VENLO, the Netherlands, January 9, 2019 – QIAGEN N.V. (NYSE: QGEN; Frankfurt Prime Standard: QIA) hereby informs in response to queries from certain market participants, and following consultation with the Calculation Agent, holders of the following clarification with respect to the Notes:

When determining the Daily VWAP in respect of any of the 2019 Notes, the 2021 Notes, or the 2023 Notes, for so long as the Relevant Exchange is the New York Stock Exchange (NYSE), or until and unless the Calculation Agent determines otherwise in its sole discretion (in accordance with the definition of “Daily VWAP”), the Calculation Agent will observe the Daily VWAP on the Bloomberg page “QGEN US <equity> AQR”, using “09:30:00” (Local Time) as the start time input for the scheduled opening of trading and “16:00:00” (Local Time) as the end time. For the avoidance of doubt, (i) the Calculation Agent will also use these settings, in accordance with the Indenture, for the 2024 Notes, and (ii) the use of these time settings would normally be expected to result in the inclusion of the trades which occur in the opening auction, and the exclusion of trades which occur in the closing auction of the Common Stock on the New York Stock Exchange, consistent with the fact that the NASDAQ opening cross would have been included and the NASDAQ closing cross would have been excluded, had the same time settings been used (pursuant to the definition of “Daily VWAP”) whilst the Relevant Exchange was The NASDAQ Global Select Market (having been the Relevant Exchange at the date of issuance of the 2019 Notes, the 2021 Notes, and the 2023 Notes).
