On March 10, 2021, Talend S.A., a société anonyme organized under the laws of France (the “Company” or “Talend”), issued a press release announcing the execution of a Memorandum of Understanding (the “MoU”) with Tahoe Bidco (Cayman), LLC, an exempted company incorporated under the laws of the Cayman Islands (“Parent”) and an affiliate of Thoma Bravo, L.P. (“Thoma Bravo”). It is contemplated that pursuant to the MoU, Parent and the Company shall pursue a series of transactions pursuant to which, among other transactions, Parent is seeking to acquire (through one or more of its affiliates) at least 80% of the issued and outstanding ordinary shares, nominal value of €0.08 per share, of the Company (the “Company Shares”), including American Depositary Shares representing Company Shares (the “ADSs”), and Company Shares issuable upon the exercise of any outstanding options, warrant, convertible securities or rights to purchase, subscribe for, or be allocated Company Shares, pursuant to a cash tender offer (the “Offer”).

This Schedule 14D-9 filing consists of the following documents related to the proposed Offer:

The information set forth under Items 1.01, 8.01 and 9.01 of Talend’s Current Report on Form 8-K filed by the Company on March 10, 2021 (including all exhibits attached thereto) is incorporated herein by reference.

Important Additional Information and Where to Find It

In connection with the proposed acquisition of Talend S.A. (“Talend”), Tahoe BidCo B.V. (“Purchaser”) commenced a tender offer for all of the outstanding ordinary shares and American Depositary Shares (“ADSs”), each representing one ordinary share, of Talend on June 11, 2021. This communication is for informational purposes only and is neither an offer to purchase nor a solicitation of an offer to sell shares of Talend. It is also not a substitute for the tender offer materials that Purchaser filed with the Securities and Exchange Commission (the “SEC”) or the solicitation/recommendation Statement that Talend filed on Schedule 14D-9 with the SEC upon commencement of the tender offer. Purchaser filed tender offer materials on Schedule TO with the SEC, and Talend filed a Solicitation/Recommendation Statement on Schedule 14D-9 with the SEC. THE TENDER OFFER MATERIALS (INCLUDING AN OFFER TO PURCHASE, A RELATED LETTER OF TRANSMITTAL AND CERTAIN OTHER TENDER OFFER DOCUMENTS) AND THE SOLICITATION/RECOMMENDATION STATEMENT CONTAIN IMPORTANT INFORMATION THAT SHOULD BE READ CAREFULLY AND CONSIDERED BY TALEND’S STOCKHOLDERS and ADS HOLDERS BEFORE ANY DECISION IS MADE WITH RESPECT TO THE TENDER OFFER. Both the tender offer materials and the solicitation/recommendation statement are available to Talend’s stockholders and ADS holders free of charge. A free copy of the tender offer materials and the solicitation/recommendation statement will also be made available to all of Talend’s stockholders and ADS holders by contacting Talend at ir@talend.com, or by visiting Talend’s website (www.talend.com). In addition, the tender offer materials and the solicitation/recommendation statement (and all other documents filed by Talend with the SEC) are available at no charge on the SEC’s website (www.sec.gov). TALEND’S STOCKHOLDERS AND ADS HOLDERS ARE ADVISED TO READ THE TENDER OFFER MATERIALS AND THE SOLICITATION/RECOMMENDATION STATEMENT, AS EACH MAY BE AMENDED OR SUPPLEMENTED FROM TIME TO TIME, AND ANY OTHER RELEVANT DOCUMENTS FILED BY PURCHASER OR TALEND WITH THE SEC BEFORE THEY MAKE ANY DECISION WITH RESPECT TO THE TENDER OFFER. THESE MATERIALS WILL CONTAIN IMPORTANT INFORMATION ABOUT THE TENDER OFFER, PURCHASER AND TALEND.
