EXPLANATORY NOTE

This Amendment No. 1 is being filed in order to correct a typographical error in the Current Report filed by the Registrant as of June 2, 2016 (the “Original Form 8-K”) with respect to the definition of the “End Date”. No other information in the Original Form 8-K is amended hereby.

On June 2, 2016, Qlik Technologies Inc. (the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Project Alpha Holding, LLC (“Parent”) and Project Alpha Merger Corp., a wholly owned subsidiary of Parent (“Merger Sub”), providing for the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. Parent and Merger Sub were formed by an affiliate of private equity investment firm Thoma Bravo, LLC (“Thoma Bravo”). Capitalized terms not otherwise defined have the meaning set forth in the Merger Agreement.

At the Effective Time of the Merger, each share of common stock, par value $0.0001 per share, of the Company (the “Company Common Stock”) issued and outstanding as of immediately prior to the Effective Time (other than Dissenting Shares or shares owned by Parent or Merger Sub) will be cancelled and extinguished and automatically converted into the right to receive cash in an amount equal to $30.50, without interest thereon (the “Per Share Price”).

Parent and Merger Sub have secured committed financing, consisting of a combination of equity to be provided by investment funds affiliated with Thoma Bravo and debt to be provided by Ares Capital Corporation, Golub Capital LLC, TPG Special Situations Partners and Varagon Capital Partners, L.P., the aggregate proceeds of which, together with cash on the Company’s balance sheet, will be sufficient for Parent and Merger Sub to pay the aggregate merger consideration and all related fees and expenses. Parent and Merger Sub have committed to use their reasonable best efforts to obtain the debt financing on the terms and conditions described in the debt commitment letter entered into as of June 2, 2016 (which debt commitment letter expires on October 31, 2016). The transaction is not subject to a financing condition.

Consummation of the Merger is subject to customary closing conditions, including, without limitation, the absence of certain legal impediments, the expiration or termination of the required waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, the receipt of certain foreign antitrust approvals, and approval by the Company’s stockholders. In addition, consummation of the Merger is subject to completion of a customary marketing period with regard to the debt financing.

The Company has made customary representations and warranties in the Merger Agreement and has agreed to customary covenants regarding the operation of the business of the Company and its Subsidiaries prior to the Effective Time. The Company is also subject to customary restrictions on its ability to solicit alternative acquisition proposals from third parties and to provide non-public information to, and participate in discussions and engage in negotiations with, third parties regarding alternative acquisition proposals, with customary exceptions for Superior Proposals.

The Merger Agreement contains certain termination rights for the Company and Parent. Upon termination of the Merger Agreement under specified circumstances, the Company will be required to pay Parent a termination fee of $103 million. Such circumstances include where the Merger Agreement is terminated in connection with the Company accepting a Superior Proposal, due to the Company Board’s change or withdrawal of its recommendation of the Merger or due to the Company materially breaching its obligations regarding solicitation of alternative acquisition proposals. This termination fee will also be payable if the Merger Agreement is terminated because the Company’s stockholders did not vote to adopt the Merger Agreement and prior to such termination, a proposal to acquire at least 50.1% of the Company’s stock or assets is publicly announced and the Company enters into an agreement for, or completes, a transaction contemplated by such proposal within one year of termination. In addition, the Company will be required to reimburse Parent for up to $5 million of its expenses associated with the transaction if the Merger Agreement is terminated because the Company’s stockholders do not vote to adopt the

Merger Agreement or if the Company breaches its representations, warranties or covenants in a manner that would cause the related closing conditions to not be met, in each case where the termination fee is not then payable but could potentially become payable in the future under certain circumstances.

Upon termination of the Merger Agreement under other specified circumstances, Parent will be required to pay the Company a termination fee of $207 million. The termination fee by Parent will become payable if Parent fails to consummate the Merger after certain conditions are met, if Parent breaches its representations, warranties or covenants in a manner that would cause the related closing conditions to not be met, or if either party terminates because the termination has not been consummated by the End Date (described below), and at the time of such termination, the Company was otherwise entitled to terminate the Agreement for either of the above reasons. Thoma Bravo has provided the Company with a limited guaranty in favor of the Company (the “Limited Guarantee”). The Limited Guarantee guarantees the payment of the termination fee payable by Parent. The Merger Agreement also provides that either party may specifically enforce the other party’s obligations under the Merger Agreement, provided that the Company may only cause Parent to close the transaction if certain conditions are satisfied, including the funding or availability of the debt financing.

In addition to the foregoing termination rights, and subject to certain limitations, the Company or Parent may terminate the Merger Agreement if the Merger is not consummated by October 31, 2016 (the “End Date”).

Company stock options, stock appreciation rights and vested Company restricted stock units will generally be cancelled at the Effective Time and converted into the right to receive the Per Share Price (less applicable withholding and any applicable exercise price or base price in the case of options and stock appreciation rights) promptly following the Effective Time. Each grant of Company restricted stock units which is unvested as of the Effective Time will be cancelled at that time and converted into the right to receive the Per Share Price with respect to each share of Company Common Stock subject thereto, with such payment being made promptly following the Effective Time with respect to one-third of each unvested grant and with respect to the remaining two-thirds of each such grant in equal portions promptly following the twelve and eighteen month anniversaries of the Effective Time (or upon such earlier date as the Company restricted stock unit was otherwise scheduled to vest).

