PROSPECTUS

ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus are part of a “shelf” registration statement on Form S-3 (File No. 333-236735) that we filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 28, 2020, which was amended on March 13, 2020 and declared effective on March 19, 2020.

This document contains two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part, the accompanying prospectus dated March 19, 2020, including the documents incorporated by reference, provides more general information. Generally, when we refer to this prospectus, we are referring to both parts of this document combined. To the extent there is a conflict between the information contained in this prospectus supplement, on the one hand, and the information contained in the accompanying prospectus or in any document incorporated by reference that was filed with the SEC before the date of this prospectus supplement, on the other hand, you should rely on the information in this prospectus supplement. If any statement in one of these documents is inconsistent with a statement in another document having a later date - for example, a document incorporated by reference in the accompanying prospectus - the statement in the document having the later date modifies or supersedes the earlier statement. You should read this prospectus supplement and the accompanying prospectus, including the information incorporated by reference and any free writing prospectus that we have authorized for use in connection with this offering, in their entirety before making an investment decision.

You should rely only on the information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, along with the information contained in any free writing prospectus that we have authorized for use in connection with this offering.

THE OFFERING

RISK FACTORS

Investing in our common stock involves a high degree of risk. This prospectus supplement does not describe all of those risks. You should consider the risk factors described in this prospectus under the caption “Risks Related to This Offering and Our Securities” below, as well as the those described under the caption “Risk Factors” in the documents incorporated by reference herein, including our Annual Report on Form 10-K for the fiscal year ended June 30, 2019 filed with the SEC on August 26, 2019, together with the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, and in any free writing prospectus that we have authorized for use in connection with this offering, before making an investment decision.

If any of these risks occur, our business, financial condition, results of operations and future prospects would likely be materially and adversely affected. In these circumstances, the market price of our common stock would likely decline and you may lose all or part of your investment. Share information set forth in these risk factors is as of the dates set forth herein or therein and unless otherwise indicated, does not give effect to the issuance of the securities in connection with this offering.

Risks Related to this Offering and Our Securities

You will experience immediate and substantial dilution as a result of this offering. 

The offering price per share in this offering exceeds the net tangible book value per share of our common stock outstanding prior to this offering. Based on the sale of 1,000,000 shares of our common stock at the public offering price of $1.09 per share, for aggregate gross proceeds of approximately $1,090,000, and after deducting estimated aggregate offering expenses payable by us, you will experience immediate dilution of $0.99 per share, representing the difference between our as adjusted net tangible book value per share as of June 30, 2019 after giving effect to this offering and the offering price. In addition, we are not restricted from issuing additional securities in the future, including shares of common stock, securities that are convertible into or exchangeable for, or that represent the right to receive, common stock or substantially similar securities. The issuance of these securities may cause further dilution to our stockholders. The exercise of outstanding stock options and the vesting of outstanding restricted stock units may also result in further dilution of your investment. See the section entitled “Dilution” elsewhere in this prospectus supplement for a more detailed illustration of the dilution you may incur as a result of this offering. You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the price per share in this offering. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions may be higher or lower than the price per share paid by investors in this offering.

We do not currently intend to pay dividends on our common stock, and any return to investors is expected to come, if at all, only from potential increases in the price of our common stock.

At the present time, we intend to use available funds to finance our operations. Accordingly, while payments of dividends is within the discretion of our board of directors, no cash dividends on our common stock have been declared or paid by us, and we have no intention of paying any such dividends in the foreseeable future. Any return to investors is expected to come, if at all, only from potential increases in the price of our common stock.

Management will have broad discretion as to the use of the net proceeds from this offering, and we may not use the proceeds effectively.

Our management will have broad discretion as to the application of the net proceeds and could use them for purposes other than those contemplated at the time of this offering. Our stockholders may not agree with the manner in which our management chooses to allocate and spend the net proceeds. Moreover, our management may use the net proceeds for corporate purposes that may not increase our results of operations or the market value of our common stock. Our failure to apply these funds effectively could have a material adverse effect on our business, delay the development and approval of our products and cause the price of our common stock to decline.

We need additional funding to execute our business plan, which funding may not be available on commercially acceptable terms or at all. If we are unable to raise capital when needed, we may be forced to delay, reduce or eliminate the commercialization of our development and manufacturing services and efforts or our product development programs.

We have limited financial resources and need substantial additional funding in connection with our continuing operations, especially if we are delayed or are unsuccessful in attracting and maintaining customers for the development, manufacturing and technology transfer services offered by iBio CDMO. To the extent that we initiate or continue clinical development without securing collaborator or licensee funding, our research and development expenses could increase substantially. Additionally, to the extent that our efforts to out-license our technologies and product candidates are unsuccessful or we find that it is necessary to advance the development of product candidates further than contemplated by our current business plans to secure favorable licensing terms, we would require substantial additional capital.

