delaware corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under Section 145 of the DGCL.

II-1

Our Certificate of Incorporation states that to the fullest extent permitted by the DGCL our directors shall not be personally liable to us or to our stockholders for monetary damages for breach of fiduciary duty as a director. If the DGCL is amended after the date hereof to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of our directors shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

Our Certificate of Incorporation requires us, to the fullest extent permitted by applicable law, to provide indemnification of (and advancement of expenses to) our directors and officers, and authorizes us, to the fullest extent permitted by applicable law, to provide indemnification of (and advancement of expenses to) to other employees and agents (and any other persons to which the DGCL permits us to provide indemnification) through bylaw provisions, agreements with such directors, officers, employees, agents or other persons, vote of stockholders or disinterested directors or otherwise, subject only to limits created by the DGCL with respect to actions for breach of duty to our corporation, our stockholders and others.

Our Certificate of Incorporation provides that we shall, to the maximum extent and in the manner permitted by the DGCL, indemnify each of our directors, officers and all other persons we have the power to indemnify under Section 145 of the DGCL against expenses (including attorneys’ fees), judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding, arising by reason of the fact that such person is or was a director of the Company. We may maintain insurance, at our expense, to protect the Company and any of our directors, officers, employees or agents against any such expense, liability or loss, whether or not we have the power to indemnify such person.

We have entered into indemnification agreements with each of our directors and executive officers that may be broader than the specific indemnification provisions contained in the DGCL. These indemnification agreements require us, among other things, to indemnify our directors and executive officers against liabilities that may arise by reason of their status or service. These indemnification agreements also require us to advance all expenses incurred by the directors and executive officers in investigating or defending any such action, suit, or proceeding. We believe that these agreements are necessary to attract and retain qualified individuals to serve as directors and executive officers.

Prior to the closing of this offering, we plan to enter into an underwriting agreement, which will provide that the underwriters are obligated, under some circumstances, to indemnify our directors, officers and controlling persons against specified liabilities.

Item 15. Recent Sales of Unregistered Securities.

The following list sets forth information regarding all unregistered securities sold by us over the three-year period preceding the date of the prospectus that forms a part of this registration statement.

In January 2022, we sold to one investor an unsecured convertible promissory note in the principal amount of $1.0 million. In January 2023, the principal amount of the note, along with all accrued interest, was converted into 3,518 shares of our Series B convertible preferred stock. Subsequently, these shares were converted into Common Stock upon the consummation of the IPO.

In September 2022, we conducted the placement of our unsecured convertible promissory notes in the aggregate principal amount of $4.35 million to five investors. The principal amount of the notes, along with all accrued and unpaid interest thereunder, converted into 9,239 shares of our Common Stock upon the consummation of the IPO.

No underwriters were involved in the foregoing issuances of securities. We believe the offers, sales and issuances of the above securities by us were exempt from registration under the Securities Act by virtue of Section 4(a)(2) of the Securities Act and Rule 506 thereunder as transactions not involving a public offering. All of the investors were accredited investors as such term is defined in Rule 501 under the Securities Act. The recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were placed upon the stock certificates, notes and warrants issued in these transactions. All recipients had adequate access, through their relationships with us, to information about our Company. The sales of these securities were made without any general solicitation or advertising.

II-2

On January 14, 2025, the Company entered into a placement agency agreement (the “January 2025 Placement Agency Agreement”) with Maxim Group LLC (“Maxim”) in connection with the offer and sale to investors of up to 729,381 shares (the “January 2025 Shares”) of the Company’s Common Stock, at an offering price of $2.00 per Share (the “January 2025 Offering”). In connection with the January 2025 Offering, the Company entered into a securities purchase agreement (the “January 2025 Purchase Agreement”) with certain of the purchasers in the January 2025 Offering. The aggregate gross proceeds to the Company from the January 2025 Offering were approximately $1.5 million, before deducting placement agent fees and other estimated offering expenses. The January 2025 Offering closed on January 16, 2025.

Maxim acted as the Company’s exclusive placement agent in the January 2025 Offering. Pursuant to the terms of the January 2025 Placement Agency Agreement, the Company agreed to pay Maxim a cash fee equal to 7.0% of the aggregate gross proceeds raised in the January 2025 Offering. The Company also agreed to reimburse Maxim for certain expenses. As additional compensation, the Company agreed to issue to Maxim (or its designees) an unregistered warrant (the “Placement Agent Warrant”) to purchase an aggregate of 29,175 shares of Common Stock (the “Placement Agent Warrant Shares”), which represents 4.0% of the aggregate number of Shares sold in the Offering, at an exercise price per share equal to 125% of the offering price of each Share, or $2.53. The Placement Agent Warrants are exercisable six (6) months from the date of issuance and expire five years from the commencement of sales in the January 2025 Offering. The Placement Agent Warrant may be exercisable via “cashless exercise” in certain circumstances.

