Amendment Description	Amarin Corporation plc is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to its Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the “Original Form 10-K Filing”), which was originally filed with the Securities and Exchange Commission (the “SEC”) on February 25, 2020, solely to set forth information required by Items 10, 11, 12, 13 and 14 of Part III of Form 10-K. This information was previously omitted from the Original Form 10-K Filing in reliance on General Instruction G.3. to the Annual Report on Form 10-K, which permits the above referenced Items to be incorporated in the Annual Report on Form 10-K by reference from a definitive proxy statement, if such proxy statement is filed no later than 120 days after December 31, 2019. At this time, we are filing this Amendment to include Part III information in our Annual Report on Form 10-K because we do not intend to file a definitive proxy statement within 120 days of December 31, 2019 due to our plans to hold our Annual General Meeting of Shareholders later in 2020 due to various logistics considerations brought on by the global pandemic known as COVID-19. This Amendment amends and restates in its entirety Items 10, 11, 12, 13 and 14 of Part III. In addition, in accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Item 15 of Part IV of the Original Form 10-K Filing has been amended solely to include as exhibits new certifications by our principal executive officer and principal financial officer. Except as described above or as expressly set forth herein, no other changes have been made to the Original Form 10-K Filing. Except as otherwise indicated herein, this Amendment does not reflect facts or events occurring after the date of the Original Form 10-K Filing or modify or update any of the other disclosures contained therein in any way other than as required to reflect the amendments discussed above. Accordingly, this Amendment should be read in conjunction with the Original Form 10-K Filing and the Company’s other filings with the SEC. References in this Amendment to “Amarin,” the “Company,” “we,” “our” and “us” refer to Amarin Corporation plc and its subsidiaries, on a consolidated basis, unless otherwise indicated.
