Investor Presentation Summer 2017 Exhibit 99.1

Huttig Building Products Summer 2017 Company Overview SAFE HARBOR / FORWARD LOOKING STATEMENT These presentation materials may contain forward-looking statements as defined by the U.S. Private Securities Litigation Reform Act of 1995 (“Reform Act”). Statements made in this presentation looking forward in time, including, but not limited to, statements regarding our current views with respect to future financial performance, the housing market, distribution channels, sales, supplier relationships, inventory levels, the ability to meet customer needs, competitive posture, obligations with respect to environmental remediation (including remediation of the Montana site in accordance with regulatory requirements and cost estimates), deterioration in our relationship with our unionized employees, including work stoppages or other disputes, and the financial impact of litigation or otherwise, are included pursuant to the “safe harbor” provision of the Reform Act. These statements present management’s expectations, beliefs, plans and objectives regarding our future financial performance and assumptions or judgments concerning such performance. These forward-looking statements are based on current projections, estimates, assumptions and judgments, and involve known and unknown risks and uncertainties. We disclaim any obligation to publicly update or revise any of these forward-looking statements, whether as a result of new information, future events or otherwise. There are a number of other important factors that could cause our actual results or outcomes to differ materially from those expressed or implied in the forward-looking statements, including, but not limited to, those detailed in Huttig’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the U.S. Securities and Exchange Commission (“SEC”) and other filings with the SEC, all of which are available on our website. Forward-looking statements should not be relied upon as a predictor of actual results. NON-GAAP FINANCIAL MEASURES Huttig defines Adjusted EBITDA as net income adjusted for interest, income taxes, depreciation and amortization and other special significant items. Huttig presents Adjusted EBITDA because it is a primary measure used by management, and by similar companies in the industry, to evaluate operating performance and Huttig believes it enhances investors’ overall understanding of the financial performance of our business. Additionally, Huttig defines Free Cash Flow as Adjusted EBITDA less capital expenditures.  Huttig presents Free Cash Flow because it is a meaningful indicator of cash available for the execution of Huttig’s business strategy.  Huttig defines Coverage Ratio as Adjusted EBITDA less capital expenditures divided by interest expense. The Coverage Ratio represents Huttig’s ability to meet financial obligations and its potential to fund growth opportunities. Adjusted EBITDA, Free Cash Flow, Coverage Ratio are not recognized terms under U.S. generally accepted accounting principles (“GAAP”) and do not purport to be alternatives to net income or operating cash flow as a measure of operating performance.  Huttig compensates for the limitations of using non-GAAP financial measures by using them to supplement GAAP results to provide a more complete understanding of the factors affecting the business. Because not all companies use identical calculations, Huttig’s presentation of Adjusted EBITDA, Free Cash Flow, Coverage Ratio may not be comparable to other similarly titled measures of other companies.  The table in the appendix presents a reconciliation of Adjusted EBITDA to net income (loss) attributable to Huttig for the periods indicated.
