Sector analysis · Energy M&A · May 2026

4 of our last 8 Due Diligences have been in the energy sector. This is what is happening.

In six months we ran four Due Diligences on energy companies in Spain, France and Germany. This paper maps eighteen European private capital transactions between 2022 and 2026, and reveals a structural bifurcation nobody has documented.

Key findings

Four data points that redefine how Europeanenergycapital is read.

The market reads each transaction as an isolated deal. The data shows a systematic pattern of European mid-market capital concentrating in Iberian, French and German energy, with a structural bifurcation running in parallel.

The market calls itgreen energy. Investors treat it as four asset classes.

An institutional pension investor entering Antin Fund V and a family office co-investing in a waste-to-energy deal are not buying the same risk. They share the macro theme, not the return thesis.

The finding nobody is mapping

While Antin pays 866M for Opdenergy, DVC Partners takes 80% of Soltec for30M.

The renewable market in Spain is not a monolith. Two currents of capital are entering simultaneously for opposite reasons: strategic capital paying a premium for quality assets, and distressed capital entering at survival valuations in over-leveraged operators.

Urgently negotiating a solution to its debt. Creditor stack: ICO (≈€50M), a Chinese bank, US insurers. Structure of guarantees, sureties and leverage over project finance.

The key to the contrast:Univergy's stack (ICO, Chinese banks, US insurers) is structurally different from the transactions analysed in this paper, which are infrastructure-fund equity with a signed PPA. The burned creditors sized their debt on 2021-2022 spot prices, which fell from roughly €200–250/MWh at the peak to €20–50/MWh during periods of 2024-2025 on excess solar and grid congestion. Infrastructure funds with long-term PPAs do not carry that exposure.

Discussion · Questions this paper does not close

Rational concentration of capital or asector bubble?

Capital is entering with logic. But the underlying market has stress points that are not fully discounted in the valuations of the 2022-2025 deals.

Question 01

Does the distressed bifurcation anticipate a consolidation cycle?

Soltec, Prodiel and Univergy are three cases in seven months. If the pattern continues, the rescued assets will be candidates for sale to infrastructure funds in 2026-2028. How many more projects are in a similar situation and have not yet surfaced?

Question 02

Grid bottleneck: the variable the models do not incorporate.

The Spain-France interconnection remains the historical bottleneck for cross-border PPAs. The ENTSO-E 2026-2030 plan may unlock value, or confirm that some deals embedded optimistic price assumptions.

Question 03

Regulatory risk: in which direction does the wave of distress push?

The Spanish retroactive cuts of 2010-2013 are in the collective memory. The current cases generate political pressure. Will the regulator intervene to stabilise spot prices? Will it extend price-floor mechanisms?

Question 04

When does the first PE buyout of floating wind happen in Iberia?

The gap of 0 transactions in floating wind will not last indefinitely. When the first buyout of an operating floating project happens, it will be a market event comparable to the first solar secondary LBO in France in 2022.

Stress point · Spanish spot price · €/MWh
2022 peaks, 2024-2025 compression
€/MWh 2022 PEAK 2024-2025 COMPRESSION
Stress · A
The spot price fell from roughly €200/MWh (2022 peak) to €20–50/MWh in 2024-2025. Deals with high merchant exposure are vulnerable if the PPAs do not cover the full debt period.
Stress · B
Compression of EV/MW multiples in utility solar since 2022 on rising discount rates. The 2024-2025 deals assume a normalisation of rates that is proving slower than expected.
Stress · C
European infra dry powder: $86.4bn in 2025, an all-time record. It creates deployment pressure that can degrade pricing discipline when the quality pipeline is limited.
Implications for the sell-side

What it means for an energy owner sellingtoday.

The window is open, but it is not uniform. The right buyer for a solar asset with a PPA is not the right buyer for a multi-technology developer or a waste-to-energy project. Positioning without that distinction leaves premium on the table.

01

The sub-sector defines the buyer, not the geography.

Antin buys operating portfolios at scale. InfraVia enters niche technology platforms: biomethane, storage, industrial decarbonisation. Asterion builds and sells Iberian conglomerates. The right process starts by mapping which fund has an active mandate for the specific asset profile.

02

The distressed bifurcation is time pressure, not just risk.

If the distressed consolidation cycle plays out in 2026-2028, it will feed restructured assets into the pipeline of active managers. That compresses the premium paid for quality assets as funds gain more options. The premium pricing window narrows with every distressed deal.

03

The advisor matters more than ever in this market.

The five most active managers are headquartered in Madrid or Paris and run funds closed in 2022-2025 under deployment pressure. An advisor with direct access to Antin, InfraVia and Asterion, who understands the difference between a PPA asset and a merchant asset, is today a material valuation differential.

Closing

European private capital is redistributing the energy of Spain, France and Germany. The question iswhich side of the tradeyour asset sits on.

We have run fourfinancial Due Diligencesin this market in six months. In each one, identifying the right buyer was the most critical decision: not every infrastructure fund looks at the same assets, nor pays the same premium, nor operates on the same calendar.

The analysis you have read describes the market as it operates today. But the market of 2027 will be different: distressed assets will have been restructured and will be competing with yours for the same capital. The premium pricing window is real and has an expiry date. If you are considering a transaction,sell-side M&A advisoryat the right moment makes the difference.

For energy owners

If you own a solar, wind or waste-to-energy asset in Spain, France or Germany and are considering a transaction in the next 18 months, the choice of advisor determines which fund you reach and on what terms.
