PROXY STATEMENT

FOR THE 2016 ANNUAL MEETING OF STOCKHOLDERS

PROXY AND VOTING

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS:

The notice of annual meeting of stockholders, the proxy statement and the Company’s Annual Report on Form 10-K for the year ended June 30, 2016 are available electronically to the Company’s stockholders of record as of the close of business on April 3, 2017 at [http://www.cstproxy.com/ibioinc/2017/.]

QUESTIONS AND ANSWERS ABOUT THIS PROXY STATEMENT AND VOTING

Q. Why am I receiving this proxy statement?

Stockholder of Record: Shares Registered in Your Name -- If on the Record Date your shares of common stock were registered directly in your name with our transfer agent, Continental Stock Transfer and Trust Company, then you are a stockholder of record. As a stockholder of record, you may vote in person at the annual meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to vote by returning the enclosed proxy card to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank -- If on the Record Date your shares of common stock were held in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker, bank or other agent regarding how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy from your broker, bank or other agent.

Your shares will be counted towards the quorum only if you submit a valid proxy vote or vote at the annual meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of the shares present in person or represented by proxy at the annual meeting may adjourn the meeting to another date.

A. There are three matters scheduled for a vote:

As of the date of this proxy statement, we are not aware of any business expected to come before or be transacted at the annual meeting other than the matters described above.

Q. How do I vote?

Stockholder of Record: Shares Registered in Your Name -- If you are a stockholder of record, you may vote in person at the annual meeting or you can vote by returning the enclosed proxy card. Whether or not you plan to attend the annual meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the annual meeting and vote in person even if you have already voted by proxy.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or other agent -- If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received this proxy statement from that organization rather than from iBio. Simply follow the voting instructions provided by that organization. To vote in person at the annual meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker, bank or other agent included with these proxy materials, or contact your broker, bank or other agent to request a proxy form.

In their discretion on any other matters that properly come before the annual meeting.

If your shares are held by your broker as your nominee (that is, in “street name”), you will need to obtain a proxy form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your broker to vote your shares. If you do not give instructions to your broker, your broker can vote your shares with respect to “discretionary” items, but not with respect to “non-discretionary” items. On non-discretionary items for which you do not give your broker instructions, the shares will be treated as broker non-votes. The ratification of the selection of CohnReznick LLP is a “discretionary” item. All the other matters being acted upon and put to a vote at the annual meeting are “non-discretionary” items.

To be approved, Proposals 2 and 3 (ratifying the selection of CohnReznick LLP as our independent registered public accounting firm for the fiscal year ending June 30, 2017 and approving the “say on pay” proposal) must receive “FOR” votes from the holders of a majority of shares present at the annual meeting, either in person or by proxy. Abstentions and broker non-votes will have the same effect as a vote against the proposal, because passage of Proposals 2 and 3 requires the affirmative vote of a majority of the votes present, in person or by proxy, at the annual meeting.

PROPOSAL 1 -- ELECTION OF DIRECTORS

The Company’s board of directors is currently composed of seven (7) directors divided into three classes of directors, Class I, II and III, with each class serving staggered 3-year terms. The current term of office for each Class II director expires at the annual meeting. The class and current term of each director is as follows:

At our annual meeting, our stockholders will consider and vote upon the re-election of Glenn Chang and Philip K Russell, M.D. to serve as Class II directors. If re-elected, these nominees will serve for a three year term that will expire at the 2019 annual meeting of stockholders. Our board of directors believes that all of our current directors, including the two nominees for election, possess personal and professional integrity, good judgment, a high level of ability and business acumen. Our board of directors also believes that Mr. Chang and Dr. Russell have performed exceptionally well in their respective time served as directors.

Each nominee has agreed to serve if elected and we have no reason to believe that any nominee will be unable to serve. If any nominee becomes unavailable for election as a result of an unexpected occurrence, proxies will be voted for the election of a substitute nominee proposed by our board of directors or for election of only the remaining nominees.

Unless authority to do so is withheld, shares represented by executed proxies will be voted for the election of Mr. Chang and Dr. Russell. Proxies cannot be voted for a greater number of persons than the number of nominees standing for election. Since two directors are to be elected at the annual meeting, the two nominees for director who receive the highest number of affirmative votes for election will be elected as Class II directors.

