As Representative of the several Underwriters

named in Schedule I hereto

Ladies and Gentlemen:

Cipher Mining Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule I hereto (the “Underwriters,” and to the extent there is only a single underwriter, the term “Underwriters” shall be deemed to refer to the single Underwriter, mutatis mutandis), for whom you are acting as representative (the “Representative”), $150.0 million principal amount of its 1.75% Convertible Senior Notes due 2030 (the “Firm Securities”) to be issued pursuant to the provisions of an Indenture to be dated as of the Closing Date (as defined in Section 4) (the “Base Indenture”) between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), as supplemented by that certain First Supplemental Indenture to such Base Indenture between the Company and the Trustee (the “First Supplemental Indenture” and together with the Base Indenture, the “Indenture”). The Company also proposes to issue and sell to the Underwriters not more than an additional $22.5 million principal amount of its 1.75% Convertible Senior Notes due 2030 (the “Additional Securities”), solely to cover over-allotments, if and to the extent that the Representative shall have determined, on behalf of the Underwriters, to exercise the right to purchase such Additional Securities granted to the Underwriters in Section 2 hereof. The Firm Securities and the Additional Securities are hereinafter collectively referred to as the “Securities.” Shares of the Company’s common stock, $0.001 par value per share, are hereinafter referred to as the “common stock.” The Securities will be convertible into cash, shares of common stock (the “Underlying Securities”), or a combination of cash and Underlying Securities, at the Company’s election.

Concurrently with the issuance and offering of the Securities, shares of the Company’s common stock are being offered and sold (the “Concurrent Delta Offering”) by the underwriter of the Concurrent Delta Offering (the “Delta Underwriter”), acting on behalf of itself and/or its respective affiliates, to facilitate hedging transactions by certain investors subscribing for the Securities (the “Convertible Arbitrage Investors”). It is expected that the common stock sold by the Delta Underwriter in the Concurrent Delta Offering will be borrowed from third parties, and will be: (x) purchased by the Delta Underwriter from certain Convertible Arbitrage Investors who have sold them short to such Delta Underwriter in connection with the offering of the Securities, and/or (y) sold short by the Delta Underwriter to facilitate its

concurrent privately negotiated transactions with certain Convertible Arbitrage Investors seeking a short exposure to the Company’s common stock through a derivative, in an equal notional amount. The Company and the Delta Underwriter are entering into an underwriting agreement dated hereof with respect to the Concurrent Delta Offering (the “Delta Underwriting Agreement”). For the avoidance of doubt, there is no new issuance of common stock in the Concurrent Delta Offering.

On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to sell to the Underwriters the Additional Securities, and the Underwriters shall have the right to purchase, severally and not jointly, the Additional Securities solely to cover over-allotments at the Purchase Price.

(v) (i) The Company represents and agrees that, other than the final term sheet prepared and filed pursuant to Section 6(a) hereof, and any electronic road show furnished to the Representative before first use, without the prior consent of the Representative, it has not made and will not make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act; (ii) each Underwriter represents and agrees that, without the prior consent of the Company and the Representative, other than one or more term sheets relating to the Securities containing customary

(y) The Company also agrees that, without the prior written consent of the Representative on behalf of the Underwriters, it will not, and will not publicly disclose an intention to, during the period commencing on the date hereof and ending 45 days after the date of the Prospectus (the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock (the “Lock-Up Securities”), (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Lock-Up Securities, or (3) file any registration statement with the Commission relating to the offering of any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of common stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (A) the issuance and

