Exhibit 99.1

iBio Announces Partial Adjournment of Annual Meeting to December 22

- Shareholders Presently Supporting Reverse Split and Authorized Share Proposals by a 2-to-1 Margin -

Bryan, Texas / December 10, 2021 / (GLOBE NEWSWIRE) / iBio, Inc. (NYSEA:IBIO) (“iBio” or the “Company”), a developer of next-generation biopharmaceuticals and pioneer of the sustainable, plant-based FastPharming Manufacturing System®today announced that its annual meeting of stockholders (the "Annual Meeting") scheduled for and convened yesterday has been partially adjourned to December 22, 2021 at 9:00 a.m. Eastern Time.

A quorum was present at yesterday’s Annual Meeting, and Proposals 1 (election of directors), 2 (appointment of auditors) and 3 (Say-on-Pay) put forth in the definitive proxy statement received the requisite votes for approval. The Company’s stockholders also approved Proposal 6 (adjournment of the Annual Meeting) for the purpose of continuing to solicit votes in favor of Proposal 4 (reverse stock split) and Proposal 5 (authorized share decrease).

With over 60% of all shares voted, iBio stockholders are in favor of the reverse split and authorized share decrease by approximately a 2-to-1 margin. Results of votes cast “FOR” Proposals 4 and 5 to-date are 64% and 67%, respectively. Additionally, both of the leading proxy advisory firms (Glass Lewis and ISS) have recommended that stockholders vote “FOR” the proposals. With a clear plurality of the vote in favor of the proposals and strong, independent third-party support for the reverse split and authorized share decrease, the Company is allowing additional time for stockholders holding approximately 40% of the shares that have yet to be voted the opportunity to express their views. Proposals 4 and 5 require a majority of all shares outstanding to vote “FOR” the measures, not just a plurality of the vote.

“Our goal is to enable as many stockholders as possible to exercise their right to vote,” said Tom Isett, iBio’s Chairman and CEO, “The hurdle is high; securing affirmative votes from a majority of the outstanding shares entitled to vote. However, so are the stakes; the ability to complete our transformation and grow the Company. Given that a sizeable majority of shareholders who have already voted support these two proposals, we intend to continue our efforts to pass these measures so that we can execute iBio’s growth strategy and bring the benefits of FastPharming to customers and patients, while returning value to our loyal stockholders. Therefore, in order to save the company further solicitation costs and provide greater certainty, it is important that all shareholders vote as soon as possible. You can easily vote your shares by contacting Okapi Partners at 1-844-203-3605.”

If you have already voted your shares “FOR” Proposals 4 and 5, you do not need to vote again, and we thank you for your support. If you did not vote at all, abstained from voting for, or voted against with respect to the proposals, we kindly ask you to vote, or to reconsider your vote.

For additional information on the Proposals, please see our Shareholder Vote FAQ.