Information with respect to the number of shares of common stock beneficially owned by each nominee for election as a Class II director and each of our other directors appears under the heading “Security Ownership of Certain Beneficial Owners and Management”.

The name, age, years of service on our board of directors, principal occupation and business experience and certain other information for each Class II director nominee is set forth below.

The board of directors believes that approval of the election of each nominee director named above is in the best interests of our stockholders and therefore recommends a vote “FOR” each nominee.

OTHER DIRECTORS OF THE COMPANY SERVING AS CLASS I AND CLASS III DIRECTORS

The name, age, years of service on our board of directors, principal occupation and business experience and certain other information for each our Class I and Class III directors who will continue to serve on the board of directors and who are not standing for election at this annual meeting is set forth below:

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE 
GOVERNANCE

Director Compensation

Compensation for our non-employee directors has historically consisted of a grant of stock options vesting over a three-year period and additional cash compensation. We do not have a fixed policy with respect to this compensation, but the compensation is generally equal for each non-employee director except in cases where a director assumes additional responsibilities above and beyond standard board service. Directors who are also our employees receive no additional compensation for their services as directors.

Director Compensation Table

The following table sets forth summary information concerning the total compensation paid to our non-employee directors for services to the Company during the fiscal year ended June 30, 2016:

Director Independence

Our board of directors has determined that Messrs. Chang, Flug and McKey, Drs. Elliott and Russell and General Hill are each “independent directors” as such term is defined in Section 803 of the New York Stock Exchange MKT Company Guide.

Board Committees

Our board of directors has the authority to appoint committees to perform certain management and administrative functions. Our board of directors has constituted audit, compensation and nominating committees.

Nominating Committee and Nomination Process

The Nominating Committee was formed to address general governance and policy oversight; succession planning; to identify qualified individuals to become prospective board members and make recommendations regarding nominations for our board of directors; to advise the board with respect to appropriate composition of board committees; to advise the board about and develop and recommend to the board appropriate corporate governance documents and assist the board in implementing guidelines; to oversee the annual evaluation of the board and our chief executive officer, and to perform such other functions as the board may assign to the committee from time to time. The Nominating Committee has a charter which is available on our website at www.ibioinc.com.  The Nominating Committee consists of three independent directors: Arthur Y. Elliott, Ph.D., (Nominating Committee Chairman), Glenn Chang and General James T. Hill.

Our directors take a critical role in guiding our strategic direction and oversee the management of our company. Board candidates are considered based upon various criteria, such as their broad-based business and professional skills and experiences, a global business and social perspective, concern for the long-term interests of our stockholders and personal integrity and judgment. In addition, directors must have time available to devote to board activities and to enhance their knowledge of the life sciences industry. Accordingly, we seek to attract and retain highly qualified directors who have sufficient time to attend to their substantial duties and responsibilities.

Our board of directors believes given the diverse skills and experience required to grow our company that the input of all members of the Nominating Committee is important for considering the qualifications of individuals to serve as directors but does not have a diversity policy. Further, the Nominating Committee believes that the minimum qualifications for serving as our director are that a nominee demonstrate, by significant accomplishment in his or her field, an ability to make a meaningful contribution to the board’s oversight of our business and affairs of and have an impeccable record and reputation for honest and ethical conduct in both his or her professional and personal activities. Whenever a new seat or a vacated seat on the board is being filled, candidates that appear to best fit the needs of the board and our company are identified and unless such individuals are well known to the board, they are interviewed and further evaluated by the Nominating Committee.  Candidates selected by the Nominating Committee are then recommended to the full board for their nomination to stockholders. The Nominating Committee recommends a slate of directors for election at the annual meeting. In accordance with NYSE MKT LLC rules, the slate of nominees is approved by a majority of the independent directors.

In carrying out its responsibilities, our board will consider candidates suggested by stockholders. If a stockholder wishes to formally place a candidate’s name in nomination, however, he or she must do so in accordance with the provisions of our First Amended and Restated Bylaws. Suggestions for candidates to be evaluated by the Nominating Committee must be sent to Secretary, iBio, Inc., 600 Madison Avenue, Suite 1601, New York, NY 10022-1737.

