On December 12, 2017, GigCapital, Inc., a Delaware corporation (the “Company”), consummated its initial public offering (the “IPO”) of 12,500,000 units (the “Public Units”), as previously disclosed in its Current Report on Form 8-K (the “IPO Closing 8-K”) filed with the Securities and Exchange Commission (the “SEC”) on December 12, 2017. Each Public Unit consists of one share of common stock, $0.0001 par value (“Common Stock”), three-quarters ( ³⁄₄) of one warrant to purchase one share of Common Stock (“Public Warrant”), and one right to receive one-tenth ( ¹⁄₁₀) of one share of Common Stock upon the Company’s completion of an initial business combination. Each whole Public Warrant is exercisable for one share of Common Stock at a price of $11.50 per full share. The Public Units were sold at an offering price of $10.00 per unit, and the IPO generated aggregate gross proceeds of $125,000,000.

As also previously disclosed in the IPO Closing 8-K, simultaneously with the closing of the IPO and the sale of the Public Units, the Company consummated the private placement (“Private Placement”) of an aggregate of 489,500 units (the “Private Placement Units”), at a price of $10.00 per Private Placement Unit, pursuant to unit purchase agreements between the Company, and each of GigAcquisitions, LLC, a Delaware limited liability company (“Sponsor”), Cowen Investments LLC, a Delaware limited liability company (“Cowen Investments”), Irwin Silverberg (“Silverberg”), Jeffrey Bernstein (“Bernstein” and, together with Sponsor, Cowen Investments, Silverberg and Bernstein, the “Founders”). Among the Founders, Sponsor purchased 356,000 Private Placement Units; Cowen Investments purchased 89,000 Private Placement Units; Silverberg purchased 40,050 Private Placement Units; and Bernstein purchased 4,450 Private Placement Units. The Private Placement generated aggregate gross proceeds of $4,895,000. The Private Placement Units are substantially similar to the Public Units, except for certain differences in the warrants included in the Private Placement Units (the “Private Placement Warrants”). Unlike the Public Warrants, if held by the original holder or its permitted transferees, the Private Placement Warrants (i) may be exercised for cash or on a cashless basis at such time as they become exercisable, (ii) are not redeemable by the Company, and (iii) subject to certain limited exceptions, will be subject to transfer restrictions until one year following the consummation of the Company’s initial business combination. If the Private Placement Warrants are held by holders other than its initial holders or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by holders on the same basis as the Public Warrants, except as set forth in the Company’s initial registration statement on Form S-1, as amended (File No. 333-221581) and declared effective by the SEC on December 7, 2017 (the “Initial Registration Statement”). The material terms of the unit purchase agreements are set forth in the Initial Registration Statement and incorporated by reference herein.

A total of $125,000,000, comprised of $122,500,000 of the proceeds from the IPO and $2,500,000 of the proceeds of the sale of the Private Placement Units, were placed in a U.S.-based trust account at JPMorgan Chase Bank, N.A., maintained by Continental Stock Transfer & Trust Company, acting as trustee.

An audited balance sheet as of December 12, 2017 reflecting receipt of the proceeds upon consummation of the IPO and the Private Placement has been issued by the Company and is included as Exhibit 99.1 to this Current Report on Form 8-K.
