Anyone owning shares of Common Stock or Series A Preferred Stock at the close of business on August 25, 2025, the Record Date for this Special Meeting, is entitled to attend and to vote on all items properly presented at the Special Meeting.

Stockholder of Record: Shares Registered in Your Name. If, at the close of business on the Record Date, your shares were registered directly in your name with our transfer agent, EQ Shareowner Services (“EQ”), then you are a stockholder of record. As a stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card, to vote electronically at the Special Meeting, or by Internet or by telephone, or, if you received paper copies of the proxy materials by mail, to vote by mail by following the instructions on the proxy card or voting instruction card.

Beneficial Owner of Shares Held in “Street Name”: Shares Registered in the Name of a Broker, Bank or Other Nominee. If, at the close of business on the Record Date, your shares were held not in your name, but rather in

Table of Contents

an account at a brokerage firm, bank or other nominee, then you are the beneficial owner of shares held in “street name” and the Notice is being forwarded to you by that nominee. The nominee holding your account is considered the stockholder of record for purposes of voting at the Special Meeting. As a beneficial owner, you have the right to direct your broker, bank or other nominee regarding how to vote the shares in your account by following the voting instructions your broker, bank or other nominee provides. You are also invited to attend the Special Meeting. However, since you are not the stockholder of record, you may not vote your shares electronically at the Special Meeting unless you obtain a legal proxy from your broker, bank or other nominee. Please see “How do I vote and what are the voting deadlines?” below regarding voting procedures for beneficial owners.

How do I vote and what are the voting deadlines?

Stockholder of Record: Shares Registered in Your Name. If you are a stockholder of record, you may vote in any one of the following ways:

You may vote at the Special Meeting. If you or your proxy wish to vote at the Special Meeting, you or your proxy will need to attend the Special Meeting by visiting www.proxypush.com/WULF. To be admitted to the virtual meeting, eligible persons must first register at anytime before the Special Meeting by visiting register.proxypush.com/WULF on their smartphone, tablet or computer. You will then be required to enter your 16-digit control number included in your voting instruction form or proxy card. If you encounter any difficulty accessing the Special Meeting or during the Special Meeting, please call the technical support number posted on the Special Meeting website. The technical support number will be available at least 15 minutes before the start of the meeting. If you vote in advance online, by phone or by mailing in a proxy card, you may still attend the Special Meeting and vote during the meeting, but, in that case, only the votes you enter during the meeting will count.

Even if you plan to attend the Special Meeting, we recommend that you also vote either by telephone, by Internet, or by mail so that your vote will be counted if you ultimately decide not, or are unable, to attend.

•You may vote by mail. To vote by mail, complete, sign and date the proxy card that accompanies this Proxy Statement and return it promptly in the postage-prepaid envelope provided (if you received printed proxy materials). Your completed, signed and dated proxy card must be received by 11:59 p.m. Eastern Time on September 29, 2025.

•You may vote by telephone. To vote over the telephone, call toll-free 1-866-883-3382 from any touch-tone telephone and follow the instructions. Have your proxy card available when you call. You will be asked to provide the control number from your proxy card. Telephone voting is available 24 hours a day, 7 days a week, and will be accessible until the polls are closed at the end of the Special Meeting.

•You may vote via the Internet. To vote via the Internet, go to www.proxypush.com/WULF to complete an electronic proxy card (have your proxy card in hand when you visit the website). You will be asked to provide the control number from your proxy card. Internet voting is available 24 hours a day, 7 days a week, and will be accessible until the polls are closed at the end of the Special Meeting.

Beneficial Owner of Shares Held in “Street Name”: Shares Registered in the Name of a Broker, Bank or Other Nominee. If you are a beneficial owner of shares held of record by a broker, bank or other nominee, you will receive voting instructions from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank or other nominee in order to instruct your broker, bank or other nominee on how to vote your shares. Beneficial owners of shares should generally be able to vote by returning the voting instruction card received from their broker, bank or other nominee to such nominee, or by telephone or via the Internet. However, the availability of telephone or Internet voting will depend on the voting process of your broker, bank or other nominee. As discussed above, if you are a beneficial owner, you may not vote your shares electronically at the Special Meeting unless you obtain a legal proxy from your broker, bank or other nominee. We therefore urge you to vote in advance of the Special Meeting using the voting instructions provided by your broker, bank or other nominee.

How can I participate during the Special Meeting?

We have designed the virtual Special Meeting to provide substantially the same opportunities to participate as stockholders would have at an in-person meeting. Our virtual Special Meeting will be conducted on the Internet via live webcast. Stockholders will be able to attend and participate online and submit questions in advance and during the Special Meeting by visiting www.proxypush.com/WULF.

