Energy One completes GMSL acquisition and welcomes Fluxys as largest shareholder
Energy One Limited (ASX:EOL) has completed the acquisition of 100% of the issued share capital of Gas Management Services Limited (GMSL) from Fluxys UK Limited (Fluxys). GMSL is now a wholly owned subsidiary of Energy One.
Energy One issued 7,089,780 fully paid ordinary shares (Consideration Shares) to Fluxys as consideration. Fluxys now holds approximately 18.26% of Energy One’s issued shares and is its largest shareholder.
The A$99.8 million all-scrip deal was priced at 9.4x EBITDA before synergies, with management targeting up to A$4.1 million in annual EBITDA synergies by the end of FY28.
Erik Vennekens has joined the Board as Fluxys’ nominee director. The transaction was first announced on 19 August 2026.
Benjamin Tranier, Energy One CEO
“GMSL is a highly complementary business for Energy One that strengthens our European platform and our One-Stop-Shop proposition. […]”
With completion confirmed on 30 October 2026, the acquisition is no longer pending, which removes the risk of non-completion for investors.

How the deal got over the line
Completion followed satisfaction of all conditions precedent, including foreign investment approval and shareholder approval. The key steps were:
- 19 August 2026: Transaction announced
- 2 October 2026: Foreign investment approval under the Foreign Acquisitions and Takeovers Act 1975 (Cth) announced
- 15 October 2026: Shareholder approval at the Extraordinary General Meeting
- 30 October 2026: All conditions precedent satisfied and Completion
The Fluxys group will continue to provide transition services to GMSL for six months following Completion. GMSL will continue to provide its services to Fluxys group members under existing agreements, which may be supplemented by additional, long-term arrangements pursuant to the terms of a Master Services Agreement.
For investors, this points to continuity in existing Fluxys group relationships and a structured handover.
What GMSL adds to Energy One
GMSL provides software and 24/7 operational services for gas and power companies across Europe. It supports gas and power shippers through operations services and software.
| Metric | Detail |
|---|---|
| Staff | Over 100 |
| European gas networks | 18 |
| European power grids | 15 |
| Clients | More than 100 leading shippers, traders and utility companies |
The profile gives Energy One additional scale and a customer base in Europe, aligned with its stated European platform and One-Stop-Shop strategy.
Wholesale energy trading software explained
Wholesale energy trading software helps energy companies manage the buying and selling of gas and power. Energy One describes itself as a provider of wholesale energy trading software and services, supporting customers across the energy trading lifecycle through:
- Software
- Market operations
- Scheduling
- Settlements
- Compliance
- Advisory services
A shipper is a company that moves gas or power through a network on behalf of its own trading or supply activity.
Bundling software with operational services means a customer can draw on both from one provider. That ties directly to the One-Stop-Shop proposition that management says GMSL strengthens.
Fluxys as strategic partner and Board changes
Shareholding and escrow
The Consideration Shares are subject to voluntary escrow until 12 months after the date of Completion, subject to agreed exceptions. An Appendix 2A for the quotation of the Consideration Shares has been lodged with ASX.
The escrow arrangement points to a longer-term holding by Fluxys and limits near-term selling of the shares.
Erik Vennekens joins the Board
Mr Vennekens has been appointed as a Non-Executive Director and a member of the Risk & Audit Committee, with effect from Completion. He has extensive experience in the European energy and infrastructure sector, with senior leadership responsibilities across asset management, major project delivery and business transformation.
At Fluxys, he has been involved in the development and delivery of strategic energy infrastructure, including natural gas, LNG, hydrogen and CO₂ projects. His experience also covers digital transformation, governance and organisational leadership.
Fluxys nominated him under its right to nominate one director for as long as it holds equal to or more than 10% of the total issued Energy One shares. The Board does not consider him an independent director.
Andrew Bonwick, Energy One Chairman
“On behalf of the Board, I am pleased to welcome Erik to Energy One. […] his appointment reflects the long-term strategic partnership between Energy One and Fluxys. We look forward to his contribution to the Board.”
What happens next for Energy One and GMSL
Several arrangements now run from Completion:
- Transition services: The Fluxys group will continue to provide transition services to GMSL for six months following Completion.
- Voluntary escrow: The Consideration Shares are escrowed until 12 months after the date of Completion, subject to agreed exceptions.
- Master Services Agreement: Existing agreements between GMSL and Fluxys group members may be supplemented by additional, long-term arrangements pursuant to the terms of a Master Services Agreement.
The integration of GMSL and the relationship with Fluxys underpin Energy One’s stated growth ambitions in Europe.
Those growth ambitions build on Energy One’s FY26 results, which showed 17% recurring revenue growth to $63.5m and a net cash position, giving the company capacity to pursue further M&A.
