BESS is a critical enabler of the energy transition, providing grid flexibility and balancing supply and demand

Widening price spreads from renewable growth create recurring arbitrage opportunities

Nuclear and coal phase-outs are creating a growing gap in dispatchable capacity

BESS relieves grid congestion by balancing supply locally

BESS closes the flexibility gap between intermittent supply and constant demand

Secured grid access next to one of Germany's largest substations in the South - with most of the large-scale BESS projects located in the North and large demand clusters in the North, resulting in a strategic advantage

SKM will have direct access to the 400kV transmission grid, allowing for its significant scale of ~1GW and 4GWh, making it one of the largest BESS projects in Europe

The site will have privileged status, with land already secured for up to 75 years, allowing for a much more long-term outlook than other projects

As a local player, ADSE has established connections with local stakeholders, suppliers and grid operators, reducing the site's risk exposure

Full technological and IT integration based on ADS-TEC's in-house systems and expertise enabling highest operational and safety standards

Full in-house operations capabilities reduce third-party risk and ensure long-term plannability for offtakers and operators

Co-location with solar PV on-site to supply self-consumption needs reducing operational costs

Project size makes it attractive for contracted revenues through tolling and capacity markets, lowering capital costs

Project SKM is expected to reach RTB (Ready to Build) in Q3 2026

Market Description Key value driver Market outlook assessment1

Day ahead

Day-Ahead markets are the largest and most liquid wholesale markets. Batteries can participateby anticipating and discharging during high-price hours.

The key value driver on day-ahead markets for batteries are Day-Ahead spreads, i.e. the volatility between high and low prices

Spreads expected to increase in mid-term

Intraday

Intraday markets enable trading until a few

minutes before delivery. By optimizing on Continuous Intraday markets, batteries can arbitrage across energy markets

The key value driver on Intraday markets are

both Intraday Spreads as well as the ability to optimize across different timescales on Intraday Continuous markets

Spreads expected to increase in mid-term

aFRR

aFRR markets require fast response times, allowing batteries to bid capacity and energy products to the transmission grid operator (TSO) as an ancillary service

aFRR capacity and energy prices as well as the opportunity cost to participate on ancillary markets

Competition on Ancillary markets to increase

FCR

FCR is the fastest ancillary services, with

activation times of 30 seconds. Batteries can bid capacity to the TSO to reserve their availability to stabilize grid frequency

In the past two years, a 4h BESS asset trading on all markets currently available in Germany1) would have achieved gross profit of around 243 EUR/kW

An exemplary 4-hour asset participating on all available markets without restrictions and unexpected unavailability could have earned gross margins of around 243 EUR/kW, with individual months allowing margins of up to 400 EUR/kW

The margin stack is dominated by Day-Ahead and aFRR capacity markets, the former because 4h-assets can benefit from longer spreads and the latter because aFRR capacity market prices have been increasing in the past years

Compared to assets with shorter durations, 4h-assets earn more of their margins on wholesale markets

Assets with longer durations earn more of their total margin on wholesale markets, i.e. the Day-Ahead and Intraday markets, as they can benefit from longer spreads than 1-2h assets. In the long-term, this is likely going to be an advantage, as 4h-assets will be less exposed to market saturation on the smaller ancillary markets

Market outlook

Historical financials

A Appendix

Renewables create supply-demand mismatches… …leading to volatility and a greater need for flexibility

Europe's energy system is under structural stress

Russia's war against Ukraine, dependence on fossil fuel imports, and rapid renewable integration have increased costs and volatility, threatening competitiveness and grid stability

Supply-demand imbalances are becoming more frequent

Weather-driven renewable supply creates surpluses during low-demand periods, straining the grid and increasing price volatility, as well as a sharp rise in negative wholesale prices

Rising volatility highlights the need for flexibility

Beyond high prices, increasing volatility underscores the need to ramp supply or demand as electrification, EV adoption, air-conditioning use, and data-centre growth accelerate