When we elect to raise additional funds or additional funds are required, we may raise such funds from time to time through public or private equity offerings, debt financings, corporate collaboration and licensing arrangements or other financing alternatives, as well as through sales of common stock. Additional equity or debt financing or corporate collaboration and licensing arrangements may not be available on acceptable terms, if at all. If we are unable to raise capital in sufficient amounts when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or commercialization efforts and our ability to generate revenues and achieve or sustain profitability will be substantially harmed.

We expect our existing cash on hand as of May 13, 2020, in the amount of approximately $15.8 million, together with funds we may develop from future sales pursuant to the purchase agreement we entered into on March 19, 2020 with Lincoln Park, and proceeds realized in connection with license and collaboration arrangements and the operation of our subsidiary, iBio CDMO, will be sufficient to meet our projected operating requirements through June 30, 2021. Based on our projections, the Company plans to fund its future business operations using cash on hand, through proceeds from the sale of additional equity or other securities, and through proceeds realized in connection with the commercialization of its technologies and proprietary products, license and collaboration arrangements and the operation of iBio CDMO.

We have based this projection on assumptions that may prove to be wrong, in which case we may deplete our cash resources sooner than we currently anticipate. Our future capital requirements will depend on many factors, including:

If we are unsuccessful in raising additional capital or other alternative financing, we might have to defer or abandon our efforts to commercialize our intellectual property and decrease or even cease operations.

iBio is subject to compliance under the NYSE American continued listing standards as set forth in Section 1003(a)(ii) and Section 1003(a)(iii) of the NYSE American Company Guide.

On October 16, 2019, the Company received notice from NYSE American that it is currently is below NYSE American’s continued listing standards set forth in Section 1003(a)(ii) of the NYSE American Company Guide, which applies if a listed company has stockholders’ equity of less than $4,000,000 and has reported losses from continuing operations and/or net losses in three of its four most recent fiscal years, and Section 1003(a)(iii) of the NYSE American Company Guide, which applies if a listed company has stockholders’ equity of less than $6,000,000 and has reported losses from continuing operations and/or net losses in its five most recent fiscal years. NYSE American indicated that a review of the Company shows that the Company is below compliance with Section 1003(a)(ii) and Section 1003(a)(iii) because it reported stockholders’ equity of $2.46 million as of June 30, 2019 and net losses in its five most recent fiscal years ended June 30, 2019.

On December 9, 2019, the Company received a further notice from NYSE American that the Company currently is below NYSE American’s continued listing standards set forth in Section 1003(a)(i) of the NYSE American Company Guide, which applies if a listed company has stockholders’ equity of less than $2,000,000 and has reported losses from continuing operations and/or net losses in two of its three most recent fiscal years, as reported in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on December 13, 2019. 

On January 10, 2020, the Company received notice from NYSE American that NYSE Regulation has accepted the Company’s November 15, 2019 plan to regain compliance with the exchange’s continued listing standards set forth in Sections 1003(a)(i), 1003(a)(ii) and 1003(a)(iii) of the NYSE American Company Guide and has granted the Company through December 9, 2020, subject to periodic review by the exchange, including quarterly monitoring, to regain compliance with the initiatives outlined in the plan. If the Company is not in compliance with the continued listing standards by December 9, 2020, or if the Company does not make progress consistent with the plan during the plan period, the NYSE Regulation staff will initiate delisting proceedings as appropriate.

The Company expects revenues related to its CDMO core services offering, potential commercialization of its technologies and the potential development and eventual commercialization of proprietary pipeline products. The Company cannot be certain it will succeed in these activities and may never generate revenues that are significant or large enough to achieve profitability.

 iBio is subject to compliance under the NYSE American continued listing standards as set forth in Section 1003(f)(v) of the NYSE American Company Guide, related to securities selling price.

The Company is subject to NYSE American continued listing standards, pursuant to Section 1003(f)(v) of the Company Guide, whereby the Company’s continued listing is impacted by iBio, Inc.’s securities selling for a low price per share for a substantial period of time.

The December 9, 2019 notification from NYSE American described above under “Risk Factors - iBio is subject to compliance under the NYSE American continued listing standards as set forth in Section 1003(a)(ii) and Section 1003(a)(iii) of the NYSE American Company Guide” also stated that NYSE American has determined that the Company’s securities have been selling for a low price per share for a substantial period of time and pursuant to Section 1003(f)(v) of the NYSE American Company Guide, the Company’s continued listing on the exchange is predicated on the Company effecting a reverse stock split or otherwise demonstrating sustained improvement in its share price within a reasonable period of time, which the exchange has determined to be no later than June 9, 2020.

The sale of our common stock through current or future equity offerings may cause dilution and could cause the price of our common stock to decline.

We are entitled under our certificate of incorporation to issue up to 275 million shares of common stock, par value $.001 per share, and 1 million shares of preferred stock.

On November 30, 2017, the Company closed a public offering of 2,250,000 shares of its common stock at a public offering price of $2.00 per share raising gross proceeds of $4,500,000. The shares of common stock were issued pursuant to an underwriting agreement entered into between the Company and Aegis Capital Corp. (“Aegis”). The Company paid Aegis a discount of 7% to the public offering price with respect to shares purchased in the offering by investors who did not have a pre-existing relationship with the Company prior to the offering (the “New Investors”), and a discount of 3.5% to the public offering price with respect to shares purchased in the offering by investors who did have a pre-existing relationship with the Company. In addition to the underwriting discounts, the Company issued to Aegis 11,000 shares of its common stock, equal to 2% of the aggregate shares of common stock sold in the offering to the New Investors. The Company incurred underwriting discounts, commissions and other offering expenses of $311,000 related to closing and completion of this public offering.

