The Subscriber shall also have the option to purchase additional Ordinary Shares, at the Purchase Price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.2 Drawdowns/Tranches.**

Each Drawdown Notice shall be delivered not less than ten (10) Trading Days prior to the proposed Tranche Closing Date.

Minimum: $500,000. **Maximum: $1,000,000.00** per Tranche unless otherwise agreed by Subscriber in writing.

**3. Securities; Depositary Issuance**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.1 Issuance.**

On each Tranche Closing Date (subject to Section 6), the Company shall allot and issue to the Depositary, for deposit under the Company's ADR program, such number of Ordinary Shares as is determined under Section 4 (the "Tranche Shares"), and shall instruct the Depositary to issue corresponding Restricted ADSs to the Subscriber (or its designated account).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.2 Register.**

The Company shall ensure that its register of members is updated to reflect the issuance of the Tranche Shares following each Tranche.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.3 Depositary Procedures.**

The parties shall cooperate with the Depositary and Computershare to effect each issuance, including completion of any depositary forms, delivery of instructions, and application of restriction/legend coding consistent with a private placement.

Within forty-five (45) days (or such later date as the parties may agree in writing) following the first Tranche Closing Date, the Company shall file a resale registration statement covering the ADSs issued under this Agreement and shall use commercially reasonable efforts to cause such registration statement to become effective as soon as practicable.

**4. Purchase Price; Share Calculation**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.1 Pricing Methodology.**

The purchase price per Ordinary Share for a Tranche (the "Purchase Price") shall equal 100% of the average Nasdaq Official Closing Price over the five (5) Trading Day lookback period ending on the Trading Day immediately preceding the Drawdown Notice date (or for the week of March 16-20, 2026 for Drawdown Notice No. 1) and converted into a per-Ordinary Share price using the ADS-to-Ordinary Share ratio then in effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.2 Tranche Shares.**

The number of Tranche Shares to be issued for a Tranche shall equal the Tranche Amount divided by the Purchase Price (rounded down to the nearest whole share).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.3 Nasdaq Minimum Price.**

Notwithstanding anything to the contrary in this Agreement, the Purchase Price for any Tranche shall not be less than the "Minimum Price" (as defined in Nasdaq Listing Rule 5635(d)) as of the applicable Tranche Closing Date. The parties acknowledge and agree that the pricing methodology set forth herein shall be interpreted and applied in a manner consistent with compliance with Nasdaq Listing Rule 5635(d).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.4 Nasdaq 20% Limitation.**

Notwithstanding anything to the contrary in this Agreement, the aggregate number of Ordinary Shares (or ADS equivalents) issued pursuant to this Agreement shall not exceed 19.99% of the outstanding Ordinary Shares (on an as-converted ADS-equivalent basis, if applicable) or voting power of the Company as of the Effective Date (the "Exchange Cap"), unless shareholder approval is obtained in accordance with applicable Nasdaq rules. If, at any time, issuance of a Tranche would cause the Exchange Cap to be exceeded, such Tranche shall be automatically reduced to the maximum amount permitted without shareholder approval.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.5 Floor Price.**

Notwithstanding anything to the contrary contained in this Agreement, Subscriber shall have no obligation to fund Tranches to purchase securities at a price below the Floor Price.

**5. U.S. Securities Law Matters; Transfer Restrictions**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.1 Private Placement.**

The Subscriber acknowledges that the Tranche Shares and the Restricted ADSs are being offered and sold in a transaction exempt from registration under the U.S. Securities Act of 1933, as amended (the "Securities Act"), and have not been registered under the Securities Act or any state securities laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.2 Restricted Securities.**

The Subscriber agrees that the Tranche Shares and Restricted ADSs will be issued as "restricted securities" and may not be offered, sold, pledged or otherwise transferred absent registration or an available exemption (including, if applicable, Rule 144). Appropriate legends/restrictions will apply.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.3 MNPI / Confidentiality.**

If the Company provides material non-public information to the Subscriber, the Subscriber agrees to keep such information confidential and to comply with applicable insider trading restrictions until such information is publicly disclosed or otherwise cleansed. Subscriber shall not be required to consummate any Tranche while in possession of material non-public information provided by the Company unless such information has been publicly disclosed.

