Each acquisition or disposition of Common Stock subsequent to the Issuer becoming a reporting company was reported on Form 4 in accordance with the rules promulgated by the SEC under Section 16 of the Securities Exchange Act of 1934, as amended.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

T. Meier and A. Meier, as officers and directors of the Issuer, are eligible to participate in the Issuer’s 2015 Incentive Plan.

In addition, in January 2014, the Issuer entered into a Note Purchase and Sale Agreement under which it agreed to purchase a loan made to Tronco Energy Corporation (“Tronco”), a party related to the Issuer through common control, in order to take over the legal position as Tronco’s senior secured lender. That agreement provided that, upon its full repayment of the Tronco loan, the lender would assign to the Issuer all of its rights under the Tronco loan, including all of the collateral documents. On May 30, 2014, the Issuer closed its purchase of the Tronco loan for a total payoff of $8.3 million, including principal, interest, and early termination fees. As a result of that purchase, the Issuer became Tronco’s senior secured lender, and as a result is entitled to receive all proceeds from sales of the Tronco-owned collateral, as discussed below.

As the result of the Issuer’s purchase of the Tronco loan, the Issuer has the direct legal right to enforce the collateral and guaranty agreements entered into in connection with the Tronco loan and to collect Tronco’s collateral sales proceeds, in order to recover the loan purchase amount. The Tronco loan continues to be secured by the first position liens on all of Tronco assets, as well as by the guarantees of T. Meier and A. Meier (the “Meier Guaranties”), which are directly payable to and legally enforceable by the Issuer. In addition, T. Meier and A. Meier have provided the Issuer with stock pledges in which they pledge all of their shares of the Common Stock held by their family entities, including MFHC and MMC (the “Meier Stock Pledge”), as collateral for their guaranties until full repayment of Tronco loan. The certificates representing the 8,814,860 pledged shares are being held in third-party escrow until full repayment of the Tronco loan.

Item 7. Material to be Filed as Exhibits.

1. Superior Drilling Products, Inc. 2015 Incentive Plan (incorporated by reference to Annex A to the Issuer’s Definitive Proxy Statement on Schedule 14A filed with the SEC on April 30, 2015).
