Something structural shifted in Energy, Minerals and Resources (EMR) capital allocation during 2025, and the first half of 2026 has confirmed it. Boards that once defaulted to organic growth, building new capacity through their own capital projects, are increasingly buying that capacity instead. Deal values surged even as deal counts fell, meaning fewer, larger transactions built around portfolio repositioning rather than opportunistic consolidation.
The drivers are rational. Organic delivery has become slower and less predictable, experienced owner teams are scarcer, and investors reward capital discipline over greenfield ambition. Yet the same delivery weaknesses pushing boards towards acquisition also undermine the value case for the deals themselves, because in this sector, synergies are capital projects.
This post examines what the 2025 and early 2026 data shows, why acquisition has displaced organic growth as the default capital lever, where deal value cases typically break down, and what boards should verify before and after a transaction.
What Changed in Energy, Minerals and Resources M&A in 2025?
PwC estimates that global energy, utilities and resources M&A values rose 27% in 2025 even as deal volumes fell by 2%, a performance underpinned by 20 megadeals (transactions above US$5 billion) compared with six in 2024. The Americas dominated, accounting for 62% of deal value and 14 of the 20 megadeals (PwC, 2026).
Mining told the same story more sharply. S&P Global Market Intelligence recorded aggregate mining deal value doubling year on year to US$52.7 billion across 50 qualifying transactions, the highest annual figure in 18 years, in a year when 2024 had produced no transactions above US$5 billion at all (S&P Global, 2026). The emblematic transaction is the proposed combination of Anglo American and Teck Resources, which S&P values at US$27.96 billion. As of mid-July 2026 the merger remains pending: shareholder approval and clearances in Canada, the EU and South Korea are secured, China's antitrust approval is outstanding, and Anglo American guides completion to between September 2026 and March 2027.
The first half of 2026 has qualified the momentum without reversing it: PwC's mid-year outlook expects deal value to remain resilient even as volumes declined across all four EMR sectors and megadeal activity eased from 12 in late 2025 to seven in the first five months of 2026 (PwC, mid-2026). Fewer transactions, larger cheques, and portfolios reshaped around them.
Why Are Boards Buying Growth Instead of Building It?
Restructuring intent is now the sector norm. Bain & Company's survey of 859 energy and natural resources executives, conducted from December 2025 to January 2026, found that two-thirds expect an increase in portfolio restructuring, covering divestments, consolidation and closures, in their industry over the next two years. In mining the figure rises to 72% (Bain, 2026).
Behind that intent sits an uncomfortable delivery reality. Independent Project Analysis (IPA) benchmarking reported at its 2025 Industry Benchmarking Consortium shows that large capital projects have lost around 20% in execution speed over the past two decades, while average schedule slip has roughly doubled to around 18% (IPA). When building a resource position takes longer, costs more and depends on owner teams that are increasingly hard to staff, acquiring producing assets at a defensible multiple becomes the faster route to the same strategic outcome. This trade-off reflects the gap between capital strategy and capital delivery: strategy assumes a delivery capability that often no longer exists at the assumed level.
The capital allocation mix confirms the tilt. In the same year that mining deal value doubled, S&P Global's World Exploration Trends 2026 found global nonferrous exploration budgets fell for a third consecutive year, to US$12.40 billion, with grassroots exploration reaching a historic low share of total budgets as spending shifted towards minesite and near-mine work (S&P Global, 2026). The discovery front end of organic growth is being defunded while acquisition budgets expand.
Capital availability reinforces the shift. McKinsey's analysis of 2025 activity found private equity's share of energy and materials deal value nearly doubled, from 10% to 19% (McKinsey, 2026), and fresh capital keeps arriving: on 16 July 2026, Silver Hill Energy Partners closed an oversubscribed US$1.277 billion fund targeting direct ownership of US onshore oil, gas and infrastructure assets (Business Wire). Divestment activity is equally live: Johnson Matthey confirmed at its AGM the same week that its sale of Catalyst Technologies to Honeywell had cleared final Chinese antitrust approval, completing a major portfolio exit. Restructuring has moved from strategy papers into transactions.
Does the Energy Security Shock Reverse the Tilt Towards Acquisition?
The obvious objection to the acquisition thesis is that the world changed on 28 February 2026, when the outbreak of conflict in the Middle East effectively closed the Strait of Hormuz. An 18 June memorandum of understanding briefly reopened the waterway, though renewed attacks on shipping in July have left its status contested at the time of writing. The supply shock has forced governments and operators to confront energy security as an infrastructure problem rather than a procurement problem. If security now demands domestically controlled capacity, the argument runs, capital must flow back towards building.
The reallocation is real. The IEA expects global energy investment to reach a record US$3.4 trillion in 2026, with investment now driven less by climate targets than by security concerns as governments respond to the second significant energy crisis in five years (IEA, World Energy Investment 2026). Spending on electricity grids is projected to approach US$550 billion, up nearly 20% year on year, while battery storage investment is set to exceed US$100 billion. Nuclear investment now exceeds US$80 billion annually, with close to 80 gigawatts of capacity under construction across 15 countries, and natural gas investment is projected to reach US$330 billion, its highest level in roughly a decade. Governments are committing directly to critical minerals capacity through multibillion-dollar partnership and financing programmes in Canada, the United States and beyond.
