2025's blowout market: when M&A blew the doors off

Exit Mode recorded 454 published deals in 2025, by far the biggest year in the archive. That number matters because it changes the feel of the market. In a middling year, standout transactions tell the story. In a hot year, the story is repetition. Cvent Atlanta acquires ON24, Novacap acquires Integral Ad Science, Rithm Capital acquires Paramount Group and Centrica plc and Energy Capital Partners acquire Grain LNG span different sectors, structures and buyer types, yet they all carry the same underlying message. By 2025, buyers were no longer testing the water. They were competing inside it.

Exit Mode's view is that 2025 was the year M&A blew the doors off. That does not mean every deal was brilliant. In fact, hot markets are usually harder to read because strong assets and weak assets both find a bid. The difference is that the best buyers move faster, the average buyers get dragged into auctions they would have avoided a year earlier, and founders start mistaking abundant interest for permanent leverage. The 2025 archive is useful because it shows what a genuinely active market looks like at ground level: more take-privates, more cross-sector volume, more infrastructure and energy appetite, more sponsor willingness to write checks, and more evidence that late-cycle behavior had started to creep in.

Buyers competed hardest for assets they could own outright

One striking feature of 2025 is how often the cleanest outcomes were full-control deals. Cvent Atlanta acquires ON24, Novacap acquires Integral Ad Science, Rithm Capital acquires Paramount Group and Tropic Purchaser acquires Alexander & Baldwin all point in the same direction. Buyers did not want partial exposure to these businesses. They wanted the ability to reshape them away from public-market pressure and capture the whole upside themselves.

That is a defining feature of hot M&A conditions. Once capital gets comfortable again, control becomes more important than optionality. In soft markets, buyers like structures that preserve room to change their mind. In hot markets, the best buyers worry more about losing the asset than about paying a clean premium. Founders should take that seriously. When several buyers want the company for ownership reasons rather than curiosity reasons, the process changes. Timelines compress. Terms can improve. But discipline matters more, not less, because the temptation to treat every inbound conversation as interchangeable becomes dangerous.

The hottest markets spread beyond software into hard assets

Another useful lesson from 2025 is that a true boom does not stay confined to one fashionable category. Project Aurora Bidco acquires Spectris, Blackstone Europe acquires Big Yellow Group, Centrica plc and Energy Capital Partners acquire Grain LNG, Serica Energy acquires Prax Upstream and Buho Infrastructure acquires Whirlwind show activity running through industrials, storage, energy and infrastructure as well as software.

That breadth is what separates a strong quarter from a full market phase. When software is hot, founders can talk themselves into thinking the year belongs to one narrative. When energy terminals, upstream assets, storage portfolios and industrial groups are also moving, the simpler explanation is that capital has become willing to transact across the board. That does not remove sector differences. It does show that the market's center of gravity has shifted from caution to competition. In 2025, buyers were not just paying for digital growth stories. They were also paying for durable assets with operating leverage and strategic scarcity.

Strategic consolidation got bolder as confidence rose

A third pattern is how much strategic buyers were prepared to do once the market opened fully. Coursera acquires Udemy, Gildan acquires Hanesbrands, QuinStreet acquires SIREN GROUP AG d/b/a HomeBuddy and Burke & Herbert Financial Services acquires LINKBANCORP are different transactions with different structures, but they all suggest the same shift. Strategic buyers stopped acting like capital preservation was the first priority. Scale, audience ownership, product adjacency and distribution density moved back to the front of the agenda.

For founders, this is where a hot market becomes both useful and misleading. Useful, because serious strategics can justify faster decisions and better prices when the fit is obvious. Misleading, because a late-cycle environment can make every strategic story sound cleaner than it is. Not every buyer thesis survives integration. Not every premium survives the next turn. The founders who do best in these years are usually not the ones who tell themselves the cycle will keep improving. They are the ones who use buyer urgency while it exists.

Late-cycle noise appeared alongside the strength

The fourth lesson from 2025 is the one founders least like hearing. Hot markets carry weak deals too. STONEPEAK acquires OUTPOST SOLAR SELLCO, JIP acquires MITSUBISHI LOGISNEXT, APOLLO FUNDS acquires CLUB ATLETICO DE MADRID and Blackstone Europe acquires Big Yellow Group all sit somewhere on the line between conviction and complexity. Some are in review. Some remain at firm intention. Some carry category logic that is easier to admire than to underwrite cleanly.

That is normal for a market running this hot. Competition pushes good assets into sharper auctions, but it also lowers the social cost of pursuing marginal situations. Buyers start believing they can fix more, finance more or clear more than they probably can in a colder year. Founders should read that as a timing lesson. The best window inside a hot market is usually before the excess becomes obvious to everyone else. By the time the market starts carrying messy deals with confidence, the next chill is no longer a distant abstraction.

The pattern

What ties 2025 together is not just volume. It is compression. More deals, more urgency, more buyer overlap and less patience between first interest and serious process. That compression helped strong founders because it created real choice among buyers. It also created noise because the cycle made more assets look financeable and more stories sound durable than they really were. A hot market is not simply a generous market. It is a market that rewards quality quickly and flatters mediocrity for a while.

Founder's Lens

Adam J. Graham's read on this year: 2025 is the year I would have told founders to move faster than felt emotionally comfortable. In hot markets, the mistake is usually not that founders sell too early. It is that they assume another six months of buyer appetite is guaranteed because the last six were strong. Looking back from 2026, the best exits from 2025 came from founders who recognised that real leverage is temporary, ran clean processes with quality buyers and did not confuse a crowded inbox with an endless window.

What it means today

The 2025 lesson for founders in 2026 is blunt. If the market is genuinely hot, use it to trade uncertainty for certainty while the premium is available. Do not extrapolate the cycle forever, and do not let noisy interest crowd out the small number of buyers who can actually close well.
