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

The information contained in Item 4 of this Schedule 13D is incorporated herein by reference.

The reported securities herein were obtained in connection with the Business Combination involving the Issuer and another issuer that occurred on May 29, 2020. On May 29, 2020, the Issuer (Hycroft Mining Holding Corporation, formerly known as Mudrick Capital Acquisition Corporation) consummated the transactions contemplated by a Purchase Agreement, dated as of January 13, 2020, by and among the Issuer, MUDS Acquisition Sub, Inc. (“Acquisition Sub”) and Hycroft Mining Corporation (“Seller”), as amended (the “Purchase Agreement”). Pursuant to the Purchase Agreement, Acquisition Sub acquired all of the issued and outstanding equity interests of the direct subsidiaries of Seller and substantially all of the other assets and assumed substantially all of the liabilities of Seller, a US-based gold and silver producer operating the Seller’s mine located in the mining region of northern Nevada. The foregoing descriptions of the Business Combination and the Purchase Agreement do not purport to be complete and are subject to and qualified in their entirety by reference to the Issuer’s 8-K12B filed on June 4, 2020 and Exhibit 2.1 of the Issuer’s 8-K filed on January 14, 2020, which are incorporated by reference as Exhibit 5 and Exhibit 6 hereto, respectively.

On January 13, 2020, the Issuer entered into subscription/backstop agreements (the “Subscription/Backstop Agreements”) with certain investment funds or entities affiliated with or managed by WA, including WBox serving as the investment funds’ collateral agent, and other advisers (collectively, the “Initial Investors”), pursuant to which the Issuer issued and sold to the Initial Investors $65,000,000 of the Issuer’s Common Stock at a purchase price of $10.00 per share, and the Initial Investors received an aggregate of 3,250,000 warrants (the “PIPE Warrants”) exercisable at $11.50 per share, in each case, in connection with the consummation of the Business Combination. Reference is made to the Issuer’s 8-K and Exhibit 10.1 attached thereto filed on January 14, 2020, which is incorporated by reference as Exhibit 7 hereto.

Each PIPE Warrant gives the holder thereof the right to purchase one share of Common Stock, subject to certain exceptions. The PIPE Warrants will become exercisable on June 28, 2020 and expire May 29, 2025 or earlier upon their redemption or the liquidation of the Issuer. Once exercisable, the PIPE Warrants may be redeemed, at a price of $0.01 per warrant, if the last sale price of the Common Stock equals or exceeds $18.00 per share for any 20 trading days within a 30 trading day period ending on the third business day before the notice of redemption is sent to the warrant holders. The foregoing description of the PIPE warrants does not purport to be complete and is subject to and qualified in its entirety by reference to the Warrant Agreement included as Exhibit 4.3 of the Issuer's 8-K12B filed on June 4, 2020, which is incorporated by reference as Exhibit 8 hereto.
