Item 1.01.                                        Entry into a Material Definitive Agreement.

On September 20, 2017, Dejana Truck & Utility Equipment Company, LLC (formerly known as Acquisition Delta LLC) (“Delta”) entered into a Second Amendment (the “Amendment”) to the Asset Purchase Agreement dated June 15, 2016 and amended on February 27, 2017 (the “Agreement”), with Peter Paul Dejana Family Trust 12/31/98 (the “Trust”), Peteco Kings Park Inc. (formerly known as Dejana Truck & Utility Equipment Company, Inc.) (“DTUENY”) and, solely in the capacity of appointed agent, Andrew Dejana.  Pursuant to the Agreement, Delta, a wholly-owned subsidiary of Douglas Dynamics, Inc. (the “Company”), acquired substantially all of the assets of DTUENY and specified entities directly or indirectly owned by the Trust on July 15, 2016.

As previously disclosed in the Company’s Current Reports on Form 8-K filed on June 20, 2016 and March 1, 2017, the Agreement, as amended, provided for potential earnout payments of up to $26.0 million in the aggregate, contingent on the financial performance of the acquired business for each of the fiscal years ending December 31, 2016, 2017 and 2018.  In light of the financial performance of the acquired business that occurred for the fiscal year ended December 31, 2016, as well as the Company’s expectation for the performance of the business for the years ended December 31, 2017, and December 31, 2018, the Company anticipates that a portion of the $16.0 million of the potential remaining earnout payouts could be unearned.  The Amendment extends the earnout measurement periods for an additional two years, namely the fiscal years ended December 31, 2019 and December 31, 2020, with the potential for the selling entities to earn up to 50% of the remaining earnout payments unearned based on the original earnout targets and measurement periods.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.
