Invinity Energy Systems Posts 2024 Results as ENDURIUM Transition Advances

• Lithium’s Loss is Flow’s Gain: High-profile safety incidents (e.g., Moss Landing) and geopolitical supply chain risks are pushing major LDES procurement programmes (UK, Ontario, California, New York, Australia) to actively favour or even exclude lithium-ion. ENDURIUM’s safety profile is a major advantage.
• UK Front and Centre: The UK’s LDES Cap and Floor Scheme is a game-changer. The strategic partnership with Frontier Power targeting up to 2 GWh of Invinity batteries specifically for this scheme underscores the massive potential.
• Deals Getting Bigger: Average deal size has surged 315% in 2025 YTD vs 2024, moving the company firmly towards the gigawatt-scale projects needed for profitability.

CEO Jonathan Marren puts it bluntly: “The rhetoric on batteries was notably transformed throughout 2024… The opportunity ahead of us is enormous.” Recent grid outages in the UK and Europe only amplify the urgency for LDES solutions like Invinity’s.

Leadership & Execution: The Marren Doctrine

Since taking the helm in September 2024, Jonathan Marren set five clear 12-month goals. Progress is tangible:

1. Revenue Targets Met: Hit revised forecasts via shipments like the 4 MWh project with EDF Renewables NA and the first ENDURIUM to Gamesa.
2. ENDURIUM Launched: Delivered on time for general sale by end-2024.
3. Commercial Pipeline Advancing: Secured the Frontier JV (2GWh), a 10.8 MWh repeat order in Hungary, and progressed the 20.7 MWh LoDES project (potentially Europe’s largest VFB).
4. Cost Reduction On Track: The 24% cost cut on ENDURIUM speaks for itself.
5. Operational Efficiency: Streamlining via UK redomicile (reducing cost/complexity) and ERP implementation.

Marren acknowledges challenges remain, particularly in scaling manufacturing and converting pipeline opportunities into firm orders amidst lithium price volatility. However, the tone is one of focused confidence: “I firmly believe we are in a strong position to take our place at the forefront of this shift.”

The Bottom Line: Positioning for the LDES Surge

Invinity’s 2024 was a foundational year. It sacrificed near-term revenue to:

• Launch a competitively priced, next-gen product (ENDURIUM) validated in the field.
• Secure a war chest (£32.4m cash) providing ample runway.
• Position itself squarely within lucrative, policy-driven LDES markets favouring its technology.
• Demonstrate serious progress on crucial cost reduction targets.

The AQSE delisting (retaining AIM) simplifies the structure. While the path to profitability hinges on converting the substantial pipeline (especially the gigawatt-scale LDES opportunities) and further cost-downs, the pieces are now strategically aligned. Invinity isn’t just building batteries; it’s building the infrastructure for a more resilient, renewable-powered grid. The next 12-18 months will be critical in proving they can execute at the scale the market – and their investors – demand.

Key Watch Point: Progress on converting the Frontier Power JV and other large LDES scheme bids into firm orders, alongside hitting the next ENDURIUM cost reduction milestones, will be the true barometers of success in 2025.
