Global M&A hits record $2.8 trillion in H1 2026 as industrial manufacturing deal value climbs 28% to $173 billion

Global merger and acquisition activity hit a record $2.8 trillion in the first half of 2026, up 48% year-on-year and the highest year-to-date total since LSEG began tracking deals in 1980, according to Reuters. Within industrial manufacturing, the numbers tell an equally striking story: PwC's 2026 midyear outlook found sector deal value climbed to $173 billion over the past year, a 28% increase over fiscal year 2025's $135 billion. The common thread across both datasets is the same: AI infrastructure, grid modernization, and defense-linked assets are pulling capital at a pace that is rewriting what counts as a normal deal.

Mega-deals are rewriting the rules of scale

Forty-seven transactions above $10 billion closed in H1 2026, totaling more than $1.3 trillion and accounting for nearly half of global deal volume, according to LSEG data cited by Reuters. That is the highest first-half total for mega-deals on record, and includes marquee transactions such as NextEra Energy's $66.8 billion merger with Dominion Energy and SpaceX's roughly $60 billion acquisition of Cursor.

The concentration at the top end is deliberate. Ivan Farman, co-head of global M&A at Bank of America, told Reuters that a $1 billion to $3 billion deal demands nearly as much management time as a far larger one, so when a transformative opportunity appears, boards are moving. BCG's mid-2026 analysis counted 31 megadeals at or above $10 billion in H1 2026, up from 17 in the same period of 2025, calling it the strongest first-half total since the 2021-2022 boom.

In industrial manufacturing specifically, PwC found that transactions above $5 billion now make up 56% of deal value, a dramatic shift from 18% in fiscal year 2024. Even excluding mega-deals, the average industrial transaction size grew 31% from FY2024 to $169 million, and average deal values have climbed from $155 million in FY2024 to $288 million in FY2025 to $375 million in the latest annual period, a 139% increase in two years, per PwC.

Three demand streams are concentrating industrial value

PwC's report identifies what it calls convergence as the defining structural force: AI infrastructure, grid modernization, and defense and resilience spending are all drawing from the same constrained industrial supply base. Power equipment, thermal management, automation and controls, and advanced components sit at the intersection of all three demand streams, which is why they command premiums of 15% to 30% above sector medians, peaking in AI compute and data center-exposed assets, according to PwC.

From 2021 to 2025, industrial manufacturing logged 155 convergence deals totaling $532 billion in transaction value, more than any other industrial subsector, PwC reported. That backlog of activity is not slowing. BCG's analysis found that AI is reshaping competitive dynamics faster than most companies can build capabilities organically, increasing the urgency for acquisitions in sectors where falling behind is structurally costly.

The capital intensity of AI buildout is also spilling across adjacent sectors. BCG noted that energy, semiconductors, and digital infrastructure are all seeing increased M&A activity driven by the demands of AI deployment. Reuters reported that technology led all sectors with $649 billion in announced H1 2026 deals, yet BCG's M&A Sentiment Index gave technology its lowest sector reading, reflecting a sharpening divide between infrastructure-layer assets commanding premium valuations and traditional software companies under structural pressure.

Strategic buyers dominate; divestitures are accelerating

Private equity remains active in the upper mid-market, but strategic acquirers are driving the volume. According to PwC, strategic buyers account for 86% of the last twelve months' deal value and 86% of year-to-date 2026 volume in industrial manufacturing. That dominance reflects a deliberate shift: buyers are acquiring AI capabilities, supply chain positions, and defense-adjacent assets that cannot be built in time organically.

The flip side of that acquisition push is a wave of divestitures. Honeywell's three-way separation is the most visible example, but PwC found that among industrial companies executing acquisitions of $5 billion or more since 2021, nearly 69% also divested during the same period. For serial acquirers, that figure rises above 86%. The carve-out pipeline spanning advanced materials, automation components, and energy transition assets is active, and PwC warns that the most attractive assets will not wait for macro clarity.

Cross-border deal value reinforces the portfolio reshaping thesis. PwC found that cross-border transactions reached 56% of the last twelve months' total, up from 30% in fiscal year 2022, driven by supply chain reconfiguration and reshoring investments. U.S.-targeted deal value nearly doubled in fiscal year 2025 to $72 billion. Reuters cited Morgan Stanley's head of EMEA M&A, Jan Weber, noting that pipeline momentum has accelerated over the past six weeks, with growing cross-border, strategic deals signaling further activity ahead.

What the numbers mean for procurement and operations teams

For operations and procurement leaders, the M&A surge is not a capital markets story. It is a supply base story. When strategic acquirers consolidate power equipment suppliers, thermal management vendors, and automation controls companies at premium valuations, supplier rosters compress and pricing dynamics shift. PwC is explicit: buyers now require evidence of AI productivity gains in the income statement, including throughput improvements, labor cost offsets, and predictive maintenance savings, before committing to premium valuations. Suppliers unable to show those gains are losing negotiating position.

BCG's overall sentiment index sits at 84, still below the long-term average of 100, which means the recovery is real but selective. Smaller deal volumes remain subdued, and confidence has not spread evenly across sectors or deal sizes. For operators evaluating technology vendors or industrial partners, that selectivity matters: assets serving two or three of the converging demand streams, AI, grid, and defense, carry durable pricing power. Assets serving only one face a narrower competitive set and more selective buyer interest, according to PwC's analysis.

The pace is not expected to slow. Bankers quoted by Reuters say boards are actively pursuing long-held aspirational deals, aided by an easier regulatory backdrop in the U.S. and proposed European rule changes to facilitate the creation of larger regional champions. In Asia, governance reforms are expected to unlock Japanese corporate cash reserves for further cross-border activity. The second half of 2026 will test whether AI-driven valuations hold as the first large technology IPOs price into public markets, but for industrial operators, the structural consolidation of the supply base is already underway.
