Highlights:

· Generated fourth quarter earnings per diluted share of $0.66, compared to $0.58 for the comparable quarter in the prior year

March 7, 2016 — Milwaukee, Wisconsin — Douglas Dynamics, Inc. (NYSE: PLOW), North America’s premier manufacturer of vehicle attachments and equipment today announced financial results for the fourth quarter and full year ended December 31, 2015.

Fourth Quarter Results

For the fourth quarter of 2015, net sales were $118.8 million, representing an 18.7% increase over the fourth quarter of 2014 net sales of $100.1 million. The increase reflects the addition of Henderson Products and strong in-season shipments of equipment and service parts in the core business.

James L. Janik, Chairman, President and Chief Executive Officer of the Company commented, “We are very pleased with our results for the fourth quarter, especially as winter got off to a very slow start in our core markets. The fact we were still able to produce a very strong fourth quarter indicates that near-term pent up demand continued to unwind. While winter storm Jonas was a significant weather event, snowfall is still substantially below average across North America this winter.”

Janik added, “At the start of 2015, we did not expect to produce another record year following a fantastic performance in 2014. However, we were able to do just that because of the relentless determination of our team, the ongoing execution of DDMS, the acceptance of new products introduced in 2015, and the continued release of pent up demand in the market. Incredibly, both

our core business and Henderson built upon their record 2014 performance and separately produced record results again in 2015.”

“Since acquiring Henderson at the end of 2014, we have been very impressed with the financial performance of the business, the entire team at Henderson. More importantly, the level of collaboration between teams and acceptance of DDMS has exceeded our expectations. With the initial integration complete, we look forward to building upon our success and meeting the considerable demand for Henderson’s market leading products and services in the years to come,” Janik concluded.

Net income was $15.1 million, or $0.66 per diluted share based on weighted average shares of 22.4 million, in the fourth quarter of 2015 compared to net income of $13.0 million, or $0.58 per diluted share based on weighted average shares of 22.2 million, in the fourth quarter of 2014.

Full Year Results

For the full year 2015, net sales were a record $400.4 million, compared to $303.5 million in 2014. This increase was primarily driven by the addition of Henderson Products plus increased sales of both equipment units and parts and accessories in the core business. Sales of parts and accessories increased to $51.0 million for the full year 2015 compared to $49.3 million in 2014.

For the full year, gross profit increased from $116.3 million in 2014 to $132.9 million in 2015. This increase was driven primarily by the addition of Henderson Products and slightly higher unit volume in the core business.

Net income was $44.2 million, or $1.94 per diluted share based on weighted average shares of 22.3 million shares, for the full year 2015. This compares to net income of $40.0 million, or $1.77 per diluted share based on weighted average shares of 22.2 million shares, for the full year 2014. Again, the increase was driven primarily by the addition of Henderson Products and slightly higher unit volume in the core business. The full-year 2015 and 2014 results included certain non-cash purchase accounting adjustments attributable to the acquisition of Henderson Products in December 2014 and TrynEx International in May 2013.

The Company reported Adjusted EBITDA of $96.5 million for the full year 2015, compared to Adjusted EBITDA of $87.9 million for the full year 2014.

The effective tax rate for the full year 2015 was 33.3%, which is lower than previously expected due to the release of valuation allowances in several states.

Balance Sheet and Liquidity

For the full year 2015, the Company reported net cash provided by operating activities of $56.5 million compared to net cash provided by operating activities of $53.7 million in 2014. As Henderson Products was acquired on December 31, 2014, Douglas Dynamics assumed all of its assets and liabilities on that date, which is reflected in the attached Consolidated Balance Sheet.

Inventory was $51.6 million at the end of the fourth quarter of 2015, compared to $48.2 million at the end of 2014. The increase partially relates to the opening of a new Henderson upfit facility in Missouri in July 2015.

Accounts receivable at the end of 2015 were $67.7 million. This compares to $60.9 million at the end of the fourth quarter of 2014. The change was primarily driven by higher sales volume compared to the previous year.

The Company maintained cash on hand at December 31, 2015 of $36.8 million, compared to $24.2 million at the end of 2014. The increase in cash on hand returns the Company towards its more historical cash balance following the acquisition of Henderson Products at the end of 2014 and provides increased liquidity for funding the quarterly dividend and potential acquisitions.

Dividend Policy

As previously reported, on December 10, 2015 the Company declared a quarterly cash dividend of $0.2225 per share on its common stock. The dividend was paid on December 31, 2015, to stockholders of record as of the close of business on December 21, 2015.

The Company also has announced that its board of directors approved and declared a quarterly cash dividend increase of 5.6%, to $0.235 per share of the Company’s common stock. The declared dividend will be paid on March 31, 2016 to stockholders of record as of the close of business on March 21, 2016.

Mr. Janik noted, “Based on our tremendous results in 2015, the general outlook for the industry, plus our continued financial strength, the Board and management agreed it is appropriate to increase the dividend in 2016 by a larger amount than in previous years. We are proud that our performance and financial management has allowed us to increase the dividend eight times in less than six years as a public company. The increase was decided upon by analyzing our ability to fund the dividend for the foreseeable future, which the Board then weighed against other redistribution options and future potential investment opportunities. Our primary capital allocation goal remains the same; to return excess capital to shareholders via a robust dividend which can be sustained in all market environments.”

Outlook

Based on 2015 results, the overall economic climate, dealer sentiment, current snowfall and industry trends, the Company is providing the following financial outlook:

· Net sales for the full year 2016 are expected to range between $310 million and $370 million.

· Adjusted EBITDA is predicted to range from $55 million to $85 million.

· Earnings per share are expected to range from $1.05 per share to $1.65 per share.

· Included in the 2016 outlook is a benefit of approximately $10 million, which equates to approximately $0.27 per share, resulting from the recent favorable settlement of a lawsuit. The payment, which was received during the first quarter 2016, will be disclosed

Adjusted EBITDA represents net income before interest, taxes, depreciation and amortization, as further adjusted for stock based compensation, loss on extinguishment of debt, non-cash purchase accounting adjustments and certain charges related to certain unrelated legal fees and consulting fees. The Company uses, and believes its investors benefit from the presentation of, Adjusted EBITDA in evaluating the Company’s operating performance because Adjusted EBITDA provides the Company and its investors with additional tools to compare its operating performance on a consistent basis by removing the impact of certain items that management believes do not directly reflect the Company’s core operations. In addition, the Company believes that Adjusted EBITDA is useful to investors and other external users of its consolidated financial statements in evaluating the Company’s operating performance as compared to that of other companies, because it allows them to measure a company’s operating performance without regard to items such as interest expense, taxes, depreciation and amortization, which can vary substantially from company to company depending upon accounting methods and book value of assets and liabilities, capital structure and the method by which assets were acquired. The Company’s management also uses Adjusted EBITDA for planning purposes, including the preparation of its annual operating budget and financial projections, and to evaluate the Company’s ability to make certain payments, including dividends, in compliance with its senior credit facilities, which is determined based on a calculation of “Consolidated Adjusted EBITDA” that is substantially similar to adjusted EBITDA.

Consistent with Regulation G under the U.S. federal securities laws, the non-GAAP measure in this press release has been reconciled to the nearest GAAP measure, and this reconciliation is located under the heading “Net Income to Adjusted EBITDA Reconciliation” following the Consolidated Statements of Cash Flows included in this press release.
