5,555,556 Shares

Common Stock

6,000 Shares of Series A Convertible Preferred Stock

6,000 Shares of Series B Convertible Preferred Stock

We are offering up to 5,555,556 of shares (the “Shares”) of common stock, $0.001 par value, of iBio, Inc., a Delaware corporation (the “Company”) in a firm commitment underwritten public offering. Our common stock is traded on the exchange market of NYSE American LLC (the “NYSE American”) under the symbol “IBIO.”

We are also offering shares of our newly designated Series A Convertible Preferred Stock, $0.001 par value (the “Series A Preferred Stock”), which such offered shares of Series A Preferred Stock we refer to in this prospectus as “Series A Preferred Shares”, which will have a stated value of $1,000 and will be convertible into shares of our common stock at the public offering price of the Shares in this offering at the option of the holder, provided that as a result of such conversion, the holder, together with its affiliates, would not own more than 4.99% of the total number of shares of our common stock issued and outstanding at the time of conversion. Any holder may increase or decrease such percentage to any other percentage not in excess of 9.99% (the “Series A Maximum Conversion Limit”), provided that any increase in such percentage shall not be effective until 61 days after such notice to us. The Series A Preferred Shares do not generally have any voting rights unless and until converted into shares of common stock.

In addition, we are offering shares of our newly designated Series B Convertible Preferred Stock, $0.001 par value (the “Series B Preferred Stock”), which such offered shares of Series B Preferred Stock we refer to in this prospectus as “Series B Preferred Shares”, which will have a stated value of $1,000 and will be convertible into shares of our common stock at the public offering price of the Shares in this offering at the option of the holder, provided that as a result of such conversion, the holder, together with its affiliates, would not own more than 48% of the total number of shares of our common stock issued and outstanding at the time of conversion. The Series B Preferred Shares do not generally have any voting rights unless and until converted into shares of common stock.

The number of shares of our common stock outstanding after this offering will fluctuate depending on how many Series A Preferred Shares and Series B Preferred Shares are sold in this offering and whether and to what extent holders of Series A Preferred Shares and Series B Preferred Shares convert their shares to common stock.

On June 19, 2018, the last reported sale price of our common stock as reported on the NYSE American was $1.08 per share. The actual offering price per Share, per Series A Preferred Share and per Series B Preferred Share in this offering will be as determined between us and A.G.P./Alliance Global Partners (the “Underwriter”) at the time of pricing, and may be at a discount to the current market price of our common stock.

Assuming an offering price of $1.08 per Share, the Series A Preferred Shares will be convertible into an aggregate total of 5,555,556 shares of common stock and the Series B Preferred Shares will be convertible into an aggregate total of 5,555,556 shares of common stock.

There is no established trading market for the Series A Preferred Shares or Series B Preferred Shares, and we do not expect an active trading market to develop. We do not intend to list the Series A Preferred Shares or Series B Preferred Shares on any securities exchange or other trading market. Without an active trading market, the liquidity of the Series A Preferred Shares and Series B Preferred Shares will be limited.

RISK FACTORS

Our business faces many risks. Past experience may not be indicative of future performance, and as noted elsewhere in this prospectus, we have included forward-looking statements about our business, plans and prospects that are subject to change. You should carefully consider the risks described below, as well as those risks described in the sections titled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” each contained in our most recent Annual Report on Form 10-K for the year ended June 30, 2017 and our Quarterly Report on Form 10-Q for the quarterly period ended December 31, 2017, which have been filed with the SEC and are incorporated herein by reference in their entirety, as well as other information in this prospectus or in any other documents incorporated by reference. Each of the risks described in these sections and documents could adversely affect our business, financial condition, results of operations and prospects, and could result in a complete loss of your investment. This prospectus and the incorporated documents also contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks mentioned above. In addition to the other risks or uncertainties contained in this prospectus, the risks described below may affect our operating results, financial condition and cash flows. If any of these risks occur, either alone or in combination with other factors, our business, financial condition or operating results could be adversely affected and the trading price of common stock may decline. Moreover, readers should note this is not an exhaustive list of the risks we face; some risks are unknown or not quantifiable, and other risks that we currently perceive as immaterial may ultimately prove more significant than expected. Statements about plans, predictions or expectations should not be construed to be assurances of performance or promises to take a given course of action.

Risks Related to Our Financial Position and Need for Additional Capital

We have incurred significant losses since our inception. We expect to incur losses during our next fiscal year and may never achieve or maintain profitability.

Since our 2008 spinoff from Integrated BioPharma, Inc., we have incurred operating losses and negative cash flows from operations. Our net loss was approximately $16.1 million for the year ended June 30, 2017 and approximately $10.7 million for the year ended June 30, 2016. For the six months ended December 31, 2017, our net loss was approximately $7.7 million. As of December 31, 2017, we had an accumulated deficit of approximately $79.8 million.

To date, we have financed our operations primarily through the sale of common stock and warrants. We have devoted substantially all of our efforts to research and development, including the development and validation of our technologies, our CDMO facilities, and the development of a proprietary therapeutic product against fibrosis based upon our platform. We have not completed development of or commercialized any vaccine or therapeutic product candidates. We expect to continue to incur significant expenses and operating losses for at least the next fiscal year. We anticipate that our expenses and losses may increase substantially if we:

To become and remain profitable, we must succeed in commercializing our technology platforms or we, alone or with our licensees, must succeed in developing and eventually commercializing products that generate significant revenue. In addition, our profitability will depend on continuing to attract and maintain customers for the development, manufacturing and technology transfer services offered by our subsidiary iBio CDMO.

This will require us, alone or with our licensees and collaborators, to be successful in a range of challenging activities, including completing preclinical testing and clinical trials of our product candidates, obtaining regulatory approval for these product candidates and manufacturing, marketing and selling those products for which regulatory approval is obtained or establishing collaborations with parties willing and able to provide necessary capital or other value. We may never succeed in these activities. Our profitability also will depend on spending on iBio CDMO’s services by its customers and potential customers. We may never generate revenues that are significant or large enough to achieve profitability.

Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would diminish the value of our company and could impair our ability to raise capital, expand our business, diversify our product offerings or continue our operations. A decline in the value of our company could also cause you to lose all or part of your investment.

We will need substantial 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 would be forced to delay, reduce or eliminate our product development programs or commercialization efforts.

We have limited financial resources and will need substantial additional funding in connection with our continuing operations. 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 outlicense our technology platforms 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.

On July 24, 2017, we entered into a common stock purchase agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”), an Illinois limited liability company, pursuant to which Lincoln Park has agreed to purchase from us up to an aggregate of $16,000,000 of our common stock (subject to certain limitations) from time to time over the 36-month term of the agreement (the “Lincoln Park Purchase Agreement” or “Purchase Agreement”). As a result, on July 24, 2017, 120,000 shares of our common stock were issued to Lincoln Park as consideration for Lincoln Park’s commitment to purchase shares of our common stock under the Purchase Agreement (the “Commitment Shares”), and 250,000 shares of common stock were sold to Lincoln Park in an initial purchase for an aggregate gross purchase price of $1,000,000 (the “Initial Purchase Shares”). In connection with the Purchase Agreement, on July 24, 2017, we entered into a registration rights agreement with Lincoln Park subsequent to which we filed with the SEC a registration statement on Form S-1 to register for resale under the Securities Act of 1933, as amended, or the Securities Act, the shares of common stock that have been or may be issued to Lincoln Park under the Purchase Agreement. Since we entered into the Purchase Agreement with Lincoln Park, we have issued and sold 60,000 shares of common stock to Lincoln Park pursuant to the Purchase Agreement, not including the Commitment Shares and Initial Purchase Shares.

The extent to which we continue to utilize the Purchase Agreement as a source of funding will depend on a number of factors, including the prevailing market price of our common stock, the volume of trading in our common stock and the extent to which we are able to secure funds from other sources. The number of shares that we may sell to Lincoln Park under the Purchase Agreement on any given day and during the term of the agreement is limited. Additionally, we and Lincoln Park may not effect any sales of shares of our common stock under the Purchase Agreement during the continuance of an event of default under the term of the agreement. Even if we are able to access the full $16.0 million under the Purchase Agreement, we may still need additional capital to fully implement our business, operating and development plans.

On November 30, 2017, we completed a public offering of shares of our common stock 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.

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 to Lincoln Park under the Purchase Agreement. 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 that our existing cash on hand as of December 31, 2017 in the amount of $7.3 million, together with the proceeds of this offering, funds we expect to develop from future sales pursuant to the Lincoln Park Purchase Agreement, and proceeds realized in connection with license and collaboration arrangements and the operation of our subsidiary, iBio CDMO LLC, will be sufficient to meet our projected operating requirements going forward. 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:

Conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the data necessary to attract additional licensees and we and our current licensees may never generate the data required for product candidates to obtain the regulatory approvals necessary for product sales. Even if approved, product candidates may not achieve commercial success. Currently, we expect our commercial revenues, if any, to be product development fees, development milestone payments, and other license proceeds, including royalties derived from sales of products that we do not expect to be commercially available for several years, if at all. Accordingly, to achieve our business objectives we will need to continue to rely on additional financing which may not be available to us on acceptable terms, or at all.

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.

Raising additional capital may cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.

Until such time as we can generate substantial license, service or product revenues, we expect to finance our cash needs through a combination of equity offerings, collaborations, strategic alliances, licensing and other arrangements. Sources of funds may not be available or, if available, may not be available on terms satisfactory to us.

If we raise additional funds by issuing equity securities, our stockholders will experience dilution. Debt financing, if available, would result in increased fixed payment obligations and may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. Any debt financing or additional equity that we raise may contain terms, such as liquidation and other preferences, which are not favorable to us or our stockholders. If we raise additional funds through collaboration and licensing arrangements with third parties, it may be necessary to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, our business, operating results, financial condition and prospects could be materially and adversely affected and we may be unable to continue our operations.

