In this presentation, we discuss events or results that have not yet occurred or been realized, commonly referred to as “forward - looking statements” within the meaning of the federal securities laws, including statements regarding the impact of the acquisitions by Platform Specialty Products Corporation (“Platform”) of Percival S.A, including its agrochemical business, Agriphar (“ Agriphar ”), the Chemtura AgroSolutions business of Chemtura Corporation (“ Chemtura AgroSolutions ” or “CAS ”), Arysta LifeScience Limited. (“ Arysta ”), as well as the proposed acquisition by Platform of the Electronic Chemicals and Photomasks businesses (the “EC and PM businesses”) of OM Group, Inc. (the “OMG Acquisition”) and the proposed offer by Platform to acquire the entire issued and to be issued share capital of Alent ( the “ Alent Acquisition”) on the business and financial results of Platform, including sales, adjusted EBITDA, capital expenditures, cash flows, earnings per share, expected or estimated revenue, the outlook for Platform’s markets and the demand for its products, estimated sales, segment e arn ings, net interest expense, income tax provision, restructuring and other charges, cash flows from operations, consistent profitable growth, free cash fl ow, future revenues and gross operating and adjusted EBITDA margin improvement requirement and expansion, organic net sales growth, bank debt covenants, the success of new product introductions, growth in costs and expenses, the impact of commodities and currencies and Platform’s ability to manage its risk in these are as, Platform’s ability to raise new debt or equity and to consummate acquisitions, estimated synergies in Platform’s new combined agrochemical businesses, and relating to the OMG Acquisition or Alent Acquisition, and the impact in general of acquisitions, divestitures, restructurings, and other unusual items, including Platform's abilit y t o successfully integrate and obtain the anticipated results and synergies from its consummated and future acquisitions. These statements are based on management's estimates and assumptions with respect to future events and financial performance and are believed to be reasonable, though are inherently uncertain and difficult to predict. Actual results could differ materially from those proje cte d as a result of certain factors. A discussion of factors that could cause results to vary is included in Platform’s registration statement filed with the Securities and Exchange Commission (the “SEC”) on June 17, 2015, as amended, and periodic and other reports filed by Platform with the SEC, including under the heading “Risk Factors” in Platform’s Annual Report on Form 10 - K for the fiscal year ended December 31, 2014. Platform undertakes no obligation to update any forward - looking statement, whether as a result of new information, future events or otherwise. This presentation also contains non - GAAP financial measures that may not be directly comparable to other similarly titled measur es used by other companies, including EBITDA and adjusted EBITDA. For purposes of Regulation G, a non - GAAP financial measure is a numerical measure of a company’s historical or future financial performance, financial position or cash flows that excludes amounts, or is subject to adjustments that have the eff ect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statements of operat ion s, balance sheets, or statements of cash flows of such company; or includes amounts, or is subject to adjustments that have the effect of including am ounts, that are excluded from the most directly comparable measure so calculated and presented. Pursuant to the requirements of Regulation G, Platform has prov ide d reconciliations of the non - GAAP financial measures to the most directly comparable GAAP financial measures in the Appendix of this presentation. These n on - GAAP measures are provided because management of Platform uses these financial measures in monitoring and evaluating Platform’s ongoing financial result s a nd trends. Management uses this non - GAAP information as an indicator of business performance, and evaluates overall management with respect to such indicat ors. These non - GAAP measures should be considered in addition to, but not as a substitute for, measures of financial performance prepared in acco rda nce with GAAP. Historical financial information relating to Agriphar was obtained directly from Percival S.A., its privately - held former parent company. Although we believe it is reliable, this information has not been verified, internally or independently. Historical financial information relating to Chemtura AgroSolutions was derived from segment reporting in Chemtura Corporation’s periodic reports and earnings press releases. Financial information for Arysta was derived from Arysta’s registration statement on Form F - 1 filed with the SEC on September 9, 2014, which was withdrawn since Platform’s acquisition of Arysta and should not be relied upon, and from Arysta’s management . Historical financial information related to the EC and PM businesses of OM Group, Inc. was derived from OM Group, Inc.’s management estimates. T he EC and PM businesses’ method of calculating their Adjusted EBITDA differs from Platform’s method of calculating Adjusted E BIT DA. Historical financial information for Alent was derived from Alent’s periodic reports and management estimates. Alent’s method of calculating its Adjusted EBITDA also differs from Platform’s method. In addition, Alent’s financial information is prepared in accordance with non - GAAP that may or may not be comparable to Platform’s financial statements. Consequently, there is no assurance that the financial results and information for Agriphar , Chemtura AgroSolutions , Arysta, the EC and PM businesses, or Alent contained in this presentation are accurate or complete, or representative in any way of Platform’s actual and future results as a consolidated company.
