On November 6, 2013, LGI Homes, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Deutsche Bank Securities Inc., JMP Securities LLC and J.P. Morgan Securities LLC, as representatives of the underwriters listed on Schedule I thereto (the “Underwriters”), providing for the offer and sale of an aggregate of 9,000,000 shares of the Company’s common stock issued and sold by the Company at a price of $11.00 per share ($10.23 per share, net of underwriting discount). Pursuant to the Underwriting Agreement, the Company also provided the Underwriters with an option for a period of 30 days to purchase up to an additional 1,350,000 shares of common stock to cover over-allotments. This option was exercised in full on November 8, 2013 and will close concurrently with the closing of the firm shares purchased in connection with the initial public offering on November 13, 2013.
