On November 29, 2017, iBio, Inc., a Delaware corporation (the “Company”), entered into an underwriting agreement (the “Underwriting Agreement”) with Aegis Capital Corp. (the “Underwriter”), relating to the issuance and sale of 22,500,000 shares of the Company’s common stock, par value $0.001 per share (“Common Stock”). The public offering price for each share of Common Stock is $0.20.

The Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriter, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Underwriting Agreement.

Pursuant to the Underwriting Agreement, subject to certain exceptions, (i) the Company agreed not to sell or otherwise dispose of any shares of Common Stock for a period ending 90 days after the date of the Underwriting Agreement and (ii) the Company’s officers, directors and certain key shareholders agreed not to sell or otherwise dispose of any of the Company’s Common Stock held by them for a period ending 90 days after the date of the Underwriting Agreement, in each case, without first obtaining the written consent of the Underwriter, subject to certain exceptions.

The Common Stock is being 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, and a preliminary and final prospectus supplement filed with the SEC in connection with the Company’s takedown relating to the offering. A copy of the opinion of Andrew Abramowitz, PLLC relating to the legality of the issuance and sale of the shares of Common Stock in the offering is attached as Exhibit 5.1 hereto.

The Company will pay the Underwriter a discount of 7% to the public offering price with respect to any shares purchased in this offering by investors, other than certain investors who have a pre-existing relationship with the Company, and a discount of 3.5% to the public offering price with respect to any shares purchased in this offering by certain investors who have a pre-existing relationship with the Company. In addition to the underwriting discounts, the Company has agreed to issue the Underwriter shares of its common stock equal to 2% of the aggregate shares of common stock sold in this offering, other than shares of common stock sold to certain investors who have a pre-existing relationship with the Company.

The net proceeds to the Company from the sale of the shares of Common Stock is expected to be approximately $4,180,000 million, after deducting underwriting discounts and commissions and other estimated 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.

The Underwriting Agreement is filed as an exhibit to this report, and the description of the terms of the Underwriting Agreement in this report is qualified in its entirety by reference to such exhibit. The offering is expected to close on or about November 30, 2017, subject to customary closing conditions.

The foregoing description of the terms of the Underwriting Agreement does not purport to be complete and is subject to, and qualified in its entirety by reference to, the Underwriting Agreement, which is filed herewith as Exhibit 1.1 and is incorporated herein by reference.

*Filed herewith.
