From flip to hold: 20+ years of PE investment in B2B events
Private Equity has been investing in the events industry for longer than the 20+ years I have been in it as an Operator, Executive (ITE / Hyve / Tarsus), and now Advisor. The model has been fairly consistent: buy good assets, back great teams, professionalise the business, unlock M&A, scale the asset, and exit. But are we now reaching a different point in the cycle? Are the best event platforms becoming assets PE wants to keep compounding, rather than sell on?
The latest CloserStill deal certainly looks that way. The reported £1.35bn valuation is eye-catching, but the real signal is quieter: Providence stayed in and brought in their co-investor from Hyve, Searchlight. That may tell us more about where the events industry is heading than the valuation itself.
Events PE M&A deal valuations by year
Total disclosed / estimated transaction values by year, with a 3-deal rolling average. Values are approximate GBP equivalents and mix reported transaction values, enterprise values and valuations where only those figures are publicly available.
Notes: bars aggregate annual totals. The moving average is calculated on the underlying deal sequence and shown once per year using the year-end value. Excludes Canon / UBM, Mack Brooks / Reed, undisclosed transactions, non-valued platform formations, and Informa / UBM as a strategic mega-deal outlier.
The chart above shows a clear re-rating of the sector. The annual totals are uneven because the dataset depends on disclosed or estimated values, but the direction is hard to miss: early transactions were often sub-£200m, with occasional spikes, while the post-2013 period increasingly features platform-scale deals. By 2019, 2023 and 2026, the annual totals are being driven by larger, more institutional transactions: Tarsus, Hyve, Easyfairs, Nineteen and CloserStill. The important point is: the ceiling has moved. Events have gone from mid-market M&A territory to a market where £500m–£1bn+ platform valuations are credible when the asset has scale, vertical strength, rebook, data, M&A potential and management depth.
Now let’s have a look at the extended data behind this chart:

Looking at this, a few eras emerge:
Setting the Scene: Events Become Investable - until 2013
Before the mega-deals, the groundwork was being laid. This was the period when private equity and strategic buyers started to carve out, professionalise, scale, and sell Events businesses.
The Long Growth Cycle: Platforms Get Re-rated - 2013 to Covid
Onex’s acquisition of Nielsen Expositions for $950m in 2013 was a major milestone. Suddenly, events were not just mid-market buyout opportunities. They were large-scale platforms. Then the pattern accelerated. Inflexion backed CloserStill. Charterhouse bought into Comexposium. Providence bought Clarion, then sold it to Blackstone. Providence later bought CloserStill. Charterhouse took Tarsus private. The strategic market also set a high bar. Informa’s £3.8bn acquisition of UBM in 2018 was not a PE deal, but it mattered. It showed what strategic scale in B2B events could look like. It also told PE owners that large event portfolios could attract serious strategic value when they had the right shape. This is where I spent most of my exec time during the ITE→Hyve transformation.
Covid Recalibration: The Industry Refuses to Die - 2020 to early 2023
All of a sudden, everything stopped. COVID was the ultimate stress test. Events businesses went from highly cash-generative to operationally frozen almost overnight. Venues closed. Calendars disappeared. Forecasting became guesswork. The industry entered uncharted waters. This could have broken the investment thesis.
- It did not -
The underlying customer need did not disappear. Buyers and sellers still needed markets. They still needed trust. They still needed discovery. They still needed commercially useful moments of concentration. I’ve argued before that business events are handshakes businesses; they compress trust, discovery, and commercial intent in ways that digital channels struggle to replicate on their own.
We’re So Back: Flip Assets Become Compounding Assets - 2023 to now
Informa’s acquisition of Tarsus from Charterhouse in 2023 was the moment the market really reopened. This deal told the market that large events platforms were back in play, and that strategics would still pay for the right assets. Providence and Searchlight took Hyve private. Cobepa and Inflexion recapitalised Easyfairs alongside founder Eric Everard. Phoenix moved Nineteen into a continuation fund rather than selling.
And then came the latest CloserStill deal.
This is where the story changes. The old model would have been simple: Providence sells, another fund buys, the asset moves on. Instead, Providence stayed in and brought in Searchlight, its co-investor from Hyve. Clearly, the smart money sees more upside in staying and compounding rather than cashing out and taking their money somewhere else.
Let’s have a look at these patterns in detail:
Major announced deals, 2004–2026. Log scale. Bubble area is proportional to reported value. Coloured arrows connect repeat ownership of the same asset. Numbers refer to the source-table row.
Note on the Emerald track: the 2017 figure ($263.5m) is the IPO gross offering size, not the company’s full market capitalisation; the dashed connector to the 2013 Onex acquisition value is therefore not directly comparable and is shown only to indicate continuity of ownership.

Sincere thanks to my brilliant assistant, Claude, who put this visualisation together.