Audit Committee

The Audit Committee of the board of directors makes recommendations regarding the retention of the independent registered public accounting firm, reviews the scope of the annual audit undertaken by our independent registered public accounting firm and the progress and results of their work, reviews our financial statements, and oversees the internal controls over financial reporting and corporate programs to ensure compliance with applicable laws and regulations. The Audit Committee reviews all services performed for us by the independent registered public accounting firm and determines whether they are compatible with maintaining the registered public accounting firm’s independence. The Audit Committee has a charter, which is reviewed annually and as may be required due to changes in industry accounting practices or the promulgation of new rules or guidance documents. The Audit Committee charter is available on our website at www.ibioinc.com. The Audit Committee consists of two independent directors as determined by NYSE MKT LLC listing standards: Glenn Chang (Audit Committee Chairman) and Seymour Flug. Mr. Chang and Mr. Flug are each qualified as an Audit Committee Financial Expert as defined in Regulation S-K Item 407(d)(5)(ii).

Compensation Committee

The Compensation Committee of the Board of Directors reviews and approves executive compensation policies and practices, reviews salaries and bonuses for our senior executive officers, administers our equity incentive plan and other benefit plans, and considers other matters as may, from time to time, be referred to them by our board of directors.  The Compensation Committee has a charter which is available on our website at www.ibioinc.com.  The members of the Compensation Committee are General James T. Hill (Compensation Committee Chairman), Arthur Y. Elliott, Ph.D. and Philip K. Russell, M.D.

Board Leadership Structure and Role in Risk Oversight

Our chief executive officer also serves as the executive chairman of our board of directors. We do not have a lead independent director. Our executive chairman, when present, presides over all meetings of our board. We believe this leadership structure is appropriate for our Company at this time because (1) of our size, (2) of the size of our board, (3) our chief executive officer is responsible for our day-to-day operation and implementing our strategy, and (4) discussion of developments in our business and financial condition and results of operations are important parts of the discussion at meetings of our board of directors and it makes sense for our chief executive officer to chair those discussions.

Our board of directors oversees our risk management. This oversight is administered primarily through the following:

Meetings of the Board of Directors and Committees

During the fiscal year ended June 30, 2016, the board of directors held two meetings in person or by telephone and acted by unanimous written consent on one occasion and the Audit Committee held four meetings in person or by telephone. No meetings in person or by telephone were held and no actions were taken by either the Nominating Committee or Compensation Committee as matters addressable by such committees were considered and approved by the full board. Between meetings, members of the board of the directors are provided with information regarding our operations and are consulted on an informal basis with respect to pending business. Each director attended at least 75% of the aggregate of the total number of meetings of the board and the total number of meetings of the committees on which such director serves. All of our directors attended our 2015 Annual Meeting of Stockholders.

Although we do not have a policy with regard to board members’ attendance at our annual meetings of stockholders, all of the directors are encouraged to attend such meetings.

Stockholder Communications with the Board of Directors

Interested parties may communicate with the board or specific members of the board, including the independent directors and the members of the Audit Committee, by submitting correspondence addressed to the Board of Directors of iBio, Inc. c/o any specified individual director or directors at 600 Madison Avenue, Suite 1601, New York, New York 10022-1737. Any such correspondence will be forwarded to the indicated directors.

Code of Ethics

We have adopted a written code of ethics within the meaning of Item 406 of SEC Regulation S-K, which applies to all of our employees, including our principal executive officer and our chief financial officer, a copy of which can be found on our website at www.ibioinc.com. If we make any waivers or substantive amendments to the code of ethics that are applicable to our principal executive officer or our chief financial officer, we will disclose the nature of such waiver or amendment in a Current Report on Form 8-K in a timely manner. No waivers from any provision of our policy have been granted.

The policy our board of directors is to review with management and our independent registered public accounting firm any related party transactions brought to the board’s attention which could reasonably be expected to have a material impact on our financial statements.

In addition, transactions involving our directors and their affiliated entities were disclosed and reviewed by our board of directors in its assessment of our directors’ independence requirements.

