This Amendment No.1 on Form 8-K/A (this “Amendment No.1”) is being filed to amend the Current Report on Form 8-K filed by Platform Specialty Products Corporation (“Platform”) with the Securities and Exchange Commission (the “SEC”) on January 12, 2015 (the “Original Form 8-K”).

As previously disclosed in a Current Report on Form 8-K filed with the SEC on October 21, 2014 by Platform, Platform entered into a Share Purchase Agreement with Nalozo S.à.r.l., pursuant to which Platform agreed to acquire Arysta LifeScience Limited for approximately $3.51 billion, subject to customary closing conditions (the “Arysta Acquisition”). There can be no assurance that the proposed Arysta Acquisition will close, or be completed in the time frame, on the terms or in the manner currently anticipated.

Platform voluntarily filed the Original Form 8-K with Platform’s unaudited pro forma combined consolidated balance sheet of Platform as of September 30, 2014 and the related unaudited pro forma combined consolidated statement of operations of Platform for the nine-month period ended September 30, 2014 and the year ended December 31, 2013, in each case giving effect on a pro forma basis to the Arysta Acquisition, the recent acquisition by Platform of the agrochemicals business, Chemtura AgroSolutions, of Chemtura Corporation (the “CAS Acquisition) and the related financings (the “Pro Forma Financial Information”). For the year ended December 31, 2013, the Pro Forma Financial Information was also giving effect to the acquisition of MacDermid Holdings, LLC completed on October 31, 2013 (the “MacDermid Acquisition”) and the related financings.

The purpose of this Amendment No. 1 is to amend the Original Form 8-K by filing revised Pro Forma Financial Information reflecting a $600 million increase of the aggregate principal amount of 6.500% senior notes due 2022 denominated in U.S. Dollars being offered in Platform’s previously-announced private offering of senior notes, and a $500 million decrease of the maximum borrowings under Platform’s incremental term loan denominated in U.S. Dollars being sought through the syndication process relating to the financing of a portion of the acquisition consideration and related fees and expenses of the Arysta Acquisition.

A copy of the revised Pro Forma Financial Information is attached hereto as Exhibit 99.1 and is incorporated by reference in this Item 8.01. Other than as set forth above, no other changes have been made to the Original Form 8-K. This Amendment No. 1 speaks as of the filing date of the Original Form 8-K, does not reflect events that may have occurred subsequent to the original filing date, and does not modify or update in any way disclosures made in the Original Form 8-K, except as stated above.
