**1 Vanderbilt Avenue, Floor 54**

**New York, New York 10017** 

**PROXY STATEMENT** 

**FOR THE SPECIAL MEETING OF STOCKHOLDERS** 

**TO BE HELD ON October ____, 2025** 

This proxy statement (this "Proxy Statement") including the appendices hereto and related materials (together with this Proxy Statement, the "proxy materials") are being furnished by and on behalf of the board of directors (the "Board" or "Board of Directors") of Cipher Mining Inc. (the "Company," "Cipher," "we," "us," or "our"), in connection with our special meeting of stockholders (the "Special Meeting"). The Notice of Special Meeting and this Proxy Statement are first being distributed or made available, as the case may be, on or about October ____, 2025.

**GENERAL INFORMATION ABOUT THE SPECIAL MEETING AND VOTING** 

**When and where will the Special Meeting be held?** 

The Special Meeting will be held on October ____, 2025 at 8:00 a.m., Eastern Time. The Special Meeting will be a completely virtual meeting, which will be conducted via live webcast. You will be able to attend the Special Meeting online and submit your questions during the meeting by visiting *www.virtualshareholdermeeting.com/CIFR2025SM* and entering your 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials. If you lose your 16-digit control number, you may join the Special Meeting as a "Guest" but you will not be able to vote or ask questions.

**What are the purposes of the Special Meeting?** 

The purpose of the Special Meeting is to vote to approve an amendment to the Company's Second Amended and Restated Certificate of Incorporation to increase the number of shares of common stock, par value $0.001 per share ("Common Stock") authorized for issuance from 500,000,000 to 1,000,000,000 shares (the "Charter Amendment" and such proposal, the "Charter Amendment Proposal").

**Are there any matters to be voted on at the Special Meeting that are not included in this Proxy Statement?** 

At the date of this Proxy Statement, we did not know of any matters to be properly presented at the Special Meeting other than those referred to in this Proxy Statement. If other matters are properly presented at the meeting or any adjournment, continuation or postponement thereof for consideration, and you are a stockholder of record and have submitted a proxy card, the persons named as proxies on your proxy card will have the discretion to vote on those matters for you.

**What does it mean if I receive more than one set of proxy materials?** 

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each set of proxy materials, please submit your proxy by phone, via the Internet, or by signing, dating and returning the enclosed proxy card in the enclosed envelope.

**Who is entitled to vote at the Special Meeting?** 

Holders of record of shares of our common stock as of the close of business on September 12, 2025 (the "Record Date") will be entitled to notice of and to vote at the Special Meeting and any continuation, postponement or adjournment thereof. At the close of business on the Record Date, there were 393,286,007 shares of our common stock issued and outstanding and entitled to vote. Each share of our common stock is entitled to one vote on any matter presented to stockholders at the Special Meeting.

------

**<u>[**Table of Contents**](#i1595b230957b454db5a3ff6369fa417d_16)</u>**

To attend and participate in the Special Meeting, you will need the 16-digit control number included in your Notice and Access Card, on your proxy card or on the instructions that accompanied your proxy materials. If your shares are held in "street name," you should contact your bank or broker to obtain your 16-digit control number or otherwise vote through the bank or broker. If you lose your 16-digit control number, you may join the Special Meeting as a "Guest" but you will not be able to vote or ask questions. The meeting webcast will begin promptly at 8:00 a.m., Eastern Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 7:45 a.m., Eastern Time, and you should allow ample time for the check-in procedures.

**What is the difference between being a "record holder" and holding shares in "street name"?** 

A record holder (also called a "registered holder") holds shares in his or her name. Shares held in "street name" means that shares are held in the name of a bank, broker or other nominee on the holder's behalf.

**How do I vote if my shares are held in "street name"?** 

If your shares are held in a brokerage account or by a bank or other holder of record, you are considered the "beneficial owner" of shares held in "street name." In this case, the proxy materials have been forwarded to you by your broker, bank or other nominee who is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your broker, bank or other holder of record on how to vote your shares by following their instructions for voting. Please refer to information from your bank, broker or other nominee on how to submit your voting instructions. To participate in the Special Meeting online at www.virtualshareholdermeeting.com/CIFR2025SM, you will need the sixteen-digit control number included on your proxy card or the instructions that accompanied your proxy materials. If you did not receive a control number, please contact your bank or broker directly.

**How many shares must be present to hold the Special Meeting?** 

A quorum must be present at the Special Meeting for any business to be conducted. The holders of a majority in voting power of the Company's capital stock issued and outstanding and entitled to vote, present electronically or represented by proxy constitutes a quorum. If you sign and return your paper proxy card or authorize a proxy to vote electronically or telephonically, your shares will be counted to determine whether we have a quorum even if you abstain or fail to vote as indicated in the proxy materials.

Broker non-votes will also be considered present for the purpose of determining whether there is a quorum for the Special Meeting.