Transactions with Eastern Capital Limited and its Affiliates

On January 13, 2016, we entered into a share purchase agreement with Eastern Capital Limited (“Eastern”), our largest stockholder, which was amended as of February 25, 2016 (as amended, the “6.5M Purchase Agreement”). Pursuant to the 6.5M Purchase Agreement, Eastern agreed to purchase 6,500,000 shares of our common stock (the “Eastern Shares”), for a purchase price of $0.622 per share, subject to the approval of our stockholders. Our stockholders approved the issuance of such shares at our 2015 Annual Meeting.

On the same day that we entered into the 6.5M Purchase Agreement, we also entered into a separate share purchase agreement pursuant to which Eastern agreed to purchase 3,500,000 shares of our common stock (the “3.5M Purchase Agreement”) for a purchase price of $0.622 per share (the “3.5M Purchase Agreement” and together with the 6.5M Purchase Agreement, the “Purchase Agreements”). Stockholder approval was not required for the issuance of the 3,500,000 shares of our common stock pursuant to the 3.5M Purchase Agreement and the sale of those shares was completed on January 25, 2016.

Simultaneously with the issuance of shares under the 3.5M Purchase Agreement, Eastern exercised warrants, dated April 26, 2013, which Eastern acquired previously, to purchase 1,784,000 shares of common stock for a purchase price of $0.53 per share.

Concurrently with the execution of the Purchase Agreements, we entered into a contract manufacturing joint venture with affiliates of Eastern to develop and manufacture plant-made pharmaceuticals through iBio’s recently formed subsidiary, iBio CMO LLC (“iBio CMO”). Bryan Capital Investors LLC (“Bryan Capital Investors”), an affiliate of Eastern, contributed $15.0 million in cash to iBio CMO, for a 30% interest in iBio CMO. iBio retained a 70% equity interest in iBio CMO. iBio contributed to the capital of iBio CMO a royalty bearing license, which grants iBio CMO a non-exclusive license to use the iBio’s proprietary technology, including the iBioLaunch technology, for research purposes and an exclusive U.S. license for manufacturing purposes. iBio retains all other rights in its intellectual property, including the rights to commercialize products based on its proprietary technology. On February 23, 2017, we entered into an Exchange Agreement with Bryan Capital Investors, pursuant to which we issued to Bryan Capital Investors one share of our iBio CMO Preferred Tracking Stock, par value $0.001 per share, in exchange for 29,990,000 units of limited liability company interests of iBio CMO held by Bryan Capital Investors. After giving effect to the transactions contemplated in the Exchange Agreement, we own 99.99% of iBio CMO and Bryan Capital Investors owns 0.01% of iBio CMO. iBio has the right to appoint a majority of the members of the Board of Managers that manages the iBio CMO joint venture. Specified material actions by the joint venture require the consent of iBio and Bryan Capital Investors.

In connection with the joint venture, an affiliate of Eastern (the “Eastern Affiliate”), which controls the subject property as sublandlord, granted iBio CMO a 34-year sublease of a 139,000 square foot Class A life sciences building in Bryan, Texas on the campus of Texas A&M University, designed and equipped for plant-made manufacture of biopharmaceuticals. iBio CMO began operations at the facility on December 22, 2015 pursuant to agreements between iBio CMO and the Eastern Affiliate granting iBio CMO temporary rights to access the facility. These temporary agreements were superseded by the Sublease Agreement, dated January 13, 2016, between iBio CMO and the Eastern Affiliate (the “Sublease”). The 34-year term of the Sublease may be extended by iBio CMO for a ten-year period, so long as iBio CMO is not in default under the Sublease. Under the Sublease, iBio CMO is required to pay base rent at an annual rate of $2,100,000, paid in equal quarterly installments on the first day of each February, May, August and November. The base rent is subject to increase annually in accordance with increases in the Consumer Price Index. The base rent under the Eastern Affiliate’s ground lease for the property is subject to adjustment, based on an appraisal of the property, in 2030 and upon any extension of the ground lease. The base rent under the Sublease will be increased by any increase in the base rent under the ground lease as a result of such adjustments. In addition to the base rent, iBio CMO is required to pay, for each calendar year during the term, a portion of the total gross sales for products manufactured or processed at the facility, equal to 7% of the first $5,000,000 of gross sales, 6% of gross sales between $5,000,001 and $25,000,000, 5% of gross sales between $25,000,001 and $50,000,000, 4% of gross sales between $50,000,001 and $100,000,000, and 3% of gross sales between $100,000,001 and $500,000,000. However, if for any calendar year period from January 1, 2018 through December 31, 2019, iBio CMO’s applicable gross sales are less than $5,000,000, or for any calendar year period from and after January 1, 2020, its applicable gross sales are less than $10,000,000, then iBio CMO is required to pay the amount that would have been payable if it had achieved such minimum gross sales and shall pay no less than the applicable percentage for the minimum gross sales for each subsequent calendar year. iBio CMO is responsible for all costs and expenses in connection with the ownership, management, operation, replacement, maintenance and repair of the property under the Sublease. General and administrative expenses related to the Eastern Affiliate were approximately $565,000 in 2016. Interest expense incurred under the capital lease obligation amounted to $807,000 in 2016.

