On September 25, 2015, Sysorex Global Holdings Corp. (“we” or “Sysorex”) entered into an underwriting agreement (the “Underwriting Agreement”) with B. Riley & Co., LLC, as representative of the several underwriters named therein (the “Underwriters”), relating to the issuance and sale of 5,250,000 shares of our common stock, par value $0.001 per share. The price to the public in this offering is $1.00 per share. Under the terms of the Underwriting Agreement, we also granted the Underwriters an option exercisable for 30 days from the closing date to purchase up to an additional 787,500 shares at the public offering price.

After deducting underwriting discounts and commissions and estimated offering expenses, we expect the net proceeds from the offering to be approximately $4.9 million, or approximately $5.6 million if the Underwriters exercise in full the over-allotment option to purchase additional shares. We intend to use the net proceeds from the offering for general corporate purposes, which may include business development activities, capital expenditures, working capital and general and administrative expenses.

The offering is scheduled to close on or about September 30, 2015, subject to customary closing conditions.

The Underwriting Agreement contains customary representations, warranties and agreements by us, customary conditions to closing, indemnification obligations of us and the Underwriters, 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.

The offering is being made pursuant to our registration statement on Form S-3 (Registration Statement No. 333-204159) previously filed with the Securities and Exchange Commission and declared effective May 28, 2015 and a related prospectus supplement filed with the Securities and Exchange Commission.
