On November 10, 2015, Neos Therapeutics, Inc. (the “Company”) announced its financial results for the quarter ended September 30, 2015. The full text of the press release issued in connection with the announcement is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The information in this Form 8-K (including Exhibit 99.1) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.

Item 8.01. Other Events.

On January 9, 2015, the Company submitted to the U.S. Food and Drug Administration (the “FDA”) a New Drug Application (the “NDA”) under section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act for Cotempla XR-ODT™ (Methylphenidate Extended Release Orally Disintegrating), 10 mg, 20 mg, and 30 mg tablets.  As previously disclosed, on October 16, 2015, the Company received a notification from the FDA stating that, as part of its ongoing review of the Company’s NDA, the FDA had identified deficiencies that precluded discussion of labeling and postmarketing requirements/commitments at that time.

On November 10, 2015, the Company issued a press release announcing that it received a complete response letter from the FDA for the Company’s NDA. A copy of the press release is filed herewith as Exhibit 99.1 and is incorporated into this Item 8.01 by reference.
