Argo names new CFO; Nasdaq grants conditional continued listing

Argo Blockchain plc announced the promotion of Charlotte Proctor-Worrall to Chief Financial Officer, effective immediately.

Rhea-AI Filing Summary

Argo Blockchain plc announced the promotion of Charlotte Proctor-Worrall to Chief Financial Officer, effective immediately. She joined Argo in 2021, has served as Group Financial Controller, built the finance function across the UK, US and Canada, led annual audits, managed IFRS and SEC reporting, overseen treasury across fiat and crypto, and supported capital markets and restructuring work.

The filing also updates Argo's Nasdaq status: after a hearing on 26 August 2025, the Nasdaq Hearings Panel granted Argo continued listing on The Nasdaq Global Select Market provided Argo demonstrates compliance with all listing rules by 14 January 2026. The Panel took Argo's Part 26A recapitalization process into account. The company states there is no assurance it will regain or maintain compliance and notes potential delisting risk if requirements are not met.

Positive

• Promotion of an experienced internal finance leader to CFO may improve reporting, controls and execution of recapitalization efforts
• Nasdaq Hearings Panel granted continued listing through 14 January 2026, avoiding immediate suspension or delisting

Negative

• Continued listing is conditional and time-limited; failure to demonstrate compliance by 14 January 2026 could lead to delisting
• No assurance provided that Argo will regain the minimum bid price or maintain all Nasdaq listing rule compliance

Insights

Corporate Finance Analyst

TL;DR: CFO promotion strengthens internal finance capability while Nasdaq conditional relief buys time for recapitalization.

The appointment of Charlotte Proctor-Worrall to CFO formalizes leadership continuity and preserves institutional knowledge during a material recapitalization process; her experience with IFRS, SEC reporting and treasury is directly relevant to restoring Nasdaq compliance. The Nasdaq Panel's decision to grant continued listing through 14 January 2026 is materially positive in the short term because it prevents immediate delisting, but it is conditional and time-limited. The market impact depends on Argo's ability to complete the Part 26A recapitalization with Growler and to restore the minimum bid price and other listing rule compliance before the deadline.

Corporate Governance Specialist

TL;DR: Governance continuity is reinforced, but conditional listing highlights ongoing regulatory and execution risks.

Promoting an internal finance leader to CFO signals governance stability and may reassure stakeholders about the company’s reporting and internal control capabilities during restructuring. The Nasdaq Panel’s conditional continued listing recognizes the company’s ongoing recapitalization under UK law but explicitly leaves the outcome dependent on future compliance. Investors should treat the Panel decision as temporary relief rather than resolution; the filing appropriately discloses the risk of eventual delisting if compliance is not achieved.

EXHIBIT INDEX

Exhibit No.     1 Description Appointment of CFO and Nasdaq Listing Update dated 22 September 2025

Press Release

22 September 2025

Argo Blockchain plc

("Argo" or "the Company")

 Appointment of Chief Financial Officer and Nasdaq Listing Update

The Company is pleased to announce the promotion of Charlotte Proctor-Worrall to the position of Chief Financial Officer, effective immediately.

Charlotte joined Argo in 2021 and has served as Group Financial Controller since that time. She has built the Company's finance function from the ground up, overseeing all core processes, controls, and reporting frameworks across the UK, US, and Canada. She has led multiple annual audits, managed Argo's IFRS and SEC reporting, overseen treasury and liquidity across fiat and crypto assets, and supported Argo's capital markets and restructuring initiatives.

Justin Nolan, Chief Executive Officer of Argo, said:

"Charlotte will be an invaluable member of our leadership team. She has not only strengthened Argo's financial operations and reporting, but also played a pivotal role in advancing our recently announced strategic transaction with Growler. Her promotion to CFO reflects her proven leadership and the trust she has earned across the business."

Nasdaq Listing Update

As previously announced, on 18 July 2025, Argo received a letter from the Listing Qualifications Department (the "Staff") of The Nasdaq Stock Market LLC ("Nasdaq") notifying Argo that because it has not regained compliance with the minimum bid price requirement set forth in Nasdaq Listing Rule 5450(a)(1), the Staff had determined to delist Argo's American Depositary Shares ("ADSs") from The Nasdaq Global Select Market. Argo submitted a request for a hearing before the Nasdaq Hearings Panel (the "Panel"), which stayed any suspension or delisting action pending issuance of the Panel's decision following the hearing.

A hearing before the Panel was held on 26 August 2025.

The Company is pleased to announce  that following the hearing, on 18 September 2025, Argo was notified by Nasdaq that the Panel had granted Argo's request for continued listing on The Nasdaq Global Select Market, subject to the condition that Argo demonstrates compliance with all applicable listing rules on or before 14 January 2026. The Panel considered Argo's recapitalization process under Part 26A of the UK Companies Act and determined that Argo's continued listing request should be granted so as to allow it to complete that process.

Argo remains focused on delivering its strategic recapitalization in partnership with Growler Mining, LLC n/k/a Growler Mining Tuscaloosa, LLC and will continue to update the market on material developments.

There can be no assurance that Argo will be able to regain compliance with the minimum bid price requirement or will otherwise maintain compliance with all other applicable Nasdaq Listing Rules. Argo's failure to meet these requirements could result in Argo's ADSs being delisted from The Nasdaq Global Select Market.
