Item 1.01 Entry into a Material Definitive Agreement.

On October 6, 2016, Frank’s International N.V. (the “Company”) announced that it has entered into a definitive merger agreement (“Merger Agreement”) to acquire Blackhawk Group Holdings, Inc. (“Blackhawk”). Blackhawk is the ultimate parent of Blackhawk Specialty Tools LLC, a leading provider of well construction and well intervention services and products. Certain investment funds affiliated with Bain Capital Partners LLC (collectively “Bain Capital”) currently own approximately 70% of the capital stock of Blackhawk. Concurrently with the execution and delivery of the Merger Agreement, Bain Capital and other stockholders of Blackhawk delivered a written consent adopting the Merger Agreement with respect to the shares of Blackhawk capital stock owned by them.

Pursuant to the Merger Agreement, by and among the Company, FI Tools Holdings, LLC, a newly-formed subsidiary of the Company (“Merger Sub”), Blackhawk and Bain Capital Private Equity, LP, solely in its capacity as stakeholder representative, Merger Sub will merge with and into Blackhawk, with Blackhawk surviving the Merger as a wholly-owned subsidiary of the Company. The merger consideration comprises a combination of approximately $150 million of cash on hand and approximately 12.8 million shares of the Company’s common stock (“Common Stock”), on a cash-free, debt-free basis (with approximately $80.0 million of Blackhawk debt being repaid at closing with proceeds from the transaction). The maximum number of shares of Common Stock to be issued upon the consummation of the Merger will be reduced or otherwise adjusted based on (i) the amount of cash paid to non-accredited investors and certain other Blackhawk stockholders (who will receive cash in lieu of Common Stock) and the holders of in-the-money options to acquire Blackhawk common stock (which will be cancelled at the effective time of the Merger) and (ii) post-closing working capital adjustments. It is anticipated that the closing of the transaction will occur during the fourth quarter of 2016.

If the closing occurs, the Company will place certain of the shares of Common Stock comprising the equity consideration in escrow as partial security for Blackhawk’s indemnity obligations under the Merger Agreement, which include indemnities for the benefit of the Company for breaches of Blackhawk’s representations, warranties and covenants and certain other matters (subject to certain limitations). The Merger Agreement contains caps on certain losses arising under the Merger Agreement of up to approximately 17% of the aggregate transaction value. Such caps do not apply to fraud or intentional misconduct. Portions of the escrow will also apply to post-closing working capital adjustments.

The completion of the Merger is subject to a number of closing conditions, including among others, (i) the expiration or termination of applicable U.S. anti-trust laws and the waiting period and receipt of Brazilian merger control approvals, (ii) subject to certain exceptions, the accuracy of the representations and warranties and material compliance with covenants, (iii) the absence of any event, circumstance or change that would have a material adverse effect on Blackhawk and (iv) delivery of various closing documentation. The Merger Agreement also contains certain termination rights for both the Company and Blackhawk, including a right to terminate if the Merger is not consummated by December 5, 2016 (subject to certain exceptions).

In connection with the delivery of shares of Common Stock at closing, the Company will enter into a Registration Rights Agreement with Bain Capital and certain other stockholders of Blackhawk, pursuant to which, among other things, the Company will register the resale of the shares of Common Stock issued to such stockholders of Blackhawk. In addition, Bain Capital will have certain demand registration rights with respect to underwritten offerings that may be undertaken by Bain Capital following the closing. In connection with the grant of these demand rights, the Company has agreed to seek waivers from certain stockholders who were previously granted certain piggyback registration rights pursuant to that certain registration rights agreement, dated August 14, 2013. If the Company is unable to obtain the requisite approvals for such waiver and the holders of the pre-existing piggyback registration rights exercise those rights in respect of an underwritten offering by Bain Capital, the Company has agreed to either (i) repurchase a number of shares of Common Stock from Bain Capital equal to $50M less any shares actually sold by Bain Capital in its underwritten offering (such repurchase may be funded through a primary issuance of shares of Common Stock by the Company, in its discretion) or (ii) purchase such number of shares of Common Stock from the pre-existing holders of the piggyback registration rights such that Bain Capital would no longer be required to reduce the number of shares it proposed to include in its underwritten offering below $50M. All expenses incident to such registrations will be borne by the Company.

The Merger Agreement and related transaction documents contain representations, warranties, covenants and conditions customary for a transaction of this nature. The representations and warranties set forth in the Merger Agreement and related transaction documents were made by the parties to each other as of specific dates and to evidence their agreement on various issues, and were made solely for purposes of the Merger and may be subject to important qualifications and limitations or other factors agreed to by the parties in connection with negotiating the terms of the Merger. Based on the foregoing, you should not rely on the representations, warranties and disclosures included in the Merger Agreement or related transaction documents as statements of fact.

Item 3.02 Unregistered Sales of Equity Securities.

The issuance of the shares of Common Stock is expected to be exempt from registration as a private placement under Section 4(a)(2) of the Securities Act of 1933, as amended, and Rule 506 promulgated thereunder, among other exemptions. The Company has not engaged in general solicitation or advertising with regard to the issuance and sale of shares of Common Stock to be issued in the Merger.

The information disclosed in Item 1.01 of this Current Report on Form 8-K is incorporated into this Item 3.02 by reference and the disclosure in this Item 3.02 is qualified by reference to the information set forth in Item 1.01 of this Current Report on Form 8-K.

Item 8.01 Other Events

On October 7, 2016, the Company issued a press release announcing the execution of the Merger Agreement. The press release is attached as Exhibit 99.1 and is incorporated by reference herein.
