Exercise of Warrants

GreenRoc Strategic Materials Plc (AIM: GROC), a company focused on the development of critical mineral projects in Greenland, announces the assessment results in respect of its annual Environmental, Social, and Governance ("ESG") submission to Digbee ESG. The Company also announces receipt of a notice to exercise warrants over a total of 1,153,846 new ordinary shares of 0.1 pence each in the Company ("Shares") at an exercise price of 2 pence per Share, raising £23,076.92 for the Company.

Annual Digbee ESG assessment reporting

GreenRoc has achieved an independent ESG rating of BB following its latest annual submission to Digbee ESG. The BB rating is an average rating consisting of a corporate ESG rating of BBB and a project ESG rating of BB. The corporate BBB rating is an improvement from the previous BB rating announced on 25 February 2025 and reflects the initiatives implemented by GreenRoc during the past 12 months.

Digbee is the mining sector's foremost independent assessment platform for sustainability disclosure, endorsed by leading global financiers. The Digbee ESG assessment is conducted by an independent panel of globally recognised sustainability experts.

About the Digbee ESG Assessment

GreenRoc undertook and submitted a Digbee ESG disclosure in January 2026. This comprised the completion of a set of comprehensive corporate and project questionnaires appropriate to the stage of its Amitsoq project and mapped to Global Standards. The questionnaires required provision of relevant data, narrative and supporting evidence. The disclosure was assessed by independent mining ESG experts in order to produce an impartial rating.

The overall BB rating is in the top-five category and reflects some of the uncertainties related to the early development stage for both the Company and the Amitsoq project. Thus, the scoring range for the Amitsoq project is from CC to AA, while for the Company it is B to A. Generally speaking, the overall average of BB represents a 'Neutral' rating.

Exercise of warrants

Application will be made for the 1,153,846 Shares issued in respect of the notice of exercise of warrants to be admitted to trading on AIM, which is expected to occur on or around 2 April 2026 ("Admission"). The Shares will rank pari passu in all respects with the ordinary shares of the Company currently traded on AIM.

Following Admission, the Company's issued share capital will comprise 283,695,707 ordinary shares of 0.1p each. This number will represent the total voting rights in the Company and may be used by shareholders as the denominator for the calculation by which they can determine if they are required to notify their interest in, or a change to their interest in, the Company under the Financial Conduct Authority's Disclosure and Transparency Rules.

GreenRoc's CEO, Stefan Bernstein, commented:

"We are pleased to have received an average 'Neutral' BB rating in our second Digbee ESG assessment addressing GreenRoc's activities both at the Amitsoq project and the corporate level. We are also proud to be one of the few mineral exploration companies with an independent ESG certification, a testament to GreenRoc's commitment to responsible development and transparency at this relatively early stage of the Amitsoq project. This impartial rating provides valuable insight into our current ESG standing and we recognise that there are opportunities for improvement as we progress. We remain dedicated to strengthening our environmental, social and governance practices as our projects evolve, ensuring we deliver long-term, sustainable value for all stakeholders."

About GreenRoc

GreenRoc Strategic Materials Plc is an AIM-quoted UK public company focused on developing the Amitsoq Graphite Project in Greenland into a producing mine to meet critical demand from Electric Vehicle manufacturers in Europe and North America for new, high grade and conflict-free sources of graphite. 

Amitsoq is one of the highest-grade graphite deposits in the world with a combined Measured, Indicated and Inferred JORC Resource of 23.05 million tonnes (Mt) at an average grade of 20.41% graphite, sufficient to sustain several decades of mining.

The plans for the Amitsoq Project include the construction of a facility to further process mined graphite into active anode material ("AAM") - an indispensable component of Li-batteries - which plans have been independently and positively evaluated to the prefeasibility stage. GreenRoc has entered into a memorandum of understanding with the Norwegian battery manufacturer Morrow Batteries to establish a regional AAM supply chain.

GreenRoc received an Exploitation Licence for the Amitsoq Project from the Government of Greenland in December 2025, valid for 30 years, and the Project has been designated a Strategic Project by the EU.

In October 2025, GreenRoc secured a loan facility of EUR 5.2 million from the Export and Investment Fund of Denmark ("EIFO") for the financing of the Company's work programme, including the construction of a pilot AAM plant in Denmark which is in progress and expected to be completed during 2026.

In December 2025, GreenRoc and its consortium partners DTU and IPU were granted up to ca. £1.2m of grant funding for the project entitled "EU-Graphite: Building European production of graphite active anode material" ("EU-Graphite") from the Energy Technology Development and Demonstration Programme ("EUDP"), a Danish government funding programme, which funds will be utilised to develop GreenRoc's plans to achieve a more sustainable and environmentally friendly alkaline-based purification process for its anode material.

Both GreenRoc and the Amitsoq Project have been ESG-certified by Digbee™, an independent platform which provides sustainability assessments for the mining industry.