**6. Conditions to Each Tranche**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.1 Tranche Conditions.**

Each Tranche is subject to (a) the Company having sufficient shareholder authorities and/or valid disapplication of pre-emption rights to allot and issue the Tranche Shares; (b) no law, order, or injunction prohibiting the issuance; (c) No Material Adverse Change shall have occurred since the Effective Date; (d) the Company shall be current in all required filings with the SEC and Nasdaq in all material respects; (e) the ADS shall remain listed and actively traded on Nasdaq; (f) the Company shall have a demonstrated need for the funds in order to maintain its "going concern" status as determined by the Company's auditors; (g) no event of default under this Agreement shall have occurred; (h) the Purchase Price for any Tranche shall not be less than the Minimum Price referenced in Section 4.3 above; and (i) the Exchange Cap referenced in Section 4.4 above has not been reached.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.2 Tranche Deferrals.**

Subscriber may defer (but not terminate) a Tranche if (i) trading in the ADSs is suspended or the ADSs are delisted, (ii) any legal restraint prohibits the issuance or deposit, or (iii) the Depositary/transfer agent is unable to process issuance/delivery of the Restricted ADSs despite good-faith efforts, in each case until resolved. Any deferred Tranche shall be consummated promptly following resolution of the applicable condition and, to the extent not resolved prior to expiration of the Commitment Period, the parties shall in good faith agree an extension solely to permit completion of such deferred Tranche(s).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.3 Use of Proceeds.**

**[REDACTED — Confidential Treatment Requested (Use of Proceeds)]**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.4 Most Favored Nation.**

**[REDACTED — Confidential Treatment Requested (Most Favored Nation)]**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.5 Termination Rights.**

Subscriber may terminate the Commitment upon written notice if the Company breaches this Agreement, the Company is or becomes insolvent, the ADSs are delisted, or a Material Adverse Change occurs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.6 Exchange Cap Enhancement.**

If shareholder approval is required to issue securities beyond the Exchange Cap, the Company shall use commercially reasonable efforts to obtain such approval within ninety (90) days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.7 True-Up Conversion.**

The parties acknowledge that the Subscriber has made, or caused to be made, prior payments to or for the account of the Company in the following amounts and on the following dates (the "True-Up Payments"): (a) US$271,797.68 on December 8, 2025; (b) US$112,500.00 on December 12, 2025; (c) US$775,000.00 on December 22, 2025; and (d) US$100,000.00 on January 15, 2026; totaling US$1,259,297.68 in aggregate. In consideration and full satisfaction of the True-Up Payments, the Company shall, simultaneously with the allotment and issuance of Ordinary Shares in respect of the initial Tranche under Drawdown Notice No. 1, allot and issue to the Subscriber (or its nominee, Guaranty Nominees Limited, as depositary nominee of JPMorgan Chase Bank, N.A.) a number of Ordinary Shares equal to the aggregate True-Up Payments (US$1,259,297.68) divided by the Purchase Price calculated for Drawdown Notice No. 1, rounded down to the nearest whole Ordinary Share. Based on the 5-day average Nasdaq Official Closing Price of $2.948 per ADS for the week of March 16-20, 2026, the True-Up Conversion results in the allotment of 922,687,200 new Ordinary Shares (representing 427,170 new Restricted ADSs). For the avoidance of doubt: (i) the True-Up Payments shall not count towards, and shall not reduce, the Commitment; (ii) the Ordinary Shares allotted in respect of the True-Up Conversion shall count towards the Exchange Cap referenced in Section 4.4; and (iii) no separate Drawdown Notice shall be required in respect of the True-Up Conversion.

**7. Miscellaneous**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7.1 Governing Law.**

This Agreement (and any non-contractual obligations arising out of or in connection with it) shall be governed by and construed in accordance with the laws of the State of Alabama. Notwithstanding the foregoing, the allotment and issuance of Ordinary Shares and all matters of UK corporate law (including the Company's articles and the Companies Act 2006) shall be governed by and construed in accordance with the laws of England and Wales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7.2 Entire Agreement; Amendments.**

**Item 1. Security and Issuer**

**(a) Title of Class of Securities:**
Ordinary Shares, nominal value GBP 0.001 per share

**(b) Name of Issuer:**
Argo Blockchain Plc

**(c) Address of Issuer's Principal Executive Offices:**
Eastcastle House, 27/28 Eastcastle Street, London, X0, W1W 8DH

**Item 4. Purpose of Transaction**

Item 4 of the Original Schedule 13D is hereby amended and supplemented by adding the following:

Subscription Facility Agreement

On March 26, 2026, the Issuer entered into a subscription facility agreement (the "Subscription Facility Agreement") with Growler, pursuant to which the Issuer may request up to US$5,000,000 in aggregate capital by delivering drawdown notices to Growler during the period ending March 26, 2027. Growler has agreed to fund each requested tranche, subject to the conditions of the Subscription Facility Agreement. Tranches are subject to a minimum of US$500,000 and a maximum of US$1,000,000 each, unless otherwise agreed by Growler in writing. Each drawdown requires: (i) unanimous board approval; (ii) auditor confirmation supporting a going-concern opinion in the relevant accounts; and (iii) representations and warranties of the Issuer true and correct in all material respects.