sale of the Securities under this Agreement and the issuance of the Conversion Securities upon conversion of such Securities, (B) the issuance by the Company of any Lock-Up Securities upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof as described in each of the Pricing Prospectus and the Prospectus, (C) the registration of the common stock offered in the Concurrent Delta Offering under the Securities Act, (D) facilitating the establishment of a trading plan on behalf of a shareholder, officer or director of the Company pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Lock-Up Securities, provided that (i) such plan does not provide for the transfer of Lock-Up Securities during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of common stock may be made under such plan during the Restricted Period, (E) the filing of a registration statement on Form S-8 relating to, and the issuance and sale of Lock-Up Securities pursuant to, the terms of a plan described in the Pricing Prospectus and the Prospectus, and (F) the issuance and sale of shares of Common Stock pursuant to the amended and restated at-the-market sales agreement, dated September 3, 2024, by and between the Company and Cantor ▇▇▇▇▇▇▇▇▇▇ & Co., Canaccord Genuity LLC, Needham & Company, LLC, Compass Point Research & Trading, LLC, Keefe, ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇, Inc., Virtu Americas LLC, and BTIG, LLC as sales agents relating to the Company’s at-the-market sales program as described in the Prospectus, following the earlier to occur of (i) the Underwriters’ exercise in full of their option to purchase the Additional Securities as set forth in Section 2 hereof and (ii) the Option Expiration Date.

7. Indemnity and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, any Issuer Free Writing Prospectus prepared by or on behalf of, used by, or referred to by the Company, any General Solicitation made by the Company, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”), the Prospectus or any amendment or supplement thereto, or arise out of, or are based upon, any omission or alleged omission to state therein a material fact necessary to make the statements therein in light of the circumstances under which they were made not misleading, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any such untrue statement or omission or alleged untrue

statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by or on behalf of such Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by the Underwriters through the Representative consists of the information described as such in paragraph (b) below. The Company agrees and confirms that references to “affiliates” of the Representative that appear in this Agreement shall be understood to include Mitsubishi UFJ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Securities Co., Ltd.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by or on behalf of such Underwriter through the Representative expressly for use in the Preliminary Prospectus, the Pricing Prospectus, any Issuer Free Writing Prospectus set forth in Schedule II hereto, road show, General Solicitation set forth in Schedule II hereto, the Prospectus or any amendment or supplement thereto, it being understood and agreed that the only information furnished by or on behalf of any such Underwriter consists of the following information in the Preliminary Prospectus, the Pricing Prospectus and the Prospectus furnished on behalf of each Underwriter is the information contained in the first and second sentence of the ninth paragraph under the caption “Underwriting”.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 7(a) or 7(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are

incurred. Such firm shall be designated in writing by the Representative, in the case of parties indemnified pursuant to Section 7(a), and by the Company, in the case of parties indemnified pursuant to Section 7(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) To the extent the indemnification provided for in Section 7(a) or 7(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 7(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 7(d)(i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the total discounts and commissions received by the Underwriters bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and of the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the respective principal amount of Securities they have purchased hereunder, and not joint.

(e) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 7(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities resold by it in the initial placement of such Securities were offered to investors exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 7 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

8. Termination. The Underwriters may terminate this Agreement by notice given by the Representative to the Company, if after the execution and delivery of this Agreement and prior to or on the Closing Date, or, in the case of the Additional Securities, prior to any Option Closing Date, as the case may be, (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, either of the New York Stock Exchange or Nasdaq, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the Representative’s judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Representative’s judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Pricing Prospectus or the Prospectus.

9. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the principal amount of Firm Securities set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Firm Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representative may specify, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 9 by an amount in excess of one-ninth of such principal amount of Securities without the written consent of such Underwriter. If, on the Closing Date any Underwriter or Underwriters shall fail or refuse to purchase Firm Securities which it has or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Firm Securities to be purchased on such date, and arrangements satisfactory to the Representative and the Company for the purchase of such Firm Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or of the Company. In any such case either the Representative or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Pricing Prospectus, the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Securities and the aggregate principal amount of Additional Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Additional Securities to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (a) terminate their obligation hereunder to purchase the Additional Securities to be sold on such Option Closing Date or (b) purchase not less than the principal amount of Additional Securities that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, other than solely because of the termination of this Agreement pursuant to Section 9 or the occurrence of any event specified in clause (i), (iii), (iv) or (v) of Section 8 above, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all accountable out-of-pocket expenses (including the fees and disbursements of their counsel) actually incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

10. Entire Agreement.

(a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Securities, represents the entire agreement between the Company and the Underwriters with respect to the preparation of the Preliminary Prospectus, the Pricing Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Securities.