On June 26, 2018, the Company closed on an underwritten public offering with total gross proceeds of approximately $16,000,000, before deducting underwriting discounts, commissions and other offering expenses payable by the Company. The securities offered by the Company consisted of (i) 4,350,000 shares of common stock at $0.90 per share, (ii) 6,300 shares of Series A Preferred Stock, with a stated value of $1,000 per preferred share, and convertible into an aggregate of 7,000,000 shares of common stock at $0.90 per share, (iii) 5,785 shares of Series B Preferred Stock, with a stated value of $1,000 per preferred share, and convertible into an aggregate of 6,427,778 shares of common stock at $0.90 per share. The Company granted the underwriters A.G.P./Alliance Global Partners, a 45-day option to purchase up to an additional 2,666,666 shares of common stock to cover over-allotments, if any. On July 12, 2018, the Company received approximately $1,350,000, before deducting underwriting discounts, commissions and other offering expenses payable by the Company, from the proceeds of the sale of 1,500,000 over-allotment shares of common stock purchased at $0.90 by the underwriter during the 45-day provision.

On October 29, 2019, the Company closed a public offering of (i) 2,450,000 shares of the Company’s common stock, (ii) 4,510 shares of the Company’s Series C Convertible Preferred Stock, (iii) 25,000,000 Series A warrants to purchase shares of the Company’s Common Stock and (iv) 25,000,000 Series B warrants to purchase shares of the Company’s Common Stock. The net proceeds to the Company from the sale of the Shares, Series C Preferred Shares, and Warrants was approximately $4.52 million, after deducting underwriting discounts and commissions and other offering expenses payable by the Company.

On March 19, 2020, we entered into a purchase agreement with Lincoln Park, pursuant to which we have the right to sell to Lincoln Park up to an aggregate of $50,000,000 in shares of our Common Stock over the 36-month term of the purchase agreement, subject to certain limitations and conditions set forth in the purchase agreement. As of May 13, 2020, we have sold 15.0 million shares of Common Stock for gross proceeds of approximately $15.7 million pursuant to this facility.

As of May 13, 2020, we had issued and outstanding approximately 117,360,032 shares of common stock, one share of iBio CMO Preferred Tracking Stock, no shares of Series A Preferred, 5,785 shares of Series B Preferred and no shares of Series C Preferred. As of May 13, 2020, 2.2 million options to purchase shares of common stock were outstanding, 41,150 shares of common stock were issuable upon exercise of restricted stock units and we had approximately 4.3 million shares of common stock reserved for future issuance of additional equity grants under our 2018 Omnibus Equity Incentive Plan, as amended.

In addition, we had approximately 28,925,000 shares of common stock reserved for future possible conversions of the Series B Preferred. Accordingly, we will be able to issue up to approximately 122 million additional shares of common stock and 994,214 shares of preferred stock. Sales of our common stock offered through current or future equity offerings may result in substantial dilution to our stockholders. Sales of our common stock offered through current or future equity offerings may result in substantial dilution to our stockholders. The sale of a substantial number of shares of our common stock to investors, or anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales.

Our business and share price may be adversely affected by the COVID-19 pandemic.

The outbreak of the coronavirus disease 2019 (COVID-19) in China and its spread and continued progress in various countries around the world, including the United States, has led authorities around the globe to take various extraordinary measures to stem the spread of the disease, such as emergency travel and transportation restrictions, school closures, quarantines and social distancing measures. The outbreak of COVID-19 has had an adverse effect on global markets and may lead to a major slowdown in the economy in the United States and globally.

On March 11, 2020, iBio filed four provisional patent applications (the “Patent Applications”) that apply its Virus Like Particle [VLP] platform technology, or its lichenase carrier immunostimulatory (“LickM”) adjuvant technology, in conjunction with its FastPharming™ Manufacturing System for treating or preventing infections with the SARS-CoV-2 virus, which is the agent that causes COVID-19.

In addition, as previously announced, on February 6, 2020, the Company and Beijing CC-Pharming Ltd. (“BCCP”) executed a Statement of Work 2 (“SOW2”), pursuant to an existing Master Joint Development Agreement between iBio and BCCP, memorializing their collaborative efforts to develop and test a new BCCP 2019-nCoV vaccine to be manufactured using iBio’s FastPharming System™.

The contemplated collaborative effort with BCCP is still in early stages and has not yet progressed in any material respect. There is no assurance that the contemplated collaboration with BCCP or the Company’s separate activities relating to the development of intellectual property in the field of vaccine candidate development for the SARS-CoV-2 virus, which are reflected in the filing of the Patent Applications described above, will result in the development of any successful product candidates or generate any proceeds to the Company. These efforts are subject to the risks relating to the development and commercialization of our technologies and product candidates, risks relating to our intellectual property and other risks relating to our operations described in our Annual Report on Form 10-K for the year ended June 30, 2019, which are incorporated herein by reference.