In the beginning, events were carve-out opportunities. Then they became professionalised platforms. Covid tested whether the thesis was real. Now the strongest assets are being treated as compounding platforms, all while the next generation is being assembled underneath that story, through Arc, ROAR, Opus Origin, and EVG.
That is why the CloserStill deal matters. It is not an isolated deal. It is the latest marker in a 20-year shift:
From flip assets to keep assets
A closer look at the CloserStill arc proves this: Phoenix (2014) → Inflexion (2015) → Providence (2018), and they were clearly heading for a fourth flip. But May 2026 broke the pattern: Providence didn't sell out, Searchlight came in alongside at a £1.35bn / $1.77bn valuation. That's a co-control recapitalisation, not an exit. Same fund stays in the asset, brings a partner, takes some chips off, holds for the next leg. Searchlight's own messaging ("alongside Providence... next phase of growth") explicitly markets the partnership rather than the handover.
This is the structural shift. And it's not isolated:
Onex bought Nielsen Expositions / Emerald in 2013, floated a minority stake in 2017, but never really gave up control. Today, Emerald remains listed on the NYSE, but Onex-affiliated funds still own about 93.2% of the company.
Nineteen Group, Sept 2024: Phoenix moved it into a £200m continuation fund (Kline Hill, Ares co-leading) rather than selling. Same logic, keep the platform, recycle LP capital.
Comexposium, 2018–19: Charterhouse exited not to another PE fund but to Crédit Agricole Assurances. Insurance capital is functionally a buy-and-hold owner.
Easyfairs, 2024: Cobepa (a Belgian holding company, not a closed-end fund) plus Inflexion took shares alongside founder Eric Everard. Long-dated capital, not a flip vehicle.
So three different mechanisms: continuation funds, insurance balance sheets, and evergreen holdcos, are all converging on the same thing: keeping good event platforms in the same hands for longer. CloserStill is the most visible because of the headline number, but it's the trend, not the exception.
Average PE ownership tenure by year
Average tenure of disclosed PE / PE-style events ownership cycles by exit, continuation or recap year, with a 3-deal rolling average. Tenures are approximate and rounded to one decimal place.
Notes: tenure is calculated from PE / PE-style entry to exit, continuation fund, or recapitalisation event. Where exact completion months are not consistently available, approximate dates have been used. Ongoing holdings without a clear recap / exit point are excluded.
The chart above solidifies that story. Across the disclosed PE ownership cycles in this dataset, average tenure at exit or recap has gone from around three and a half years in the mid-2010s to closer to six since 2023. The post-2023 cohort runs longer at every data point: Charterhouse's exit from Tarsus at 3.8 years, Phoenix's continuation fund on Nineteen at around 5.5, and the new CloserStill recapitalisation at roughly 8 years and counting for Providence.
The chart, by definition, only includes cycles that have already produced an exit, a continuation fund, or a recap. The longest current PE hold in B2B events doesn't appear on it: Blackstone has owned Clarion since July 2017, which is now into a ninth year. Easyfairs (Cobepa and Inflexion, 2024) and Hyve (Providence and Searchlight, 2023) are both ongoing and excluded for the same reason. In other words, the trend visible in the data is being held back by what's invisible to it: deals that have already been held longer than any dot on the chart, but haven't "completed" in a form the dataset can capture. The structural shift toward longer holds is real, and the chart, if anything, understates it.
The Strategic Exit Bottleneck
At the other end of the spectrum, Informa sits almost alone. The UBM 2018 (£3.8bn) and Tarsus 2023 ($940m EV) deals top these charts for a reason. Informa is the only buyer big enough to absorb assets at PE-prime exit prices, softened by significant “synergies” and turn them into balance-sheet earnings. Reed/RELX bought Mack Brooks in 2019 (~£200m) but has been quiet since.
As we all know, there isn't a third strategic player of comparable appetite or size. Which means: PE owners selling at the upper end of the size curve have one realistic strategic exit, and that creates pressure to do something other than wait for Informa to call. Co-control deals and continuation funds can partly be seen as a response to that thin strategic bid. (Who’d go for an IPO these days?)
What does the future hold?
The best platforms are becoming too valuable, too scarce, and too compounding to be treated as simple pass-the-parcel assets. With only a thin strategic buyer universe at the top end, and with organic growth, M&A, data, digital products, and year-round communities still underdeveloped across much of the sector, the smartest capital is choosing to stay closer for longer.
The new question for event owners is no longer simply “who buys next?” It is:
Who has the patience, structure, and conviction to keep compounding?
If you're an executive or board member sitting with that question, the value creation, data, digital, marketing, and M&A foundations underneath it are what I help with. The Event Strategy Bot covers the first mile of that thinking for free, if you'd rather start there.
