Inside the all-scrip deal: what Energy One is paying
The proposed transaction is structured as an all-scrip acquisition, with Energy One to issue 7,089,780 Energy One shares (Consideration Shares) to Fluxys as sole consideration for 100% of GMSL’s issued capital.
This implies an Enterprise Value of A$99.8m, based on a 15-day VWAP of $14.08. The Consideration Shares will be subject to a 12-month voluntary escrow period, subject to agreed exceptions.
Following completion, Fluxys is expected to hold approximately 18.26% of Energy One and become the company’s largest shareholder.
| Metric | Detail |
|---|---|
| Consideration | 7,089,780 EOL shares (all-scrip) |
| Implied Enterprise Value | A$99.8m |
| Basis | 15-day VWAP of $14.08 |
| Fluxys post-completion holding | ~18.26% |
| Escrow | 12-month voluntary escrow |
| Expected completion | November 2026 |
Why the numbers matter for shareholders
The financial case centres on accretion. Energy One expects the transaction to be approximately 35% FY26A pro forma EPS accretive, a material uplift for existing shareholders.
The enterprise value represents approximately 9.4x FY26A pro forma EBITDA before identified synergy benefits. Post-completion, the combined group’s European revenue exposure is expected to rise to approximately 70% of group revenue.
Beyond the headline multiple, Energy One has identified potential synergy benefits:
-
Potential EBITDA benefits of up to approximately A$4.1m per annum, comprising revenue opportunities and operational efficiencies
-
Full realisation targeted by the end of FY28
The deal is positioned to increase exposure to high-quality recurring revenue and expand operating leverage across a larger platform.
Chairman Commentary
“This transaction is closely aligned with Energy One’s long-term strategy and is expected to create value for shareholders. GMSL strengthens our European platform, deepens our software and services capability and brings Fluxys onto the register as a long-term strategic partner. We believe the transaction is a compelling opportunity to accelerate growth while preserving the strengths that have driven Energy One’s performance,” said Andrew Bonwick, Chairman.
What GMSL brings to the table
GMSL is a wholly owned subsidiary of Fluxys, a Belgian energy infrastructure group, providing energy market software, 24/7 operational services and market connectivity solutions for gas and power companies across Europe.
The business operates at meaningful scale:
-
Over 100 staff providing operations services and software
-
Operations across 18 European gas networks and 15 European power grids
-
Works with more than 100 shippers, traders and utility companies
-
Specialist capability in nominations, scheduling, balancing and 24/7 managed operations
These are mission-critical, highly embedded workflows.
A strategic fit that accelerates the One-Stop-Shop model
Energy One frames the acquisition as the next step in its proven Software + Services growth strategy and the evolution of its One-Stop-Shop strategy to build a broader, more capable platform for energy market participants.
The GMSL acquisition is the most significant strategic move Energy One has made since its Volue takeover rejection in July 2026, when the board unanimously dismissed a $550m-plus all-cash bid as opportunistic and insufficient, reaffirming its commitment to standalone growth through disciplined M&A.
The addition of GMSL is intended to enhance scale and operating leverage across European gas and power markets, while broadening cross-sell and upsell opportunities across the combined customer base.
The Fluxys relationship remains central. GMSL will continue providing services to Fluxys under existing agreements, positioning Fluxys as a long-term strategic partner and reflecting continued confidence in the growth potential of the combined group.
CEO Commentary
“GMSL is a highly complementary business with mission-critical capability, deep customer relationships and specialist expertise in European gas and power market operations. Bringing GMSL into the Energy One group accelerates our European strategy and strengthens our one-stop-shop proposition. Together, we will have greater scale, broader capability and a more integrated software and services platform across the energy trading lifecycle,” said Benjamin Tranier, CEO.
The road to completion: conditions and Fluxys’s new rights
Completion remains conditional upon the satisfaction or waiver of various conditions precedent:
-
Energy One shareholder approval, including approval required under ASX Listing Rule 7.1
-
Fluxys obtaining foreign investment approval under the Foreign Acquisitions and Takeovers Act 1975 (Cth)
-
Energy One’s continued ASX quotation
Either party may terminate the agreement if these conditions are not satisfied or waived by 1 March 2027, or such later date agreed between the parties.
In connection with the agreement, Energy One has granted certain Board nomination rights to Fluxys for so long as it maintains a holding of at least 10%:
-
One director while holding equal to or more than 10% and less than 20% of total issued shares
-
Two directors while holding equal to or more than 20% of total issued shares
The Energy One board unanimously recommends, in the absence of a superior proposal, that shareholders vote in favour, with each director intending to vote all shares they hold or control in favour. The agreement also provides for a reverse break fee of £3,000,000 payable in defined circumstances.
Energy One expects completion by November 2026, with further details to be provided to shareholders in the Notice of Meeting and accompanying explanatory materials.