In addition, we may face additional risks relating to the COVID-19 pandemic and its potential negative effects on our operations, share price and the world economy generally. The rapidly evolving nature of the circumstances is such that it is impossible, at this stage, to determine the full and overall impact the COVID-19 pandemic may have, but it could disrupt production and cause delays in the supply and delivery of products used in our operations, adversely affect our employees and disrupt our operations and manufacturing activities, all of which may have a material adverse effect on our business.

On April 16, 2020, we received $600,000 related to our filing under the Paycheck Protection Program and Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). Forgiveness of this loan is only available for principal that is used for the limited purposes that qualify for forgiveness under the Small Business Administration’s requirements, and that to obtain forgiveness, we must request it and must provide documentation in accordance with Small Business Administration requirements, and certify that the amounts we are requesting to be forgiven qualify under those requirements. Forgiveness of the loan is dependent upon approval of the Small Business Administration and there can be no assurance or certainty that forgiveness will in fact occur.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement, accompanying prospectus and the documents incorporated by reference herein or therein contain or incorporate by reference forward-looking statements that involve risks and uncertainties. These forward-looking statements are not historical facts but rather are plans and predictions based on current expectations, estimates and projections about our industry, our beliefs and assumptions. We use words such as “anticipate,” “expect,” “intend,” “plan,” “believe,” “seek,” “estimate” and variations of these words and similar expressions to identify forward-looking statements. These statements are not guarantees of future performance and are subject to certain risks, uncertainties and other factors, some of which are beyond our control, are difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements. These risks and uncertainties include those described in the section above entitled “Risk Factors.” You should not place undue reliance on these forward-looking statements, which reflect our view only as of the date of this prospectus.

USE OF PROCEEDS

We currently intend to use the net proceeds of this offering for working capital and general corporate purposes. We may invest a portion of the proceeds in iBio CDMO to be used by iBio CDMO for its working capital and general corporate purposes. As of the date of this prospectus supplement and except as explicitly set forth herein, we cannot specify with certainty all of the particular uses of the proceeds from this offering. Accordingly, we will retain broad discretion over the use of such proceeds. Pending use of the net proceeds of this offering as described above, we intend to invest the net proceeds in short-term interest-bearing investment grade instruments.

These expected uses of proceeds represent our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve. The amounts and timing of our actual expenditures may vary significantly depending on numerous factors, including those described in “Special Note Regarding Forward-Looking Statements” above. As a result, our management will have broad discretion in the application of the net proceeds from this offering, and investors will be relying on the judgment of our management regarding the application of the net proceeds from this offering. The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business.

We have not specifically identified the precise amounts we will spend on each of these areas or the timing of these expenditures. The amounts actually expended for each purpose may vary significantly depending upon numerous factors, including the amount and timing of the proceeds from this offering and our operating expenses. In addition, expenditures may also depend on the establishment of new collaborative arrangements with other companies, the availability of other financing, and other factors.

We will be required to raise substantial additional capital to continue to fund our continued activities. We may raise additional capital through additional public or private financings, as well as collaborative relationships, incurring debt and other available sources. Please see the discussion of the risks associated with our liquidity under the caption “Risk Factors” included in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended June 30, 2019, which is incorporated by reference in this prospectus.

DILUTION

If you purchase shares of our common stock in this offering, your interest will be diluted immediately to the extent of the difference between the public offering price per share and the net tangible book value per share of our common stock immediately after this offering.

Our historical net tangible book deficit as of June 30, 2019 was $1,083,000, or $0.05 per share of our common stock. Historical net tangible book deficit per share represents the amount of our total tangible assets less total liabilities, divided by the number of shares of our common stock outstanding as of June 30, 2019.

After giving effect to the sale of shares of our common stock in this offering at a price of $1.09 per share and after deducting estimated offering expenses payable by us, the as adjusted net tangible book value as of June 30, 2019 would have been $2,148,000 million, or $0.10 per share. This represents an immediate increase in the as adjusted net tangible book value to existing stockholders of $0.05 per share and an immediate decrease to new investors purchasing common stock in this offering of $0.99 per share, as illustrated by the following table:

The number of shares of common stock shown above to be outstanding after this offering is based on 117,360,032 shares as of May 13, 2020 and 20,152,458 shares as of June 30, 2019, and excludes:

To the extent that options or warrants are exercised, new options or other equity awards are issued under our 2018 Omnibus Equity Incentive Plan, or we issue additional shares of common stock in the future, there may be further dilution to investors participating in this offering. In addition, we may choose to raise additional capital because of market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. If we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

PLAN OF DISTRIBUTION

We have entered into the Purchase Agreement with Lincoln Park on May 13, 2020, which provides that we will sell 1,000,000 shares of our Common Stock to Lincoln Park at a price of $1.09 per share, for an aggregate purchase price of $1,090,000, pursuant to this prospectus supplement and the accompanying base prospectus.