To the extent that we raise additional capital through a public or private offering and sale of equity securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a stockholder. If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, our business, operating results, financial condition and prospects could be materially and adversely affected and we may be unable to continue our operations.

We have a limited operating history, which may limit the ability of investors to make an informed investment decision.

We commenced independent operations in 2008, and our operations to date have included organizing and staffing our company, business planning, raising capital, acquiring and developing our proprietary technology platforms, identifying potential product candidates and undertaking, through third parties, preclinical trials and clinical trials of product candidates derived from our technologies. Certain iBioLaunch™-derived vaccine candidates have been evaluated in completed or ongoing Phase 1 clinical trials; however, all our other vaccine and therapeutic protein product candidates are still in preclinical development. Neither we nor our collaborators have completed any other clinical trials for any vaccine or therapeutic protein product candidate produced using iBio technology. As a result, we have not yet demonstrated our ability to successfully complete any Phase 2 or pivotal clinical trials, obtain regulatory approvals, manufacture a commercial scale product, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Consequently, any conclusion you reach about our future success or viability may not be as predictive as it might be if we had a longer operating history.

We may require additional financing to sustain our operations and without it we may not be able to continue operations.

As of December 31, 2017, our accumulated deficit was approximately $79.8 million. We do not currently have sufficient financial resources to fund our operations or those of our subsidiaries. Therefore, we need additional funds to continue these operations.

We sold 250,000 shares of common stock to Lincoln Park in an initial purchase under the Purchase Agreement on July 24, 2017, for an aggregate gross purchase price of $1,000,000. Since July 24, 2017, we have sold an additional 60,000 shares of common stock to Lincoln Park for an aggregate purchase price of $121,290. We may direct Lincoln Park to purchase up to an additional $14,878,710 worth of shares of our common stock (excluding the initial purchase) under our agreement over a 36-month period generally in amounts up to 10,000 shares of our common stock, which may be increased to up to 60,000 shares of our common stock depending on the market price of our common stock at the time of sale and subject to a maximum limit of $1,000,000 per purchase, on any such business day.

The extent we rely on Lincoln Park as a source of funding will depend on a number of factors including, the prevailing market price of our common stock and the extent to which we are able to secure working capital from other sources. If obtaining sufficient funding from Lincoln Park were to prove unavailable or prohibitively dilutive, we will need to secure another source of funding in order to satisfy our working capital needs. Even if we sell all $16,000,000 under the Purchase Agreement to Lincoln Park, we may still need additional capital to fully implement our business, operating and development plans. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, the consequences could be a material adverse effect on our business, operating results, financial condition and prospects.

Risks Related to the Development and Commercialization of Our Platform Technologies and Product Candidates

We may expend our limited resources to pursue a particular technology or product candidate and fail to capitalize on technologies or product candidates that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on specific product candidates derived from or enhanced by our technologies. As a result, we may forego or delay pursuit of opportunities with other technology platforms or product candidates that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending may not yield any commercially viable products.

We have based our research and development efforts on our technologies and product candidates derived from such technologies. Notwithstanding our large investment to date and anticipated future expenditures in these technologies, we have not yet developed, and may never successfully develop, any marketed products using these technologies. As a result of our exclusive use of our own technologies, we may fail to address or develop product candidates based on other scientific approaches that may offer greater commercial potential or for which there is a greater likelihood of success.

We also may not be successful in our efforts to identify or discover additional product candidates using our technology platforms. Research programs to identify new product candidates require substantial technical, financial and human resources. These research programs may initially show promise in identifying potential product candidates, yet fail to yield product candidates for clinical development.

If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements on terms less favorable to us than possible.

We are very early in our development efforts. If we or our collaborators are unable to successfully develop and commercialize product candidates or experience significant delays in doing so, our business will be materially harmed.

Excepting a limited number of vaccine candidates that have been evaluated in completed Phase 1 clinical trials, all our other vaccine and therapeutic protein product candidates are still in preclinical development. Our ability to generate product sales revenues for our own products, which we do not expect will occur for many years, will depend heavily on the successful development and eventual commercialization of our product candidates. The success of our product candidates will depend on several factors, including the following:

If we or our collaborators do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully develop and commercialize our product candidates, which would materially harm our business.

We may not be successful in our efforts to use iBio technologies to build a pipeline of product candidates and develop marketable products.

While we believe that the data that we and our collaborators have obtained from preclinical studies and Phase 1 clinical trials of iBio-derived and iBio-enhanced product candidates has validated these technology platforms, our platforms have not yet, and may never lead to, approvable or marketable products. Even if we are successful in further validating our platforms and continuing to build our pipeline, the potential product candidates that we identify may not be suitable for clinical development for many possible reasons, including harmful side effects, limited efficacy or other characteristics that indicate that such product candidates are unlikely to be products that will receive marketing approval and achieve market acceptance. If we and our collaborators do not successfully develop and commercialize product candidates based upon our technological approach, we will not obtain product or collaboration revenues in future periods, which likely would result in significant harm to our financial position and adversely affect our stock price.

Neither we nor our licensees will be able to commercialize product candidates based on our platform technologies if preclinical studies do not produce successful results or clinical trials do not demonstrate safety and efficacy in humans.

Preclinical and clinical testing is expensive, difficult to design and implement, can take many years to complete and has an uncertain outcome. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and interim results of a clinical trial do not necessarily predict final results. We and our licensees may experience numerous unforeseen events during, or as a result of, preclinical testing and the clinical trial process that could delay or prevent the commercialization of product candidates based on our iBioLaunch and iBioModulator technologies, including the following:

Significant clinical trial delays could allow our competitors to bring products to market before we or our licensees do and impair our ability to commercialize our technologies and product candidates based on our technologies. Poor clinical trial results or delays may make it impossible to license a product candidate or so reduce its attractiveness to prospective licensees that we will be unable to successfully develop and commercialize such a product candidate.

If we are not able to obtain, or if there are delays in obtaining, required regulatory approvals, we will not be able to commercialize our product candidates or will not be able to do so as soon as anticipated, and our ability to generate revenue will be materially impaired.

Our product candidates and the activities associated with their development and commercialization, including their design, testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by the FDA and by similar regulatory authorities outside the United States. Failure to obtain marketing approval for a product candidate will prevent us from commercializing the product candidate. We have not received approval to market any of our product candidates from regulatory authorities in any jurisdiction. We have only limited experience in filing and supporting the applications necessary to gain marketing approvals and expect to rely on third parties to assist us in this process. Securing marketing approval requires the submission of extensive preclinical and clinical data and supporting information to regulatory authorities for each therapeutic indication to establish the product candidate’s safety and efficacy. Securing marketing approval also requires the submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, the regulatory authorities. Our product candidates may not be effective, may be only moderately effective or may prove to have undesirable or unintended side effects, toxicities or other characteristics that may preclude our obtaining marketing approval or prevent or limit commercial use.  If any of our product candidates receives marketing approval, the accompanying label may limit the approved use in such a restrictive manner that it is not possible to obtain commercial viability for such product.

The process of obtaining marketing approvals, both in the United States and abroad, is expensive and may take many years. If additional clinical trials are required for certain jurisdictions, these trials can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates involved, and may ultimately be unsuccessful. Changes in marketing approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review process for each submitted product application, may cause delays in the review and approval of an application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept a marketing application as deficient or may decide that our data is insufficient for approval and require additional preclinical, clinical or other studies. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit or prevent marketing approval of a product candidate. Any marketing approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable.

Although the FDA and other regulatory authorities have approved plant-based therapeutics in the past, consistent with the oversight of all products, the FDA is monitoring whether these plant-based therapeutics pose any health and human safety risks. While they have not issued any regulation to date that is adverse to plant-based vaccines or therapeutics, it is possible that the FDA and other regulatory authorities could issue regulations in the future that could adversely affect our product candidates.

If we experience delays in obtaining approval or if we fail to obtain approval of our product candidates, the commercial prospects for our product candidates may be harmed and our ability to generate revenues will be materially impaired.

Alternative technologies may supersede our technologies or make them noncompetitive, which would harm our ability to generate future revenue.

The manufacture of biologics and the methods of such manufacture are intensely competitive fields. Each of these fields is characterized by extensive research efforts, which result in rapid technological progress that can render existing technologies obsolete or economically noncompetitive. If our competitors succeed in developing more effective technologies or render our technologies obsolete or noncompetitive, our business will suffer. Many universities, public agencies and established pharmaceutical, biotechnology, and other life sciences companies with substantially greater resources than we have are developing and using technologies and are actively engaging in the development of products similar to or competitive with our technologies and products. To remain competitive, we must continue to invest in new technologies and improve existing technologies. To make such renewing investment we will need to obtain additional financing. If we are unable to secure such financing, we will not have sufficient resources to continue such investment.

Our competitors may devise methods and processes for protein expression that are faster, more efficient or less costly than that which can be achieved using iBio technologies. There has been and continues to be substantial academic and commercial research effort devoted to the development of such methods and processes. If successful competitive methods are developed, it may undermine the commercial basis for iBio products and our technologies and related services.

We have no experience in the sales, marketing and distribution of pharmaceutical products.

If we fail to establish commercial licenses for our iBio products and technologies or fail to enter into arrangements with partners with respect to the sales and marketing of any of our future potential product candidates, we might need to develop a sales and marketing organization with supporting distribution capability in order to directly market product candidates we successfully develop. Significant additional expenditures would be required for us to develop such an in-house sales and marketing organization.

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of any products that we may develop.

We face the risk of product liability exposure in connection with the testing of our product candidates in human clinical trials and will face an even greater risk if we commercially sell any products that we may develop. If we cannot successfully defend ourselves against claims that our product candidates or products caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

Prior to commencing human clinical trials, we will seek to obtain product liability insurance coverage. Such insurance coverage is expensive and may not be available in coverage amounts we seek or at all. If we obtain such coverage, we may in the future be unable to maintain such coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise.