**What are "broker non-votes"?** 

A "broker non-vote" occurs when shares held by a broker in "street name" for a beneficial owner are not voted with respect to a proposal because (1) the broker has not received voting instructions from the stockholder who beneficially owns the shares and (2) the broker lacks the authority to vote the shares at their discretion. Under the applicable rules, the Charter Amendment Proposal is a "routine" matter. Accordingly, brokers, banks or other nominees can vote on this proposal without instructions from beneficial owners and there will not be any broker non-votes in respect of this proposal.

**What if a quorum is not present at the Special Meeting?** 

If a quorum is not present or represented at the scheduled time of the Special Meeting, (i) the chairperson of the Special Meeting or (ii) a majority in voting power of the stockholders entitled to vote at the Special Meeting, present in person or electronically, if applicable, or represented by proxy, may adjourn the Special Meeting until a quorum is present or represented.

**How do I vote my shares before the Special Meeting?** 

We recommend that stockholders vote by proxy prior to the Special Meeting even if they plan to attend the Special Meeting. If you are a stockholder of record, there are three ways to vote by proxy:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• by Internet—You can vote over the Internet at *www.proxyvote.com* by following the instructions on the Notice and Access Card or proxy card;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• by Telephone—You can vote by telephone by calling 1-800-690-6903 and following the instructions on the proxy card; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• by Mail—You can vote by mail by signing, dating and mailing the proxy card, which you may have received by mail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• related to any pending, threatened or ongoing litigation;

**How does the Board recommend that I vote?** 

The Board recommends that you vote **FOR** the Charter Amendment Proposal.

**How many votes are required to approve the Charter Amendment Proposal?** 

The table below summarizes the proposal that will be voted on, the vote required to approve the proposal and how votes are counted:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Proposal** | **Votes Required For Approval** | **Voting Options** | **Effect of<br>"Abstain" Votes** | **Effect of Broker Non-Votes** |
| Charter Amendment Proposal | Pursuant to Delaware law, the votes cast for the Charter Amendment Proposal must exceed the votes cast against the Charter Amendment Proposal. | "FOR"<br>"AGAINST"<br>"ABSTAIN" | None. <sup>(1)</sup> | Not applicable.<sup>(2)</sup> |

---

(1)Abstentions are not counted as votes cast and thus will have no effect on the vote on this proposal.

(2)As this proposal is considered a discretionary matter, brokers are permitted to exercise their discretion to vote uninstructed shares on this proposal, and we do not expect any broker non-votes on this matter.

**What if I do not specify how my shares are to be voted?** 

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board's recommendations are set forth above, as well as with the description of each proposal in this Proxy Statement.

**Who will count the votes?** 

Representatives of Broadridge Investor Communications Services ("Broadridge") will tabulate the votes, and a representative of Broadridge will act as inspector of election.

**Can I revoke or change my vote after I submit my proxy?** 

Yes. Whether you have voted by Internet, telephone or mail, if you are a stockholder of record, you may change your vote and revoke your proxy by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sending a written statement to that effect to the attention of our Corporate Secretary at our corporate offices, provided such statement is received no later than [_____], 2025;

------

**<u>[**Table of Contents**](#i1595b230957b454db5a3ff6369fa417d_16)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• voting again by Internet or telephone at a later time before the closing of those voting facilities at 11:59 p.m., Eastern Time, on [_____], 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• submitting a properly signed proxy card with a later date that is received no later than [_____], 2025; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• attending and voting at the Special Meeting, which will revoke your prior proxy.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by contacting your bank or broker, or you may vote electronically during the Special Meeting by obtaining your 16-digit control number from your bank or broker or otherwise voting through your bank or broker.

Your most recent proxy card or telephone or Internet proxy is the one that is counted. Your attendance at the Special Meeting by itself will not revoke your proxy unless you give written notice of revocation to the Company before your proxy is voted or you vote online at the Special Meeting.

**Who will pay for the cost of this proxy solicitation?** 

We will pay the cost of soliciting proxies. Proxies may be solicited on our behalf by directors, officers or employees (for no additional compensation) in person or by telephone, electronic transmission and facsimile transmission. Brokers and other nominees will be requested to solicit proxies or authorizations from beneficial owners and will be reimbursed for their reasonable expenses.

**Do stockholders have any dissenters' rights with regards to the matters proposed to be acted upon?** 

There are no rights of appraisal or other similar rights of dissenters under the laws of the State of Delaware with respect to any of the matters proposed to be acted upon herein.

**CHARTER AMENDMENT PROPOSAL - INCREASE IN AUTHORIZED SHARES**

**Purpose of the Charter Amendment** 

We are asking you to adopt an amendment to the Company's Second Amended and Restated Certificate of Incorporation, which is attached to this Proxy Statement as Appendix A, to increase the number of shares of our Common Stock authorized for issuance from 500,000,000 to 1,000,000,000. The Board believes it is in the best interest of the Company to increase the number of authorized shares of Common Stock to provide the Company with the flexibility to issue additional shares of Common Stock for a variety of corporate purposes without the delay and expense of seeking stockholder approval at a future special meeting. These purposes may include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Facilitating strategic partnerships, joint ventures or other collaborative arrangements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Financing growth initiatives and capital expenditures through equity or equity-linked offerings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Providing equity incentives to employees, officers and directors pursuant to the Company's compensation plans; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Other general corporate purposes approved by the Board.