Yet the evidence supports a qualification of the acquisition thesis, not its reversal. The security-driven capital is flowing overwhelmingly into electricity infrastructure, grids, storage and processing capacity, not a return to greenfield resource megaprojects. The declining trend in oil investment predates the conflict, and the war has deepened investor hesitancy by adding a layer of geopolitical risk that is genuinely difficult to price into long-cycle project models. Prices eased sharply after the June memorandum, with Brent averaging US$85 per barrel in June, US$22 below the May average (EIA, July 2026), before renewed hostilities in July reversed much of that easing. Nothing in the security shock repairs the delivery weaknesses that made acquisition attractive; the IPA execution data cited above is unchanged by geopolitics.
The governance implication cuts deeper. Whichever route a board takes, buy or build, the work now lands on the same stretched delivery system, and security-mandated projects carry a specific risk profile of their own. Programmes accelerated under national urgency are precisely those most likely to compress front-end definition, understaff owner teams and substitute momentum for assurance. The World Economic Forum's 2026 Energy Transition Index recorded energy security as the only system performance dimension to decline, falling 0.9%, driven by weaker supply diversification and a sharp 3.0% drop in reliability (WEF, 2026). The build wave that answers that decline will test owner governance at least as severely as any integration programme. The security shock does not lower the verification bar for acquisitions. It raises the bar for everything.
Where Does the Deal Value Case Break Down?
The awkward evidence base has been stable for a long time. Cross-industry research published in Harvard Business Review puts the failure rate of mergers and acquisitions somewhere between 70% and 90% (Christensen et al., HBR). BCG's two decades of M&A research across sectors point to the mechanism: insufficient or unrealised synergies are among the main reasons deals are judged failures, and buyers in public deals have retained only about 50% of identified synergies over the past 15 years, with the remainder handed to sellers through the purchase price (BCG, 2023). Published EMR-specific failure statistics are thin, so these figures should be read as directional. The sector-specific concern is structural.
Some synergies, such as procurement savings, overhead rationalisation and the accretion of an operating cash flow stream, require little near-term project work and carry correspondingly modest delivery risk. Many of the rest, in the EMR sector, are capital projects in disguise. Connecting adjacent mines, debottlenecking shared infrastructure, integrating processing facilities, rationalising logistics: each is an engineering scope with a schedule, a budget and an owner team requirement. Where the value case leans on that kind of synergy, it inherits every weakness in the acquirer's project system, the same system whose declining performance made acquisition attractive in the first place. That shortfall sits within a wider capability gap in governing capital deployment.
IPA's portfolio research adds a further warning for the post-close period. Its study of exploration and production sustaining capital portfolios, drawing on more than 50 portfolio management leaders across 16 owner companies matched to over 200 projects, found that portfolio instability and disruption, including failure to account for the aggregate resource demand placed on owner teams, contributes directly to less predictable project outcomes. Resource-limited teams experiencing turnover saw cost growth of around 24% and schedule slip above 16%, against roughly 8% cost growth and no added slip for adequately resourced teams (IPA). Merging two project portfolios is precisely the kind of disruption that research describes.
What Should Boards Verify Before and After the Deal?
The governance task is to test the deal case against delivery reality with the same rigour applied to the financial model. Four questions matter most:
- Is every synergy scoped as a project? Each synergy line should carry an engineering basis, a schedule, a cost estimate and a named owner. Aggregate numbers without delivery scopes are aspirations.
- Can the combined owner team actually deliver the combined portfolio? Integration workload lands on the same scarce professionals already stretched by existing commitments. Aggregate resource demand should be modelled before close, a discipline central to governing dual-mandate portfolio transformation in oil and gas.
- Whose governance system survives? Two assurance frameworks, two stage-gate processes and two reporting cultures cannot run in parallel indefinitely. The integration plan should state which system governs, from when, and how in-flight projects transition.
- Has anyone independent tested the assumptions? Deal teams are structurally invested in the transaction proceeding. An independent review of the synergy schedule, delivery assumptions and integration readiness gives the board a view unfiltered by deal momentum.
These questions belong in the boardroom before signing, and they remain live long after completion, alongside the broader set of questions boards should be asking about their capital projects right now.
The Discipline Behind the Deal
The shift from organic growth to acquisition is a rational response to a real problem: capital projects have become slower and less predictable, and boards are rightly unwilling to bet shareholder capital on delivery systems that underperform. The strongest case for the deal route deserves stating plainly: buying an operating asset, even at a premium, removes the permitting, community-relations and first-production timing risks that most often sink greenfield projects, and the acquired baseline production delivers strategic value even if the synergy plan disappoints. On a risk-adjusted basis, acquisition can genuinely be the superior move.
The governance point is narrower, and it survives that argument intact. The premium paid above standalone asset value is justified by the synergy layer, and the synergy layer is where mispricing hides. An acquisition transfers delivery risk rather than eliminating it: the value case still depends on projects being executed, teams being resourced and governance holding under integration pressure.
The energy security shock sharpens rather than softens this conclusion. Boards now face pressure on both fronts simultaneously: transactions justified by synergy schedules, and security-driven build programmes justified by national urgency. Both depend on the same scarce owner capability, and both are vulnerable to the same substitution of momentum for evidence. A capital commitment made under a security mandate deserves no less scrutiny than one made under a deal timetable, and arguably more, because urgency is the environment in which governance discipline most reliably erodes.
The organisations that outperform in this cycle will be those that subject the deal case to the same independent scrutiny as any major capital commitment, verify that reported integration readiness matches observed reality, and govern the post-close portfolio with discipline rather than momentum. The playbook has changed. The need for verification has not.