The virtual Special Meeting format allows stockholders to communicate with us during the Special Meeting so they can ask questions of our management and Board, as appropriate. If you wish to submit a question or questions in advance of the Special Meeting, you may do so at www.proxypush.com/WULF on an ongoing basis. If you wish to submit a question during the Special Meeting, you may do so by logging into the virtual meeting platform at www.proxypush.com/WULF, clicking the Q&A button on your screen and typing your question into the provided text field.

We reserve the right to exclude questions regarding topics that are not pertinent to meeting matters or Company business or are inappropriate. If we receive substantially similar questions, we may group such questions together and provide a single response to avoid repetition. Any questions that are appropriate and pertinent to the Special Meeting will be answered in the live Question and Answer session during the Special Meeting, subject to time constraints. Additional information regarding the ability of stockholders to ask questions during the Special Meeting, related rules of conduct, and other materials for the Special Meeting will be available during the Special Meeting at www.proxypush.com/WULF.

Can I change my vote or revoke my proxy?

Stockholder of Record: Shares Registered in Your Name. If you are a stockholder of record, you can change your vote or revoke your proxy by:

•Providing another proxy, or using any of the available methods for voting, with a later date;

•Notifying the Company’s secretary in writing before the Special Meeting that you wish to revoke your proxy; or

•Voting at the Special Meeting.

Beneficial Owner of Shares Held in “Street Name”: Shares Registered in the Name of a Broker, Bank or Other Nominee. If you are the beneficial owner of your shares, you must contact the broker, bank or other nominee holding your shares and follow their instructions to change your vote or revoke your proxy.

Who is asking for my vote?

The Company has hired D.F. King & Co., Inc. to assist in the solicitation of proxies for an estimated fee of $12,500, plus out-of-pocket expenses. The solicitation of proxies is made on behalf of our Board of Directors. The Company will bear the cost of soliciting proxies and will reimburse brokerage firms and others for expenses involved in forwarding proxy materials to beneficial owners or soliciting their execution. In addition to solicitations by mail, the Company, through its directors and employees, may solicit proxies in person, by telephone or by electronic means. Such directors and employees will not receive any special remuneration for these efforts.

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of our Board of Directors. The persons named in the proxy have been designated as proxies for the Special Meeting by our Board of Directors. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the Special Meeting in accordance with the instructions of the stockholder on such proxy. If no specific instructions are given, however, the shares will be voted

Table of Contents

in accordance with the recommendations of our Board of Directors on the proposal as described below, the shares will be voted in accordance with the proxies’ judgment.

What are my voting rights?

Each share of Common Stock is entitled to one vote on each matter properly presented at the Special Meeting. At the close of business on Monday, August 25, 2025, there were 407,944,157 shares of Common Stock outstanding. A list of all record stockholders as of the Record Date will be available during ordinary business hours at the Company’s principal place of business located at 9 Federal Street, Easton, MD 21601, from September 18, 2025, at least 10 days before the Special Meeting and will also be available during the Special Meeting.

What is the quorum requirement for the Special Meeting?

A quorum is the minimum number of shares required to be present or represented at the Special Meeting for the meeting to be properly held. The presence, represented in person or by proxy, of the holders of a majority of the voting power of our outstanding Common Stock entitled to vote at the Special Meeting will constitute a quorum to transact business at the Special Meeting. Abstentions are counted as present and entitled to vote for purposes of determining a quorum. If there is no quorum, the chair of the meeting may adjourn the meeting to another time or place.

What are broker non-votes?

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker, bank or other nominee, as applicable, holding the shares as to how to vote on matters deemed “non-routine.” The beneficial owner of shares held in “street name” is entitled to give voting instructions to the broker, bank or other nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker, bank or other nominee can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters.

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 are the effects of abstentions?

An abstention represents a stockholder’s affirmative choice to decline to vote on a proposal. If a stockholder indicates on its proxy card that it wishes to abstain from voting its shares, or if a broker, bank or other nominee causes abstentions to be recorded for shares, these shares will be considered present and entitled to vote at the Special Meeting. As a result, abstentions will be counted for purposes of determining the presence or absence of a quorum and will also count as votes “AGAINST” a proposal in cases such as the Charter Amendment Proposal where approval of the proposal requires the affirmative vote of a majority of the voting power of the total outstanding shares entitled to vote, regardless of whether such shares are present in person or represented by proxy at the Special Meeting.

What is the voting requirement to approve the Charter Amendment Proposal?

