Quantum Data Energy (LON: MAST) Advances Non-Dilutive Funding for 300 MW Flexgen Portfolio

QDE Makes Significant Progress with Growth Funding at Project Level

Quantum Data Energy PLC has advanced its plans to secure non-dilutive, project-level funding to accelerate both its flexible generation developments and a pipeline of opportunistic acquisitions, targeting a portfolio exceeding 300 MW. The company has brought in Sustainable Investing Solutions to lead the fundraising effort, which is expected to support around 40 MW of new projects and enable the purchase of operational flexgen assets.

The capital will be raised at the SPV level, allowing Quantum Data Energy to retain equity stakes and gain additional revenue streams without committing further corporate funding. The company expects to reach financial close with at least one investor in the first quarter of 2026.

As of December 1, the company has 138,760,735 ordinary shares in issue with voting rights.

Partnership with Sustainable Investing Solutions

SIS was founded by David Short and operates in partnership with Helen Wade of Andaman Energy & Infrastructure. Together, they bring nearly six decades of senior-level experience in sustainable infrastructure, investment banking, portfolio management, and restructuring. Their combined track record includes more than $22.5 billion of transactions across global sustainable infrastructure markets.

The partnership provides QDE with access to a broad capital network—including banks, institutional investors, funds, private investors, and family offices—and benefits from FCA approval and FSQS registration.

Project Finance Plan

Working with HW&DS, QDE developed a two-part project finance strategy:

• Component 1 – Development Capex
Funding for QDE’s existing c.40 MW development portfolio to progress each asset through construction and into operation.

• Component 2 – Acquisitions
A strategy to acquire portfolios of existing operational flexgen sites totalling around 300 MW.

Both components will use SPV-level financing. QDE will retain a material equity interest, hold rights to earnings, secure ROFR rights over majority shareholders’ stakes, and maintain exclusivity to provide management services—creating an additional income stream.

Market Opportunity

During 2024 and early 2025, an estimated 1,449 MW of operational flexgen assets entered the market, driven in part by funds seeking to crystallise tax benefits, including through tax-loss harvesting. Additional capacity is expected to become available as investors reassess portfolios, underscoring a robust pipeline of opportunities.

Acquiring operational assets offers immediate cash generation and typically requires lower capital per MW compared with new build projects, enabling QDE to accelerate scale at lower cost.

HW&DS has already initiated discussions with a select group of preferred investors and anticipates first financial close with at least one investor in Q1 2026.

Executive Commentary

Pieter Krügel, CEO of Quantum Data Energy PLC, said:
“Helen and David are leaders in sustainable energy investment with a long history of delivering successful transactions. Their selectivity in client engagement gives us strong confidence in securing the project-level capital needed to execute our growth strategy. We look forward to advancing toward financial close.”

David Short, CIO of Sustainable Investing Solutions, added:
“Flexgen assets are essential for achieving net-zero targets and ensuring grid stability. QDE’s focus on small-scale sites near population centres offers a compelling investment profile—ETS-exempt, eligible for additional ancillary services income, and benefiting from grid connection prioritisation. All sites are being future-proofed for green-gas integration, which enhances long-term value.”
