Copyright © 2021 Griffon Corporation. All rights reserved. Disclaimer 2 2 Cautionary Note Regarding Forward - Looking Statements This presentation contains “forward - looking statements” – statements that address future, not past events. In this context, forw ard - looking statements often address our expected future business and financial performance and financial condition, and often contain words such as “expe ct, ” “anticipate,” “intend,” “plan,” “believe,” “seek,” or “will.” Forward looking statements by their nature address matters that are, to different degrees, unce rta in. These statements are based on assumptions of future events that may not prove accurate. They are also based on our current plans and strategy and such plan s a nd strategy could change in the future. Actual results may differ materially from those projected or implied in any forward - looking statements. Please refer to our most recent SEC filings, including our 2021 Annual Report on Form 10 - K, subsequently filed Quarterly reports on Form 10 - Q, as well as our other filings with the SE C, for detailed information regarding factors that could cause actual results to differ materially from those expressed or implied in such forward - looking s tatements. We do not undertake to update our forward - looking statements. Use of Non - GAAP Financial Measures The Company provides financial measures and terms not calculated in accordance with accounting principles generally accepted in the United States (GAAP). Presentation of non - GAAP measures such as, but not limited to, “free cash flow,” “segment adjusted EBITDA,” “compliance adjusted EBITDA” and “adjusted EBITDA” provide investors with an alternative method for assessing our operating results in a manner that enables them to mor e t horoughly evaluate our performance. The non - GAAP measures included in this presentation are provided to give investors access to the types of measures that we use in analyzing our results. The Company’s calculation of non - GAAP financial measures is not necessarily comparable to similarly titled measures reported by other companies. These non - GAAP measures may be considered in addition to results prepared in accordance with GAAP, but should not be considered a subst itu te for or superior to GAAP results. A reconciliation of GAAP to non - GAAP measures appear on slides 51 and 52. A copy of this presentation, including the reconciliation of GAAP to non - GAAP measures, is available on our website www.griffon. com.
