| Amendment Description | The purpose of this Amendment No. 1 (this “Amendment”) to the annual report of OraSure Technologies, Inc. (the “Company”) on Form 10-K for the year ended December 31, 2019, filed with the Securities and Exchange Commission (“SEC”) on March 2, 2020 (the “Original Form 10-K”), is to amend the report of KPMG LLP (“KPMG”) on the Company’s consolidated financial statements to change a reference to the date of KPMG’s audit report on the effectiveness of the Company’s internal control over financial reporting from February 28, 2020 to March 2, 2020. Such change does not affect KPMG’s unqualified opinion on the Company’s financial statements included in the Original Form 10-K. An updated consent with the current date is filed herewith as an exhibit to this Amendment. Such consent has been corrected to include a sentence related to the adoption of Accounting Standards Update (ASU) No. 2016-02, Leases, and to include a paragraph related to the exclusion of certain acquired companies from management’s assessment of the effectiveness of internal control and from KPMG’s audit of internal control over financial reporting. No other changes have been made to the Original Form 10-K. This Amendment speaks as of the filing date of the Original Form10-K, does not reflect events that may have occurred subsequent to the filing date, and does not modify or update in any way disclosures made in the Original Form 10-K, except as set forth above. This Amendment should be read in conjunction with the Original Form 10-K and the Company’s other filings made with the SEC subsequent to the filing of the Original Form 10-K. As required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended, new certifications by the Company’s Chief Executive Officer and Chief Financial Officer are also filed herewith as exhibits to this Amendment. | ||
