Conditional Acquisition of D3IP Limited
Entry into UK Defence

Binding agreement to acquire the entire issued share capital, subject to conditions

Technology Minerals Plc (LSE: MNTL), the UK listed company focused on building national resource and manufacturing resilience which trades as Mantle, is pleased to announce that it has entered into legally binding heads of terms (the "Heads") to acquire the entire issued share capital of D3IP Limited ("D3IP") from DII (Group) Ltd (the "Proposed Acquisition"). Completion remains subject to the conditions set out below.

The Proposed Acquisition of D3IP - a cash generative, profit-making business - provides Mantle with an entry point into the UK defence market. It is the delivery vehicle for a live defence contract with the Ministry of Defence and sits within a group that holds framework positions with defence and national-security customers. It is in line with Mantle’s strategy to build and connect businesses that strengthen the UK’s sovereign capability and supports the Company’s ambition to create an ‘Enabling Ecosystem’ to proactively bring together the companies, expertise, infrastructure and capital the UK needs to deliver that critical capability faster.

Highlights

• A route into UK defence. D3IP provides Mantle with an operating company in the ecosystem through which the UK specifies, buys and fields the capabilities on which its security and resilience depend.
• An established, profitable operating business. D3IP already works with the organisations responsible for specifying, procuring and deploying the UK's security capabilities. It is the Company’s first step towards fulfilling its operating company vision: revenue generating, profit making, strategically aligned.

• Visibility of supply chain demand. Mantle will gain visibility of a growing vetted ecosystem of, currently, 300 defence and national-security adjacent technology and services businesses and their supply-chain and manufacturing requirements. The Board regards that visibility as a practical demand signal for the capabilities Mantle is being built to own and scale.
• A route into frameworks that otherwise take years to reach. The proposed arrangements include access, for D3IP, to relevant current and future frameworks held by DII Ltd and affiliated companies. That access is intended to enable Mantle to support delivery into defence and national-security customers.

• A structured path across the Wider Group. The Heads include exclusivity and option arrangements over other DII Ltd affiliated companies, so that Mantle and the existing owners can work together, over a three-year horizon, towards a shared objective of keeping critical UK digital, defence and national-security capability in trusted hands.

Rationale for the Proposed Acquisition

The UK Government must respond quickly to fast-changing security needs while keeping access to trusted technology and specialist suppliers. D3IP helps meet those needs by shortening the time between identifying a requirement and having a tested, potentially deployable solution. It also gives suppliers credible routes into defence and national security markets that can otherwise be difficult to access.

UK defence and national-security customers buy through frameworks, dynamic purchasing systems and vetted supply chains. Qualifying for them takes track record, security standing and time. That is the main barrier between a company building sovereign materials and manufacturing capability, as Mantle is, and the customers who need that capability. D3IP helps to remove that barrier.

D3IP is expected to provide the Group with an operating platform through which its wider strategy can be developed. It complements the materials and manufacturing work already in the Group, providing access to programmes, frameworks and partner companies that require those capabilities. Completing the Proposed Acquisition would therefore be both a first operating asset under the Mantle strategy, and a window onto the demand the rest of the strategy is designed to meet.

Consideration

The total consideration for the Proposed Acquisition is subject to a floor of £1.2 million and a ceiling of £4.5 million, payable as follows:

• £1.0 million on completion, comprising £200,000 in cash and £800,000 in new ordinary shares in the Company;
• a further £200,000 in cash on or before 31 October 2026;
• two deferred tranches of £650,000 each, payable if the commercial route to defence is renewed or replaced for at least 12 months, and if the related revenue stream then continues;
• an additional earn-out of up to £2.0 million may become payable against agreed milestones such as a material uplift in revenue, subject always to the £4.5 million ceiling.

Nick Bridle, Chief Operating Officer of Technology Minerals Plc, said:

“Mantle’s mission is to strengthen the security and resilience of the United Kingdom - by building and owning the capabilities that address the country’s strategic needs, and by putting them into a listed vehicle that can take them to scale. D3IP is the first example of that mission in action. It is already profitable. It already sits inside the defence and national-security ecosystem. And it gives us sight of the demand that the rest of the Group is here to meet. We are looking forward to working with the excellent team at D3IP as we continue to drive our mission forward.”

About Mantle – www.mantleresilience.com

Mantle exists to build and connect the critical sovereign capabilities the UK's security and resilience require. The UK remains dependent on supply chains it does not control and on industrial capacity it cannot always scale at pace. The Company's work is to shorten those chains, to put manufacturing and systems integration onshore, and to give the resulting businesses a credible route into defence, national security and other strategically important markets.

The strategy aligns with the Strategic Defence Review 2025 and supports the UK Government's Critical Minerals Strategy (Vision 2035), including its objectives for greater domestic production and recycling and reduced reliance on single-country supply.

D3IP Limited

D3IP Limited is a private company incorporated in England and Wales on 24 March 2026, the entire issued share capital of which is owned by DII (Group) Ltd. Timothy Andrew Harris and Richard David Bosworth are the directors of the seller and of D3IP.