**Recent Developments** 

In September 2025, the Company (i) issued warrants to Google LLC ("Google") exercisable for shares of Common Stock,in connection with a ten-year data center lease agreement with Fluidstack USA I Inc., supported by a financial backstop from Google; and (ii) [issued] convertible senior notes, which are required to be settled in cash until the Company increases the number of its shares of Common Stock authorized for issuance.

As a result of these transactions, the Company has limited remaining capacity to issue shares of Common Stock under its current authorization. The Charter Amendment is intended to restore flexibility for the Company to issue additional Common Stock to support future strategic partnerships, site expansions, acquisitions, financing transactions and equity incentive programs, and to ensure the Company maintains sufficient capacity to pursue growth opportunities and enhance long-term stockholder value.

The full text of the Charter Amendment attached to this Proxy Statement as Appendix A is incorporated herein by reference.

**Board Recommendation** 

The Board of Directors unanimously recommends that stockholders vote **FOR** the approval of the Charter Amendment Proposal.

If the Charter Amendment Proposal is approved by the requisite number of our stockholders, we expect to file the approved Charter Amendment with the Secretary of State of the State of Delaware promptly after the Special Meeting, which will become effective at the time of the filing.

Notwithstanding the foregoing, at any time prior to the effectiveness of the filing of an approved charter amendment with the Secretary of State of the State of Delaware, our Board reserves the right to abandon the approved charter amendment and not to file the charter amendment, even if the Charter Amendment is approved by our stockholders, if our Board, in its discretion, determines that the approved Charter Amendment is no longer in the best interests of our Company or our stockholders.

If the Charter Amendment Proposal is not approved by the requisite vote of our stockholders, then the Charter Amendment will not be filed with the Secretary of State of the State of Delaware and our current Second Amended and Restated Certificate of Incorporation will remain in place and our number of authorized shares will remain unchanged.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• all directors and executive officers as a group.

**STOCKHOLDER PROPOSALS AND DIRECTOR NOMINATIONS** 

Stockholders who intend to have a proposal considered for inclusion in our proxy materials for presentation at our annual meeting of stockholders to be held in 2026 (the "2026 Annual Meeting") pursuant to Rule 14a-8 under the Exchange Act must submit the proposal to our Secretary at our offices at 1 Vanderbilt Avenue, Floor 54, New York, New York 10017, in writing not later than December 22, 2025.

Stockholders intending to present a proposal at our 2026 Annual Meeting, but not to include the proposal in our proxy statement, or to nominate a person for election as a director, must comply with the requirements set forth in our Bylaws. Our Bylaws require, among other things, that our Secretary receive written notice from the stockholder of record of their intent to present such proposal or nomination not earlier than the 120th day and not later than the 90th day prior to the first anniversary of the preceding year's annual meeting of stockholders. Therefore, we must receive notice of such a proposal or nomination for the 2026 Annual Meeting no earlier than February 3, 2026 and no later than March 5, 2026. The notice must contain the information required by our Bylaws. In the event that the date of the 2026 Annual Meeting is more than 30 days before or more than 60 days after June 3, 2026, to be timely, such notice must be so delivered, or mailed and received, not later than the 90th day prior to the 2026 Annual Meeting or, if later, the 10th day following the day on which public disclosure of the date of such meeting is first made by us. SEC rules permit management to vote proxies in its discretion in certain cases if the stockholder does not comply with this deadline and, in certain other cases notwithstanding the stockholder's compliance with this deadline.

In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the company's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act.

We reserve the right to reject, rule out of order or take other appropriate action with respect to any proposal that does not comply with these or other applicable requirements.

In connection with our solicitation of proxies for our 2026 Annual Meeting of stockholders, we intend to file a proxy statement and WHITE proxy card with the SEC. Stockholders may obtain our proxy statement (and any amendments and supplements thereto) and other documents as and when filed with the SEC without charge from the SEC's website at: www.sec.gov.

**<u>[**Table of Contents**](#i1595b230957b454db5a3ff6369fa417d_16)</u>**

**HOUSEHOLDING** 

SEC rules permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and notices with respect to two or more stockholders sharing the same address by delivering a single proxy statement or a single notice addressed to those stockholders. This process, which is commonly referred to as "householding," provides cost savings for companies and helps the environment by conserving natural resources. We and some brokers household proxy materials, delivering a single proxy statement or notice to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement or notice, or if your household is receiving multiple copies of these documents and you wish to request that future deliveries be limited to a single copy, please notify your broker. You can also request prompt delivery of a copy of this Proxy Statement and the Annual Report by contacting the Broadridge Financial Solutions, Inc. at (866) 540-7095 or in writing at Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.