Risks Related to Dependence on Third Parties

Establishing and maintaining collaborations is a key component of our business strategy. If we are unable to establish new collaborations and maintain both new and existing collaborations, or if these collaborations are not successful, our business could be adversely affected.

Our current business plan contemplates that we will in the future derive significant revenues from collaborators and licensees that successfully utilize iBio technologies in connection with the production, development and commercialization of vaccines and therapeutic protein product candidates. Our realization of these revenues and dependence on existing collaborations, and any future collaborations we enter into, is subject to a number of risks, including the following:

If our collaborations do not result in the successful development and commercialization of products or if one or more of our collaborators terminates its agreement with us, we may not receive any future research and development funding or milestone or royalty payments under the collaboration. If we do not receive the funding we expect under these agreements, our continued development of our product candidates could be delayed and we may need additional resources to develop additional product candidates. There can be no assurance that our collaborations will produce positive results or successful products on a timely basis or at all.

We seek to establish and collaborate with additional pharmaceutical and biotechnology companies for development and potential commercialization of iBio technology-produced and iBio technology-enhanced product candidates. We face significant competition in seeking appropriate collaborators. Our ability to reach a definitive agreement for a collaboration depends, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. If we fail to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all, we may have to curtail the development of a product candidate, reduce or delay its development or the development of one or more of our other product candidates, or increase our expenditures and undertake additional development or commercialization activities at our own expense. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to further develop our product candidates or bring them to market or continue to develop our product portfolio and our business may be materially and adversely affected.

If third parties on whom we or our licensees will rely for the conduct of preclinical studies and clinical trials do not perform as contractually required or as we expect, we may not be able to obtain regulatory approval for or commercialize our product candidates and our business may suffer.

We do not have the ability to independently conduct the preclinical studies and clinical trials required to obtain regulatory approval for our product candidates. We have not yet contracted with any third parties to conduct clinical trials of product candidates we develop independently of collaborators. We will depend on licensees or on independent clinical investigators, contract research organizations and other third party service providers to conduct the clinical trials of our product candidates. We will rely heavily on these parties for successful execution of our clinical trials but will not control many aspects of their activities. For example, the investigators participating in our clinical trials will not be our employees. However, we will be responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Third parties may not complete activities on schedule, or may not conduct our clinical trials in accordance with regulatory requirements or our stated protocols. The failure of these third parties to carry out their obligations could delay or prevent the development, approval and commercialization of our product candidates.

If revenue from a third-party customer or client is concentrated in an amount that makes up a significant percentage of our total revenues, we may be adversely impacted by the significant dependence upon that client, including but not limited to, receipt and collections of outstanding amounts, continued operational allocations toward the client and related efficiencies, capacity and opportunity costs.

At this time, we are continually promoting our technologies and CDMO capabilities to further expand and grow our revenue base and business. We will continue to consider any potential revenue and client related concentration risks. At June 30, 2017, Fiocruz represented a significant percentage, greater than 10%, of our total revenues.

Risks Related to Intellectual Property

If we or our licensors are unable to obtain and maintain patent protection for our technology and products, or if the scope of the patent protection obtained is not sufficiently broad, competitors could develop and commercialize technology and products similar or identical to ours, and our ability to successfully commercialize our technology and products may be impaired.

Our success depends in part on our ability to obtain and maintain patent and other intellectual property protection in the United States and other countries with respect to our proprietary technology and products. We seek to protect our proprietary position by filing patent applications in the United States and abroad related to our novel technologies and product candidates and by maintenance of our trade secrets through proper procedures.

The patent prosecution process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost, in a timely manner, or in all jurisdictions. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has in recent years been the subject of much litigation. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States and we may fail to seek or obtain patent protection in all major markets. For example, European patent law restricts the patentability of methods of treatment of the human body more than United States law does. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot know with certainty whether we were the first to make the inventions claimed in our owned patents or pending patent applications, or that we were the first to file for patent protection of such inventions, nor can we know whether those from whom we license patents were the first to make the inventions claimed or were the first to file. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued which protect our technology or products, in whole or in part, or which effectively prevent others from commercializing competitive technologies and products. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection.

Patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a number of significant changes to United States patent law. These include provisions that affect the way patent applications are prosecuted and may also affect patent litigation. The U.S. Patent and Trademark Office, or U.S. PTO, recently developed new regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file provisions, only became effective on March 16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business and financial condition.

Moreover, we may be subject to a third-party pre-issuance submission of prior art to the U.S. PTO, or become involved in opposition, derivation, reexamination, inter partes review, post-grant review or interference proceedings challenging our patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.

Even if our pending or future patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors from competing with us or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner.

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our patents may be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and products. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time-consuming and ultimately unsuccessful.

Competitors may infringe our issued patents or other intellectual property. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their intellectual property. In addition, in a patent infringement proceeding, a court may decide that a patent of ours is invalid or unenforceable, in whole or in part, construe the patent’s claims narrowly or refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation proceeding could put one or more of our patents at risk of being invalidated or interpreted narrowly, which could adversely affect us and our collaborators.

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the success of our business.

Our commercial success depends upon our ability, and the ability of our collaborators, to develop, manufacture, market and sell our product candidates and use our proprietary technologies without infringing the proprietary rights of third parties. There is considerable intellectual property litigation in the biotechnology and pharmaceutical industries. While no such litigation has been brought against us and we have not been held by any court to have infringed a third party’s intellectual property rights, we cannot guarantee that our technology, products or use of our products do not infringe third-party patents. It is also possible that we have failed to identify relevant third-party patents or applications. For example, applications filed before November 29, 2000 and certain applications filed after that date that will not be filed outside the United States remain confidential until patents issue. Patent applications in the United States and elsewhere are published approximately 18 months after the earliest filing, which is referred to as the priority date. Therefore, patent applications covering our products or technology could have been filed by others without our knowledge. Additionally, pending patent applications which have been published can, subject to certain limitations, be later amended in a manner that could cover our technologies, our products or the use of our products.

We may become party to, or threatened with, future adversarial proceedings or litigation regarding intellectual property rights with respect to our products and technology, including interference or derivation proceedings before the U.S. PTO and similar bodies in other countries. Third parties may assert infringement claims against us based on existing intellectual property rights and intellectual property rights that may be granted in the future.

If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue developing and marketing our products and technology. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forced, including by court order, to cease commercializing the infringing technology or product. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our product candidates or force us to cease some of our business operations, which could materially harm our business. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business.

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses, and could distract our limited number of personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could compromise our ability to compete in the marketplace.

If we are unable to protect our trade secrets, our business and competitive position would be harmed.

In addition to seeking patents for some of our technology and product candidates, we also rely on trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position. We seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators, outside scientific collaborators, contract manufacturers, consultants, advisors and other third parties. We also seek to enter into confidentiality and invention or patent assignment agreements with our employees and consultants. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Our trade secrets may also be obtained by third parties by other means, such as breaches of our physical or computer security systems. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed.

Risks Related to iBio CDMO’s Operations

If iBio CDMO is unable to provide quality and timely offerings to its customers, its business could suffer, which could have a material adverse impact on our business and results of operations.

In January 2016, we entered into a contract manufacturing joint venture operated through our subsidiary iBio CDMO. iBio CDMO operates 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 (3) commercial technology transfer services. iBio CDMO’s operations take place in Bryan, Texas in a facility controlled by an affiliate of Eastern Capital Limited (“Eastern”), a stockholder of the Company, as sublandlord. The facility is a Class A life sciences building on the campus of Texas A&M University, designed and equipped for plant-made manufacture of biopharmaceuticals.

A failure of quality control systems in iBio CDMO’s facilities could cause problems to arise in connection with facility operations or during preparation or provision of products, in both cases, for a variety of reasons, including equipment malfunction, failure to follow specific protocols and procedures, problems with raw materials or environmental factors. Such problems could affect production of a particular batch or series of batches, requiring the destruction of products, or could halt facility production altogether. In addition, failure to meet required quality standards may result in failure to timely deliver products to customers. Any such incident could, among other things, lead to increased costs, lost revenue, reimbursement to customers, damage to and possibly termination of existing customer relationships, time and expense spent investigating the cause and, depending on the cause, similar losses with respect to other batches or products. If problems are not discovered before a product is released to the market, we may be subject to regulatory actions, including product recalls, product seizures, injunctions to halt manufacture and distribution, restrictions on our operations, civil sanctions, including monetary sanctions, and criminal actions. In addition, such issues could subject us to litigation, the cost of which could be significant.

A failure by iBio CDMO to attract and maintain customers and any reduction in spending or demand for iBio CDMO’s manufacturing, development and technology transfer services could have a material adverse effect on our business.

iBio CDMO’s operations will depend, in part, on its ability to attract and maintain customers for its development, manufacturing and technology transfer services and on the amount of customer spending on such services. If iBio CDMO fails to attract customers or its customers’ and potential customers’ spending on iBio CDMO’s services is reduced, this may have a material adverse effect on our business, results of operations and financial condition.

iBio CDMO’s operations are subject to environmental, health and safety laws and regulations, which could increase costs and restrict operations in the future.

iBio CDMO’s operations are subject to a variety of environmental, health and safety laws and regulations, including those of the Environmental Protection Agency and equivalent local and state agencies. These laws and regulations govern, among other things, air emissions, wastewater discharges, the use, handling and disposal of hazardous substances and wastes, soil and groundwater contamination and employee health and safety. Any failure to comply with environmental, health and safety requirements could result in the limitation or suspension of production or monetary fines or civil or criminal sanctions, or other future liabilities. iBio CDMO is also subject to laws and regulations governing the destruction and disposal of raw materials and the handling and disposal of regulated material.