Pricing Mechanism

The subscription price per ADS for each tranche equals 100% of the average Nasdaq Official Closing Price of the Issuer's ADSs (Nasdaq: ARBK) over the five (5) trading days ending on the trading day immediately preceding the applicable drawdown notice date (the "5-Day NOCP"). Each ADS represents 2,160 Ordinary Shares of (pound)0.001 each. The subscription price is subject to a floor price per ADS and Nasdaq minimum pricing requirements under Listing Rule 5635(d).

Initial Tranche

On March 26, 2026, the Issuer delivered Drawdown Notice No. 1 to Growler requesting the Initial Tranche of US$2,500,000, which exceeds the standard per-tranche maximum; Growler agreed in writing to fund this above-standard amount as permitted by the Subscription Facility Agreement and also waived the standard 10-Trading Day notice period. The applicable 5-Day NOCP was US$2.948 per ADS (being the average of: US$3.03 on March 16, US$3.01 on March 17, US$2.89 on March 18, US$2.90 on March 19, and US$2.91 on March 20, 2026). At this price, the Initial Tranche results in the issuance of 847,693 Restricted ADSs (representing 1,831,016,880 Ordinary Shares) to Growler, with the Tranche Closing Date (ADS delivery) of April 9, 2026.

True-Up Conversion

Simultaneously with the Initial Tranche, the Subscription Facility Agreement provides for the conversion into equity of prior payments totaling US$1,259,297.68 made by or on behalf of Growler to or for the account of the Issuer, comprising: (a) US$271,797.68 on December 8, 2025; (b) US$112,500.00 on December 12, 2025; (c) US$775,000.00 on December 22, 2025; and (d) US$100,000.00 on January 15, 2026. The True-Up Payments are converted at the same subscription price as the Initial Tranche (US$2.948 per ADS), resulting in the issuance of 427,170 Restricted ADSs (representing 922,687,200 Ordinary Shares) to Growler. The True-Up Payments do not reduce the remaining availability under the Subscription Facility Agreement. The Ordinary Shares issued in respect of the True-Up Conversion count towards the Exchange Cap described below.

Exchange Cap

The Subscription Facility Agreement limits the aggregate number of new Ordinary Shares issuable thereunder to 19.99% of the Issuer's outstanding Ordinary Shares as of March 26, 2026, being approximately 5,768,648,865 Ordinary Shares (approximately 2,670,671 ADSs), unless shareholder approval is obtained. Taking into account the 2,753,704,080 Ordinary Shares issued in respect of the Initial Tranche and the True-Up Conversion, approximately 3,014,944,785 Ordinary Shares (approximately 1,395,808 ADSs) remain available under the Exchange Cap.

Registration Rights

The Subscription Facility Agreement requires the Issuer to file a resale registration statement on Form F-3 covering the Restricted ADSs issued thereunder within 45 days of March 26, 2026 (being on or before May 10, 2026) and to use commercially reasonable efforts to cause such registration statement to become effective as soon as practicable thereafter.

Continued Investment Intent

Each Reporting Person acquired the securities described in this Amendment in connection with the Subscription Facility Agreement and intends to review its investment in the Issuer on a continuing basis. Each Reporting Person may acquire additional securities of the Issuer pursuant to the Subscription Facility Agreement or otherwise, or may retain or, subject to applicable transfer restrictions under the Amended and Restated Restricted Issuance Agreement with JPMorgan Chase Bank, N.A. as depositary, sell or otherwise dispose of all or a portion of the securities held, at any time and from time to time without prior notice, depending on an ongoing evaluation of the Issuer's business, financial condition, operations and prospects; price levels of the Issuer's securities; general market, industry and economic conditions; and other future developments. The Reporting Persons do not currently have any plan or proposal that would result in or relate to any of the transactions or changes enumerated in paragraphs (a) through (j) of Item 4 of Schedule 13D other than as described herein.

**Item 5. Interest in Securities of the Issuer**