Battery storage helps close the flexibility gap

Battery storage absorbs excess generation and supplies power during peaks, reducing curtailment, stabilizing prices, and improving renewable utilization

Revenue grew significantly from EUR 26.4m in 2022 to EUR 107.4m in 2023, partly reflecting the release of delayed deliveries from the prior years supply chain disruptions

2025 was a structural transition year, with emphasis on pipeline building, rolling out the CPO operator model, sales-team restructuring, and a shift in customer focus toward higher-quality leads

Despite lower overall revenue, service revenue doubled and C&I launched a new container product in Q4

The company posted the first positive gross profit EUR

19.4m in 2024, driven by an 18% reduction in cost of sales from EUR 110.3m in 2023 to EUR 90.6m in 2024

Inventory write-downs of EUR 10.2m were recognised in cost of sales in 2025, reflecting valuation adjustments within raw materials and finished goods during the period

EBITDA improved significantly from EUR (39.7)m in 2023 to EUR (1.9)m in 2024, a ~EUR 38m turnaround driven by improved operational efficiency

For 2025, the weak performance was largely driven by the insolvency of a key customer in the legacy

EV-charging hardware business combined with a cost base built for growth and a strategic pivot toward new business models that had not yet translated into revenue

R&D continued to work on new CBX 2.0 and skilled staff was kept to be available when sales regain momentum

42.3 42.4 42.7

Relative to revenue, COGS increased in 2025 due to underutilization of production plant due to low sales and write down of inventory

34.3

Higher opex in 2025 driven by increased SG&A and continued investments in R&D, despite lower sales

SG&A mainly consist of personnel expenses, legal and consulting fee and other expenses

G&A comprises holding expenses, administration staff, site administration charges and warranties

Other expenses include exchange rate losses, provision for onerous contracts, warranties, other expenses, and Impairment gains (losses)

R&D expenses is expected to stay at 7.5% of sales due to development of new CBX 2.0 to be launched H2'27

Selling expenses will be tightly managed and staff increased along increasing sales

Current liabilities

Total assets declined from EUR 145m in 2024 to EUR 96m in 2025, primarily reflecting lower current assets

The decrease in current assets was mainly driven by a

~EUR 20m reduction in trade and other receivables and

~EUR 6m in inventories

139

124

90

Total liabilities decreased, mainly due a reduction of warrant liabilities, repayment of loans and lower trade and other payables

The company has historically been financed predominantly by equity and shareholder capital, supplemented by hybrid and short-term borrowings

The main components of the company's asset base are inventories, receivables and cash

Inventories stood at EUR 57m in 2025, consisting mainly of raw materials, WIP and finished goods for charging and BESS systems

Intangibles consist primarily of capitalised development costs and software (e.g. ChargeBox and ChargePost platforms)

Inventory write-downs of EUR 10.2m were recognised in cost of sales in 2025, reflecting valuation adjustments within raw materials and finished goods during the period

Trade receivables declined materially in line with lower delivery volumes, from EUR 14.9m in FY 2024 to EUR 8.0m at Q4 2025, consistent with lower revenues

Working capital is currently highly dependent on inventories. Focus on selling off the finished goods in stock and clean up the position

In 2022, investments were primarily directed toward the production facility (EUR 8m) and internally generated intangible assets (EUR 3m)

In 2023, investments focused on the production facility (EUR 2m), internally generated intangible assets (EUR 5m) and R&D laboratory equipment (EUR 1m)

In 2024, investments remained focused on the production facility (EUR 1m), internally generated intangible assets (EUR 0.5m) and R&D laboratory equipment (EUR 0.5m)

In 2025, the first investment in CPT for O&O was made (EUR 1m), alongside internally generated intangible assets and R&D laboratory equipment (EUR 0.5m each)

The battery supplier went bankrupt in October 2025, consequently, a delay in the roll-out of own CPT in O&O until the new product in H2 27 is available

In the meantime, we will install CPT that customers bought in 2024 on our contracted sites, operate the chargers for them and share the profit generated
