To the extent applicable, the information in Item 8.01 of this Form 8-K is incorporated by reference into this Item 5.08.

The Board of Directors of iBio, Inc., a Delaware corporation (the “Company”) has established Tuesday, December 19, 2017 as the date of the Company’s 2017 Annual Meeting of Stockholders (the “2017 Annual Meeting”). Because the date of the 2017 Annual Meeting has advanced by more than 30 days from the anniversary date of the Company’s 2016 Annual Meeting of Stockholders (the “2016 Annual Meeting”), in accordance with Rule 14a−5(f) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company is informing stockholders of such change.

Stockholders of record at the close of business on November 16, 2017 will be entitled to vote at the 2017 Annual Meeting. The time and location of the 2017 Annual Meeting will be as set forth in the Company’s proxy statement for the 2017 Annual Meeting. Because the date of the 2017 Annual Meeting has been changed by more than 30 days from the anniversary of the 2016 Annual Meeting, a new deadline has been set for submission of proposals by stockholders of the Company intended to be included in the Company’s 2017 proxy statement and form of proxy for its 2017 Annual Meeting.

Stockholders of the Company who wish to have a proposal considered for inclusion in the Company’s proxy materials for the 2017 Annual Meeting pursuant to Rule 14a-8 under the Exchange Act, must ensure that such proposal is received by the Company’s Secretary, at 600 Madison Avenue, Suite 1601, New York, NY 10022, on or before the close of business on November 2, 2017, which the Company has determined to be a reasonable time before it expects to begin to print and send its proxy materials. Any such proposal must also meet the requirements set forth in the rules and regulations of the Securities and Exchange Commission in order to be eligible for inclusion in the proxy materials for the 2017 Annual Meeting. The November 2, 2017 deadline also will apply in determining whether notice of a shareholder proposal is timely for purposes of exercising discretionary voting authority with respect to proxies under Rule 14a-4(c) of the Exchange Act.

In addition, in accordance with the requirements contained in the Company’s Bylaws, stockholders of the Company who wish to bring business before the 2017 Annual Meeting outside of Rule 14a-8 of the Exchange Act or to nominate a person for election as a director must ensure that written notice of such proposal (including all of the information specified in the Company’s Bylaws) is received by the Company’s Secretary at the address specified above no later than the close of business on November 2, 2017. Any such proposal must meet the requirements set forth in the Company’s Bylaws in order to be brought before the 2017 Annual Meeting.