As part of the transactions between Eastern and the Company, Eastern entered into a three year standstill agreement (the “Standstill Agreement”) that restricts additional acquisitions of our common stock by Eastern and its controlled affiliates to limit its beneficial ownership of our outstanding shares of common stock to a maximum of 38%, absent approval by a majority of our Board of Directors. With respect to the Standstill Agreement, our Board of Directors, acting unanimously, invited Bryan Capital Investors to enter into the Exchange Agreement described above and approved the issuance of one share of our Preferred Tracking Stock to Bryan Capital Investors.

Eastern does not have a right to appoint a director designee or any other special rights with respect to our management and affairs aside from its ability to vote the shares of common stock that it owns as it determines. Eastern has not been granted any board, management or special voting rights in connection with the transactions contemplated in the Purchase Agreements.

Research and Development Services Vendor

In January 2012, the Company entered into an agreement with Novici Biotech, LLC (“Novici”) in which iBio’s President is a minority stockholder. Novici performs platform technology development services for iBio, including laboratory feasibility analyses of gene expression, protein purification and preparation of research samples. The transaction has been conducted on an arm’s length basis at market terms. The accounts payable balance includes amounts due to Novici of approximately $200,000 and $153,000 at June 30, 2016 and 2015, respectively. Research and development expenses related to Novici were approximately $1,036,000 and $995,000 for the years ended June 30, 2016 and 2015, respectively.

Operating Lease with Minority Stockholder

Effective January 1, 2015, the Company is leasing office space on a month-to-month basis from an entity owned by a minority stockholder of the Company for approximately $7,500 per month.

Limitation of Liability of Officers and Directors and Indemnification

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

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

Historical Relationship with Integrated BioPharma, Inc.

We were a subsidiary of Integrated BioPharma, Inc. (“Integrated BioPharma”) from February 21, 2003 until August 18, 2008. On that date, Integrated BioPharma spun off iBio in a transaction that was intended to be a tax free distribution to Integrated BioPharma and its U.S. stockholders. As part of that transaction, we entered into a number of agreements with Integrated BioPharma including an indemnification and insurance matters agreement and a tax responsibility allocation agreement. Messrs. E. Gerald Kay and Carl DeSantis, affiliates of Integrated BioPharma, were in 2008 and continue to remain beneficial holders of more than 5% of our common stock. The agreements are described below.

Indemnification. In general, under the indemnification and insurance matters agreement, we agreed to indemnify Integrated BioPharma, its affiliates and each of its and their respective directors, officers, employees, agents and representatives from all liabilities that arise from:

Integrated BioPharma agreed to indemnify us and our affiliates and our directors, officers, employees, agents and representatives from all liabilities that arise from:

Integrated BioPharma is not obligated to indemnify us against any liability for which we are also obligated to indemnify Integrated BioPharma. Recoveries by Integrated BioPharma under insurance policies will reduce the amount of indemnification due from us to Integrated BioPharma only if the recoveries are under insurance policies Integrated BioPharma maintains for our benefit. Recoveries by us will in all cases reduce the amount of any indemnification due from Integrated BioPharma to us.