In connection with the execution of the Merger Agreement, which has been unanimously approved by the Company Board and recommended for approval to the Company’s shareholders, Parent has entered into voting agreements (the “Voting Agreements”) with the directors and certain officers of the Company (collectively, the “Shareholders”), which collectively hold approximately 1.3% of the outstanding shares of Company Common Stock. Under the Voting Agreements the Shareholders agree, during the term of the Voting Agreements, to vote their shares of Company Common Stock (i) in favor of the adoption of Merger Agreement and the approval of the transactions contemplated thereby and (ii) against any alternative acquisition proposal, and not to, directly or indirectly, sell, transfer, exchange or otherwise dispose of the their shares, subject to certain limited exceptions.

The representations, warranties and covenants of the Company contained in the Merger Agreement have been made solely for the benefit of Parent and Merger Sub. In addition, such representations, warranties and covenants (i) have been made only for purposes of the Merger Agreement, (ii) have been qualified by (a) subject to certain terms and conditions, matters specifically disclosed in the Company’s filings with the SEC prior to the date of the Merger Agreement and (b) confidential disclosures made to Parent and Merger Sub in the disclosure letter delivered in connection with the Merger Agreement, (iii) are subject to materiality qualifications contained in the Merger Agreement which may differ from what may be viewed as material by investors, (iv) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement and (v) have been included in the Merger Agreement for the purpose of allocating risk between the contracting parties rather than establishing matters as fact. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the Company or its business.

Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company or any of its subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public

disclosures. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the Company that is or will be contained in, or incorporated by reference into, the Annual Reports on Form 10-K, Current Reports on Form 10-Q and other documents that the Company files with the SEC.

The foregoing description of the Merger Agreement, the Voting Agreements and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement and the form of Voting Agreement, copies of each of which are attached hereto as Exhibit 2.1 and 99.1, and the terms of which are incorporated herein by reference.

On June 2, 2016, the Board of Directors of the Company approved an amendment to the Amended and Restated Bylaws of the Company (the “Bylaw Amendment”), which became effective immediately. The Bylaw Amendment added a new Section 7.9 that designates the state and federal courts located within the state of Delaware as the sole and exclusive forum for certain legal action, unless the Company consents in writing to the selection of an alternative forum. The foregoing description of the Bylaw Amendment is only a summary, does not purport to be complete, and is qualified in its entirety by reference to the Bylaw Amendment, a copy of which is attached as Exhibit 3.1 and is incorporated herein by reference.

INVESTORS AND SECURITY HOLDERS OF THE COMPANY ARE URGED TO READ THESE MATERIALS (INCLUDING ANY AMENDMENTS OR SUPPLEMENTS THERETO) AND ANY OTHER RELEVANT DOCUMENTS IN CONNECTION WITH THE MERGER THAT THE COMPANY WILL FILE WITH THE SEC WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT THE COMPANY AND THE MERGER.

Forward-looking statements

All of the statements in this Current Report on Form 8-K, other than historical facts, are forward-looking statements made in reliance upon the safe harbor of the Private Securities Litigation Reform Act of 1995, including, without limitation, the statements made concerning the Company’s intent to consummate a merger with an affiliate of Thoma Bravo. As a general matter, forward-looking statements are those focused upon anticipated events or trends, expectations, and beliefs relating to matters that are not historical in nature. Such forward-looking statements are subject to uncertainties and factors relating to the Company’s operations and business environment, all of which are difficult to predict and many of which are beyond the control of the Company. Among others, the following uncertainties and other factors could cause actual results to differ from those set forth in the forward-looking statements: (i) the risk that the Merger may not be consummated in a timely manner, if at all; (ii) the risk that the Merger may not be consummated as a result of Parent’s failure to obtain financing and that, in certain circumstances, the Company may not be entitled to a termination fee; (iii) the risk that the definitive Merger Agreement may be terminated in circumstances that require the Company to pay a termination fee; (iv) risks related to the diversion of management’s attention from the Company’s ongoing business operations; (v) risks regarding the failure of the relevant Thoma Bravo affiliate to obtain the necessary financing to complete the Merger; (vi) the effect of the announcement of the Merger on the Company’s business relationships (including, without limitation, customers and suppliers), operating results and business generally; and (vii) risks related to obtaining the requisite consents to the merger, including, without limitation, the timing (including possible delays) and receipt of regulatory approvals from various domestic and foreign governmental entities (including any conditions, limitations or restrictions placed on these approvals) and the risk that one or more governmental entities may deny approval. Further risks that could cause actual results to differ materially from those matters expressed in or implied by such forward-looking statements are described in the Company’s SEC reports, including but not limited to the risks described in the Company’s Annual Report on Forms 10-K for its fiscal year ended December 31, 2015 and Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2016. The Company assumes no obligation and does not intend to update these forward-looking statements.
