Item 1.01. Entry into a Material Definitive Agreement.

 

On September 25, 2025, Cipher Mining Inc. (the “Company”) announced that its wholly owned indirect subsidiary Cipher Barber Lake LLC (“Cipher Barber Lake”) had entered into a Datacenter Lease (the “Fluidstack Lease”) with Fluidstack USA II Inc. (“Fluidstack”), which provides for the development of a data center facility on, and lease to Fluidstack of, Cipher Barber Lake’s facility (the “Facility”) located in Colorado City, Texas on the terms and subject to the conditions contained therein.

 

The Facility is expected to provide 168 megawatts (MW) of critical IT load for high-performance computing data center operations. The Company expects to complete the development and construction of the Facility and deliver the Facility to Fluidstack by September 2026. Fluidstack’s obligations to pay rent under the Fluidstack Lease begin on the commencement date of the lease and will continue for a 10-year term.

 

In connection with the Fluidstack Lease, the Company entered into the following agreements.

 

Recognition Agreements

 

On September 24, 2025, Cipher Barber Lake entered into a Recognition Agreement (the “Recognition Agreement”), among Cipher Barber Lake, Fluidstack and Google LLC (“Google”), pursuant to which Google has agreed to backstop (the “Google BackStop”) certain obligations of Fluidstack under the Fluidstack Lease, on the terms and subject to the conditions contained therein. The Google BackStop under the Recognition Agreement will become effective as of the commencement date under the Fluidstack Lease.

 

In the event of a payment default under the Fluidstack Lease, or if Fluidstack becomes subject to an insolvency event, following notice from Cipher Barber Lake, if Cipher Barber Lake and Google have not mutually agreed upon a tenant to assume the Fluidstack Lease and Recognition Agreement in place of Fluidstack within a certain specified period, Google will have the option to (i) pay all rent currently due under the Fluidstack Lease and assume the Fluidstack Lease as the tenant thereunder, (ii) under certain circumstances, pay a certain termination fee under the Fluidstack Lease; provided that upon payment of such termination fee, Google will be provided with an equity interest in Cipher Barber Lake, or (iii) under certain circumstances, defer its election of the foregoing options (i) and (ii) for a certain specified period, during which deferral period Google will pay all unpaid rent under the Fluidstack Lease and all additional rent that becomes due.

 

The description of the Recognition Agreement is qualified in its entirety by reference to the full and complete terms of the Recognition Agreement, a copy of which is filed as Exhibit 10.1 to this Report.

 

On September 24, 2025, Cipher Barber Lake entered into an additional recognition agreement with certain providers setting forth certain rights and obligations with respect to certain property to be used in the Facility in connection with the Fluidstack Lease and providing for certain cure rights in the event of a default under the Fluidstack Lease and, in certain circumstances, the right to assume the Fluidstack Lease.

 

Warrant Agreement

 

On September 24, 2025, in consideration for Google providing the Google BackStop, the Company entered into a Warrant Agreement (the “Warrant Agreement”) with Google, pursuant to which the Company issued to Google warrants (the “Warrants”) to purchase 24,178,576 shares (the “Warrant Shares”) of the Company’s common stock, par value $0.001 per share (“Common Stock”), for an exercise price of $0.01 per share of Common Stock.

 

Solely in the event that the Company does not obtain approval from its stockholders to increase the number of shares of Common Stock authorized for issuance pursuant to its Second Amended and Restated Certificate of Incorporation, the Warrants may be settled in cash in whole or in part at the election of the Company. Additionally, if, on the business day prior to the beginning of the exercise period under the Warrant Agreement, the value of the Warrant Shares does not equal or exceed $430 million, the Company shall be obligated to issue additional Warrant Shares and/or make a cash payment equal in the aggregate to such shortfall amount on the terms set forth in the Warrant Agreement.

 

 

 

As a condition to receiving the Warrants prior to the effective date applicable to the Google BackStop, Google has agreed to pledge the Warrants for the benefit of the lenders under certain financing transactions in connection with construction of the Facility pursuant to a customary warrant pledge agreement until such time as the Google BackStop becomes effective.

 

The description of the Warrant Agreement is qualified in its entirety by reference to the full and complete terms of the Warrant Agreement, a copy of which is filed as Exhibit 4.1 to this Report.

Forward Looking Statements

 

This Current Report on Form 8-K contains certain forward-looking statements within the meaning of the federal securities laws of the United States. The Company intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and includes this statement for purposes of complying with these safe harbor provisions. Any statements made in this Current Report on Form 8-K that are not statements of historical fact, such as statements about the Company’s beliefs and expectations regarding its planned business model and strategy, its bitcoin mining and HPC data center development, timing and likelihood of success, capacity, functionality and operation of data centers, expectations regarding the operations of data centers, such as projected hashrate, potential strategic initiatives, such as joint ventures and partnerships, and management plans and objectives, are forward-looking statements and should be evaluated as such. These forward-looking statements generally are identified by the words “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “seeks,” “intends,” “targets,” “projects,” “contemplates,” “believes,” “estimates,” “strategy,” “future,” “forecasts,” “opportunity,” “predicts,” “potential,” “would,” “will likely result,” “continue,” and similar expressions (including the negative versions of such words or expressions).

 

These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by Cipher and its management, are inherently uncertain. Such forward-looking statements are subject to risks, uncertainties, and other factors that could cause actual results to differ materially from those expressed or implied by such forward-looking statements. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this Current Report on Form 8-K, including but not limited to: volatility in the price of Cipher’s securities due to a variety of factors, including changes in the competitive and regulated industry in which Cipher operates, Cipher’s evolving business model and strategy and efforts it may make to modify aspects of its business model or engage in various strategic initiatives, variations in performance across competitors, changes in laws and regulations affecting Cipher’s business, and the ability to implement business plans, forecasts, and other expectations and to identify and realize additional opportunities. The foregoing list of factors is not exhaustive. Potential investors, stockholders and other readers are cautioned to carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of Cipher’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 filed with the Securities and Exchange Commission (“SEC”) on February 25, 2025, Cipher’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2025 filed with the SEC on August 7, 2025, and in Cipher’s subsequent filings with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and Cipher assumes no obligation and, except as required by law, does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise.
