Haydale Establishes Strategic Digital Infrastructure to Support Recurring Revenue Model

Haydale (AIM: HAYD), the advanced materials and clean-technology group, today announces the launch of an integrated subscription model across its SaveMoneyCutCarbon ("SMCC") operations and JustHeat product deployments, supported by a Strategic Platform Partnership Agreement (the "Platform Partnership").

The initiative represents a deliberate shift towards recurring, multi-year revenue relationships, combining product deployment, digital services and subscription-based payment structures within a unified commercial framework.

Highlights

•      Launch of integrated subscription model: Introducing recurring, multi-year revenue structures combining subscription-based carbon accounting, verification, compliance and carbon finance capability for Group customers, to be offered through SMCC.

•     Strategic platform partnership secured: Strategic platform agreement entered into with Quidos Technologies Limited, providing scalable digital infrastructure, including carbon accounting, verification and environmental credit systems, underpinning the subscription model.

•        Advances core strategic objective: Enhances revenue visibility and quality through recurring income streams while increasing lifetime customer value and supporting scalable installation growth.

Integrated Subscription Model

The Group engages with thousands of business customers annually through SMCC and its impact partner network. The new subscription model converts this engagement into structured, recurring relationships that integrate:

·      carbon accounting and decarbonisation planning tools;

·      compliance-ready reporting and performance dashboards;

·      emission reduction verification capability; and

·      access to environmental credit infrastructure.

This structure enhances revenue visibility and quality by introducing recurring digital and service income on a subscription model alongside product deployment.

The Board believes this model strengthens lifetime customer value while improving predictability of revenue streams.

Platform Infrastructure

Delivery of the subscription model is enabled through the Platform Partnership with BEClimate ("BEC"), part of Quidos Technologies Limited ("Quidos"), further details of which are set out below.

Under this agreement, the Group gains access to:

·      carbon accounting and decarbonisation action planning software (BEScope),

·      verification infrastructure to quantify and report emission reductions (BEVerify), and

·      transaction capability enabling monetisation of verified impact where eligible (BEXchange).

This infrastructure allows SMCC and JustHeat deployments to be digitally measured, verified and, where appropriate, monetised, supporting recurring subscription income.

BEClimate is an integrated climate infrastructure platform purpose-built for buildings, construction and materials. It has been developed to address structural barriers that have historically constrained credible climate finance in the built environment, including the absence of verifiable project baselines, real-time measurement capability, analogue verification processes and multi-year issuance cycles.

BEClimate is underpinned by Quidos, a government-accredited energy efficiency group operating nationally recognised assessment schemes and widely adopted carbon data and software platforms across the UK real estate and construction sectors since 2006. This regulatory depth and operational footprint, combined with senior team experience across carbon markets, registry infrastructure, MRV design and climate finance, provides a robust institutional foundation for high-integrity infrastructure, supporting scalable climate finance while preserving transparency, auditability and methodological rigour.

The Platform Partnership involves payment of a £50,000 one-off onboarding, configuration and integration fee and £50,000 per quarter during the initial term of three years. The quarterly payments are subject to volume-linked rebate mechanisms under which platform-generated revenues are applied against those amounts. At anticipated operating volumes, these rebates are expected to fully offset the quarterly payments in due course.

The agreement includes customary service-level obligations, regulatory compliance representations and termination provisions.  As a strategic anchor partner, the Group benefits during the initial term from preferential commercial terms across platform services, including enhanced re-seller terms and programme-supported access to verification and exchange capability.

The entering into of the Platform Partnership with Quidos (the "Transaction") constitutes a related party transaction pursuant to Rule 13 of the AIM Rules for Companies by virtue of Quidos being a 10.3% shareholder of the Company and Simon Turek, Chief Executive Officer of Haydale, holding a 39.2% interest in Quidos. Jeremy Nesbitt, Non-Executive Director of Haydale, is also a Non-Executive Director of Quidos so has taken no part in the approval of the Platform Partnership.

The independent directors for the purposes of the Transaction, being all Directors excluding Simon Turek and Jeremy Nesbitt, consider, having consulted with the Company's nominated adviser, Cavendish Capital Markets Limited, that the terms of the Transaction are fair and reasonable insofar as the Company's shareholders are concerned. The Board considered alternative providers and standalone development options and concluded that equivalent carbon accounting and decarbonisation action planning software, verification, reporting and transaction infrastructure independently would involve materially higher capital and operational expenditure, extended development timelines and greater operational risk than the agreed strategic partner fee.

Mark Sait, Chief Commercial Officer, commented:

"Today's announcement reflects the commercial evolution of our platform.

Through SMCC and our impact partner ecosystem, we already engage with thousands of businesses seeking support to reduce energy costs, manage carbon reporting and improve efficiency. The launch of our subscription model provides a structured, scalable way to serve that demand and on a recurring basis.

This significantly increases our ability to scale across both digital services and physical product deployment."

Gareth Kaminski-Cook, Chair, commented:

"This announcement represents a deliberate step in Haydale's transition toward a broader decarbonisation platform.

We are transitioning from one-off deployments to recurring relationships with businesses at scale. Through our impact partners, we have access to a substantial business customer base, and the subscription model provides the mechanism to serve that opportunity.

Importantly, this initiative enhances the quality and visibility of our revenue, introducing scalable subscription economics alongside our product-led growth."