We will pay all of the expenses incident to the registration, offering and sale of our shares of Common Stock under this prospectus supplement and the accompanying base prospectus. We estimate that the total expenses for the offering will be approximately $25,000.

Lincoln Park represented to us that at no time prior to the date of the Purchase Agreement has Lincoln Park or its agents, representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any short sale (as such term is defined in Rule 200 of Regulation SHO of the Securities Exchange Act of 1934, as amended, or the Exchange Act) of our Common Stock or any hedging transaction.

We have agreed to indemnify Lincoln Park and certain other persons against certain liabilities in connection with this offering of our shares of Common Stock, including liabilities arising under the Securities Act and the Exchange Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities.

Lincoln Park may be deemed to be an “underwriter” within the meaning of the Securities Act.

The transfer agent and registrar for our Common Stock is Continental Stock Transfer and Trust Company.

Business Overview

iBio’s principal current business is to operate a full-service plant-based expression biologics contract development and manufacturing organization (“CDMO”) through its subsidiary, iBio CDMO LLC. iBio’s FastPharming^TM expression system, iBio’s proprietary approach to plant-made pharmaceutical (“PMP”) production, can produce a range of recombinant products including monoclonal antibodies, antigens for subunit vaccine design, lysosomal enzymes, virus-like particles (“VLP”), blood factors and cytokines, scaffolds, maturogens and materials for 3D bio-printing and bio-fabrication, biopharmaceutical intermediates and others, as well as create and produce proprietary derivatives of pre-existing products with improved properties. iBio utilizes its proprietary technologies and production facilities to provide product development and manufacturing services to clients, collaborators and third-party customers as well as developing its own product candidates.

iBio’s FastPharming™ platform includes transient transfection of plants and the use of transgenic plants for biologics development and manufacturing, as well as glycan engineering tools, and offers many benefits over the limitations of other expression systems, including:

iBio CDMO services consist of the following core offerings:

iBio was established as a public company in August 2008 as the result of a spinoff from Integrated BioPharma, Inc. and operates in one business segment under the direction of its Executive Chairman. iBio’s wholly-owned and majority-owned subsidiaries (the “Company”) are as follows:

iBio CDMO LLC (“iBio CDMO”) (originally named iBio CMO LLC) – iBio CDMO is a Delaware limited liability company formed on December 16, 2015 as iBio CMO, LLC to develop and manufacture plant-made pharmaceuticals and provide related services to clients. Effective July 1, 2017, iBio CMO changed its name to iBio CDMO. As of December 31, 2015, the Company owned 100% of iBio CDMO. On January 13, 2016, the Company entered into a contract manufacturing joint venture with an affiliate of Eastern Capital Limited (“Eastern”), a stockholder of the Company (the “Eastern Affiliate”). The Eastern Affiliate contributed $15 million in cash for a 30% interest in iBio CDMO. The Company retained a 70% interest in iBio CDMO and contributed a royalty-bearing license which grants iBio CDMO a non-exclusive license to use the Company’s proprietary technologies for research purposes and an exclusive U.S. license for manufacturing purposes. The Company retained the exclusive right to grant product licenses to those who wish to sell or distribute products made using the Company’s technologies.

On February 23, 2017, the Company entered into an exchange agreement with the Eastern Affiliate, pursuant to which the Company acquired substantially all of the interest in iBio CDMO held by the Eastern Affiliate in exchange for one share of the Company’s iBio CMO Preferred Tracking Stock, par value $0.001 per share (the “Preferred Tracking Stock”). After giving effect to the transaction, the Company owns 99.99% of iBio CDMO. See Note 10 for a further discussion.

iBio CDMO’s operations take place in Bryan, Texas in a facility controlled by another affiliate of Eastern (the “Second Eastern Affiliate”) as sublandlord. The facility is a 139,000-square foot Class A life sciences building located on land owned by the Texas A&M system, designed and equipped for plant-made manufacture of biopharmaceuticals. The Second Eastern Affiliate granted iBio CDMO a 34-year lease (the "Sublease") for the facility as well as certain equipment (see Note 9). iBio CDMO commenced commercial operations in January 2016. iBio CDMO expects to operate on the basis of three parallel lines of business: (1) Development and manufacturing of third-party products; (2) Development and production of iBio’s proprietary product(s) for treatment of fibrotic diseases and/or other proprietary iBio products; and (3) Commercial technology transfer services including facility design, as needed.

iBIO DO BRASIL BIOFARMACÊUTICA LTDA (“iBio Brazil”) – iBio Brazil is a subsidiary organized in Brazil in which the Company has a 99% interest. iBio Brazil was formed to manage and expand the Company’s business activities in Brazil. The activities of iBio Brazil are intended to include coordination and expansion of the Company’s existing relationship with Fundacao Oswaldo Cruz/Fiocruz (“Fiocruz”) beyond the Yellow Fever Vaccine program (see Note 7) and development of additional products with private sector participants for the Brazilian market. iBio Brazil commenced operations during the first quarter of the fiscal year ended June 30, 2015.

FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated herein by reference contain forward-looking statements that involve risks and uncertainties. These forward-looking statements are not historical facts but rather are plans and predictions based on current expectations, estimates and projections about our industry, our beliefs and assumptions. Discussions containing these forward-looking statements may be found, among other places, in the Sections entitled “Business Overview,” “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” incorporated by reference from our most recent Annual Report on Form 10-K and in our Quarterly Reports on Form 10-Q, as well as any amendments thereto, filed with the SEC.

We use words such as “anticipate,” “expect,” “intend,” “plan,” “believe,” “seek,” “estimate” and variations of these words and similar expressions to identify forward-looking statements. These statements are not guarantees of future performance and are subject to certain risks, uncertainties and other factors, some of which are beyond our control, are difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements. These risks and uncertainties include those described in the section above entitled “Risk Factors.” You should not place undue reliance on these forward-looking statements, which reflect our view only as of the date of this prospectus.

Except as required by law, we assume no obligation to update these forward-looking statements publicly, or to revise any forward-looking statements to reflect events or developments occurring after the date of this prospectus, even if new information becomes available in the future.

USE OF PROCEEDS

We cannot guarantee that we will receive any proceeds in connection with this offering because we may be unable or choose not to issue and sell any securities covered by this prospectus.

Unless otherwise provided in a supplement or amendment to this prospectus, we intend to use any net proceeds from this offering, together with other available funds, for operating costs, including working capital needs and for other general corporate purposes.

We have not specifically identified the precise amounts we will spend on each of these areas or the timing of these expenditures. The amounts actually expended for each purpose may vary significantly depending upon numerous factors, including the amount and timing of the proceeds from this offering and our operating expenses. In addition, expenditures may also depend on the establishment of new collaborative arrangements with other companies, the availability of other financing, and other factors.

We will be required to raise substantial additional capital to continue to fund our continued activities. We may raise additional capital through additional public or private financings, as well as collaborative relationships, incurring debt and other available sources.

PLAN OF DISTRIBUTION

The securities being offered may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market prices, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected at various times in one or more of the following transactions, or in other kinds of transactions:

We may sell our securities directly to one or more purchasers, or to or through underwriters, dealers or agents or through a combination of those methods. The related prospectus supplement will set forth the terms of each offering, including:

In addition, any securities covered by this prospectus that qualify for sale pursuant to Regulation S may be sold pursuant to Regulation S rather than pursuant to this prospectus.

In connection with the sale of our securities, underwriters may receive compensation from us or from purchasers of our securities in the form of discounts, concessions or commissions. Underwriters, dealers and agents that participate in the distribution of our securities may be deemed to be underwriters. Discounts or commissions they receive and any profit on their resale of our securities may be considered underwriting discounts and commissions under the Securities Act.

We may agree to indemnify underwriters, dealers and agents who participate in the distribution of our securities against various liabilities, including liabilities under the Securities Act. We may also agree to contribute to payments that the underwriters, dealers or agents may be required to make in respect of these liabilities. We may authorize dealers or other persons who act as our agents to solicit offers by various institutions to purchase our securities from us under contracts that provide for payment and delivery on a future date. We may enter into these contracts with commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others. If we enter into these agreements concerning any series of our securities, we will indicate that in the prospectus supplement or amendment.

In connection with an offering of our securities, underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of our securities. Specifically, underwriters may over-allot in connection with the offering, creating a syndicate short position in our securities for their own account. In addition, underwriters may bid for, and purchase, our securities in the open market to cover short positions or to stabilize the price of our securities. Finally, underwriters may reclaim selling concessions allowed for distributing our securities in the offering if the underwriters repurchase previously distributed securities in transactions to cover short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of our securities above independent market levels. Underwriters are not required to engage in any of these activities and may end any of these activities at any time. Agents and underwriters may engage in transactions with, or perform services for, us and our affiliates in the ordinary course of business.

DESCRIPTION OF SECURITIES we may offer

The descriptions of the securities contained in this prospectus, together with the applicable prospectus supplements, summarize all the material terms and provisions of the various types of securities that we may offer. We will describe in the applicable prospectus supplement the particular terms of the securities offered by that prospectus supplement. If we so indicate in the applicable prospectus supplement, the terms of the securities may differ from the terms we have summarized below. We will also include in the prospectus supplement information, where applicable, about material United States federal income tax considerations relating to the securities and the securities exchange, if any, on which the securities will be listed.