(b) The Company acknowledges that in connection with the offering of the Securities: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement, any contemporaneous written agreements and prior written agreements (to the extent not superseded by this Agreement) if any, (iii) the Underwriters may have interests that differ from those of the Company and (iv) none of the activities of the Underwriters in connection with the transactions contemplated herein constitutes a recommendation, investment advice, or solicitation of any action by the Underwriters with respect to any entity or natural person. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

11. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

referred to below

c/o Morgan ▇▇▇▇▇▇▇ & Co. LLC

▇▇▇▇ ▇▇▇▇▇▇▇▇

New York, New York 10036

Ladies and Gentlemen:

As an inducement to the Underwriters to execute the Underwriting Agreement (the “Underwriting Agreement”), pursuant to which an offering will be made of Convertible Senior Notes due 2030 (the “Securities”), of Cipher Mining Inc., and any successor (by merger or otherwise) thereto, (the “Company”), the undersigned hereby agrees that during the period specified in the following paragraph (the “Restricted Period”), the undersigned will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of common stock, $0.001 par value (the “common stock”) beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) or securities convertible into or exchangeable or exercisable for any common stock, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of the common stock, whether any such aforementioned transaction is to be settled by delivery of common stock or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC (the “Representative”). In addition, the undersigned agrees that, without the prior written consent of the Representative, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any common stock or any security convertible into or exercisable or exchangeable for the common stock.

The Restricted Period will commence on the date of this Lock-Up Agreement and continue and include the date 45 days after the date of the final prospectus used to sell the Securities (the “Offering Date”) pursuant to the Underwriting Agreement.

A-1

Any common stock received upon exercise of options or other common stock of the Company granted to the undersigned and any common stock acquired by the undersigned in the open market will also be subject to this Lock-Up Agreement. Additionally, the restrictions in this Lock-Up Agreement shall not apply to (a) any transactions relating to common stock acquired in the open market after the closing of the offering, provided that with respect to any sale or other disposition of such common stock, no filing under the Exchange Act (other than on Form 5) or other public announcement shall be required or shall be voluntarily made by any party in connection with subsequent sales of such common stock acquired in such open market transactions during the Restricted Period, (b) any exercise of options or vesting or exercise of any other equity-based award, in each case, outstanding on the Offering Date, and in each case under the Company’s equity incentive plan or any other plan or agreement described in the prospectus included in the Registration Statement, provided that any common stock received upon such exercise or vesting will also be subject to this Lock-Up Agreement, (c) transfers as a bona fide gift or gifts, (d) transfers to a family member, trust, family limited partnership or family limited liability company for the direct or indirect benefit of the undersigned or his or her family members, (e) transfers by testate or intestate succession, provided that in each transfer pursuant to clauses (c) through (e) the transferee agrees to be bound in writing by the terms of this Lock-Up Agreement prior to such transfer, such transfer shall not involve a disposition for value and no filing or public announcement by any party (donor, donee, transferor or transferee) under the Exchange Act or otherwise shall be required or shall be voluntarily made in connection with such transfer (other than a filing on a Form 5), or (f) the establishment of any written contract, instruction or plan that satisfies all of the requirements of Rule 10b5-1 (a “Rule 10b5-1 Plan”) under the Exchange Act; provided, however, that no sales of common stock or securities convertible into, or exchangeable or exercisable for, common stock, shall be made pursuant to a Rule 10b5-1 Plan prior to the expiration of the Restricted Period (as the same may be extended pursuant to the provisions hereof); and provided further, that no party is required to publicly announce, file, or report the establishment of such Rule 10b5-1 Plan in any public report, announcement, or filing with the Commission under the Exchange Act during the Restricted Period and does not otherwise voluntarily effect any such public report, announcement, or filing regarding such Rule 10b5-1 Plan.

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of shares of common stock if such transfer would constitute a violation or breach of this Lock-Up Agreement.