A failure by iBio CDMO to hire and retain an appropriately skilled and adequate workforce could adversely impact the ability of the facility to operate and function efficiently.

iBio CDMO’s operations will depend, in part, on its ability to attract and retain an appropriately skilled and sufficient workforce to operate its development and manufacturing facility. The facility is located in a growing biotechnology hub and competition for skilled workers will continue to increase as the industry undergoes further growth in the area.

Risks Related to Business Operations

If we acquire companies, products or technologies, we may face integration risks and costs associated with those acquisitions that could negatively impact our business, results from operations and financial condition.

If we are presented with appropriate opportunities, we may acquire or make investments in complementary companies, products or technologies. We may not realize the anticipated benefit of any acquisition or investment. If we acquire companies or technologies, we will face risks, uncertainties and disruptions associated with the integration process, including difficulties in the integration of the operations of an acquired company, integration of acquired technology with our products, diversion of our management’s attention from other business concerns, the potential loss of key employees or customers of the acquired business, and impairment charges if future acquisitions are not as successful as we originally anticipate. In addition, our operating results may suffer because of acquisition-related costs or amortization expenses or charges relating to acquired intangible assets. Any failure to successfully integrate other companies, products or technologies that we may acquire may have a material adverse effect on our business and results of operations. Furthermore, we may have to incur debt or issue equity securities to pay for any additional future acquisitions or investments, the issuance of which could be dilutive to our existing stockholders.

Our future success depends on our ability to retain our officers and directors, scientists, and other key employees and to attract, retain and motivate qualified personnel.

Our success depends on our ability to attract, retain and motivate highly qualified management and scientific personnel. In particular, we are highly dependent on Robert B. Kay, our Executive Chairman and Chief Executive Officer, our other officers and directors, scientists and key employees. The loss of any of these persons or their expertise would be difficult to replace and could have a material adverse effect on our ability to achieve our business goals. In addition, the loss of the services of any one of these persons may impede the achievement of our research, development and commercialization objectives by diverting management’s attention to the identification of suitable replacements, if any. There can be no assurance that we will be successful in hiring or retaining qualified personnel, and our failure to do so could have a material adverse effect on our business, financial condition and results of operations.

We face intense competition, including from companies with greater resources and experience than us, which may negatively affect our commercial opportunities.

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. We face competition from many different sources, including commercial pharmaceutical and biotechnology enterprises, academic institutions, government agencies, and private and public research institutions. Our commercial opportunities will be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer side effects or are less expensive than any products that we or our collaborators may develop based on the use of our technologies.

Many of our competitors have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, clinical trials, regulatory approvals and marketing approved products than we do. Smaller or early stage companies may also prove to be significant competitors, particularly through arrangements with large and established companies, and this may reduce the value of our technologies for the purposes of establishing license agreements. In addition, these third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies and technology licenses complementary to our programs or advantageous to our business.

We expect to rely upon licensees, collaborators or customers for support in advancing certain of our drug candidates and intend to rely on additional work with our collaborators during our efforts to commercialize our product candidates. Our licensees, collaborators or customers may be conducting multiple product development efforts within the same disease areas that are the subjects of their agreements with us. Agreements with collaborators may not preclude them from pursuing development efforts using a different approach from that which is the subject of our agreement with them. Any of our drug candidates, therefore, may be subject to competition with a drug candidate under development by a customer.

For all the foregoing reasons, we may not be able to compete successfully against our competitors.

Risks Related to Our Stock Purchase Agreement with Lincoln Park

Sales of our common stock to Lincoln Park may cause substantial dilution to our existing stockholders and the sale of the shares of our common stock acquired by Lincoln Park could cause the price of our common stock to decline.

On July 24, 2017, we entered into the Purchase Agreement with Lincoln Park pursuant to which Lincoln Park has agreed to purchase from us up to an aggregate of $16,000,000 of our common stock (subject to certain limitations) from time to time over the 36-month term of the Purchase Agreement. As a result, on July 24, 2017, 120,000 shares of our common stock were issued to Lincoln Park as consideration for Lincoln Park’s commitment to purchase shares of our common stock under the Purchase Agreement (the “Commitment Shares”), and 250,000 shares of common stock (the “Initial Purchase Shares”) were sold to Lincoln Park in an initial purchase for an aggregate gross purchase price of $1,000,000 (the “Initial Purchase Amount”). Since we entered into the Purchase Agreement with Lincoln Park, we have issued and sold 60,000 shares of common stock to Lincoln Park pursuant to the Purchase Agreement for an aggregate gross purchase price of $121,290 not including the Commitment Shares and Initial Purchase Shares.

The number of shares ultimately offered for sale to Lincoln Park is dependent upon the number of shares we elect to sell to Lincoln Park under the Purchase Agreement. Depending upon market liquidity at the time, sales of shares of our common stock under the Purchase Agreement may cause the trading price of our common stock to decline. Lincoln Park may ultimately purchase all or only some of the $16.0 million of our common stock that we may sell under the Purchase Agreement. After Lincoln Park acquires shares under the Purchase Agreement, it may sell all, some or none of those shares. Sales to Lincoln Park by us pursuant to the Purchase Agreement may result in substantial dilution to the interests of other holders of our common stock. The sale of a substantial number of shares of our common stock to Lincoln Park, 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. However, we have the right to control the timing and amount of any sales of our shares to Lincoln Park, and we may terminate the Lincoln Park Purchase Agreement at any time at our discretion without any cost to us.

Our management has broad discretion over the amounts, timing and use of the net proceeds that we may receive pursuant to the Purchase Agreement, you may not agree with how we use the proceeds, and the proceeds may not be invested successfully.

Our management has broad discretion in the timing and application of any net proceeds that we may receive from any future sales of common stock to Lincoln Park pursuant to the Purchase Agreement. Management could use these proceeds for purposes other than those currently contemplated. Accordingly, you will be relying on the judgment of our management with regard to the timing and use of these net proceeds, and you will not have the opportunity as part of your investment decision to assess whether the proceeds are being used appropriately. It is possible that the proceeds will be invested in a way that does not yield a favorable, or any, return for our company.

The extent to which we utilize the Lincoln Park Purchase Agreement as a source of funding will depend on a number of factors, including the prevailing market price of our common stock, the volume of trading in our common stock and the extent to which we are able to secure funds from other sources. The number of shares that we may sell to Lincoln Park under the Purchase Agreement on any given day and during the term of the Purchase Agreement is limited. Additionally, we and Lincoln Park may not effect any sales of shares of our common stock under the Purchase Agreement during the continuance of an event of default under the Purchase Agreement. Even if we are able to access the full $16.0 million under the Purchase Agreement, we may still need additional capital to fully implement our business, operating and development plans.

We may not be able to access the full amounts available under the Purchase Agreement, which could prevent us from accessing the capital we need to continue our operations, which could have an adverse effect on our business.

Other than the Initial Purchase Amount, all funds available under the Purchase Agreement are only available if our common stock per share value is $0.25 or higher at the time we seek to sell stock, and the volume of any such stock sales under the Purchase Agreement may vary with our common stock per share price. Changes in our stock price may limit the net proceeds we may receive under the Purchase Agreement.

Risks Relating to this Offering and Ownership of Our Common Stock, Series A Preferred Stock or Series B Preferred Stock

Our stock price may be volatile or may decline regardless of our operating performance, and you may not be able to resell Shares, Series A Preferred Shares or Series B Preferred Shares at or above the price you paid or at all, and you could lose all or part of your investment as a result.

The stock market in general and the market for biotechnology and other life sciences companies in particular, have experienced extreme volatility that has often been unrelated to the operating performance of these companies. Therefore, the value of our common stock may decline regardless of our operating performance or prospects. The market price of our common stock at any particular time may not remain the market price in the future. The market price for our common stock may be influenced by many factors, including those factors described in this “Risk Factors” section and:

Our operating results may vary significantly in the future, which may adversely affect the price of our common stock.

It is likely that our operating results may vary significantly in the future and that period-to-period comparisons of our operating results are not necessarily meaningful indicators of the future. You should not rely on the results of one quarter as an indication of our future performance. It is also possible that in some future quarters our operating results will fall below our expectations or the expectations of market analysts and investors. If we do not meet these expectations, the price of our common stock may decline significantly.

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

Our shares of common stock are currently listed on the NYSE American. If we fail to satisfy the continued listing requirements of the NYSE American, such as the corporate governance requirements, minimum bid price requirement or the minimum stockholder’s equity requirement, the NYSE American may take steps to delist our common stock. Any delisting would likely have a negative effect on the price of our common stock and would impair stockholders’ ability to sell or purchase their common stock when they wish to do so.

On January 4, 2018, as a result of the Company’s then low per share price, the Company received notice from the NYSE American that we needed to effect a reverse stock split or otherwise demonstrate sustained improvement in our share price within a reasonable period of time in order to maintain our continued listing on the NYSE American.

To regain compliance with the NYSE American’s listing standards, the Company held a special meeting of its stockholders on April 23, 2018, at which the stockholders approved a proposal to effect an amendment our certificate of incorporation, as amended, to implement a reverse stock split at a ratio to be determined by the Board in a range not less than one-for-two (1:2) and not greater than one-for-ten (1:10). Our Board determined to implement a reverse stock split at a ratio of one-for-ten (1:10) shares of the Company’s common stock. The reverse stock split was effective on June 8, 2018.

On June 6, 2018, the Company received notice from the NYSE American that the Company currently is below the NYSE American’s continued listing standards set forth in 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 sustained losses from continuing operations and/or net losses in its five most recent fiscal years. The exchange indicated that a review of the Company shows that the Company is below compliance with Section 1003(a)(iii) since it reported stockholders’ equity of $4.2 million as of March 31, 2018 and net losses in its five most recent fiscal years.