Description of Capital Stock

We are authorized to issue 275,000,000 shares of common stock, par value $.001 per share, and 1,000,000 shares of preferred stock, par value $.001 per share. Provisions of our certificate of incorporation, as amended, our first amended and restated bylaws and provisions of applicable Delaware law may discourage, delay or prevent a merger or other change in control that a stockholder may consider favorable. Pursuant to our certificate of incorporation, as amended, our Board of Directors may issue additional shares of common or preferred stock. Any additional issuance of common stock could have the effect of impeding or discouraging the acquisition of control of us by means of a merger, tender offer, proxy contest or otherwise, including a transaction in which our stockholders would receive a premium over the market price for their shares, and thereby protect the continuity of our management. Specifically, if in the due exercise of its fiduciary obligations, the Board of Directors were to determine that a takeover proposal was not in our best interest, shares could be issued by our Board of Directors without stockholder approval in one or more transactions that might prevent or render more difficult or costly the completion of the takeover by: 

Our certificate of incorporation, as amended, also allows our Board of Directors to fix the number of directors in our bylaws. Cumulative voting in the election of directors is specifically denied in our certificate of incorporation, as amended. The effect of these provisions may be to delay or prevent a tender offer or takeover attempt that a stockholder may determine to be in his, her or its best interest, including attempts that might result in a premium over the market price for the shares held by the stockholders.

Common Stock

Holders of common stock are entitled to one vote per share on all matters to be voted upon by the stockholders and are not entitled to cumulative voting for the election of directors. Holders of common stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by the Board of Directors out of funds legally available therefor subject to the rights of preferred stockholders. We do not intend to pay any cash dividends to the holders of common stock and anticipate reinvesting our earnings. In the event of liquidation, dissolution or winding up of our company, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities and the preferences of preferred stockholders. Shares of common stock have no preemptive, conversion or other subscription rights. There are no redemption or sinking fund provisions applicable to common stock.

Preferred Stock

Our Board is authorized to issue up to 1,000,000 shares of preferred stock in one or more series without stockholder approval. Our Board may determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.

The purpose of authorizing our Board to issue preferred stock in one or more series and determine the number of shares in the series and its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. Examples of rights and preferences that the Board may fix are:

The issuance of preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could make it more difficult for a third party to acquire, or could discourage a third party from acquiring, a majority of our outstanding voting stock. The rights of holders of our common stock described above, will be subject to, and may be adversely affected by, the rights of any preferred stock that we may designate and issue in the future.

We will incorporate by reference as an exhibit to the registration statement, which includes this prospectus, the form of any certificate of designation that describes the terms of the series of preferred stock we are offering. This description and the applicable prospectus supplement will include:

When we issue shares of preferred stock under this prospectus, the shares will fully be paid and nonassessable and will not have, or be subject to, any preemptive or similar rights.

Description of Warrants

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the warrants that we may offer under this prospectus and the related warrant agreements and warrant certificates. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any warrants offered under that prospectus supplement may differ from the terms described below. Specific warrant agreements will contain additional important terms and provisions and will be incorporated by reference as an exhibit to the registration statement, which includes this prospectus.

General

We may issue warrants for the purchase of common stock and/or preferred stock in one or more series. We may issue warrants independently or together with common stock and/or preferred stock, and the warrants may be attached to or separate from these securities.

We will evidence each series of warrants by warrant certificates that we will issue under a separate warrant agreement. We will enter into the warrant agreement with a warrant agent. We will indicate the name and address of the warrant agent in the applicable prospectus supplement relating to a particular series of warrants.

We will describe in the applicable prospectus supplement the terms of the series of warrants, including:

Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including, in the case of warrants to purchase common stock or preferred stock, the right to receive any dividends or payments upon our liquidation, dissolution or winding up or to exercise any voting rights.

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to 5:00 P.M. New York time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Holders of the warrants may exercise the warrants by delivering the warrant certificate representing the warrants to be exercised together with specified information, and paying the required amount to the warrant agent in immediately available funds, as provided in the applicable prospectus supplement. We will set forth on the reverse side of the warrant certificate and in the applicable prospectus supplement the information that the holder of the warrant will be required to deliver to the warrant agent upon exercise.

Upon receipt of the required payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by the warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

Enforceability of Rights By Holders of Warrants

Each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue or series of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, its warrants.

Description of Units

We may issue units comprised of shares of common stock, shares of preferred stock and warrants in any combination. We may issue units in such amounts and in as many distinct series as we wish. This section outlines certain provisions of the units that we may issue. If we issue units, they will be issued under one or more unit agreements to be entered into between us and a bank or other financial institution, as unit agent. The information described in this section may not be complete in all respects and is qualified entirely by reference to the unit agreement with respect to the units of any particular series. The specific terms of any series of units offered will be described in the applicable prospectus supplement. If so described in a particular supplement, the specific terms of any series of units may differ from the general description of terms presented below. We urge you to read any prospectus supplement related to any series of units we may offer, as well as the complete unit agreement and unit certificate that contain the terms of the units. If we issue units, forms of unit agreements and unit certificates relating to such units will be incorporated by reference as exhibits to the registration statement, which includes this prospectus.

Each unit that we may issue will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date. The applicable prospectus supplement may describe:

The provisions described in this section, as well as those described under “Description of Capital Stock,” and “Description of Warrants” will apply to the securities included in each unit, to the extent relevant and as may be updated in any prospectus supplements.

Issuance in Series

We may issue units in such amounts and in as many distinct series as we wish. This section summarizes terms of the units that apply generally to all series. Most of the financial and other specific terms of your series will be described in the applicable prospectus supplement.