The Placement Agent Warrants and the shares of Common Stock issuable upon exercise of the Placement Agent Warrants have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any state, and are being offered and sold in reliance on the exemption from registration under the Securities Act afforded by Section 4(a)(2) under the Securities Act and Regulation D promulgated thereunder as transactions by an issuer not involving any public offering.

On February 6, 2025, the Company closed an offering of 374,696 shares (the “February 2025 Shares”) of the Company’s Common Stock to certain investors (the “Investors”) pursuant to the Securities Purchase Agreement (the “SPA”) dated February 4, 2025, between the Company and the Investors, as amended on February 5, 2025. On February 6, 2025, in connection with the Investors’ agreement to enter into the amendment to the SPA, the Company and the Investors entered into a letter agreement (the “Letter Agreement”), pursuant to which the Company will (i) issue the Investors warrants to purchase up to 337,232 shares of Common Stock, in the aggregate (the “February 2025 Warrants”), and (ii) grant the investors a right for two years from the closing date of the Letter Agreement, to participate in future financings of the Company in an aggregate amount equal to 50% of such financings. Pursuant to the terms of the Letter Agreement, the Company filed a registration statement covering the issuance of the shares Common Stock underlying the February 2025 Warrants on July 18, 2025 (File No. 333-288766), which the SEC declared effective on July 23, 2025. The February 2025 Warrants are exercisable on the six-month and one day anniversary of their issuance, and their exercise price is equal to the greater of the (i) book value or (ii) market value of the Common Stock as determined under NYSE American Rules. The February 2025 Warrants and the shares of Common Stock issuable upon exercise of the February 2025 Warrants have not been registered under the Securities Act, or the securities laws of any state, and are being offered and sold in reliance on the exemption from registration under the Securities Act afforded by Section 4(a)(2) under the Securities Act and/or Regulation D promulgated thereunder as transactions by an issuer not involving any public offering.

On April 24, 2025, the Company entered into the ELOC Purchase Agreement with Alumni Capital, whereby the Company has the right, but not the obligation, to sell to Alumni Capital, and Alumni Capital is obligated to purchase up to the Investment Amount of shares of the Company’s Common Stock in a series of purchases. The purchase price of the shares that the Company elects to sell to Alumni Capital pursuant to the ELOC Purchase Agreement will be equal to the lowest daily volume weighted average price of the Common Stock during the period commencing on the date that the Company delivers a notice requiring the purchase of shares by Alumni Capital and ending on the earlier to occur of (i) five (5) business days immediately following such date and (ii) the date on which Alumni Capital notifies the Company that it is prepared to proceed with the relevant closing, multiplied by 90%. Upon each purchase, Alumni Capital receives warrants to purchase such number of shares of the Company’s Common Stock equal to 10% of the number of shares purchased in the related purchase. The exercise price of the warrants equals 130% of the price per share paid upon closing. The exercise of the warrants were subject to stockholder approval, which the Company received at its annual meeting of shareholders held on June 23, 2025, and expire five years after issuance. The warrants may be exercised via cashless exercise if there is no effective registration statement, or current prospectus available for, the resale of the shares underlying the warrants. The issuance of the shares and the warrants to Alumni Capital were or will be made pursuant to exemptions from the registration requirement of the Securities Act provided by Section 4(a)(2) thereunder. In accordance with the ELOC Purchase Agreement, the Company registered the offering and resale by Alumni Capital of up to 10,043,488 shares of the Company’s Common Stock and up to 1,004,349 shares underlying the warrants issuable upon exercise of the warrants on Form S-1 (File No. 333-286809), which was declared effective by the SEC on May 1, 2025.

On August 26, 2025, the Company entered into a Modification Agreement (the “Modification Agreement”) with Alumni Capital to amend certain terms of the ELOC Purchase Agreement. Pursuant to the Modification Agreement, the Company may at its election, cause Alumni Capital to make a series of purchases of ELOC Shares either at (i) the lowest daily volume weighted average price of the Common Stock during the period commencing on the date that the Company delivers written notice and ending on the earlier of (a) five (5) business days immediately following the date of a written notice, and (b) the date on which Alumni Capital notifies the Company that it is prepared to proceed with the closing of the purchase, multiplied by 90% (“Purchase Notice Option 1”) or (ii) the lowest traded price of Common Stock during the period commencing on the date the Company delivers a written notice and ending on the earlier of (x) the same business day a written notice is delivered, and (y) the date on which Alumni Capital notifies the Company that it is prepared to proceed with the closing of the purchase, multiplied by 97% (“Purchase Notice Option 2”). Each written delivered by the Company must specify whether Purchase Notice Option 1 or Purchase Notice Option 2 is selected and the number of shares of Common Stock to be purchased. All other terms and conditions of the Purchase Agreement remain in full force and effect.