The Company must submit a plan of compliance to the NYSE American by July 6, 2018 that explains how the Company intends to regain compliance with Section 1003(a)(iii) of the NYSE American Company Guide by December 6, 2019. If the Company does not submit a plan of compliance, or if the plan is not accepted by the NYSE American, the Company will be subject to delisting procedures as set forth in Section 1010 and Part 12 of the NYSE American Company Guide. If the plan is accepted by the NYSE American, the Company will be subject to periodic reviews including quarterly monitoring for compliance with the plan.

The Company believes it can provide the NYSE American with a satisfactory plan by July 6, 2018, to show that it will be able to return to compliance with Section 1003(a)(iii) of the NYSE American Company Guide by December 6, 2019.

The Company’s common stock will continue to be listed on the NYSE American while it attempts to regain compliance with the listing standards noted, subject to the Company’s compliance with other continued listing requirements. The Company’s common stock will continue to trade under the symbol “IBIO,” but will have an added designation of “.BC” to indicate that the Company is not in compliance with the NYSE American’s listing standards.

If our common stock loses its status on the NYSE American, we believe that our shares of common stock would likely be eligible to be quoted on the inter-dealer electronic quotation and trading system operated by Pink OTC Markets Inc., commonly referred to as the Pink Sheets and now known as the OTCQB market. Our common stock may also be quoted on the Over-the-Counter Bulletin Board, an electronic quotation service maintained by the Financial Industry Regulatory Authority. These markets are generally not considered to be as efficient as, and not as broad as, the NYSE American. In the event of any delisting, it could be more difficult to buy or sell our common stock and obtain accurate quotations, and the price of our stock could suffer a material decline. Delisting may also impair our ability to raise capital.

Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable.

Provisions of our certificate of incorporation, as amended, 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.

We do not anticipate paying cash dividends for the foreseeable future, and therefore investors should not buy our stock if they wish to receive cash dividends.

We have never declared or paid any cash dividends or distributions on our capital stock. We currently intend to retain our future earnings to support operations and to finance expansion and therefore we do not anticipate paying any cash dividends on our common stock in the foreseeable future. Since we do not intend to pay cash dividends, your ability to receive a return on your investment will depend on any future appreciation in the market value of our common stock. There is no guarantee that our common stock, Series A Preferred Stock or Series B Preferred Stock will appreciate or even maintain the price at which our holders have purchased such securities.

There is no active, public market for the Series A Preferred Shares or Series B Preferred Shares being offered in this offering.

There is no established public trading market for the Series A Preferred Shares or Series B Preferred Shares being offered in this offering. We do not intend to apply to list the Series A Preferred Shares or Series B Preferred Shares on a securities exchange. Without an active trading market, the liquidity of the Series A Preferred Shares and Series B Preferred Shares will be limited.

The Series A Preferred Stock and Series B Preferred Stock have limited voting rights.

Holders of Series A Preferred Stock and holders of Series B Preferred Stock will not have the right to vote for members of the Company’s board of directors and will not vote on an as-converted to common stock basis for matters brought before the Company’s common stockholders. The holders of Series A Preferred Stock will have the right to vote only on certain material changes in the terms of the Series A Preferred Stock and on other matters as may be required by Delaware law. The holders of Series B Preferred Stock will have the right to vote only on certain material changes in the terms of the Series B Preferred Stock and on other matters as may be required by Delaware law.

Our management will have broad discretion over how the Company will use the funds raised in this offering and may use them in ways that you may not agree with and that may not enhance our operating results or the price of our common stock.

Our management will have broad discretion over the use of proceeds from this offering and could use these proceeds for purposes other than those contemplated at the time of this prospectus. Accordingly, you will be relying on the judgment of our management with regard to the timing and use of these funds, and you will not have the opportunity as part of your investment decision to assess whether the proceeds are being used appropriately. It is possible that the proceeds will be invested in a way that does not yield a favorable, or any, return for our company. Our failure to apply these funds effectively could harm our business and cause the price of our common stock to decline.

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, as amended, to issue up to 275 million shares of common stock, par value $.001 per share, and 1 million shares of preferred stock, with no par value, one of which is designated as iBio CMO Preferred Tracking Stock, par value, $0.001. As of June 8, 2018, we had issued and outstanding approximately 11.6 million shares of common stock and one share of iBio CMO Preferred Tracking Stock. No other shares of preferred stock are outstanding. In addition, as of June 8, 2018, 1.38 million options to purchase shares of common stock were outstanding and we had approximately 124,000 shares of common stock reserved for future issuance of additional option grants under our 2008 Omnibus Equity Incentive Plan.

Accordingly, we are able to issue up to approximately 262 million additional shares of common stock (which includes common stock issuable under this prospectus) and 999,999 shares of preferred stock. 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.

The issuance of preferred stock or additional shares of common stock could adversely affect the rights of the holders of shares of our common stock, Series A Preferred Stock or Series B Preferred Stock.

Our Board of Directors is authorized to issue up to 999,999 shares of preferred stock without any further action on the part of our stockholders. Our Board of Directors has the authority to fix and determine the voting rights, rights of redemption and other rights and preferences of preferred stock. Currently, we have one share of preferred stock outstanding and we are offering Series A Preferred Shares and Series B Preferred Shares. Our Board of Directors may, at any time, authorize the issuance of a series of preferred stock that would grant to holders the preferred right to our assets upon liquidation, the right to receive dividend payments before dividends are distributed to the holders of common stock, and the right to the redemption of the shares, together with a premium, before the redemption of our common stock, which may have a material adverse effect on the rights of the holders of our common stock. In addition, our Board of Directors, without further stockholder approval, may, at any time, issue large blocks of preferred stock. In addition, the ability of our Board of Directors to issue shares of preferred stock without any further action on the part of our stockholders may impede a takeover of our company and may prevent a transaction that is favorable to our stockholders.

FORWARD-LOOKING STATEMENTS

This prospectus contains 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 estimate that the net proceeds from our issuance and sale of 5,555,556 Shares, 6,000 Series A Preferred Shares and 6,000 Series B Preferred Shares in this offering will be approximately $16,954,713, or approximately $19,518,228 if the Underwriter exercises its over-allotment option to purchase additional Shares in full, assuming an offering price of $1.08 per Share, the last reported sale price of our common stock on the NYSE American on  June 19, 2018, $1,000 per Series A Preferred Share and $1,000 per Series B Preferred Share, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us. We intend to use the net proceeds from this offering for working capital and general corporate purposes.

We have not yet determined the amount of net proceeds to be used specifically for any particular purpose or the timing of these expenditures. Accordingly, our management will have significant discretion and flexibility in applying the net proceeds from this offering. Pending our use of the net proceeds from this offering, we intend to invest a portion of the net proceeds in a variety of capital preservation investments, including short-term, interest-bearing instruments and United States government securities.

MARKET PRICE AND DIVIDEND INFORMATION

Market Information

Our common stock is traded on the NYSE American under the trading symbol “IBIO”.

The following table sets forth the high and low sale prices of our common stock on the NYSE American. The quotations shown represent inter-dealer prices without adjustment for retail markups, markdowns or commissions, and may not necessarily reflect actual transactions. On June 8, 2018, the Company effected a 1 for 10 reverse stock split. The quotations shown below have been retroactively adjusted to reflect the reverse stock split.

The closing price of our common stock on the NYSE American on June 19, 2018 was $1.08 per share. As of June 19, 2018, we had 11,591,827 shares of common stock outstanding, which were held by approximately 94 stockholders of record.

Dividends

We have never declared or paid any cash dividends on our common stock.

CAPITALIZATION

The following table sets forth our cash and cash equivalents, as well as our capitalization, as of December 31, 2017 as follows:

The as adjusted information set forth below is illustrative only and will be adjusted based on the actual public offering price and other terms of this offering determined at pricing. You should read this information in conjunction the information contained in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our audited consolidated financial statements and related notes thereto in our Annual Report on Form 10-K for the year ended June 30, 2017, which is incorporated by reference in the prospectus.

The number of shares of common stock shown above to be outstanding after this offering is based on 11,591,827 shares of common stock outstanding as of June 19, 2018, which excludes:

The number of shares of our common stock outstanding after this offering will fluctuate depending on how many Series A Preferred Shares and Series B Preferred Shares are sold in this offering and whether and to what extent holders of Series A Preferred Shares and the holders of Series B Preferred Shares convert their shares to common stock.

dilution

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

Our historical net tangible book deficit as of December 31, 2017 was $6.1 million, 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 December 31, 2017.

After giving effect to the issuance and sale of 5,555,556 Shares in this offering at an assumed public offering price of $1.08 per Share, the last reported sale price of our common stock on the NYSE American on June 18 , 2018, and after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value/deficit as of December 31, 2017 would have been $11.8 million, or $0.69 per Share (as adjusted to take into account a 1 for 10 reverse split the Company’s common stock, which was effective as of June 8, 2018). This represents an immediate decrease in net tangible book deficit/value per share of $5.7 to existing stockholders and immediate dilution of $0.64 per share to new investors purchasing common stock in this offering. Dilution per share to new investors is determined by subtracting as adjusted net tangible book value per share after this offering from the public offering price per Share paid by new investors. The following table illustrates this dilution on a per share basis:

Each $0.05 increase (decrease) in the assumed public offering price of $1.08 per Share, the last reported sale price of our common stock on the NYSE American on June 19, 2018, would increase (decrease) our as adjusted net tangible book value per share after this offering by approximately $0.3 million, and the dilution per share to new investors purchasing Shares in this offering by $0.02 , assuming the number of Shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We may also increase or decrease the number of Shares to be issued in this offering. Each increase (decrease) of 555,556 Shares offered by us would (increase) decrease our as adjusted net tangible book value per share by $0.6 million and the dilution per share to new investors purchasing Shares in this offering by $0.03 assuming that the assumed public offering price remains the same, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. The information discussed above is illustrative only and will be adjusted based on the actual public offering price of the Shares and other terms of this offering as determined between us and the Underwriter at pricing.