Under the indemnification and insurance matters agreement, a party has the right to control the defense of third-party claims for which it is obligated to provide indemnification, except that Integrated BioPharma has the right to control the defense of any third-party claim or series of related third- party claims in which it is named as a party whether or not it is obligated to provide indemnification in connection with the claim and any third-party claim for which Integrated BioPharma and we may both be obligated to provide indemnification. We may not assume the control of the defense of any claim unless we acknowledge that if the claim is adversely determined, we will indemnify Integrated BioPharma in respect of all liabilities relating to that claim. The indemnification and insurance matters agreement does not apply to taxes covered by the tax responsibility allocation agreement.

Offset. Integrated BioPharma is permitted to reduce amounts it owes us under any of our agreements with Integrated BioPharma, by amounts we may owe to Integrated BioPharma under those agreements.

Assignment. We may not assign or transfer any part of the indemnification and insurance agreement without Integrated BioPharma’s prior written consent. Nothing contained in the agreement restricts the transfer of the agreement by Integrated BioPharma.

Tax Responsibility Allocation Agreement

In order to allocate our responsibilities for taxes and certain other tax matters, we and Integrated BioPharma entered into a tax responsibility allocation agreement prior to the date of the distribution. Under the terms of the agreement, with respect to consolidated federal income taxes, and consolidated, combined and unitary state income taxes, Integrated BioPharma will be responsible for, and will indemnify and hold us harmless from, any liability for income taxes with respect to taxable periods or portions of periods ending prior to the date of distribution to the extent these amounts exceed the amounts we have paid to Integrated BioPharma prior to the distribution or in connection with the filing of relevant tax returns. Integrated BioPharma is also responsible for, and will indemnify and hold us harmless from, any liability for income taxes of Integrated BioPharma or any member of the Integrated BioPharma group (other than us) by reason of our being severally liable for those taxes under U.S. Treasury regulations or analogous state or local provisions. Under the terms of the agreement, with respect to consolidated federal income taxes, and consolidated, combined and unitary state income taxes, we are responsible for, and will indemnify and hold Integrated BioPharma harmless from, any liability for our income taxes for all taxable periods, whether before or after the distribution date. With respect to separate state income taxes, we are also responsible for, and will indemnify and hold Integrated BioPharma harmless from, any liability for income taxes with respect to taxable periods or portions of periods beginning on or after the distribution date. We are also responsible for, and will indemnify and hold Integrated BioPharma harmless from, any liability for our non-income taxes and our breach of any obligation or covenant under the terms of the tax responsibility allocation agreement, and in certain other circumstances as provided therein. In addition to the allocation of liability for our taxes, the terms of the agreement also provide for other tax matters, including tax refunds, returns and audits.

PROPOSAL 2 -- RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board of Directors has selected CohnReznick LLP as our independent registered public accounting firm for the fiscal year ending June 30, 2017 and has further directed that management submit the selection of the independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. CohnReznick LLP was engaged as our principal accounting firm in October 2009. Representatives of CohnReznick LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our Bylaws nor other governing documents or law require stockholder ratification of the selection of CohnReznick LLP as our independent registered public accounting firm. However, the Audit Committee of the Board is submitting the selection of CohnReznick LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in our company’s and our stockholders’ best interests.

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the annual meeting will be required to ratify the selection of CohnReznick LLP. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

The board of directors believes that the selection of CohnReznick LLP as our independent registered public accounting firm for the fiscal year ending June 30, 2017 is in our best interest and the best interests of our stockholders and therefore recommends a vote “FOR” this proposal.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS*

The Audit Committee has prepared the following report on its activities with respect to our audited financial statements for the year ended June 30, 2016.

Our management is responsible for the preparation, presentation and integrity of our financial statements and is also responsible for maintaining appropriate accounting and financial reporting practices and policies. Management is also responsible for establishing and maintaining adequate internal controls and procedures designed to provide reasonable assurance that we are in compliance with accounting standards and applicable laws and regulations.

CohnReznick LLP, our independent registered public accounting firm for the year ended June 30, 2016, is responsible for expressing opinions on the conformity of our audited financial statements with accounting principles generally accepted in the United States.

The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended June 30, 2016 with our management. The Audit Committee has discussed with our independent registered public accounting firm the matters required to be discussed by the Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board (“PCAOB”) in Rule 3200T. The Audit Committee has also received the written disclosures and the letter from our independent registered public accounting firm required by the Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), as adopted by the PCAOB in Rule 3600T and has discussed with our independent registered public accounting firm the firm’s independence.