The November Offering Price was $0.32 per share of Common Stock or November Pre-Funded Warrant and accompanying November Common Stock Purchase Warrant. The November Pre-Funded Warrants are immediately exercisable and do not expire until exercised in full. The November Common Stock Purchase Warrants are exercisable upon shareholder approval and will expire on the five-year anniversary of shareholder approval. The November Common Stock Purchase Warrants may be exercised via cashless exercise if, after the six month anniversary of the issuance date, there is no effective registration statement, or current prospectus available for, the resale of the shares underlying the November Common Stock Purchase Warrant. The issuance of the November Common Stock Purchase Warrants and November Pre-Funded Warrants to Alumni Capital were made pursuant to exemptions from the registration requirement of the Securities Act provided by Section 4(a)(2) thereunder.

In connection with the November Offering, on November 24, 2025, the Company entered into the November Placement Agency Agreement with the November Placement Agent, pursuant to which the Company engaged the November Placement Agent as the exclusive placement agent in connection with the November Offering. Pursuant to the November Placement Agency Agreement and as consideration for the November Placement Agent’s services thereunder, the Company agreed to, among other compensation described herein, issue the November Placement Agent Warrants to purchase 187,500 shares of Common Stock, equal to 4.0% of the total number of November Shares and November Pre-Funded Warrants sold in the November Offering, at an exercise price equal to $0.40, or 125% of the November Offering Price. The November Placement Agent Warrants are exercisable on the six-month anniversary of the issuance date and expire on the five-year anniversary of the commencement of the November Offering.

On March 20, 2026, the Company entered into the Purchase Agreement with the Selling Stockholders, pursuant to which we issued the Selling Stockholders in the Private Placement an aggregate of (i) 10,485 shares of Series A Preferred Stock, (ii) Series B Warrants to purchase up to 85,223,126 shares of Common Stock, or Series B Pre-Funded Warrants in lieu thereof, and (iii) Series C warrants to purchase up to 85,223,126 shares of Common Stock, or Series C Pre-Funded Warrants in lieu thereof. The purchase price per share of Series A Preferred Stock, Series B Warrant to 85,223,126 shares of Common Stock, or Series B Pre-Funded Warrants in lieu thereof, and Series C Warrant to 85,223,126 shares of Common Stock, or Series C Pre-Funded Warrants in lieu thereof was $1,000. Each Share of Series A Preferred stock is convertible into 8,128.1 Series A Conversion Shares, or Series A Preferred Pre-Funded Warrants to purchase Series A Preferred Pre-Funded Warrant Shares.

The Private Placement closed on March 20, 2026.

II-4

Subject to the terms and limitations contained in the Certificate of Designations, the Series A Preferred Stock is not convertible into Common Stock until the Stockholder Approval. Effective as of 5:00 p.m. Eastern Time on the first business day after the date of the Stockholder Approval and subject to the Company filing the Certificate of Amendment, each share of Series A Preferred Stock will automatically convert into approximately 8,128.1 Series A Conversion shares, subject to adjustment as provided in the Certificate of Designations and subject to the Series A Preferred Stock Beneficial Ownership Limitation.

The Series C Warrants will be exercisable following the receipt of Stockholder Approval and effectiveness of the Certificate of Amendment Filing, and will terminate 30 calendar days after the date the Company publicly announces data from its cosmetic filaggrin study in humans; provided, however, if the closing sale price of the Common Stock is below $0.123, the exercise price per Series C Exercise Share, then on the Series C Termination Date, the exercise price of the Series C Warrants shall automatically reset to the closing sale price of the Common Stock on such date (subject to a floor equal to 50% of the original exercise price of $0.123 per share), and the Series C Termination Date shall be extended by an additional 30 calendar days. If the closing sale price of the Common Stock is at or above the $0.123 exercise price on the Series C Termination Date, no extension shall apply.

The Pre-Funded Warrants have an exercise price of $0.0001 per share. Each Pre-Funded Warrant that may be issued in accordance with the Certificate of Designations and the Warrants will be exercisable immediately upon issuance and continuing through and including the date it is exercised in full.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

	(1)	To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

	i.	To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended, or the Securities Act;

	ii.	To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

	iii.	To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

	(2)	That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

	(3)	To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

	(4)	That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

	(5)	That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: (i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424; (ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; (iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and (iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

	(6)	The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