If the Underwriter exercises its over-allotment option to purchase additional Shares in full, the as adjusted net tangible book value per share after this offering would be $0.84 per share, the increase in net tangible book value per share to existing stockholders would be $0.79 per share and the dilution to new investors purchasing Shares in this offering would be $0.05 per share.

The number of shares of common stock shown above to be outstanding after this offering is based on 11,591,827 shares of common stock outstanding as of June 19, 2018, which excludes:

To the extent that options or warrants are exercised, new options or other securities are issued under our equity compensation plans, or we issue additional shares of common stock in the future, there will 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.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information with respect to the beneficial ownership of our outstanding common stock as of June 19, 2018:

Except as otherwise noted in the footnotes below, to our knowledge, each of the persons named in this table has sole voting and investment power with respect to the securities indicated as beneficially owned.

All common shares, stock options, and per share information presented in the table and footnotes below have been adjusted on a retroactive basis to reflect the 1 for 10 reverse stock split of the Company’s common stock, which was effective as of June 8, 2018.

DESCRIPTION OF SECURITIES

Capital Stock

We are authorized to issue 275,000,000 shares of common stock, par value $0.001 per share, of which 11,591,827 shares were issued and outstanding as of June 19, 2018, and 1,000,000 shares of preferred stock, no par value, one of which is designated as iBio CMO Preferred Tracking Stock, par value, $0.001, per share. As of June 19, 2018, one share of iBio CMO Preferred Tracking Stock is issued and outstanding and no other shares of preferred stock are outstanding.

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:

·       Diluting the voting or other rights of the proposed acquirer or insurgent stockholder group,

·       Putting a substantial voting block in institutional or other hands that might undertake to support the incumbent Board of Directors, or

·       Effecting an acquisition that might complicate or preclude the takeover.

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

We are authorized to issue 1,000,000 shares of preferred stock, with no par value, and the Board of Directors is authorized to create one or more series of preferred stock, and to designate the rights, privileges, restrictions, preferences and limitations of any given series of preferred stock. Accordingly, the Board of Directors may, without stockholder approval, issue shares of preferred stock with dividend, liquidation, conversion, voting or other rights that could adversely affect the voting power or other rights of the holders of common stock.

Series A Convertible Preferred Stock

The following is a summary of the material terms of the Series A Preferred Stock. This summary is not complete. The following summary of the terms and provisions of the Series A Preferred Stock is qualified in its entirety by reference to the Series A Preferred Stock, the form of which has been filed as an exhibit to the registration statement of which this prospectus is a part.

General

Our board of directors has designated up to 6,000 shares of the 1,000,000 authorized shares of preferred stock as Series A Convertible Preferred Stock, par value $0.001 per share. When issued, the shares of Series A Preferred Stock will be validly issued, fully paid and non-assessable. Each share of Series A Preferred Stock will have a stated value of $1,000 per share.

Rank

The Series A Preferred Stock will rank on parity to our common stock and Series B Preferred Stock and junior to our iBio CMO Preferred Tracking Stock described below under “Preferred Tracking Stock”.

Conversion

Each share of Series A Preferred Stock is convertible into shares of our common stock (subject to adjustment as provided in the related certificate of designation of preferences, rights and limitations) at any time at the option of the holder at a conversion price equal to the public offering price of the common stock in this offering. The conversion price is subject to adjustment if, at any time during the two (2) years following the first issuance of shares of Series A Preferred Stock, we issue any shares of common stock or options, warrants or other securities exercisable for or convertible into common stock at a price per share less than the conversion price in effect at such time. In such case the conversion price will be adjusted to the higher of the price per share in such subsequent issuance or $0.05. Certain exempt issuances, such as options to purchase common stock issued to officers, directors and employees pursuant to an option plan duly adopted by a majority of the non-employee members of our Board of Directors or a majority of the members of a committee of non-employee directors established for such purpose, issuances of shares of common stock pursuant to convertible securities currently outstanding, and issuances of shares in connection with strategic transactions approved by a majority of our disinterested directors do not result in an adjustment to the conversion price.

Holders of Series A Preferred Stock will be prohibited from converting Series A Preferred Stock into shares of our common stock if, as a result of such conversion, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of our common stock then issued and outstanding. However, any holder may increase or decrease such percentage to any other percentage not in excess of 9.99%, provided that any increase in such percentage shall not be effective until 61 days after such notice to us.

Liquidation Preference

In the event of our liquidation, dissolution or winding-up, holders of Series A Preferred Stock will be entitled to receive the same amount that a holder of our common stock would receive if the Series A Preferred Stock were fully converted into shares of our common stock at the conversion price (disregarding for such purposes any conversion limitations) which amounts shall be paid pari passu with all holders of common stock and holders of Series B Preferred Stock.

Voting Rights

Holders of Series A Preferred Stock will not have the right to vote for members of the Company’s board of directors and will not vote on an as-converted to common stock basis for matters brought before the Company’s common stockholders. The affirmative vote of the holders of a majority of the then outstanding shares of Series A Preferred Stock is required to, (a) alter or change adversely the powers, preferences or rights given to the Series A Preferred Stock, (b) amend our certificate of incorporation or other charter documents in any manner that materially adversely affects any rights of the holders of Series A Preferred Stock, (c) increase the number of authorized shares of Series A Preferred Stock, (c) issue any shares of Series A Preferred Stock other than pursuant to the certificate of designation of preferences, rights and limitations of the Series A Preferred Stock, or (d) enter into any agreement with respect to any of the foregoing.

Dividends

Shares of Series A Preferred Stock will not be entitled to receive any dividends, unless and until specifically declared by our board of directors. The holders of the Series A Preferred Stock will participate, on an as-if-converted-to-common stock basis, in any dividends to the holders of common stock.

Redemption

We are not obligated to redeem or repurchase any shares of Series A Preferred Stock. Shares of Series A Preferred Stock are not otherwise entitled to any redemption rights or mandatory sinking fund or analogous fund provisions.

General

Our board of directors has designated up to 6,000 shares of the 1,000,000 authorized shares of preferred stock as Series B Convertible Preferred Stock, par value $0.001 per share. When issued, the shares of Series B Preferred Stock will be validly issued, fully paid and non-assessable. Each share of Series B Preferred Stock will have a stated value of $1,000 per share.

Rank

The Series B Preferred Stock will rank on parity to our common stock and Series A Preferred Stock and junior to our iBio CMO Preferred Tracking Stock described below under “Preferred Tracking Stock”.

Conversion

Each share of Series B Preferred Stock is convertible into shares of our common stock (subject to adjustment as provided in the related certificate of designation of preferences, rights and limitations) at any time at the option of the holder at a conversion price equal to the public offering price of the common stock in this offering. The conversion price is subject to adjustment if, at any time during the two (2) years following the first issuance of shares of Series B Preferred Stock, we issue any shares of common stock or options, warrants or other securities exercisable for or convertible into common stock at a price per share less than the conversion price in effect at such time. In such case the conversion price will be adjusted to the higher of the price per share in such subsequent issuance or $0.05. Certain exempt issuances, such as options to purchase common stock issued to officers, directors and employees pursuant to an option plan duly adopted by a majority of the non-employee members of our Board of Directors or a majority of the members of a committee of non-employee directors established for such purpose, issuances of shares of common stock pursuant to convertible securities currently outstanding, and issuances of shares in connection with strategic transactions approved by a majority of our disinterested directors do not result in an adjustment to the conversion price.

Holders of Series B Preferred Stock will be prohibited from converting Series B Preferred Stock into shares of our common stock if, as a result of such conversion, the holder, together with its affiliates, would own more than 48% of the total number of shares of our common stock then issued and outstanding.

In the event of our liquidation, dissolution or winding-up, holders of Series B Preferred Stock will be entitled to receive the same amount that a holder of our common stock would receive if the Series B Preferred Stock were fully converted into shares of our common stock at the conversion price (disregarding for such purposes any conversion limitations) which amounts shall be paid pari passu with all holders of common stock and holders of Series A Preferred Stock.

Voting Rights

Holders of Series B Preferred Stock will not have the right to vote for members of the Company’s board of directors and will not vote on an as-converted to common stock basis for matters brought before the Company’s common stockholders.

Dividends

Shares of Series B Preferred Stock will not be entitled to receive any dividends, unless and until specifically declared by our board of directors. The holders of the Series B Preferred Stock will participate, on an as-if-converted-to-common stock basis, in any dividends to the holders of common stock.

Redemption

We are not obligated to redeem or repurchase any shares of Series B Preferred Stock. Shares of Series B Preferred Stock are not otherwise entitled to any redemption rights or mandatory sinking fund or analogous fund provisions.

Exchange Listing

We do not plan on making an application to list the Series B Preferred Stock on any national securities exchange or other nationally recognized trading system.

Preferred Tracking Stock 

On February 23, 2017, our Board of Directors created a series of preferred stock, designated as the “iBio CMO Preferred Tracking Stock,” par value $0.001 per share (the “Preferred Tracking Stock”), out of our 1,000,000 authorized shares of preferred stock. On February 23, 2017, we filed with the Secretary of State of the State of Delaware a certificate of designation, preferences and rights of the Preferred Tracking Stock (the “Certificate of Designation”) which became effective on February 23, 2017, authorizing one share of Preferred Tracking Stock and establishing the designation, powers, preferences and rights of the Preferred Tracking Stock.

