The takeaways
Reliability is becoming the defining investment thesis for energy, utilities, and resources M&A in the second half of 2026. The AI energy nexus we highlighted at the start of the year continues to drive much of the deal activity at midyear, but the story has broadened.
Dealmakers are now looking across the energy value chain for assets that can support three priorities at once: energy security, affordability, and efficiency. Power, grid, and gas infrastructure are becoming more strategically valuable as buyers look for capacity that can be delivered faster than many new-build projects.
Geopolitical instability is reinforcing the need for secure, domestically anchored supply. Disruption in the Middle East and concerns around critical trade routes have added volatility to energy markets and other sectors exposed to the same shipping channels, making valuation more challenging in the near term while increasing the long-term focus on supply security.
Capital is moving toward LNG, upstream gas, midstream connectivity, dispatchable generation, and grid infrastructure, reflecting an ‘all of the above’ energy strategy that balances near-term reliability with longer-term supply needs. The result is a K-shaped M&A market: deal values are being lifted by large strategic transactions where buyers can secure scale, resilience, and long-term cash flows while volumes remain softer, particularly in parts of the mid-market.
Looking ahead, acquisitions and partnerships are likely to remain favoured over pure greenfield development. Dealmakers are prioritising proven assets, stable markets, and platforms that can help meet rising demand with greater certainty.
‘Reliability sits at the heart of today’s energy deal thesis. The real challenge is balancing security, affordability, and efficiency as demand grows and markets become more complex.’
Tracy Herrmann,Global Energy, Utilities, and Resources Deals Leader, PwC USRising power demand is forcing a hard question for utilities, regulators, and investors: who pays for the grid and the generation and storage needed to serve it? The conundrum is whether these costs should be paid directly by data centres and other large-load customers, recovered through utility rates from households and businesses, or shared through new contractual and regulatory models. That choice affects affordability, project economics, and the political risk attached to new infrastructure investment.
The answer has direct M&A implications. Assets with clear cost recovery, contracted offtake, or direct exposure to large-load customers are becoming more attractive. Where the rules are less clear, buyers may face longer approvals, greater political scrutiny, and more uncertainty in valuation.
The chosen paths vary by market. In the US, regulators are increasingly focused on whether data centres should bear more of the cost of transmission, capacity, and reliability upgrades. In Alberta, Canada, deregulation gives large users more flexibility to procure or co-locate generation. In the UK and Europe, grid bottlenecks are increasing the value of network assets while also raising questions about who funds reinforcement.
For dealmakers, the best outcome is shifting toward platforms that can deliver firm power to AI without creating unsustainable cost pressure for consumers and industry. Markets with clearer rules on funding infrastructure are likely to attract more capital. Where the cost burden is uncertain, deals may become harder to price and execute.
Energy security is moving higher on the energy, utilities, and resources deal agenda as geopolitical instability, rising power demand, and supply chain disruption put a premium on reliable access to fuel and infrastructure.
The geopolitical backdrop is adding urgency. Disruption in the Middle East and concerns around critical trade routes are creating energy price volatility, which can make deals harder to value in the near term. Over time, however, the same uncertainty is likely to increase buyer interest in assets that offer secure supply, infrastructure control, and exposure to more stable markets.
Gas-weighted and LNG-linked transactions are increasingly being assessed through a supply-security lens. Shell’s proposed $16.4bn acquisition of ARC Resources is intended to strengthen its position in long-life Montney gas and provides greater connectivity to LNG Canada. Mitsubishi Corporation’s proposed $5.2bn acquisition of Aethon III reflects a similar focus on long-term LNG optionality and portfolio resilience.
Across regions, gas is being repositioned from a transition fuel to a core source of dispatchable capacity and energy security. For dealmakers, that means LNG, upstream gas, and midstream infrastructure are likely to remain active areas of M&A, particularly where assets can support reliable power growth and reduce exposure to supply shocks.
Accelerating power demand is broadening the investment response across the full generation stack. Renewables remain important, but buyers are also looking at gas-fired generation, nuclear, storage, transmission and distribution to help add capacity and strengthen reliability.
This is where the ‘all of the above’ energy strategy is becoming more visible. In mature markets, capital is moving towards brownfield generation, grid-connected assets, and platforms that can deliver capacity faster than many new-build projects. In emerging markets, the opportunity extends across power generation, network expansion, and energy-adjacent infrastructure.
Large transactions show how quickly this thesis is moving into deal activity. NextEra Energy’s proposed $67bn merger with Dominion Energy would create the world’s largest electric utility business and allow the combined company to leverage scale and operating and capital efficiencies to drive affordability for customers. ENGIE’s $14.2bn acquisition of UK Power Networks shows the rising value of regulated grid infrastructure as electrification and grid investment needs increase.
For dealmakers, speed to power is becoming a major differentiator. Assets with grid access, contracted demand, and a path to near-term capacity are likely to remain attractive, while longer-dated development projects may face more scrutiny around permitting, interconnection, and cost recovery.
Scale is becoming more important across energy, utilities, and resources, but the rationale differs by sector. In oil and gas, consolidation is focused on capital efficiency, inventory depth, and balance sheet strength. In power and utilities, larger platforms are better placed to fund rising load growth, grid reinforcement, and generation buildout.
Recent transactions show how scale is being used to strengthen position. Devon Energy’s merger with Coterra Energy reflects the continued push towards resource-anchored consolidation, combining scale with operational synergies to enhance production durability, reduce redundancies, and improve free cash flow generation. In power and utilities, NextEra-Dominion and ENGIE-UK Power Networks show how large platforms are seeking exposure to infrastructure that sits in the path of rising demand.
For dealmakers, scale alone is not enough. Buyers will need to show how larger platforms improve cost position, strengthen supply access, or create capacity to fund future investment.
Energy, utilities, and resources deal value is expected to remain resilient in 2026, even though volumes declined across all four sectors during the first half of the year.
Power and utilities continues to lead, supported by the proposed $67bn NextEra-Dominion merger, which accounted for more than half of the sector’s deal value in the first five months.
Oil and gas value is expected to rise on continued megadeal and infrastructure-linked activity.
Mining and metals showed the sharpest drop in volumes as geopolitical volatility and valuation gaps slowed dealmaking, although selected gold and critical minerals transactions continue to attract capital.
Chemicals activity remains subdued, with volumes and values down after megadeals lifted the sector in 2025.
Megadeal activity across energy, utilities, and resources declined from 12 megadeals in the second half of 2025 to seven during the first five months of 2026, with activity shifting away from mining and metals and chemicals and towards oil and gas.
For dealmakers, reliability is now a test of strategy. The winners will be those that can identify where demand is durable, where supply can be secured, and where capital can be deployed with confidence. In a more volatile market, disciplined M&A can help build the platforms needed for long-term growth.
