Underwriting Agreement

On November 6, 2018, Neos Therapeutics, Inc., a Delaware corporation (the “Company”), entered into an underwriting agreement (the “Underwriting Agreement”) with Cantor Fitzgerald & Co., as representative of the several underwriters listed therein (the “Underwriters”), related to an underwritten public offering (the “Offering”) of 17,391,304 shares (the “Shares”) of the Company’s common stock, $0.001 par value per share (the “Common Stock”), at a public offering price of $2.30 per Share (the “Offering Price”), before underwriting discounts and commissions.  Pursuant to the terms of the Underwriting Agreement, the Company granted the Underwriters an option, exercisable for 30 days, to purchase up to an additional 2,608,695 shares of Common Stock. The gross proceeds to the Company, before deducting the underwriting discounts and estimated expenses associated with the Offering payable by the Company, are expected to be approximately $40 million (assuming the Underwriters do not exercise their option to purchase additional shares).  The closing of the Offering is expected to occur on or about November 8, 2018, subject to the satisfaction of customary closing conditions.

The Shares are being offered and sold pursuant to a prospectus dated August 12, 2016 and a prospectus supplement dated November 6, 2018, in connection with a takedown from the Company’s shelf registration statement on Form S-3 (Registration No. 333-212809) (the “Registration Statement”), which the U.S. Securities and Exchange Commission declared effective on August 12, 2016.

The Underwriting Agreement contains customary representations, warranties, covenants, conditions to closing, indemnification and other obligations of the parties and termination provisions.

A copy of the legal opinion of Goodwin Procter LLP, relating to the validity of the Shares issued in the Offering, is filed as Exhibit 5.1 to this Current Report on Form 8-K and is filed with reference to, and is hereby incorporated by reference into, the Registration Statement.

The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the text of the Underwriting Agreement, which is included as Exhibit 1.1 to this Current Report on Form 8-K and incorporated by reference herein.

The Underwriting Agreement has been filed with this Current Report on Form 8-K to provide investors and security holders with information regarding its terms.  It is not intended to provide any other factual information about the Company.  The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, and were solely for the benefit of the parties to such agreement.