Dividends on Preferred Tracking Stock

The Preferred Tracking Stock accrues dividends at the rate of 2% per annum on the original issue price of $13 million per share. Accrued dividends are payable if and when declared by the Board of Directors, upon an exchange of the shares of Preferred Tracking Stock and upon a liquidation, winding up or deemed liquidation (such as a merger) of the Company. No dividend may be declared or paid or set aside for payment or other distribution declared or made upon our common stock and no common stock may be redeemed, purchased or otherwise acquired for any consideration by us unless all accrued dividends on all outstanding shares of Preferred Tracking Stock are paid in full.

Voting Rights of Preferred Tracking Stock

The holders of Preferred Tracking Stock, voting separately as a class, are entitled to approve by the affirmative vote of a majority of the shares of Preferred Tracking Stock outstanding any amendment, alteration or repeal of any of the provisions of, or any other change to, our certificate of incorporation, as amended, or the Certificate of Designation that adversely affects the rights, powers or privileges of the Preferred Tracking Stock, any increase in the number of authorized shares of Preferred Tracking Stock, the issuance or sale of any additional shares of Preferred Tracking Stock or any securities convertible into or exercisable or exchangeable for Preferred Tracking Stock, the creation or issuance of any shares of any additional class or series of capital stock unless the same ranks junior to the Preferred Tracking Stock, or the reclassification or alteration of any of our existing securities that are junior to or pari passu with the Preferred Tracking Stock, if such reclassification or alteration would render such other security senior to the Preferred Tracking Stock. Except as required by applicable law, the holders of Preferred Tracking Stock have no other voting rights.

Exchange of Preferred Tracking Stock

At our election or the election of holders of a majority outstanding shares of Preferred Tracking Stock, each outstanding share of Preferred Tracking Stock may be exchanged for 29,990,000 units of limited liability company interests of iBio CDMO. Such exchange may be effected only after March 31, 2018, or in connection with a winding up, liquidation or deemed liquidation (such as a merger) of the Company or iBio CDMO. In addition, such exchange will take effect upon a change in control of iBio CDMO.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Our certificate of incorporation, as amended, will provide 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 first amended and restated bylaws 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.

MATERIAL U.S. FEDERAL INCOME AND

ESTATE TAX CONSEQUENCES TO NON-U.S. HOLDERS

The following is a summary of the material U.S. federal income tax consequences of the ownership and disposition of our common stock to Non-U.S. Holders (defined below), but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the Code, Treasury regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed or subject to differing interpretations, possibly with retroactive effect, so as to result in United States federal income tax consequences different from those set forth below. We have not sought and will not seek any ruling from the Internal Revenue Service, or the IRS, with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will agree with such statements and conclusions.

This summary also does not address the tax considerations arising under the laws of any United States state or local or any non-United States jurisdiction, the 3.8% Medicare tax on net investment income or any alternative minimum tax consequences. In addition, this discussion does not address tax considerations applicable to a Non-U.S. Holder’s particular circumstances or to a Non-U.S. Holder that may be subject to special tax rules, including, without limitation:

In addition, if a partnership, including any entity or arrangement classified as a partnership for United States federal income tax purposes, holds our common stock, the tax treatment of a partner generally will depend on the status of the partner, the activities of the partnership, and certain determinations made at the partner level. Accordingly, partnerships that hold our common stock, and partners in such partnerships, should consult their tax advisors regarding the United States federal income tax consequences to them of the purchase, ownership, and disposition of our common stock.

You are urged to consult your tax advisor with respect to the application of the United States federal income tax laws to your particular situation, as well as any tax consequences of the purchase, ownership and disposition of our common stock arising under the U.S. federal estate or gift tax rules or under the laws of any United States state or local or any non-United States or other taxing jurisdiction or under any applicable tax treaty.

Definition of a Non-U.S. holder

For purposes of this summary, a “Non-U.S. Holder” is any beneficial owner of our common stock that is not a “U.S. person,” and is not a partnership, or an entity disregarded from its owner, each for U.S. federal income tax purposes. A U.S. person is any person that, for United States federal income tax purposes, is or is treated as any of the following:

Distributions

As discussed in the section entitled “Market Price and Dividend Information” beginning on page 33 of this prospectus, we do not anticipate paying any dividends on our capital stock in the foreseeable future. If we make distributions on our common stock, those payments will constitute dividends for United States income tax purposes to the extent we have current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce a Non-U.S. Holder’s basis in our common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under the “Gain on Sale or Other Disposition of Common Stock” section. Any such distributions would be subject to the discussions below regarding back-up withholding and Foreign Account Tax Compliance Act, or FATCA.

Subject to the discussion below on effectively connected income, any dividend paid to a Non-U.S. Holder generally will be subject to U.S. withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty. To receive a reduced treaty rate, a Non-U.S. Holder must provide us or our agent with an IRS Form W-8BEN (generally including a United States taxpayer identification number), IRS Form W-8-BEN-E or another appropriate version of IRS Form W-8 (or a successor form), which must be updated periodically, and which, in each case, must certify qualification for the reduced rate. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

Dividends paid to a Non-U.S. Holder that are effectively connected with the Non-U.S. Holder’s conduct of a United States trade or business within the United States and that are not eligible for relief from United States (net basis) income tax under the business profits article of an applicable income tax treaty, generally are exempt from the (gross basis) withholding tax described above. To obtain this exemption from withholding tax, the Non-U.S. Holder must provide the applicable withholding agent with an IRS Form W-8ECI or successor form or other applicable IRS Form W-8 certifying that the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States. Such effectively connected dividends, if not eligible for relief under the business profits article of a tax treaty, would not be subject to a withholding tax, but would be taxed at the same graduated rates applicable to U.S. persons, net of certain deductions and credits and if, in addition, the Non-U.S. Holder is a corporation, may also be subject to a branch profits tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty).

If you are eligible for a reduced rate of withholding tax pursuant to a tax treaty, you may be able to obtain a refund of any excess amounts currently withheld if you timely file an appropriate claim for refund with the IRS.

Gain on Sale or Other Disposition of Common Stock

Subject to the discussion below regarding backup withholding and FATCA, a Non-U.S. Holder generally will not be required to pay United States federal income tax on any gain realized upon the sale or other disposition of our common stock unless:

Backup Withholding and Information Reporting

Generally, we must file information returns annually to the IRS in connection with any dividends on our common stock paid to a Non-U.S. Holder, regardless of whether any tax was actually withheld. A similar report will be sent to the Non-U.S. Holder. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in the Non-U.S. Holder’s country of residence.

Payments of dividends or of proceeds on the disposition of stock made to a Non-U.S. Holder may be subject to additional information reporting and backup withholding at a current rate of 24% unless such Non-U.S. Holder establishes an exemption, for example by properly certifying its non-U.S. status on an IRS Form W-8BEN, IRS Form W-8BEN-E, IRS Form W-8ECI, or another appropriate version of IRS Form W-8 (or a successor form). Notwithstanding the foregoing, backup withholding and information reporting may apply if either we or our paying agent has actual knowledge, or reason to know, that a holder is a U.S. person.

Backup withholding is not an additional tax; rather, the U.S. income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may generally be obtained from the IRS, provided that the required information is furnished to the IRS in a timely manner.

Foreign Account Tax Compliance Act

FATCA imposes withholding tax on certain types of payments made to foreign financial institutions and certain other non-United States entities. The legislation imposes a 30% withholding tax on dividends on, or, on or after January 1, 2019, gross proceeds from the sale or other disposition of, our common stock paid to a “foreign financial institution” or to certain “non-financial foreign entities” (each as defined in the Code), unless (i) the foreign financial institution undertakes certain diligence and reporting obligations, (ii) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (i) above, it must enter into an agreement with the U.S. Treasury requiring, among other things, that it undertake to identify accounts held by “specified United States persons” or “United States-owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on payments to account holders whose actions prevent it from complying with these reporting and other requirements. If the country in which a payee is resident has entered into an “intergovernmental agreement” with the United States regarding FATCA, that agreement may permit the payee to report to that country rather than to the U.S. Department of the Treasury. Prospective investors should consult their own tax advisors regarding the possible impact of these rules on their investment in our common stock, and the possible impact of these rules on the entities through which they hold our common stock, including, without limitation, the process and deadlines for meeting the applicable requirements to prevent the imposition of this 30% withholding tax under FATCA.

Federal Estate Tax

Common stock owned (or treated as owned) by an individual who is not a citizen or a resident of the United States (as defined for United States federal estate tax purposes) at the time of death will be included in the individual’s gross estate for United States federal estate tax purposes unless an applicable estate or other tax treaty provides otherwise, and therefore may be subject to United States federal estate tax.

The preceding discussion of United States federal tax considerations is for general information only. It is not tax advice. Each prospective investor should consult its tax advisor regarding the particular United States federal, state and local and non-United States tax consequences of purchasing, holding and disposing of our common stock, including the consequences of any proposed change in applicable laws.

UNDERWRITING

We and the Underwriter intend to enter into an underwriting agreement with respect to the Shares, Series A Preferred Shares and Series B Preferred Shares being offered. Subject to certain conditions, pursuant to the Underwriter agrees to purchase the number of Shares, Series A Preferred Shares and Series B Preferred Shares indicated in the following table.

The underwriting agreement will provide that the obligations of the Underwriter to purchase the Shares, the Series A Preferred Shares and the Series B Preferred Shares included in this offering are subject to approval of legal matters by counsel and to other conditions. The Underwriter is obligated to purchase all of the Shares (other than those covered by the Underwriter’s over-allotment option to purchase additional Shares (described below)) if it purchases any of the Shares; all of the Series A Preferred Shares, if it purchases any of the Series A Preferred Shares; and all of the Series B Preferred Shares, if it purchases any of the Series B Preferred Shares.

