Forward-Looking Statements This presentation may contain "forward-looking statements" as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements contained herein speak only as of the date they are made and give our current expectations or forecasts of future events. These forward looking statements can be identified by the use of forward-looking words, such as "may," "could," "should," "estimate," "project," "forecast," "intend," "expect," "anticipate," "believe," "target," "plan" or other comparable words, or by discussions of strategy that may involve risks and uncertainties. These forward-looking statements are subject to numerous assumptions, risks and uncertainties which could materially affect our business, financial condition or future results including, but not limited to, risks and uncertainties with respect to: the Company's leverage; liabilities imposed by the Company's debt instruments; market demand; competitive factors; supply constraints; material and energy costs; technology factors; litigation; government and regulatory actions; the Company's accounting policies; future trends; general economic and currency conditions; various conditions specific to the Company's business and industry; the spin-off from TriMas Corporation; risks inherent in the achievement of cost synergies and the timing thereof in connection with the Westfalia acquisition, including whether the acquisition will be accretive; the Company's ability to promptly and effectively integrate Westfalia; the performance and costs of integration of Westfalia; the Company's ability to successfully complete the acquisition of the Brink Group; the timing and amount of repurchases of the Company s common stock, if any; and other risks that are discussed in the Company's most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q or Current Reports on Form 8-K. The risks described herein are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deemed to be immaterial also may materially adversely affect our business, financial position and results of operations or cash flows. We caution readers not to place undue reliance on such statements, which speak only as of the date hereof. We do not undertake any obligation to review or confirm analysts' expectations or estimates or to release publicly any revisions to any forward-looking statement to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events. 2

Non-GAAP Financial Measures In this presentation, certain non-gaap financial measures may be used. Except as otherwise disclosed herein, reconciliations of non-gaap financial measures to the most directly comparable GAAP financial measure may be found at the end of this presentation. Additional information is available at www.horizonglobal.com. (1) Refer to Appendix, "Company and Business Segment Financial Information" which details certain costs, expenses, other charges, and gains or income, collectively described as ''Special Items", that are included in the determination of operating profit (loss) under GAAP, but that management would not consider important in evaluating the quality of the Company's operating results as they are not indicative of the Company's core operating results or may obscure trends useful in evaluating the Company's continuing activities. Accordingly, the Company presents adjusted operating profit (loss) and adjusted corporate expenses excluding these Special Items to help investors evaluate our operating performance and trends in our business consistent with how management evaluates such performance and trends. Further, the Company presents adjusted operating profit (loss) excluding these Special Items, to provide investors with a better understanding of the Company's view of the fourth quarter and full year results as compared to the Company's 2017 guidance and prior periods. (2) We evaluate growth in our operations on both an as reported basis and a constant currency basis. The constant currency presentation, which is a non-gaap measure, excludes the impact of fluctuations in foreign currency exchange rates. We believe providing constant currency information provides valuable supplemental information regarding our growth, consistent with how we evaluate our performance. Constant currency revenue results are calculated by translating current period revenue in local currency using the prior period s currency conversion rate. This non-gaap measure has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of our results as reported under GAAP. Our use of this term may vary from the use of similarly-titled measures by other issuers due to the potential inconsistencies in the method of calculation and differences due to items subject to interpretation. See Appendix, "Constant Currency Reconciliation". (3) Refer to Appendix, "Additional Information Regarding Special Items Impacting Reported GAAP Financial Measures", which details certain costs, expenses, other charges, and gains or income, collectively described as ''Special Items'' that are included in the determination of net income (loss) and earnings (loss) per share under GAAP, but that management would not consider important in evaluating the quality of the Company's operating results as they are not indicative of the Company's core operating results or may obscure trends useful in evaluating the Company's continuing activities. Accordingly, the Company presents adjusted net income (loss) and adjusted diluted earnings (loss) per share excluding these Special Items to help investors evaluate our operating performance and trends in our business consistent with how management evaluates such performance and trends. (4) Refer to Appendix, "LTM Bank EBITDA as Defined in Credit Agreement", which reconciles net income (loss) to "Consolidated Bank EBITDA" as defined in our Credit Agreement dated June 30, 2015, as amended, for all periods presented. We believe this reconciliation provides valuable supplemental information regarding our capital structure, consistent with how we evaluate our performance. Net leverage ratio is calculated by dividing "Total Consolidated Indebtedness" by "Consolidated Bank EBITDA". For the twelve month periods ended December 31, 2017, September 30, 2017, June 30, 2017, and March 31, 2017, "Total Consolidated Indebtedness" refers to the sum of "long-term debt" and "current maturities, long-term debt", with our Convertible Notes at their face value of $125 million and excluding certain credit facilities as defined in our Credit Agreement, less unrestricted domestic cash and 65% of unrestricted foreign cash. For the twelve month period ended December 31, 2016, "Total Consolidated Indebtedness" refers to the sum of "long-term debt" and "current maturities, long-term debt", excluding certain credit facilities as defined in our Credit Agreement, less unrestricted domestic cash and 65% of unrestricted foreign cash. Domestic and foreign unrestricted cash included in the calculation were $5.9 million and $15.4 million, respectively, as of December 31, 2017, $6.3 million and $9.2 million, respectively, as of September 30, 2017, $10.6 million and $18.8 million, respectively, as of June 30, 2017, $5.2 million and $16.3 million, respectively, as of March 31, 2017, and $30.0 million and $13.1 million, respectively, as of December 31, 2016. (5) "Working Capital" defined as "total current assets" excluding "cash and cash equivalents" and "deferred income taxes", less "total current liabilities" excluding "current maturities, long-term debt". 3

(5.1)% 4.7% 30.3% 3.3% (1.0)% 208.6% 21.6% 36.2% We evaluate growth in our operations on both an as reported and a constant currency basis. The constant currency presentation, which is a non-gaap measure, excludes the impact of fluctuations in foreign currency exchange rates. We believe providing constant currency information provides valuable supplemental information regarding our growth, consistent with how we evaluate our performance. Constant currency revenue results are calculated by translating current year revenue in local currency using the prior year's currency conversion rate. This non-gaap measure has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of our results as reported under GAAP. Our use of this term may vary from the use of similarly-titled measures by other issuers due to the potential inconsistencies in the method of calculation and differences due to items subject to interpretation. 28
