On November 30, 2017, iBio, Inc., a Delaware corporation (the “Company”), closed its previously announced public offering of 22,500,000 shares of its common stock at a public offering price of $0.20 per share.

The shares of common stock were issued pursuant to an underwriting agreement (the “Underwriting Agreement”) entered into between the Company and Aegis Capital Corp. (the “Underwriter”), which was restated prior to the closing of the offering to reflect certain applicable restrictions under FINRA’s Corporate Financing Rule 5110 and other non-material amendments. The restated Underwriting Agreement is filed as an exhibit to this report, and the description of the terms of the restated Underwriting Agreement in this report is qualified in its entirety by reference to such exhibit.

The common stock was offered and sold pursuant to the Company’s effective shelf registration statement on Form S-3 and an accompanying prospectus (Registration Statement No. 333-200410) filed with the Securities and Exchange Commission (the “SEC”) on November 20, 2014, and declared effective by the SEC on December 2, 2014, a preliminary prospectus supplement filed with the SEC on November 28, 2017, and a final prospectus supplement filed with the SEC on November 30, 2017, in connection with the Company’s shelf takedown relating to the offering.

The Company paid the Underwriter a discount of 7% to the public offering price with respect to shares purchased in the offering by investors who did not have a pre-existing relationship with the Company prior to the offering (the “New Investors”), and a discount of 3.5% to the public offering price with respect to shares purchased in the offering by investors who did have a pre-existing relationship with the Company. In addition to the underwriting discounts, the Company issued to the Underwriter 110,000 shares of its common stock, equal to 2% of the aggregate shares of common stock sold in the offering to the New Investors.

The net proceeds to the Company from the sale of the shares of common stock were approximately $4.2 million, after deducting underwriting discounts and commissions and other offering expenses payable by the Company, assuming no exercise by the Underwriter of the 45-day option which the Company has granted the Underwriter under the terms of the Underwriting Agreement to purchase up to an additional 3,375,000 shares of common stock to cover over-allotments, if any.

*Filed herewith.