Unit Agreements

We will issue the units under one or more unit agreements to be entered into between us and a bank or other financial institution, as unit agent. We may add, replace or terminate unit agents from time to time. We will identify the unit agreement under which each series of units will be issued and the unit agent under that agreement in the applicable prospectus supplement.

The following provisions will generally apply to all unit agreements unless otherwise stated in the applicable prospectus supplement.

Modification without Consent

We and the applicable unit agent may amend any unit or unit agreement without the consent of any holder:

We do not need any approval to make changes that affect only units to be issued after the changes take effect. We may also make changes that do not adversely affect a particular unit in any material respect, even if they adversely affect other units in a material respect. In those cases, we do not need to obtain the approval of the holder of the unaffected unit; we need only obtain any required approvals from the holders of the affected units.

Modification with Consent

We may not amend any particular unit or a unit agreement with respect to any particular unit unless we obtain the consent of the holder of that unit, if the amendment would:

Any other change to a particular unit agreement and the units issued under that agreement would require the following approval:

These provisions regarding changes with majority approval also apply to changes affecting any securities issued under a unit agreement, as the governing document.

In each case, the required approval must be given by written consent.

Unit Agreements Will Not Be Qualified under Trust Indenture Act

No unit agreement will be qualified as an indenture, and no unit agent will be required to qualify as a trustee, under the Trust Indenture Act. Therefore, holders of units issued under unit agreements will not have the protections of the Trust Indenture Act with respect to their units.

Mergers and Similar Transactions Permitted; No Restrictive Covenants or Events of Default

The unit agreements will not restrict our ability to merge or consolidate with, or sell our assets to, another corporation or other entity or to engage in any other transactions. If at any time we merge or consolidate with, or sell our assets substantially as an entirety to, another corporation or other entity, the successor entity will succeed to and assume our obligations under the unit agreements. We will then be relieved of any further obligation under these agreements.

The unit agreements will not include any restrictions on our ability to put liens on our assets, including our interests in our subsidiaries, nor will they restrict our ability to sell our assets. The unit agreements also will not provide for any events of default or remedies upon the occurrence of any events of default.

Governing Law

The unit agreements and the units will be governed by Delaware law.

Form, Exchange and Transfer

We will issue each unit in global—i.e., book-entry—form only. Units in book-entry form will be represented by a global security registered in the name of a depositary, which will be the holder of all the units represented by the global security. Those who own beneficial interests in a unit will do so through participants in the depositary’s system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depositary and its participants. We will describe book-entry securities, and other terms regarding the issuance and registration of the units in the applicable prospectus supplement.

Each unit and all securities comprising the unit will be issued in the same form.

If we issue any units in registered, non-global form, the following will apply to them.

The units will be issued in the denominations stated in the applicable prospectus supplement. Holders may exchange their units for units of smaller denominations or combined into fewer units of larger denominations, as long as the total amount is not changed.

Holders may exchange or transfer their units at the office of the unit agent. Holders may also replace lost, stolen, destroyed or mutilated units at that office. We may appoint another entity to perform these functions or perform them ourselves.

Holders will not be required to pay a service charge to transfer or exchange their units, but they may be required to pay for any tax or other governmental charge associated with the transfer or exchange. The transfer or exchange, and any replacement, will be made only if our transfer agent is satisfied with the holder’s proof of legal ownership. The transfer agent may also require an indemnity before replacing any units.

If we have the right to redeem, accelerate or settle any units before their maturity, and we exercise our right as to less than all those units or other securities, we may block the exchange or transfer of those units during the period beginning 15 days before the day we mail the notice of exercise and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers of or exchange any unit selected for early settlement, except that we will continue to permit transfers and exchanges of the unsettled portion of any unit being partially settled. We may also block the transfer or exchange of any unit in this manner if the unit includes securities that are or may be selected for early settlement.

Only the depositary will be entitled to transfer or exchange a unit in global form, since it will be the sole holder of the unit.

Payments and Notices

In making payments and giving notices with respect to our units, we will follow the procedures as described in the applicable prospectus supplement.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Our Certificate of Incorporation provides for indemnification of our officers and directors to the extent permitted by Delaware law, which generally permits indemnification for actions taken by officers or directors as our representatives if the officer or director acted in good faith and in a manner he or she reasonably believed to be in the best interest of the corporation.

As permitted under Delaware law, our By-laws contain a provision indemnifying directors against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by them in connection with an action, suit or proceeding if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of our company, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful.

The separation and distribution agreement that we have entered into with Integrated BioPharma provides for indemnification by us of Integrated BioPharma and its directors, officers and employees for some liabilities, including liabilities under the Securities Act and the Securities Exchange Act of 1934 in connection with the distribution, and a mutual indemnification of each other for product liability claims arising from their respective businesses, and also requires that we indemnify Integrated BioPharma for various liabilities of iBio, and for any tax that may be imposed with respect to the distribution and which result from our actions or omissions in that regard.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

LEGAL MATTERS

The legality of the securities offered hereby has been passed on for us by Andrew Abramowitz, PLLC, New York, New York.
