Item 1.01. Entry Into a Material Definitive Agreement.

On October 15, 2025, Hycroft Mining Holding Corporation (the “Company”) entered into Note Purchase and Sale Agreements (each, an “Agreement”) with each of the 17 current holders (each, a “Holder”) of the Company’s 10% Senior Secured Notes due 2027 (the “Purchased Notes”), including, but not limited to, certain funds affiliated with or managed by, Mudrick Capital Management, L.P, Whitebox Advisors, LLC, Highbridge Capital Management, LLC, and Aristeia Capital, LLC. Except for the outstanding principal balance and cash consideration amounts, all of the Agreements have substantially identical terms.

Pursuant to the Agreements, the Company agreed to repurchase the Purchased Notes from each Holder at a 9% discount to the outstanding principal balance and accrued interest. The Purchased Notes represent an aggregate outstanding principal balance of $120,817,011 plus accrued interest, and the aggregate cash consideration payable to the Holders is $110,386,797.

Upon the closing of the transactions contemplated by the Agreement (the “Closing”) and delivery of the consideration thereunder, all “Obligations” (as defined in the Agreement), including principal, accrued interest (including any paid-in-kind interest), fees and other amounts owing under the Purchased Notes, will be fully satisfied and discharged, and the Purchased Notes will be canceled in accordance with the Agreement.

The Agreements include customary representations, warranties and covenants for transactions of this type, mutual releases effective as of the Closing, and closing conditions that must be satisfied or waived. The Company agreed to reimburse the Holder for its reasonable and documented fees and expenses incurred in connection with the Agreement and the transactions contemplated thereby.

The Closing occurred on October 15, 2025.

On October 15, 2025, the Company and its guarantor subsidiaries entered into a payout letter (the “Payout Letter”) with Sprott Private Resource Lending II (Collector), LP, as lender and Sprott Resource Lending Corp., as arranger, providing for repayment in full of all obligations under the Company’s Second Amended and Restated Credit Agreement, dated as of March 30, 2022 (as amended, the “Credit Agreement”).

Under the Payout Letter, the total payoff amount as of 2:00 p.m. (Toronto time) on October 15, 2025 (the “Payout Date”) was $15,096,700.19, consisting of $15,000,000 in principal, $63,987.50 in accrued interest and fees, and $32,712.69 in lender costs and expenses, with a per diem of $4,265.83 thereafter until paid in full. Upon the lender’s receipt of the full payoff amount and the executed Payout Letter, all obligations (other than certain continuing obligations) under the Credit Agreement were satisfied and discharged, the Credit Agreement was terminated, and all related liens and security interests were released. It does not affect the Sprott Royalty or related recorded instruments, which remain in full force and effect.

The Company paid the full payoff amount on October 15, 2025.