If the undersigned is an officer or director of the Company, the Representative agrees that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of common stock, the Representative will notify the Company of the impending release or waiver. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this Lock-Up Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

A-2

The undersigned acknowledges and agrees that the Underwriters have not provided any recommendation or investment advice nor have the Underwriters solicited any action from the undersigned with respect to the offering of the Securities and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate. The undersigned further acknowledges and agrees that, although the Underwriters may provide certain Regulation Best Interest and Form CRS disclosures or other related documentation to you in connection with the offering, the Underwriters are not making a recommendation to you to participate in the offering or sell any Securities at the price determined in the offering, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

This Lock-Up Agreement shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned.

Whether or not the offering actually occurs depends on a number of factors, including market conditions. Any offering will only be made pursuant to a Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters. It is understood that if the Underwriting Agreement is executed yet terminates (other than the provisions thereof that survive termination) prior to payment for and delivery of the Securities, the undersigned shall be released from all obligations under this Lock-Up Agreement.

This agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

This Agreement may be executed and delivered by facsimile, by email in portable document format (.pdf), or any electronic signature complying with the U.S. federal ESIGN Act of 2000 (e.g., DocuSign) and delivery of the signature page by such method will be deemed to have the same effect as if the original signature had been delivered to the other parties.

Filed Pursuant to Rule 433

Registration Statement No. 333-281908

Relating to the

Preliminary Prospectus Supplement

Dated May 20, 2025

(To Prospectus Dated September 3, 2024)

PRICING TERM SHEET

May 20, 2025

Cipher Mining Inc.

Offering of

$150,000,000 Aggregate Principal Amount of

1.75% Convertible Senior Notes due 2030

The information in this pricing term sheet supplements Cipher Mining Inc.’s preliminary prospectus supplement, dated May 20, 2025 (the “Preliminary Prospectus Supplement”), and supersedes the information in the Preliminary Prospectus Supplement to the extent inconsistent with the information in the Preliminary Prospectus Supplement. Terms used, but not defined, in this pricing term sheet have the respective meanings set forth in the Preliminary Prospectus Supplement. As used in this pricing term sheet, “we,” “our” and “us” refer to Cipher Mining Inc. and not to its subsidiaries.


Issuer		Cipher Mining Inc.

Ticker / Exchange for Common Stock		CIFR / Nasdaq Global Select Market (“Nasdaq”).

Notes		1.75% convertible senior notes due 2030 (the “Notes”).

Principal Amount		$150,000,000 (or, if the underwriters fully exercise their option to purchase additional Notes, $172,500,000) aggregate principal amount of Notes.

Public Offering Price		100% of the principal amount of the Notes, plus accrued interest, if any, from the Settlement Date.

Underwriting Discount		2.75%.

Maturity		May 15, 2030, unless earlier repurchased, redeemed or converted.

Stated Interest Rate		1.75% per annum.


Interest Payment Dates		May 15 and November 15 of each year, beginning on November 15, 2025.

Record Dates		May 1 and November 1.

Last Reported Sale Price per Share of Common Stock on Nasdaq on May 20, 2025		$3.78.

Public Offering Price per Share of Common Stock in the Concurrent Delta Offering (as defined below)		Initially, $3.42 per share of common stock.

Conversion Premium		Approximately 30% above the Public Offering Price per Share of common stock in the Concurrent Delta Offering (as defined below).

Initial Conversion Price		Approximately $4.45 per share of our common stock.

Initial Conversion Rate		224.9213 shares of our common stock per $1,000 principal amount of Notes.

Optional Redemption		The Notes will be redeemable, in whole or in part (subject to certain limitations described below), at our option at any time, and from time to time, on or after May 22, 2028 and on or before the 30th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of our common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date we send the related redemption notice; and (2) the trading day immediately before the date we send such notice. However, we may not redeem less than all of the outstanding Notes unless at least $50.0 million aggregate principal amount of Notes are outstanding and not called for redemption as of the time we send the related redemption notice. In addition, calling any Note for redemption will constitute a make-whole fundamental change with respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for redemption. See “Description of Notes—Optional Redemption” in the Preliminary Prospectus Supplement.


Repurchase at the Option of the Noteholders on May 15, 2028		Noteholders may require us to repurchase their Notes on May 15, 2028, at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date. See “Description of Notes—Purchase of Notes by Us at the Option of the Noteholders” in the Preliminary Prospectus Supplement.

