(“Antigen”), has undertaken work on immunomedicines incorporating proprietary vaccine formulations. On January 18, 2017, the Company closed an Acquisition Agreement pursuant to which the Company acquired a 51% interest in Hema Diagnostic Systems, LLC, (“HDS”) a Florida limited liability company established in December, 2000 to market and distribute rapid test devices including infectious diseases. (See Note 10) Since 2002, HDS has been developing an expanding line of rapid diagnostic tests (RDTs) including such diseases as Human Immunodeficiency Virus (HIV) – 1/2, tuberculosis, malaria, hepatitis, syphilis, typhoid and dengue as well as other infectious diseases.

The Company will continue to require substantial funds to implement its new investment acquisition plans. Management’s plans in order to meet its operating cash flow requirements include financing activities such as private placements of its common stock, preferred stock offerings, and issuances of debt and convertible debt instruments. Management is also actively pursuing financial and strategic alternatives, including strategic investments and divestitures, industry collaboration activities and strategic partners. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern. There are no assurances that such additional funding will be achieved and that the Company will succeed in its future operations. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company’s inability to obtain required funding in the near future or its inability to obtain funding on favorable terms will have a material adverse effect on its operations and strategic development plan for future growth. If the Company cannot successfully raise additional capital and implement its strategic development plan, its liquidity, financial condition and business prospects will be materially and adversely affected, and the Company may have to cease operations. Business combinations Business combinations are accounted for using the acquisition method of accounting. Acquisition cost is measured as the aggregate of the fair value at the date of acquisition of the assets given, equity instruments issued or liabilities incurred or assumed. Acquisition related costs are expensed as incurred (except for those costs arising on the issue of equity instruments which are recognized directly in equity). Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured at fair value on the acquisition date. Goodwill is measured as the excess of the acquisition cost and the amount of any non-controlling interest, over the fair value of the identifiable net assets acquired.

Note 1 - Basis of Presentation:

Generex Biotechnology Corporation (“Generex” or the “Company”), was formed in the State of Delaware on September 4, 1997 and its year-end is July 31. It is engaged primarily in the research and development of drug delivery systems and the use of the Company’s proprietary technology for the administration of formulations of large molecule drugs to the oral (buccal) cavity using a hand-held aerosol applicator; and through the Company’s wholly-owned subsidiary, Antigen Express, Inc. (“Antigen”), has undertaken work on immunomedicines incorporating proprietary vaccine formulations.

On January 18, 2017, the Company closed an Acquisition Agreement pursuant to which the Company acquired a 51% interest in Hema Diagnostic Systems, LLC, (“HDS”) a Florida limited liability company established in December, 2000 to market and distribute rapid test devices including infectious diseases. (See Note 10) Since 2002, HDS has been developing an expanding line of rapid diagnostic tests (RDTs) including such diseases as Human Immunodeficiency Virus (HIV) – 1/2, tuberculosis, malaria, hepatitis, syphilis, typhoid and dengue as well as other infectious diseases.

The accompanying unaudited interim consolidated financial statements (“interim statements”) have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain information and disclosures required by generally accepted accounting principles for complete financial statements are not included herein. The interim statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s latest Annual Report on Form 10-K. The results for the six month period ended January 31, 2017 may not be indicative of the results for the entire year.

Interim statements are subject to possible adjustments in connection with the annual audit of the Company’s accounts for fiscal year 2017. In the Company’s opinion, all adjustments necessary for a fair presentation of these interim statements have been included and are of a normal and recurring nature.

On March 14, 2017, the Company effected a one-for-one thousand (1:1,000) reverse stock split whereby the Company (i) decreased the number of authorized shares of Common Stock by a ratio equal to one-for-one thousand (1:1,000) (the “Reverse Split Ratio”), and (ii) correspondingly and proportionately decreased, by a ratio equal to the Reverse Split Ratio, the number of issued and outstanding shares of Common Stock (the “Reverse Stock Split”). Proportional adjustments for the reverse stock split were made to the Company's outstanding stock options, warrants and equity incentive plans for all periods presented.

Going Concern

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has experienced negative cash flows from operations since inception and has an accumulated deficit of approximately $391 million and a working capital deficiency of approximately $23.6 million at January 31, 2017. The Company has funded its activities to date almost exclusively from debt and equity financings, as well as the sale of non-essential real estate assets in fiscal 2012 through the first quarter of fiscal 2014.

The Company will continue to require substantial funds to implement its new investment acquisition plans. Management’s plans in order to meet its operating cash flow requirements include financing activities such as private placements of its common stock, preferred stock offerings, and issuances of debt and convertible debt instruments. Management is also actively pursuing financial and strategic alternatives, including strategic investments and divestitures, industry collaboration activities and strategic partners.

These factors raise substantial doubt regarding the Company’s ability to continue as a going concern. There are no assurances that such additional funding will be achieved and that the Company will succeed in its future operations. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company’s inability to obtain required funding in the near future or its inability to obtain funding on favorable terms will have a material adverse effect on its operations and strategic development plan for future growth. If the Company cannot successfully raise additional capital and implement its strategic development plan, its liquidity, financial condition and business prospects will be materially and adversely affected, and the Company may have to cease operations.

Business combinations

Business combinations are accounted for using the acquisition method of accounting. Acquisition cost is measured as the aggregate of the fair value at the date of acquisition of the assets given, equity instruments issued or liabilities incurred or assumed. Acquisition related costs are expensed as incurred (except for those costs arising on the issue of equity instruments which are recognized directly in equity). Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured at fair value on the acquisition date. Goodwill is measured as the excess of the acquisition cost and the amount of any non-controlling interest, over the fair value of the identifiable net assets acquired.