Shares sold by the Underwriter to the public will initially be offered at the initial public offering price per Share of $ . The Series A Preferred Shares sold by the Underwriter to the public will initially be offered at an initial public offering price per Series A Preferred Share of $1,000. The Series B Preferred Shares sold by the Underwriter to the public will initially be offered at an initial public offering price per Series B Preferred Share of $1,000. Any Shares, Series A Preferred Shares or Series B Preferred Shares sold by the Underwriter to securities dealers may be sold at a discount from the initial public offering price not to exceed $ per Share, $ per Series A Preferred Share and $ per Series B Preferred Share. If all the Shares, Series A Preferred Shares and Series B Preferred Shares are not sold at their respective initial offering prices, the Underwriter may change the offering prices and the other selling terms in agreement with the Company.

Underwriting Discounts and Commissions

The following table shows the underwriting discounts and commissions that we are to pay to the Underwriter in connection with this offering, as well as the proceeds to us, before expenses. These amounts are shown assuming both no exercise and full exercise of the Underwriter’s over-allotment option to purchase additional shares of common stock.

We will also reimburse the Underwriter an aggregate of $135,000 for expenses incurred in this offering, including the reasonable fees and expenses of legal counsel.

We estimate that the total expenses of the offering payable by us, excluding underwriting discounts and commissions, will be approximately $643,991.

As additional compensation, we have agreed to issue the Underwriter or its designees, at the closing of this offering and any exercise of the Underwriter’s over-allotment option, as applicable, shares of our common stock equal to 2% of the aggregate Shares, shares of common stock issuable upon conversion of Series A Preferred Shares and Series B Preferred Shares sold in this offering, and any Shares issued upon exercise of the Underwriter’s over-allotment option, other than Shares, Series A Preferred Shares, Series B Preferred Shares, and any Shares issued upon exercise of the Underwriter’s over-allotment option, sold to certain investors who have a pre-existing relationship with us. Except as provided in Financial Industry Regulatory Authority, Inc. (“FINRA”) Rule 5110(g)(2), such shares have been deemed underwriting compensation by FINRA and shall not be sold, transferred, assigned, pledged, or hypothecated, or the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of such shares by any person for a period of 180 days immediately following the date of effectiveness or commencement of sales of this offering, pursuant to FINRA Rule 5110(g)(1). We have also granted the Underwriter the right to receive the compensation described above in connection with any future public or private offering or other capital raising transaction by us to investors (excluding certain pre-existing investors) that were “brought over the wall” by the Underwriter with our consent during the Underwriter’s sixty (60)-day engagement period that commenced on May 2, 2018, as long as such offering or capital raising transaction is consummated within the five (5)-month period following the introduction to such investors subsequent to April 25, 2018.

Over-Allotment Option to Purchase Additional Shares of Common Stock

If the Underwriter sells more shares than the total number set forth in the table above, we have granted to the Underwriter an over-allotment option, exercisable for forty-five (45) days from the date of this prospectus, to purchase up to 2,500,000 additional Shares of common stock at a price per share of $   , less the underwriting discount. The over-allotment option may be exercised by the Underwriter as to all (at any time) or any part (from time to time) of the option shares.

Indemnification

We intend to indemnify the Underwriter against certain liabilities, including liabilities under the Securities Act of, or to contribute to payments the Underwriter may be required to make because of any of those liabilities.

Lock-Ups

We, our officers and directors, and certain of our other stockholders intend to agree that, for a period of ninety (90) days from the date of this prospectus, we and they will not, subject to limited exceptions, without the prior written consent of the Underwriter, dispose of or hedge any shares or any securities convertible into or exchangeable for our common stock.

The NYSE American Listing

The Shares are listed on the NYSE American under the symbol “IBIO”.

On January 4, 2018, as a result of the Company’s then low per share price, the Company received notice from the NYSE American that it needed to effect a reverse stock split or otherwise demonstrate sustained improvement in its share price within a reasonable period of time in order to maintain its continued listing on the NYSE American.

To regain compliance with the NYSE American’s listing standards, the Company held a special meeting of its stockholders on April 23, 2018, at which the stockholders approved a proposal to effect an amendment its certificate of incorporation, as amended, to implement a reverse stock split at a ratio to be determined by the Board in a range not less than one-for-two (1:2) and not greater than one-for-ten (1:10). Our Board has determined to implement a reverse stock split at a ratio of one-for-ten (1:10) shares of the Company’s common stock. The reverse stock split became effective as of June 8, 2018.

On June 6, 2018, the Company received notice from the NYSE American that the Company currently is below the NYSE American’s continued listing standards set forth in 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 sustained losses from continuing operations and/or net losses in its five most recent fiscal years. The exchange indicated that a review of the Company shows that the Company is below compliance with Section 1003(a)(iii) since it reported stockholders’ equity of $4.2 million as of March 31, 2018 and net losses in its five most recent fiscal years.

The Company must submit a plan of compliance to the NYSE American by July 6, 2018 that explains how the Company intends to regain compliance with Section 1003(a)(iii) of the NYSE American Company Guide by December 6, 2019. If the Company does not submit a plan of compliance, or if the plan is not accepted by the NYSE American, the Company will be subject to delisting procedures as set forth in Section 1010 and Part 12 of the NYSE American Company Guide. If the plan is accepted by the NYSE American, the Company will be subject to periodic reviews including quarterly monitoring for compliance with the plan.

The Company believes it can provide the NYSE American with a satisfactory plan by July 6, 2018, to show that it will be able to return to compliance with Section 1003(a)(iii) of the NYSE American Company Guide by December 6, 2019.

The Company’s common stock will continue to be listed on the NYSE American while it attempts to regain compliance with the listing standards noted, subject to the Company’s compliance with other continued listing requirements. The Company’s common stock will continue to trade under the symbol “IBIO,” but will have an added designation of “.BC” to indicate that the Company is not in compliance with the NYSE American’s listing standards.

Expenses and Reimbursements

We estimate that our portion of the total expenses of this offering will be $50,000, excluding underwriting discounts, commissions and expenses of the underwriter that we have agreed to reimburse. We have agreed to reimburse the Underwriter $135,000 for expenses incurred in this offering, including expenses related to any filing with, and any clearance of this offering by, the Financial Industry Regulatory Authority, or FINRA.

Purchases and sales in the open market may include short sales, purchases to cover short positions, which may include purchases pursuant to the Underwriter’s over-allotment option to purchase additional shares, and stabilizing purchases.

Purchases to cover short positions and stabilizing purchases, as well as other purchases by the Underwriter for its own account, may have the effect of preventing or retarding a decline in the market price of our common stock. The Underwriter may also cause the price of our common stock to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The Underwriter may conduct these transactions on the NYSE American, in the over-the-counter market or otherwise. If the Underwriter commences any of these transactions, it may discontinue them at any time.

Passive Market Making

In connection with this offering, the Underwriting may also engage in passive market making transactions in the shares. Passive market making consists of displaying bids limited by the prices of independent market makers and effecting purchases limited by those prices in response to order flow. Rule 103 of Regulation M promulgated by the Securities and Exchange Commission limits the amount of net purchases that each passive market maker may make and the displayed size of each bid. Passive market making may stabilize the market price of the shares at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth the various expenses that will be paid by us in connection with the securities being registered. With the exception of the SEC registration fee, all amounts shown are estimates:

Our certificate of incorporation, as amended, will provide 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. We have entered into indemnification agreements with our officers and directors to specify the terms of our indemnification obligations. In general, these indemnification agreements provide that we will:

As permitted under Delaware law, our first amended and restated bylaws 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.

On June 8, 2018 the Company effected a 1 for 10 reverse stock split of its common stock. The number of shares and share prices in this Item 15 have been retroactively adjusted reflect the reverse split of our common stock as if it had occurred at the beginning of the earliest period presented.

The Lincoln Park Transaction

On July 24, 2017, the Company entered into a purchase agreement and a registration rights agreement with an institutional investor, Lincoln Park Capital Fund, LLC (“Lincoln Park”), an Illinois limited liability company, providing for the purchase of up to $16.0 million worth of the Company’s common stock, $0.001 par value per share, over the 36-month term of the purchase agreement. In connection therewith and as contemplated by the purchase agreement, on July 24, 2017, the Company sold 250,000 newly issued shares of its common stock, valued at $4.00 per share, to Lincoln Park for $1,000,000 in cash and issued 120,000 shares of its common stock to Lincoln Park pursuant to the terms of the purchase agreement as consideration for its commitment to purchase shares under the purchase agreement. The table below sets forth the additional sales of common stock made by the Company to Lincoln Park pursuant to the Purchase Agreement since July 24, 2017.

The Company may, from time to time and at its sole discretion, direct Lincoln Park to purchase shares of its common stock in amounts up to 10,000 shares on any single business day, subject to a maximum of $1,000,000 per purchase, plus other “accelerated amounts” and/or “additional amounts” under certain circumstances. There are no trading volume requirements or restrictions under the purchase agreement, and the Company will control the timing and amount of any sales of its common stock to Lincoln Park. The purchase price of the shares that may be sold to Lincoln Park under the purchase agreement will be based on the market price of the Company’s common stock preceding the time of sale as computed under the purchase agreement. The purchase price per share will be equitably adjusted for any reorganization, recapitalization, non-cash dividend, stock split, or other similar transaction occurring during the business days used to compute such price. The Company may at any time in its sole discretion terminate the purchase agreement without fee, penalty or cost upon one business day notice. There are no restrictions on future financings, rights of first refusal, participation rights, penalties or liquidated damages in the purchase agreement or the registration rights agreement entered into in connection with the purchase agreement other than a prohibition on entering into a “Variable Rate Transaction,” as defined in the purchase agreement.

Lincoln Park represented to the Company, among other things, that it was an “accredited investor” (as such term is defined in Rule 501(a) of Regulation D under the Securities Act), and the Company sold the securities in reliance upon an exemption from registration contained in Section 4(a)(2) of the Securities Act and Regulation D promulgated thereunder.

Exhibits filed with this Registration Statement on Form S-1 or incorporated by reference from other filings are as follows:

(a) We hereby undertake:

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

(b) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