Use of Proceeds		We estimate that the net proceeds to us from this offering, before offering expenses, will be approximately $145.9 million (or approximately $167.8 million if the underwriters fully exercise their option to purchase additional Notes), after deducting the underwriting discounts and commissions. We expect to use the net proceeds to complete Phase 1 of the Black Pearl data center project (“Phase 1”), including: (i) purchasing at a discount the remaining balance of mining rigs required for Phase 1; (ii) paying expected tariffs and shipping costs for the mining rigs to be used for Phase 1; and (iii) paying other infrastructure-related capital expenditures in connection with Phase 1, and for general corporate purposes. See “Use of Proceeds” in the Preliminary Prospectus Supplement.

Concurrent Delta Offering		Concurrently with this offering, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC, acting on behalf of itself and/or its affiliates (in such capacity, the “delta offering underwriter”), is offering, in a separate, underwritten public offering pursuant to a prospectus supplement that we have filed with the Securities and Exchange Commission, 17,540,000 shares of our common stock initially at a public offering price of $3.42 per share, to facilitate hedging transactions by certain investors (the “convertible arbitrage investors”) subscribing for the Notes. The number of shares of our common stock subject to the Concurrent Delta Offering is expected to generally correspond to the initial short positions of convertible arbitrage investors being established to hedge their market risk with respect to the Notes they acquire. We have been advised that the shares sold by the delta offering underwriter in the Concurrent Delta Offering will be borrowed from third parties, and will be: (x) purchased by the delta offering underwriter from certain convertible arbitrage investors who have sold them short to


		such delta offering underwriter in connection with the offering of the Notes, and/or (y) sold short by the delta offering underwriter to facilitate its concurrent privately negotiated transactions with certain convertible arbitrage investors seeking a short exposure to our common stock through a derivative, in an equal notional amount. No new shares of our common stock will be issued for the Concurrent Delta Offering. We will not receive any proceeds from the Concurrent Delta Offering.

Trade Date		May 21, 2025.

Settlement Date		May 22, 2025; provided that the completion of this offering is contingent upon the completion of the Concurrent Delta Offering, and the completion of the Concurrent Delta Offering is contingent upon the completion of this offering.

Increase to Conversion Rate in Connection with a Make-Whole Fundamental Change		If a make-whole fundamental change occurs with respect to any Note and the conversion date for the conversion of such Note occurs during the related make-whole fundamental change conversion period, then, subject to the provisions described in the Preliminary Prospectus Supplement under the caption “Description of Notes—Conversion Rights—Increase in Conversion Rate in Connection with a Make-Whole Fundamental Change,” the conversion rate applicable to such conversion will be increased by a number of shares set forth in the table below corresponding (after interpolation, as described below) to the make-whole fundamental change effective date and the stock price of such make-whole fundamental change:


	Stock Price
Make-Whole Fundamental Change Effective Date	$3.42		$4.00		$4.45		$5.50		$5.78		$7.50		$10.00		$15.00		$30.00		$50.00

If such make-whole fundamental change effective date or stock price is not set forth in the table above, then:

•

if such stock price is between two stock prices in the table above or the make-whole fundamental change effective date is between two dates in the table above, then the number of additional shares will be determined by straight-line interpolation between the numbers of additional shares set forth for the higher and lower stock prices in the table above or the earlier and later dates in the table above, based on a 365- or 366-day year, as applicable; and

•

if the stock price is greater than $50.00 (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above are adjusted, as described in the Preliminary Prospectus Supplement under the caption “Description of Notes—Conversion Rights—Increase in Conversion Rate in Connection with a Make-Whole Fundamental Change—Adjustment of Stock Prices and Number of Additional Shares”), or less than $3.42 (subject to adjustment in the same manner), per share, then no additional shares will be added to the conversion rate.

Notwithstanding anything to the contrary, in no event will the conversion rate be increased to an amount that exceeds 292.3976 shares of our common stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the conversion rate is required to be adjusted pursuant to the provisions described in the Preliminary Prospectus Supplement under the caption “Description of Notes—Conversion Rights—Conversion Rate Adjustments—Generally.”