Approval of the Charter Amendment Proposal. The approval of the Charter Amendment Proposal requires the affirmative vote of a majority of the voting power of the outstanding shares of our capital stock (Common Stock and Series A Preferred Stock, voting together as a single class), regardless of whether such shares are present in person or represented by proxy at the Special Meeting. You may vote “FOR,” “AGAINST,” or “ABSTAIN” on this proposal. Abstentions will count towards the quorum requirement for the Special Meeting and will have the same effect as a vote “AGAINST” the proposal.

Table of Contents

What if I do not vote, do not specify how my shares are to be voted or fail to provide timely directions to my broker, bank or other nominee?

Stockholder of Record. If you are a stockholder of record and do not vote through the Internet, by completing your proxy card, by telephone or virtually at the Special Meeting, your shares will not be voted. If you are a stockholder of record and you submit a proxy, but you do not provide voting instructions, your shares will be voted “FOR” the Charter Amendment Proposal.

Street Name Stockholders. Brokers, banks, and other nominees holding shares of Common Stock in street name for customers are generally required to vote such shares in the manner directed by their customers.

Who will count the votes?

A representative of EQ will tabulate the votes and act as inspector of elections.

May I vote confidentially?

Yes. Our policy is to keep your vote confidential, except as otherwise legally required, to allow for the tabulation and certification of votes and to facilitate proxy solicitation.

Where can I find the voting results from the Special Meeting?

We will announce preliminary voting results at the Special Meeting and will publish final results in a Current Report on Form 8-K that we will file with the Securities and Exchange Commission (the “SEC”) within four business days after the date the Special Meeting concludes.

How can I obtain information about the Company?

A copy of our annual report on Form 10-K for the fiscal year ended December 31, 2024 (our “Annual Report”) is available on our website at www.investors.terawulf.com. Stockholders may also obtain a free copy of our Annual Report, including the financial statements and the financial statement schedules, by visiting our website or by sending a request in writing to Attention: Office of the General Counsel, TeraWulf Inc., 9 Federal Street, Easton, MD 21601.

How can I contact the Company’s transfer agent?

You may contact our transfer agent, EQ Shareowner Services, by telephone at 651-450-4064, or by e-mail at stocktransfer@equiniti.com.

I share an address with another stockholder, and we received only one copy of the Proxy Statement. How may I obtain an additional copy of the Proxy Statement?

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Special Meeting materials with respect to two or more stockholders sharing the same address by delivering a single set of Special Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies. For this meeting, a number of brokers with account holders who are our stockholders will be “householding” the Company’s proxy materials. A single set of Special Meeting materials will be delivered 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” communications 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 set of Special Meeting materials, please notify your broker or us. You may contact us at our principal executive offices as follows:

Stockholders who currently receive multiple copies of the Special Meeting materials at their addresses and would like to request “householding” of their communications should contact their brokers.

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 Amended and Restated Certificate of Incorporation, which is attached to this Proxy Statement as Appendix A (the “Charter Amendment”), to increase the number of shares of our Common Stock authorized for issuance from 600,000,000 to 950,000,000. 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:

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

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

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

•Other general corporate purposes approved by the Board.

Recent Developments

In August 2025, the Company executed a series of strategic transactions, each of which included the issuance of shares of Common Stock and/or warrants exercisable for shares of Common Stock. These transactions included: (i) issuing warrants to Google LLC (“Google”) in connection with ten-year data center lease agreements with Fluidstack USA I Inc., each supported by a financial backstop from Google; (ii) entering into a long-term ground lease for the Cayuga site in Lansing, New York, providing up to 400 megawatts of additional data center capacity; and (iii) issuing 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 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.

This description of the effect of the Charter Amendment Proposal is a summary and is qualified by the full text of the Charter Amendment, which is attached to this Proxy Statement as Appendix A and incorporated herein by reference.

Vote Required and Recommendation of the Board

Approval of the Charter Amendment Proposal requires FOR votes from the holders of at least a majority of the total outstanding shares entitled to vote, regardless of whether such shares are present in person or represented by proxy at the Special Meeting. You may vote “FOR” or “AGAINST” this proposal, or you may indicate that you wish to “ABSTAIN” from voting on this proposal. Abstentions will be counted for purposes of determining the presence or absence of a quorum and will have the same effect as a vote “AGAINST” this proposal. Because the Charter Amendment Proposal is a “routine” proposal, we do not expect broker non-votes.

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. The Charter Amendment will become effective at the time of the filing.

Table of Contents

Notwithstanding the foregoing, at any time prior to the effectiveness of the filing of the Charter Amendment with the Secretary of State of the State of Delaware, our Board reserves the right to abandon the Charter Amendment and not to file it, 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 Amended and Restated Certificate of Incorporation will remain in place and our number of authorized shares will remain unchanged.

The Board unanimously recommends that stockholders vote “FOR” the approval of the Charter Amendment.