The following table represents aggregate fees billed to us by CohnReznick LLP:

In the above table, in accordance with the SEC’s definitions and rules, “audit fees” are fees we paid CohnReznick LLP for professional services for the audit of our financial statements included in our Annual Reports on Form 10-K, review of our financial statements included in our Quarterly Reports on Form 10-Q and services normally provided in connection with statutory and regulatory filings or engagements, consents and assistance with and review of our documents filed with the SEC.

Pre-Approval Policies and Procedures

The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services. Pre-approval is generally detailed as to the particular service or category of services and is generally subject to a specific budget. The independent registered public accounting firm and management are required to periodically report to the audit committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, and the fees for the services performed to date. The Audit Committee may also pre-approve particular services on a case-by-case basis. The Audit Committee has determined that the rendering of the services other than audit services by CohnReznick LLP is compatible with maintaining the principal accountant’s independence.

Based on the foregoing, the Audit Committee has recommended to the board of directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2016 and selected CohnReznick LLP as our independent registered public accounting firm for the fiscal year ending June 30, 2017.

PROPOSAL 3 -- ADVISORY VOTE ON COMPENSATION OF EXECUTIVE OFFICERS

(“SAY-ON-PAY”)

Background of Proposal

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) and related SEC rules require that we provide our stockholders with the opportunity to vote to approve, on a nonbinding, advisory basis, the compensation of our named executive officers as disclosed in this proxy statement.

As previously reported, in an advisory vote on the frequency of the advisory vote on the compensation of our named executive officers held at our 2013 Annual Meeting of Shareholders held on December 17, 2013, 23,434,027 shares voted for one year, 175,679 shares voted for two years, 14,494,461 shares voted for three years, and there were 61,561 abstentions and 17,653,046 broker non-votes.

SEC regulations state that we must hold these votes on frequency at least once every six years. In light of these voting results and other factors, our Board of Directors decided that we will hold an annual advisory vote on the compensation of our named executive officers. We will continue to hold annual advisory votes until our Board of Directors decides to hold the next shareholder advisory vote on the frequency of advisory votes. 

Our executive compensation program is designed to align the interests of our stockholders and our executive officers. We use our executive compensation programs to attract, motivate, and retain our executive officers and to ensure that their efforts focus on the long term performance of iBio. These officers are critical to the achievement of our current and longer term strategic and financial performance goals and objectives.

Our executive compensation program is comprised of cash compensation, in the form of fixed salary, and equity-based compensation. In addition, we provide our executive officers with benefits that are generally available to our salaried employees. We believe that offering our executive officers differing forms of compensation allows us to achieve varied objectives.

Cash compensation, for example, provides our executive officers with a guaranteed minimum base salary. We fix the base salary of each of our executive officers at a level that we believe enables us to hire and retain individuals in a competitive environment and reward individual performance and contribution to our overall business goals.  

Our equity based compensation is effected through a stock option program. This is the primary means of linking our named executive officers’ compensation and the long-term performance of iBio. The stock option program encourages a long-term focus from our executives by using a multi-year minimum vesting requirement for stock options and creates an ownership culture that helps unify the interests of our executives and stockholders.

As noted above, we view the components of our executive officer compensation as related but distinct. Although our board of directors does review total compensation, it does not believe that compensation derived from one component of compensation should negate or reduce compensation from other components. Neither our board of directors nor our Compensation Committee has adopted any formal or informal policies or guidelines for allocating compensation between long-term and currently paid out compensation, between cash and equity based compensation, or among different forms of compensation. This is due to the small size of our executive officer team and the need to tailor each executive officer’s award to attract and retain that executive officer.

Additional details about our executive compensation program, including information about compensation for our named executive officers for the fiscal year ended June 30, 2016, are described under the “Executive Compensation” section of this proxy statement.

We are asking our stockholders to indicate their support for our executive officer compensation as described in this proxy statement. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on the compensation of our executive officers. This vote is not intended to address any specific item of compensation, but rather to evaluate the overall compensation of our executive officers and the philosophy, policies and practices described in this proxy statement. Accordingly, the following resolution is submitted for a vote by our stockholders at the annual meeting:

“RESOLVED, that the stockholders of iBio, Inc. hereby APPROVE, on an advisory basis, the compensation paid to its named executive officers, as disclosed in the Proxy Statement for the 2016 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the SEC, including the compensation tables and the narrative discussion that accompany the compensation tables.”

