Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements have been prepared from the books and records of the Company and include all normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and Rule 8-03 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission (the “SEC”). Accordingly, these interim financial statements do not include all of the information and footnotes required for complete annual financial statements. Interim results are not necessarily indicative of the results that may be expected for the full year. Interim unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and the notes thereto included in the Company’s Annual

Report on Form 10-K for the year ended June 30, 2022, filed with the SEC on October 11, 2022 (the “Annual Report”), from which the accompanying condensed consolidated balance sheet dated June 30, 2022 was derived.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated as part of the consolidation. Non-controlling interest in the consolidated financial statements represented the share of the loss in iBio CDMO, LLC (“iBio CDMO”) for an affiliate of Eastern Capital Limited (“Eastern Capital”) through November 1, 2021, the date the Company acquired the remaining interest in iBio CDMO. See Note 6 – Significant Transactions.

Going Concern

The history of significant losses, the negative cash flow from operations, the limited cash resources on hand and the dependence by the Company on its ability to obtain additional financing to fund its operations after the current cash resources are exhausted raises substantial doubt about the Company's ability to continue as a going concern. In an effort to remain a going concern and increase cash reserves, the Company completed a public equity offering, reduced its work force by approximately 60% (a reduction of approximately 69 positions) in November 2022, and ceased operations of its CDMO thereby reducing annual spend on expenses by approximately 50%. Additionally, the Company continues its efforts to sell its CDMO assets and facilities that were initiated by management in July 2022. (See Note 3 – Discontinued Operations for more information.) Additional potential options being considered to further increase liquidity include lowering the Company’s expenses further, focusing product development on a select number of product candidates, the sale or out-licensing of certain product candidates, equipment sales, raising money from capital markets, grant revenue or collaborations, or a combination thereof.

The Company’s cash, cash equivalents, restricted cash and investments in debt securities of $9.9 million as of December 31, 2022, is not anticipated to be sufficient to support operations through the third quarter of Fiscal 2023 unless the Company reduces its burn rate further, sells the CDMO assets for amounts above its term note payable, or increases its capital as described above. Regardless of whether the Company is able to reduce its burn rate or sell or out-license certain assets or parts of the business, the Company will need to raise additional capital in order to fully execute its longer-term business plan. It is the Company’s goal to implement one or more potential options described above to allow the Company to have a cash runway for at least 12 months from the date of the filing of this Quarterly Report on Form 10-Q. However, there can be no assurance that the Company will be successful in implementing any of the options that it is evaluating.

The accompanying financial statements do not include any adjustments related to the recoverability and classification of assets or the amounts and classification of liabilities that may result from the possible inability of the Company to continue as a going concern.

Reverse Stock Split

On September 22, 2022, the Company's Board of Directors approved the implementation of a reverse stock split (the “Reverse Split”) at a ratio of one-for-twenty five (1:25) shares of the Company's common stock, par value $0.001 (the “Common Stock”). The Reverse Split was effective as of October 7, 2022. All share and per share amounts of the Common Stock presented have been retroactively adjusted to reflect the Reverse Split.