D3IP is to be the delivery vehicle for the commercial route to defence currently contracted through its sister company, DII Ltd (DII Ltd and X-Net (Services) Ltd together with certain related entities, the "Wider Group").

D3IP is a new company holding an established business. It was incorporated on 24 March 2026 to separate the Wider Group’s defence delivery business into a standalone company that could be further developed across multiple sectors, with DII Ltd remaining the named prime contractor. The Wider Group has worked with defence and national-security customers since 1996. What gives D3IP its value was built by the Wider Group over that period and is brought into D3IP under the accompanying deeds described under Principal terms below. Execution of those deeds is a condition of completion, so the Company will not acquire D3IP without them. The consideration is also structured around D3IP's short corporate history, with £1.3 million payable only if the commercial route is renewed and its revenue continues under the Company's ownership.

The revenue and profit figures in this announcement have been provided by the sellers as unaudited management information and represent the annualised run-rate of the business now held by D3IP, not D3IP’s own trading since incorporation. They have not been independently verified by the Company and should not be read as a profit forecast.

Principal terms

Under the Heads the Corporate Seller has agreed to sell, and the Company has agreed to buy, the entire issued share capital of D3IP with full title guarantee, free from encumbrances, subject to the conditions. The Company may nominate a wholly-owned subsidiary to take the transfer. The listed company remains liable for the buyer's obligations.

Near-term consideration, which is not contingent on the commercial route to defence, is £1.2 million. The floor, if the two defence-route deferred legs also become payable, is £2.5 million. The ceiling, including earn-out, is £4.5 million.

Waterfall

Tranche	Amount	When	Form
1A	£200,000	Completion	Cash to the Corporate Seller
1B	£800,000	Completion	New ordinary shares in the Buyer
2	£200,000	On or before 31 October 2026	Cash to the Corporate Seller
3	£650,000	Renewal Condition satisfied	Cash (up to 25% Shares at Buyer’s election)
4	£650,000	Continuation Condition satisfied	Cash (up to 25% Shares at Buyer’s election)
5	Up to £2,000,000	Earn-out over 36 months from Completion	Cash, shares or mix; cannot exceed Ceiling nor more than 20% settled in shares.

Tranches 1A, 1B and 2 are not contingent on the commercial route to defence. Tranches 3 and 4 are contingent only on the renewal and continuation conditions described above. The parties' working assumption is that those conditions are tested by reference to 23 May 2027 and 23 May 2028 respectively.

Tranche 5 is an earn-out of up to £2.0 million over 36 months from completion against revenue, margin and new-contracted-work tests, always capped so that aggregate consideration does not exceed £4.5 million. An amount counted towards Tranche 3 or 4 is not also counted towards an earn-out milestone.

Consideration shares. The number of new ordinary shares for Tranche 1B is £800,000 divided by the agreed issue price, rounded down to the nearest whole share. If no price is agreed before completion, the issue price is the volume-weighted average price of an ordinary share in the Company on the Main Market for the five dealing days ending on the dealing day immediately before completion. The Company intends to issue those shares under authorities already in force. The shares will be issued in certificated form, subject to a lock-in of 12 months from admission and to orderly-market restrictions for a further 12 months. Application will be made for their admission to the Official List and to trading on the Main Market.

Related arrangements

Completion cannot occur until the following accompanying deeds have been executed. They are not optional side letters.

Defence-route subcontract. While DII Ltd remains the named prime, the benefit and burden of delivery and cash on the commercial route to defence are transferred back-to-back to D3IP.

Framework access agreement. D3IP is to have an exclusive, irrevocable right to bid, win and deliver under current and future relevant frameworks, dynamic purchasing systems, dynamic markets and successor vehicles held by the Wider Group, royalty-free or at a nominal fee, surviving change of control of any holder, with an 18-month tail after the option period ends.

Relationship and option agreement. The Company is to have an exclusive option, exercisable subject to conditions, to acquire 100 per cent of the Wider Group companies during a three-year option period, together with a no-shop and standstill, a right of first refusal over relevant opportunities, information rights, and reciprocal protections so that the option companies are not hollowed out.

Customary group, clearance and transitional arrangements are also to be executed. The Heads impose exclusivity and a no-shop on the seller parties from signing until the earlier of completion, the longstop date and any termination of the Heads.

Conditions and longstop

Completion is subject to the following conditions being satisfied or waived on or before 31 October 2026 (or such later date as the parties agree in writing):

(a) execution of the accompanying deeds, remaining in full force;

(b) execution of the share purchase agreement, disclosure letter and lock-in agreements in agreed form;

(c) no material adverse change in the business, the commercial route to defence, or D3IP's assets, liabilities or prospects between signing of the Heads and completion; and

(d) the fundamental warranties of title, capacity and ownership of the sale shares remaining true at completion.

The parties are obliged to negotiate the definitive documents in good faith and to use all reasonable endeavours to execute them before the longstop.

There can be no certainty that the conditions will be satisfied or that the Proposed Acquisition will complete. A further announcement will be made on execution of the share purchase agreement and on completion, as appropriate.