This say-on-pay vote is advisory, and therefore not binding on us, the Compensation Committee or our board of directors. However, our board and our Compensation Committee value the opinion of our stockholders and will consider our stockholders’ opinion when making future compensation decisions for our named executive officers.

Our board of directors recommends that stockholders vote to approve the compensation of our named executive officers by voting “FOR” Proposal 3.

OTHER INFORMATION

Other Matters

Our board of directors knows of no other matters that will be presented for consideration at the annual meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote, or otherwise act, on such matters in accordance with their judgment.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the 1934 Exchange Act requires our directors and executive officers, and persons who own more than ten percent of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. Officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations that no other reports were required, during the fiscal year ended June 30, 2016, all Section 16(a) filing requirements applicable to our officers, directors and greater than ten percent beneficial owners were complied with, except the following reports were not filed on a timely basis: (1) Statements of Changes in Beneficial Ownership on Form 4 reporting grants of stock options made on September 5, 2014 to purchase 60,000 shares of our common stock and grants of stock options made on September 4, 2015 to purchase 100,000 shares of our common stock made to each of Philip K Russell, M.D., Arthur Y. Elliott, Ph.D., Glenn Chang, John D. McKey, Jr., Seymour Flug and General James T. Hill, which were filed on April 5, 2017, (2) a Statement of Changes in Beneficial Ownership on Form 4 reporting a grant of stock options made on September 4, 2015 to purchase 100,000 shares of our common stock made to Terence Ryan, Ph.D., which was filed on April 5, 2017, (3) Statements of Changes in Beneficial Ownership on Form 4 reporting a grant of stock options made on September 5, 2014 to purchase 600,000 shares of our common stock and a grant of stock options made on September 4, 2015 to purchase 750,000 made to Robert Erwin, which were filed on April 5, 2017, (4) Statements of Changes in Beneficial Ownership on Form 4 reporting a grant of stock options made on September 5, 2014 to purchase 600,000 shares of our common stock and a grant of stock options made on September 4, 2015 to purchase 750,000 made to Robert B. Kay, which were filed on April 5, 2017, and (5) Statements of Changes in Beneficial Ownership on Form 4 reporting a grant of stock options made on September 5, 2014 to purchase 50,000 shares of our common stock and a grant of stock options made on September 4, 2015 to purchase 150,000 made to Mark A. Giannone, which were filed on April 5, 2017.

Stockholder Proposals for the 2017 Annual Meeting

Rules of the SEC require that we receive any proposal by our stockholders for inclusion in our proxy materials for the 2017 annual meeting of stockholders no later than by December 7, 2017. Proposals must be submitted in writing to us c/o Secretary, iBio, Inc., 600 Madison Avenue, Suite 1601, New York, NY 10022, and you must comply with other requirements of Rule 14a-8 under the 1934 Exchange Act. However, if the 2017 annual meeting date changes by more than 30 days from the date of the 2016 annual meeting date, then the proposal must be submitted a reasonable time before we begin to print and send our proxy materials for the 2017 annual meeting.

In addition, our First Amended and Restated Bylaws have an advance notice procedure for stockholders to bring business before an annual meeting of stockholders. The advance notice procedure requires that a stockholder interested in presenting a proposal for action at the 2017 annual meeting of stockholders must deliver a written notice of the proposal, together with specific information relating to such stockholder’s proposal, nominee, stock ownership and identity, to our corporate secretary no later than the close of business on February 2, 2018 and no earlier than the close of business on January 3, 2018. You are advised to review our bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations. You must comply with these bylaws requirements in connection with a stockholder proposal or director nomination outside the Rule 14a-8 context.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are our stockholders will be “householding” our proxy materials. A single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent.

If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate proxy statement and annual report, please notify your broker, direct your written request to iBio, Inc., Attention: Secretary, 600 Madison Avenue, Suite 1601, New York, NY 10022 or contact our Corporate Secretary at (302) 355-0650. Stockholders who currently receive multiple copies of the proxy statement at their address and would like to request “householding” of their communications should contact their broker.
